Problems solved by technology

Graphite products need to be treated on the surface and cannot be in direct contact with food. Therefore, a non-stick coating with wear resistance and high adhesion must be prepared on the surface. The general treatment method is to spray a layer of fluorine with compressed air. Resin coating or ceramic coating, and these methods will pollute the environment, and most of the coatings are oily, which will cause three hazards, and the labor hygiene environment is poor, and the gloss, hardness, and adhesion of the coating are not high.

preparation example Construction

[0055] Such as figure 1 , image 3 and Figure 4 As shown, according to a preparation method of a cooker 100 provided in some embodiments of the present invention, the cooker 100 includes a base 10 and a non-stick coating 30, the base 10 is made of graphite, and the non-stick coating 30 is attached to the inner wall of the base 10 Above, the non-stick coating 30 includes a surface layer 303, and the preparation method of the cooker 100 includes: step S10, preparing the substrate 10 with graphite; step S20, preparing the non-stick coating 30 on the inner wall surface of the substrate 10, wherein the step S20 specifically It includes: step S214, spraying powder paint on the inner wall surface of the base body 10 by electrostatic spraying method, so as to prepare the surface layer 303.

[0056] The preparation method of the cooker 100 provided by the above-mentioned embodiments of the present invention includes preparing the substrate 10 with graphite, and preparing a non-stick...

Embodiment 1

[0093] Graphite products are made by hot pressing and sintering graphite powder;

[0094] Use compressed air to remove surface dust before spraying base oil such as graphite pans and graphite plates, the air pressure is 6kg; and perform degreasing treatment to remove oil stains and impurities on the surface of the base 10. The degreasing process is 350 ° C for 15 minutes;

[0095] Sandblasting is not required before spraying, because graphite has good adsorption properties, and the sprayed primer, medium oil, PFA powder (powder coating) and the like can be well attached to the inner wall surface of the substrate 10;

[0096] Preheat the substrate to 50°C;

[0097] Before spraying, the powder is dispersed by a ball mill at a speed of 40 rpm for 60 minutes, and filtered by a filter screen. The base oil is filtered by 140 mesh, and the medium oil and powder coating are filtered by 100 mesh;

[0098] Spraying the bottom layer 301: the spraying paint is a special primer for PFA, t...

Embodiment 2

[0103] Graphite products are made by hot pressing and sintering graphite powder;

[0104] Graphite pans, graphite plates and other cooking utensils 100 use compressed air to remove surface dust before spraying the primer, and the air pressure is 8kg; and perform degreasing treatment to remove oil stains and impurities on the surface of the substrate 10. The degreasing process is 380 ° C for 10 minutes;

[0105] Sandblasting is not required before spraying, because graphite has good adsorption properties, and the sprayed primer, medium oil, PFA powder (powder coating) and the like can be well attached to the inner wall surface of the substrate 10;

[0106] Preheat the substrate to 70°C;

[0107] Pre-treatment of coatings. Before spraying, the powder is dispersed by a ball mill at a speed of 60rpm for 20 minutes, and filtered by a filter. The base oil is filtered by 160 mesh, and the middle oil and top oil are filtered by 120 mesh;

[0108] Spraying the bottom layer 301: The sp...

Abstract

The invention provides a cooking utensil and a preparation method thereof. The preparation method of the cooking utensil comprises the steps that S10, graphite is used for preparing a base body; and S20, a non-sticking coating is prepared on the inner wall face of the base body, wherein the step S20 specifically comprises S214, namely powder coating is sprayed on the inner wall face of the base body by an electrostatic spraying method to prepare a surface layer. According to the preparation method of the cooking utensil, the electrostatic spraying method is used for prepare the surface layer on the graphite base body, so that the comfort of operation during spraying is improved, the working condition is improved, and the environment is not polluted; because of the good adsorption of the graphite base body, sandblasting treatment is not required before spraying, and the manufacturing cost of the cooking utensils is reduced.

Description

technical field [0001] The invention relates to the field of kitchen utensils, and more specifically, to a cooking utensil and a preparation method thereof. Background technique [0002] Graphite has the characteristics of high thermal conductivity, fast heat transfer, uniform heating, and fuel saving. Therefore, baking pans and pots made of graphite have the characteristics of fast heating, uniform heating, food cooked from the inside out, short heating time, and pure food taste. And can lock the original nutritional advantages of food. In addition, graphite also has the characteristics of chemical stability and corrosion resistance, as well as health and environmental protection, no radioactive pollution, and high temperature resistance. Graphite is therefore particularly suitable for the preparation of a range of cookware. Graphite products need to be treated on the surface and cannot be in direct contact with food. Therefore, a non-stick coating with wear resistance an...
