Ngaphandle kweemveliso zerabha ezimbalwa ezenziweyo, uninzi lweemveliso zerabha ezenziweyo, njengerabha yendalo, zizinto ezinokutsha okanye ezitshayo. Okwangoku, iindlela eziphambili ezisetyenziswayo ukuphucula ukucinywa komlilo kukongeza izinto ezithintela umlilo okanye izizalisi ezithintela umlilo, kunye nokudibanisa nokuguqula ngezinto ezithintela umlilo. Kukho iintlobo ezahlukeneyo zobuchwepheshe bokucinywa komlilo zerabha:
1. Irabha yeHydrocarbon
Irabha ye-hydrocarbon iquka i-NR, i-SBR, i-BR, njl. Irabha ye-hydrocarbon ngokubanzi ayinawo amandla okumelana nobushushu kunye nokungatshayi komlilo, kwaye uninzi lweemveliso zokubola ngexesha lokutsha ziigesi ezinokutsha. Ukongeza izinto ezithintela umlilo yindlela ebalulekileyo yokuphucula ukungatshayi komlilo kwerabha ye-hydrocarbon, kwaye isiphumo sokusebenzisana kwezinto ezithintela umlilo sisetyenziselwa ukuphucula ngakumbi isiphumo sokungatshayi komlilo. Nangona kunjalo, kufuneka kuqwalaselwe isiphumo esibi sobungakanani bezinto ezithintela umlilo kwiimpawu zerabha.
Yongeza izizalisi ezingafunekiyo zelangatye ezifana ne-calcium carbonate, udongwe, umgubo we-talcum, umnyama omhlophe wekhabhoni, i-aluminium hydroxide, njl.njl. ukunciphisa umlinganiselo wezinto eziphilayo ezinokutsha. I-calcium carbonate kunye ne-nitrogen alumina zinefuthe le-endothermic xa zibolile. Le ndlela iya kunciphisa iipropati ezithile zomzimba neze-mechanical zezinto zerabha, kwaye ubungakanani bokuzalisa akufuneki bube bukhulu kakhulu.
Ukongeza, ukonyusa uxinano lwerabha oludibanisayo kunokunyusa i-oxygen index yayo. Ke ngoko, kunokuphucula ukubambezeleka komlilo kwerabha. Oku kusenokubangelwa kukunyuka kobushushu bokubola kobushushu bezinto zerabha. Le ndlela isetyenzisiwe kwirabha ye-ethylene propylene.
2. Irabha ene-halogenated
Irabha yeHalogen iqulethe izinto zehalogen, kunye nesalathisi seoksijini ngokubanzi phakathi kwama-28 nama-45, kwaye isalathisi seoksijini seFPM sidlula nama-65. Okukhona umxholo wehalogen uphezulu kwirabha yehalogen, kokukhona isalathisi seoksijini siphezulu. Olu hlobo lwerabha ngokwalo lunokuthintela ilangatye okuphezulu kunye nokuzicima xa luvutha. Ke ngoko, unyango lwayo oluthintela ilangatye lulula kunerabha ye-hydrocarbon. Ukuphucula ngakumbi ukuthintelwa komlilo kwerabha yehalogen, indlela yokongeza izinto ezithintela ilangatye idla ngokusetyenziswa.
3. Irabha yeHeterochain
Uhlobo lwerabha olumele kakhulu kolu didi yirabha ye-dimethyl silicone, ene-oxygen index emalunga nama-25. Iindlela zokwenyani zokuthintela ilangatye ezisetyenziswayo kukunyusa ubushushu bayo bokubola, ukwandisa intsalela ngexesha lokubola kobushushu, kunye nokunciphisa isantya semveliso yeegesi ezitshayo.
