Umzi-mveliso wethu ujongana nemveliso yerabha ye-butyl.Ngokudibanisa i-catalyst kwifomula, irabha iya kungena kwinqanaba elithile le-vulcanization reaction.Ngale ndlela, ikhonkco lemolekyuli yerabha yepolymer iyazinza ngakumbi, kwaye ukuxhathisa kobushushu obuphezulu berabha ye-butyl evuzayo kunokufikelela kwi-120 ℃ ukuya kuma-200 ℃.Emva kokugquma okanye ukukhupha irabha egqityiweyo kancinane, iya kusetyenziswa kwiindawo zokuvala amanzi kunye nokutywinwa kwemoto, kwaye iya kuhlala izinzile ngaphandle kokuhamba xa ubushushu bangaphandle bufikelela kwincopho.
Ngexesha elifanayo, ngovavanyo lokubamba i-viscosity, isisombululo se-viscosity sokubamba siya kuhlala isiqingatha seyure ngaphandle kokuma.
Kuphela kwinkqubo yokuxuba irabha ebonakalayo, ukuba i-colloid yobushushu obuphezulu kwi-80 ℃ ayihambi, umlinganiselo werabha ye-butyl kufuneka ube phezulu kakhulu, kodwa kwinkqubo yokusabela kweekhemikhali, umxholo werabha awufuni ukuba phezulu kakhulu. ukufezekisa ukusebenza kobushushu obuphezulu akuhambi, kwaye i-viscosity kunye ne-viscosity ibaluleke kakhulu!Oku kuya kunciphisa ezinye iindleko.
Ukuba unemeko yesicelo esikhethekileyo, udinga ukusebenza okuphezulu kwerabha ye-butyl, kwaye ufuna ukuba nexabiso elihle, nceda uqhagamshelane nathi nge-imeyile!
