Irabha ye-Nitrile butadiene (NBR) kunye ne-polyvinyl chloride (PVC) zizinto ezimbini ezisetyenziswa kakhulu kwishishini lokufakelwa kwezinto, ingakumbi kwizicelo zombane kunye nobushushu. Iimpawu zazo ezikhethekileyo zizenza zilungele iindawo ezahlukeneyo, kodwa ukusebenza kwezi zinto zokufakelwa izinto kunokwahluka kakhulu ngokuxhomekeke kwinkqubo yokwenziwa. Ukuqonda impembelelo yeendlela ezahlukeneyo zokwenza izinto kwindlela esebenza ngayo ukufakelwa kwezinto ze-NBR/PVC kubalulekile kubavelisi nakubasebenzisi bokugqibela.
Iimpawu zobushushu zezinto ze-NBR/PVC zixhomekeke kakhulu ekuqhubeni kwazo ubushushu, amandla e-dielectric, kunye nokunyamezelana nezinto ezingqongileyo ezifana nokufuma kunye nokuguquguquka kobushushu. Ezi mpawu zichaphazeleka kukwenziwa kwezinto, izongezo, kunye neenkqubo ezithile ezisetyenziswa kwimveliso.
Enye yeenkqubo eziphambili zokwenza izinto ezichaphazela ukusebenza kwe-insulation yindlela yokwenza i-compound. Kweli nqanaba, ii-polymers ezisisiseko (i-nitrile rubber kunye ne-polyvinyl chloride) zixutywa nezinye izongezo ezahlukeneyo, kubandakanya ii-plasticizers, iziqinisi, kunye nezizalisi. Ukukhethwa kwezongezo kunye noxinzelelo lwazo kutshintsha kakhulu iipropati zobushushu nezombane zemveliso yokugqibela. Umzekelo, ukongeza ii-plasticizers ezithile kunokuphucula ukuguquguquka kunye nokunciphisa ukuqhuba kobushushu, ngelixa izizalisi ezithile zinokuphucula amandla oomatshini kunye nokuzinza kobushushu.
Enye inkqubo ephambili yokuvelisa yindlela yokukhupha okanye yokubumba esetyenziselwa ukubumba izinto zokukhusela. Ukukhupha kubandakanya ukucinezela umxube wezinto kwidayi ukuze kwenziwe imo eqhubekayo, ngelixa ukubumba kubandakanya ukugalela izinto kwindawo eyakhiweyo. Indlela nganye ibangela umahluko kubuninzi, ukufana, kunye nolwakhiwo lulonke lwezinto zokukhusela. Umzekelo, izinto zokukhusela ze-NBR/PVC ezikhutshiweyo zinokuba nokufana okungcono kunye nokungashukumi okuphantsi xa kuthelekiswa neemveliso ezibunjiweyo, ngaloo ndlela ziphucula ukusebenza kwazo kokukhusela.
Inkqubo yokufunxa idlala indima ebalulekileyo kwiipropati zokufunxa izinto ze-nitrile rubber/polyvinyl chloride (NBR/PVC). Ukufunxa, okwaziwa ngokuba yi-vulcanization, kubhekisa kwinkqubo yokufunxa iintambo ze-polymer ngokusebenzisa ubushushu kunye noxinzelelo, okubangela ukuba izinto zibe zizinzile kwaye zihlale ixesha elide. Ubude kunye nobushushu benkqubo yokufunxa buchaphazela iipropati zokugqibela zezinto zokufunxa. Ukufunxa okunganelanga kukhokelela ekufunxeni okungaphelelanga, ngaloo ndlela kunciphisa ukumelana nobushushu kunye namandla e-dielectric. Ngokwahlukileyo koko, ukufunxa kakhulu kubangela ukuba izinto zibe buthathaka kwaye ziqhekeke, ngaloo ndlela kunciphisa ukusebenza kwazo kokufunxa.
Ngaphezu koko, izinga lokupholisa emva kwemveliso lichaphazela ubukhristalo kunye nokwakheka kwezinto ze-NBR/PVC. Ukupholisa ngokukhawuleza kunokukhokelela ekwandeni kwezakhiwo ezingabonakaliyo, okunokuphucula ukuguquguquka kodwa kunokunciphisa uzinzo lobushushu. Kwelinye icala, izinga lokupholisa elicothayo linokukhuthaza ukwakheka kwekristale, okunokuphucula ukumelana nobushushu kodwa kunciphise ukuguquguquka.
Ngamafutshane, iipropati zokwambathisa izixhobo ze-NBR/PVC zichaphazeleka kakhulu ziinkqubo ezahlukeneyo zokuvelisa. Ukusuka ekudibaniseni nasekubumbeni ukuya ekupheliseni nasekupholiseni, inyathelo ngalinye kwinkqubo yemveliso litshintsha iipropati zobushushu nezombane zemveliso yokugqibela. Abavelisi kufuneka baqwalasele ngononophelo ezi zinto ukuze baphucule ukusebenza kokwambathisa izixhobo ze-NBR/PVC kwizicelo ezithile. Ngokukhula okuqhubekayo kwemfuno yezinto zokwambathisa ezisebenzayo, uphando oluqhubekayo kunye nophuhliso lwetekhnoloji yemveliso lubalulekile ekuphuculeni ukusebenza kwezisombululo zokwambathisa ze-NBR/PVC kwiindawo ezahlukeneyo.
