DDI (Dimeryl Diisocyanate)
| Zogulitsa: | Dimeryl diisocyanate(DDI 1410) | Nambala ya CAS: | 68239-06-5 |
| Molecular formula: | Chithunzi cha C36H66N2O2 | EINECS: | 269-419-6 |
Kusamala Kagwiridwe ndi Kasungidwe: KHALANI NDI NTCHITO CHOTSIRIDWA MWAVUTA POSAGWIRITSA NTCHITO.SOLOKA MALO Owuma.
Dimeryl diisocyanate (DDI) ndi aliphatic (dimer fatty acid diisocyanate) yapadera ya diisocyanate yomwe ingagwiritsidwe ntchito ndi mankhwala omwe ali ndi haidrojeni yogwira ntchito pokonzekera zotumphukira zotsika kwambiri zama cell kapena ma polima apadera.
DDI ndi unyolo wautali wokhala ndi unyolo waukulu wamafuta a dimeric okhala ndi ma atomu a kaboni 36.Mapangidwe a msanawa amapatsa DDI kusinthasintha kwapamwamba, kukana madzi komanso kawopsedwe kakang'ono kuposa ma isocyanate ena aliphatic.
DDI ndimadzimadzi ocheperako omwe amasungunuka mosavuta muzosungunulira za polar kapena nonpolar.

Zolemba
1) deta yonse yaukadaulo yomwe yawonetsedwa pamwambapa ndi yanu.
2) Mafotokozedwe ena ndi olandiridwa kuti mupitirize kukambirana.
DDI angagwiritsidwe ntchito olimba rocket propellant, nsalu yomaliza, mapepala, zikopa ndi nsalu othamangitsa, nkhuni zosungira mankhwala, potting magetsi ndi kukonzekera katundu wapadera wa polyurethane (urea) elastomers, zomatira ndi sealant, etc.
DDI ili ndi kawopsedwe wochepa, wopanda chikasu, amasungunuka muzosungunulira zambiri za organic, tcheru pamadzi otsika komanso kukhuthala kochepa.
M'makampani a Nsalu, DDI ikuwonetsa mwayi wogwiritsa ntchito bwino pakuchotsa madzi komanso kufewetsa nsalu.Simamva bwino kwambiri ndi madzi kuposa ma isocyanates onunkhira ndipo imatha kugwiritsidwa ntchito popanga ma emulsions okhazikika amadzimadzi.DDI ikhoza kupititsa patsogolo mphamvu ya madzi oletsa madzi ndi mafuta opangira nsalu za fluorinated.Akagwiritsidwa ntchito pamodzi, DDI ikhoza kupititsa patsogolo kwambiri nsalu zopanda madzi komanso mafuta.
DDI, yokonzedwa kuchokera ku dimer fatty acids, ndi mtundu wobiriwira, wosasinthika wa isocyanate.Poyerekeza ndi Universal isocyanate TDI, MDI, HDI ndi IPDI, DDI ndi yopanda poizoni komanso yosalimbikitsa.
Kugwira: Pewani kukhudza madzi.Onetsetsani kuti pali mpweya wabwino kuntchito.
Kusungirako: Sungani muzitsulo zotsekedwa mwamphamvu, zoziziritsa ndi zouma.
Zambiri zamayendedwe: osayendetsedwa ngati chinthu chowopsa.
