Nitrile ya butadiene ivanyweho na karubokisili ikoreshwa iki?

Polymer ya butadiene nitrile (CTBN) ya karubokisili ni elastomer ifite ubushobozi bwo kurwanya ubushyuhe, ubushyuhe n'imiti. Iyi miterere idasanzwe ituma CTBN iba ibikoresho bikoreshwa cyane mu nganda zitandukanye. Muri iyi nkuru, turasuzuma icyo bita butadiene nitrile ya butadiene nitrile ari cyo n'ikoreshwa ryayo mu nzego zitandukanye.

 Nitrile ya butadiene ivanyweho na karubokisilini copolymer ya butadiene na acrylonitrile inyura mu nzira ya karubokisilasiyo mu gihe cyo kuyikora. Iyi nzira yinjiza amatsinda y'imikorere ya karubokisilasiyo mu muyoboro wa polymer, yongera imiterere yayo yo gushisha. Copolymer ivamo ifite uburemere bwinshi bwa molekile, ubwinshi buke bwa polydispersity, kandi irashongesha neza mu bintu bitandukanye by'umwimerere.

Polima za butadiene nitrile zikozwe muri karubokisili zizwiho kurwanya ubushyuhe, amavuta, ibicanwa, amazi ya hydraulic n'ibindi bintu byinshi binyabutabire. Ubushobozi bwazo bwo kwihanganira ubushyuhe bukabije kuva kuri -40°C kugeza kuri 150°C, hamwe no kurwanya ozone no guhangana n'ikirere, bituma ziba ibikoresho byiza cyane byo gukoreshwa mu buryo busaba imbaraga nyinshi.

Imwe mu mikoreshereze ikomeye ya butadiene nitrile ivanwaho na karubokisili ni mu nganda z’indege. Ikunze gukoreshwa nk'ikintu gikomeza ibyuma bya epoxy resine bikoreshwa mu gukora inyubako z’indege zivanze. CTBN Ituma ibi binyabutabire bidashobora kwangirika, gukomera no kuramba muri rusange. Ubushyuhe bwayo butuma igumana imiterere yayo ya mekanike ndetse no mu butumburuke buri hejuru ndetse no mu gihe cy'impinduka zihuse z'ubushyuhe.

Indi mikoreshereze ikomeye ya butadiene nitrile ivanwaho na carboxyl iri mu nganda z'imodoka. CTBN ikunze gukoreshwa nk'ikintu cy'ingenzi mu gusiga, kole n'ibifunga ibice by'imodoka. Irwanya amavuta, lisansi n'imiti neza, hamwe no koroha no kuramba kwayo, bituma iba ibikoresho byiza bya gasket, impeta za O, ibifunga na diaphragm. Ifasha mu kwemeza ko ibice muri moteri, transmissions na hydraulic bigenda neza kandi biramba.

Inganda z'amashanyarazi kandi zungukira ku miterere yihariye ya butadiene nitriles zikozwe muri karubokisili. Iyi elastomer ikoreshwa cyane mu gukora ibikoresho byo gukingira insinga no gupfuka insinga. Polima za CTBN zirwanya cyane ubushuhe, amavuta n'imiti, ndetse zikagira imbaraga nyinshi za dielectric n'ubushyuhe burambye. Iyi miterere ituma iba ibikoresho byiza cyane mu kwemeza umutekano n'ubwirinzi bw'imikorere y'amashanyarazi.

Uretse inganda zavuzwe haruguru, butadiene nitrile ivanyweho na karbokisiliIkoreshwa kandi mu gukora amarangi, kole n'ibifunga, aho ihuye n'ibintu bitandukanye bya organic solvents ari ingirakamaro cyane. Ikoreshwa kandi mu gukora ibintu bya rubber bifite imikorere myiza, bitanga ubushobozi bwo kurwanya ingaruka no guhindagurika.

Muri make, carboxybutadiene nitrile ni elastomer ifite imikorere myinshi kandi irwanya ubushyuhe, amashanyarazi n'ibindi binyabutabire. Uburyo ikoreshwa mu ngendo zo mu kirere, imodoka, amashanyarazi n'izindi zagaragaje ko yizewe kandi ikora neza. Uko ikoranabuhanga ritera imbere kandi inganda zigasaba ibikoresho bigezweho, CTBN ikomeje gutera imbere no gutanga umusanzu mu nganda zitandukanye, bituma iba ibikoresho by'agaciro ku bikorwa byinshi.
