Nyob rau hauv teb yas ua, pvc (polyvinyl chloride) tau siv dav vim nws cov khoom siv lub cev thiab tus nqi zoo heev} ua hauj lwm zoo. Txawm li cas los xij, teeb meem xws li siab melt viscosity thiab fluidity fluidity yog nquag tshwm sim thaum xaiv lub sijhawm ua ntej, yog li xaiv tau meej mom thiab siv cov roj nplua nyeem yog qhov tseem ceeb. Kab lus no yuav ua ke los tshawb txog lub luag haujlwm tseem ceeb thiab cov ntsiab lus ntawm PVC lubricants.
Core Love of PVC Lubricts
Lub luag haujlwm tseem ceeb ntawm hom lubricants yog los kho cov kev sib txhuam thiab txo cov kev sib txhuam ntawm cov khoom siv thiab kev txhim kho cov khoom tsim tau thiab txhim kho cov khoom lag luam zoo. Raws li cov txheej txheem ntawm kev nqis tes ua, roj nplua nyeem tuaj yeem faib ua ob pawg: cov roj ntau lubricants thiab cov roj nplua nyeem sab nrauv. Sab hauv lubricants tsuas yog ua nyob ntawm PVC molecular chains kom txo kev sib deev; Lubricantobe sab nrauv yuav tsim ib txheej sib cais ntawm cov khoom thiab cov hlau saum npoo los txo cov adcesion. Hauv kev tsim tiag, ob qho kev tsim nyog tau siv rau hauv kev sib txuas ua tiav kom ua tiav cov nyhuv sib npaug.
Qhov kev paub tseem ceeb hauv kev xaiv thiab kev faib tawm
Cov kev xaiv ntawm lubricists yuav tsum tau nkag siab txog hom ntawm PVC cov khoom lag luam, ua cov tshuab ua haujlwm thiab cov khoom siv siv cov cuab yeej cuab tam. Piv txwv, hauv kev tsim cov roj nyoos pvc}}}}}}}}}}}}- kub kuj; Thaum cov roj fatty acid Ester Sab hauv lubricants tuaj yeem ua kom tiav tau cov kua txiv hmab txiv ntoo. Cov khoom siv mos muag tau muaj cov ntsiab lus zoo nkauj, yog li cov roj nplua nyeem nrog cov khoom siv zoo nrog cov tshuaj yooj yim kom tsis txhob muaj feem xyuam ntawm nag lossis daus.
Hais txog kev faib ua feem, kev lag luam feem ntau pom zoo pib ua ntu zus (xws li 0.1% ntawm tag nrho cov mis) thiab maj mam hloov kho rau lub xeev zoo tagnrho. Siv cov roj nplua ntau yuav ua rau txo qis hauv cov khoom siv cov khoom siv ntawm cov khoom lag luam, thaum siv tsis txaus yuav ua rau muaj kev kub ntxhov lossis khoom siv overheating.
Cov teeb meem thiab kev daws teeb meem
Thaum "swb" tshwm sim thaum ua kev sib npaug ntawm cov roj nplua nyeem sab nraud tuaj yeem tsim kev nce ntxiv; Yog tias muaj kev sib cav lossis dej nag lossis daus muaj nyob ntawm cov khoom, cov roj nplua nyeem yuav tsum tau txo lossis hloov nrog ntau ntau yam. Tsis tas li ntawd, lub viscosity hloov pauv ntawm cov kev sib txawv ntawm cov khoom sib txawv ntawm cov ntaub ntawv raw kuj tseem yuav cuam tshuam rau cov khoom siv lubrication lubrication. Nws raug nquahu kom ntsuas thiab nplua - ziab cov qauv.
Mastering daim ntawv thov tau ntawm PVC lubricants tuaj yeem tsis tsuas yog ua kom zoo rau cov txheej txheem ntau lawm, tab sis kuj txhim kho cov khoom lag luam zoo. Nrog rau cov kev tiv thaiv ib puag ncig ib puag ncig, cov roj nplua nyeem thiab cov roj nplua nyeem tsawg yuav dhau los ua qhov tseem ceeb ntawm kev lag luam hauv lub neej yav tom ntej.
