Ngaphandle kweemveliso ezimbalwa zerabha zokwenziwa, uninzi lweemveliso zerabha zokwenziwa, njengerabha yendalo, ziyinto enokutsha okanye enokutsha. Okwangoku, iindlela eziphambili ezisetyenziselwa ukuphucula i-flame retardancy kukongeza i-flame retardants okanye i-flame retardant fillers, kunye nokudibanisa kunye nokuguqula izinto ezivuthayo zomlilo. Kukho iintlobo ezininzi zetekhnoloji yokubuyiswa komlilo kwirabha:
1. Irabha ye-Hydrocarbon
Irabha ye-Hydrocarbon ibandakanya i-NR, i-SBR, i-BR, njl. Ukongeza iiretardants zomlilo yindlela ebalulekileyo yokuphucula ukubuyiswa komlilo werabha ye-hydrocarbon, kunye nefuthe le-synergistic ye-retardants ye-flame retardants isetyenziselwa ukuphucula ngakumbi i-flame retardancy effect. Nangona kunjalo, ingqalelo kufuneka ihlawulwe kwisiphumo esibi somthamo we-flame retardant kwiipropathi zemishini yerubha.
Yongeza izihluzi ze-inorganic retardant ezifana ne-calcium carbonate, udongwe, umgubo we-talcum, i-carbon emhlophe emnyama, i-Aluminiyam hydroxide, njl.njl. ukunciphisa umyinge wezinto eziphilayo ezinokutsha. I-calcium carbonate kunye ne-nitrogen alumina zineempembelelo ze-endothermic xa zibolile. Le ndlela iya kunciphisa iimpawu ezithile zomzimba kunye noomatshini bezinto zerabha, kwaye inani lokuzaliswa akufanele libe likhulu kakhulu.
Ukongeza, ukwandisa ukuxinana kwe-rubber kunokunyusa i-oxygen index. Ngoko ke, inokuphucula ukuchithwa komlilo werabha. Oku kunokuba ngenxa yokwanda kweqondo lokushisa lokuchithwa kwe-thermal yezinto zerabha. Le ndlela isetyenziswe kwirabha ye-Ethylene propylene
2. Irabha eneHalogenated
I-rubber ye-halogenated iqulethe izinto ze-halogen, kunye nesalathisi se-oksijini ngokubanzi phakathi kwe-28 kunye ne-45, kunye ne-oxygen index ye-FPM ide idlule i-65. Iphakamileyo umxholo we-halogen kwi-rubber ye-halogenated, iphakamileyo ye-oxygen index yayo. Olu hlobo lwerabha ngokwalo lunelangatye eliphezulu lokungakhathali kwaye luzicima xa luvutha. Ke ngoko, unyango lwayo lokubuyiswa komlilo lulula kunerabha ye-hydrocarbon. Ukuphucula ngakumbi i-flame retardancy ye-rubber ye-halogenated, indlela yokongeza i-flame retardants ngokuqhelekileyo yamkelwa.
3. Irabha yeHeterochain
Olona hlobo lumele kakhulu lwerabha kolu luhlu luyirubha ye-dimethyl abicah, enesalathisi se-oksijini malunga ne-25. Iindlela ezisetyenziswayo ze-flame retardant kukunyusa izinga lokushisa lokubola kwe-thermal, ukwandisa intsalela ngexesha lokubola kwe-thermal, kunye nokunciphisa izinga lokuvelisa. iigesi ezinokutsha.
