Imikhiqizo yenjoloba isekelwe kwirabha eluhlaza futhi yengezwa ngenani elifanele lezinto ezihlanganisayo.…
1.Irabha yemvelo noma yokwenziwa ngaphandle kwama-ejenti ahlanganisiwe noma ngaphandle kwe-vulcanization ibizwa ngokuhlangene ngokuthi irabha eluhlaza.Irabha yemvelo inezici ezinhle ezibanzi, kodwa okukhiphayo akukwazi ukuhlangabezana nezidingo zemboni, futhi ayikwazi ukuhlangabezana nezidingo ezithile zokusebenza okukhethekile, ngakho-ke ziningi izinhlelo zokusebenza zenjoloba yokwenziwa.…
I-ejenti ehlanganisayo Ukuze kuthuthukiswe futhi kuthuthukiswe izici ezihlukahlukene zemikhiqizo yenjoloba, into engeziwe ibizwa ngokuthi i-ejenti ehlanganisayo.Ama-compounding agents ikakhulukazi ahlanganisa ameva avuvuzayo, izigcwalisi, ama-accelerators e-vulcanization, amapulasitiki, ama-anti-aging agents kanye namagwebu.
① Indima ye-ejenti ye-vulcanizing ifana ne-ejenti elaphayo kumapulasitiki we-thermosetting.Yenza amaketanga erabha yamangqamuzana akhe amaketanga avundlile, axhunywe ngokufanele, futhi abe isakhiwo senethiwekhi, ngaleyo ndlela athuthukise izakhiwo zemishini nezomzimba zenjoloba.I-sulfide evame ukusetshenziswa yisulfure ne-sulfide.…
② Isigcwalisi siwukuthuthukisa izakhiwo zenjoloba ezisebenza ngomshini, njengamandla, ubulukhuni, ukumelana nokugqoka kanye nokuqina.Izigcwalisi ezisetshenziswa kakhulu yikhabhoni emnyama nezindwangu, imicu, ngisho nezintambo zensimbi noma amagoda ensimbi njengezinto zohlaka.Ukwengeza ama-filler nakho kunganciphisa inani lerabha eluhlaza futhi kunciphise izindleko zenjoloba.…
③ Amanye ama-ejenti ahlanganisayo ama-accelerator e-vulcanization angasheshisa inqubo ye-vulcanization futhi athuthukise umphumela we-vulcanization;ama-plasticizers asetshenziselwa ukwandisa ipulasitiki yenjoloba futhi athuthukise ukusebenza kwenqubo yokubumba;ama-antioxidants (ama-antioxidants) asetshenziselwa ukuvimbela noma ukubambezela ukuguga kwerabha.
2.Izici kanye nokusetshenziswa kwemikhiqizo yenjoloba
Imikhiqizo yenjoloba inezici zokunwebeka okuphezulu, ukuqina okuphezulu, amandla aphezulu kanye nokumelana nokugqoka okuphezulu.I-elastic modulus yayo iphansi kakhulu, i-MPa eyi-1-10 kuphela, futhi ukuguqulwa kwayo okunwebekayo kukhulu kakhulu, kuze kufike ku-100% kuya ku-1000%.Inokuguquguquka okuhle kakhulu namandla okugcina amandla.Ngaphezu kwalokho, inokumelana okuhle nokugqokwa, ukufakwa komsindo, ukuthambisa kanye nokufakwa.Kodwa-ke, irabha inokumelana nokushisa okungekuhle futhi imelana nokubanda (inamathela emazingeni okushisa aphezulu, ishwabene lapho ibekwe emakhazeni), futhi izoncibilika kuzincibilikisi.…
Embonini, irabha ingasetshenziselwa ukwenza amathayi, izigxivizo ezimile nezishintshashintshayo, izingxenye zokudambisa ukudlidliza kanye nezingxenye ezilwa nokudlidliza, amabhande okudlulisela, amabhande namapayipi okuthutha, izintambo, izintambo, izinto zokufaka ugesi kanye nezingxenye zamabhuleki.
