Why can't a ultra-high molecular weight polyethylene plate hot forming? - - - - - - Union star packaging machinery

Ultra-high molecular weight polyethylene plate is a kind of high viscosity of the polymer, as the powder shape, the typical particle size range of 100-200 microns. Ultra-high molecular weight polyethylene plate because of the high viscosity, so can't use common thermoplastics forming methods for processing, but with the high temperature moulding or plunger extrusion process, the ultra-high molecular weight polyethylene particles melt under high temperature and high pressure and sintering of PiCai or profile, if necessary, for subsequent machining. Ultra-high molecular weight polyethylene plate can also be modified additives, its wear resistance and corrosion resistance makes it a distinct advantage in chemical machinery. Using ultra-high molecular weight polyethylene products instead of the metal material acid proof pump, transmission machinery, water pumps, shaft sleeve, sealing plate, gear, etc. , not only greatly extended service life, and thus greatly reduced the cost. Ultra-high molecular weight polyethylene can also be modified additives, added to other compounds to achieve the purpose of improve its chemical properties. Such as the vibration rotary mixer can make molten pervades ultra-high molecular weight polyethylene polypropylene, make the amorphous formation of ultra-high molecular weight polyethylene and polypropylene complex continuous mesh structure, thus improve the elongation at break and the yield strength of pp. Ultra-high molecular weight polyethylene also can be used as the impact strength of polypropylene crosslinking modification agent, the tensile strength and toughening modifier enhancer.
