Description
Technical Field
The invention relates to the field of surface treatment of technical iron pans, in particular to a novel surface treatment process of an iron pan.
Background
With the change of consumer structures and the upgrade of consumer capabilities, the demands of consumers on cookers are higher and higher. Although the pan with the coating is not adhered to a pan, the coating is good, the Chinese style cooking habit ensures that the coating pan has short service life, the coating is unsafe to enter the dish, consumers have fear, and the pan with the coating has relatively high acceptance degree when being used as a pan for soup and frying; although the traditional iron pan with one pan for frying in the sky has no coating and is safe, the traditional iron pan has large oil smoke, uneven heating, sticking to a pan and a coke pan and serious bottom deformation, and is not suitable for an induction cooker. Because the cookware in the market has different quality and the consumption experience after being purchased for multiple times is poor, many consumers do not believe that the cookware is manufactured in China, but choose to purchase the cookware with foreign brands at a high cost for comfort, and the final result is usually only relatively good but not satisfactory.
At present, consumers have a series of requirements on higher levels such as no coating, no pan sticking, less oil smoke, shovel resistance, stir-frying and the like, so that a plurality of enterprises are in a loss, at present, the research and development of the change of cookers by a plurality of enterprises only stop at the change of appearance and the addition of enough gimmicks to promote the sale, the surface treatment process of a good novel iron pan is lacked, the exterior of the iron pan lacks a good beautiful structure, the cooker does not have a good integrally-formed die-cast beautiful embossed character, the coating structure is mostly adopted, the actual safety is general, namely, the coating is mostly harmful carcinogenic substances, in addition, the inner wall of the iron pan body lacks a good grinding process, the formation of an internal oil film of the iron pan is not facilitated, the actual environmental protection performance and the antirust performance are general,
therefore, a new surface treatment process of the iron pan is developed.

s2, polishing an iron pan, namely placing the iron pan to be processed on a base fixed in a limiting mode, enabling the inner side of the iron pan to be processed to be upward, adjusting a cross grain polishing mechanism in the iron pan, polishing the inner side of the iron pan to be processed by adopting cross grains, enabling the inner wall of the iron pan to be processed to form irregular cross grains, enabling the cross grains of the inner wall of the iron pan to be easily subjected to oil hanging, and further easily generating an oil film on the inner surface of the iron pan when the inner part of the whole iron pan body is contacted with oil, namely being environment-friendly and clean, and enabling the formed natural oil film to play a role in sanitation and rust prevention of the inner wall of the iron pan;
s3, oil liquid on the iron pan forms an oil film, the processed iron pan is clamped through clamping steel pincers and placed at the heating end of a heating device, the temperature is controlled through the heating device, 800-DEG C high-temperature bluing work is carried out, namely the iron pan is baked at high temperature, the external color of the iron pan is baked to change color, the internal black color is baked to light blue, the heating is stopped at the moment, a proper amount of vegetable oil is dipped on the inner wall and the outer wall of the pan body through an oil brush, the vegetable oil is uniformly smeared inside and outside the pan body after the bluing, the small fire heats the inside and the outside of the pan body after the vegetable oil is smeared, namely 180-DEG C internal and external cyclic heating of the pan body is carried out, and the oil film is formed inside and outside the iron pan body;
s4, performing paint baking work on the iron pan, namely sequentially performing oil removal, water washing, rust removal, water washing, surface conditioning, water washing, phosphorization, water washing and drying on the outside of the iron pan to finish the paint baking work, and then performing foil stamping decoration on the pattern or character cast part outside the iron pan through a gold sliding process of a cast iron pan;
s5, preserving the iron pan, smearing vegetable oil on the inner part and the outer part of the processed iron pan through pigskin, smearing the vegetable oil uniformly on the inner part and the outer part of the iron pan, cleaning and washing the iron pan through soft cotton cloth and clear water, hanging the iron pan at a cool and ventilated place for airing, and packaging and storing the iron pan by using oil paper after the airing is finished.
2. The surface treatment process of the novel iron pan as claimed in claim 1, which is characterized in that: the degreasing is mainly to remove mineral oil, lubricating grease, animal and vegetable oil of iron pan, for example, the grease such as hand touch during operation and transportation can seriously reduce the adhesive force of most paints and affect the drying of the paints, and also can reduce the hardness and glossiness of the coating, the greasy dirt on the workpiece can be removed by alkali solution, the main alkali is NaOH, NaHCO3 and the like, and the special degreasing powder can be purchased and then prepared into aqueous solution, and the saponification of soap.
3. The surface treatment process of the novel iron pan as claimed in claim 1, which is characterized in that: the rust removal, namely yellow rust outside an iron pan can promote corrosion products to spread under the coating, so that the coating loses shielding property and moisture impermeability, can cause early damage of the coating and metal under high-temperature and high-humidity conditions, loose yellow rust and poor adhesion, and can fall off together with the coating.
4. The surface treatment process of the novel iron pan as claimed in claim 1, which is characterized in that: the phosphorization is a central link of pretreatment before coating, a metal workpiece is treated by orthophosphate solution of manganese phosphate, zinc phosphate and cadmium phosphate, so that an insoluble phosphate protective film is formed on the surface of the workpiece, the formed phosphorization film has a compact structure with fine pores, the surface area of the workpiece is increased, the contact area of a coating can be increased, favorable mutual permeation is generated between the phosphorization film and the coating, the adhesion of an organic coating to the workpiece is greatly improved, the phosphorization film formed by phosphorization is a stable non-conductive isolation layer, the metal surface is changed from a good conductor to a poor conductor, the formation of a micro-battery is inhibited, the corrosion of the coating is effectively prevented, the common phosphorization method comprises high-temperature phosphorization (70-90 ℃), medium-temperature phosphorization (50-70 ℃) and normal-temperature phosphorization (20-30 ℃) according to the treatment temperature, and the metal surface is generally black.
