Ukusetshenziswa
Enye yezinto ezisetshenziswa kakhulu i-acrylonitrile ukukhiqizwa kwe-polyacrylonitrile, i-polymer eguquguqukayo enokusimama okuhle kakhulu kokushisa nokumelana namakhemikhali. Le polymer isetshenziswa kabanzi embonini yendwangu ukudala izingubo ezisezingeni eliphezulu nezindwangu ezingamelana nezimo ezinzima zemvelo. Ukwengeza, i-acrylonitrile iyisakhiwo esibalulekile sokwakhiwa kwenjoloba ye-nitrile, eyaziwa ngokumelana kwayo okuhle kakhulu nowoyela namakhemikhali. Lokhu kukwenza kube ukukhetha okudumile ekukhiqizeni amagilavu, ama-seal kanye nama-gaskets asetshenziswa ezimbonini zezimoto, ezokunakekelwa kwezempilo kanye ne-petroleum.
I-Acrylonitrile nayo idlala indima ebalulekile ekukhiqizeni odayi nama-synthetic resins. Isakhiwo sayo samakhemikhali singasetshenziselwa ukwakha odayi abanempilo nabahlala isikhathi eside bezinhlelo zokusebenza ezisukela kwezindwangu kuya kweziyinki zokuphrinta. Ngaphezu kwalokho, ukusetshenziswa kwayo kuma-synthetic resins kwenza ukuthuthukiswa kwezinto ezihlala isikhathi eside nezingasindi zokwakhiwa, ifenisha nezimboni zezimoto. Lezi zimfanelo zenza i-acrylonitrile ibe yinhlanganisela ebalulekile yokwenza imikhiqizo edinga kokubili amandla kanye nobuhle.
Ngaphezu kwezicelo zayo ekukhiqizeni, i-acrylonitrile iphinde isetshenziswe embonini yezemithi. Yisakhiwo semithi ehlukahlukene, okuhlanganisa ama-antibiotics, ama-antihistamine kanye nezidakamizwa zomdlavuza. Ikhono layo lokusabela nezinye izinhlanganisela livumela ukuhlanganiswa kwama-molecule ayinkimbinkimbi anezakhiwo zokwelapha. Lokhu kugqamisa ukubaluleka kwe-acrylonitrile emkhakheni wezokwelapha, esiza ekuthuthukisweni kwezidakamizwa ezisindisa ukuphila.
Ekuphetheni, i-acrylonitrile iyinhlanganisela ebalulekile eye yashintsha izimboni ezihlukahlukene. Naphezu kokuvutha kwayo kanye nezingozi ezingase zibe khona, ukusetshenziswa kwayo ekukhiqizeni i-polyacrylonitrile, irabha ye-nitrile, odayi, ama-synthetic resin, kanye nemithi kuyenza ibe yingxenye ebalulekile yokukhiqiza yesimanje. Noma ngabe yenza izindwangu ezisebenza kahle kakhulu, ama-synthetics aqinile noma imithi esindisa impilo, i-acrylonitrile idlala indima ebalulekile ekulolongeni umhlaba esiphila kuwo namuhla.
