Nitrile ya carboxyl yarangiye ni iki?

Carboxyl-yarangiye ya butadiene nitrile (CTBN) polymer ni elastomer ifite imashini nziza, irwanya imiti na chimique. Iyi mitungo idasanzwe ituma CTBN ikoreshwa cyane mubikorwa bitandukanye. Muri iyi ngingo, tuzasuzuma nitrile ya carboxyl yarangiye na nitrile ikoreshwa nibisabwa mubice bitandukanye.

 Carboxyl-yarangiye butadiene nitrile ni kopolymer ya butadiene na acrylonitrile ikora carboxylation mugihe cyo gukora. Iyi nzira itangiza amatsinda yimikorere ya carboxyl mumurongo wa polymer, ikazamura imiterere yayo. Copolymer yavuyemo ifite uburemere buke bwa molekuline, indangagaciro ya polydispersity nkeya, hamwe no gukemuka neza mumashanyarazi atandukanye.

Carboxyl yarangiye butadiene nitrile polymers izwiho kurwanya cyane ubushyuhe, amavuta, ibicanwa, amazi ya hydraulic nindi miti myinshi. Ubushobozi bwayo bwo guhangana nubushyuhe bukabije kuva kuri -40 ° C kugeza kuri 150 ° C, hamwe na ozone nziza cyane hamwe n’imihindagurikire y’ikirere, bituma iba ibikoresho byiza byo gusaba.

Bumwe mu buryo bukoreshwa bwa carboxyl-yarangiye butadiene nitrile iri mu nganda zo mu kirere. Bikunze gukoreshwa nkibikoresho bikaze bya epoxy resin ikoreshwa mugukora ibikoresho byubaka indege. Inyongera yaCTBN  itezimbere ingaruka zo kurwanya, gukomera kuvunika hamwe nigihe kirekire muri ibyo bintu. Ubushyuhe bwacyo butuma bugumana imiterere yubukorikori ndetse no ku butumburuke bwo hejuru no mu gihe cy’ubushyuhe bwihuse.

Ubundi buryo bugaragara bwa carboxyl-yarangiye butadiene nitrile iri mubikorwa byimodoka. CTBN isanzwe ikoreshwa nkibintu byingenzi mubitwikiriye, ibifunga hamwe na kashe kubice byimodoka. Amavuta meza cyane, lisansi na chimique irwanya, ihujwe nubworoherane nigihe kirekire, bituma iba ibikoresho byiza kuri gasketi, O-impeta, kashe na diaphragms. Ifasha gukora neza no kuramba kwibigize muri moteri, imiyoboro hamwe na sisitemu ya hydraulic.

Inganda zamashanyarazi nazo zungukira kumiterere yihariye ya carboxyl yarangiye nitrile ya butadiene. Iyi elastomer ikoreshwa cyane mugukora insinga zogukoresha ibikoresho. Polimeri ya CTBN itanga imbaraga zo guhangana nubushuhe, amavuta nubumara, hamwe nimbaraga nyinshi za dielectric hamwe nubushyuhe bwumuriro. Iyi mitungo ituma iba ibikoresho byiza byo kurinda umutekano no kwizerwa bya sisitemu y'amashanyarazi.

Usibye inganda zavuzwe haruguru,carboxyl-yarangiye butadiene nitrile ikoreshwa kandi mugukora amarangi, ibifunga hamwe na kashe, aho guhuza kwayo hamwe nudukoko dutandukanye twangiza cyane. Irakoreshwa kandi mugutegura ibikoresho bya reberi ikora cyane, itanga imbaraga zo kurwanya ingaruka no gukomera.

Muri make, nitrole ya carboxybutadiene ni elastomer ikora cyane hamwe nubukanishi bwiza, ubushyuhe nubumara. Ubwinshi bwibikorwa byayo mu kirere, ibinyabiziga, amashanyarazi n’inganda byagaragaye ko byizewe kandi bikora neza. Mugihe ikoranabuhanga ritera imbere ninganda zisaba ibikoresho byo hejuru, CTBN ikomeje gutera imbere no gutanga umusanzu mubikorwa bitandukanye, bituma iba ibikoresho byingirakamaro mubikorwa byinshi.
