He aha ka Dimethyl thio-toluene Diamine DMTDA?

ʻO Dimethyl thio-toluene diamine (DMTDA), me ka helu CAS 106264-79-3, he hui organik koʻikoʻi. Hiki i nā ʻātoma sulfur i loko o ka molekole amine DMTDA ke hoʻoikaika i ka hiki ke hoʻohui me nā metala, a i ka manawa like e hāʻawi i ka huahana i hoʻōla ʻia me ke kūpaʻa hydrolysis maikaʻi loa a me ke kūpaʻa corrosion kemika.

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

Noi

1. ʻO Dimethyl thio-toluene diaminehe ʻano hou o ka mea hoʻōla wai no ka polyurethane elastomer. Hoʻohana nui ʻia ʻo Dmtda amine i ka hoʻolei polyurethane, ka uhi ʻana, RIM, SPUA, ka huila polyurethane a me ka mea hoʻopili no ka hoʻonui ʻana i ke kaulahao a i ʻole ke kāpili ʻana, a he mea hoʻōla nō hoʻi no ka epoxy resin.

2. He mea hoʻōla ʻo Dmtda ethacure 300 no ka resin epoxy a hiki ke hoʻohana ʻia e hoʻomaikaʻi i ka hana o ka resin epoxy.

3. Ma ke ʻano he mea paʻakikī, i ka wā e hoʻohui ʻia ai i nā elastomers polyurethane ʻelua-wai TDI a me MTDI, pono e hoʻohui ʻia ma ka helu o 10%. I ke kūkulu ʻana a me ka ʻoihana kīwila, hoʻohana pinepine ʻia ʻo dmtda amine ma ke ʻano he mea hoʻohui no ka uhi pale ahi (papa luna a me ka paia ʻaoʻao), ka pale ʻana i ka pala o nā mea metala (ka uhi ʻana ma ka paia o loko o ka paipu hao), a me nā ʻano ʻē aʻe. ʻOi aku ka maikaʻi o ka huahana polyurethane hiki ke hana me nā mea ʻē aʻe me ka ʻole o ka mālama ʻana ma mua o ka huahana o ka mea paʻakikī MOCA (Mocha).

4. Hoʻohana ʻia no ka paʻi polyurethane rubber scraper, aila pipe cleaning scraper, a pēlā aku, e hoʻomaikaʻi i ke kūpaʻa ʻaila o ka polyurethane, a haʻahaʻa hoʻi ka nui o ka hoʻonui ʻana.

5. Eia kekahi, ʻo dmtda aminehoʻohana nui ʻia i nā ʻoihana lole, pepa a me ka paʻi. Hiki ke ʻōlelo ʻia ʻo Dimethyl thio-toluene diamine he mākeke ākea kona mai ka ʻoihana mokulele a me ka aerospace a i ka ʻoihana kīwila maʻamau.

ʻO kā mākou mau pono

1. ʻOi aku ka nui o kā mākou ʻike DMTDA ma mua o nā kūlana ʻoihana, me kēlā me kēia pūʻulu e hōʻea mau ana ma luna o 96%.

2. Ke hōʻike nei i kahi waiwai amine kiʻekiʻe aʻe ma mua o nā pae hoʻohālikelike o ka ʻoihana, hoʻokō paʻa kēlā me kēia pūʻulu i 530mgKOH/g, e hāʻawi ana i ka hana hoʻōla koʻikoʻi.

3. Me ka lawa o ka hiki ke hana a me ka waihona hou, hōʻoia mākou i ka hoʻokō wikiwiki ʻana i nā kauoha, me ka hiki ke hoʻouna ʻia i loko o 5 mau lā hana.

4. Ma waho aʻe o kā mākou ʻōpala pahu 200kg maʻamau, hāʻawi mākou i nā koho ʻōpala maʻamau a me nā lawelawe paʻi logo i hana ʻia no kāu mau koi kikoʻī.
