Description

[Detailed Description of the Invention] This invention provides that when a rice transplanter is used to mechanically plant a seedling box for young rice in a large moat, the vertical, horizontal, and vertical dimensions of the seedling box can be adjusted to prevent moisture absorption. Due to drying, it expands and contracts, making mechanical operations difficult, causing the box to tear, or planting multiple boxes, which is inconvenient.Many of the reasons are due to paper boxes' unique moisture absorption, which causes deformation. To prevent the water content in the paper fibers from being evenly absorbed by the capillary, magnetic mineral fibers such as glass fibers, rock wool, asbestos fibers, carbon fibers, metal fibers, etc.
- 40% of wood pulp, hemp pulp, or cactus fibers are mixed, beaten, colored, and made into paper sheets, and molded or vacuum pumped to produce the above-mentioned beaten mixed fibers. The paper box for seedling beds is characterized by sucking it into a steel mold, dehydrating it, molding it, peeling it off, drying it, and using it as a seedling box. Using a paper box laminated with a resin film made by mixing chitin and chitosan with a polyester resin made of carbon monoxide and formaldehyde,
When assembling, a paper box that does not expand or contract and does not hinder planting can be obtained.

Many of the general and well-known seedling bed boxes are made of paper;
When planting in soil, the moisture in the seedbed expands and contracts freely in the vertical, horizontal, and vertical dimensions, deforming the paper box of standard dimensions, which makes it difficult to set up a machine for mechanical planting. When buried in the soil, it is often used because it is decomposed by soil bacteria and recycled into the soil, but plastic materials do not easily decompose in the soil and remain. In addition, thin boxes have weak back strength, making planting operations troublesome, and UV decomposition may occur.
Fermentable polyethylene containing starch, polypropylene polyethylene vinyl acetate, polyacrylonitrile,
There are plastic boxes made of polyethylene tyrephthalic acid resin, but they all require high processing costs, and for practical purposes, it is difficult to develop seedbed boxes by improving paper pulp.
It was requested.

Therefore, a mixture of paper and plastic synthetic fibers was used, but it decomposed slowly in the soil, and the fiber cutter was inefficient, causing many problems in mass production. Moreover, since the water absorption distribution was not uniform enough, it was deformed and therefore mechanical operation was not easy, and an improvement was required.

As a mixed fiber paper whose wettability coefficient exceeds 100% when the wettability coefficient of a general paper box is 70 to 80%, magnetic mineral fibers such as glass fibers, wood pulp, hemp pulp, or cactus fibers, Coconut shell fiber mixed with shiuro fiber,
Paper made by mixing paper with mineral fibers such as glass fibers distributes the absorbed moisture evenly to the wood pulp, hemp pulp, and cactus pulp fibers, always maintaining the moisture content. When it moves within the fibers due to its capillary absorption, the movement resistance is small, especially as it is proportional to the increase in glass fibers and inversely proportional to the amount of pulp.
Pulp also has the characteristic of allowing moisture to enter and exit evenly; even if one edge of the paper gets wet, within an hour, the moisture will spread evenly throughout the paper, and during the drying period, the moisture will be absorbed into the fibers. Because of the intense movement, porosity, and dry evaporation, deformation occurs quickly when molding paper boxes. In addition, since most of the glass is made of silicates, the glass surface always forms hydrogen bonds with water, easily forming a water molecule film on the surface, and pulp fibers. and through water molecules,
However, the bond of water molecules on the vitrified surface is weaker than on the pulp fiber surface. Therefore, glass fibers such as basic fibers, slag fibers, asbestos fibers, carbon fibers, and metal fibers also exhibit similar effects, but metal fibers cause trouble and deformation during cutting. If you do, there is no restorability, so
Not practical.

Therefore, the main problem is to mix mineral fibers such as glass fibers, rock wool made from mineral slag fibers, asbestos fibers, carbonized fibers, etc. with mineral substances such as silicate floating stone powder, shirasu soil, zeolite, bentonite, clay powder, etc. When making paper from pulp fibers, 5 to 40% of the wood pulp is mixed, and when making paper, sodium alginate, polyacrylate, opuku vinyl alcohol, acetal, etc. are used as thickeners. ,
When making paper by adding starch etc. dissolved in water, the mineral fibers, which have a high specific gravity, do not separate and settle from the wood pulp, but float and have a concentration of 0.1 to 0. It is added at a ratio of 5%, put into a beating machine or a hydra pulper, and dispersed.Then, paper is made by a paper machine using X steel, short steel, or long steel. The mixture is sucked through the porous mold using a vacuum pump, then semi-dried using a conveyor dryer, then heated through a heat press, press-molded to standard dimensions, finished, dried, and then used as a nursery bed. When making boxes, you can create seedling boxes that are not easily deformed.

In addition, when synthetic fibers such as plastics are added to phosphorus pulp, the strength and stiffness are weak, and water dispersion is less than half that of glass fibers.

In addition, to provide this water resistance, parapine, hollow tar pitch, and polyvinyl resin are applied and reinforced, but in this method, a combination of polyvinyl acetalized resin and sorter calcium albinate is used. In addition, cyclized resins such as polyvinyl alcohol citrate adehyde, benzaldehyde, vanillin, cyclohexanone, acetone, polymerized resins of formaldehyde, carbon monoxide, and formaldehyde, The etherified fiber gelatin, casein protein and polyhydroxybutyrate resin on the paper surface are made by polymerization of polybricolide resin, chitin, chitosan mixture, and monochloroacetic acid chitosan solution, and are used to make wood pulp of paper boxes, mineral fibers and mineral fibers. They are laminated and used together with mixed paper boxes, but the processed ones increase their water resistance, and after being buried in the soil, they are destroyed by soil microorganisms after a certain period of time. is hydrolyzed.

Seedling bed boxes made from this mixed fiber are laminated or coated with a cyclized polyvinyl alcohol resin, which acts as an antibacterial agent against gram-negative bacteria in the soil, inhibits the growth of bacteria, and , this polyvinyl alcohol cyclized resin is mixed with sodium alginate water,
A paper box is coated in advance, and a resin liquid containing calcium chloride added to the polyvinyl alcohol cyclized resin is coated and dried, resulting in a water-resistant and non-deformable resin. These resins are decomposed in soil by soil microorganisms after several months.

Even if you apply the coating mainly to the sides and leave the bottom of the seedling bed box, and even if you plant young rice seeds, not only will deformation occur, but it will also prevent harmful microorganisms from entering the paper box, which can cause problems in continuous cropping. , it is safe and hygienic because it prevents

In addition to these, polyhydro, xybutyrate, polyglycolide resins alone, and mixtures of crab, echinochitin, and chitosan are used.

This chitosan is monochloroacetic acid or lactic acid,
When a combed chitosan gel is applied to a paper box and neutralized with alkaline water or alkaline alcohol, the problem of continuous cropping becomes smaller and the strength of the paper increases.

Also, carbon monoxide is added to paraformaldehyde under high pressure.
A polyglycolide powder system prepared by mixing and heating under pressure is heated to 200°C to form a film, which is then laminated together.

Alternatively, the polyglycolide of 2 can be mixed with polyvinyl and alcohol cyclized resin, or added to an aqueous solution dissolved in monochloroacetic acid, lactic acid, or acetic acid.
A mixture is used. In addition, boxes made of polyhydroxybutyrate, which is made from microorganisms, mixed with chitosan and chitin are used for nursery boxes.
Since it is expensive, it is advantageous to use it in combination with paper for the time being.

As mentioned above, Ikuinae Makoto paper boxes made by mixing mineral fibers with wood fibers, hemp fibers, and cactus fibers (loliugetsu fungus fibers) have lower humidity levels than paper boxes made from paper alone. The distribution is even and there is no deformation or warping even when dry, and the resin has high permeability, so we use polyvinyl alcohol cyclized resin containing antibacterial agents and arginine. The paper boxes coated with acid salts or chitin-chitosan organic acid solution and infiltrated with a mixed resin mixed with polyester of polyglycolide are used to prevent damage to continuous cropping, and can be used as paper boxes for seedling beds to improve water resistance. Paper boxes are made that do not interfere with the planting of so-called plant-planting machines, so they can be used for other vegetables, sugar beets, potatoes, carrots, burdock, etc. On the other hand, using a mixed fiber seedling breeding box coated with a lactic acid solution of chitin and chitosan,
When germinating, the plants are treated with antibacterial agents to prevent the actinomycetes stremyscens bacteria caused by abnormal multiplication, which is the main cause of continuous cropping problems.
It has the advantage of supplying soluble silicate ions, which are necessary for protection and growth, from mineral fibers, and is also effective in preventing black spot, which is caused by the proliferation of Fusarium fungi, and prevents continuous cropping failure. In particular, as a cyclized resin of polyvinyl alcohol, the cyclized resin with cinnamic aldehyde, benzaldehyde, cyclohexanone, etc. has improved its antibacterial properties.
To prevent microorganisms in the soil, add actinomycetes, bacteria, bacterial culture solution, lactic acid bacteria, bio solution, and photosynthetic bacteria to protect young seedlings. Paper boxes for seedlings that have been diluted and permeated have the effect of suppressing board club disease in the soil and suppressing bacteria and some bacteria that become food for nematodes, greatly improving agriculture. This is especially true for glass fibers, where the fibers are slippery hard glossy fibers. This is the result of considerable resistance to water movement within the fibers, and the lack of boric acid ions that occurs due to continuous cropping problems such as Chinese cabbage can be compensated for by boric acid added to the glass fibers. In addition, low-radiation silicate powder, which is used as an antibacterial agent against harmful bacteria, converts water in the soil into polymers, and is particularly effective against coral reef fossils formed by sedimentation on the seafloor. The presence of trace amounts of heavy water contained in water suppresses the growth of bacteria, so calcium silicate, magnesium, and iron concentrates with radiation properties are extremely effective. In particular, it is effective in preventing water rot from occurring due to the polymerization of water in the soil (formation of 6-membered ring molecules and 5- to 4-membered ring molecules). In addition, this pulp fiber, radiation property, and magnetic iron powder (tetroxide acid Fe, Fe2O3, which has a large magnetron content) are often used as freshness-keeping paper and are useful as packaging materials.

In addition, this mixed paper impregnated with gypsum or bentonite liquid has high heat resistance, and the bentonite resistant liquid containing rare metals has high permeability and can withstand temperatures of up to 30°C at a temperature of 80°C.
Since heat-resistant paper can be obtained that can withstand heat resistance for several minutes, it is useful as a wall material for building materials.

In addition, wall materials made by impregnating this fireproof material with plaster and dilute polyester resin or the above-mentioned cyclized resin are:
It allows moisture to flow in and out in the same way as wood, so it can be used as a substitute for wood and walls to regulate indoor temperature.

In addition, mixtures of mineral fibers, pulp, hemp pulp, and cactus fibers with resin added are used as filter paper and for separating oil and water from oil and water, and are used as fluid filter papers for oil. This is an industrially useful invention because it can be used to filter high oil content.

The manner of implementing this invention is shown in the drawings as follows.

FIG. 1 shows a process diagram of the paper box for raising seedlings according to the present invention. The raw material used for collecting waste paper first includes newspapers, magazines, cardboard, etc.
Raw materials such as thin paper cut layers and waste copy paper are prepared and sorted (2) at the sorting site.

The selected materials are used in the beating machine, such as raw waste paper, mixed and beaten Rockurul, glass fiber, and hemp raw materials, which are first cut using a rotary cutter (4), and then processed using a hydra pulper (5). In order to beat and separate the raw material shot powder, the rising fibers in the pulper tank are sucked by a pump (6) and introduced into a mixer (7), and the waste paper beaten by the pulper (8) is transferred to the mixer. Also, if necessary, mixer (

The seedlings are then planted in a greenhouse (19) with seedlings or directly planted with germinated seedlings, which are finished in a greenhouse (20), packaged, and shipped.

On the other hand, the board made by the paper machine is molded by a compression molding machine (14a), sent to a finishing press (14), and the molded product is dried by a dryer (16a) and then dried by a resin impregnation machine or a sprayer ( The seedlings are treated in step 17) and dried to make paper boxes for raising seedlings, then planted in greenhouses (19) and (20) and shipped.

FIG. 2 shows a front view of a single paper box for growing seedlings (21), inside which plant seedlings (22) are planted. FIG. 3 shows its side view.

Figure 4 is a front view of a plurality of paper boxes for raising seedlings (23). Inside the boxes (23), a large number of molded Nakagiri selections (24) are partitioned to allow individual boxes to be separated. Although it is made in
Seedlings (25) are planted in the box. Box (23)
A hole (26) is inserted into the back of the box, and soil (27) is poured into the bottom of the box.

An example of the composition of the paper boxes for new seedlings (23) and (21) is as follows.

Example (1) Waste paper pulp 100 parts Rock wool or glass fiber 30 parts Mineral powder Volcanic pumice powder or bentonite or zeolite or activated carbon 60 parts

80 parts impregnated resin 15 parts This formulation includes hydropulper (8) and mixed material (7)
The waste paper pulp is first dispersed, glass fibers and rock wool are added to prevent the mineral fibers from getting entangled, and then, after molding and drying, The impregnated resin is sprayed or deposited, dehydrated using a centrifugal separator, and dried, but drying can be carried out freely in the sun or by heating.

0% impregnated and dried.

The dimensions of this paper box for raising seedlings are a square with a side length of 6 grains, and the dimensional error of a single box with a height of 6 grains varies depending on the mixing ratio of mineral fiber, but if 10% or more is added, 1% , 30%, the change is approximately 0.5%, and when it exceeds 50%, the deformation rate is 0.1%. Furthermore, when the structural fiber is added to 80%, the deformation rate becomes 0.1% or less.

In addition, this magnetic mineral fiber rock wool is made of basic silica salt with Sio220-30% Cao40-48% Fe2o3.
The other 10% is a component system that is used as a neutralizer for soil acidity with the addition of ammonium sulfate to counteract rice blast disease, and also serves as a supplement for soluble silicic acid, which strengthens the growth of plants in seedlings. Because it is soluble, it is reduced to the soil.

Fibers such as jute, cactus, hemp, and palm fiber have increased compressive strength and tensile strength, and are more effective in preventing paper boxes made of mineral fibers from becoming brittle. It increases in proportion to the amount of mineral fiber and has the property of uniformly penetrating and drying during resin processing.

In addition, this paper box for raising seedlings with activated carbon, activated oil carbon, zeolite, bentonite, and floating stone (pumice powder) powder prevents soil contamination and suppresses plant staining, and also creates a home for Bactilia. Prevents continuous cropping.

In addition, especially radiation bentonite and floating stone powder,
■If Iishi powder is added and magnetite powder is added, the water in the box has a polymer structure, but the water structure is a 6-membered ring,
The more 5- to 4-membered rings are made and polymerized, the more the growth of Gram-negative bacteria is suppressed. This is because the field of activity is restricted in a certain direction. 4 to 40 microcuries is best, and pentonite powder in the clay of coal seams is 4 to 40 microcuries.
~12 microcuries, from good submarine descent,
The resulting calcium carbonate marble powder from coral reef fossils is
The one produced in Tetta Town in the Niimi region of Okayama has a radioactivity of 4 to 12 microcuries, and the paper box mixed with silicate suppresses bacterial growth and increases production by 20%.

When calcium lactate is added to the lactic acid solution of chitin and chitosan, it becomes coagulable, which has the effect of adjusting acidity and suppressing the reproduction of nematodes.

This is because the lactic acid ions suppress the bacteria and fungi that are the food for the nematodes.

However, if the amount of lactic acid is large, it is harmful to plant growth, so it is neutralized with lime carbonate or lime superphosphate, but calcium lactate production from radiation calcium carbonate is effective against clubroot and Fusarium disease. effective. Adding restin (soybean) to this chitosan lactic acid solution is more effective, and adding amino acids and liponucleic acid improves growth.
It gets expensive.

A cyclized resin made from an aldehyde of polyvinyl alcohol preferably has a degree of cyclization of about 1 to 2.2. If the degree of cyclization is high, hydrolysis in the soil will be delayed, and the medicinal efficacy will not be reduced. Acid aldehydes are produced by themselves to prevent hair roots of plants.
This aldehyde and cyclized resin of polyvinyl alcohol are produced and secreted from the body to protect against soil microorganisms, so this aldehyde and cyclized resin of polyvinyl alcohol can cause damage to continuous crops, and adding parapine and stearin fluoride resin powder can help prevent frost damage. The addition of foaming powder to styrofoam is useful in preventing permanent set during wintering.

When benzaldehyde and cyclohexanone are added to the cyclized resin of cinnamic acid aldehyde, in the case of symbiosis, it suppresses the proliferation of weeds and is useful as a less toxic pesticide.

In addition, when using aldehyde cyclized resins such as these, the activity of soil bacteria is temporarily slowed down due to the antibacterial effect, and nutrients cannot be provided to plants, so Aspergillus bacteria,
Ores bacteria, lactic acid bacteria, actinobacteria, photosynthetic bacteria, etc. are used in combination.

As a result, activated carbon, bentonite, calite, organic fermented fertilizer, and raw straw are dispersed in this paper box for seedling cultivation, which is useful as a habitat for soil bacteria, and by adding bioliquid, it can be used as a stabilizing material for microorganisms. It is effective as.

In addition, since polyglycolide resin and polyhydroxybutyrate are decomposed in the soil, glass fiber can also be used as lime soda glass to improve materials that are difficult to decompose like resins such as polyethylene and vinyl chloride currently in use. ,
Boracous steel and acid-containing glass fibers improve the boric acid deficiency caused by continuous cultivation of Chinese cabbage, and are useful as a source of silica-fixing ions for silicic acid plants, and those containing potassium are useful as fertilizers.

As mentioned above, the feature of this invention is that the original paper box for raising seedlings is
Seedlings deform after planting, making it difficult to operate automatic planting machines, reducing productivity and wasting the use of expensive machines. By mixing and molding cactus and coconut pulp fibers into pulp, the workability can be increased by as much as 20%. It improves the permeability of (porous) resin, increases water resistance, and suppresses deformation, making it easy to create a home for bacteria, and can also be used to prevent continuous cropping problems. It is useful as a container for drilling plants, and unlike known plastic containers for raising seedlings, it is difficult to decompose, resulting in water-retardant properties and air permeability.
Because it is expensive, especially the more mineral fibers it contains, it is used for air purification and filter paper, and is also used as automobile plywood and ceiling panels inside cars.

In addition, paperboard made by mixing mineral fibers, cactus fibers, and jute fibers with the collected material of drift pulp such as knot lees, which is produced in large quantities in the papermaking process, has a high strength based on the original short fibers of knot lees. This is an industrially useful invention as it improves the problem of deterioration and enables molding by extrusion molding in the same way as plastic molding, allowing the molding of paper boxes for raising seedlings to be made continuously, and as an effective use of industrial waste.
