Cov khoom
Chlorobutyl (CIIR) thiab bromobutyl (BIIR) elastomers yog copolymer ntawm halogenated isobutylene (Cl, Br) thiab me me ntawm isoprene uas muab qhov chaw tsis txaus rau vulcanization.Kev taw qhia ntawm bromine los yog chlorine txhim kho kev tiv thaiv ozone, huab cua, tshuaj, thiab cua sov.Qhov no, txawm li cas los xij, los ntawm kev siv hluav taws xob rwb thaiv tsev thiab dej tsis kam.
Ob leeg bromobutyl (BIIR) thiab chlorobutyl (CIIR) feem ntau muaj cov pob txha saturated ntawm isobutylene.Ob leeg elastomers muaj ntau tus cwj pwm ntawm cov roj hmab butyl zoo tib yam nrog rau cov pa roj tsawg thiab cov dej noo permeability, zoo vibration damping, tsis tshua muaj iav hloov kub, zoo heev tiv thaiv kev laus thiab huab cua, thiab dav vulcanization versatility.
Kev taw qhia ntawm cov tshuaj chlorine los yog bromine nce adhesion rau roj hmab, thiab hlau, txhim kho compatibility nrog diene rubbers nyob rau hauv blends, thiab muab ntau dua curing tus nqi, piv txwv li ib tug txo tus nqi ntawm curative yuav tsum tau.Tsis tas li ntawd, halogenated butyl tuaj yeem co-vulcanized nrog lub hom phiaj dav dav uas tsis muaj qhov tsis txaus ntseeg elastomers, xws li cov roj hmab ntuj, polybutadiene, thiab styrene-butadiene roj hmab, thaum tuav cov pob txha feem ntau saturated.
Ob leeg halogenated rubbers muaj cov khoom zoo sib xws.Chlorine, txawm li cas los xij, ua rau muaj kev cuam tshuam ntawm cov chaw kho mob uas ua rau muaj kev kho sai dua thiab txhim kho adhesion rau unsaturated elastomers.
Daim ntawv thov
Ob leeg butyl thiab halobutyl roj hmab muab kev ruaj ntseg zoo heev.Lawv yog qhov kev xaiv zoo tshaj plaws rau cov raj sab hauv ntawm cov tsheb kauj vab, tsheb thauj khoom, thiab cov log tsheb ua liaj ua teb thiab kev lag luam.Qhov tseeb, halogenated butyl roj hmab yog cov siv dav siv butyl roj hmab rau cov log tsheb sab hauv.Halobutyl rubbers kuj tseem siv rau hoses, seals, membranes, tank linings, conveyor siv, tiv thaiv khaub ncaws thiab rau cov neeg siv khoom, xws li pob zais zis rau cov khoom ua si.Halobutyls feem ntau yog ib qho kev xaiv zoo thaum muaj kev tiv thaiv zoo rau cov tshuaj, huab cua, thiab ozone.
Siv
Nws yog dav siv nyob rau hauv kev tsim khoom ntawm ntau yam roj resistant roj hmab cov khoom, ntau yam roj resistant gaskets, gaskets, lub tes tsho, mos ntim, saj zawg zog hose, luam ntawv thiab dyeing roj hmab rollers, cable roj hmab cov ntaub ntawv, thiab lwm yam. nws tau dhau los ua ib qho tseem ceeb elastic khoom nyob rau hauv lub tsheb. , aviation, roj av, luam ntawv thiab lwm yam kev lag luam.
