DDI, CAS: 68239-06-5 Dimeryl Diisocyanate, Dimeryl-di-isocyanate

Tlhaloso e Khutšoanyane:

Re thehile dimer acid diisocyanate (DDI) e nang le chefo e tlase ka ho sebelisa lisebelisoa tse tala tse nchafalitsoeng le theknoloji e ncha ho arabela chefo e phahameng ea li-isocyanate tse sebelisoang hangata 'marakeng oa lehae le kotsi e tebileng' meleng oa motho.Matšoao a fihlile boemong ba boemo ba sesole sa US (MIL-STD-129).Molek'hule ea isocyanate e na le ketane e telele ea 36-carbon dimerized fatty acid, 'me e metsi mocheso oa kamore.E na le melemo e mengata joalo ka chefo e tlase, ts'ebeliso e bonolo, e qhibilihang ka har'a li-solvents tse ngata, nako ea karabelo e laolehang le kutloisiso e tlase ea metsi.Ke mofuta o ikhethileng oa isocyanate o ka sebelisoang haholo libakeng tsa sesole le tsa sechaba, joalo ka ho phethela masela, li-elastomers, likhomaretsi le li-sealants, likoti, li-inks, jj.


Lintlha tsa Sehlahisoa

Li-tag tsa Sehlahisoa

DDI ke "aliphatic diisocyanate" e ikhethang e ka kopanngoang le metsoako e sebetsang e nang le haedrojene ho lokisa lipolima.Ke motsoako oa ketane e telele e nang le mokokotlo oa 36-carbon dimerized fatty acid.Sebopeho se seholo sa ketane se fa DDI ho fetoha ha maemo ho phahameng, ho hanyetsa metsi le chefo e tlaase ho feta li-isocyanate tse ling tsa aliphatic.DDI ke mokelikeli o nang le viscosity e tlase, 'me o qhibiliha ha bonolo ho lihlapolli tse ngata tsa polar kapa tse seng polar.Hobane ke aliphatic isocyanate, e na le thepa e seng mosehla.

Tšebeliso le molemo oa DDI ke ofe?

DDI e ka sebelisoa ho lokisa li-polymers tse nang le metsoako e 'meli kapa ho feta ea haedrojene e sebetsang, e ka sebelisetsoang ho lokisa li-elastomer tsa polyurethane (urea) tse nang le thepa e khethehileng, ho phekola li-propellants tse tiileng tsa rocket, li-adhesives, sealants, ho qeta holim'a lesela, pampiri, letlalo le lesela. Moemeli oa ho thibela metsi, lisebelisoa tsa elektroniki, lehong le thibelang metsi, joalo-joalo.

1. DDI e na le menyetla ea ts'ebeliso ea kalafo ea ho leleka metsi a masela le ts'ebetso e bonolo.Ho bonolo ho theha emulsion ea metsi e tsitsitseng ka metsi, e ka fanang ka masela ka ho feto-fetoha ha nako e telele;e le lesela le thibelang metsi, le na le phello e ntle ea ho thibela metsi 'me le ka boela la ntlafatsa phello ea lesela le entsoeng ka lesela la fluoride le lelekang oli.
2. Li-resin tsa polyurethane le li-polyurea resin tse entsoeng ka DDI li na le 'mala o se nang mosehla, elasticity e babatsehang le ductility, matla a phahameng, kutloisiso e tlaase ea metsi, le ho hanyetsa hantle ha abrasion, k'hemik'hale ea ho qhibiliha ha lik'hemik'hale le ho hanyetsa mocheso o tlaase.
3.DDI e na le tšebelisano e ntle haholo le ts'ebetso e ts'oanang le hydroxyl-terinated polybutadiene, 'me polymer e lokisitsoeng ntle le polasetiki e na le boima bo tlase bo sa tloaelehang.
4. Liaparo tsa polyurea tse thehiloeng ho DDI li khomarela hantle tšepe le lehong, ha li na mapetsong, 'me li bontša thepa e babatsehang ea ho tsitsisa, thepa ea ho khomarela le ho hanyetsa boemo ba leholimo.
