Umgangatho ophezulu weDimeryl Diisocyanate DDI CAS NO. 68239-06-5
HAYI yi-aliphatic diisocyanate ekhethekileyo enokusetyenziswa ukulungisa iipholima ezineekhompawundi eziqulethe i-hydrogen esebenzayo. Yikhompawundi emide ene-36-carbon dimer fatty acid backbone. Ulwakhiwo lwekhonkco oluphambili lunikaHAYIukuguquguquka okuphezulu, ukumelana kwamanzi kunye netyhefu ephantsi kwezinye i-aliphatic isocyanates.HAYI lulwelo olusezantsi lwe-viscosity olunyibilika ngokulula kuninzi lwezinyibilikisi ezimhlophe okanye ezingezizo ezipolar. Ngenxa yokuba i-aliphatic isocyanate, ineempawu zokungabi phuzi. Ineenzuzo ezininzi zetyhefu ephantsi, kulula ukuyisebenzisa, i-soluble kwi-solvents ezininzi, ixesha lokuphendula elilawulekayo kunye nobuthathaka bamanzi aphantsi. Luhlobo oluqhelekileyo lwe-isocyanate oluhlaza oluhlaziyiweyo oluqhelekileyo, olunokuthi lusetyenziswe ngokubanzi ekugqityweni kwelaphu, ii-elastomers, izinto zokuncamathelisa kunye nezitywina, ii-coatings, ii-inki kunye nezinye iindawo zasemkhosini kunye nezoluntu.
1. Ilaphu: i-DDI yethu ngamanzi ngokulula ukuba ibe yi-emulsion enamanzi, eyenza ilaphu libe ligudileyo, lithambile, kwaye lingenamanzi.
2. I-PU resin kunye ne-Polyurea resin, usebenzisa i-DDI ingaba ne-preformance ye-non-yellowing, i-resilience egqwesileyo, kunye ne-extensile, i-high rigid, i-low water enengqondo, kunye ne-anti-abrasiveness engcono, i-solvent anti-chemical, kunye ne-anti-low-low.
3. Phendula ngeHTPBukuze ibe nokuhambelana okugqwesileyo kunye nokusebenza kwakhona, iPU eveliswayo inokuba yinto enqabileyo ephantsi, akukho mfuneko ye-agent yeplastiki.
4. Ukwaleka. I-DDI i-polyurea yokwambathisa inamandla agqwesileyo okuqina kunye nobungqina bemozulu, ezibambelela ngokulula kwintsimbi kunye nomthi ngaphandle kokwaphuka.
