Chlorobutyl (CIIR) / bromobutyl (BIIR)

Awọn ohun-ini
Chlorobutyl (CIIR) ati bromobutyl (BIIR) elastomers jẹ copolymers ti isobutylene halogenated (Cl, Br) ati awọn iwọn kekere ti isoprene eyiti o pese awọn aaye ti ko ni itara fun vulcanization.Ifilọlẹ bromine tabi chlorine ṣe atunṣe resistance si ozone, oju ojo, awọn kemikali, ati ooru.Eyi, sibẹsibẹ, wa ni laibikita fun idabobo itanna ati resistance ọrinrin.

Mejeeji bromobutyl (BIIR) ati chlorobutyl (CIIR) ni akọkọ ẹhin ti o kun fun isobutylene.Mejeeji elastomers ni ọpọlọpọ awọn abuda ti roba butyl lasan pẹlu gaasi kekere ati agbara ọrinrin, riru gbigbọn ti o dara, iwọn otutu iyipada gilasi kekere, resistance to dara julọ si ti ogbo ati oju ojo, ati ilodisi vulcanization jakejado.

Awọn ifihan ti chlorine tabi bromine mu ki ifaramọ si awọn rubbers, ati awọn irin, mu ibamu pẹlu diene rubbers ni idapọmọra, ati ki o pese Elo ti o ga curing awọn ošuwọn, ie a kekere iye ti curative wa ni ti beere.Pẹlupẹlu, butyl halogenated le jẹ idapọ-vulcanized pẹlu idi gbogbogbo ti awọn elastomers giga-unsaturation, gẹgẹbi roba adayeba, polybutadiene, ati roba styrene-butadiene, lakoko ti o n ṣetọju igbekalẹ ẹhin ti o kun pupọ julọ.

Awọn rubbers halogenated mejeeji ni awọn ohun-ini ti o jọra pupọ.Chlorine, sibẹsibẹ, mu ifaseyin ti awọn aaye imularada ti o mu ki iwosan yiyara ati imudara imudara si awọn elastomers ti ko ni irẹwẹsi.

Awọn ohun elo
Mejeeji butyl ati halobutyl rubbers pese idaduro titẹ afikun ti o dara julọ.Wọn jẹ yiyan pipe fun awọn ọpọn inu ti awọn kẹkẹ keke, awọn oko nla, ati awọn taya ile-iṣẹ ati ti ogbin.Ni otitọ, awọn rubbers butyl halogenated jẹ awọn rọba butyl ti a lo julọ fun awọn laini inu inu taya taya.Awọn rọba Halobutyl tun jẹ lilo fun awọn okun, awọn edidi, awọn membran, awọn ideri ojò, awọn beliti gbigbe, awọn aṣọ aabo ati fun awọn ọja olumulo, gẹgẹbi awọn apo-apa bọọlu fun awọn ẹru ere idaraya.Halobutyls jẹ yiyan ti o dara ni gbogbogbo nigbati o nilo resistance to dara si awọn kemikali, oju ojo, ati ozone.
