Zoo Dimeryl Diisocyanate DDI CAS NO. 68239-06-5
TSIS MUAJ yog ib qho tshwj xeeb aliphatic diisocyanate uas tuaj yeem siv los npaj cov polymers nrog cov tebchaw uas muaj cov nquag hydrogen. Nws yog cov saw ntev ntev nrog 36-carbon dimer fatty acid qaum. Lub ntsiab saw qauv muabTSIS MUAJsuperior yooj, dej tsis kam thiab tsis muaj tshuaj lom rau lwm yam aliphatic isocyanates.TSIS MUAJ yog cov kua viscosity tsawg uas yooj yim soluble nyob rau hauv feem ntau polar los yog non-polar solvents. Vim nws yog aliphatic isocyanate, muaj cov yam ntxwv ntawm tsis daj. Nws muaj ntau yam zoo ntawm cov tshuaj toxicity tsawg, yooj yim rau siv, soluble nyob rau hauv feem ntau cov kuab tshuaj, tswj lub sij hawm tshuaj tiv thaiv thiab dej rhiab heev. Nws yog ib hom ntsuab biorenewable tshwj xeeb isocyanate ntau yam, uas tuaj yeem siv dav hauv cov ntaub ntawv xov, elastomers, adhesives thiab sealants, coatings, inks thiab lwm yam tub rog thiab pej xeem teb.
1. Npuag: peb DDI nrog dej yooj yim los 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 nrog preformance ntawm tsis-daj, zoo heev resilience, thiab extensile, siab nruj, tsis tshua muaj dej sensible, thiab zoo anti-abrasivenesss, anti-tshuaj hnyav, thiab anti-tsawg kub.
3. Teb nrogHTPBkom ua tau zoo tshaj plaws thiab muaj kev sib haum xeeb, cov khoom tsim PU tuaj yeem ua qhov txawv txav tsis zoo, tsis xav tau tus neeg sawv cev yas.
4. Txheej. DDI polyurea txheej nrog zoo tensile zog thiab huab cua pov thawj, uas yog yooj yim adhered rau hlau thiab ntoo yam tsis muaj puas.
