1,4-ButanediolCAS110-63-4: Umukinnyi ukoresha uburyo bwinshi mu nganda z'ibinyabutabire, azana urujya n'uruza rw'ibikoresho bitandukanye

Vuba aha, 1,4-butanediol (BDO) yabaye ingingo ikunzwe cyane mu bijyanye n'imiti. Nk'ikintu cy'ingenzi mu binyabutabire by'umwimerere, irimo gushyira imbaraga nshya mu nganda nyinshi zifite uburyo bwinshi bwo kuyikoresha, bigatuma habaho iterambere rikomeye ry'uruhererekane runini rw'inganda.

Ku mikorere y'ibicuruzwa bya polyester, 1,4-butanediol igaragaza agaciro kadasimburwa. Uburyo bwo gukora polybutylene terephthalate (PBT) bushingiye cyane kuri yo. PBT, nk'iplastike ikora neza ya polyester ikora neza cyane, ifite imiterere idasanzwe ya mekanike, irwanya ingese cyane, kandi irinda amashanyarazi neza kandi ihamye. Muri iki gihe, inganda z'ibikoresho by'amashanyarazi n'amashanyarazi zirimo kwaguka vuba, hamwe n'ibikoresho bitandukanye byo mu rugo bigezweho n'ibikoresho by'ikoranabuhanga bigezweho bihora bizamuka. Ibikoresho by'amashanyarazi bikozwe mu bikoresho bya PBT ntibituma ibikoresho biguma neza gusa, ahubwo binatuma ibicuruzwa bigira isura nziza kandi irambye, bigatuma isoko rirushaho gukenera cyane. Inganda zikora imodoka nazo zigaragaza ko zikunda cyane PBT. Ibice nk'imigozi y'inzugi z'imodoka n'udupira twakozwe muri PBT bishobora kwihanganira kwangirika kw'imiterere y'umuhanda mu buryo bugoye mu gihe bikongera imiterere y'imodoka muri rusange.

Mu ikorwa rya polyurethane ya thermoplastic (TPU), 1,4-butanediol nayo ni "igice cy'ingenzi". TPU ihuza uburyo bworoshye bwo gutunganya umupira n'uburyo bworoshye bwo gutunganya pulasitiki, kandi ibicuruzwa byayo birangirika, ntibikoresha amavuta, kandi ntibikonje. Kuva ku nkweto za siporo za buri munsi, zitanga ubufasha bwiza kandi burambye ku bakunzi ba siporo, kugeza ku miyoboro, insinga n'ibikoresho by'insinga mu nganda, birinda umutekano wo kohereza ingufu no gutwara ibikoresho, hanyuma kugeza ku mikandara y'inganda yihuta cyane, igenzura ko umurongo w'umusaruro ukora neza, TPU iri ahantu hose, kandi ni wo musingi w'imikorere washyizweho na 1,4-butanediol ituma bishoboka.

Inganda zikora irangi, irangi, n’izikora irangi nazo zahinduye ibintu bishya vuba aha bitewe na 1,4-butanediol. γ-butyrolactone ikorwamo ifite ubushyuhe bwinshi kandi irashongesha neza, ishobora gushonga byoroshye ibintu bitandukanye by’umwimerere na polimeri, bigatuma amabara y’irangi arushaho kuba amwe, irangi rikomera, kandi imiterere yo gucapa no gusiga irangi irushaho kuba nziza kandi igaragara neza, bigira uruhare mu kuvugurura inganda gakondo z’imiti. Byongeye kandi, nk'ibikoresho byo gutangira gukora ibirungo n'ibindi bikoresho bikoreshwa mu buvuzi, γ-butyrolactone irimo gufungura bucece amarembo mashya y’ubushakashatsi n’iterambere ry’imiti myiza, kandi byitezwe ko izabyara ibindi bicuruzwa bishya bizatangizwa ku isoko.

Mu gihe cy’ubwiyongere bw’inganda zikora bateri ya lithium, N-methylpyrrolidone (NMP), ikomoka kuri 1,4-butanediol, yakuruye abantu benshi. Nk’umusemburo wa polar aprotic, NMP yatsinze ikibazo cy’uburyo ibikoresho bya bateri ya lithium bidashonga neza, byoroshya ivanga ry’ibikoresho bifunga n’ibikoresho bikora. Ni yo ntwari idashimwa inyuma yo kunoza imikorere n’ubwiza bwa bateri ya lithium, ishyigikira cyane uburyo bushya bwo gukora inganda nk’imodoka nshya zikoresha ingufu n’ibikoresho byo kubika ingufu.

Ku mpande z'imideli n'imyenda, tetrahydrofuran (THF) ikorwa hifashishijwe 1,4-butanediol irushaho guhindurwamo polytetrahydrofuran (PTMEG), iba ibikoresho fatizo bya spandex fibres na polyurethane elastomers. Ibi bituma imyenda ya siporo n'imyambarire yo mu rwego rwo hejuru bihuzwa neza n'imiterere y'umubiri w'umuntu, bihuza ihumure n'imyambarire, kandi biha imyenda ubushobozi bworoshye kandi ikora neza.

Mu rwego rw'ubushakashatsi n'iterambere ry'imiti, 1,4-butanediol ikora bucece nk' "intwari idakunzwe cyane". Nk'umuhuza w'ingenzi mu by'imiti, igira uruhare mu ntambwe zikomeye zo gukora imiti imwe n'imwe ya steroide na antibiyotike. Ni nk'inkingi zoroshye zo kubaka inyubako ya molekile, igafasha abashakashatsi gushushanya inyubako nziza z'imiti no gutanga intwaro zo gutsinda indwara zikomeye.

Bitewe n’iterambere rihoraho ry’ikoranabuhanga no gushakisha byimbitse ku isoko, byitezwe ko inganda za 1,4-butanediol zizakomeza kwaguka, aho inganda zo mu rwego rwo hejuru n’izo mu rwego rwo hasi zifatanya mu guhanga udushya no kuzamuka mu nzego zigezweho, bikandika igice gishya cyiza mu nganda z’ubutabire.
