Diethyltoluenediamine (DETDA) CAS 68479-98-1
Diethyl-toluene-diamine (DETDA), nomoro ea CAS 68479-98-1 ke sesebelisoa sa ho phekola metsi a aromatic diamine, se tšoanang le Ethacure 100 le DETDA 80, bakeng sa polyurea le polyurethane (PU).
Kaha ke sesebelisoa se sebetsang hantle sa ho atolosa ketane bakeng sa lits'ebetso tsa polyurethane, DETDA ke tharollo e ntle ka theko ea eona e tlase le thepa e ntle haholo, haholo-holo bakeng sa RIM (reaction injection molding) le SPUA (Spray Polyurea Elastomer). DETDA e nolofalletsa ho folisa polyurethane/epoxy ka nako e khuts'oane haholo, e se ke ea thella ka metsotsoana 'me e koala bokaholimo ka ho phethahetseng ho sireletsa fatše, mahlakore a ka pele, marulelo le marokho. Habohlokoa le ho feta, polyurea ea mofuta oa DETDA e koahela le ho koala bokaholimo bo otlolohileng ka metsotsoana e seng mekae ntle le ho oa.
DETDA ke sehokelo se atileng haholo sa ketane indastering ea polyurethane, e na le viscosity e tlase, e ka sebetsoa habonolo ebile e na le botsoalle tikolohong. Kaha ke mofuta oa mokelikeli, DETDA e ka sebetsoa mochesong oa kamore 'me ea phekoloa hantle. Ho feta moo, li-elastomer tsa mofuta oa DETDA li na le matla a phahameng a ho mamella joaloka tsa mofuta oa MOCA. Ho sa le joalo, ho na le chefo e fokolang le lerōle fekthering ea tlhahiso ha ho bapisoa le MOCA.
Ho tšoana le tšebeliso ea eona ho polyurethane le polyurea e le lintho tse phekolang, DETDA e sebelisoa e le sesebelisoa sa ho tiisa le ho kopanya li-resin tsa epoxy. Lihlopha tsa eona tse peli tsa amine li arabela ka lihlopha tse 'ne tsa epoxy, 'me li bile li theha setsi sa ho kopanya mocheso o phahameng hammoho le bisphenol A. Ka ho fetola tekanyo, DETDA e ka fana ka karabelo e potlakileng le sebaka sa ho kopanya li-cross-linking ha ho hlokahala.
Ha ho bapisoa le DMTDA, DimethylthioToluene Diamie, ha ho na monko o sa thabiseng oa sebabole 'me lihlahisoa tse phehiloeng li thata haholo ka thepa e betere ea' mele.
DETDA e sebelisoa haholo e le sesebelisoa sa ho phekola bakeng sa sistimi ea ho fafatsa ea polyurethane/polyuria bakeng sa tšireletso e tšoarellang nako e telele ea libaka tsohle. Ka thepa ea eona ea ho phekola ka potlako, DETDA e sebelisoa haholo kahong le thepa ea kaho. Ke tharollo e phethahetseng e hlokang ho koaheloa/ho koaloa ka potlako, ka katleho le ka nako e telele.
Bakeng sa bao ba amehang ho fafatseng dikoahelo tsa polyurea, polyurethanes, metsoako le epoxy resins, ho tla ba thata hore o fumane di-substitute tsa DETDA tse lumellanang le ditlhoko tsa hao tsa ho sebetsana le tsona. Lebelo la yona le ikgethang la ho fola le etsa hore e be ya mofuta oo.
Ho feta moo, DETDA e boetse e sebediswa e le moemedi wa ho fodisa/ho kopanya polyurethane le epoxy resin, e leng antioxidant ya epoxy resin, oli ya diindasteri le ditlolo. Ho feta moo, Diethyl-toluene-diamine e sebediswa e le karolo e bohareng ya tlhahiso ya manyolo.
Pakete: 20kg, 200kg/teramo ya tshepe. kapa TANK ya IBC.
Polokelo le lipalangoang: Qoba ho kopana le metsi. Boloka hole le khanya ea letsatsi.
