Diisocyanate (DDI) yakasarudzika aliphatic diisocyanate ine 36 kabhoni atomu dimer fatty acid musana.Chimiro chinopa DDI zvirinani kuchinjika uye kunamatira kupfuura mamwe aliphatic isocyanates.DDI ine zvimiro zvechepfu yakaderera, isina yero, inonyungudika mune yakawanda organic solvents, yakaderera mvura inonzwa uye yakaderera viscosity.DDI imhando yemaitiro maviri eIsocyanate, inogona kushanda neaviri kana anopfuura anoshanda ehydrogen komisheni kugadzira polymer.DDI inogona kushandiswa mune yakasimba rocket propellant, machira ekupedzisa, pepa, dehwe uye jira repellent, huni inochengetedza kurapwa, magetsi potting uye kugadzirira kwakakosha zvivakwa zve polyurethane (urea) elastomers, adhesive uye sealant, nezvimwe.

Muindasitiri yeFabric, DDI inoratidza yakanakisa tarisiro yekushandisa mune inodzivirira mvura uye inopfavisa zvivakwa kumachira.Iyo hainyanyi kunzwa kumvura pane inonhuhwirira isocyanates uye inogona kushandiswa kugadzira yakagadzikana aqueous emulsions.

Kushandiswa kwe0.125% DDI kunopa jira kupfava kwakasimba;Micheka inobatwa nenondurable cationic softeners ine kushanduka kwakafanana mushure mekugeza makumi maviri nematanhatu.Mucheka unodzinga mvura uchishandisa 1% DDI ine zvakafanana kana zvirinani zvinodzingisa mvura semafuta epyridine anodzinga mvura (AATCC test).

DDI inogona kuvandudza mhedzisiro yemvura-inodzingisa uye mafuta-inodzinga machira efluorinated.Kana yakashandiswa pamwe chete, DDI inogona kuvandudza zvakanyanya mvura-inodzivirira uye inobvisa mafuta emidziyo yemachira.

Ose ari maviri ma laboratory uye emumunda ongororo dzakaratidza kuti DDI ine zvirinani kuramba kugeza uye kuchenesa yakaoma pane fluoride kana machira ekuwedzera senge antistatic agents.

DDI, yakagadzirwa kubva ku dimer fatty acids, ndeye yakasvibira, bio-inovandudzwa isocyanate akasiyana.Kana ichienzaniswa neyepasirese isocyanate TDI, MDI, HDI uye IPDI, DDI haina chepfu uye isingakurudzire.Nekuzivikanwa kwe dimeric acid raw materials muChina uye vanhu vari kuwedzera kutarisisa kune yakaderera kabhoni yekuchengetedzwa kwezvakatipoteredza hupfumi uye budiriro inoenderera, kukosha kwekushandisa bio-inovandudzwa mbishi kugadzirira DDI kwave kubuda zvishoma nezvishoma, izvo zvine zvakakosha zvakakosha zvakakosha mukusimudzira kusimudzira polyurethane industry.
