Description
Technical field
The present invention relates to a kind of making method of fictile, be specifically related to the making method of the unburned ceramic product of a kind of non-plasticity-.
Background technology
Ceramic industry is the important component part of silicate industry, and pottery is the common name of the clay-wares such as pottery, stoneware and porcelain.Pottery is produced on China long history, traditional ceramic process by Raw material processing, moulding, burn till, decorate four essential parts and form, raw materials used plastic material, non-plastic material (non-plastic raw material), the flux raw material of comprising.Fictile has the objective law of self in production process, both can apply within the specific limits its rule and reach the effect of wanting, some link that can change again wherein realizes the effect of wanting, yet, the modal problem of traditional ceramics industry---craze and transfiguration, its basic reasons is that the contraction in dry sintering process causes, although can be by optimizing shape-designing, adjust formula, revising the ways such as technical indicator processes, but this adjustment is limited, because it is almost impossible making pottery not produce contraction in dry sintering process, especially the goods of cubes or larger plane, craze and transfiguration is particularly outstanding, often yield rate is very low, cost is high, meanwhile, traditional ceramics is made must not only need to consume mass energy through firing, and also can cause environmental pollution.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the above defect, provides that a kind of operation is simple, easy to learn, the making method of energy-conserving and environment-protective, the unburned ceramic product of non-plasticity-that yield rate is high.
In order to solve the above technical problem, the making method of the unburned ceramic product of a kind of non-plasticity-of the present invention, the liquid starting material that described ceramic product adopts non-plastic raw material industrial magnesium oxide, quartz, silicon carbide and chamotte powder to add magnesium chloride, water glass and defoamer to form, with solid casting method, inject non-water-absorbing material Mold Making and form, said method comprising the steps of:
(1) raw material is prepared:
Silicon carbide, chamotte powder are fine ground to 30～60 orders, and industrial magnesium oxide, quartzy fineness are 180～250 orders, and the shared weight percent of each composition is: industrial magnesium oxide 50-60%, quartzy 20-30%, silicon carbide 5-15%, chamotte powder 5-15%, and this is A component;
It is that neutral clear water is modulated into the magnesium chloride solution that Baume gravity is 20-30 degree that magnesium chloride adds pH value, the water glass that adds the 0.2-0.5% of described magnesium chloride solution weight, stir, use the defoamer that adds the 0.5-1.5% of described magnesium chloride solution weight in first 72 hours, stir, be made into liquid starting material, this is B component;
(2) take the part by weight of A component and B component is 2:0.8-1.2, and A component is added in the B component solution preparing successively by the ascending order of proportion, after standing 2-10 minute, stirs 3-10 minute, obtains slurry, standby;
(3) gained slurry is injected in non-water-absorbing material mould with solid casting method, carry out exhaust-gas disposal, when slurry loses flowability formation thick paste, scrape off unnecessary slurry, make the smooth standard of plane;
(4) standing under natural temperature, when product strength reaches 1.5-2 Mohs' hardness, get final product the demoulding;
(5) after the demoulding, in time product is repaired to polishing, naturally dry in the shade, product is carried out to colored drawing, pigment dries and gets product.
As preferably, the method for the invention A component also comprises that fineness is 180～250 object 1-10% talcums and 1-10% calcite.
The making method of the unburned ceramic product of non-plasticity-of the present invention, mainly to being dried in existing pottery process, burning till two links implements to change, raw materials used is the non-plastic raw material in the conventional raw material of ceramic process, shrink little, not yielding, cracking, A, there is physics in B component together, chemical reaction, produce and solidify, this formula and Technology can meet the Technology requirement of the solid casting method of forming, can production traditional technology difficult relatively large product and the cubes fictile of producing, as cinerary casket, raised table, landscape basin, the larger multiple pottery technique product such as sculpture, reach traditional pottery and be difficult to the effect realizing, and whole techniques of burning till part have been removed, realized energy-conservation, environmental protection object.
Beneficial effect of the present invention: owing to having used the above technical scheme, the present invention compared with prior art has the following advantages:
1, operation is simplified existing pottery program complexity, and the method for the invention is extremely simplified, and operation is only 1/3rd of traditional technology, and operation is easy to learn, is convenient to promote;
2, energy-conserving and environment-protective, the low the method for the invention of cost are removed firing process from, save mass energy, non-environmental-pollution problem, and yield rate can reach more than 98%, effectively reduces costs;
3, the method for the invention applied widely can be made cubes fictile and relatively large product pottery technique product, has overcome traditional technology insoluble problem always in this respect, for human consumer provides how better selection.
