Performance of Polypropylene Melt Pump

Polypropylene melt pump is a polymer melt with high temperature and high viscosity. Therefore, the first requirement is that the pump has high temperature resistance, that is, at working temperature, all parts of the pump should have sufficient strength and stiffness, parts subject to alternating load should have high fatigue strength, wear parts should maintain high hardness and wear resistance. The expansion coefficients of each mating part should not be too different. Secondly, the pump is re

Reasons for Leakage of Chemical Fiber Spinning Metering Pump

Chemical polypropylene melt pump is used in synthetic filament system of a factory. Leakage occurs in the process of using chemical polypropylene melt pump. Specific inspection shows that: a. There are more melt oligomers leaking at coupling and coupling cover plate; B. There are degradable yellow melt in and out holes between pump body and pump seat. Causes of leakage of chemical polypropylene melt pump are as follows: 1. The pump base plate of chemical fiber spinning metering pump is thin, its

Application Range of High Temperature Melt Pump

Melt pump is a volumetric gear pump , which uses a pair of cylindrical gears (straight teeth, helical teeth, herringbone teeth) with external teeth to rotate relatively to transport high viscosity fluid. All gears and mating surfaces are grinded and assembly clearance is strictly controlled to obtain accurate flow rate. According to different common conditions of gear and pump body, ZB-B series adopts chromium-nickel alloy steel and high temperature tool steel; ZB-H series adopts imported CPM to

Melt Pump Melting Technology

Process 1: Melt Pump Hot Melt Extrusion This technology can treat polymer materials above their glass transition temperature, and promote the effective mixing of thermoplastic adhesives and/or polymers and active ingredients at the molecular level. Process II: Melt Pump Granulation Adhesive liquids are produced by heating, and one or more dry components in the formula become melts. At the end of the granulation stage, the mixture is cooled and the binder is solidified and melted. Technology 3/4:
