The vacuum panel on the surface of the suction box is made of composite ultra-high molecular weight polyethylene board, and its mechanical properties are higher than that of ordinary high-density polyethylene. It has outstanding impact resistance, stress crack resistance, high temperature creep resistance, low friction coefficient, self-lubrication, excellent chemical corrosion resistance, fatigue resistance, noise damping, nuclear radiation resistance, etc.
The use temperature is 100~110℃. It has good cold resistance and can be used at -269℃. The product with a density of 0.985g/cm3 and a molecular weight of 2 million has a tensile strength at break of 40MPa, an elongation at break of 350%, a flexural modulus of elasticity of 600MPa, and the cantilever beam notched impact is continuous. Abrasion (MPC method) 20mm, the paper industry is the most common field of UHMWPE application, using the abrasion resistance and impact resistance of UHMWPE, it can be used to manufacture deflector wheels, scrapers, nozzles and filters Wait.
UHMWPE can be widely used in suction box cover and wiper plate of paper machine. It protects expensive copper mesh or stainless steel mesh, reduces downtime, and creates great economic benefits for the paper industry. At present, the amount of ultra-high molecular weight polyethylene required by the paper industry accounts for 10% of its total consumption, which has created great economic benefits for the paper industry
