Isithambisi
Izithasiselo Zokugcoba Ezinemisebenzi Eminingi Zezimboni ze-PVC
| I-lubricant yangaphakathi TP-60 | |
| Ubuningi | 0.86-0.89 g/cm3 |
| Inkomba yokubukeza (80℃) | 1.453-1.463 |
| Ukuqina (mPa.S, 80℃) | 10-16 |
| Inani le-asidi (mgkoh/g) | 10 |
| Inani le-Iodine (gl2/100g) | 1 |
Izithambisi zangaphakathi ziyizithasiselo ezibalulekile ekucutshungulweni kwe-PVC, njengoba zidlala indima ebalulekile ekunciphiseni amandla okungqubuzana phakathi kwamaketanga ama-molecule e-PVC, okuholela ekuncibilikeni okuphansi. Njengoba ngokwemvelo ziyi-polar, zibonisa ukuhambisana okuphezulu ne-PVC, okuqinisekisa ukusabalala okuphumelelayo kuyo yonke into.
Enye yezinzuzo eziphawulekayo zama-lubricant angaphakathi yikhono lawo lokugcina ukucaca okuhle kakhulu ngisho noma kunezilinganiso eziphezulu. Lokhu kucaca kuyadingeka kakhulu ekusetshenzisweni lapho ukucaca kokubona kubalulekile khona, njengasezintweni zokupakisha ezicacile noma amalensi okukhanya.
Enye inzuzo ukuthi amafutha okugcoba angaphakathi awavami ukukhipha noma ukuthuthela ebusweni bomkhiqizo we-PVC. Le mpahla engakhiphi i-exudation iqinisekisa izakhiwo zokushisela, ukunamathelisa, kanye nokuphrinta ezilungiselelwe kahle zomkhiqizo wokugcina. Ivimbela ukuqhakaza kobuso futhi igcina ubuqotho bezinto ezibonakalayo, iqinisekisa ukusebenza okulinganayo kanye nobuhle.
| Igrisi yangaphandle TP-75 | |
| Ubuningi | 0.88-0.93 g/cm3 |
| Inkomba yokubukeza (80℃) | 1.42-1.47 |
| Ukuqina (mPa.S, 80℃) | 40-80 |
| Inani le-asidi (mgkoh/g) | 12 |
| Inani le-Iodine (gl2/100g) | 2 |
Izithambisi zangaphandle ziyizithasiselo ezibalulekile ekucutshungulweni kwe-PVC, njengoba zidlala indima ebalulekile ekunciphiseni ukunamathelana phakathi kwe-PVC nezindawo zensimbi. Lezi zithambisi aziyona i-polar ngokwemvelo, kanti i-paraffin kanye ne-polyethylene wax ziyizibonelo ezivame ukusetshenziswa. Ukusebenza kahle kokuthambisi kwangaphandle kuncike kakhulu ebudeni beketanga le-hydrocarbon, ukuhluma kwalo, kanye nokuba khona kwamaqembu asebenzayo.
Nakuba amafutha okugcoba angaphandle ewusizo ekwenzeni izimo zokucubungula zibe ngcono, umthamo wawo udinga ukulawulwa ngokucophelela. Uma usebenzisa imithamo ephezulu, angaholela emiphumeleni emibi engathandeki njengokufiphala komkhiqizo wokugcina kanye nokuphuma kwamafutha okugcoba ebusweni. Ngakho-ke, ukuthola ibhalansi efanele ekusetshenzisweni kwawo kubalulekile ukuqinisekisa ukuthi kuthuthukiswa ukucutshungulwa kanye nezakhiwo zomkhiqizo wokugcina ezifiselekayo.
Ngokunciphisa ukunamathelana phakathi kwe-PVC nezindawo zensimbi, amafutha angaphandle enza kube lula ukucubungula kahle futhi avimbele izinto ukuthi zinganamatheli emishinini yokucubungula. Lokhu kuthuthukisa ukusebenza kahle kwenqubo yokukhiqiza futhi kusiza ukugcina ubuqotho bomkhiqizo wokugcina.
