Bromated Butyl Rubber (BIIR)

Ibisobanuro bigufi:

Bromated butyl rubber (BIIR) ni isobutylene isoprene copolymer elastomer irimo bromine ikora.Kuberako bromine ya butyl reberi ifite urunigi nyamukuru rwuzuyemo cyane na butyl reberi, ifite imikorere itandukanye iranga butyl polymer, nkimbaraga nyinshi zumubiri, imikorere myiza yo kunyeganyega, gukora neza, kwihanganira gusaza no kurwanya gusaza kwikirere.Guhimba no gukoresha halogenated butyl rubber imbere yimbere byageze kumapine ya radiyo igezweho mubice byinshi.Gukoresha polimeri nkiyi murwego rwimbere rwimbere rushobora kunoza imikorere yumuvuduko, kunoza guhuza hagati yimbere yimbere nintumbi no kunoza igihe ipine.

Butyl rubber ni polymer yumurongo hamwe na isobutylene nkumubiri nyamukuru hamwe na isoprene nkeya.Ku ruhererekane nyamukuru rwa molekile ya butyl, andi matsinda yose ya methylene, hari amatsinda abiri ya methyl yatunganijwe muburyo buzengurutse urunigi runini, bigatera inzitizi nini cyane, bigatuma imiterere ya molekile ya butyl reberi ihuza kandi urunigi rwa molekile rukaba rworoshye cyane. .Ariko, ituma kandi butyl reberi nziza cyane muburyo bwo guhumeka ikirere, ikaza kumwanya wa mbere muri reberi zose.

Usibye gukomera kwumwuka mwiza, ariko butyl rubber vulcanizates nayo irwanya ubushyuhe bwiza.Rubberi ya butuline ya butul irashobora gukoreshwa mu kirere igihe kirekire kuri 100 ℃ cyangwa ubushyuhe buke.Ubushyuhe bwa serivisi ya butyl rubber yatewe na resin irashobora kugera kuri 150-200 ℃.Ubushyuhe bwa ogisijeni yubushyuhe bwa butyl reberi ni ubwoko bwangirika, kandi gusaza bikunda koroshya.Bitewe no kudahaza kwinshi kwurunigi rwa molekile ya butyl reberi hamwe nubushakashatsi bwimiti ya inert, butyl reberi ifite ubushyuhe bwiza na ogisijeni irwanya gusaza.

Uburyo bwubucuruzi: bromated butyl rubber nigicuruzwa cyacu.Ibicuruzwa byibuze ni toni 20.

Gusaba

1. Gusaba ipine yimodoka hamwe nipine yimodoka:
Rubber ya Butyl ifite imbaraga zo kurwanya ubushyuhe no kurwanya amarira.Imiyoboro y'imbere (harimo na moto n'amagare) ikozwe muri reberi ya butyl irashobora gukomeza kugira imbaraga no kurira nyuma yo kumara igihe kinini ihura n’ibidukikije, bigabanya ibyago byo guturika mugihe cyo kuyikoresha.Imiyoboro ya butyl reberi irashobora gukomeza ubuzima bwipine n’umutekano mugihe cy'ubushyuhe bwinshi cyangwa mubihe byinshi.Amosozi mato arashobora kugabanya ubunini bwumwobo kandi bigatuma gusana umuyoboro wimbere wa butyl byoroshye kandi byoroshye.Kurwanya okiside nziza hamwe na ozone irwanya butyl rubber ituma butyl reberi yimbere ifite imbaraga zo kwangirika kwinshi, kandi kuramba hamwe nubuzima bwa serivisi nibyiza kuruta reberi yimbere.Umuyaga muke cyane wa butyl reberi ituma umuyoboro wimbere wakozwe muriwo ubikwa kumuvuduko ukabije wifaranga mugihe kirekire.Iyi mikorere idasanzwe ituma ipine yinyuma yambara neza kandi itanga ubuzima bwiza bwikamba.Ongera ubuzima bwa serivisi yipine yo hanze, wongere ituze numutekano wo gutwara, kugabanya guhangana, hanyuma ugabanye lisansi kugirango ugere ku ntego yo kuzigama ingufu.

2. Gusaba mu icupa ryubuvuzi:
Guhagarika amacupa yubuvuzi nigicuruzwa cyihariye cya reberi yo gufunga no gupakira bihuza nibiyobyabwenge.Imikorere nubuziranenge bigira ingaruka ku buryo butaziguye ku mikorere, umutekano, umutekano uhamye no korohereza ibiyobyabwenge.Corks yubuvuzi ikunze guhindagurika mugihe cy'ubushyuhe bwinshi hamwe nubushyuhe bukabije cyangwa mumiti itandukanye yica udukoko, kandi rimwe na rimwe bikenera kubikwa igihe kirekire mugihe cy'ubushyuhe buke.Kubwibyo, haribisabwa cyane kumiterere yimiti, imiterere yubukanishi hamwe nibinyabuzima bya reberi.Kubera ko icupa rihagarika guhura n’ibiyobyabwenge, rishobora kwanduza ibiyobyabwenge bitewe no gukwirakwiza ibintu bivanwa mu icupa ry’icupa mu biyobyabwenge, cyangwa bikagabanya ibikorwa by’ibiyobyabwenge bitewe no kwinjiza bimwe mu biyobyabwenge icupa.Rubber ya butyl ntabwo ifite ubushobozi buke gusa, ahubwo ifite kandi imbaraga nziza zo kurwanya okiside, aside na alkali, kurwanya ubushyuhe no kurwanya imiti yangiza.Nyuma yo gukoresha icupa rya butyl reberi, uruganda rukora imiti rushobora koroshya uburyo bwo gupakira, gukoresha capine ya aluminiyumu, gukuraho ibishashara bifunga no kugabanya igiciro, kandi birashobora no koroshya gukoresha inshinge.

3. Ibindi bikorwa:
Usibye imikoreshereze yavuzwe haruguru, butyl rubber ifite imikoreshereze ikurikira: (1) umurongo wibikoresho bya shimi.Bitewe nubwiza buhebuje bwo kurwanya ruswa, butyl reberi yabaye ibikoresho byatoranijwe kugirango ibashe kwangirika.Ijwi ryinshi rya butyl reberi mumashanyarazi atandukanye ni rito cyane, nimwe mumpamvu zingenzi zituma reberi ya butyl ikoreshwa muriki gice.(2) Imyenda ikingira hamwe nibintu birinda.Nubwo ibikoresho byinshi bya pulasitike bifite uburyo bwiza bwo kwigunga no kurinda, ibikoresho bya elastike gusa birashobora kuzirikana guhinduka bikenewe kugirango imyuka yoroheje kandi yorohewe.Kubera ubushobozi buke bwamazi na gaze, butyl reberi ikoreshwa cyane mumyenda ikingira, ponchos, ibipfukisho birinda, masike ya gaze, gants, udukariso hamwe na bote.

Kwitegura

Hariho uburyo bubiri bwibanze bwo gukora bwa reberi isanzwe ya butyl: uburyo bworoshye nuburyo bwo gukemura.Uburyo bwo gusebanya burangwa no gukoresha chloromethane nkururimi rwamazi-alcl3 nkuwatangije.Ku bushyuhe buke bwa - 100 ℃, isobutylene hamwe na isoprene nkeya ihura na cololymerisation.Inzira ya polymerisation isaba gukoresha catalizator.Kugirango tunoze imikorere ya catalizator, birakenewe gukoresha cocatalysis kugirango utangire polymerisation mubihe byinshi.Ikoranabuhanga mu gukora ryihariwe n’amasosiyete yo muri Amerika y’amahanga n’amasosiyete yo mu Budage.Uburyo bwo gukora butyl reberi hakoreshejwe uburyo bwa slurry bukubiyemo intambwe enye: polymerisiyonike, gutunganya ibicuruzwa, gutunganya no gutunganya isafuriya.Uburyo bwo gukemura bwateguwe nu Burusiya taoriati synthique ya rubber na sosiyete yo mubutaliyani.Ikiranga tekiniki nuko uruganda rwa alkyl aluminium chloride namazi bikoreshwa nkintangiriro yo gukoporora isobutene hamwe na isoprene nkeya muri hydrocarbon solvent (nka isopentane) ku bushyuhe bwa - 90 kugeza 70 ℃.Inzira nyamukuru yumusaruro wa butyl ukoresheje uburyo bwo gukemura harimo gutegura, gukonjesha, polymerisiyasi ya sisitemu yo gutangiza nibindi bivanze, kuvanga igisubizo cya reberi, gutesha agaciro no kwiyambura, kugarura no gutunganya monomer ikemurwa, nyuma yo kuvura reberi, nibindi. inzira nyamukuru zifasha zirimo gukonjesha, gusukura reaktor, gutegura inyongera, nibindi
