Cov roj nplua nyeem sab hauv yog qhov tseem ceeb ntxiv rau hauv PVC ua haujlwm, raws li lawv ua lub luag haujlwm tseem ceeb hauv PVC molecule chains, uas ua rau qis melt viscosity. Kev ua ncov qaumteb qabteb nyob rau hauv qhov, lawv nthuav tawm siab sib haum nrog PVC, kom muaj txiaj ntsig zoo rieting thoob plaws cov khoom siv.
Ib qho ntawm cov txiaj ntsig tau txais ntawm cov roj nplua nyeem sab hauv yog lawv lub peev xwm los tswj cov tau txais txiaj ntsig zoo txawm tias ntawm cov tshuaj siab. Qhov no pob tshab yog qhov tsim nyog hauv cov ntawv thov uas pom kev pom tseeb, xws li ntim cov iav lossis cov iav ci ntsa iab.
Lwm qhov txiaj ntsig yog tias cov roj nplua nyeem zoo li qub tsis zoo li exudate los yog tsiv teb tsaws rau saum npoo ntawm pvc cov khoom. Qhov no tsis yog exudation cov cuab yeej kom ntseeg tau qhov zoo vuam, gluing, thiab luam ntawv thaj chaw ntawm cov khoom kawg. Nws tiv thaiv saum npoo blooming thiab tswj kev ncaj ncees ntawm cov khoom siv, kom ua tau zoo ib yam thiab ua kom loog.

Lubricants sab nraud yog qhov tseem ceeb ntxiv rau hauv PVC ua haujlwm, raws li lawv ua lub luag haujlwm tseem ceeb hauv kev txo cov nplaum ntawm PVC thiab hlau. Cov roj nplua nyeem no feem ntau tsis yog-ncov qaumteb qab teb, nrog paraffin thiab polyethylene waxes ua piv txwv feem ntau siv cov piv txwv. Qhov ua tau zoo ntawm lubrication sab nraud raws li nyob ntawm qhov ntev ntawm hydrocarbon saw, nws lub xub ntiag, thiab muaj cov pab pawg ua haujlwm.
Thaum cov roj nplua nyeem muaj txiaj ntsig zoo hauv kev ua haujlwm ua tiav, lawv cov tshuaj yuav tsum ua tib zoo tswj hwm. Ntawm cov kev cuam tshuam ntau, lawv yuav ua rau kev mob siab phiv xws li cloudiness hauv cov khoom kawg thiab exudation ntawm cov roj nplua nyeem ntawm cov npoo. Yog li, nrhiav txoj cai tshuav hauv lawv daim ntawv thov yog qhov tseem ceeb los xyuas kom meej ob qho tib si txhim kho cov txheej txheem thiab cov khoom xav tau kawg.
Los ntawm kev txo cov nplaum ntawm PVC thiab hlau npoo, covricants sab nraud los kho cov khoom smoother thiab tiv thaiv cov khoom los ntawm kev ua cov khoom siv. Qhov kev txhim kho no ntawm kev ua haujlwm ntawm kev tsim khoom lag luam thiab pab tswj kev ncaj ncees ntawm cov khoom kawg.
