Qingdao Jia Sen plastic machinery factory specializing in the production of PPR plastic pipe equipment, is an enterprise specializing in the production of plastic pipe fitments PPR plastic pipe equipment production is the use of German design and manufacture of the latest technology, high-speed production PPR PPB pipe, out of the product by the National Chemical Test Center test to achieve the quality of the international ISO-DIS15874-22-98PP-R pipe ... Contact: Song Kun Tel: 13964225913 PPR pipe production line, PPR pipe uses and characteristics: PP-R drinking water pipe system today new products commonly used in developed countries in the world, access technology, its technical performance and economic indicators are far superior to other similar products, especially its excellent health performance using homogeneous dissolved in the hot and cold water delivery project, from production to use to abandoned counterassaulted the whole process can achieve high health and environmental requirements. products have the advantages of heat, pressure, thermal insulation, energy-saving, long life and economy. PPR pipe production processes raw material masterbatch → mixing → vacuum on the raw material is dried materials → → single screw extruder → color line extruder → the spiral mold → given diameter sets → spray vacuum calibration tank → spray cooling water tank the → the Stenciling → crawlers machine → finished product testing packaging PPR pipe production line, PPR pipe production process has encountered a problem how to solve a coke track possible causes of the temperature of the body or head tube surface; nose and filtration is not clean; pellets impurities; the raw thermal stability is poor or too little heat stable dose; temperature control instrumentation malfunction. 2, the pipe surface clean black streaks may cause nose temperature is too high, the filter is not cleaned. Pipe Matte die temperature is too low or too high. 4, the pipe surface wrinkles may be uneven around the die temperature; cooling water is too hot; the traction too slow. 5, the pipe wall rough mandrel temperature is low; body temperature is too low; screw temperature. Pipe wall cracks might be expected to have impurities; mandrel temperature is too low; low body temperature; traction too fast. 7, the tube wall the rugged might screw temperature; screw speed is too fast. 8, the inner wall of the tube bubbles may be material damp. 9, uneven wall thickness may die, core die is not positive; uneven nose temperature; traction unstable; compressed air unstable. 10 pipe bend pipe wall thickness uneven; nose four weeks uneven temperature; the head cooling tank, traction cutting centers not positive; different cooling slots at both ends of the hole heart. 11 products brittle hair may be the plasticization of the fuselage is not enough; screw speed is too fast; die temperature is too low; resin viscosity is too high. 12 pipe longitudinal or transverse shrinkage probable sizing sleeve and the inner diameter of the die radial (horizontal); traction high speed (vertical). 13, suddenly discharging slow might screw feed zone temperature is high; fuselage water; small nose lysosomal pressure.
