I-Diisocyanate (DDI) iyi-aliphatic diisocyanate eyingqayizivele ene-36 carbon athomu dimer fatty acid backbone.Isakhiwo sinikeza i-DDI ukuguquguquka okungcono nokunamathela kunezinye isocyanate aliphatic.I-DDI inezindawo ezinobuthi obuphansi, ayinawo umbala ophuzi, incibilika kuzincibilikisi eziningi eziphilayo, ukuzwela kwamanzi aphansi kanye ne-viscosity ephansi.I-DDI iwuhlobo lwemisebenzi emibili ye-Isocyanate, ingasebenza nezinhlanganisela ezimbili noma ngaphezulu ze-hydrogen ezisebenzayo ukwenza i-polymer.I-DDI ingasetshenziswa ku-rocket propellant eqinile, ukuqedela indwangu, iphepha, isikhumba kanye nendwangu yokuxosha indwangu, ukwelashwa kokulondoloza ukhuni, ukubumba kukagesi nokulungiswa kwezakhiwo ezikhethekile ze-polyurethane (urea) elastomers, i-adhesive kanye ne-sealant, njll.

Embonini Yendwangu, i-DDI ikhombisa ithuba elihle lokusebenzisa izinto ezixosha amanzi nezithambisa izindwangu.Ayizweli kakhulu emanzini kunama-isocyanate anephunga elimnandi futhi ingasetshenziswa ukulungisa ama-emulsion anamanzi azinzile.

Ukusetshenziswa kwe-0.125% DDI kunikeza indwangu ukuthamba okuhlala isikhathi eside;Izindwangu eziphathwe ngezithambisa ze-cationic ezingabekezeleleki zinokuguquguquka okufanayo ngemva kokugeza okungu-26.Indwangu exosha amanzi esebenzisa i-1% DDI inomphumela ofanayo noma ongcono wokuxosha amanzi njenge-fat pyridine water repellent (ukuhlolwa kwe-AATCC).

I-DDI ingathuthukisa umphumela wokuxosha amanzi kanye nokuxosha uwoyela ezindwangu ezine-fluorinated.Uma isetshenziswa ihlangene, i-DDI ingathuthukisa kakhulu izici zezindwangu ezixosha amanzi kanye nezixosha uwoyela.

Kokubili ukuhlolwa kwelabhorethri kanye nenkundla kubonise ukuthi i-DDI inokumelana kangcono nokuwashwa nokuhlanza okomile kunezithasiselo ze-fluoride noma zendwangu njengama-antistatic agents.

I-DDI, elungiswe ngama-dimer fatty acids, iyinhlobonhlobo ye-isocyanate evamile eluhlaza, evuselelwa nge-bio.Uma kuqhathaniswa ne-universal isocyanate TDI, MDI, HDI ne-IPDI, i-DDI ayinabo ubuthi futhi ayikhuthazi.Ngokuthandwa kwezinto zokusetshenziswa kwe-dimeric acid e-China kanye nokunaka kwabantu okwandayo emnothweni ophansi wekhabhoni evikela imvelo kanye nentuthuko esimeme, ukubaluleka kokusebenzisa izinto zokusetshenziswa ezivuselelekayo ze-bio-renewable ukulungisa i-DDI kuye kwavela kancane kancane, okunokubaluleka okubalulekile okusebenzayo ekukhuthazeni ukuthuthukiswa imboni ye-polyurethane.
