PE-RT floor heating pipe production line, PERT pipe production equipment PE-RT pipe production requirements of the good performance of the raw material "Copy" to the pipe, and hope to achieve fast continuous extrusion to produce quality products and achieve better economic efficiency The purpose of PE-RT pipe production line with the general basic structure of polyolefin pipe production line, the main difference lies in the different parts of the structure of the cooling sizing. Such as floor heating pipe production line, polybutylene melt viscosity, in order to successfully enter the sizing sleeve tube to warm the pipe production line manufacturers, general sizing sleeve before adding a pre-cooling loop. In addition, due to the large enthalpy polybutylene, in order to speed up the cooling rate, you can use a combination of tube type and disc-type cooling shaping device. Structural sizing sleeve, the machining accuracy and cooling method for processing PE-RT pipe quality is very necessary. Disc water ring sizing sleeve (cooling water for sizing the circulating cooling water jacket to warm the pipe production line in Qingdao, the cooling water does not touch the pipe) in the production of thin-walled (cold water) short tube, but when the material into the sizing sleeve high temperature, the larger the viscosity, the use of traditional water membrane sizing sleeve in the long production will cause the pipe to pull off even the appearance of increasingly rough, so, PE-RT pipe production, using curtain disc type sizing sleeve before entering the pipe sizing sleeve its pre-cooling, in addition, also to prevent the material adhering to the sizing sleeve entrance, causing obstruction. PE-RT thermal capacity is large, especially at high speed to make the tube, in order to meet fast extrusion speed you need to configure a longer length sizing and cooling to meet the cooling needs of the high-speed production and stereotypes. One, PERT pipe production processes raw + masterbatch mix → → → raw material vacuum drying → single screw extruder → spiral mold → → spray vacuum sizing sleeve styling spray cooling water tank box → → → Stenciling crawler tractor → winder → finished product testing package two, PERT pipe production process incurable 1. How to solve the pipe surface coke may be due to trace the body or head temperature is too high; the head and did not clean the filter ; pellets impurities; poor thermal stability raw or heat-stable dose is too small; temperature control instrumentation failure. 2. The pipe surface with black stripes possible causes head temperature is too high, the filter is not clean. 3. Pipe Matte probably die temperature is too low or too high. The pipe surface wrinkles may be uneven temperature die four weeks; cooling water is too hot; traction too slow. 5. rough inner wall of the pipe may be lower mandrel temperature; body temperature is too low; screw temperature is too high. 6. pipe inner wall cracks may be expected to have impurities; mandrel temperature is too low; low body temperature; traction too fast. 7. Screw the tube wall may have uneven temperature is too high; screw speed is too fast. 8. tube wall material bubbles may damp. 9. uneven wall thickness may die, mandrel no positive; head temperature uneven; traction unstable; compressed air is unstable. 10. Pipe bending pipe wall thickness may uneven; head around the uneven temperature; head cooling tank, traction cutting centers no positive; different ends of the cooling tank hole heart. 11. brittle hair products may not be the extent of plasticized body; screw speed is too fast; head temperature is too low; resin viscosity is too high. 12. vertical or horizontal pipe sizing sleeve may shrink large radial die bore a large difference (horizontal); High Speed ??Traction (vertical). 13. The sudden discharge screw feed zone may slow high temperature; body water; melt pressure head warm small pipe production line machinery | floor heating pipe production line | Day letter provided by the Qingdao-day letter Thai Thai Plastic Machinery Co., Ltd ..
