In recent years, growth in the number of PVC in Southeast Asia is particularly significant, thanks to the Southeast Asian countries have carried out urgent infrastructure needs. In the three-dimensional surface film can produce the material. PVC can be divided into soft PVC and rigid PVC. Hard PVC market which accounts for about two-thirds of soft PVC 1/3. Soft PVC are generally used for surface floors, ceilings and leather, but because of soft PVC containing softener (which is soft PVC and rigid PVC difference) small pipe production line, pipe production line pa easily become brittle and difficult to save, so its use been limited. Hard PVC free softener pipe production line, so flexible, easy molding, hard brittle, non-toxic and pollution-free, save for a long time, so it has great development and application value. Below are referred to PVC. PVC is essentially a vacuum plastic film for packaging various types of panel surface, it is also known as decorative films, with film, used in building materials, packaging, pharmaceutical and other industries. Building materials industry accounted for the largest proportion pipe extrusion production lines, 60%, followed by industry, packaging industry, there are a number of other small-scale applications. PVC pipe characteristic 1, PVC pipe is light, convenient transportation and handling; PVC pipe material is very light and convenient loading and unloading of construction, saving labor 2, PVC pipe excellent chemical resistance, resistance **; PVC pipe has excellent resistance to acid, alkali corrosion resistance, for the purposes of the chemical industries. 3, PVC pipe fluid resistance; the smooth wall PVC pipe for fluid resistance small, the drag coefficient of only 0.009, lower than other pipes in the same flow, the diameter can be reduced. 4, PVC pipe mechanical strength; pressure resistance strength of PVC pipe, pressure-resistant strength, impact strength etc very good for a variety of conditions of piping works. 5, PVC pipe good electrical insulation; PVC pipe full of excellent electrical insulation, used in wires, cables of catheter, and wire construction on the pipe. 6, PVC pipe does not affect the water quality; PVC pipe by dissolution does not affect the water quality tests confirmed the best pipe for the current of the water piping. 7, PVC pipes simple construction; quickly and easily bonded construction of PVC pipe, so the low cost of construction projects. Extruded pipe production line, pipe production line, with three presses offered by Qingdao Plastic Machinery Co., Ltd., with three. Plastic Machinery Co., Ltd. Qingdao with three (www.tongsansuji.com) strong, credible, Qingdao, Shandong Province in other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead you to join with three presses and into the brilliant, for a better future!
