Imikhiqizo yerabha isekelwe ngerabha eluhlaza futhi yengezwe ngenani elifanele lezinto ezihlanganisayo. …
1.Irabha yemvelo noma yokwenziwa ngaphandle kwezinto ezihlanganisayo noma ngaphandle kwe-vulcanization ibizwa ngokuthi irabha eluhlaza. Irabha yemvelo inezakhiwo ezinhle eziphelele, kodwa umkhiqizo wayo awukwazi ukuhlangabezana nezidingo zemboni, futhi awukwazi ukuhlangabezana nezidingo ezithile zokusebenza ezikhethekile, ngakho-ke kunezindlela eziningi zokusebenzisa irabha yokwenziwa. …
I-compound agent Ukuze kuthuthukiswe futhi kuthuthukiswe izakhiwo ezahlukahlukene zemikhiqizo yerabha, into engeziwe ibizwa ngokuthi i-compound agent. Ama-compound agent afaka kakhulu ama-vorve e-vulcanization, ama-filler, ama-accelerator e-vulcanization, ama-plasticizer, ama-anti-aging agents kanye nama-foam agents.
① Indima ye-ejenti yokuhlanza ifana ne-ejenti yokwelapha kumapulasitiki okushisa. Yenza amaketanga e-molecular erabha akhe amaketanga avundlile, axhumene ngokufanele, futhi abe isakhiwo senethiwekhi, ngaleyo ndlela athuthukise izakhiwo ze-mechanical kanye nezomzimba zerabha. I-sulfide evame ukusetshenziswa yi-sulfur kanye ne-sulfide. …
② I-filler ihlose ukuthuthukisa izakhiwo zenjoloba, njengokuqina, ubulukhuni, ukumelana nokuguguleka kanye nokuqina. Ama-filler asetshenziswa kakhulu yi-carbon black kanye nezindwangu, imicu, ngisho nezintambo zensimbi noma ama-braids ensimbi njengezinto zokwakha uhlaka. Ukwengeza ama-filler kunganciphisa inani lenjoloba eluhlaza futhi kunciphise izindleko zerabha. …
③ Ezinye izinto ezihlanganisa izinto ezisheshisa i-vulcanization zingasheshisa inqubo ye-vulcanization futhi zithuthukise umphumela we-vulcanization; ama-plasticizer asetshenziselwa ukwandisa i-rubber plasticity kanye nokuthuthukisa ukusebenza kwenqubo yokubumba; ama-antioxidants (ama-antioxidants) asetshenziselwa ukuvimbela noma ukubambezela ukuguga kwe-rubber.
2.Izici kanye nokusetshenziswa kwemikhiqizo yerabha
Imikhiqizo yerabha inezimpawu zokuqina okuphezulu, ukuqina okuphezulu, amandla aphezulu kanye nokumelana nokuguguleka okuphezulu. I-modulus yayo eqina iphansi kakhulu, ingu-1-10 MPa kuphela, futhi ukuguquguquka kwayo okuqina kukhulu kakhulu, kufika ku-100% kuya ku-1000%. Inokuguquguquka okuhle kakhulu kanye nomthamo wokugcina amandla. Ngaphezu kwalokho, inokumelana okuhle nokuguguleka, ukuvimbela umsindo, ukudambisa kanye nokuvimbela ukushisa. Kodwa-ke, irabha inokumelana okuncane nokushisa kanye nokumelana nokubanda (iyanamathela emazingeni okushisa aphezulu, iyaphuka uma ibhekene nokubanda), futhi izoncibilika ezinyibilikisini. …
Embonini, irabha ingasetshenziswa ukwenza amathayi, izivalo eziguquguqukayo neziguquguqukayo, izingxenye zokudambisa ukudlidliza kanye nezingxenye ezilwa nokudlidliza, amabhande okudlulisa, amabhande okuhambisa kanye namapayipi, izintambo, izintambo, izinto zokuvikela ugesi kanye nezingxenye zamabhuleki.
