Dimeryl Diisocyanate DDI CAS NO. 68239-06-5
NOke aliphatic diisocyanate e ikhethang e ka sebelisoang ho lokisa lipolymer tse nang le metsoako e nang le hydrogen e sebetsang. Ke motsoako oa ketane e telele e nang le mokokotlo oa 36-carbon dimer fatty acid. Mohaho o ka sehloohong oa ketane o fana kaNOho feto-fetoha ha maemo ho phahameng, ho hanyetsa metsi le chefo e tlase ho li-isocyanate tse ling tsa aliphatic.NOke mokelikeli o tlaase oa viscosity o qhibilihang habonolo ho lihlapolli tse ngata tsa polar kapa tse seng polar. Hobane ke aliphatic isocyanate, e na le litšobotsi tsa ho se mosehla. E na le melemo e mengata ea chefo e tlase, e bonolo ho e sebelisa, e qhibiliha ka har'a lihlapolli tse ngata, nako ea karabelo e laolehang le kutloisiso e tlase ea metsi. Ke mofuta o tloaelehileng oa li-isocyanate tse tala tse ka sebelisoang haholo ho phethela masela, li-elastomers, likhomaretsi le li-sealants, litlolo, li-inks le masimo a mang a sesole le a sechaba.
1. Lesela: DDI ea rona e nang le metsi habonolo hore e be emulsion ea metsi, e entseng hore lesela le be le boreleli, le be bonolo, le se ke la thibela metsi.
2. PU resin le Polyurea resin, ho sebelisa DDI e ka ba le preformance ea bao e seng mosehla, e babatsehang resilience, le extensile, phahameng thata, tlaase metsi a utloahalang, le molemo anti-abrasivenesss, anti-chemical solvent , le anti-tlase mocheso.
3. Itšoare kaHTPBho lumellana hantle le ho sebetsa hape, PU e hlahisoang e ka ba e sa tsitsang ka mokhoa o makatsang, ha ho hlokahale moemeli oa polasetiki.
4. Ho roala. Ho roala ha DDI polyurea ka matla a matle haholo le bopaki ba boemo ba leholimo, tse khomarelang habonolo tšepe le lehong ntle le ho robeha.
