Cov roj nplua nyeem sab hauv yog cov khoom siv tseem ceeb hauv kev ua cov PVC, vim lawv ua lub luag haujlwm tseem ceeb hauv kev txo cov kev sib txhuam ntawm cov saw hlau PVC, ua rau cov viscosity yaj qis dua. Vim tias lawv muaj cov yam ntxwv polar, lawv ua tau zoo nrog PVC, ua kom muaj kev sib kis zoo thoob plaws cov khoom.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov roj nplua nyeem sab hauv yog lawv lub peev xwm los tswj kom pom tseeb zoo txawm tias siv ntau npaum li cas los xij. Qhov kev pom tseeb no yog qhov xav tau heev rau cov ntawv thov uas qhov pom tseeb yog qhov tseem ceeb, xws li hauv cov ntaub ntawv ntim khoom pob tshab lossis cov iav tsom iav.
Lwm qhov zoo dua yog tias cov roj nplua nyeem sab hauv tsis nyiam exudate lossis tsiv mus rau qhov chaw ntawm cov khoom PVC. Qhov khoom tsis-exudation no ua kom muaj kev vuam zoo, gluing, thiab luam ntawv ntawm cov khoom kawg. Nws tiv thaiv kev tawg ntawm qhov chaw thiab tswj kev ncaj ncees ntawm cov khoom siv, ua kom muaj kev ua tau zoo thiab kev zoo nkauj.
| Cov roj nplua nyeem sab nraud TP-75 | |
| Qhov Ceev | 0.88-0.93 g/cm3 |
| Cov ntsuas kev hloov pauv (80 ℃) | 1.42-1.47 |
| Qhov khov (mPa.S, 80 ℃) | 40-80 |

Cov roj nplua nyeem sab nraud yog cov khoom ntxiv tseem ceeb hauv kev ua PVC, vim lawv ua lub luag haujlwm tseem ceeb hauv kev txo qhov kev sib txuas ntawm PVC thiab cov hlau. Cov roj nplua nyeem no feem ntau tsis yog polar, nrog rau paraffin thiab polyethylene waxes feem ntau siv piv txwv. Qhov ua tau zoo ntawm kev siv roj nplua nyeem sab nraud feem ntau nyob ntawm qhov ntev ntawm cov saw hydrocarbon, nws cov ceg, thiab qhov muaj cov pab pawg ua haujlwm.
Txawm hais tias cov roj nplua nyeem sab nraud muaj txiaj ntsig zoo rau kev ua kom zoo dua qub, lawv cov koob tshuaj yuav tsum tau tswj hwm kom zoo. Yog tias noj ntau dhau, lawv yuav ua rau muaj cov kev mob tshwm sim tsis zoo xws li ua rau cov khoom kawg tsis zoo thiab ua rau cov roj nplua nyeem tawm ntawm qhov chaw. Yog li, nrhiav qhov sib npaug zoo hauv lawv daim ntawv thov yog qhov tseem ceeb kom ntseeg tau tias ob qho tib si ua tau zoo dua thiab cov khoom kawg xav tau.
Los ntawm kev txo qhov kev sib txuas ntawm PVC thiab cov hlau, cov roj nplua nyeem sab nraud pab txhawb kev ua haujlwm kom du thiab tiv thaiv cov khoom kom tsis txhob lo rau cov khoom siv ua haujlwm. Qhov no ua rau kev ua haujlwm zoo dua thiab pab tswj kev ua haujlwm ntawm cov khoom kawg.
