I. Incamake y'ibicuruzwa: Umushongi ushyuha cyane kandi ushyuha cyane
Diethylene Glycol Monobutyl Ether, ikunze kuvugwa mu magambo ahinnye nka DEGMBE cyangwa BDG, ni igikoresho cy’umwimerere kidafite ibara, gifite impumuro ntoya nk’iya butanol. Nk’igice cy’ingenzi cy’umuryango wa glycol ether, imiterere yacyo ya molekile irimo imigozi ya ether n’amatsinda ya hydroxyl, ibi biyiha imiterere yihariye ya fizikiki ituma iba “ikintu cy’ingenzi gishyuha hagati na hagati, kidahindagurika cyane.”
Ingufu z'ingenzi za DEGMBE ziri mu buryo budasanzwe bwo gushonga no guhuza. Igaragaza ubushobozi bukomeye bwo gushonga ku bintu bitandukanye byo mu kirere n'ibitari byo mu kirere, nka resins, amavuta, amarangi, na selulose. Icy'ingenzi kurushaho, DEGMBE ikora nk'igikoresho cyo guhuza, bigatuma sisitemu zitari zihuye mbere (urugero: amazi n'amavuta, resins y'umwimerere n'amazi) zikora ibisubizo bihamye cyangwa emulsions. Iki kintu cy'ingenzi, hamwe n'umuvuduko wayo uciriritse wo guhumeka n'ubushobozi bwiza bwo kugorora, ni byo bishyiraho urufatiro rw'ikoreshwa rya DEGMBE mu nzego zikurikira:
●Inganda zikora irangi n'amabara: Ikoreshwa nk'ikintu gishongesha kandi gihuza amarangi akozwe mu mazi, amarangi ya latex, amarangi yo gutekesha mu nganda, n'amabara yo gucapa, irushaho kunoza uburyo firime ingana n'iy'urumuri kandi ikarinda firime gucika ku bushyuhe buke.
●Imashini zisukura n'izikuraho amarangi: DEGMBE ni ingenzi mu bikoresho byinshi bisukura, bikuraho amavuta, n'ibikuraho amarangi, ishongesha neza amavuta n'amafilimi ashaje y'irangi.
●Gutunganya imyenda n'uruhu: Bikoreshwa nk'umusemburo w'irangi n'ibindi bikoresho bifasha mu gukora irangi, bikorohereza kwinjira mu buryo bumwe.
●Imiti ikoreshwa mu byuma bisukura hakoreshejwe ikoranabuhanga: Ikora mu bikoresho bisukura hakoreshejwe ikoranabuhanga (photoresist strippers) ndetse no mu bikoresho bimwe na bimwe bikoreshwa mu gusukura hakoreshejwe ikoranabuhanga.
● Izindi nzego: Zikoreshwa mu kwica udukoko, mu byuma bikoreshwa mu gukora ibyuma, mu mavuta ya polyurethane, n'ibindi byinshi.
Bityo, nubwo DEGMBE idakora mu buryo butaziguye ibikoresho nk'ibice binini, ikora nk'"MSG y'inganda" y'ingenzi - igira uruhare rudasimburwa mu kongera imikorere y'ibicuruzwa no guhagarara neza mu nganda nyinshi ziri munsi yayo.
II. Amakuru Mashya: Isoko Rifite Ubukene Buto bw'Ibicuruzwa n'Ibiciro Bihanitse
Mu minsi ishize, bitewe n’impinduka mu mikorere y’inganda ku isi ndetse n’ihindagurika ry’ibikoresho fatizo, isoko rya DEGMBE ryaranzwe n’igabanuka ry’ibiciro ndetse n’ibiciro biri hejuru.
Ubushyuhe bwa Ethylene Oxide mu bikoresho fatizo butanga inkunga ikomeye
Ibikoresho by'ingenzi bya DEGMBE ni ethylene oxyde (EO) na n-butanol. Bitewe n'uko EO ishobora gushya no guturika, ingano yayo mu bucuruzi ni mike, hamwe n'itandukaniro rikomeye ry'ibiciro mu karere ndetse n'ihindagurika rya buri gihe. Vuba aha, isoko ry'imbere mu gihugu rya EO ryakomeje kuzamuka ku giciro, bitewe n'imiterere ya ethylene ndetse n'uburyo bwayo bwo gutanga no gukenera, bigatuma DEGMBE irushaho gutakaza agaciro. Ihindagurika iryo ari ryo ryose ku isoko rya n-butanol naryo rihita rigera ku giciro cya DEGMBE.
Itangwa ry'ibikoresho rirambye
Ku ruhande rumwe, zimwe mu nganda zikomeye zikora ibicuruzwa zagiye zifungwa mu buryo buteganyijwe cyangwa butari buteganyijwe kugira ngo zibungabungwe mu gihe gishize, ibyo bikaba byaragize ingaruka ku itangwa ry’ibikoresho. Ku rundi ruhande, ububiko rusange bw’inganda bwakomeje kuba ku rwego rwo hasi. Ibi byatumye habaho ibura rya DEGMBE ku isoko, aho abacuruzi bakomeza kugaragaza imyumvire yabo.
Ubusabe butandukanye bwo mu gihe cy'ibiza
Kubera ko ari urwego runini rw’ikoreshwa rya DEGMBE, icyifuzo cy’inganda zikora irangi gifitanye isano rya bugufi n’iterambere ry’ubutaka n’ibikorwa remezo. Muri iki gihe, icyifuzo cy’irangi ry’inyubako kiracyari gihamye, mu gihe icyifuzo cy’irangi ry’inganda (urugero: irangi ry’imodoka, iry’amazi, n’iry’ibikoresho) gitanga imbaraga ku isoko rya DEGMBE. Ibyifuzo mu nzego gakondo nko gukora isuku biracyari bihamye. Kwemera kwa abakiriya ba DEGMBE ku giciro gito byabaye ikintu cy’ingenzi mu mikino yo ku isoko.
III. Imiterere y'inganda: Kuvugurura ibidukikije n'iterambere rinoze
Mu gihe urebye imbere, iterambere ry’inganda za DEGMBE rizajyana cyane n’amabwiriza agenga ibidukikije, iterambere ry’ikoranabuhanga, n’impinduka mu isabwa ry’isoko.
Ibiganiro ku ivugurura ry'ibicuruzwa no kubisimbuza bigengwa n'amabwiriza agenga ibidukikije
Hari ibintu bimwe na bimwe bivangavanga glycol ether (cyane cyane E-series, nka ethylene glycol methyl ether na ethylene glycol ethyl ether) bigengwa cyane bitewe n’ibibazo by’uburozi. Nubwo DEGMBE (ishyirwa mu byiciro bya P-series, ni ukuvuga propylene glycol ethers, ariko rimwe na rimwe ikavugwa mu byiciro gakondo) ifite uburozi buke kandi ikoreshwa mu buryo bwinshi, icyerekezo cy’isi yose cya "chemistry green" no kugabanuka kw’ibyuka bya VOC (Volatile Organic Compounds) byashyize igitutu ku nganda zose zivangavanga ibiribwa. Ibi byatumye ubushakashatsi n’iterambere bitangira ubundi buryo butangiza ibidukikije (urugero, bimwe muri propylene glycol ethers) kandi bituma DEGMBE ubwayo itera imbere igana ku buziranenge bwinshi no kugabanuka k’ubuziranenge.
Ivugurura ry'inganda rikomeje gutuma abantu basaba kunoza ibikorwa byabo
Iterambere ryihuse ry’amabara yo mu nganda agezweho (urugero: amarangi y’inganda ashingiye ku mazi, amabara akomeye cyane), irangi rikora neza cyane, n’ibinyabutabire by’ikoranabuhanga byashyizeho amabwiriza akomeye ku isuku y’ibinyabutabire, ubuziranenge, n’ibisigazwa by’ibintu. Ibi bisaba abakora DEGMBE gushimangira igenzura ry’ubuziranenge no gutanga ibicuruzwa bya DEGMBE byihariye cyangwa bifite imiterere ihanitse bihuye n’ibikenewe byihariye mu ikoreshwa ry’ibinyabutabire.
Impinduka mu miterere y'ubushobozi bw'umusaruro mu karere
Ubushobozi bw'umusaruro wa DEGMBE ku isi bwibanda cyane cyane mu Bushinwa, Amerika ya Ruguru, Uburayi bw'Iburengerazuba, n'ahandi muri Aziya. Mu myaka ya vuba aha, ubushobozi bw'umusaruro n'ingaruka by'Ubushinwa byakomeje kwiyongera, bishyigikiwe n'uruhererekane rw'inganda n'isoko rinini riri hasi. Mu gihe kizaza, imiterere y'ubushobozi bw'umusaruro izakomeza kwegera amasoko akomeye y'abaguzi, mu gihe ikiguzi cy'ibidukikije n'umutekano kizaba ibintu by'ingenzi bigira ingaruka ku ipiganwa ry'akarere.
Kunoza Imikorere no Guhuza Uruhererekane rw'Inganda
Kugira ngo bongere ubushobozi bwo guhangana n’ibiciro no kudahungabana kw’ibiciro, inganda zikomeye zikunda kunoza uburyo bwo gukora DEGMBE binyuze mu kunoza ikoranabuhanga, kongera ikoreshwa ry’ibikoresho fatizo n’umusaruro w’ibicuruzwa. Hagati aho, ibigo bifite ubushobozi bwo gukora ethylene oxide cyangwa alcohol mu nganda bifite amahirwe akomeye yo kudahura n’ingaruka mbi mu ipiganwa ku isoko.
Muri make, nk'ikintu cy'ingenzi gitanga umusaruro, isoko rya DEGMBE rifitanye isano ya hafi n'inganda zikora ibintu bitandukanye nko gusiga irangi no gusukura—bigatuma iterambere ryabo rirushaho kuba ryiza. Bahanganye n'ibibazo bibiri by'ibiciro by'ibikoresho fatizo n'amategeko agenga ibidukikije, inganda za DEGMBE zirimo gushaka amahirwe mashya yo kuringaniza no guteza imbere ibicuruzwa binyuze mu kunoza ireme ry'ibicuruzwa, kunoza imiyoboro y'ibicuruzwa, no kumenyera ibikenewe cyane, bakareba ko iki “gikoresho gitanga umusaruro mwinshi” gikomeza kugira uruhare runini mu nganda zigezweho.
