Kodi Dimethyl thio-toluene Diamine DMTDA ndi chiyani?

DMTDA ndi mtundu watsopano wa polyurethane elastomer kuchiritsa ndi crosslinking wothandizira, momwe muli makamaka isomers awiri, ndicho osakaniza 2,4 - ndi 2,6 - dimethylthiotoluene diamine (chiŵerengero ndi za 77~80/17~20). Poyerekeza ndi MOCA ambiri ntchito, DMTDA ndi madzi ndi otsika mamasukidwe akayendedwe pa kutentha yachibadwa, amene angagwiritsidwe ntchito pomanga ntchito pa kutentha otsika, ndipo ali otsika ofanana mankhwala.

Kugwiritsa ntchito

1. Ndi mtundu watsopano wa mankhwala amadzimadzi ochiritsa polyurethane elastomer. Amagwiritsidwa ntchito kwambiri poponya polyurethane, zokutira, RIM, SPUA, tayala la polyurethane ndi zomatira pakukulitsa unyolo kapena kulumikizana ndi mtanda, komanso ndi mankhwala ochiritsira utomoni wa epoxy.

2. Monga chowumitsa, chikawonjezedwa ku TDI ndi MTDI ma elastomers amadzimadzi awiri a polyurethane, ayenera kuwonjezeredwa pa mlingo wa 10%. Pomanga ndi zomangamanga, nthawi zambiri amagwiritsidwa ntchito ngati chowonjezera chotchingira moto (wosanjikiza pamwamba ndi khoma lakumbali), chitetezo cha dzimbiri cha zida zachitsulo (zopaka pakhoma lamkati la chitoliro chachitsulo), ndi zina. Chopangidwa ndi polyurethane chomwe chimatha kuchita ndi zinthu zina popanda chithandizo chilichonse chimakhala chapamwamba kuposa cha MOCA (Mocha) chowumitsa.
3. Amagwiritsidwa ntchito pa polyurethane yosindikiza rabara scraper, mafuta otsuka scraper, ndi zina zotero, kuti apititse patsogolo kukana kwa mafuta a polyurethane, ndipo kuchuluka kwa voliyumu kumakhalanso kochepa.
4. Kuphatikiza apo, amagwiritsidwa ntchito kwambiri m'makampani opanga nsalu, mapepala ndi osindikiza. Titha kunena kuti ili ndi msika wotakata kuchokera kumakampani opanga ndege ndi ndege kupita kumakampani wamba.
