Iimveliso zerabha zisekwe kwirabha ekrwada kwaye zongezwe ngexabiso elifanelekileyo leejenti ezidibanisayo.…
1.Irabha yendalo okanye yokwenziwa ngaphandle kwee-agent ezixutywayo okanye ngaphandle kwe-vulcanization ibizwa ngokudibeneyo njengerabha ekrwada.Irabha yendalo ineempawu ezintle ezibanzi, kodwa imveliso yayo ayinakuhlangabezana neemfuno zeshishini, kwaye ayinakuhlangabezana neemfuno ezithile zokusebenza, ngoko ke zininzi izicelo zerabha yokwenziwa.…
I-ejenti yokudibanisa Ukuze kuphuculwe kwaye kuphuculwe iimpawu ezahlukeneyo zeemveliso zerabha, into eyongeziweyo ibizwa ngokuba yi-agent edibanisayo.Ii-agent ezidibanisa ikakhulu ziquka ameva, izihluzi, i-vulcanization accelerators, iiplasticizers, i-anti-aging agents kunye nee-agent ezikhupha amagwebu.
① Indima ye-agent ye-vulcanizing ifana ne-ejenti yokunyanga kwiiplastiki ze-thermosetting.Yenza i-rubber ye-molecular chain chain chain chain chain, ngokufanelekileyo i-cross-linked, kwaye ibe yisakhiwo sothungelwano, ngaloo ndlela iphucula i-mechanical and physical properties of the rubber.I-sulfide esetyenziswa ngokuqhelekileyo yisulfure kunye ne-sulfide.…
② Isigcwalisi kukuphucula iipropathi zomatshini zerubha, njengamandla, ubunzima, ukumelana nokunxiba kunye nokuqina.Ezona zigcwalisiweyo zisetyenziswa ngokuqhelekileyo yikhabhoni emnyama kunye nelaphu, iifayibha, kunye neengcingo zetsimbi okanye iibradi zetsimbi njengezixhobo zesakhelo.Ukongeza izihluzi kunokunciphisa inani lerabha eluhlaza kunye nokunciphisa ixabiso lerabha.…
③ Ezinye ii-agent ezidityanisiweyo zokuvuza i-vulcanization i-accelerators inokukhawulezisa inkqubo ye-vulcanization kwaye iphucule umphumo we-vulcanization;iiplasticizers zisetyenziselwa ukunyusa iplastiki yerabha kunye nokuphucula inkqubo yokubumba;i-antioxidants (i-antioxidants) isetyenziselwa ukuthintela okanye ukulibazisa ukuguga kwerabha.
2.Iimpawu kunye nokusetyenziswa kweemveliso zerabha
Iimveliso zerabha zineempawu ze-elasticity ephezulu, ukomelela okuphezulu, amandla aphezulu kunye nokumelana nokunxiba okuphezulu.I-modulus yayo e-elastic iphantsi kakhulu, kuphela i-MPa eyi-1-10, kwaye i-deformation yayo ye-elastic inkulu kakhulu, ukuya kwi-100% ukuya kwi-1000%.Inokuguquguquka okugqwesileyo kunye nomthamo wokugcina amandla.Ukongeza, inokumelana nokunxiba kakuhle, ukugquma kwesandi, ukudambisa kunye nokugquma.Nangona kunjalo, irabha ayinakuxhathisa ubushushu kunye nokumelana nokubanda (incangathi kumaqondo obushushu aphezulu, inkunkqeke xa ibekwe kwingqele), kwaye iya kunyibilika kwizinyibilikisi.…
Kumashishini, irabha ingasetyenziselwa ukwenza amatayara, i-static kunye ne-dynamic seal, i-vibration damping kunye ne-anti-vibration parts, amabhanti okuhambisa, amabhanti okuhambisa kunye nemibhobho, iingcingo, iintambo, izixhobo zokugquma umbane kunye neendawo zokuqhawula.
