Okokugcoba
Izithasiselo Ezisebenza Kakhulu Zokuthambisa zePVC Industries
| I-lubricant yangaphakathi TP-60 | |
| Ukuminyana | 0.86-0.89 g/cm3 |
| Inkomba ye-Refractive (80℃) | 1.453-1.463 |
| I-Viscosity (mPa.S, 80℃) | 10-16 |
| Inani le-Acid (mgkoh/g) | ＜10 |
| Inani le-Iodine (gl2/100g) | ＜1 |
Izithambisi zangaphakathi ziyizithasiselo ezibalulekile ekucutshungulweni kwe-PVC, njengoba zidlala indima ebalulekile ekwehliseni amandla okungqubuzana phakathi kwamaketanga e-molecule ye-PVC, okuholela ekuncipheni kwe-viscosity ephansi. Njengoba i-polar ngokwemvelo, ibonisa ukuhambisana okuphezulu ne-PVC, iqinisekisa ukuhlakazeka okuphumelelayo kuyo yonke into.
Enye yezinzuzo eziphawulekayo zezithambisi zangaphakathi yikhono lazo lokugcina izinto ezingafihli lutho ngisho nangemithamo ephezulu. Lokhu kungafihli kuhle kakhulu ezinhlelweni zokusebenza lapho ukucaca okubonakalayo kubalulekile, njengakuzinto zokupakisha ezibonisa ngale noma amalensi okubona.
Enye inzuzo ukuthi izinto zokugcoba zangaphakathi azijwayele ukukhipha noma ukuthuthela phezulu komkhiqizo we-PVC. Le ndawo engeyona i-exudation iqinisekisa ukushisela okulungiselelwe, ukunamathisela, nokuphrinta komkhiqizo wokugcina. Ivimbela ukuqhakaza kwendawo futhi igcine ubuqotho bezinto ezibonakalayo, iqinisekisa ukusebenza okungaguquki kanye nobuhle.
| I-lubricant yangaphandle i-TP-75 | |
| Ukuminyana | 0.88-0.93 g/cm3 |
| Inkomba ye-Refractive (80℃) | 1.42-1.47 |
| I-Viscosity (mPa.S, 80℃) | 40-80 |
| Inani le-Acid (mgkoh/g) | ＜12 |
| Inani le-Iodine (gl2/100g) | ＜2 |
Izithambisi zangaphandle ziyizithasiselo ezibalulekile ekucutshungulweni kwe-PVC, njengoba zidlala indima ebalulekile ekwehliseni ukunamathela phakathi kwe-PVC nezindawo zensimbi. Lawa mafutha ngokuyinhloko awawona ama-polar ngokwemvelo, kanti upharafini nama-polyethylene wax okuyizibonelo ezisetshenziswa kakhulu. Ukusebenza kokugcoba kwangaphandle kuncike kakhulu kubude beketango le-hydrocarbon, i-branching yalo, nokuba khona kwamaqembu asebenzayo.
Nakuba izithambisi zangaphandle zinenzuzo ekuthuthukiseni izimo zokucubungula, umthamo wazo udinga ukulawulwa ngokucophelela. Ngemithamo ephezulu, ingaholela emiphumeleni engathandeki engathandeki njengokufiphala emkhiqizweni wokugcina kanye nokukhipha okokugcoba phezulu. Ngakho-ke, ukuthola ibhalansi efanele ekusetshenzisweni kwabo kubalulekile ukuze kuqinisekiswe kokubili ukucutshungulwa okuthuthukisiwe kanye nezakhiwo ezifiselekayo zomkhiqizo wokugcina.
Ngokunciphisa ukunamathela phakathi kwe-PVC nezindawo zensimbi, izinto zokugcoba zangaphandle zenza kube lula ukucutshungulwa okushelelayo futhi kuvimbele okokusebenza ukuthi kunamathele kumishini yokucubungula. Lokhu kuthuthukisa ukusebenza kahle kwenqubo yokukhiqiza futhi kusiza ukugcina ubuqotho bomkhiqizo wokugcina.
