Problems solved by technology

The life of the compressor valve plate is low, which brings downtime loss and increases the maintenance burden, which is also a common problem that has plagued the compressor industry for a long time
Especially in the occasion of compressing corrosive gas, such as oil and natural gas containing hydrogen sulfide gas or hydrogen chloride gas compression production line, etc., the valve plate of metal material will go out of the line in advance, corrosion wear failure or corrosion fatigue fracture, resulting in production stoppage

Abstract

The invention relates to a PEEK (polyether ether ketone) composite material preparation method. The material is chopped carbon fiber / PTFE / PEEK composite material for a gas compressor valve sheet. The technical process for preparing the composite material is innovative in that: the PEEK material is enhanced through the filling of the complex of chopped carbon fiber and polytetrafluoroethylene; the wear resistance of the PEEK composite material is improved with polytetrafluoroethylene; the chopped carbon fiber / PTFE / PEEK composite material is subjected to blending extrusion with a double-screw extruder; and after traction, cooling and pelletizing, the modified PEEK composite material is obtained. In the field of gas compressor valve sheet, compared with traditional metal materials, the PEEK composite material has good high rigidity and high toughness, and also relatively high dimensional stability, wear resistance and fatigue resistance. Also, with the material, compressor efficiency can be improved, and compressor noise can be reduced.

Description

technical field [0001] The invention relates to the field of macromolecules, in particular to a method for preparing a PEEK composite material, which is mainly applied to valve plates of engineering machinery gas compressors. Background technique [0002] The valve plate is one of the most critical vulnerable parts of the gas compressor. The quality and performance of the valve plate determine the three major performances of the entire compressor unit, including reliability, compression efficiency and maintenance cycle. Especially the reliability problem is the primary function of the compressor valve plate on the large petrochemical production line. The short service life of compressor valves brings downtime losses and increases maintenance burden, which is also a common problem that has plagued the compressor industry for a long time. Especially in the occasion of compressing corrosive gas, such as oil and natural gas containing hydrogen sulfide gas or hydrogen chloride ...
