Butyl Rubber Bladders

I-butyl yerabha yesinyi ibhekisa kwingxowa yomoya evuthekayo ikakhulu eyenziwe ngerabha ye-butyl (IIR), ingakumbi irabha ye-butyl ene-halogenated (efana ne-chlorinated butyl CIIR okanye i-brominated butyl BIIR) njengomaleko ongangeni moya.
Isitshixo asikho kwimilo okanye kwisakhiwo se-airbag, kodwa kwi-airtightness yayo engenakulinganiswa, ephuma kwiimpawu ze-molecular structure ye-rubber ye-butyl ngokwayo.

I-Isobutylene I-Rubber ye-Isoprene yirabha yokwenziwa ebonakaliswe ngokucwangciswa okuqinileyo kwamakhonkco e-molecular kunye nomthamo omncinci wamahhala.

Ukungangeni moya okokugqibela:
Phakathi kwazo zonke iirubha, irabha ye-butyl ineyona ndawo isezantsi yokungena kwerhasi (malunga ne-1/10 yerabha yendalo kunye ne-1/6 yerabha ye-styrene butadiene). Oku kuthetha ukuba umoya kunzima kakhulu ukuvuza kancinane kwimathiriyeli yerabha ngokwayo.
Iingxowa zomoya zerabha ibutyl zinokugcina uxinzelelo oluzinzileyo ixesha elide ngaphandle kokunyuka kwamaxabiso rhoqo, nto leyo izenza ukuba zilungele usetyenziso olufuna ugcino lwexesha elide{0}}lokumila okusisigxina kunye noxinzelelo.

Ukusebenza okugqwesileyo kokudambisa:
I-friction yangaphakathi ye-butyl ye-rubber ye-molecular chain iphezulu ngexesha lokuhamba, elinokuthi liguqule ngokufanelekileyo amandla omatshini (amandla e-vibration) kumandla okushisa kunye nokuwachitha.
Inokufunxeka kakuhle okugqwesileyo kunye nokusebenza kwe-buffering, enokuthi icinezele ngokufanelekileyo ukungcangcazela kunye nokufunxa amandla empembelelo.

Ukumelana kakuhle neekhemikhali kunye nemozulu:
Inokumelana kakuhle neekhemikhali ezifana ne-asidi edibeneyo, i-alkali, kunye ne-phosphate ester hydraulic oils.
Inokumelana nokuguga kwe-ozone, ukuguga kwemozulu, kunye nokuguga kobushushu ({0}}ubushushu bokusebenzisa ixesha elide linokufikelela kwi-150℃okanye ngaphezulu).

Ukuqina okuphezulu kunye nokuqina okuphantsi:
Nangona ino-elasticity elungileyo, isantya sayo sokubuyela umva siyacotha, nto leyo enceda ukufunxa impembelelo kunokuba iphinde ibe nempembelelo.

Iingxowa zomoya zerabha ye-butyl zidla ngokuba zizakhiwo eziyintlanganisela, ezingenziwanga ngokupheleleyo ngerabha ye-butyl, ukulinganisa ukusebenza kunye neendleko:
Umaleko womgca wangaphakathi (umaleko ongangeni moya):yenziwe ngerabha ye-butyl ecocekileyo okanye i-halogenated butyl irabha, enoxanduva lokuqinisekisa ukungena komoya. Lo ngowona maleko ubalulekileyo.
Umaleko wamathambo (umaleko wokuqinisa):yenziwe ngeentambo eziphezulu-ezifana nenayiloni, ipolyester), inika amandla afunekayo kunye nokumelana noxinzelelo lokumelana nobuninzi boxinzelelo olwenziwa luxinzelelo lwangaphakathi.
Umaleko wangaphandle (umaleko okhuselayo):Ezinye iirubha ezinxibayo-ezikwaziyo ukumelana nemozulu (ezifana nerubha ye-chloroprene CR, EPDM) zingasetyenziselwa ukukhusela umaleko werabha we-butyl wangaphakathi kunye nomaleko wamathambo kumonakalo womatshini, i-ozone, kunye nemitha ye-ultraviolet.

Umzi mveliso weemoto - Inkqubo yokuNxinywa koMoya:

• Isicelo: Imithombo yomoya yeemoto, iibhasi, iilori, kunye nezithuthi zikaloliwe.
• Isizathu: Iingxowa zomoya zingundoqo wokunqunyanyiswa komoya kwaye zifuna uxinzelelo oluqhubekayo kunye nozinzo oluphezulu unyaka wonke. I-airtightness engalinganiyo ye-rubber ye-butyl iqinisekisa ukuba isithuthi sinokugcina imvume efanayo yomhlaba kunye namava okuqhuba ngokukhululekile phantsi kwemithwalo eyahlukeneyo, ngaphandle kwesidingo sokuba isithuthi siqalise rhoqo i-compressor yomoya yokuzaliswa komoya.

Ukufunxa okothusayo kunye nendawo yokuzahlula:

• Isicelo: Iqonga eliphezulu lokuchaneka kwezixhobo zokuchaneka, inkxaso yokwakha yodwa, izixhobo zoshishino zokothuka.
• Isizathu: Ukongeza kwiimfuno zokuxinana komoya, iimpawu zayo eziphezulu zokudambisa zinokufunxa ngokufanelekileyo amandla e-seismic okanye ii-vibrations eziveliswa kukusebenza kwesixhobo, ukuthintela i-resonance, kunye nokukhusela izixhobo ezichanekileyo (ezifana noomatshini be-lithography, ii-microscopes) okanye izakhiwo zokwakha.

Izixhobo zonyango nezemidlalo:

• Isicelo: Iingxowa zomoya zezonyango, iimatrasi zomoya ezichasene nezilonda zesilonda, izixhobo ezithile zokubuyisela kwisimo sangaphambili.
• Isizathu: Kuyimfuneko ukugcina uxinzelelo oluzinzileyo lwenkxaso ixesha elide ukukhusela izigulane, kwaye kukho iimfuno zokucoceka kunye ne-biocompatibility yezinto eziphathekayo (i-rubber ye-halogenated butyl isoloko ikhethwa).
• Kwiimeko ezifuna ukutywinwa okuphezulu kakhulu kunye nokugcinwa koxinzelelo:
• Isicelo: Iingxowa zomoya ezivaliweyo zoxinzelelo oluphezulu, iingxowa ezikhethekileyo zokugcina umoya.
• Isizathu: Irabha ye-butyl yeyona nto ikhethwayo kuyo nayiphi na imeko efuna uzinzo lwexesha elide{0}}loxesha elide phantsi koxinzelelo.

Ngokungangeni komoya okokugqibela, lolona khetho lukhethwayo kuzo zonke izicelo ezifuna inkxaso yoxinzelelo lwexesha elide{0}}oluzinzileyo, ngakumbi kwindawo yokunqunyanyiswa komoya wemoto apho ikwindawo eyongameleyo.
Iimpawu zayo eziphakamileyo zokudambisa ziyenza igqwese kwibala lokufunxa ukothuka kunye ne-buffer, icinezela ngokufanelekileyo ii-vibrations kunokubonelela ngenkxaso nje.
Ukukhetha ii-airbags zerabha ye-butyl kuthetha ukuba unelona nqanaba liphezulu leemfuno zozinzo loxinzelelo, ukuthembeka kokutywina, kunye nefuthe lokufunxa ukothuka kwenkqubo.

Iifayile ezishisayo: iibladders zerabha ye-butyl, iChina butyl irabha abavelisi, ababoneleli, umzi-mveliso
