Dimethyl thio-toluene Diamine DMTDA ni iki?

Dimethyl thio-toluene diamine (DMTDA), ifite inomero ya CAS 106264-79-3, ni ikintu cy'ingenzi mu binyabuzima. Atome za sulfur ziri muri molekile ya amine ya DMTDA zishobora kongera ubushobozi bwo guhuza ibyuma, kandi icyarimwe zigaha umusaruro wavuwe ubushobozi bwiza bwo kurwanya hidrolisisi no kurwanya ingese mu buryo bwa shimi.

DMTDA ni ubwoko bushya bwa polyurethane elastomer curing and crosslinking agent, aho harimo ahanini isomers ebyiri, ari zo uruvange rwa 2,4 - na 2,6 - dimethylthiotoluene diamine (igipimo ni hafi 77 ~ 80/17 ~ 20). Ugereranyije na MOCA isanzwe ikoreshwa, DMTDA ni amazi afite viscosity nkeya ku bushyuhe busanzwe, ashobora gukoreshwa mu mirimo yo kubaka ku bushyuhe buke, kandi afite ingano ntoya y’ibinyabutabire.

Porogaramu

1. Dimethyl thio-toluene diamineni ubwoko bushya bw'umuti uvura amazi ukoreshwa muri polyurethane elastomer. Dmtda amine ikoreshwa cyane mu gusuka polyurethane, gusiga irangi, RIM, SPUA, ipine ya polyurethane na kole yo kwagura umunyururu cyangwa guhuza, kandi ni umuti uvura epoxy resin.

2. Dmtda ethacure 300 ni umuti uvura epoxy resin kandi ishobora gukoreshwa mu kunoza imikorere ya epoxy resin.

3. Nk'imashini ikora cyane, iyo yongewe kuri TDI na MTDI elastomer ebyiri z'amazi, igomba kongerwamo ku kigero cya 10%. Mu nganda z'ubwubatsi n'iza sivili, dmtda amine ikunze gukoreshwa nk'inyongera mu gusiga irangi ritangiza umuriro (hejuru no ku rukuta rwo ku ruhande), kurinda ingese ku bikoresho by'icyuma (gusiga ku rukuta rw'imbere rw'umuyoboro w'icyuma), n'ibindi bintu. Imashini ikora cyane ya polyurethane ishobora gukorana n'ibindi bintu idakoresheje uburyo ubwo aribwo bwose bwo kuyitunganya iruta ikoreshwa muri MOCA (Mocha) hardener.

4. Ikoreshwa mu gucapa rubber ya polyurethane, gusukura imiyoboro y'amavuta, nibindi, kugira ngo yongere ubushobozi bwo kurwanya amavuta ya polyurethane, kandi ingano yayo nayo ni nto.

5. Byongeye kandi, dmtda amineikoreshwa cyane mu nganda z'imyenda, impapuro n'icapiro. Dimethyl thio-toluene diamine ishobora kuvugwa ko ifite isoko rinini kuva ku nganda z'indege n'iz'indege kugeza ku nganda rusange za leta.

Ibyiza byacu

1. Ibikubiye muri DMTDA yacu birenga cyane amahame ngenderwaho y’inganda, aho buri cyiciro gihora kigera kuri 96%.

2. Kubera ko ifite agaciro ka amine kari hejuru y’ibipimo by’inganda, buri gice kigera kuri 530mgKOH/g, bigatanga umusaruro udasanzwe wo kuvura.

3. Dufite ubushobozi bwo gukora buhagije kandi dufite ibiribwa bishya, twizeza ko ibyo twaguze byuzuzwa vuba, kandi ko ibyo twaguze bishobora kugerwaho mu minsi 5 y'akazi.

4. Uretse gupakira ingoma zacu zisanzwe zipima ibiro 200, dutanga uburyo bwo gupakira bujyanye n'ibyo ukeneye ndetse na serivisi zo gucapa ibirango.
