Lubricant
Multifunctional Lubricant Additives rau PVC Industries
| Internal lubricant TP-60 | |
| Qhov ntom | 0.86-0.89 g / cm3 |
| Refractive index (80 ℃) | 1.453-1.463 Nws |
| Viscosity (mPa.S, 80 ℃) | 10-16 |
| Acid nqi (mgkoh / g) | 10 |
| Tus nqi iodine (gl2/100g) | ＜1 |
Internal lubricants yog ib qho tseem ceeb additives nyob rau hauv PVC ua, raws li lawv ua lub luag haujlwm tseem ceeb hauv kev txo qis kev sib txhuam ntawm PVC molecule chains, uas ua rau qis qis viscosity. Ua polar nyob rau hauv qhov xwm txheej, lawv muaj kev sib raug zoo nrog PVC, kom ntseeg tau tias muaj txiaj ntsig zoo thoob plaws hauv cov khoom.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov roj nplua nyeem sab hauv yog lawv lub peev xwm los tswj cov pob tshab zoo txawm tias muaj ntau npaum li cas. Qhov pob tshab no yog qhov xav tau hauv cov ntawv thov uas qhov pom kev pom tseeb yog qhov tseem ceeb, xws li hauv cov khoom ntim pob tshab lossis cov lo ntsiab muag kho qhov muag.
Lwm qhov zoo dua yog tias cov roj nplaum sab hauv tsis zoo li exudate lossis tsiv mus rau qhov chaw ntawm PVC khoom. Cov cuab yeej uas tsis yog exudation no ua kom zoo dua vuam, gluing, thiab cov khoom luam tawm ntawm cov khoom kawg. Nws tiv thaiv qhov tawg paj thiab tswj kev ncaj ncees ntawm cov khoom, kom ntseeg tau tias kev ua tau zoo thiab zoo nkauj.
| Sab nrauv lubricant TP-75 | |
| Qhov ntom | 0.88-0.93g / cm3 |
| Refractive index (80 ℃) | 1.42-1.47 Nws |
| Viscosity (mPa.S, 80 ℃) | 40-80 : kuv |
| Acid nqi (mgkoh / g) | 12 |
| Tus nqi iodine (gl2/100g) | ＜2 |
Cov roj nplaum sab nraud yog cov khoom siv tseem ceeb hauv kev ua PVC, vim lawv ua lub luag haujlwm tseem ceeb hauv kev txo cov adhesion ntawm PVC thiab hlau nto. Cov lubricants no feem ntau tsis yog-polar nyob rau hauv cov xwm, nrog paraffin thiab polyethylene waxes feem ntau siv piv txwv. Kev ua tau zoo ntawm cov lubrication sab nraud feem ntau nyob ntawm qhov ntev ntawm cov saw hlau hydrocarbon, nws cov ceg, thiab muaj cov pab pawg ua haujlwm.
Thaum cov lubricants sab nraud muaj txiaj ntsig zoo hauv kev ua kom zoo dua qub, lawv cov tshuaj yuav tsum tau ua tib zoo tswj. Nyob rau hauv ntau npaum li cas, lawv yuav ua rau undesirable kev phiv xws li cloudiness nyob rau hauv lub kawg cov khoom thiab exudation ntawm lubricant rau saum npoo. Yog li, nrhiav kev tshuav nyiaj li cas hauv lawv daim ntawv thov yog qhov tseem ceeb los xyuas kom meej tias ob qho tib si txhim kho cov txheej txheem thiab cov khoom kawg uas xav tau.
Los ntawm kev txo cov adhesion ntawm PVC thiab hlau nto, lubricants sab nraud pab txhawb kev ua haujlwm zoo dua thiab tiv thaiv cov khoom los ntawm kev ua cov khoom siv. Qhov no txhim khu kev ua tau zoo ntawm cov txheej txheem tsim khoom thiab pab tswj kev ncaj ncees ntawm cov khoom kawg.
