Wisigqoko ukuvuvukala?
I-Vulcanization isho inqubo yemikhiqizo yenjoloba esabela ngamakhemikhali (efana nepayipi lerabha) enama-vulcanizing agents (afana nesibabule noma ama-sulphur oxides) ngaphansi kwezimo ezithile zokushisa nezimo zesikhathi ukuze kwakheke isakhiwo esixhumene kakhulu.Le nqubo ihlela kabusha izibopho zamakhemikhali phakathi kwama-molecule enjoloba, okwenza injoloba ibe namandla, iqine, futhi iyinikeze izici ezithile ezibonakalayo.
Izinzuzo zenjoloba eyenziwe nge-vulcanized:
Usizo lwe-Vulcanizationsirabha ukuze igcine isimo sayo sokuqalangenkathiimbangelaing irabha ukuze ishwabaneekuncipheni.Inqubo ye-vulcanization yenza irabha ibe lukhuni, iyenze ingabi lula ukuwohloka. Uma kuqhathaniswa nerabha engashiyiwe, irabha eshisiwe inezinzuzo ezilandelayo:
● Ukunwebeka okuhle kakhulu
● Ukumunca amanzi aphansi
● Ukumelana ne-oxidation ephezulu nokumelana nokugqoka
● Isivikelo sikagesi esihle kakhulu
● Ingazweli kuzincibilikisi zemvelo
I-Hose Vulcanization
I-Vulcanization iyinqubo ebalulekile evame ukusetshenziswa ekukhiqizeni nasekulungiseni amapayipi.Le nqubo idlulisela izakhiwo ezingcono zomzimba kanye nokuqina kwepayipi.
● I-Vulcanizationukwakha
Ngemvaisakhiwoipayipi lerabha, walifaka ethangini elikhulu le-steam vulcanization for high-temperature vulcanization, bese-keipayipi izokwakhiwangemva kokushiswa kwe-steam nokushisa.
● Ukusebenza okuthuthukisiwe
Amandla, ukuqina kanye nokumelana nokugqokwa kwerabha kungathuthukiswa ngokwenza i-vulcanization, iyenze iqine, inwebeke futhi ibe nokuqina okungcono, ukudabuka nokungagugi.
● Ukukhula kwesikhathi sokuphila
I-hose yenjoloba izothinteka yizinto ezihlukahlukene zangaphandle ngesikhathi sokusetshenziswa, njenge-oxygen, i-ozone, imisebe ye-ultraviolet nezinto zamakhemikhali.I-Vulcanization ingenza ungqimba lwerabha ecinene ecinene endaweni yepayipi, engathuthukisa ukumelana nokuguga kwepayipi futhi andise impilo yayo yesevisi.
Izinyathelo zokuphepha ze-vulcanization
● Ukulawula izinga lokushisa: Izinga lokushisa le-vulcanization kufanele lilawulwe ngaphakathi kwebanga elishiwo, ngaphandle kwalokho lizothinta ikhwalithi nempilo yesevisi yepayipi.
● Ukulawula ukucindezela: Kufanele kusetshenziswe ingcindezi ethile phakathi ne-vulcanization ukuze kuqinisekiswe ikhwalithi namandla amalunga epayipi.Ngakho-ke, kuyadingeka ukuqinisekisa ukusebenza okuvamile kwesistimu yokulawula ingcindezi ye-i-autoclave, kanye nokuqapha nokulungisa ingcindezi.
● Ukulawula isikhathi: Isikhathi sokwenza vulcanization kufanele silawulwe phakathi kwebanga elishiwo.Uma imfushane kakhulu, izodala ubumpofuukunamathela, futhi uma yinde kakhulu, izothinta ukusebenza kahle kokukhiqiza.
● Amazinga okusebenza: Abaqhubi badinga ukujwayelana nezinqubo zokusebenza zemishini, futhi basebenze ngendlela efanele njengoba kudingeka ukuze bagweme izingozi ngenxa yokusebenza okungafanele.
● Ukuvikela ukuphepha: Ngesikhathi senqubo yokubhebhetheka, ukuvikela ukuphepha kufanele kucatshangelweto vimbela izingozi, ukuqhuma nemililo.Ngesikhathi esifanayo, umoya omncane kanye nezinyathelo zokuzivikela kufanele zithathwe ukuze kugwenywe amagesi ayingozi namazinga okushisa aphezulu ekuthinteni opharetha.
