Zoo Dimeryl Diisocyanate DDI CAS TSIS MUAJ. 68239-06-5
TSIS MUAJ yog ib qho tshwj xeeb aliphatic diisocyanate uas siv tau los npaj cov polymers nrog cov tshuaj uas muaj cov hydrogen nquag. Nws yog ib qho tshuaj ntev nrog 36-carbon dimer fatty acid backbone. Cov qauv tseem ceeb muab TSIS MUAJ kev ywj pheej zoo dua, kev tiv thaiv dej thiab tsis muaj tshuaj lom rau lwm cov aliphatic isocyanates. TSIS MUAJ yog cov kua viscosity qis uas yooj yim yaj hauv feem ntau cov kuab tshuaj polar lossis tsis-polar. Vim tias nws yog aliphatic isocyanate, muaj cov yam ntxwv ntawm tsis-daj. Nws muaj ntau qhov zoo ntawm kev lom tsawg, yooj yim siv, yaj hauv feem ntau cov kuab tshuaj, lub sijhawm tshuaj tiv thaiv tswj tau thiab dej tsis rhiab heev. Nws yog ib hom isocyanate tshwj xeeb biorenewable ntsuab, uas tuaj yeem siv dav hauv cov ntaub tiav, elastomers, adhesives thiab sealants, coatings, inks thiab lwm yam tub rog thiab pej xeem teb.
1. Npuag: peb DDI nrog dej yooj yim ua aqueous emulsion, uas ua rau cov ntaub du, gentile, thiab dej-pov thawj.
2. PU resin thiab Polyurea resin, siv DDI tuaj yeem ua tau zoo nrog kev ua tsis daj, muaj zog zoo heev, thiab extensile, siab rigid, dej tsawg sensible, thiab zoo dua anti-abrasivenesss, tshuaj lom neeg tiv thaiv, thiab tiv thaiv kub tsawg.
3. Teb nrog HTPB Yuav kom muaj kev sib raug zoo thiab kev ua haujlwm zoo heev, PU tsim tawm tuaj yeem ua tau zoo heev uas tsis muaj zog, tsis tas yuav muaj cov neeg sawv cev yas.
4. Txheej. DDI polyurea txheej nrog lub zog tensile zoo heev thiab tiv taus huab cua, uas yooj yim lo rau hlau thiab ntoo yam tsis muaj tawg.
