Chlorobutyl (CIIR) ndi bromobutyl (BIIR) elastomers ndi ma copolymers a halogenated isobutylene (Cl, Br) ndi kachulukidwe kakang'ono ka isoprene kamene kamapereka malo opanda unsaturated kuti vulcanization.Kuyambitsidwa kwa bromine kapena klorini kumathandizira kukana kwa ozoni, nyengo, mankhwala, ndi kutentha.Izi, komabe, zimabwera chifukwa cha kutsekemera kwa magetsi komanso kukana chinyezi.
Onse a bromobutyl (BIIR) ndi chlorobutyl (CIIR) ali ndi msana wodzaza wa isobutylene.Ma elastomer onsewa ali ndi zinthu zambiri za mphira wamba wa butyl kuphatikiza mpweya wochepa komanso kutulutsa chinyezi, kugwedera kwabwino, kutentha kwamagalasi otsika, kukana kukalamba ndi nyengo, komanso kusinthasintha kosiyanasiyana.
Kuyamba kwa klorini kapena bromine kumawonjezera kumamatira ku mphira, ndi zitsulo, kumapangitsa kuti mphira zizigwirizana ndi diene mu zosakaniza, ndipo zimapereka machiritso apamwamba kwambiri, mwachitsanzo, kutsika kochepa kwa mankhwala kumafunika.Kuphatikiza apo, halogenated butyl imatha kuphatikizidwa ndi ma elastomers amtundu wambiri, monga mphira wachilengedwe, polybutadiene, ndi mphira wa styrene-butadiene, ndikusunga mawonekedwe amsana omwe amakhala ambiri.
Ma mphira onse a halogenated ali ndi zinthu zofanana kwambiri.Chlorine, komabe, imawonjezera kuyambiranso kwa malo ochiritsira zomwe zimapangitsa kuchira mwachangu komanso kumamatira bwino kwa ma elastomers osatulutsidwa.
Mapulogalamu
Ma raba onse a butyl ndi halobutyl amapereka kusungitsa bwino kwa inflation.Ndiwosankha bwino pamachubu amkati a njinga, magalimoto, ndi matayala a mafakitale ndi aulimi.M'malo mwake, ma halogenated butyl rubber ndi omwe amagwiritsidwa ntchito kwambiri pazitsulo zamkati zamatayala.Ma rabara a halobutyl amagwiritsidwanso ntchito popanga ma hoses, zisindikizo, nembanemba, zomangira matanki, malamba otumizira, zovala zodzitchinjiriza komanso zinthu za ogula, monga zikhodzodzo za mpira pazinthu zamasewera.Ma halobutyl nthawi zambiri amakhala chisankho chabwino pakafunika kukana mankhwala, nyengo, ndi ozoni.
Gwiritsani ntchito
Amagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana za mphira zolimbana ndi mafuta, ma gaskets osiyanasiyana osamva mafuta, ma gaskets, manja, zonyamula zofewa, payipi yosinthika, kusindikiza ndi utoto wodzigudubuza wa mphira, zida za mphira, etc. zakhala zofunikira zotanuka mugalimoto , ndege, mafuta, kukopera ndi mafakitale ena.
