Description

A kind of removable not viscous pan production method of handle
Technical field
The present invention relates to technical field of kitchen wares, are especially a kind of removable not viscous pan production method of handle.
Background technology
A kind of production method of non-stick pan tool is disclosed on the website of State Intellectual Property Office at present, it includes following step Suddenly：Sheet alloy punching press or stretching are formed main pan body by the first step；Second step carries out smart car to the surfaces externally and internally of the main pan body Processing, forms smooth surfaces externally and internally；Third step, which immerses the main pan body after smart car in weak caustic solution, carries out ultrasound clearly It washes；4th step to after ultrasonic cleaning the main pan body inner surface and the bottom of a pan carry out blasting treatment so that table in the main pan body Roughness be 3~8 μm, the bottom of a pan roughness is 1~5 μm；The main pan body outer surface of 5th step after blasting treatment sprays Porcelain coating is placed in 600~700 DEG C of sintering curings；Non-viscous paint is sprayed in its inner surface again, it is solid to be placed in 350~400 DEG C of sintering Change forms corresponding coating.
There are disadvantages for the above this production method：
1, it is cleaned by ultrasonic since main pan body immerses in weak caustic solution, pot body surface is likely present alkalinity after cleaning, Subsequent coating process is influenced, the stability of coating is reduced
2, due to directly being sprayed after blasting treatment, the bottom of a pan is likely present certain impurity, can affect spraying effect Fruit reduces the adhesive force of coating.
3, due to will separate spray-on coating on the inside of pot appearance and pot, and the sintering temperature of the two is had any different, the pot first sprayed Appearance has carried out two-step sintering, to have a certain impact to coating.
4, separately spraying, coating atomization can be adhered to other one side, influence subsequent construction operation and performance.
Invention content
The technical problem to be solved by the present invention is to provide a kind of bottom of pot body and increase electromagnetic induction, coating using stainless iron The not viscous pan making side that the more anxious stabilization of performance, adhesive force are more preferable, handle high in machining efficiency and saving occupied space is removable Method.
The technical scheme is that providing a kind of handle having following structure removable not viscous pan making side Method：It includes the following steps：
