Pipe color:
Now on the market of PPR pipe white, gray, green and many other colors for consumers to choose from, many small manufacturers of white PPR pipe was gray or white porcelain, gray is dark gray, which is mainly manufacturers in the production During the process to add a lot of calcium powder, many customers live in new homes 2-3 years after the discovery of home buried pipeline powder, Weld off caused by leakage is due to this reason, but the big brands of products are usually natural pigment and the German PPR Particles, either white or green are very pure.
Pipe material:
PPR pipe quality is ultimately reflected in the quality of raw materials, China's national standard PPR production of raw materials can be recycled 10% of the added material, some small plants added more than 50% of recycled materials, not only can not guarantee the quality of products for drinking water The pipeline also failed to meet health standards. European standard PPR raw materials must be pure PPR particles, strictly prohibit the addition of any recycled material.
Pipe production process:
Good PPR pipe touch the surface smooth, uniform wall thickness, and poor the opposite of the pipe, resulting in this situation mainly related to equipment and production processes, many of the factory's production equipment itself is not high precision, the production process and no testing Equipment timely detection and correction, it will result in uneven wall thickness, the surface is not smooth and so on.
Zinc or Nickel Plating Production Line
Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.
Zinc-nickel alloy is an anti-corrosion coating with excellent corrosion resistance. At the same time, it has good mechanical properties and does not change the mechanical properties of the steel after plating. It has excellent brazing properties and is easy to weld under various conditions. The internal stress of the coating is small, which is comparable to that of the cadmium coating in the torsion-tension test. The plating solution has good dispersing ability and covering ability, high current efficiency, bright and smooth coating.
The zinc-nickel alloy plating bath has weak acid chloride type, sulfate type and alkaline zinc acid type.
The surface condition and processing requirements during electroplating, select the appropriate steps, and perform the necessary finishing processing on the surface of the part, so that the part has a smooth and clean surface, which is an important link in obtaining a high-quality coating.
