Kodi Dimethyl thio-toluene Diamine DMTDA ndi chiyani?

Dimethyl thio-toluene diamine (DMTDA), yokhala ndi nambala ya CAS 106264-79-3, ndi chinthu chofunikira kwambiri chachilengedwe. Maatomu a sulfure omwe ali mu molekyulu ya amine ya DMTDA amatha kuwonjezera luso logwirizana ndi zitsulo, komanso nthawi yomweyo amapereka mankhwala ochiritsidwa ndi kukana bwino kwa hydrolysis komanso kukana dzimbiri kwa mankhwala.

DMTDA ndi mtundu watsopano wa polyurethane elastomer curing and crosslinking agent, momwe muli ma isomers awiri makamaka, omwe ndi osakaniza a 2,4 - ndi 2,6 - dimethylthiotoluene diamine (chiŵerengero chake ndi pafupifupi 77 ~ 80/17 ~ 20). Poyerekeza ndi MOCA yomwe imagwiritsidwa ntchito kwambiri, DMTDA ndi madzi okhala ndi viscosity yochepa pa kutentha kwabwinobwino, omwe angagwiritsidwe ntchito pomanga pa kutentha kochepa, ndipo ali ndi mankhwala ofanana ndi otsika.

Kufotokozera

Maonekedwe	Madzi opepuka achikasu owonekera bwino
Kuyesa kwa Diamine (GC)	≥95%
Mtengo wa Mtundu (Gardner)	≤8
Kuyesa kwa TDA	≤0.1%
Mtengo wa Amine	525-535
Kuchuluka kwa Madzi	≤0.1%

Kugwiritsa ntchito

1. Dimethyl thio-toluene diaminendi mtundu watsopano wa mankhwala ochiritsira madzi a polyurethane elastomer. Dmtda amine imagwiritsidwa ntchito kwambiri popangira polyurethane casting, coating, RIM, SPUA, polyurethane tire ndi zomatira zokulitsa unyolo kapena cross-linking, komanso ndi mankhwala ochiritsira a epoxy resin.

2. Dmtda ethacure 300 ndi mankhwala ochiritsira utomoni wa epoxy ndipo angagwiritsidwe ntchito kupititsa patsogolo magwiridwe antchito a utomoni wa epoxy.

3. Monga hardener, ikawonjezedwa ku TDI ndi MTDI two-liquid polyurethane elastomers, iyenera kuwonjezedwa pamlingo wa 10%. Mu zomangamanga ndi mafakitale aboma, dmtda amine nthawi zambiri imagwiritsidwa ntchito ngati chowonjezera pakuphimba moto (pamwamba ndi pakhoma lam'mbali), kuteteza dzimbiri kwa zinthu zachitsulo (kuphimba pakhoma lamkati la chitoliro chachitsulo), ndi zina. Chopangidwa ndi polyurethane chomwe chingagwirizane ndi zinthu zina popanda chithandizo chilichonse ndi chapamwamba kuposa chopangidwa ndi hardener ya MOCA (Mocha).

4. Amagwiritsidwa ntchito popaka chotsukira cha rabara chosindikizira polyurethane, chotsukira chitoliro cha mafuta, ndi zina zotero, kuti awonjezere kukana kwa mafuta a polyurethane, ndipo kuchuluka kwa kukula kwake nakonso ndi kochepa.

5. Kuphatikiza apo, dmtda amineimagwiritsidwa ntchito kwambiri m'mafakitale opanga nsalu, mapepala ndi osindikiza. Dimethyl thio-toluene diamine inganenedwe kuti ili ndi msika waukulu kuyambira makampani opanga ndege ndi ndege mpaka makampani wamba.

Ubwino wathu

1. Zomwe zili mu DMTDA yathu zimaposa miyezo ya makampani, ndipo gulu lililonse nthawi zonse limafika pa 96%.

2. Pokhala ndi amine yokwera kuposa miyezo yamakampani, gulu lililonse limapeza 530mgKOH/g mosalekeza, zomwe zimapangitsa kuti pakhale kuchira kwabwino kwambiri.

3. Tili ndi mphamvu zokwanira zopangira komanso zinthu zatsopano, tikutsimikizira kuti dongosolo lidzakwaniritsidwa mwachangu, ndipo kutumiza kudzachitika mkati mwa masiku 5 ogwira ntchito.

4. Kupatula ma CD athu olemera makilogalamu 200, timapereka njira zokonzera zinthu mwamakonda komanso ntchito zosindikiza ma logo zomwe zikugwirizana ndi zosowa zanu.
