Consumers generally judge the most intuitive judgment of stainless steel pipe decoration is its surface brightness. After the stainless steel welded pipe is formed, the surface is smooth and bright, with the primary color of the metal. On the basis of the smooth surface, use polishing equipment (180~600# polishing wheel) to grind the stainless steel decorative tube to obtain the polished surface (round sand/straight wire), also known as the frosted surface, the bright surface, and the high-glossy surface effect. and mirror.
What are the factors that affect the brightness of stainless steel?
1. Surface defects of raw materials. Such as scratches, pits, scratches, trachoma, pickling, etc. The hardness of the raw material is too low, it is not easy to polish during polishing, and the surface is prone to orange peel phenomenon during deep drawing, which affects the BQ performance. The performance of BQ with high hardness is relatively good.
2. The product after deep drawing. Small black spots can also appear on deformed surfaces, affecting BQ performance.
3. The lotion contains too much oil. If the oil in the emulsion cannot be removed in time after carbonization at high temperature, it will accumulate on the surface of the 304 stainless steel pipe, and indentations will be formed after rolling.
The mirror effect of the stainless steel tube can be said to be the representative of high brightness, and the real mirror can only be obtained after the stainless steel is ground and polished. The surface treatment industry of stainless steel decorative pipes is generally divided into two types: wire drawing and bright surface, which are also suitable for the product needs of most customers. Some high-end customers choose mirror stainless steel pipes to make more beautiful products, but of course the cost will increase. Therefore, the bright surface effect of stainless steel pipes is also particularly important.
