Dimeryl diisocyanate (DDI) ke aliphatic e ikhethang (dimer fatty acid diisocyanate) diisocyanate e ka sebelisoang le metsoako e nang le hydrogen e sebetsang ho lokisa lihlahisoa tse fokolang tsa boima ba limolek'hule kapa li-polymers tse khethehileng.
DDI ke motsoako o molelele oa ketane e nang le ketane e kholo ea dimeric fatty acids e nang le liathomo tse 36 tsa carbon.Sebopeho sena sa mokokotlo se fa DDI ho tenyetseha ho holimo, ho hanyetsa metsi le chefo e tlase ho feta li-isocyanate tse ling tsa aliphatic.
DDI ke mokelikeli o tlase oa viscosity o qhibilihang habonolo lihlaolong tse ngata tsa polar kapa nonpolar.

DDI e ka sebelisoa ho propellant e tiileng ea rocket, ho qeta lesela, pampiri, letlalo le lesela la lesela, phekolo ea ho boloka lehong, ho pitsa ka motlakase le ho lokisa thepa e khethehileng ea polyurethane (urea) elastomers, sekhomaretsi le sealant, joalo-joalo.
DDI e na le lintho tse nang le chefo e tlase, ha e na mosehla, e qhibiliha ka har'a lihlapolli tse ngata tsa manyolo, ha e na metsi a tlase le viscosity e tlase.
Indastering ea masela, DDI e bonts'a tebello e ntle ea ts'ebeliso ho thepa e thibelang metsi le ho nolofatsa masela.Ha e utloele metsi haholo ho feta li-isocyanate tse nkhang hamonate 'me e ka sebelisoa ho lokisa li-emulsion tse tsitsitseng tsa metsi.DDI e ka ntlafatsa phello ea ho thibela metsi le ho thibela oli bakeng sa masela a fluorinated.Ha e sebelisoa e kopane, DDI e ka ntlafatsa haholo thepa ea masela e thibelang metsi le oli.
DDI, e lokisitsoeng ho tloha dimer fatty acids, ke mofuta o tloaelehileng oa isocyanate o motala, o ka nchafatsoang ka likokoana-hloko.Ha ho bapisoa le universal isocyanate TDI, MDI, HDI le IPDI, DDI ha e chefo ebile ha e hlasimolle.
Ho tšoara: Qoba ho kopana le metsi.Etsa bonnete ba hore ho na le moea o motle mosebetsing.
Polokelo: Boloka ka lijaneng tse koetsoeng ka thata, tse pholileng ebile li omme.
Lintlha tsa lipalangoang: ha li laoloe joalo ka ntho e kotsi.
