Isithambisi
Izithambisi zeZithambisi eziSebenzayo ezininzi kwiMizi-mveliso yePVC
| I-lubricant yangaphakathi TP-60 | |
| Uxinano | 0.86-0.89 g/cm3 |
| Isalathisi sokuhombisa (80℃) | 1.453-1.463 |
| Ukuxinana (mPa.S, 80℃) | 10-16 |
| Ixabiso le-asidi (mgkoh/g) | 10 |
| Ixabiso le-Iodine (gl2/100g) | 1 |
Ii-lubricants zangaphakathi zezona zinto zibalulekileyo ekucutshungulweni kwe-PVC, njengoko zidlala indima ebalulekileyo ekunciphiseni amandla okungqubana phakathi kwee-chain ze-molecule ze-PVC, nto leyo ebangela ukuba i-melt viscosity ibe sezantsi. Njengoko zi-polar ngokwendalo, zibonisa ukuhambelana okuphezulu ne-PVC, ziqinisekisa ukusasazeka ngempumelelo kuyo yonke into.
Enye yeenzuzo eziphawulekayo zezithambiso zangaphakathi kukukwazi kwazo ukugcina ukukhanya okugqwesileyo nokuba ziphezulu. Oku kubonakala kunqweneleka kakhulu xa kusetyenziswa apho ukucaca okubonakalayo kubalulekile, njengakwizinto zokupakisha ezibonakalayo okanye iilensi ze-optical.
Enye inzuzo kukuba izinto zokuthambisa zangaphakathi azinamdla wokukhupha okanye ukufuduka ziye kumphezulu wemveliso yePVC. Le mpawu yokungaphumi iqinisekisa ukuba imveliso yokugqibela iyakwazi ukuwelda, ukuncamathisela, kunye nokuprinta. Ithintela ukuqhakaza komphezulu kwaye igcina ukuthembeka kwezinto, iqinisekisa ukusebenza okuzinzileyo kunye nobuhle.
| Igrisi yangaphandle TP-75 | |
| Uxinano | 0.88-0.93 g/cm3 |
| Isalathisi sokuhombisa (80℃) | 1.42-1.47 |
| Ukuxinana (mPa.S, 80℃) | 40-80 |
| Ixabiso le-asidi (mgkoh/g) | 12 |
| Ixabiso le-Iodine (gl2/100g) | 2 |
Izithambisi zangaphandle zezona zongezo zibalulekileyo ekucutshungulweni kwePVC, njengoko zidlala indima ebalulekileyo ekunciphiseni ukunamathelana phakathi kwePVC kunye nomphezulu wesinyithi. Ezi zithambisi azinawo umbala omhlophe, kwaye iparafini kunye ne-polyethylene waxes ziyimizekelo esetyenziswa rhoqo. Ukusebenza kokuthambisi kwangaphandle kuxhomekeke kakhulu kubude betsheyini ye-hydrocarbon, ukwakheka kwayo, kunye nokubakho kwamaqela asebenzayo.
Nangona ii-lubricants zangaphandle ziluncedo ekwenzeni ngcono iimeko zokucubungula, i-dosage yazo kufuneka ilawulwe ngononophelo. Xa zisetyenziswa kakhulu, zinokukhokelela kwimiphumo emibi engathandekiyo efana nokufiphala kwimveliso yokugqibela kunye nokuphuma kwe-lubricant kumphezulu. Ke ngoko, ukufumana ibhalansi efanelekileyo ekusetyenzisweni kwazo kubalulekile ukuqinisekisa ukuba ziphucukile kwaye zineempawu ezifunekayo zemveliso yokugqibela.
Ngokunciphisa ukunamathelana phakathi kwePVC kunye nomphezulu wesinyithi, ii-lubricants zangaphandle zenza kube lula ukucubungula izinto kakuhle kwaye zithintele ukuba izinto zinganamatheli kwizixhobo zokucubungula. Oku kuphucula ukusebenza kakuhle kwenkqubo yokuvelisa kwaye kunceda ukugcina ukuthembeka kwemveliso yokugqibela.
