Polymer mixing yog txhais tau tias yog ua kom muaj kev kho kom zoo dua lub polymer los yog polymer system los ntawm nqaij tov. Cov txheej txheem compounding yog los ntawm kev sib ntxiv ntawm ib qho ntxiv rau ntau txoj kev kho ntxiv, polymer alloys, thiab reactive mixing. Nws tau kwv yees tias feem ntau peb feem pua ntawm Teb Chaws Asmeskas cov qauv ntawm polymers yuav tsum muab coj los ua. Cov quav sib txawv tuaj yeem ua raws li kev ua tiav ntawm kev ua tiav ntawm daim ntawv thov zaum kawg. Cov khoom siv txuam nrog lwm cov khoom xws li cov ci ntsa iab thiab lub zog zoo heev, los yog kev txiav txim siab moldability thiab zoo nruj.
Qhov zoo sib xyaw polymer feem ntau yog pelletized rau ntxiv ua. Txawm li cas los, nws yog nce nthuav hauv kev lag luam los muab kev sib xyaw ua ke nrog tus txheej txheem tom ntej, xws li profile extrusion, kom tsis txhob rov ua dua lub polymer.
Folding mix
Muaj ntau hom khoom siv yaj khoom siv, los ntawm cov yob thiab batch mixers rau cov ntsia hlau ntsia hlau thiab sib tw twv sib tw. Nruam cov khoom sib txuas (extruder) yog cov khoom siv feem ntau siv vim nws muaj peev xwm muab cov khoom zoo ib yam thiab txo cov nqi khiav lag luam. Nws muaj ob hom kev tov: muab sib tov sib faib ua ke nyob rau hauv ib qho sib xyaw ua ke uas tsis siv high shear stress. Hom sib tov no hu ua kev sib tov sib xyaw lossis laminar tov.
Decentralized mixing tseem hu ua kev sib txuam sib luag, qhov twg siab tshee kev nyuaj yog siv los rhuav tshem cov cohesive solids. Piv txwv, thaum lub pob additive tawg lawm, qhov me me qhov hnyav yuav me dua.
Tov haujlwm ntau zaus yuav tsum muaj ob hom kev sib tov nyob hauv ib txoj kev.
