Dimeryl Diisocyanate DDI CAS NO. 68239-06-5
Mba bụ diisocyanate aliphatic pụrụ iche nke enwere ike iji kwadebe polymers nwere ogige nwere hydrogen na-arụ ọrụ. Ọ bụ ngwakọta nwere ogologo agbụ nke nwere azụ azụ abụba 36-carbon dimer fatty acid. Isi yinye Ọdịdị na-enyeMbamgbanwe dị elu, nguzogide mmiri na obere nsí na ndị ọzọ aliphatic isocyanates.Mba bụ obere viscosity mmiri mmiri na-adị mfe soluble na ọtụtụ pola ma ọ bụ ndị na-abụghị pola solvents. N'ihi na ọ bụ aliphatic isocyanate, nwere àgwà nke na-abụghị odo. Ọ nwere ọtụtụ uru nke toxicity dị ala, dị mfe iji, soluble na ọtụtụ ihe mgbaze, oge mmeghachi omume na-achịkwa na obere mmetụta mmiri. Ọ bụ ihe na-ahụkarị green biorenewable pụrụ iche isocyanate, nke nwere ike n'ọtụtụ ebe na-eji na-emecha ákwà, elastomers, adhesives na sealants, coatings, ink na ndị ọzọ agha na obodo ubi.
1. Fabric: DDI anyị na mmiri dị mfe ka ọ bụrụ emulsion aqueous, nke mere ka ákwà ahụ dị nro, nke na-adịghị mma, na mmiri na-adịghị.
2. PU resin na Polyurea resin, iji DDI nwere ike ịbụ na preformance nke na-abụghị yellowing, magburu onwe resilience, na extensile, elu isiike, ala mmiri ezi uche, na mma mgbochi abrasiveness, mgbochi chemical mgbaze , na mgbochi ala okpomọkụ.
3. Meghachi omume naHTPBIji bụrụ ezigbo ndakọrịta na mmeghachi omume, PU emepụtara nwere ike bụrụ ihe siri ike dị ala, ọ nweghị onye nnọchi rọba chọrọ.
4. mkpuchi. DDI polyurea mkpuchi na magburu onwe tensile ike na ihu igwe na-egosi, nke na-adị mfe na-arapara na ígwè na osisi na-enweghị mgbaji.
