Cov txheej txheem no hu ua vulcanization ua cov roj hmab tsis muaj dej thiab lub caij ntuj no-pov thawj thiab qhib qhov rooj rau kev lag luam loj rau cov khoom siv roj hmab.
Puas yog vulcanized roj hmab txiv neej ua?
Ntxiv cov sulfur ntau dhau ua rau cov khoom nkig thiab tsis muaj zog hu ua ebonite. Man-made lossis hluavtaws roj hmab kuj tuaj yeem ua vulcanized, thiab cov txheej txheem zoo sib xws. Daim duab 1qhia tau hais tias yuav ua li cas rau roj hmab thaum cov hlua ntev ntawm polyisoprene yog cross-linked.
Yog cov roj hmab vulcanized siv niaj hnub no?
