The method comprises the following steps that a formed aluminum alloy strip is subjected to processes of embossing, degreasing, washing, anodic oxidizing, washing, drying, shearing and the subsequent steps. The method of the invention has the advantages that the orange-figured plate with high oxidation resistance manufactured by the special degreasing and oxidization processes has good surface quality, and is capable of eliminating the oxide film defects of red light, aging and the like, effectively removing the stain on the plate surface caused by rolling oil residue and the like, effectively enhancing the corrosion resistance and the wear resistance of an oxide film, and increasing the product quality and performance index, and fully satisfying the quality requirement of orange-figured plate with high oxidation resistance.
Description
Technical field
The present invention relates to a kind of method of manufacture of tangerine card, particularly a kind of method of manufacture of high antioxidant tangerine card.
Background technology
The refrigerator ice cabinet of being produced by the ordinary oxygen metallization processes that adopts is at present used the tangerine card; Its surface quality is unstable; Ruddiness, surface quality defect phenomenon such as aging appear easily; Simultaneous oxidation film erosion resistance, abrasion resistance are relatively poor, and the manufacturing process flow of tangerine card is longer, causes problems such as production efficiency and yield rate are low.
Summary of the invention
Goal of the invention: the objective of the invention is deficiency, the better tangerine card of a kind of oxidation-resistance method of manufacture is provided to prior art.
Technical scheme: a kind of method of manufacture of high antioxidant tangerine card, the key step of this method is following:
1) carries out degreasing after making the aluminium alloy strips embossing of moulding, in degreasing tank, add 2/3 water, add tsp, steam heating to 40 ℃～65 ℃, washing then according to the ratio of 30g/L～60g/L;
2) aluminium alloy strips after the washing carries out anodic oxidation, and the free acid concentration of oxidation trough electrolyte inside is that 100～250 g/L, aluminium ion concentration are 10～40g/L, and current density is 1.0～1.9A/dm
2, oxidation rate is that 2～9m/min, electrolyte temperature are 15 ℃～42 ℃, forming thickness to the aluminium alloy strips surface is the compactness aluminum oxide film of 5～15 μ m, washes and subsequent steps such as conventional oven dry, shearing again.
The washing of aluminium alloy strips before and after the anodic oxidation, hydraulic pressure are that 1.5～2.5bar, water ph value are 6～8, chloride ion content≤30mg/L in the water conductance≤100 μ S/cm, water.
The free alkali concentration of degreasing fluid is 40～65g/L, AL in the degreasing tank
3+Concentration is that 10～60g/L, pH value are 10～13.
Beneficial effect: advantage of the present invention is in the method for manufacture of tangerine card, to adopt special degreasing, oxidizing process; Produce the tangerine card of high antioxidant, it not only has good surface quality, and has eliminated ruddiness, sull defective such as aging; Effectively removed simultaneously the plate face stain that the residual grade of ROLLING OIL causes; Sull erosion resistance, abrasion resistance all are able to effective raising, have promoted quality product and performance index, satisfy high antioxidant tangerine card specification of quality fully.
Embodiment
Below in conjunction with specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
A kind of method of manufacture of high antioxidant tangerine card, concrete steps are following:
1) carry out degreasing after making the aluminium alloy strips embossing of moulding, in degreasing tank, add 2/3 water, add tsp according to the ratio of 30g/L～60g/L, steam heating to 40 ℃～65 ℃, the free alkali concentration of degreasing fluid is 40～65g/L, AL in the degreasing tank
3+Concentration is that 10～60g/L, pH value are 10～13, then washing.
Aluminium alloy strips is through in the skim soln of certain temperature tsp the time; Because tsp is hydrolyzed into strong basicity; With the grease generation saponification reaction on aluminium alloy strips surface, generate the StNa of solubility, thereby can guarantee the cleanliness factor of aluminium alloy strips surface degrease.
2) aluminium alloy strips after the washing carries out anodic oxidation, and the free acid concentration of oxidation trough electrolyte inside is that 100～250 g/L, aluminium ion concentration are 10～40g/L, and current density is 1.0～1.9A/dm
2, oxidation rate is that 2～9m/min, electrolyte temperature are 15 ℃～42 ℃.Aluminium alloy strips through washing places electrolytic solution through conductive rollers is charged as anode, utilizes electrolytic action, and forming thickness to the aluminium alloy strips surface is the compactness aluminum oxide film of 5～15 μ m, washes once more.
The washing of aluminium alloy strips before and after the anodic oxidation, hydraulic pressure are that 1.5～2.5bar, water ph value are 6～8, chloride ion content≤30mg/L in the water conductance≤100 μ S/cm, water.
3) subsequent steps such as the oven dry of routine, shearing.
After making high antioxidant tangerine card of the present invention, tackle its visual appearance and surface quality and check, when wherein checking surface and oil contaminant, drip 3～5 65 at aluminium foil surface
#Pairing oil uses absorbent cotton in the place's wiping of aluminium foil surface oil dripping once then, sees whether absorbent cotton has black greasy dirt or aluminium powder etc., uses the sull erosion resistance and the abrasion resistance on SRM 935a test solution testing product surface simultaneously.
