Polyethylene board we are very familiar with, has now been used in a large number of industries, supply overwhelmed demand, polyethylene plate with superior wear resistance, self-lubricating, low-cost polyethylene sheet, the intensity is relatively high , chemical stability, strong anti-aging properties and are the majority of users, so are often excellent product will appear a very common problem, and that is the issue of fraud and counterfeiting, customized installation polyethylene sheet, a lot of criminals to see high molecular polyethylene plate demand, on access to ill-gotten gains in its fuss, so today small teach customers to identify several high molecular weight polyethylene plate genuine way, we look together: 1. Weighing law : real proportion of high molecular weight polyethylene plate between 0.93-0.95, less dense and can float on water. If it is not pure polyethylene material, polyethylene sheet, it will sink to the bottom. 2. edge test method: pure rounded end surface of the plate flange, uniform, smooth, polyethylene composite sheet, if not pure polyethylene board material flange end surface cracks, and when heated will appear out after burring Slag phenomenon. 3. Temperature measurement: pure polyethylene plate at 200 degrees Celsius is not melted, will not be deformed, but become soft. If it is not pure polyethylene material 200 degrees Celsius there will be deformed. 4. Visually Methods: The real high molecular weight polyethylene plate surface smooth, uniform, smooth, shiny and black section density is very uniform, if not pure polyethylene plate is faded and uneven density. Polyethylene sheet has good chemical resistance, can be safely used in corrosive environments. In addition, the polyethylene sheet can also be used as additives, added to other compounds to achieve the purpose of improving its chemical properties. Such as the use of vibration rotary stirrer the molten UHMWPE penetrate into the polypropylene, so that the amorphous high molecular weight polyethylene and polypropylene continuous form complex network structure, thereby improving the elongation at break of polypropylene and yield strength.
