He aha ka Dimethyl thio-toluene Diamine DMTDA?

ʻO DMTDA kahi ʻano hou o ka polyurethane elastomer curing a me ka crosslinking agent, i loko o ka nui o ʻelua isomers, ʻo ia hoʻi ka hui ʻana o 2,4 - a me 2,6 - dimethylthiotoluene diamine (ʻo ka ratio e pili ana i 77 ~ 80/17 ~ 20). Ke hoʻohālikelike ʻia me ka MOCA maʻamau, ʻo DMTDA kahi wai me ka viscosity haʻahaʻa i ka mahana maʻamau, hiki ke hoʻohana ʻia no ka hana kūkulu ʻana i ka haʻahaʻa haʻahaʻa, a he haʻahaʻa kemika like.

Palapala noi

1. He ʻano hou ia o ka wai hoʻōla wai no ka polyurethane elastomer. Hoʻohana nui ʻia ia i ka hoʻolei ʻana i ka polyurethane, ka uhi ʻana, RIM, SPUA, polyurethane tire a me ka hoʻopili ʻana no ka hoʻonui ʻana i ke kaulahao a i ʻole ka hoʻopili ʻana, a he mea hoʻōla no ka resin epoxy.

2. E like me ka paʻakikī, ke hoʻohui ʻia i ka TDI a me MTDI ʻelua-wai polyurethane elastomers, pono e hoʻohui ʻia ma ka helu o 10%. I ke kūkulu ʻana a me ka ʻoihana kīwila, hoʻohana pinepine ʻia ia i mea hoʻohui no ka uhi ʻana i ke ahi (layer top and side wall), corrosion pale o nā mea metala (ka uhi ʻana i ka paia o loko o ka paipu hao), a me nā mea ʻē aʻe. ʻO ka huahana polyurethane hiki ke hana me nā mea ʻē aʻe me ka ʻole o ka mālama ʻana ʻoi aku ka maikaʻi ma mua o ka huahana o MOCA (Mocha).
3. Hoʻohana ʻia no ka paʻi ʻana i ka polyurethane rubber scraper, aila paipu hoʻomaʻemaʻe scraper, a me nā mea ʻē aʻe, e hoʻomaikaʻi i ka pale ʻana o ka aila o ka polyurethane, a haʻahaʻa hoʻi ka nui o ka hoʻonui ʻana.
4. Eia kekahi, hoʻohana nui ʻia i ka ʻoihana textile, pepa a me ka paʻi. Hiki ke ʻōlelo ʻia he mākeke ākea kona mai ka ʻoihana mokulele a me ka ʻoihana aerospace i ka ʻoihana kīwila ākea.
