Detailed description of the invention
embodiment one:
Shown in Figure 1, the stainless steel body 1 described in the present embodiment is frying pan shape, and the inner surface of described stainless steel body 1 has evenly been covered with circular arc pit, and the surface roughness of stainless steel body 1 inner surface is Ra1 ~ 2 μm.
Stainless steel product described in the present embodiment can be the body that single stainless steel material is made, and also can be superficial layer is stainless steel material, and sandwich layer is the pot body that the composite of aluminium or copper is made.
The present embodiment to the processing of stainless steel body, through following steps:
Polishing → shot-peening → cleaning →, wherein:
(1) polishing: first carry out mirror finish process to the inner surface of stainless steel body 1, makes the roughness of stainless steel body internal surface between Ra0.05 ~ 1 μm.By the mirror finish process to stainless steel body 1 inner surface, oxide layer and other impurity on surface can be removed, ensure the cleannes on its surface.
(2) shot-peening: adopt the mirror finish face of bead to stainless steel body 1 to carry out shot-peening, make a pot inner surface be covered with uniform circular arc pit, make stainless steel body internal surface roughness be Ra1 ~ 2 μm.Usual above-mentioned bead granularity is that 60 ~ 160 orders are more suitable.Adopt 100 order beades to carry out bead in the present embodiment, after shot-peening, the inside surface roughness of stainless steel body 1 is Ra1.3 μm, makes the uniform depth of the circular arc pit of stainless steel body surface consistent, the metal-like of outstanding stainless steel surfaces.
Due to technique employing is in the past that corundum carries out surface roughening to stainless-steel pan body, and corundum shape is sharp-pointed and irregular, after sandblasting, makes stainless-steel pan surface form deep mixed unevenness.When cleaning, cannot thoroughly be removed by the microparticle impurity in unevenness clean, after making follow-up spraying non-adhesive material solution, antistick layer cannot be fully bonding with stainless-steel pan surface, causes the easy layering of antistick layer to come off.And the inner surface of stainless steel body 1 can be made to obtain certain roughness by blasting process, and then body of stainless steel 1 inner surface can be made to be strengthened, thus the mechanical performance of stainless-steel pan can be improved, effectively improve the fatigue resistance of stainless-steel pan.Further, because bead surface uniform is smooth, when carrying out bead, damage can not be caused to stainless steel body 1 surface, stainless-steel pan surface metal texture can not be destroyed.And the circular arc pit that the cup depth making it be formed on the surface is identical, be conducive to thoroughly cleaning stainless steel body 1 surface in follow-up matting, thus the cleannes on stainless steel body 1 surface can be ensured, be conducive to increasing the adhesive force between stainless steel body 1 and coating and adhesion, make antistick layer 2 bonding with stainless steel body 1 more firm, extend the durability of antistick layer.
(3) clean: the stainless steel body 1 through bead is cleaned as cleaning agent with the volatile organic solvent of heating, to remove the dirt on surface, not only available energy decomposes some attachments oil in its surface, ensure the cleaning of cooker surface, after cleaning also can be made to complete, organic solvent volatilizees fast simultaneously, make its surperficial non flouling behaviour, improve antistick layer 2 and the adhesive strength of stainless steel body 1, ensure the attractive in appearance of pot surface.The organic solvent adopted in the present embodiment is trichloro-ethylene, concrete cleaning is divided into three steps: the first step is for slightly to wash, stainless-steel pan body to be cleaned is immersed in the trichloro-ethylene of 50 ~ 70 DEG C, start the supersonic generator of 28KHz simultaneously, coordinate by organic solvent and ultrasonic wave the cleaning carried out 2 minutes.Second step is fine purifiation, being immersed by the stainless steel body through slightly washing in the trichloro-ethylene of 60 ~ 70 DEG C, starting the supersonic generator of 68KHz simultaneously, continues cleaning 2 minutes.3rd step is steam drying, utilizes the trichloroethylene steam of 80 ~ 90 DEG C to purge 2 minutes, the trichloro-ethylene sticked on stainless steel body is volatilized clean.
Do not have treated hard water to clean stainless steel cooker surface because existing technique adopts, after cleaning completes, stainless-steel pan surface easily produces incrustation scale, thus affects the adhesive strength of antistick layer and stainless-steel pan body.And in the present embodiment, organic solvent is utilized to clean stainless-steel pan body, because organic solvent has larger volatility, like this after cleaning completes, the cleaning fluid remaining in stainless-steel pan body surface can volatilize rapidly and can not produce scale formation, thus effectively ensures the surface cleanness of stainless steel body.
Certainly the volatile solvent of the chemical properties similars such as trichloroethanes also can be adopted as cleaning agent, but due to stainless steel cooker be metal material, trichloro-ethylene has stronger degreasing metal effect, and therefore, the embodiment of the present embodiment is preferred embodiment.
In the present embodiment; for reducing cleaning cost and improving cleaning efficiency; described cleaning is cleaned in supersonic wave cleaning machine; because prior art adopts giant to clean, easily leave cleaning dead angle and be subject to artifact impact, making cleaning performance not reach technical requirement; and this technique adopts supersonic wave cleaning machine to clean; this not only can be avoided artifact on the impact of cleaning performance, and also can not leave cleaning dead angle, the cleaning of protection stainless steel body.Supersonic wave cleaning machine significantly improves the cleaning quality of product, makes product quality more reliable.
