Problems solved by technology

However, if the conventional spraying method is used to directly apply the non-stick coating on the heat-resistant ceramics to produce ceramic non-stick containers, due to the poor adhesion between the smooth porcelain surface and the non-stick coating, the non-stick coating is not only easy to fall off, And the non-stick coating that has not been sintered during use is easy to penetrate into the food, which is not conducive to health
On the other hand, due to the different chemical composition, mineral composition and physical properties of heat-resistant ceramics and ordinary ceramics, the technical problems to be solved in the production process are not the same, and in the construction of non-stick coatings and cold treatment of non-stick coatings It is also different, using the production process of conventional ceramic non-stick containers cannot produce qualified heat-resistant ceramic non-stick containers

Embodiment Construction

[0028] The present invention will be described in detail below through examples.

[0029] Add cordierite to ordinary ceramic mud and mix evenly, the addition amount is 30% of the total weight of the mud, and heat-resistant ceramic mud is obtained; the earthy pot-shaped green body is made by rolling forming method; the earthy pot-shaped green body is made The body is repaired through a combination of mechanical trimming, manual trimming, and water washing; and partial glazing is performed on the outer surface of the earthy pot-shaped body; the body after partial glazing is placed in a gas tunnel kiln for firing. The temperature is 1250°C, the firing time is 9 hours, and the atmosphere is first oxidized and then reduced during firing; the inner cavity of the product is sandblasted and roughened with a mechanical sandblasting machine, and the surface of the product is dedusted with an air gun, and then the product is put into Dehumidification in the drying furnace, the temperatur...

Abstract

The invention discloses a process for producing heat-resistant ceramic non-stick containers. The process comprises the following steps: ceramic paste preparation, molding, trimming, local glazing, burning, coarsening, purification, dehumidification, spray-coating, drying, sintering and rapid cold treatment. The produced heat-resistant ceramic container with non-stick coating can be used for food cooking in a microwave oven or over an open fire. The food is not stuck to the container, so that the container is easy to clean. Additionally, the container has the advantages of good bonding property of non-stick coating, high hardness, good wearability, high qualified rate and good durability.

Description

technical field [0001] The invention relates to a production process of a heat-resistant ceramic non-stick container. Background technique [0002] Cooking and stewing food in ceramic containers such as casserole and clay pot is one of the cooking methods in my country, and has a long history. Although various metal products with dazzling and novel decorations have appeared on the market so far, ceramic heat-resistant containers are still popular because of their wear-resistant ceramic materials and stable chemical properties, and will not be mixed with harmful ingredients to affect the nutritional value and taste of food. of favor. [0003] In recent years, in order to solve the problem of food sticking to the pan during cooking, ceramic non-stick containers have also been developed and produced. However, ordinary ceramic non-stick containers are prone to bursting at high temperatures and cannot be used on open flame stoves. [0004] Therefore, there is a need for a heat-...
