Abstract
The present invention relates to a kind of agricultural paper film and manufacture method thereof, is raw material with the string, with lime or urea method boiling, manufactures paper with pulp, forms through the arrangement encapsulation through special slurrying, dosing, adding assistant chemical auxiliary agent.This paper film can replace plastic sheeting, has certain wet strength, water permeability, gas permeability, has solved the problem that plastic film is difficult to reclaim effectively, strengthens organic fertility of soil simultaneously, improves soil texture.
Description
The present invention relates to a kind of paper film and manufacture method thereof that can replace agricultural plastic film, be applicable to the agricultural film culture underglass.
Existing agricultural plastic film is difficult to decompose under field conditions (factors), and pulling force is little, and is easily broken, is difficult for reclaiming contaminated soil.Therefore, the residual quantity of plastic sheeting in soil horizon is big, and long-term the use forms barrier layer easily, the soil ventilation permeability is reduced, hinder the growth of root system of plant and, cause the crops underproduction significantly moisture, nutrient absorbing, the price of plastic sheeting is higher simultaneously, and agricultural input is increased.
The object of the present invention is to provide a kind of agricultural paper film and manufacture method thereof, this paper film can replace plastic sheeting, has certain wet strength, water permeability, gas permeability is embraced soil nature, has solved plastic sheeting effectively and has been difficult to reclaim and problem of environment pollution caused, increase soil organic fertilizer power simultaneously, improve soil texture.
The present invention is achieved in that a kind of agricultural paper film, it is characterized in that this agricultural paper film contains the cellulose fibre of (representing with percentage by weight): 65-75%: the non-cellulosic fibre of 9-11%, the ash of 6-10%, the moisture content of 8-12%, the trace element of 0.1-0.5%, the nitrogen of 0.4-1.0%, phosphorus, potassium, the auxiliary agent of spraying can be waterproofing agent or herbicide or insecticide or water retention agent etc. as required on the one side at least of paper, the manufacture method of above-mentioned agricultural paper film, adopt conventional paper technology manufacturing, it is characterized in that:
The lime or the urea that add 0.2-0.5% in digestion process are made digestant;
In pulping process, be 4.5-5.5% to concentration, beating degree is the slurry pulping of 22 ± 1 ° of SR, beating degree reaches 26 ± 4 ° of SR;
In the process of manufacturing paper with pulp, the slurry concentration when advancing cylinder is 0.3-0.5%;
Before the rewinding, the paper film is dried, make that water content is 8-12% in the paper film.
The present invention is owing to replace plastic film with the paper film, the auxiliary agent of spraying is herbicide or water retention agent etc. on the one side at least of paper film, solved the drawback that plastic film exists effectively, and integrate its advantage, performance, multiple functional, have certain wet strength, water permeability, gas permeability, antifreeze cooling, windproof, anti-heavy rain, anticorrosion, preventing disease and pest, anti-compaction, prevent the loss of soil nutrient and drench, increase soil organic fertilizer power, improve soil texture, agricultural paper film price is lower than plastic film simultaneously, is about 1/3rd of its price at present.The agricultural paper bags of growing seedlings of the extension product of paper film etc. are strong to crops adaptability, and the scope of application is more extensive.
Below by embodiment the present invention is further described.
The technological process of production of agricultural paper film,
The rice wheat straw-→ chaffcutter-→ boiling-→ making beating-→ manufacture paper with pulp-→ rewinding-→ cut-→ the packing warehouse-in.
The rice wheat straw is put into production after storing a period of time again, forage moisture content 15% ± 3%, and chaffcutter length is not more than 60 millimeters, presses liquor ratio 1: 25-1: 3 dosing material, carry out boiling, use potassium permanganate (KNnU after the boiling
4) check its hardness number, the forage after the boiling to reach opening after the above standard, start the rotary spherical digester discharging, enter in the beater.To slurry concentration is 4.5-5.5%, and beating degree is the slurry pulping of 22 ± 1 ° of SR, cellulose is discongested average fiber length 0.1-0.5 micron (um), 26 ± 4 ° of SChopper of beating degree by mechanical shearing, branch silk, hydraulic blow effect.Slurry after the making beating enters the concentration 0.3-0.5% that cylinder is manufactured paper with pulp, then by squeezing, oven dry, on the one or both sides on the paper, spray auxiliary agent according to different needs again,, again the paper film is dried as waterproofing agent or herbicide or insecticide or water retention agent etc., make water content 8-12%, afterwards, batch, operation such as cut.
Product according to above method makes mainly contains (representing with percentage by weight): 70% cellulose fibre, 10% non-cellulosic fibre, 8% ash, 10% moisture content, 0.3% trace element and 0.7% nitrogen phosphorus potassium.
Following table is the properties of product of the agricultural paper film that makes.
