Stainless steel processing reference content
Stainless steel surface are often written by Hu graffiti, but it's an important feature is they can be washed, which is stainless steel better than aluminum for a distinctive feature. Easy to leave marks on the surface of aluminum is often very difficult to remove. Clean stainless steel surface should be along the lines of stainless steel clean-up, because some of the surface processing of the lines is one-way. Stainless steel ideal for a hospital or other critical areas of health conditions, such as: food processing, food, brewing and chemical, not only because it is easy to everyday cleaning, and sometimes have to use chemical cleaning agents, but also because it is difficult to breed bacteria. Results show that the performance of stainless steel in this area with the same glass and ceramics.
First, the natural look of stainless steel
Solid stainless steel gives a natural feeling of bright, soft colors reflect the natural color of the surrounding environment.
Second, the basic types of surface processing
Stainless steel surface processing can be used to roughly five, they can be used in combination, transform more of the final product.
Five categories are: rolling surface processing, surface processing machinery, chemical surface processing, textured surface finish and color treated. There are also special surface finish, but no matter what kind of surface finish specified, should follow the following steps:
① Together with the manufacturers agreed on the need for surface processing, it is best to prepare a sample for future mass production standards.
② Widespread use (such as composite panels, to ensure that the base coil or coils used in the same batch used.
③ In many construction applications, such as: elevator inside, though fingerprint can be erased, but very beautiful. If you choose Gyrosigma surface, not so obvious. In these sensitive areas must not use mirror stainless steel.
④ Select surface finish should take into account production process, such as: In order to remove the welding bead, may need to weld grinding, but also to restore the original surface finish.
⑤ For some surface processing, grinding or polishing of the texture is directional, is known as one-way. If you use so that the vertical rather than horizontal lines, dirt will not easily attached to the top, and easy to clean.
⑥ Either finishing process steps need to increase, so to increase the cost, so choose carefully when the surface processing.Thus, architects, designers and manufacturers and other relevant staff need to understand processing of stainless steel surface. Friendship through mutual cooperation and mutual exchange, will receive the desired results.
⑦ In our experience, we do not recommend the use of alumina as abrasive, unless very carefully during use. It is best to use silicon carbide abrasive.
Third, the standard surface machining
Many types of surface processing has always been to number or other classifications indicated that they have been incorporated into the relevant standards, such as: 'British Standard BS1449' and 'American Iron and Steel Institute Buxiu Gang Producers Council standards'.
Fourth, the rolling surface processingPlate and strip rolling
There are three basic surface finish, they are through the plate and strip production process of the village expressed.No.1: After hot rolling, annealing, pickling and descaling. Treated steel surface is a dark surface, a bit rough.No.2D: surface finish better than the N0.1 is bleak surface. After cold rolling, annealing, descaling, and finally with light hair roller rolling surface. No.2B: This is the most commonly used in construction applications, in addition, after annealing and descaling with a mild polishing the final cold roll, the other process with the same 2D surface, some a little light, can be polished.No.2B bright annealing: This is a reflective surface, polished roll rolling and final annealing in controlled atmosphere. Bright annealing still maintain its reflective surface, but does not produce oxide.As the bright annealing process of oxidation does not occur, so no need for pickling and passivation.
Fifth, the polished surface finish
No.3: said by the 3A and 3B. '3A: After the surface evenly grinding, abrasive particle size of 80 to 100.3B: hair surface polishing, the surface of a uniform straight grain, usually with a size of 180 ~ 200, 2A, or 2B belt in a polishing board formed.No.4: one-way surface processing, reflection is not strong, such a surface finish may be the most widely used construction applications. The process steps are first to use coarse abrasive polishing, the final size of 180 then the abrasive grinding.
