Problems solved by technology

However, there are also some disadvantages. For example, the thermal shock resistance test results of general ceramic cookers are all below "450°C put into 20°C water without cracking once". Rapid cooling and rapid heating with large temperature difference during use may cause the cooker Cracking; some cooking utensils with a poor degree of porcelain have high water absorption and are easy to absorb odors. Their strength is poor and they are easy to be damaged during use.

Embodiment

[0032] (1) Blank preparation

[0033] Get 45 parts by weight of spodumene, 38 parts by weight of kaolin, 8 parts by weight of petalite, 6 parts by weight of waste porcelain, and 2 parts by weight of bentonite as raw materials for blank;

[0034] ——The above-mentioned spodumene was calcined at a temperature of 1240°C for 15 hours; the above-mentioned kaolin came from two different producing areas of Fujian Longyan and Guizhou, of which Fujian Longyan kaolin and Guizhou kaolin each accounted for 50% of the kaolin consumption; the above-mentioned waste Porcelain refers to the scrapped porcelain after firing, which is hammered into pieces;

[0035] After mixing the above raw materials, add water to carry out wet ball milling. The raw materials after ball milling are passed through a 200-mesh sieve after iron removal by the iron remover. The mud machine is used for mud refining, and a billet with a mass moisture content of 22% is prepared for use;

[0036] (2) Glaze preparation ...

Abstract

The invention discloses a manufacturing method of a ceramic cooker with high thermal shock resistance. The manufacturing method is characterized by including the following production steps of 1, blank preparation; 2, glaze preparation; 3, forming and fettling; 4, biscuiting; 5, glazing; 6, firing. The manufactured ceramic cooker with high thermal shock resistance is high in percent of pass, regular in appearance, dense in glaze layer and high in strength, and the product is not broken after being put in water at the temperature of 20 DEG C for heat exchange once when the thermal shock resistance reaches 600 DEG C.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a ceramic cooker with high thermal shock resistance and a preparation method thereof. Background technique [0002] Ceramic cooking utensils (such as soup pots, woks, etc.) are hygienic, practical, easy to clean, and have good heat storage performance. However, there are also some disadvantages. For example, the thermal shock resistance test results of general ceramic cookers are all below "450°C put into 20°C water without cracking once". Rapid cooling and rapid heating with large temperature difference during use may cause the cooker Cracking; some cooking utensils with a poor degree of porcelain have a high water absorption rate and are easy to absorb odors. Their strength is poor and they are easy to be damaged during use. Through technological innovation, seeking technological breakthroughs in terms of raw material formula and production technology, the ceramic heat-resistant cookin...
