Cooker processing technology for preventing outer surface scale

Abstract

The invention relates to a cooker processing technology for preventing outer surface scale. The technology includes the following steps that alloy materials are stretched to form a cooker body; finish turning machining is carried out on the inner surface and the outer surface of the cleaned cooker body to obtain a smooth inner surface and a smooth outer surface; non-stick cookware coating is sprayed on the inner surface of the cooker body and is sintered; plastic powder is sprayed to the outer surface of the cooker body through an electrostatic generator in an electrostatic plastic spraying mode, the thickness of the film formed by spraying powder ranges from 30 microns to 35 microns, and the film is roasted between 180 DGE C and 220 DEG C to be solidified. Priming paint is not needed for the cooker body, the paint flowing phenomenon commonly occurring in the paint spraying process cannot occur in the electrostatic powder spraying process, environmental pollution is avoided accordingly, and high efficiency, energy conservation and emission reduction are achieved. The surface of the film formed through solidification after electrostatic powder spraying is flat and smooth, adsorption capacity is weak, if the cooker is sooted in the use process, the cooker can be scrubbed and cleaned with cleaning cloth, accumulated scale cannot be formed after long-term use, the good heat conduction effect of the cooker is further guaranteed, waste of gas sources is reduced, and the service life of the cooker is prolonged.

Description

technical field [0001] The invention relates to a kitchen utensil, in particular to a pot for cooking on a gas stove. Background technique [0002] Pots are one of the essential supplies in the kitchen. Whether it is steaming, boiling, frying, or frying, various pots conduct heat under the action of a heat source to cook raw food. Most of the existing heat sources still use fire to generate heat, such as natural gas, coal gas or original firewood or charcoal fire. When these are used as heat sources to transfer heat to the pot, the surface of the pot is often blackened. Moreover, since the outer surface of existing pots is mostly made of high-temperature paint sprayed on the outside of the main body of the deposit alloy pot, and baked and solidified at about 300°C, the formed high-temperature paint film has strong adsorption force, and it is not easy to burn the surface of the pot after it is blackened. Wipe off, when the pot is used for a period of time, black scale will f...

Problems solved by technology

Moreover, since the outer surface of existing pots is mostly made of high-temperature paint sprayed on the outside of the main body of the deposit alloy pot, and baked and solidified at about 300°C, the formed high-temperature paint film has strong adsorption force, and it is not easy to burn the surface of the pot after it is blackened. Wipe it off, when the pot is used for a period of time, black scale will form on the outside of the pot, which not only affects hygiene, but also affects the thermal conductivity of the pot

At the same time, in the process of processing the existing high-temperature paint surface pots, due to the need for relatively large air pressure, a lot of materials are often wasted in the spraying process, which further causes environmental pollution.
