Peb txhua tus paub tias nyob rau hauv cov txheej txheem ntawm cua sov thiab melting molding, yas yuav raug thawb los ntawm mechanical quab yuam thiab agitated los ntawm shear quab yuam, yas thiab yas, yas thiab machinery yuav tsim ntau yam kev sib txhuam, kev sib txhuam yuav ua kom sov, thiab kev sib txhuam ntau dhau yuav tsim kev sib txhuam kub. , kom qhov kub ntawm cov txheej txheem yas tsis tuaj yeem raug xa tawm thiab qhov tshwm sim ntawm scorching thiab npuas tshwm sim.
Yog li, lubricants feem ntau yog ntxiv rau hauv cov txheej txheem yas los txo qhov kev nyiam ntawm cov khoom siv polymer, yog li txhim kho lawv cov fluidity, thiab txo cov adhesion ntawm cov khoom thiab cov adhesion ntawm plastics rau ib leeg. Ntxiv nrog rau kev txhim kho flowability, lubricants tseem tuaj yeem ua lub luag haujlwm ntawm cov neeg txhawb nqa yaj, cov tshuaj tiv thaiv thaiv, cov tshuaj tiv thaiv kab mob, cov neeg ua haujlwm plam, thiab lwm yam.
