Dimethyl thio-toluene Diamine DMTDA ke eng?

Dimethyl thio-toluene diamine (DMTDA), e nang le nomoro ea CAS 106264-79-3, ke motsoako oa bohlokoa oa lintho tse phelang. Liathomo tsa sebabole tse molek'huleng ea amine ea DMTDA li ka ntlafatsa bokhoni ba ho hokahanya le litšepe, 'me ka nako e ts'oanang li fa sehlahisoa se phekotsoeng khanyetso e ntle ea hydrolysis le khanyetso ea ho bola ha lik'hemik'hale.

DMTDA ke mofuta o mocha oa polyurethane elastomer curing le crosslinking agent, moo ho nang le li-isomer tse peli haholo-holo, e leng motsoako oa 2,4 - le 2,6 - dimethylthiotoluene diamine (karolelano ke hoo e ka bang 77 ~ 80/17 ~ 20). Ha e bapisoa le MOCA e sebelisoang hangata, DMTDA ke mokelikeli o nang le viscosity e tlase mochesong o tloaelehileng, o ka sebelisoang bakeng sa ts'ebetso ea kaho mochesong o tlase, 'me o na le se lekanang le lik'hemik'hale tse tlase.

Kopo

1. Dimethyl thio-toluene diamineke mofuta o mocha oa moemeli oa ho phekola metsi bakeng sa polyurethane elastomer. Dmtda amine e sebelisoa haholo ho lahla polyurethane, ho koahela, RIM, SPUA, thaere ea polyurethane le sekhomaretsi bakeng sa katoloso ea ketane kapa ho hokahanya, 'me hape ke moemeli oa ho phekola resin ea epoxy.

2. Dmtda ethacure 300 ke sesebelisoa sa ho folisa resin ea epoxy 'me se ka sebelisoa ho ntlafatsa ts'ebetso ea resin ea epoxy.

3. Jwalo ka ha e le hardener, ha e eketswa ho TDI le MTDI two-liquid polyurethane elastomers, e tlameha ho eketswa ka sekgahla sa 10%. Indastering ya kaho le ya setjhaba, dmtda amine hangata e sebediswa e le sehlomathiso bakeng sa ho kwahela mollo (karolo e ka hodimo le lebota le ka thoko), tshireletso ya mafome ya thepa ya tshepe (ho kwahela leboteng le ka hare la phaephe ya tshepe), le dikarolo tse ding. Sehlahiswa sa polyurethane se ka arabelang le dintho tse ding ntle le kalafo efe kapa efe se feta sehlahiswa sa hardener ya MOCA (Mocha).

4. E sebelisoa bakeng sa sekere sa rabara sa khatiso ea polyurethane, sekere sa ho hloekisa liphaephe tsa oli, jj., ho ntlafatsa khanyetso ea oli ea polyurethane, 'me sekhahla sa katoloso ea bophahamo le sona se tlase.

5. Ho phaella moo, dmtda aminee sebelisoa haholo indastering ea masela, pampiri le khatiso. Dimethyl thio-toluene diamine e ka boleloa hore e na le 'maraka o pharaletseng ho tloha indastering ea lifofane le ea lifofane ho ea indastering e akaretsang ea sechaba.

Melemo ea rona

1. Dikahare tsa rona tsa DMTDA di feta maemo a indasteri hole, mme sehlopha se seng le se seng se fihlella ho feta 96%.

2. Ka ho ithorisa ka boleng ba amine bo phahameng ho feta litekanyetso tsa indasteri, sehlopha se seng le se seng se fihlella 530mgKOH/g ka botsitso, se fana ka ts'ebetso e ikhethang ea ho phekola.

3. Ka bokgoni bo lekaneng ba tlhahiso le thepa e ncha, re netefatsa phethahatso e potlakileng ea odara, ka phano e ka fihlellehang matsatsing a 5 a mosebetsi.

4. Ka ntle ho sephutheloana sa rona sa meropa se tloaelehileng sa 200kg, re fana ka likhetho tsa ho paka tse ikhethileng le lits'ebeletso tsa ho hatisa matšoao tse etselitsoeng litlhoko tsa hau tse ikhethileng.
