Problems solved by technology

However, the organic matter of fluorine will decompose at high temperature (greater than 250°C), and the coating of the organic matter of fluorine will be gradually damaged. After the organic matter of fluorine on the inner surface of the pot is damaged, the non-stick pan will lose its non-stick function. The role of the surface of the metal pan makes the surface of the exposed metal pan less smooth and more likely to stick to food
In addition, the decomposition products of fluorine organic coating are toxic, contaminate food, and are harmful to human body.

Embodiment 1

[0017] Embodiment 1: As shown in the accompanying drawings, the ceramic non-stick pan according to the present invention includes an inner pan body 1, an outer pan body 3 and an intermediate transition layer 2, and the intermediate transition layer 2 is arranged on the inner pan body 1 and the inner pan body. Between the outer pot body 3; the inner pot body 1 contains dense capillary pores, the pore diameter of which is 0.1-100.0 microns; the composition of the inner pot body 1 is ceramic mud; the composition of the outer pot body 3 It is metal-ceramic mud, and the composition of the intermediate transition layer 2 is a mixture of the ceramic mud and metal-ceramic mud.

[0018] The intermediate transition layer 2 includes the following components, and the weight percentages of each component are: 30% of ceramic mud and 70% of cermet mud; wherein the ceramic mud is the same as that used for the inner pot body 1. The metal-ceramic mud material is the same as the metal-ceramic mu...

Embodiment 2

[0022] Embodiment 2: It is basically the same as Embodiment 1, except that the intermediate transition layer 2 includes the following components, 70% of pottery mud and 30% of cermet mud.

[0023] The pottery mud material includes the following components, and the weight percentages of each component are: 50% of granular barren material, 49.8% of pottery clay, and 0.2% of pore-forming agent; wherein the granular barren material is quartz, corundum, Mo A mixture of stone-like granular materials; the pore-forming agent is calcium carbonate.

[0024] The cermet mud material includes the following components, and the weight percentages of each component are: 30% of metal powder, 4% of granular barren material, and 66% of pottery clay; wherein the metal powder is preferably iron powder and copper powder, and the particle size is ≤200 mesh ; The granular barren material is a mixture of quartz and corundum granular materials.

Embodiment 3

[0025] Embodiment 3: It is basically the same as Embodiment 1, except that the intermediate transition layer 2 includes the following components, 50% of pottery mud and 50% of cermet mud.

[0026] The pottery mud includes the following components, and the weight percentages of each component are: 15% of granular barren material, 84.5% of pottery clay, and 0.5% of pore-forming agent; wherein the granular barren material is quartz, corundum, Mo A mixture of lithic and cordierite granular materials, the particle size of the granular barren material is ≤150 mesh; the pore-forming agent is carbon powder.

[0027] The cermet mud material includes the following components, and the weight percentages of each component are: 15% metal powder, 10% granular barren material, and 75% pottery clay; wherein the metal powder is iron powder, copper powder and other metal powder, and the particle size is ≤200 mesh; the granular barren material is a mixture of quartz, corundum, and mullite granul...

Abstract

The invention discloses a ceramic non-stick frying pan. The ceramic non-stick frying pan comprises an outer-layer pan body and an inner-layer pan body provided with dense pores, wherein an intermediate transitional layer is arranged between the outer-layer pan body and the inner-layer pan body, wherein the inner-layer pan body is made of ceramic pug; the outer-layer pan body is made of metal ceramic pug; and the intermediate transitional layer is made of a mixture of the ceramic pug and the metal ceramic pug. The ceramic non-stick frying pan has the advantages that: the ceramic non-stick frying pan has the characteristics of the ceramic pug, and high chemical stability and temperature shock resistance; the contacting mode between the surface of the pan and foods is changed from common surface contact to multi-point contact; the pores on the inner-layer pan body can adsorb and release cooking oil when the foods are cooked, an oil film is kept between the cooked foods and the pan body, so that the cooked foods are in the semi-suspending state and the non-stick function can be maintained for a ling time; and because the outer-layer pan body is made of the metal ceramic pug, the non-stick frying pan has high heat-conducting property and can effectively avoid a blow-up phenomenon caused by local overheating of the ceramic pan body.

Description

technical field [0001] The invention relates to a pan, in particular to a ceramic non-stick pan. Background technique [0002] The currently used non-stick pan is to coat a layer of fluorine organic matter on the inner surface of the metal pan, and utilize the non-wetting property of the fluorine organic matter to make it have a non-stick function. However, the organic matter of fluorine will decompose at high temperature (greater than 250°C), and the coating of the organic matter of fluorine will be gradually damaged. After the organic matter of fluorine on the inner surface of the pot is damaged, the non-stick pan will lose its non-stick function. The effect of the surface of the metal pan makes the surface of the exposed metal pan less smooth and more likely to stick to the food. In addition, the decomposed products of the fluorine organic coating are toxic, contaminate food, and are harmful to the human body. Therefore, with people's awareness of this non-stick pan, it...
