Surface-nonstick stainless steel product

Abstract

The invention provides a stainless steel product with a non-stick surface. The stainless steel product has a stainless steel body, at least one surface of the stainless steel body is evenly distributed with arc-shaped pits, and the surface roughness is Ra1-2μm. A sintered non-stick layer attached to the surface of the stainless steel main body, the thickness of the sintered non-stick layer is 1-5 μm. The treatment process of the stainless steel products of the present invention includes steps such as polishing, shot blasting, cleaning, spraying, and sintering. Clean the stainless steel surface to ensure the cleanliness of the stainless steel surface and avoid scale. At the same time, the invention can improve the surface strength of the stainless steel non-stick product, increase the adhesion between the surface of the stainless steel non-stick product and the non-stick layer, and enhance the surface corrosion resistance. Highlight the metallic texture of the surface. Extend the life of stainless steel non-stick products.

Description

technical field [0001] The invention relates to a stainless steel product with a non-stick surface, and is especially suitable for the non-stick surface treatment of stainless steel products such as stainless steel decorative materials, stainless steel anti-theft doors and stainless steel kitchen supplies. Background technique [0002] At present, stainless steel products have been widely used in the fields of stainless steel decorative materials, stainless steel anti-theft doors and stainless steel kitchen supplies. [0003] The surface treatment methods of existing stainless steel cookware include: polishing, sanding, and surface spraying non-stick layer. When using cookware with stainless steel polishing and sanding surface treatment to process food, sticking or burning will occur. The stainless steel cooking utensils with non-stick layer treatment process on the surface can avoid the phenomenon of sticking and burning when the cooking utensils are processing food, and b...

Problems solved by technology

However, some cookers with a non-stick layer are currently on the market. When this type of cooker is processing a non-stick layer, the surface of the cooker body is sprayed with emery to form irregular pits on the surface of the cooker body, and then the surface of the cooker body is sprayed on the cooker body by washing with water. Wash off the emery on the surface, and finally, spray the non-stick material solution, and make the non-stick material solution adhere to the cooker body after high-temperature baking. Using this production process can reduce food sticking to the pan to a certain extent. Or sticky pot phenomenon, but there are following deficiencies in existing technology: 1, after the cooker body surface is processed by corundum, the emery grit attached to the cooker body surface cannot be thoroughly cleaned by water, and cleanness cannot be achieved. 2. As we all know, water contains a lot of mineral components, especially calcium and magnesium. Clean the cooker body with water to make the surface of the cooker body easy In this way, when the non-stick layer is sprayed, the firmness of the adhesion between the non-stick layer and the cookware body is affected; 3. The pits on the surface of the stainless steel cookware processed according to the existing technology are different in depth and irregular in shape, so the sprayed non-stick The layer needs to be relatively thick, even if a transparent non-stick layer is used, the existence of the coating will be clearly seen, so the surface has lost the stainless steel metal texture, which affects the overall appearance of the cooker

The surface treatment of the existing stainless steel anti-theft doors mainly includes two processes of polishing and wire drawing. The main disadvantage is that the anti-pollution property is not good, such as sweat stains, dust pollution, it is not easy to remove, and it is easy to be scratched by hard objects and difficult to repair.
