Dimethyl thio-toluene Diamine DMTDA ke eng?

DMTDA ke mofuta o mocha oa polyurethane elastomer e phekolang le e kopanyang lintho, eo ho eona ho nang le li-isomers tse peli haholo, e leng motsoako oa 2,4 - le 2,6 - dimethylthiotoluene diamine (karolelano e ka ba 77~80/17~20). Ha e bapisoa le MOCA e sebelisoang ka tloaelo, DMTDA ke mokelikeli o nang le viscosity e tlaase mocheso o tloaelehileng, o ka sebelisoang bakeng sa ts'ebetso ea kaho ka mocheso o tlaase, 'me o na le lik'hemik'hale tse tlaase.

Kopo

1. Ke mofuta o mocha oa pheko ea metsi bakeng sa polyurethane elastomer. E sebelisoa haholo ho lahla polyurethane, ho roala, RIM, SPUA, thaere ea polyurethane le sekhomaretsi bakeng sa katoloso ea ketane kapa ho hokahanya, hape ke moemeli oa pheko bakeng sa resin ea epoxy.

2. E le ho thatafala, ha e kenngoa ho TDI le MTDI tse peli tsa metsi a polyurethane elastomers, e tlameha ho kenngoa ka tekanyo ea 10%. Ka indasteri ea kaho le ea sechaba, hangata e sebelisoa e le tlatsetso bakeng sa ho roala ha mollo (lera le ka holimo le lerako le lehlakoreng), ts'ireletso ea kutu ea thepa ea tšepe (ho roala leboteng le ka hare la phala ea tšepe), le likarolo tse ling. Sehlahisoa sa polyurethane se ka sebetsanang le lintho tse ling ntle le phekolo leha e le efe se phahametse sehlahisoa sa MOCA (Mocha) hardener.
3. E sebelisoa bakeng sa polyurethane khatiso ea rabara scraper, peipi ea oli e hloekisang scraper, joalo-joalo, ho ntlafatsa ho hanyetsa oli ea polyurethane, le tekanyo ea ho atolosa molumo le eona e tlaase.
4. Ho phaella moo, e sebelisoa haholo indastering ea masela, ea pampiri le ea khatiso. Ho ka boleloa hore e na le 'maraka o pharaletseng ho tloha indastering ea lifofane le lifofane ho ea indastering ea sechaba ka kakaretso.
