Kauj ruam thawj zaug ntawm kev sib tov yog tswj cov ntsiab lus ntawm txhua yam khoom xyaw thiab qhov kub ntawm qhov ci, yog li qhov nyuaj thiab cov khoom xyaw tuaj yeem ruaj khov. Tom qab sib tov, vim tias cov colloid tseem muaj cov khoom tsis huv thiab tsis sib xws, nws yuav tsum tau lim. Ntxiv nrog rau kev ua kom ntseeg tau tias cov colloid tsis muaj cov khoom tsis huv, lub lim kuj yuav tsum xyuas kom meej tias cov roj hmab roller tuaj yeem raug kev nyuaj siab sib xws thaum lub sijhawm ua haujlwm. Kauj ruam ntawm kev ua cov roj hmab rollers thiab lim yog qhov tseem ceeb tshwj xeeb rau cov tshuab luam ntawv ceev ceev, yog li tiv thaiv kev nthuav dav lossis kev cog lus los ntawm ntau yam laj thawj.
Tom qab ntawd lub log roj hmab kev lag luam raug cua sov, nias thiab vulcanized kom ruaj khov lub plasticizer, yog li thaum cov roj hmab ntsws thaum siv, qhov ntsws tuaj yeem txo qis kom tsawg kawg nkaus. Cov txheej txheem kho tuaj yeem ua rau nws mos thiab ruaj khov yam tsis poob nws qhov mos, thiab thaum kawg tuaj yeem hloov cov kua mem zoo dua.
Qhov kawg yog sib tsoo thiab polishing. Tsis tas yuav tsum muaj qhov kub tas li rau ob kauj ruam no. Txwv tsis pub, qhov kub qis dhau, nws yooj yim ua rau brittle hauv zos, thiab qhov kub siab dhau. Qhov chaw ntawm cov roj hmab roller kev lag luam feem ntau yuav carbonization, thiab qhov tshwm sim ntawm kev tev tawm tshwm sim thaum luam ntawv, uas yuav ua rau qhov zoo ntawm cov roj hmab roller poob qis, tsis muaj nws cov yam ntxwv zoo, thiab tsis tuaj yeem hloov pauv kua mem zoo. , Ua rau muaj pov tseg. Ob kauj ruam kawg no yog qhov tseem ceeb rau kev txiav txim siab qhov zoo ntawm cov roj hmab roller. Txawm hais tias qhov chaw ntawm cov roj hmab roller kev lag luam zoo li du, tseem muaj ntau qhov tsis sib xws me me ntawm qhov chaw. Sib tsoo thiab polishing yog ua kom cov roj hmab roller meej dua hauv qhov loj me, du nto, zoo dua kev hloov pauv kua mem, thiab zoo dua luam ntawv.
