Irabha ye-Nitrile butadiene (NBR) kanye ne-polyvinyl chloride (PVC) yizinto ezimbili ezisetshenziswa kabanzi embonini yokufaka ugesi, ikakhulukazi ekusetshenzisweni kukagesi nokushisayo. Izakhiwo zabo eziyingqayizivele zibenza bafaneleke ezindaweni ezihlukahlukene, kodwa ukusebenza kwalezi zinto zokuvikela kungahluka kakhulu kuye ngokuthi inqubo yokukhiqiza. Ukuqonda umthelela wezindlela zokukhiqiza ezihlukene ekusebenzeni kokufakwa kwezinto ze-NBR/PVC kubalulekile kubo bobabili abakhiqizi nakubasebenzisi bokugcina.
Izakhiwo ze-insulation zezinto ze-NBR/PVC zincike kakhulu ekuziphatheni kwazo okushisayo, amandla e-dielectric, kanye nokubekezelela izici zemvelo ezifana nomswakama kanye nokushintshashintsha kwezinga lokushisa. Lezi zakhiwo zithintwa ukwakhiwa kwezinto, izithasiselo, nezinqubo ezithile ezisetshenziswa ekukhiqizeni.
Enye yezinqubo ezibalulekile zokukhiqiza ezithinta ukusebenza kwe-insulation yindlela yokuhlanganisa. Kulesi sigaba, ama-polymers ayisisekelo (irabha ye-nitrile ne-polyvinyl chloride) axubene nezithasiselo ezihlukahlukene, okuhlanganisa ama-plasticizers, ama-stabilizers, nama-filler. Ukukhethwa kwezithasiselo nokugxila kwazo kushintsha kakhulu izakhiwo ezishisayo nezikagesi zomkhiqizo wokugcina. Isibonelo, ukwengeza ama-plasticizers athile kungathuthukisa ukuguquguquka futhi kunciphise ukuqhutshwa kokushisa, kuyilapho izigcwalisi ezithile zingathuthukisa amandla emishini nokuzinza kokushisa.
Enye inqubo yokukhiqiza eyinhloko i-extrusion noma indlela yokubumba esetshenziselwa ukubumba izinto zokuvikela. Ukukhipha kuhilela ukucindezela ingxube yezinto ngedayizi ukuze kwakheke umumo oqhubekayo, kuyilapho ukubumba kuhilela ukuthela impahla endaweni eyakhiwe ngaphambili. Indlela ngayinye iholela ekuhlukeni kokuminyana, ukufana, kanye nesakhiwo sonke se-insulating material. Isibonelo, izinto zokuhlanganisa ze-NBR/PVC ezikhishiwe zingase zibe nokufana okungcono kanye ne-porosity ephansi uma kuqhathaniswa nemikhiqizo ebunjiwe, ngaleyo ndlela ithuthukise ukusebenza kwayo kokufakwa.
Inqubo yokwelapha idlala indima ebalulekile ekwakhekeni kokufakwa kwe-nitrile rubber/polyvinyl chloride (NBR/PVC). Ukwelapha, okubuye kwaziwe ngokuthi i-vulcanization, kubhekisela kunqubo yokuxhumanisa amaketanga e-polymer ngokusebenzisa ukushisa nokucindezela, okuholela ekutheni kube nezinto ezizinze futhi ezihlala isikhathi eside. Ubude nokushisa kwenqubo yokuphulukisa kuthinta izici zokugcina ze-insulation material. Ukwelashwa okunganele kuholela ekuxhumaneni okungaphelele, ngaleyo ndlela kunciphisa ukumelana nokushisa namandla e-dielectric. Ngokuphambene, ukuphulukisa ngokweqile kubangela ukuthi i-material ibe brittle futhi iqhekeke, ngaleyo ndlela inciphise ukusebenza kwayo kokuhlukanisa.
Ngaphezu kwalokho, izinga lokupholisa ngemva kokukhiqiza lithinta ukucwebezela kanye nokumila kwezinto ze-NBR/PVC. Ukupholisa okusheshayo kungase kuholele ekwandeni kwezakhiwo ze-amorphous, ezingathuthukisa ukuguquguquka kodwa zinganciphisa ukuzinza kokushisa. Ngakolunye uhlangothi, izinga lokupholisa elihamba kancane lingakhuthaza ukwenziwa kwekristalu, okungase kuthuthukise ukumelana nokushisa kodwa ngezindleko zokuvumelana nezimo.
Ngamafuphi nje, izici zokwahlukanisa zezinto ze-NBR/PVC zithinteka kakhulu yizinqubo ezihlukahlukene zokukhiqiza. Ukusuka ekuhlanganiseni nasekubumbeni kuye ekwelapheni nasekupholiseni, isinyathelo ngasinye enqubweni yokukhiqiza sishintsha izici ezishisayo nezikagesi zomkhiqizo wokugcina. Abakhiqizi kufanele bacabangele lezi zici ngokucophelela ukuze bathuthukise ukusebenza kokufakwa kwe-NBR/PVC kwezinhlelo zokusebenza ezithile. Ngokukhula okuqhubekayo kwesidingo sezinto zokufakelwa ezisebenza kahle kakhulu, ucwaningo oluqhubekayo nokuthuthukiswa kobuchwepheshe bokukhiqiza kubalulekile ekuthuthukiseni ukusebenza kwezixazululo ze-NBR/PVC zokufaka ezindaweni ezihlukahlukene.
