Wear-resistant PU steel wire duct for printing presses such as KBA, Roland, Heidelberg, etc.
   The wear-resistant pu steel wire ducts used by well-known brands of printing presses such as KBA, Roland, Heidelberg, etc. on the market basically use German imported hoses, especially black ones, which are basically not stocked in China. It is difficult Purchased black printing press air ducts, but today, Hangzhou Haikuo produces various specifications of black pu steel wire hoses, which are mainly sold to various printing machinery manufacturers.
   The material and production process of the black printing press air duct are exactly the same as the transparent PU steel wire duct. The only difference is the addition of black toner. In addition to the difference in color, the transparent pu duct is the same as the black pu duct. There is no difference in the nature of the tube. Because many of the original printing machine air tubes are black, there are often customers who want to use the same color as the imported hose.
  The air duct of the printing machine is made of wear-resistant pu polyurethane material, which can be said to be the most wear-resistant hose among similar plastics. Of course, it is also a high-temperature air duct. Its temperature range is -40°C. To 125°C, it can reach 150°C in a short time. Compared with PVC or other plastic pipes, this material is considered to be quite resistant to temperature.
   This kind of wear-resistant pu duct is not only used for ventilation on the printing machine, but also suitable for the plastic industry, conveying particles and powder: particle conveying device, vacuum hopper/conveyor, suction conveyor, batching system, batch Loading (large packaging)-loading and unloading, paper shredders, grinders, extruders, injection molding machines, film blowing machines, cooling air for extrusion tools, printing machinery, air supply: air supply cabinets, offset printing machines, textile industry, steam extraction Suction: steam iron, industrial ironing machine, flat iron, raw material conveying hose for powder, granule, sand, stone, gravel, debris/shavings, compressor, side blower, vacuum pump, pressure pump, pump.
   Wear-resistant PU steel wire duct has good heat resistance, heavy duty, high wear resistance (wear resistance is 2.5 to 5 times that of most rubber materials, and 3 to 4 times that of most soft PVC materials), inside Smooth, excellent passability, good oil resistance, chemical resistance, good UV and ozone resistance, small bending radius, not easy to kink, no softener and halogen, anti-gas and liquid leakage, in line with SGS, according to Germany TRBS 2153 (formerly BGR 132): It can discharge static electricity through grounding. It is recommended for occasions with flammable and explosive powders.
   At present, many users do not blindly pursue imported air ducts when the air ducts of the printing press need to be replaced, because the imported pu air ducts of the same kind are 5-8 times more expensive than the domestic ones, of course they are imported. The quality of the hose is really nothing to say, but the high cost and the delivery time of more than two months have made many businesses no longer want to continue to order imported PU ducts. Can the domestic printing press air ducts be used in place of imported hoses? Of course, the answer is yes. The merchants are very clever, using 1 times the cost for 1 year, and 5-8 times the cost. With 2 years, this will of course choose the former. It is more convenient to use domestically produced products, because for this type of product, it takes a long time to replace it, and it is only changed once in some years. When it is replaced, you may not be able to wait for two months to purchase imported hoses. However, The domestically produced ones may arrive on the same day, and not only transparent printing press air ducts, but now even black printing press air ducts can also be produced, which brings great convenience to printing machinery users.
