Problems solved by technology

[0007] The above ceramic cooking utensils are suitable for cooking methods such as boiling, stewing, steaming, etc. Under the protection of a large amount of soup, these cooking methods will heat the pot more evenly and the temperature difference will be small, so the requirements for the thermal performance of the pot are relatively loose. If frying, frying, deep-frying and other heating methods with high temperature, rapid fire, and large temperature difference are required, the existing ceramic cooker is prone to cracking defects. If the size of the product is large, it will be more difficult to produce and process.

Abstract

The invention provides a super heat resistant ceramic wok and a manufacturing method thereof. The ceramic wok adopts the main raw materials of spodumene, quartz, kaolin, talc and waste ceramic slag, and a high-performance polyacrylamide dispersing agent is also added, thereby the dispersity and the stability of ceramic slurry are improved. Meanwhile, a small amount of niobium oxide is doped so asto restrain material grain growth and reduce an expansion coefficient and ensure that a product has small cracking and deformation and excellent thermal shock resistance. The super heat resistant ceramic wok can be suitable for quick-fry and cannot crack with intense fire and dry burning. The super heat resistant ceramic wok can also resist heat exchange at 650-20 DEG C without cracking, be not easy to have wok sticking and cannot be oxidized or corroded without toxicity and harm. The lead and cadmium dissolution rate of the super heat resistant ceramic wok is zero, and a radio-nuclide limit also conforms to the national standard.

Description

technical field [0001] The invention belongs to the technical field of inorganic ceramic materials, and in particular relates to a super heat-resistant ceramic frying pan and a manufacturing method thereof. This product is suitable for processing dishes in various ways such as frying, frying, deep-frying, stewing, boiling, and steaming. Background technique [0002] Ceramic cooking utensils have unique advantages such as good heat storage, environmental protection, and corrosion resistance. Various ceramic cooking utensils have appeared in common people's homes and catering industries, competing with traditional metal cooking utensils. [0003] In the 1990s, my country began to research and develop ceramic pots and utensils made of new low-expansion materials. New products were put on the market and were well received by consumers. The national light industry standard "QB / T2580-2002 Fine Ceramic Cooker" stipulates the performance requirements of this type of product, and th...
