Abstract
The invention discloses low-temperature heat-resistant ceramic and a production process thereof. The low-temperature heat-resistant ceramic is prepared from the following raw materials in percentage by mass: 36%-42% of lepidolite, 24%-30% of aluminum oxide, 30%-32% of Longyan kaolin and 2%-4% of bentonite. The production process of the low-temperature heat-resistant ceramic comprises the following steps: pre-pulverizing the raw materials, then using a ball mill to perform wet-process ball milling, magnetically removing iron impurities after screening, molding, fettling and performing biscuit firing; then, performing color painting and spraying bright glaze to perform glaze firing, packaging and warehousing to obtain the low-temperature heat-resistant ceramic. The production process disclosed by the invention adopts the bright glaze, so that the produced low-temperature heat-resistant ceramic has good quality, bright color and luster and stable performances; and moreover, the sintering temperature is low, a great deal of heat is saved, and thus, the energy consumption can be lowered by 30%, not only can the fuel consumption and the fuel cost be lowered, but also great effect can be provided for energy conservation and emission reduction.
Description
Technical field
The present invention relates to ceramic product technical field, specifically a kind of low temperature thermal pottery and production technique thereof.
Background technology
Refractory ceramics is the important component part of special cermacis, sometimes also as the integral part of high-temperature refractory.Can be used as high-temperature structural material, for many fields such as aerospace, nuclear power, electronic technology, machinery, chemical industry, metallurgy, be the indispensable high temperature engineering materials of modern science and technology, various in style, purposes is very extensive.
Because traditional high temperature ceramic material composition is single, there is obvious deficiency in nature, and high temperature ceramic material exists processing difficulties, heat-shock resistance is poor, not easily carry out boning etc. shortcoming, therefore industry begins one's study novel fire resistant stupalith and low temperature thermal material.This low temperature thermal material is obtained under lower high temperature, but but with its distinctive structure and performance, has resistant to elevated temperatures performance, and therefore low temperature thermal material has very large market outlook, also has very important meaning for field of new.
Summary of the invention
The object of the present invention is to provide a kind of preparation temperature low and the low temperature thermal of superior performance pottery and production technique thereof, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A low temperature thermal pottery, is made up of the raw material of following mass percent: lithionite 36% ~ 42%, aluminum oxide 24% ~ 30%, Longyan kaolin 30% ~ 32%, wilkinite 2% ~ 4%.
A production technique for low temperature thermal pottery, concrete steps are as follows: Longyan kaolin and wilkinite are crushed to the particulate state that diameter is less than 6mm by (1) respectively; (2) raw material lithionite, aluminum oxide, Longyan kaolin and bentonite clay particle is taken according to mass percent; (3) raw material is put into ball mill and is added clear water and grind 25 ~ 30h, and is screened by 220 ~ 300 mesh sieves; (4) magnetic separation is carried out, to remove iron contamination contained in mud raw material; (5) mud raw material is carried out filter-press dehydration, after carry out vacuum pugging and become mud bar, water ratio is less than 22%; (6) mud bar is carried out shaping, repaired biscuit, and burn 800 DEG C, about 4h; (8) after cooling, can under glazed be carried out, execute spray light glaze, at the temperature of 1150 ~ 1200 DEG C, continue glaze firing 8 ~ 10h; (9) also the product after glaze firing can be carried out applique baking, packaging and warehouse-in.
Compared with prior art, the invention has the beneficial effects as follows: production technique of the present invention uses bright glaze, the good product quality produced, bright in color, stable performance; And firing temperature is low, save a large amount of heat energy, therefore energy consumption can reduce by 30%, not only reduces fuel consumption and fuel cost, and has significant role for energy-saving and emission-reduction.
