I-Diisocyanate (DDI) yi-aliphatic diisocyanate eyodwa kunye ne-36 carbon atom dimer fatty acid backbone.Ulwakhiwo lunika i-DDI ukuguquguquka okungcono kunye nokubambelela kunezinye isocyanates aliphatic.I-DDI ineempawu zetyhefu ephantsi, akukho tyheli, inyibilika kwi-solvents ezininzi ze-organic, ubuthathaka bamanzi aphantsi kunye ne-viscosity ephantsi.I-DDI luhlobo lwemisebenzi emibini ye-Isocyanate, inokusebenza ngeekhompawundi zehydrogen ezimbini okanye ngaphezulu ezisebenzayo ukwenza ipolima.I-DDI ingasetyenziselwa i-rocket propellant eqinile, ukugqiba ilaphu, iphepha, isikhumba kunye ne-repellent yelaphu, unyango lokukhusela umthi, ukubumba kombane kunye nokulungiswa kweempawu ezikhethekileyo ze-polyurethane (urea) elastomers, i-adhesive kunye ne-sealant, njl.

Kushishino lweFabric, i-DDI ibonisa i-app egqwesileyo ye-prospect in the water-repent and softening properties to fabrics.Ayinabungozi kangako emanzini kune-isocyanates enevumba elimnandi kwaye ingasetyenziselwa ukulungisa i-emulsions enamanzi azinzileyo.

Ukusetyenziswa kwe-0.125% DDI kunika ilaphu ukuthamba okuhlala ixesha elide;Amalaphu aphathwe ngezinto ezithambileyo ze-cationic ezinokuguquguquka okufanayo emva kokuhlamba kwe-26.Ilaphu lokugxotha amanzi lisebenzisa i-1% DDI linesiphumo esifanayo okanye esingcono sokugxotha amanzi njenge-fat pyridine yokugxotha amanzi (uvavanyo lwe-AATCC).

I-DDI inokuphucula isiphumo sokugxotha amanzi kunye ne-oyile yokugxotha amalaphu e-fluorinated.Xa isetyenziswe ngokudibeneyo, i-DDI inokuphucula ngokubonakalayo iipropati zokugxotha amanzi kunye neoli ye-oyile yempahla.

Zombini iilabhoratri kunye novavanyo lwasendle lubonise ukuba i-DDI inokumelana ngcono nokuhlamba kunye nokucoca okomileyo kune-fluoride okanye izongezo zelaphu ezifana ne-antistatic agents.

I-DDI, elungiselelwe ukusuka kwi-dimer fatty acids, luhlobo oluqhelekileyo lwe-isocyanate eluhlaza, ehlaziyiweyo ye-bio.Xa kuthelekiswa ne-Universal isocyanate TDI, MDI, HDI kunye ne-IPDI, i-DDI ayinayo inetyhefu kwaye ayikhuthazi.Ngokuthandwa kwezixhobo ze-dimeric acid ekrwada eTshayina kunye nokunyuka kwabantu ingqalelo kwikhabhoni ephantsi yokhuselo lokusingqongileyo kunye nophuhliso oluzinzileyo, ukubaluleka kokusebenzisa izinto ezivuselelwayo ze-bio-renewable ukulungiselela i-DDI iye yavela ngokuthe ngcembe, enentsingiselo ebalulekileyo ebonakalayo ekukhuthazeni uphuhliso lwendalo. imboni yepolyurethane.
