Abstract

The invention relates to a method for covering the surface of food ware with a lyophobic macromolecule metal composite skin film. The method comprises the following steps that a, preparation is made,and the treated food ware, a specific amount of polytetrafluoroethylene solution and a specific amount of aluminum-base intermetallic compound powder are provided; b, stirring and mixing are carried out, and the polytetrafluoroethylene solution and the aluminum-base intermetallic compound powder are stirred and mixed to form spraying suspension liquid; c, spraying is carried out, the spraying suspension liquid is sprayed to the surface of the food ware, and thus at least one coating is formed on the surface of the food ware; and d, forming and curing are carried out, and the coating of the food ware is heated and cured to form the lyophobic macromolecule metal composite skin film. According to the method for covering the surface of food ware with the lyophobic macromolecule metal compositeskin film, the bearing surface of the food ware has multiple characteristics of having high hydrophobicity, high viscosity resisting performance, better surface abrasion resisting ability and the like.

Description

technical field

[0001] The present invention relates to a method for covering the surface of food utensils with a hydrophobic polymer metal composite film, in particular to a food utensil surface that can effectively improve the high hydrophobicity, high anti-sticking and excellent surface wear resistance of food utensils. processing technology. Background technique

[0002] PTFE coatings have been widely used in various food utensils, such as: cooking pots, frying pans, hamburger steak grills, pans, oven trays, baking trays, toast boxes, various pastry molds, pastry Food utensils such as molds, pie plates, pie plates, and food knives. Specifically, the polytetrafluoroethylene coating is directly sprayed on the bearing surface of the food utensils (such as the inner surface and bottom surface of the frame used to carry food; or the two knife faces of food knives), so that the surface of the food utensils forms a Non-stick layer, this method can make the surface of food ute...

Embodiment Construction

[0035] The present invention will be further described below in conjunction with specific examples.

[0036] Refer to attached Figure 1~5 , this embodiment includes the following steps:

[0037] 1. Material preparation

[0038] (a) Place the prepared food utensils 10 (the food utensils 10 may be made of metal plates such as aluminum-coated steel plates or stainless steel) in an oven at 300-450°C and bake at high temperature for about 10-30 minutes to Oil stains on the surface 11 of the food utensil 10 are removed. Then, sandblasting is carried out, food utensils 10 are placed in a sandblasting machine, sandblasting raw materials are loaded into the sandblasting machine, and the sandblasting air pressure is 2 ~ 5kg / cm 2 , sandblasting the surface 11 of the food utensil 10, so that the average roughness value of the surface 11 of the food utensil 10 is between 2 and 5 μm, so that the hydrophobic polymer / metal composite film 30 is easier to form and solidify on the food utens...
