Tšebeliso
4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA) ke motsoako oa lintho tse phelang, 'me litsela tsa eona tsa mantlha tsa ts'ebeliso ke tse latelang:
- Ho kopanngoa ha Thepa ea Polyurethane: MOCA ke extender ea bohlokoa ea ketane bakeng sa li-elastomer tsa polyurethane. Tlhahisong ea polyurethane, li-prepolymer tsa isocyanate li hloka ho arabela le li-extender tsa ketane ho etsa li-polymer tsa polyurethane tse boima bo phahameng. MOCA e na le reactivity e phahameng haholo ka li-isocyanate, e ka atolosang ketane ea limolek'hule tsa polyurethane ka katleho le ho ntlafatsa boima, matla, ho hanyetsa ho tsofala, ho hanyetsa ho taboha le litšobotsi tse ling tsa thepa. E sebelisoa hangata tlhahisong ea lihlahisoa tsa polyurethane elastomer tse jereng mojaro o moholo, joalo ka lipoleiti tsa sieve, li-roller tsa rabara, litiiso, jj. tse sebelisoang liindastering tse kang merafo, tšepe le peterole. Lihlahisoa tsena li hloka ho ba le khanyetso e ntle ea ho tsofala le thepa ea mechini.
- Moemeli oa ho Folisa bakeng sa Li-Resins tsa Epoxy: MOCA e ka sebelisoa e le moemeli oa ho folisa bakeng sa li-resins tsa epoxy. E feta karabelong e hokahaneng le li-resins tsa epoxy ho theha sebopeho sa marang-rang sa mahlakore a mararo, ka hona e folisa li-resins tsa epoxy. Li-resins tsa epoxy tse folisitsoeng li na le thepa e ntle ea mechini, khanyetso ea k'hemik'hale ea ho bola, le khanyetso ea mocheso. Hangata e sebelisoa tlhahisong ea metsoako e meng ea epoxy e nang le litlhoko tse phahameng tsa ts'ebetso, joalo ka masimong a lisebelisoa tsa ho etsa lipitsa tsa elektroniki le liaparo tsa fatše. Lisebelisoa tsa ho etsa lipitsa tsa elektroniki li hloka ho sireletsa likarolo tsa elektroniki tsa kahare tikolohong ea kantle. Resins ea epoxy e folisitsoeng ka ho nka karolo ha MOCA e ka fana ka tšireletso e ntle ea ho tiisa le ea mechini. Liaparo tsa fatše tsa epoxy li hloka ho ba le thepa e kang khanyetso ea ho tsofala le khanyetso ea ho bola ho fihlela litlhoko tsa ts'ebeliso ea libaka tse kang li-workshop tsa indasteri le libaka tsa ho paka makoloi.
