Bitewe n’ubwiyongere bukomeje bw’ubwiyongere bw’ibikenewe mu nganda nshya z’ibikoresho nka polyurethane na epoxy resin,dimethyl thio-toluene diamine(DMTDA, nimero ya CAS: 106264-79-3) buhoro buhoro yabaye imbaraga nyamukuru mu kuvugurura inganda bitewe n'imiterere yazo yihariye n'uburyo zikoreshwa mu buryo bugari. Nk'ubwoko bushya bw'ibikoresho bivura aromatic diamine n'umuyoboro w'insinga, DMTDA igenda isimbuza ibikoresho bisanzwe bivura aromatic. Dimethyl thio-toluene diamine yakoreshejwe ku rugero runini mu nzego zitandukanye nko mu modoka, mu bwubatsi, mu muyoboro w'insinga ukonje, no mu kurwanya ingese, bigateza imbere inganda kugira ngo zihinduke zigana ku iterambere riciriritse rikoresha karubone nke, rikora neza cyane kandi rigezweho.

Ibiranga dimethyl thio-toluene diamine (DMTDA)

Ibyiza by'ingenzi byaDimethyl thio-toluene diamine (DMTDA)Bikomoka ku miterere yabyo ifatika yo kuba mu rugero rw'amazi mu bushyuhe bw'icyumba ndetse n'imikorere yabyo myiza ya shimi. Ugereranyije n'umuti usanzwe wo gukangura ibintu ukomeye MOCA, iki gicuruzwa gishobora kuvomwa mu buryo butaziguye no gukoreshwa nta gushyushya. Ibi ntibigabanya gusa ikoreshwa ry'ingufu n'uburemere bw'imikorere mu gikorwa cyo kugitunganya, ahubwo bishobora no gukoreshwa mu bihe by'ubushyuhe buke, bigakemura neza ibibazo by'inganda nko gukangura ibikoresho bikangura ibintu mu gihe cy'itumba no kubaka ibintu mu buryo butari bwiza.

Amakuru agaragaza ko ubushobozi bwa DMTDA bungana n'inshuro 3.7 z'ubwa MOCA. Ishobora gukora vuba imiterere ya urea ikomeye hamwe na isocyanates, yongera imbaraga zo gukurura no gucika kw'ibicuruzwa bya elastomer ku kigero cya 20%-30%. Ku bushyuhe buri munsi ya dogere selisiyusi 40, iracyakomeza kuba nziza kandi imikorere yayo ya hydrolysis irushaho kuba myiza ku kigero cya 30% ugereranije na MOCA, bigatuma ikwiriye ahantu hakomeye nko mu bushyuhe n'ubushyuhe buke.

Ikoreshwa rya dimethyl thio-toluene diamine (DMTDA)

Mu rwego rwa elastomer za polyurethane, DMTDA yabaye igikoresho cy'ingenzi mu gukora ibicuruzwa byo mu rwego rwo hejuru. Ikoreshwa cyane mu bikorwa nko gutwika elastomer za polyurethane, gukora imashini zikoresha inshinge (RIM), no gutera polyurea (SPUA), kandi ishobora gukoreshwa mu gukora ibicuruzwa nka roller za rubber zigenda cyane, imashini zikoresha imashini zikora, imashini zikoresha imashini zikoresha peteroli, n'ibikoresho bikoresha imashini zi ...

Ubwubatsi n'ubuhanga mu kurwanya ingese ni ikindi kintu cy'ingenzi gikoreshwa muriDMTDANk'umuti uvura epoxy resin, dimethyl thio-toluene diamine ishobora gukoreshwa mu gutegura irangi rirwanya ingese n'irangi ririnda inkongi, rikoreshwa cyane mu kurwanya ingese ku nkuta z'imbere z'imiyoboro y'icyuma, mu gutunganya ibisenge by'inyubako no ku nkuta zo ku ruhande, nibindi. Irangi rivuguruye rifite uburyo bwiza bwo gufata neza, rirwanya ingese kandi rigakomera mu miterere, ibyo bikaba bishobora kongera igihe cy'ibikorwa remezo. Mu bihe birimo ingese nyinshi nk'ibikoresho by'ubuhanga mu by'amazi n'ubucukuzi bw'amabuye y'agaciro, irangi rishingiye kuri DMTDA rishobora kurwanya isuri ituruka mu mazi yo mu nyanja, aside na alkaline, rigabanya cyane ikiguzi cyo kubungabunga ibikoresho, kandi rigafasha mu kuvugurura ikoranabuhanga mu rwego rwo kurwanya ingese ku rwego rwo hejuru.

Amahirwe yo guteza imbere dimethyl thio-toluene diamine (CAS 106264 79 3)

Gukurikiza ibidukikije n'ubushobozi bw'isoko byarushijeho kwihutisha inzira yo gusimbuza dimethyl thio-toluene diamine. Kubera ko uturere nka EU dushyira mu bikorwa amategeko agenga ikoreshwa ry'ibintu bihumanya nka MOCA, DMTDA amine idafite uburozi bwinshi kandi idahumanya ibidukikije yabaye amahitamo meza mu nganda. Ntiyubahiriza gusa amabwiriza mpuzamahanga yo kurengera ibidukikije, ahubwo inagabanya ivumbi mu gihe cyo gukora no kongera umutekano w'ibikorwa byo mu iduka. Ukurikije uko isoko rihagaze, ingano y'isoko mpuzamahanga rya DMTDA n'ibindi bisa naryo yageze kuri miliyari 2.873 z'amayuani mu 2024. Biteganijwe ko izakura ku gipimo cy'ubwiyongere bwa 17.06% kuva mu 2025 kugeza 2030. Muri byo, ubutaka bwa polyurethane elastomer ni bwo bukoreshwa cyane, kandi ukwiyongera kw'ibikenewe bivuye mu nganda zigezweho byabaye imbaraga nyamukuru zo kwagura isoko.

Impuguke mu nganda zavuze ko ikoreshwa ryagutse ryaDMTDA ethacure 300Ntibiteza imbere gusa ivugurura ry’ibicuruzwa mu nganda zikora ibikoresho bivura indwara, ahubwo binafasha inganda zo hasi kugera ku kugabanya ikiguzi, kunoza imikorere, no kuvugurura imikorere ku rwego rwo hejuru. Mu gihe kizaza, hamwe n’iterambere rihoraho mu ikoranabuhanga rishya ry’ibikoresho, ikoreshwa rya DMTDA amine mu by’indege, ibikoresho by’ubuvuzi, n’amakori akomeye n’ibindi bicuruzwa bizarushaho kwaguka. Muri icyo gihe, isuku yo hejuru (≥99%) n’ikigereranyo cyihariye cy’ibicuruzwa bya DMTDA bizaba intandaro y’ipiganwa ku isoko kandi biganisha inganda ku cyerekezo cyiza kandi cy’imikorere myiza. Inganda za Unilong, binyuze mu guhanga udushya mu ikoranabuhanga no kwagura ubushobozi, zigenda zirushaho kongera ijwi ryazo ku isoko rya DMTDA ku isi no gutanga inkunga y’ingenzi ku bwigenge no kugenzura uruhererekane rw’inganda.
