Description
Technical field
The present invention relates to a kind of metal part surface treatment process, relate in particular to a kind of surface treatment method that is used for water tap; Belong to the metal material surface processing technology field.
Background technology
Water tap is extensive use of in daily life, existing water tap is generally metal faucet, employing metallic substance making water tap mainly is that the body part of water tap adopts casting processing such as copper product, stainless material to form component such as the spool of packing into then, valve rod, handle.The main body of existing water tap is formed by the casting of brass, bronze (or copper alloy), after the grinding and polishing moulding, again through electroplating or spraying paint etc. and other surface treatments.The electroplating surface of water tap is handled zinc-plated, titanizing, chromium plating, nickel plating etc.Wherein coated metal (as zinc, chromium etc.) is done anode, is oxidized to positively charged ion and enters electroplate liquid; Water tap to be plated is done negative electrode, and the positively charged ion of coated metal is reduced formation coating in the metallic surface.Adopt electro-plating method to be used for the surface treatment of water tap, the faucet surface color is single, and epidermis comes off easily, and after use for some time, surperficial scratch is obvious.And adopt method for paint spraying to be used for the surface treatment of water tap, and the water tap product color is beautiful inadequately, and the epidermis lacquer comes off easily, and erosion resistance is relatively poor.
Summary of the invention
The objective of the invention is at the existing in prior technology defective, provide a kind of thermotolerance, wear resistance, erosion resistance and rich color to be used for the surface treatment method of water tap.
Above-mentioned technical purpose of the present invention is implemented by the following technical programs: a kind of surface treatment method that is used for water tap, and this method may further comprise the steps:
A, polishing: select aluminum alloy materials to make the blank of water tap or water tap parts, blank is polished, the surfaceness of polishing back blank is 0.8～0.01 micron of Ra;
B, sandblast: adopting sandblast machine is that power is ejected into material spray through the blank surface after the steps A polishing with pressurized air;
C, anodic oxidation: with placing acid electrolyte as anode through the blank after the sandblast among the step B, be 0 ℃～50 ℃ in temperature, current density is 0.1Adm
-2～4.0Adm
-2, voltage is that blank carries out painted sealing through after the anodic oxidation after carrying out anodic oxidation 60～120min under the condition of 0～100V.
The water tap parts blank that aluminum alloy materials is made among the present invention comprises parts blanks such as tap valve body body, influent-effluent base, handle, and the purpose of polishing is in order to make aluminium alloy blank surface even, smooth.Can adopt polishing wheel and abrasive grain that processing is modified on aluminium alloy blank surface.Polishing wheel generally forms with the folded system of multilayer canvas, felt or leather, and both sides clamp with circular metal plate, the rumbling compound that its wheel rim coating is formed by uniform mixing such as micron power and greases.During polishing, the polishing wheel of high speed rotating is pressed to blank, makes abrasive material produce roll extrusion and micro cutting to workpiece surface, thereby obtain the finished surface of light, surfaceness generally can reach 0.8～0.01 micron of Ra, and as preferably, surfaceness generally can reach 0.63～0.01 micron of Ra.In the sandblast process, material spray is to the impact and the shear action on the blank surface of the blank of aluminium alloy water tap or aluminium alloy water tap parts, make the surface of blank obtain certain degree of cleaning and different roughness, the mechanical property on blank surface is improved, thereby improved the fatigue resistance of blank, can produce evenly trickle male and fomale(M﹠F) on the blank surface in addition, colouring matter is stored, increased the sticking power of colouring matter, and the blank surface has the sensation of frosted.During anodic oxidation, the variation of processing parameter has very big influence to the growth and the film performance of oxide film.As improving anodic current density, oxide film generates very fast.But current density is too high, the local temperature on blank surface is too high, the dissolving of promote the oxidation film, generate the low upper layer of wear resistance, the hardness of oxide film descends on the contrary, painted closing process of the present invention in addition is common technology in the existing anode oxidation process, and the organic toner that adopts in the coloring process is common organic toner.The blank of selecting aluminum alloy materials to make water tap or water tap parts can form the oxide film with thermotolerance, wear resistance, erosion resistance and easy coloring and bright-colored difficult drop-off through polishing, sandblast and anodic oxidation at water tap or water tap parts surface.
At the above-mentioned surface treatment method that is used for water tap, the aluminum alloy materials described in the steps A is a kind of in 6061 aluminium alloys, 6063 aluminium alloys, 6066 aluminium alloys, 6070 aluminium alloys, 6082 aluminium alloys.As preferably, described aluminum alloy materials is a kind of in 6061 aluminium alloys, 6063 aluminium alloys, 6082 aluminium alloys.Above-mentioned aluminium alloy has that specific tenacity height, color and luster are attractive in appearance, nonmagnetic, the characteristics of good corrosion resistance.Wherein as shown in table 1 as the chemical ingredients of 6061 aluminium alloys, the chemical ingredients of 6082 aluminium alloys is as shown in table 2:
The chemical ingredients of table 1:6061 aluminium alloy
The chemical ingredients of table 2:6082 aluminium alloy
At the above-mentioned surface treatment method that is used for water tap, as preferably, adopt the polishing wheel of rotation that blank is polished in the steps A, the circumferential speed when described polishing wheel rotates is 20～50 meter per seconds.
At the above-mentioned surface treatment method that is used for water tap, the compressed-air actuated air pressure described in the step B is no more than 0.8Mpa.Be that employing pressurized air is that power arrives aluminium alloy blank surface with the material spray high-velocity jet in the sandblast process of the present invention, pressurized air promptly is feed power, be again to quicken power, can produce considerable influence to aluminium alloy blank surface but compressed-air actuated air pressure surpasses 0.8Mpa.
At the above-mentioned surface treatment method that is used for water tap, the material spray described in the step B is a quartz sand, and granularity is 5～220 orders.Quartz sand hardness is big, improves comparatively obvious to the mechanical property on aluminium alloy blank surface.The quartz sand outward appearance uniform particles of Cai Yonging wherein, pure white, the content of silicon-dioxide is greater than 98%.
At the above-mentioned surface treatment method that is used for water tap, acid electrolyte described in the step C is that volume fraction is 10%～30% sulfuric acid, volume fraction is 2%～10% oxalic acid, and massfraction is the chromic acid of 30～100g/L, and massfraction is one or both in the boric acid of 3～10g/L.Adopting sulfuric acid to carry out anodic oxidation as electrolytic solution, to have a cost low, oxide film transparency height, and the porous layer adsorptivity is strong, is easy to paintedly and painted, and painted bright-coloured being difficult for decorporates, and very strong decoration function is arranged.Adopt chromic acid better as the oxide film erosion resistance that electrolytic solution carries out anodic oxidation formation, adopt oxalic acid higher as oxidation film corrosion resistance and hardness that electrolytic solution carries out anodic oxidation formation, porosity is lower.
