I-Dimeryl Diisocyanate DDI CAS NO. esezingeni eliphezulu 68239-06-5
CHA iyi-diisocyanate eyingqayizivele ye-aliphatic engasetshenziswa ukulungiselela ama-polymer anamakhemikhali aqukethe i-hydrogen esebenzayo. Iyinhlanganisela yeketanga elide enomgogodla we-36-carbon dimer fatty acid. Isakhiwo seketanga eliyinhloko sinikeza CHA ukuguquguquka okuphezulu, ukumelana namanzi kanye nobuthi obuphansi kwezinye i-aliphatic isocyanates. CHA luwuketshezi olune-viscosity ephansi oluncibilika kalula ezinyibilikeni eziningi ze-polar noma ezingezona ze-polar. Ngenxa yokuthi luyi-aliphatic isocyanate, lunezici zokungaphuzi. Lunezinzuzo eziningi zobuthi obuphansi, kulula ukuyisebenzisa, luncibilika ezinyibilikeni eziningi, isikhathi sokusabela esilawulekayo kanye nokuzwela kwamanzi okuphansi. Luhlobo olujwayelekile lwe-isocyanate ekhethekile eluhlaza okotshani, olungasetshenziswa kabanzi ekuqedeni indwangu, ama-elastomer, ama-adhesive nama-sealant, izimbozo, uyinki kanye neminye imikhakha yezempi neyezomphakathi.
1. Indwangu: i-DDI yethu enamanzi kalula ukuze ibe yi-emulsion yamanzi, okwenza indwangu ibe bushelelezi, ithambile, futhi ingangeni manzi.
2. I-PU resin kanye ne-Polyurea resin, kusetshenziswa i-DDI kungaba nokwakheka okungephuzi, ukuqina okuhle kakhulu, kanye nokwelulwa, ukuqina okuphezulu, ukuzwela kwamanzi aphansi, kanye nokulwa nokuguguleka okungcono, i-anti-chemical solvent, kanye nokushisa okuphansi.
3. Phendula nge I-HTTPB Ukuze kube ukuhambisana okuhle kakhulu kanye nokusebenza kahle, i-PU ekhiqizwayo ingaba lukhuni kakhulu, ayidingi i-ejenti yepulasitiki.
4. Ukugqoka. Ukugqoka kwe-DDI polyurea okunamandla amahle kakhulu okubamba futhi okumelana nesimo sezulu, okunamathela kalula ensimbini nasezinkunini ngaphandle kokuphuka.
