Dimethyl thio-toluene Diamine DMTDA yog dab tsi?

DMTDA yog ib hom tshiab ntawm polyurethane elastomer curing thiab crosslinking tus neeg sawv cev, nyob rau hauv uas muaj feem ntau yog ob isomers, uas yog cov sib tov ntawm 2,4 - thiab 2,6 - dimethylthiotoluene diamine (tus piv yog hais txog 77 ~ 80/17 ~ 20). Piv nrog rau MOCA uas nquag siv, DMTDA yog cov kua uas tsis muaj viscosity ntawm qhov kub thiab txias, uas tuaj yeem siv rau kev tsim kho ntawm qhov kub thiab txias, thiab muaj cov tshuaj sib npaug.

Daim ntawv thov

1. Nws yog ib hom tshiab ntawm cov kua tshuaj tua kab mob rau polyurethane elastomer. Nws yog dav siv hauv polyurethane casting, txheej, RIM, SPUA, polyurethane log thiab nplaum rau cov saw txuas ntxiv lossis kev sib txuas, thiab tseem yog tus neeg sawv cev kho rau epoxy resin.

2. Raws li hardener, thaum ntxiv rau TDI thiab MTDI ob-kua polyurethane elastomers, nws yuav tsum tau ntxiv ntawm tus nqi ntawm 10%. Hauv kev tsim kho thiab kev lag luam hauv kev lag luam, nws feem ntau yog siv los ua ib qho ntxiv rau cov txheej txheem hluav taws xob (txheej txheej sab saum toj thiab sab phab ntsa), kev tiv thaiv corrosion ntawm cov ntaub ntawv hlau (txheej rau ntawm phab ntsa ntawm cov yeeb nkab hlau), thiab lwm yam. Cov khoom siv polyurethane uas tuaj yeem hnov mob nrog lwm yam tshuaj yam tsis muaj kev kho mob zoo dua rau cov khoom ntawm MOCA (Mocha) hardener.
3. Siv rau polyurethane luam ntawv roj hmab scraper, roj yeeb nkab tu scraper, thiab lwm yam., los txhim kho cov roj tsis kam ntawm polyurethane, thiab lub ntim expansion npaum li cas.
4. Tsis tas li ntawd, nws yog dav siv nyob rau hauv textile, ntawv thiab luam ntawv industries. Nws tuaj yeem hais tias nws muaj kev lag luam dav los ntawm kev lag luam aviation thiab aerospace mus rau kev lag luam dav dav.
