It is existing porcelain brick production technique batching ball milling, the deironing of sieving, go into cylinder colour mixture, spraying drying, feed bin old, pulverize, at random batch mixing, the dry stamp of compression moulding, burn till on the basis of polishing, in the compression moulding process, adopt the grid pattern of natural-like stone lines; Being adopted as in batch mixing process at random simultaneously makes the stacked clearly flush system of this pattern lines in conjunction with the intermittent type cutting mode.Its first step adds wet-milling form slurry in the ball mill after need various starting material being pressed the accurate weighing of said ratio by technical process, and slurry ball milling fineness is that 0.6g～0.8g tails over (250 mesh sieve); Slurry proportion: 1.7g/cm
3～1.75g/cm
3Slurry moisture: 33%～35%.This slurry through slurry sieve, after the deironing, homogenizing, color matching spraying drying to the moisture that needs (bed material is 6.6～7.0%, and the lining and the material moisture that bubbles are 5.0～5.6%).In order to reach the effect of hole distribution preferably, it is crucial adopting proportion, moisture and the slurry ball milling fineness of suitable slurry, lining and the material that bubbles, and through enforcement, above-mentioned scope of the present invention is ideal.
The powder of various different colours is according to the needs of design, in the cloth truck in the ratio of setting and blanking order blanking to the cloth grid and deliver to 800 * 800,600 * 600 adobes that press is pressed into to be needed.This process is beaten glomerocryst micro mist cloth, molding mode basically identical with traditional with the anti-of current trend, but in order to make product have the effect of natural cavity stone imitation more true to nature, we have improved traditional cutting mode.Traditional stacked flush system cutting mode is tiled on the distributing belt with making the powder continuous cloth of various different colours and a stacked one deck, sufficient batch mixing process is arranged at blanking during to hopper, the lines exquisiteness, and pattern is soft; The interval type cutting mode then is the at interval blanking of powder pulsed of various different colours, does not have overlappingly between powder on belt, need just can mix the formation pattern in hopper He on the grid, adopts the product lines of this cutting mode more extensive.With reference to the lines style of natural cavity stone, my company is improved to intermittently in conjunction with the advantage of two kinds of cutting modes that stacked flush system blanking reaches distinctive lines effect on stream.
Need to prove that in order to ensure the product hole distribution proportion suitable with natural cavity stone the proportioning of material in lining of bubbling is about 3～5%, in order to make special product effect, the proportioning of the material that bubbles can be increased to 15% even 18% or higher.
As Fig. 1, technical process of the present invention is described below:
Raw material is checked and accepted the examination that the into raw-material examination of factory comprises sand, stone flour, mud and various chemical industry material, colorant.Factory has formulated various standard for acceptance and by a collection of professional's operative norm, has guaranteed to use high-quality raw material various starting material according to different use propertieies, requirement.
The batching ball milling is formulated various raw-material producting proportions according to the test-results of person skilled, and prepare burden according to this proportioning, by conveying belt various starting material are sent into the 40T ball mill then, add again that the roating sphere grinding machine becomes the mud slurry with the starting material ball milling after the entry.This process approximately needed do not wait in 12～18 hours, and the time is depended on the fineness of mud slurry, and technic index requires to be controlled at 250 mesh screen residues less than 1.0% usually.Slurry after the ball milling carries out the stability of homogenizing to guarantee to produce by the underground stock tank that pipeline flow into hundreds of tons of capacity.
It is that starting material thick excessively in the production process, impurity and various foreign matter are sifted out that the deironing of sieving is sieved; Deironing is by bar magnet the irony in the mud slurry to be removed.Because these things will have very large detrimentally affect to quality product, altogether need be in the production process through three deironing of sieving.
The mud slurry of going into cylinder colour mixture front is white, has the different colours of various needs in order to make product, need add the different colorants of measuring in the mud slurry.The control of colorant add-on need constantly test be next definite by the professional and technical personnel.In order to ensure the homogeneity of colorant, colorant also needs fully to mix by high-power stirrer after adding.
The slurry of spraying drying colour mixture is through carrying out spraying drying after the deironing once more.Spraying drying is the process that the mud slurry is dried to powder.Principle is: mud slurry is dispersed into vaporific by spray gun, the warm air that comes with convection current carries out heat exchange afterwards, the moisture evaporation during vaporific mud is starched, and other ceramic raw material has just become powder.Need emphasis to control the size of vaporific mud slurry and the temperature of warm air in this process, because they have determined the grain composition and the moisture of powder respectively.
Feed bin is old because varying in size of vaporific mud slurry causes the difference of heat exchange, finally causes the moisture of powder to have any different.After powder after the spraying drying is delivered to filler bin by conveying belt, even in order to make moisture, powder need be placed 24 hours at least usually.Meanwhile, owing to having suitable temperature and moisture, the microorganism in the powder also will multiply fast and will producing favorable influence to the processability of powder.Therefore, this process is called as old.
Pulverizing different products has different requirements for the fineness of powder, and common pattern permeating tile, illusion-colour etc. do not need to pulverize, and can directly use spraying material.Micro-powder brick then needs powder is pulverized.Crushing process promptly is the process of powder being processed by specific equipment (sander or powder beater), can control the fineness of powder by regulating motor speed.
Batch mixing carries out at random by the powder vehicle device to the different colours powder that batch mixing forms the various pattern of brick face at random.Different ratios between different powder cars, cutting mode, blanking order, the powder can form various pattern in the batch mixing process.Powder behind the batch mixing is transported to the voltage supply of press die cavity by powder car parts " grid " and makes type.Most on the market product innovation all is to produce by the different processes of batch mixing at random at present.
Being molded over having shades of colour and having formed the powder of pattern through batch mixing at random of producing before this operation must be by the shape of press compacting could formation brick.The process of complexity such as the exhaust of this process by hydraulic press, compacting is discharged the moisture between powder and powder is combined closely and becomes to have the work in-process of certain intensity.Can adopt the press of the different tonnages of 2800T～7200T according to varying in size of product specification.
Dry can press-molding in order to ensure powder, spray-dired powder remains on 6.0～8.0% moisture usually, these water need by the oven dry of roller bed type dry kiln to the moisture 1.0% below to guarantee descending operation to burn till fast.Adobe in dry kiln successively the air by low temperature and high relative humidity, high temperature low humidity carry out heat exchange and exchange of moisture process, can reach processing requirement after about 40～60 minutes.
Stamp is for pattern permeating tile, and its pattern mainly forms by stamp.But the soluble salt of various color developments and water, the mixed fancy glaze that makes of penetration-assisting agent, the scraper with the flower machine makes fancy glaze be printed in the adobe by the colored net that specific pattern is arranged again, and these fancy glazes form decorative pattern through firing the back.
Burning till adobe moves in the roller bed type calcining kiln, temperature rises to 1200 ℃ from room temperature and reduces to room temperature again, series of physical, chemical transformation such as moisture evaporation, decomposition, oxidation, fusion, crystallization have taken place in the process, have finally become irreversible ceramic product.
Polishing has higher glossiness in order to make product, also need to product surface scrape, cut, post-production such as mill handles.Simultaneously, meet the requirement of relevant criterion, need the product edging is handled in order to guarantee product size.
Classification is carried out classification, color separation according to relevant criterion (national standard, enterprise's inner quality standard etc.) to product, and different grades, not homochromy number product are separately deposited.
Packing is packed, is identified and put in storage product according to the demand of product protection.
More than the preparation method of hole provided by the present invention stone porcelain brick is described in detail, used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for the general technology person of this area, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
