Plastic pipe problem: poor tensile strength and toughness. Good UPVC pipe tensile strength yield curve should have a clear, large elongation, and the poor often engendered brittle plastic pipe, low elongation at break easily understood. Plastic pipe problem: the impact poor. According to GB / T5836.1-92 standard test hammer impact test, years detected Qingdao plastic extrusion products, once-through rate was less than 50%, or even 10 times the impact of many products, all broken. Plastic pipe Question three: the 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) of plastic extrusion products, some manufacturers to improve the softening temperature, simply increase the amount of filler at the ingredients, this can indeed improve the softening temperature of the plastic extrusion article price, but the other properties of the pipe so that, in particular, impact resistance, tensile strength, toughness is greatly reduced, and therefore to increase the softening temperature, with little or reduced without reducing other performance additives selected should be in the ratio of raw materials on the production process, and production machinery to work on, 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 a common one eccentric plastic pipe problem, it will lead to the production of plastic pipe wall thickness greater degree of unevenness, which is not only wasteful of raw materials, but also make it difficult to achieve the required performance hydraulic test loop stress 42MPa, the pair plastic pipe production line operation caused great impact. So which requires manufacturers not only make a good material ratio, qualified enterprises online testing equipment should be installed at any time to adjust the size of the deviation of plastic pipe. Garnish began to structure, functional parts within the current direction of development, building materials and other products from plastics. Plastic flooring, wall decoration pieces sales maintained a steady growth, polymer building templates, waterproof materials, wall supports, wall insulation boards, bricks and other plastic strengthen more and more applications, the growth rate is more than the plastic pipe. Expected in the next 5-15 years of plastic extrusion products offer, under the guidance of various national building energy efficiency policies, plastic building materials market is expected to be more rapid development. To 2015, China all kinds of building plastic pipes and plastic doors and windows average market share will reach 50% and 30%, respectively. The demand side, a variety of architectural plastic pipes and plastic doors and windows plus polymer waterproof materials, decoration materials, insulation materials and other plastic products used in construction, total demand is expected to reach 10 million tons.
