Routing the world bellows is a synthetic material with a PVC, and now it also occupies a market position in the market is unusual, respectively, have different delivery methods, bellows occupy important in production The status of development in recent years, is an improvement to technology has made a breakthrough. Bulk polymerization production process, its main feature is the reaction process does not need to add water and dispersants. Routing general bellows guaranteed bellows manufacturers, it means there are polymeric materials and vinyl chloride, and so has the characteristics of filtered, compressed and condensate recovery, high pressure water cleaning, grading adjust so a variety of operations. The main steps of polymerization in two stages, namely the pre-polymerization and polymerization. Terminated when the reaction conversion reached 60% to 85% (depending on the formulation may be) the reaction, and degassed in a polymerization vessel, to recover the unreacted monomer, and then the autoclave stripped further remove remaining in the tubing, Finally, the system will send the wind pipe powder sent to grading, homogenization and packaging processes, so it is the same process route, there are different. First, a low modulus of elasticity of the elastic modulus of the glass tube steel (E = 2.1E5) 10 times smaller, and therefore the product structure often feel less rigid hdpe corrugated pipe manufacturers, easily deformed. Shell structure can be made, however, sandwich mpp bellows manufacturers, but also by high-modulus fibers, or do other forms of reinforcement to compensate. Second, the long-term temperature and poor long glass pipe can not be used in high temperature, general polyester FRP strength is above 50 ℃ decreased, generally used only in the following 100 ℃; universal epoxy FRP above 60 ℃, the strength significantly decline. Third, the aging phenomenon in the UV, rain and sand, chemical media, mechanical stress, such as the role of the old glass pipe easily cause performance degradation. Fourth, the interlaminar shear strength between the lower shear strength is borne by resin upvc bellows manufacturers, so low. By selecting the technology, using coupling agents and other methods to improve adhesion between layers, most notably in the product design, so try to avoid inter-layer shear. hdpe corrugated pipe manufacturers, 吕梁波 bellows manufacturers, provided by Xiong Xiong Lei Lei Thai Thai Plastic Pipe Manufacturing Co., Ltd.
