A variety of surface treatment that stainless steel place has widened its applied domain- - different exterior treatment makes stainless steel surface each different, make its have original place each in application. The field uses in the building, the surface of stainless steel machines what if have a lot of reasons,weigh. It is not easy that corrosion environment asks because the surface is slick,slick surface is scale. The deposit meeting of bilge makes stainless steel rusty cause even corrode. In capacious hall, stainless steel is the material with elevator outfit the most commonly used plaque, although exterior fingerprint is OK erase, but the influence is beautiful, had better choose appropriate surface to prevent to keep an impression of the hand so. Wholesome condition is very important to a lot of industries, for example, food treatment, meal, brew and chemical industry, the field uses in these, the surface must facilitate clean everyday, and often want chemically to clean an agent. Stainless steel is the optimal material of this respect, be in public, the exterior classics regular meeting of stainless steel is written by moustache graffito, but, a its main character is OK clean them, this is a of aluminium of stainless steel excel marked characteristic. Aluminous surface leaves a mark easily, often very difficult take out. Clear should clear down the grain of stainless steel when stainless steel surface, because have some of face,the grain of treatment is one-way sex. Stainless steel most apply to the domain with hospital or other sanitation crucial condition, be like: Food treatment, meal, brew and chemical industry, because it facilitates,this is not only clean everyday, make chemically cleans an agent even sometimes, and because it is not easy,still cause a bacterium. The experiment shows stainless steel is in the function of this respect and glass and pottery and porcelain are identical. 1. The natural exterior stainless steel of stainless steel shines of a kind of nature stably to the person beautiful feeling, blandly of its nature colour reflects the facial expression that gives surroundings. 2. The basic sort that the surface machines can be used at the exterior treatment of stainless steel to have 5 kinds roughly, they can be united in wedlock rise use, commutation gives more end item. 5 sort have: Rolling surface treatment, mechanical surface treatment, chemical surface treatment, reticulation surface treatment and chromatic surface are machined. Still have treatment of surface of a few appropriative, no matter appoint which kind of surface treatment,do not pass, should follow the following move: ① and manufactory home decide the surface of need is machined together, had better prepare a sample, as the standard that batch will produce henceforth. When ② large area is used (be like compound board, the base that must assure to use coils board or roll what material uses is same batch. ③ is in a lot of building application, be like: Elevator interior, although fingerprint is OK erase, but very not beautiful. If choose cloth grain surface, so not apparent. In these sensitive places scarcely can use lens face stainless steel. When the surface is machined, ④ choice should consider the craft that make, for example: For eliminate solder bead, the likelihood should undertake repairing grinding to welding line, and restore original surface to machine even. Decorative pattern board cannot satisfy this one requirement very hard even. ⑤ is machined to some surfaces, long grind or the grain of polishing is tropism of in the right way, be called one-way. If use when make this kind of lines plumb is not a level, contamination adheres to not easily above, and clean easily. No matter ⑥ uses which kinds of finish machining to need to add technology measure, because this wants to raise cost, so, when the surface is machined, the choice wants discreet. Accordingly, the exterior treatment that the concerned personnel such as personnel of architect, design and manufactory home needs pair of stainless steel understands somewhat. Pass the friendly collaboration between each other and mutual communication, regular meeting achieves the result of an expectation. ⑦ basis our experience, we do not suggest use alumina makes abrasive, in unless be in,using a process very careful. Had better be use carborundum abrasive. 3. Standard surface treatment makes a variety of surfaces machine is to use number or other classification method to express all the time, they were enrolled in the standard that concern, be like: "British standard BS1449" and " of level of commission of generator of stainless steel of steely association of " United States. 4. Plank of rolling surface treatment and strip have 3 kinds of basic rolling faces to machine, they are to adopt plank and the manufacturing technology that bring a village denotive. No.

1: Classics overheat make friends, anneal, pickling and remove like the scales of a fish. The armor plate surface after processing is a kind bleak the surface, a bit coarse. No.

2D: Than N0.

1 surface has been machined, also be bleak the surface. Classics super-cooling make friends, anneal, remove like the scales of a fish, use light roll of wool face roller finally. No.

2B: This is the most commonly used in building application, except mix in anneal outside after removing like the scales of a fish, undertaking spending cold rolling gently together finally with polishing roller, other craft and 2D are identical, the surface slightly some give off light, can undertake polishing is handled. No.

2B shining anneal: This is surface of sex of a kind of reflex, the course casts smooth roll rolling and final anneal undertakes in can accuse atmosphere. Shining anneal still maintains his to reflex the surface, and do not produce oxidation skin. Because oxidation reaction does not produce in shining anneal process, so, do not need to undertake pickling and passivation are handled again. 5. Polishing surface machines No.

3: Express by 3A and 3B. "3A: The surface passes even ground abrade, abrasive granuality is 80 ～ 100. 3B: Wool face polish, the surface has even straight grain, it is for 180 ～ with granuality the arenaceous belt of 200 is in normally 2A or 2B board cast last time grind and become. No.

4: One-way surface is machined, reflection sex is not strong, treatment of this kind of surface is building the utility in application the widest. Its technology measure is to use thick abrasive polish first, final reoccupy granuality is the abrasive of 180 abrade. No.

6: It is pair of No.

Improve of 4 further, it is with Tanpike in abrasive and oily medium polishing brushs polishing No. 4 surfaces. "England does not have this surface treatment in standard 1449" , but can check in American standard. No.

7: Polish of the brightness that be called, it is very fine to been grind but still the face that wears mark undertakes polishing. What use normally is 2A or 2B board, cream with fiber or cloth rag wheel and corresponding polish. No.

8: Surface of lens face polish, reflectivity is tall, be called normally treatment of lens face face, because its catoptric picture is very clear. With fine abrasive successive to stainless steel polish, next the polish with very fine reoccupy creams burnish. If be used in personnel flow to measure,what should notice in building application is this kind of surface bigger or the place that people often feels can keep an impression of the hand. Fingerprint is OK of course erase, but affect sometimes beautiful. "The exterior treatment of the description in official " standard and document is run-of-mill introduction only, example ability represents the sort that the surface machines the most intuitionisticly. Polishing or manufacturer of metallic finish machining will offer the sample that all sorts of surfaces machine, the user should undertake discussion with them. 6.

Treatment of surface of rolling of exterior surface roughness and the classification that polishing surface machines are the level that the specification can reach, another effective expression the method is to measure exterior surface roughness. Standard measurement technique is called CLA (central line average) , the measuring instrument is in armor plate face is transverse and mobile, the record leaves the metabolic range of peak cereal. The number of CLA is smaller, the surface is slicker. 7.

Mechanical polish note: We should remember, what undertake with sand paper or arenaceous belt in abrade operation is abrade basically belong to burnish cut is operated, very fine grain stays in armor plate surface. We ever had encountered a trouble when serving as abrasive with alumina, its part reason is pressure problem. Any abrade components of equipment, be like: Arenaceous belt and grind annulus etc, before using, cannot use at material of other blame stainless steel absolutely. Because such meetings pollute stainless steel surface. To assure the consistency that the surface machines, new emery wheel or arenaceous belt should the try out on the waste material with preexistence same class status, so that be the same as sample,undertake comparative. 8. Electroanalysis polishing this is a kind of metal cleared craft, in this craft stainless steel regards electrolyte as medium positive pole, the metal after electrify from surface layer eliminate. This craft is used at the treatment of component normally, because their appearance uses traditional method hard,undertake polishing. This craft is commonly used the surface at cold rolling armor plate, the face that because of its the surface compares hot-rolling armor plate is smooth. But electroanalysis polishing can make exterior impurity more apparent, especially the material that titanium and niobium turn firmly can make as a result of graininess impurity welding line area appears difference. Small solder scar and acute arris can keep clear of through this craft. This craft emphasizes processing apparently salient, preferential undertake dissolving to them. Electroanalysis polishing craft is immerse stainless steel in the liquid that heating, liquid deserves to arrive than involving a lot of have technology and patent technology only. Of austenite stainless steel electroanalysis polishing effect is very good. 9. The figure that stainless steel of reticulation surface treatment can use is a lot of more phyletic. Make armor plate has the good point that adds decorative pattern or reticulation surface treatment to be as follows: ① reduces " of shrinkage of material of " metal roofing (Oil Can-ning) , this word is a term that uses face of descriptive brightness material, this kind of surface looks from optical angle rough. For example: The outfit plaque of large area, although pass drawing Jiao Zhi or tension to pull correct to make the surface very hard also completely flat, can give cash to belong to roofing material shrinkage consequently. ② reticulation design can reduce the dazzle that gives out below sunshine. ③ decorative pattern board if have slight nick and small area impress not quite apparent. ④ increases the strength of armor plate. ⑤ provided the margin of the choice for architect. The pattern that has patent includes cloth grain (the dust heart large building that uses Yu Lundui) , enchase shape of design, pearl and leather grain. Still can use ripple and linear design. Decorative pattern appearance is special agree with in-house adornment, be like: Elevator panel, bar, wainscot and entrance are in. When exterior applying, should consider make stainless steel can be mixed through rainwater erode artificially wash the face, avoid to have the dead space of the impurity in contamination of Yi Ju collect and sky, lest cause,corrode an influence beautiful. 10. Treatment of face of face of wool of treatment of wool face face is one of the most commonly used surface treatment, it is nylon is used in the armor plate surface that passes polishing or shining anneal abrade belt or brush undertake polishing. 11.

Gush glass ball or gush bolus apply to interior, be like: The interior of elevator, mixture surface treatment is very popular. This kind of mixture craft is to pass gush glass surface of globose Cheng Moze, handle through concealing next, clothe is plastic film, into polishing surface treatment, form finally polishing and without lustre mixture surface. Stainless steel arenaceous bolus also can be used at similar technology. The vitreous ball that should use or pill cannot be used on other material absolutely beforehand, cannot go up in carbolic steel especially. Can embed because of the powdery bead of carbolic steel stainless steel surface, cause very easily corrode. Ball of pottery and porcelain also can serve as gush makings. 12. Craft of color of stainless steel of chromatic stainless steel is international nickel company (INCO) 70 time develop a success, a lot of companies have the permit that uses this one technology. Had explained in front, because the affection sex of its surface layer oxidizes,stainless steel does not rust is chromic film. Chromatic craft uses this film to form velar color namely. Because stainless steel used this film that exists from beginning to end, so both neither fade, also do not need to often be safeguarded like paint. Chromatic stainless steel still can undertake shaping handling, although be in,acute curved place also won't have any undesirable effects to color. Be able to bear or endure about be opposite the influence of corrode sex, the experiment makes clear to corrode sex is able to bear or endure to increase somewhat after using this technology. Closely related this craft and operation time, different color can produce time change. The metabolic order of color is brown, aureate, gules, purple and green. The final exterior that the one big characteristic of this craft is it can reflect the face with this original material, namely: Lens face or polishing face can produce very strong metal burnish, and the color that wool face face machines is lacklustre. Process: This craft is immerse stainless steel in solution chamfer, had better be every litres contain 250 grams Cr2O3 in solution, every litres contain 490 grams vitriolic OK also, temperature limits 85 ℃ of 80 ～ , immerse time depends on the color of a need, do not exceed 25 minutes at most. After using board clean cold water full, it is 250 grams to chroma in transfer to a lower level of room temperature condition again / 1 litre of chloric acid and 2.

5 grams / undertake cathode is handled in the liquid of 1 litre of phosphoric acid, time is 10 minutes about, current density is 0. 2 ～ 0. 4A/dm2. To prevent damage, sclerotic processing undertakes instantly after color is handled, undertake full in hot water next and dry. 13. Mixture surface treatment can impose pattern again on chromatic stainless steel, what develop only the technology includes to use corundum arenaceous tape part of eliminate " outstanding " , such, the colour that final result is the natural beauty armor plate and chromatic design is united in wedlock together. This kind of surface keeps an impression of the hand not easily, special apply to interior decoration. Polishing manufacturer can offer the sample that the surface machines. 14. Etch exterior treatment is in design award through laminating craft armor plate surface, be in armor plate dip again acerbity fluid of 3 chloridize iron (O class) in, will not the partial dip corrode of laminating is dropped, beautiful design is formed in the surface of stainless steel.
