Kenyelletso ea ts'ebetso ea WPC(hape e bitsoaLubricant bakeng sa WPC, kapamoemeli oa tokollo bakeng sa WPC) ke lubricant e inehetseng bakeng sa tlhahiso le ts'ebetso ea metsoako ea lehong-plastiki (WPC): Ntlafatsa ts'ebetso ea phallo ea ts'ebetso, ho ntlafatsa ponahalo ea lihlahisoa, ho netefatsa boleng ba lihlahisoa, ho fokotsa likhohlano lipakeng tsa metsoako ea polymer le mochini o sebetsang, thepa ea ho roala, 'me sebopeho sa extrusion se boreleli.Boleng batlatsetso ea lubricant bakeng sa WPCe na le tšusumetso e kholo bophelong ba ts'ebeletso ea hlobo, barrel le screw ka har'a ts'ebetso ea polasetiki ea lehong, matla a tlhahiso ea extruder, tšebeliso ea matla ts'ebetsong ea tlhahiso, pheletso ea lihlahisoa le ts'ebetso e tlase ea mocheso oa profiles.'Me haeba ho eketsa stearate ho thuso ea ho lokisa lehong ka MAH ho tla fokolisa phello ea ho kopanya ea maleic anhydride, motsoako oa crosslinking le ts'ebetso ea lubricant e tla fokotseha.

Khetho eatharollo ea lubricant bakeng sa WPCe nahanela litlhoko tse latelang:

E na le tumellano e ntle le resin ka mocheso o phahameng, e ka hlahisa phello e itseng ea polasetiki, e fokotsa matla a ho kopanya pakeng tsa limolek'hule ka resin, e fokolisa limolek'hule.

, khohlano pakeng tsa e mong le e mong, fokotsa viscosity e qhibilihisang ea resin, e ntlafatsa phallo ea ho qhibiliha, e khothalletsa ho thella ha likaroloana tsa resin.
