Why choose cylindrical screen changer for blown film screen changer?
Non-stop screen changer for blown film On large single-layer and multi-layer co-extrusion blown film units, we use cylindrical screen changer for non-stop screen changer. On the one hand, the column-type screen changer adopts high-performance steel and special processing methods and heat treatment methods, and is equipped with pressure-stabilizing, lubricating and sealing mechanisms; Switching is smoother. The cylindrical screen changer adopts a unique sealing system and high temperature lubrication system to "cooperate" so that the main body of the screen changer can withstand a pressure of 40~60MPa, and there will be no leakage of material for 4~5 years. Cylindrical continuous screen changer "relay" automatic exhaust during screen changing operation, no shutdown, no deceleration, no material leakage, no oil leakage. On the other hand, the screen changer for film blowing has high requirements on the pressure resistance value, and the fluctuation of the screen changing pressure is small, and there will be no leakage of material after long-term use.
After installing the cylindrical screen changer, it can not only filter out impurities, but also greatly improve the plasticization and homogenization effect of raw materials, and the product texture is more uniform, and the surface quality and smoothness are better. In addition, the filter screen can be replaced without stopping the machine, which saves energy and reduces consumption. At the same time, the output is increased and the labor intensity is reduced. hydraulic screen changer manufactuers firstname.lastname@example.org
