Abstract
The invention is an imitation polished natural marble producing method, and its character: it includes the following steps: mixing ceramic sand, mud and other crude minerals in a certain proportion, and making into slurry by using wet-ball mill, then making molding and mill base distribution treatment on the slurry to obtain the slurry blanks distributed with mill base, then making drying in front of kiln, cauterization in kiln and polishing and milling outside kiln on these blank in sequence. The invention adopts the method of distributing mill base to molded slurry and effectively uses good fluidity, strong permeability and good transiting property of the mill base, to make the mill base able to fully permeate the slurry so as to form the fine-textured effect like natural marble. The finished product is extremely similar to natural marble, and has natural and smooth lines and good quality as well as low production cost. The processing method is diverse, enhancing the vivid effect further.
Description
Technical field
The present invention relates to a kind of production method of artificial marble, particularly a kind of production method of imitative polishing natural marble.
Background technology
Artificial marble is a kind of New Building Materials that come out newly developed in recent years.The general production method that adopts as shown in Figure 1 of present known artificial marble, and for improving the decorative effect of its finished product, satisfy the decoration requirement of user to artificial marble, existing parian is on production technology, especially on the distributing mode of press device and ooze flower, stamps etc. are technical, be gradually improved through continuous improvement, but owing to all be serve as to suppress medium in its forming method with powder (comprising super fine), and there is mobile difference in powder itself and is oozing flower, the shortcoming of transitional difference in the printing technique, cause the finished product produced in skin texture, aspects such as lines and brick face texture and natural marble differ greatly, and influence its decorative effect.As number of patent application 98125703 disclosed a kind of artificial marble of Chinese patent and production method thereof, characteristics such as although its artificial marble of producing has acid and alkali-resistance, do not absorb water and texture is sparkling and crystal-clear, but because it is to adopt aluminium hydrate powder to carry out garland and toner is sprayed at product surface aborning in process, it promptly is the compacting medium with the powder, because of there is aforesaid shortcoming in powder itself, so that the skin texture and the lines of its finished product are difficult to form natural and tripping effect, therefore can't satisfy consumers in general's demand.
Summary of the invention
The objective of the invention is to solve above-mentioned existing problems, a kind of production method that produces good looking appearance, lines are natural and tripping, true to nature, texture is good, production cost is low imitative polishing natural marble is provided, and this production method row simple to operate, easy.
Technical scheme of the present invention is achieved in that
A kind of production method of imitative polishing natural marble is characterized in may further comprise the steps:
1., raw ores such as ceramic sand, mud are mixed by a certain percentage through wet ball mill make slurry;
2., the processing that described slurry is carried out moulding and cloth mill base obtains being furnished with the mud base of mill base;
3., the described mud base that is furnished with mill base is placed in regular turn carry out carrying out in drying, the kiln calcination, kiln before the kiln and polish outward and edging.
Its finished product structure is various in order to make, profile is more true to nature in the natural marble of various structures, and simple to operate, easy row, above-mentioned slurry being carried out the processing method of moulding and cloth mill base can set arbitrarily as required, as can be with slurry and mill base together pack into multitube extrude cloth pulp grinder or bell jar drench in glaze machine or the slip casting machine and utilize this multitube extrude cloth pulp grinder or bell jar drench glaze machine or slip casting machine with as described in slurry and mill base be discharged into the mud base that is shaped to band entire body mill base on the bearing plate made from high-temperature refractory with mold; Also can be earlier the spray-dried tower of above-mentioned slurry to be made powder, utilize automatic brick machine that powder is pressed into the mud base again, be further to reduce its difficulty of processing this moment, can carry out biscuiting to the mud base earlier, and then use device has the multitube of mill base to extrude the cloth pulp grinder or bell jar drenches the glaze machine or slip casting machine is discharged into described mill base the mud base that is shaped on the mud base with a color paste layer.
The present invention is by utilizing the method for the slurry increase that is used for moulding being carried out the cloth mill base on production line, effectively utilize the good fluidity of mill base, the characteristic that penetrating power is strong, transitional good, make mill base can penetrate into the tiny textural effect that forms in the slurry on the similar natural marble fully, thereby make its finished product exactly like natural marble, and its lines are natural and tripping, texture good, production cost is low.And owing to the processing method of slurry being carried out moulding and cloth mill base is varied, make the structure variation more of its finished product, further strengthened its vivid effect, solved existing parian effectively in aspects such as skin texture, lines and texture and problem such as natural marble differs greatly, decorative effect is relatively poor.While had both made simple more, the easy row of its operation because the present invention utilizes existing multitube to extrude the cloth pulp grinder or equipment such as bell jar slip shower or slip casting machine carry out the cloth slurry, made its finished product profile more attractive in appearance, true to nature again.
The present invention is further illustrated below in conjunction with accompanying drawing.
