A kind of non-stick pan
Technical field
The invention belongs to cooker technical fields, more particularly, to a kind of non-stick pan.
Background technology
The spraying pot embryo of cookware industry, which is substantially, at present is increased using surface sand-blasting or Shot Blasting technique in pot ontology The roughness on surface promotes the adhesive force of surface non-sticking lining with this.
Sandblasting and ball blast are all to increase the roughness of pot body internal surface by making pot body internal surface deform upon, figure 4 be the pot ontology partial cutaway schematic after blasting treatment, and Fig. 5 is the pot ontology part section signal after blasting treatment Figure, although can be seen that pot body internal surface from Fig. 4 and Fig. 5 produces apparent recess portion and protrusion under the action of deformation, But if when non-sticking lining is painted on pot body internal surface, the adhesive force between non-sticking lining and pot body internal surface It is not sufficient to ensure that coating is firmly attached to a pot body internal surface, coating is easily de- from pot body internal surface under the shock of hard object It falls, so all can first spray one layer of base oil or middle oil in pot body internal surface to promote non-sticking lining before spraying non-sticking lining Adhesive force, this adds increased the production costs of pot body.
Invention content
The present invention for overcome the deficiencies in the prior art, provides a kind of non-stick pan of non-sticking lining strong adhesive force.
To achieve the goals above, the present invention uses following technical scheme:A kind of non-stick pan, including:Pot ontology, the pot Body internal surface forms multiple microcellular structures by laser scanning.
Due to scanning to form multiple microcellular structures in pot body internal surface using laser, these microcellular structures have the present invention The bore of very little and longer hole depth, the micropore of these slim-lined constructions can be distributed in extremely intensive state in pot ontology On surface;When non-sticking lining is sprayed on pot body internal surface, substantial portion of coating can flow into micropore, so be filled in Coating in the microcellular structure of these dense distributions can securely be grabbed as antenna or tree root to be attached on the inner wall of micropore, So that the adhesive force of entire non-sticking lining greatly promotes;And without still further spray base oil or middle oil promoted non-sticking lining and Adhesive force between pot body, non-sticking lining can be painted on a pot body internal surface, not only save production cost, simplify work Skill step, it is more environmentally-friendly energy saving;
In addition we can just can control the arrangement mode and shape of microcellular structure by controlling the running orbit of laser in advance, with The rough surface that traditional ball blast or technique of blowing sand are formed is compared, we can rationally arrange shape, quantity and the spacing of micropore;Than Such as by microcellular structure be designed to it is cellular or it is round it is rectangular be distributed in pot body internal surface, the micropore of this ordered arrangement Structure also ensures that pot body internal surface has stronger intensity, in turn while greatly increasing pot body internal surface and accumulating It effectively prevents microporous layers to deform, further improves non-sticking lining adhesive force;
Furthermore pot body internal surface, which is irradiated with a laser region, can occur quick localized hyperthermia, micropore side wall by after fast heating again It is quickly cooled down, is equivalent to and quenching treatment is carried out to micropore surface;The especially intake section of microcellular structure, with atmosphere area Bigger, and then its cooling velocity is faster, i.e. the quenching effect at the position is more preferable, and hardness higher further improves microporous layers Overall stability, even densely arranged multiple micropores, the integral strength of microporous layers is unaffected, is subsequently using process In, coating, which will not be knocked, to fall off, and enhances the scratch resistant performance of non-sticking lining, extends the durability of non-sticking lining.
