DDI (Dimeryl Diisocyanate)
| Chigadzirwa: | Dimeryl diisocyanate(DDI 1410) | Nhamba yeCAS: | 68239-06-5 |
| Molecular formula: | C36H66N2O2 | EINECS: | 269-419-6 |
Kubata uye Chengetedza Chengetedzo: Chengeta CONTAINER YAKnyatsovharwa PAUSINGASHANDISI.STORI PANZVIMBO YAKAoma.
Dimeryl diisocyanate (DDI) yakasarudzika aliphatic (dimer fatty acid diisocyanate) diisocyanate inogona kushandiswa nemakomponi ane inoshanda hydrogen kugadzirira yakaderera mamorekuru uremu kubva kana akakosha mapolymer.
DDI iketani refu ine cheni huru ye dimeric fatty acids ine 36 carbon atomu.Ichi chimiro chemusana chinopa DDI yepamusoro kushanduka, kuramba kwemvura uye kuderera kwehuturu pamusoro pemamwe aliphatic isocyanates.
DDI imvura yakaderera ye viscosity inonyungudika zviri nyore muzhinji polar kana nonpolar solvents.

Notes
1) data yese yehunyanzvi inoratidzwa pamusoro ndeye yako referensi.
2) kumwe kutsanangurwa kunogamuchirwa kune imwe hurukuro.
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.
DDI ine zvimiro zvechepfu yakaderera, isina yero, inonyungudika mune yakawanda organic solvents, yakaderera mvura inonzwa uye yakaderera viscosity.
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.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.
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.
Kubata: Dzivisa kubata nemvura.Ita shuwa kuti pane mhepo yakanaka panzvimbo yebasa.
Kuchengetedza: Chengetedza mumidziyo yakavharwa zvakasimba, inotonhorera uye yakaoma.
Ruzivo rwezvekufambisa: kwete kudzorwa sechinhu chine njodzi.
