Iimveliso zerabha zisekelwe ngerabha eluhlaza kwaye zongezwa ngobungakanani obufanelekileyo bezinto ezidityanisiweyo. …
1.Irabha yendalo okanye eyenziweyo ngaphandle kwezinto ezidityanisiweyo okanye ngaphandle kwe-vulcanization ibizwa ngokuba yirabha eluhlaza. Irabha yendalo ineempawu ezilungileyo ezibanzi, kodwa imveliso yayo ayinakuhlangabezana neemfuno zoshishino, kwaye ayinakuhlangabezana neemfuno ezithile zokusebenza ezikhethekileyo, ngoko ke kukho iindlela ezininzi zokusetyenziswa kwerabha eyenziweyo. …
I-Compound agent Ukuze kuphuculwe kwaye kuphuculwe iipropati ezahlukeneyo zeemveliso zerabha, into eyongeziweyo ibizwa ngokuba yi-compound agent. Ii-compound agents ziquka ikakhulu i-vulcanization thorns, i-fillers, i-vulcanization accelerators, i-plasticizers, ii-anti-aging agents kunye nee-foam agents.
① Indima ye-agent ye-vulcanizing ifana ne-agent ye-curing kwi-thermosetting plastics. Yenza imixokelelwane ye-molecular yerabha yenze imixokelelwane ethe tye, edibeneyo ngokufanelekileyo, kwaye ibe yisakhiwo senethiwekhi, ngaloo ndlela iphucula iipropati zoomatshini nezomzimba zerabha. I-sulfide esetyenziswa rhoqo yi-sulfur kunye ne-sulfide. …
② Isizalisi senzelwe ukuphucula iipropati zerabha, ezinje ngamandla, ubulukhuni, ukumelana nokuguguleka kunye nokuqina. Ezona zizalisi zisetyenziswa kakhulu yi-carbon black kunye neendwangu, imicu, kwaneentambo zesinyithi okanye ii-braids zesinyithi njengezinto zokwakha. Ukongeza izizalisi kunokunciphisa ubungakanani berabha eluhlaza kwaye kunciphise iindleko zerabha. …
③ Ezinye izinto ezidityanisiweyo ezisebenzisa i-vulcanization accelerators zinokukhawulezisa inkqubo ye-vulcanization kwaye ziphucule isiphumo se-vulcanization; ii-plasticizers zisetyenziselwa ukwandisa i-plasticity yerabha kunye nokuphucula ukusebenza kwenkqubo yokubumba; ii-antioxidants (ii-antioxidants) zisetyenziselwa ukuthintela okanye ukulibazisa ukuguga kwerabha.
2.Iimpawu kunye nokusetyenziswa kweemveliso zerabha
Iimveliso zerabha zineempawu zokuthamba okuphezulu, ukuqina okuphezulu, amandla aphezulu kunye nokumelana nokuguguleka okuphezulu. Imodulus yayo ethambileyo iphantsi kakhulu, yi-1-10 MPa kuphela, kwaye ukuguquguquka kwayo okuthambileyo kukhulu kakhulu, ukuya kuthi ga kwi-100% ukuya kwi-1000%. Inokuguguleka okuhle kakhulu kunye namandla okugcina amandla. Ukongeza, inokumelana nokuguguleka okuhle, ukuthintela isandi, ukudambisa kunye nokuthintela. Nangona kunjalo, irabha inokumelana nokushushu okubi kunye nokumelana nokubanda (inamathela kumaqondo obushushu aphezulu, iyaphuka xa ibekwe kwindawo ebandayo), kwaye iya kunyibilika kwizinyibilikisi. …
Kwishishini, irabha ingasetyenziselwa ukwenza amatayara, izitywino ezingashukumiyo nezitshintshayo, iindawo zokudambisa ukungcangcazela kunye nezokuthintela ukungcangcazela, iibhanti zothumelo, iibhanti zokuhambisa kunye nemibhobho, iingcingo, iintambo, izixhobo zokukhusela umbane kunye neendawo zeebhuleki.
