The invention relates to a surface treatment method of an aluminum pot, which is characterized in that the surface of the aluminum pot is impacted by coarse silicon steel grit, steel balls and steel wire particles under high pressure through a nozzle, so that the surface generates irregular and uneven rough surfaces with different depths; using sulfuric acid, oxalic acid or mixed acid as hard anodic oxide coating treatment; spraying turbid liquid fluorine resin on the uneven surface of the coating; drying and forming after drying; the aluminum pot has good non-stick property, avoids scorching, saves oil, and has the advantages of fast heating, hardness, durability and easy cleaning.
Description
The present invention relates to a kind of method for surface treatment of aluminium pot, it belongs to the improvement of aluminum pot manufacturing process.
At present, in family kitchen aluminium matter pot light weight, conduct heat soon, use aluminum pot so fry in shallow oil, fry, boil, explode, stew etc. more.Factory's manufacturing aluminum pot has two kinds of methods to the processing on its surface, and the one, iron not dragon is handled, and impacts the surface uneven, that thickness is uneven in aluminium pot surface earlier, adheres to one deck fluoroplast again; Because the shrinkage pool of pot surface impacts is shallow and little, the fluoroplast layer easily comes off, and service life is short.Another kind is to take the hard anodizing epithelium to handle, adopt blasting craft earlier, make aluminium pot surface form uneven, deep mixed shrinkage pool, use sulfuric acid, oxalic acid or mixed acid with direct current, alternating current-direct current electrolysis mode again, make aluminium pot surface generate the hard oxide scale film of one deck, its shortcoming is the non-stick cooker poor performance, is burned easily, burning foods, and unfavorable cleaning.
The objective of the invention is to provide a kind of perfect method for surface treatment of aluminium pot, the non-stick cooker performance of its existing fluoroplast has the hard wear resistant of hard anodizing epithelium, durable advantage again.
The object of the present invention is achieved like this: its concrete process is:
Blasting treatment 1: adopt thick silicon steel sand or steel ball or clipped wire or three to mix, and penetrate on the surface of aluminum pot 6, make its generation diameter, depth difference, uneven and shrinkage pool 61 surfaces that thickness is uneven with impacting with high pressure is quick-fried;
The hard anodizing epithelium handles 2: with sulfuric acid, oxalic acid or mixed acid, with direct current or alternating current-direct current electrolysis, make the surface generate the porous hardening oxidation epithelium 7 that evenly adheres on aluminum pot shrinkage pool 61 surfaces;
Not plain process of resin 3: be sprayed on the surface 9 of oxide scale film 7 in conjunction with the different floating state suspension fluoroplast 8 of number with various;
Heating, drying 4: after fluoroplast 8 dryings of aluminum pot, put into the stove heating, drying, make particle dissolving each other mutually in conjunction with and setting and hardening;
Moulding 5.
On aluminum pot 6 rough surperficial 9, adhere to one deck hard anodizing epithelium 7, and adherence one deck fluoroplast 8 on the oxide scale film surface.Blasting treatment 1 is with 5～15kg/cm
2High pressure nozzle spray or with quick-fried steel sand, steel ball or the clipped wire penetrated of the centrifugal impact of air blast fin in aluminium pot surface, form the shrinkage pool of about 0.2～1.5m/m diameter, 30～70 μ m depths.The acid strength that anodic oxide coating 7 is handled is about 130g/1～250g/1, and the voltage of electrolysis is 25～100V, 2～5A/dm
2High current density, temperature is about 0～25 ℃, is about 30～50 μ m and generate leather film thickness.Fluoroplast 8 heating, dryings are first with 120 ℃ of left and right sides temperature, after about 10 minutes, transfer to 300～450 ℃ of temperature again and are the best through about 5～10 minutes.
Because it is adopt such scheme, product of the present invention has the non-stick cooker characteristic, sturdy and durable, wear-resisting, heating is quick, fuel-efficient, easy cleaning, long service life simultaneously.
The present invention is described in more detail below by accompanying drawing and embodiment.
Fig. 1 is a manufacture method flow chart of the present invention.
Fig. 2 is an aluminum pot schematic diagram of the present invention.
Fig. 3 is an aluminium pot surface structure cut-away view of the present invention.
Fig. 4 is known hard anodizing epithelium moulding aluminum pot structure cut-away view.
Fig. 5 is a not dragon processing aluminium pot surface structure cut-away view of known iron.
Among the figure: 1 blasting treatment, 2 hard anodizing epitheliums are handled, the processing of 3 fluoroplasts, 4 heating, dryings, 5 moulding, 6 aluminum pots, 61 shrinkage pools, 7 oxide scale films, 8 fluoroplasts, 9 surfaces, 91 fluoroplasts, 92 oxide scale films.
Shown in Fig. 1～3; The fabrication schedule of the embodiment of the invention is as follows:
1. blasting treatment 1: for improving the adherence of fluoroplast, select thick silicon steel sand for use, steel ball and the clipped wire with angle of keenness mix, with 5～15kg/cm
2Powerful compressed air, utilize nozzle ejection (or with the powerful centrifugal cutter of the air blast fin that runs up), impact quick-fried penetrating on the surface 9 of aluminum pot 6, make its generation be mixed with three kinds of vestiges and about 0.2～1.5m/m diameter, 30～70 μ m depth differences, the shrinkage pool 61 uneven, that thickness is uneven, shape is mixed and disorderly, surface also can select for use silicon steel sand or steel ball or clipped wire to impact quick-fried penetrating certainly separately.
2. the hard anodizing epithelium handles 2: on aluminum pot 6 shrinkage pools 61 surfaces is sulfuric acid, oxalic acid or the mixed acid of 130g/l～250g/l again with concentration, with direct current or combined-voltage is 25～100V, the high current density of 2～5A/dm, under about 0～25 ℃ of temperature, give electrolysis, make to generate thickness on shrinkage pool 61 surfaces and be about uniform hardening oxidation epithelium 7 of adhering to of 30～50 μ m.
3. fluoroplast processing 3: various in conjunction with the number difference with 0.2～0.5 μ m particulate, be sprayed at as the floating state suspension fluoroplast of homogeneous polymerization fluoroplasts such as PTEE on the surface of the porous hardening oxidation epithelium 7 that shrinkage pool 61 adheres to, make fluoroplast 8 can be impregnated into the inside, trough slit of thickness inequality fully, adherence is on oxide scale film 7 surfaces soundly.
4. heating, drying 4: put into 300 ℃～400 ℃ even can reach 450 ℃ stove and heat after fluoroplast 8 dryings, make particle dissolve combination and setting and hardening mutually, reach rigid surface very anti-corrosion, that release is splendid, wherein the heating if with 120 ℃ of left and right sides temperature after about 10 minutes, transfer to 300 ℃～450 ℃ temperature again, 5～10 minutes effect is better.
5. moulding 5: after adopting above-mentioned technical process moulding, make and be attached with 7 layers of oxide scale films on aluminum pot 6 surfaces successively, reach 8 layers of the most surperficial fluoroplasts.
