| Sehlahisoa: | Dimeryl diisocyanateEA-1410-DDI | CAS Nomoro. | 68239-06-5 |
| Tsela ea molek'hule: | C36H66N2O2 | EINECS: | 269-419-6 |
Litlhokomelo tsa ho Tšoara le ho Boloka: BOLOKA SEKHUSETSI SE KWETSE HABANE HA U SEBELISA. LEBENKA LEBAKENG.
Dimeryl diisocyanate (DDI) ke aliphatic e ikhethang (dimer fatty acid diisocyanate) diisocyanate e ka sebelisoang ka metsoako e nang le haedrojene e sebetsang ho lokisa lihlahisoa tse tlase tsa limolek'hule kapa li-polymeri tse khethehileng.
DDI ke motsoako oa ketane e telele e nang le ketane e kholo ea mafura a mafura a nang le liathomo tsa khabone tse 36. Sebopeho sena sa mokokotlo se fa DDI maemo a fetohang a maemo, ho hanela metsi le chefo e tlase ho feta tse ling tsa isocyanate tsa aliphatic.
DDI ke mokelikeli o tlase oa viscosity o ka qhibilihang habonolo ho li-solvent tse ngata tsa polar kapa tse seng tsa polar.

1) lintlha tsohle tsa tekheniki tse bontšitsoeng kaholimo ke tsa hau.
2) litlhaloso tse ling lia amoheleha bakeng sa puisano e tsoelang pele.
DDI e ka sebelisoa ho rokete e tiileng ea rokete, ho qeta masela, pampiri, letlalo le lesela le lelekang, kalafo ea lehong, pitsa ea motlakase le ho hlophisa thepa e khethehileng ea li-elastomers tsa polyurethane (urea), sekhomaretsi le sekontiri, jj.
DDI e na le litšobotsi tse nang le chefo e tlase, ha e na mosehla, e qhibiliha ho li-solvents tse ngata tse nang le manyolo, metsi a fokolang haholo le viscosity e tlase.
Indastering ea masela, DDI e bonts'a tebello e ntle ea ts'ebeliso ho thepa e sa keneleng metsi le ho nolofatsa masela. Ha e tsotelle metsi ho feta li-isocyanate tse nkhang hamonate 'me e ka sebelisoa ho lokisa li-emulsions tse tsitsitseng tse nang le metsi. DDI e ka ntlafatsa phello ea metsi a lelekang metsi le a lelekang oli bakeng sa masela a nang le fluorine. Ha e sebelisoa e kopane, DDI e ka ntlafatsa haholo masela a lelekang metsi le a lelekang oli.
DDI, e lokiselitsoeng ho tsoa ho mafura a mafura a acid, ke mofuta o tloaelehileng oa botala, o ka nchafatsoang ke bio isocyanate. Ha e bapisoa le bokahohle ba isocyanate TDI, MDI, HDI le IPDI, DDI ha e chefo ebile ha e susumetse.
Ho sebetsana le eona: Qoba ho kopana le metsi. Etsa bonnete ba hore moea o kenella hantle mosebetsing.
Sesebelisoa: Boloka ka har'a lijana tse koetsoeng ka thata, li pholile ebile li omme.
