I-Diisocyanate (DDI) iyi-diisocyanate ehlukile ye-aliphatic ene-36 carbon atom dimer fatty acid backbone. Isakhiwo sinikeza i-DDI ukuguquguquka okungcono nokunamathela kunezinye i-aliphatic isocyanate. I-DDI inezakhiwo ezinobuthi obuphansi, ayinabo ubuphuzi, iyancibilika ezinyibilikisini eziningi eziphilayo, ayizweli emanzini kakhulu futhi ayina-viscosity. I-DDI uhlobo lwe-Isocyanate yokusebenza okubili, ingasebenza nama-hydrogen compounds amabili noma ngaphezulu asebenzayo ukwenza i-polymer. I-DDI ingasetshenziswa ku-rocket propellant eqinile, ukuqeda indwangu, iphepha, ukulahla isikhumba nendwangu, ukwelashwa kokulondolozwa kokhuni, ukupheka ngogesi kanye nokulungiselela izakhiwo ezikhethekile ze-polyurethane (urea) elastomers, i-adhesive kanye ne-sealant, njll.

Embonini yezindwangu, i-DDI ikhombisa ukusetshenziswa okuhle kakhulu ezimpahleni ezivimbela amanzi nezithambisa izindwangu. Ayizweli kakhulu emanzini kune-isocyanates enuka kamnandi futhi ingasetshenziswa ukulungiselela ama-emulsion aqinile emanzini.

Ukusetshenziswa kwe-0.125%DDI kunikeza indwangu ubuthambile obuhlala isikhathi eside; Izindwangu eziphathwe ngezithambisi-ndlela ze-cationic ezingagugi zinokuguquguquka okufanayo ngemva kokuwashwa izikhathi ezingu-26. Isithambisi-manzi sendwangu sisebenzisa i-1%DDI sinomphumela ofanayo noma ongcono wokuxosha amanzi njengesithambisi-manzi se-pyridine esinamafutha (ukuhlolwa kwe-AATCC).

I-DDI ingathuthukisa umphumela we-repellent wamanzi kanye ne-oyela ezindwangu ezine-fluorine. Uma isetshenziswa ndawonye, ​​i-DDI ingathuthukisa kakhulu izakhiwo zendwangu ezivimbela amanzi kanye ne-oyela.

Kokubili ukuhlolwa kwelabhorethri kanye nokuhlolwa kwensimu kukhombisile ukuthi i-DDI inokumelana okungcono nokuwashwa kanye nokuhlanza okomile kunezithasiselo ze-fluoride noma zendwangu ezifana nama-antistatic agents.

I-DDI, elungiselelwe ngama-fatty acid e-dimer, iyinhlobo ejwayelekile eluhlaza, evuselelekayo ephilayo. Uma iqhathaniswa ne-isocyanate ebanzi i-TDI, i-MDI, i-HDI kanye ne-IPDI, i-DDI ayinabo ubuthi futhi ayivuseleli. Ngokuthandwa kwezinto zokusetshenziswa ze-dimeric acid eShayina kanye nokunaka kwabantu okwandayo emnothweni wokuvikelwa kwemvelo onekhabhoni ephansi kanye nentuthuko esimeme, ukubaluleka kokusebenzisa izinto zokusetshenziswa ezivuselelekayo ephilayo ukulungiselela i-DDI kuye kwavela kancane kancane, okubaluleke kakhulu ekukhuthazeni intuthuko yemboni ye-polyurethane.
