Njengempahla eluhlaza yamathayi, irabha isho into enwebeka kakhulu ye-polymer ene-deformation ebuyela emuva.Iyanwebeka emazingeni okushisa asekamelweni, ingaveza ukonakala okukhulu ngaphansi kwesenzo samandla amancane angaphandle, futhi ingabuyela esimweni sayo sasekuqaleni ngemva kokususwa kwamandla angaphandle.Irabha iyi-polymer e-amorphous ngokuphelele.Izinga lokushisa layo lokushintsha kwengilazi liphansi futhi isisindo sayo samangqamuzana ngokuvamile sikhulu, sikhulu kunamakhulu ezinkulungwane.
Irabha ihlukaniswe yaba izinhlobo ezimbili: irabha yemvelo kanye nerabha yokwenziwa.Irabha yemvelo yenziwa ngokukhipha izinhlaka ezihlahleni zenjoloba, utshani benjoloba nezinye izitshalo;Irabha yokwenziwa itholakala nge-polymerization yama-monomer ahlukahlukene.
Sonke siyazi ukuthi ukubumba irabha kunezidingo zokushisa eziphezulu.Ngokuvamile, ukuze kuqinisekiswe umphumela omuhle wokubunjwa kwenjoloba, amafekthri enjoloba ngokuvamile asebenzisa amajeneretha omusi okushisa aphezulu ukuze ashise futhi alolonge irabha.
Njengoba irabha iyi-elastomer encibilika eshisayo, ipulasitiki iyi-elastomer encibilika ngokushisa futhi ebeka ukubanda.Ngakho-ke, izimo zokukhiqizwa kwemikhiqizo yerabha zidinga ukulungiswa okufanelekile kwezinga lokushisa kanye nomswakama nganoma yisiphi isikhathi, ngaphandle kwalokho umehluko wekhwalithi yomkhiqizo ungase ube khona.Ijeneretha yesitimu idlala indima ebalulekile kulokhu.
Noma ubani oye wathintana ne-raber uyazi ukuthi i-rubber ngokwayo idinga ukusekelwa kokushisa okuphezulu ukuze ibumbe, futhi lapho wenza imikhiqizo yenjoloba, kuyadingeka futhi ukusebenzisa amapulasitiki ashisayo ancibilika futhi abandayo, okudinga ukulungiswa kwezinga lokushisa ngesikhathi sokukhiqiza.Ijeneretha yesitimu ingadlala indima kule nqubo.Lo mkhiqizo owenziwe ngokwezifiso umenzi ungafinyelela ukulawula okuhlakaniphile futhi ungalungisa izinga lokushisa nomswakama ngokuvumelana nezinto ezihlukahlukene, ngaleyo ndlela wenze izinga lokukhiqiza lemikhiqizo yenjoloba libe phezulu.
Ijeneretha yesitimu ye-Nobeth ingaqhubeka nokukhipha isitimu esinezinga eliphezulu lokushisa ngezinga lokushisa elifinyelela ku-171°C, elifaneleka ngokugcwele ukukhiqizwa kwemikhiqizo yenjoloba.
