Iipropati
I-Chlorobutyl (CIIR) kunye ne-bromobutyl (BIIR) i-elastomers zi-copolymers ze-halogenated isobutylene (Cl, i-Br) kunye neemali ezincinci ze-isoprene ezibonelela ngeendawo ezingaxutywanga kwi-vulcanization.Ukuqaliswa kwe-bromine okanye i-chlorine kuphucula ukuchasana ne-ozone, isimo sezulu, iikhemikhali kunye nobushushu.Oku, nangona kunjalo, kuza ngeendleko zokugquma umbane kunye nokumelana nokufuma.
Zombini i-bromobutyl (BIIR) kunye ne-chlorobutyl (CIIR) inomqolo ogcweleyo we-isobutylene.Zombini ii-elastomers zineempawu ezininzi zerabha ye-butyl eqhelekileyo kubandakanya irhasi ephantsi kunye nokungenwa kokufuma, ukunyibilika okulungileyo kokungcangcazela, ubushushu obuphantsi beglasi, ukumelana nokuguga kunye nemozulu, kunye nokuguquguquka okubanzi.
Ukuqaliswa kweklorini okanye i-bromine kwandisa ukunamathela kwiirubha, kunye neentsimbi, kuphucula ukuhambelana neerubha ze-diene kwimixube, kwaye zibonelela ngamazinga aphezulu kakhulu okunyanga, oko kukuthi ixabiso eliphantsi lokunyanga liyafuneka.Ngaphaya koko, i-halogenated butyl inokudityaniswa kunye nenjongo eqhelekileyo ye-elastomers ephezulu-unsaturation, njengerabha yendalo, i-polybutadiene, kunye nerabha ye-styrene-butadiene, ngelixa igcina ubume bomqolo obugcweleyo.
Zombini iirubha ze-halogenated zineempawu ezifanayo kakhulu.I-Chlorine, nangona kunjalo, yonyusa ukusebenza kwakhona kweendawo zonyango ezikhokelela ekunyangeni ngokukhawuleza kunye nokuphuculwa kokuncamathela kwii-elastomer ezingafakwanga.
Usetyenziso
Zombini iirubha ze-butyl kunye ne-halobutyl zibonelela ngokugqwesileyo kogcino lwexabiso lokunyuka kwamaxabiso.Lukhetho olufanelekileyo lweetyhubhu zangaphakathi zeebhayisekile, iilori, kunye namatayara oshishino kunye nezolimo.Ngapha koko, iirubha ze-butyl ze-halogenated zezona zisetyenziswa kakhulu iirubha ze-butyl kumatayara angaphakathi angaphakathi.Iirubha ze-halobutyl zikwasetyenziselwa i-hoses, i-seal, i-membrane, i-tank linings, i-conveyor belts, iimpahla zokukhusela kunye neemveliso zabathengi, ezifana ne-ball bladders kwimpahla yezemidlalo.I-Halobutyl ngokuqhelekileyo lukhetho olufanelekileyo xa ukuxhathisa okulungileyo kwiikhemikhali, isimo sezulu kunye ne-ozone kufuneka.
Sebenzisa
Isetyenziswa kakhulu ekwenzeni iimveliso zerabha ezixhathisa ioyile, iigaskets ezixhathisa ioyile, iigaskets, imikhono, ukupakishwa okuthambileyo, ithumbu elibhetyebhetye, ukuprinta kunye nokudaya iirola zerabha, izixhobo zerabha yentambo, njl. njl. , inqwelomoya, i-petroleum, ukukopa kunye namanye amashishini.
