DDI (Dimeryl Diisocyanate)

Mankhwala: Dimeryl diisocyanateAlirezatalischioriginal CAS Ayi. 68239-06-5
Njira yamagulu: C36H66N2O2 EINECS: 269-419-6

Kusamala ndi Kusamala: SUNGANI CHITSITSI CHIMAKHALA CHOTSEKA PAMENE MUNGAGWIRITSE NTCHITO. SUNGANI MALO OYERA.

Dimeryl diisocyanate (DDI) ndi aliphatic yapadera (dimer fatty acid diisocyanate) diisocyanate yomwe ingagwiritsidwe ntchito ndi mankhwala omwe ali ndi hydrogen yogwira kukonzekera zotengera zochepa zama molekyulu kapena ma polima apadera.
DDI ndi chingwe chotalika chomwe chimakhala ndi unyolo waukulu wamafuta amadzimadzi okhala ndi maatomu a kaboni 36. Kapangidwe kameneka kamene kamapangitsa DDI kusinthasintha kwambiri, kukana kwamadzi komanso kawopsedwe kabwino kuposa ma isocyanate ena a aliphatic.
DDI ndimadzimadzi otsika kwambiri omwe amatha kusungunuka mosavuta mumalo osungunulira kwambiri polar kapena nonpolar.

Zolemba

1) zonse zamaluso zomwe zatchulidwa pamwambapa ndizoyenera.
2) malingaliro ena ndiolandilidwa kuti mukambirane.
DDI itha kugwiritsidwa ntchito popanga miyala yolimba, kumaliza nsalu, mapepala, zikopa ndi zotchinga nsalu, mankhwala osungira nkhuni, kuphika kwamagetsi ndikukonzekera zida zapadera za polyurethane (urea) elastomers, zomatira ndi sealant, ndi zina zambiri.
DDI ili ndi poyizoni wochepa, yopanda chikasu, imasungunuka m'masungunulo ambiri am'madzi, madzi otsika kwambiri komanso mamasukidwe akayendedwe.
M'makampani Opangira nsalu, DDI ikuwonetsa chiyembekezo chabwino chogwiritsa ntchito m'malo othamangitsa madzi ndikuchepetsa nsalu. Imakhala yosazindikira madzi kuposa isocyanates onunkhira ndipo itha kugwiritsidwa ntchito kukonzekera ma emulsion okhazikika amadzimadzi. DDI itha kusintha mphamvu ya madzi othamangitsira madzi komanso mafuta othamangitsira nsalu. Pogwiritsidwa ntchito limodzi, DDI imatha kusintha kwambiri nsalu zotetezera madzi ndi mafuta.
DDI, yokonzedwa kuchokera ku mafuta ochepa, ndi mtundu wobiriwira wosakanikirana ndi isocyanate. Poyerekeza ndi chilengedwe chonse cha TDI, MDI, HDI ndi IPDI, DDI siyopanda poizoni komanso yosalimbikitsa.
Kugwira: Pewani kukhudzana ndi madzi. Onetsetsani kuti pali mpweya wabwino kuntchito.
Yosungirako: Sungani m'makontena otsekedwa kwambiri, ozizira komanso owuma.
Zambiri zamayendedwe: sizoyendetsedwa ngati zoopsa.
