Plastic pipe problem: poor tensile strength and toughness. UPVC pipe good tensile strength yield curve should have a clear PVC plastic profiles, large elongation, while the poor often shows brittle plastic pipe, low elongation at break easily understood. Plastic Pipe Problem two: impact poor. According to GB / T5836.1-92 standard test drop hammer impact test, detected many years PVC plastic prices and pass rate was less than 50%, or even 10 times the impact of many products, all broken. Plastic pipe Question three: softening temperature is low, easy to deform when exposed to heat. Performance on the test performance, that is the Vicat softening temperature is low (less than 79) PVC plastic wholesale, some manufacturers to increase the softening temperature, simply increase the amount of filler at the ingredients, do indeed improve the softening temperature, but make Pipe other properties, especially impact resistance, tensile strength, toughness greatly reduced, so to increase the softening temperature, without lowering or less lowering other properties, should aid in the selection ratio of raw materials, production processes, and production mechanical work on, can not be taken lightly. UPVC pipes UPVC pipes, according to the national standard GB / T10002.1-1996 testing, hydraulic testing its high performance requirements of the standard value, which UPVC water supply pipe production companies made high demands. The problem is one of the common eccentric plastic pipe problem, it will lead to the production of plastic pipe wall thickness unevenness larger PVC plastic, which is not only a waste of raw materials, but also make it difficult to achieve the loop hydraulic test performance requirements 42MPa of stress of plastic pipe production line operations cause a great impact. Therefore, the production of which requires enterprises not only make a good material ratio, qualified enterprises should be installed on-line detection equipment, always adjust the size of the deviation of plastic pipe. PVC (polyvinyl chloride) chemical and physical properties of rigid PVC is one of the most widely used plastic materials. PVC material is a non-crystalline materials. PVC material in actual use, often by adding stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives. Runners and Gates: All conventional gate can be used. If the processing of smaller components, it is best to use the tip gate or sneak into the gate; for thicker parts, it is best to use the fan gate. The minimum diameter of the tip gate or sneak into the gate should be 1mm; fan gate thickness not less than 1mm.
