Desmodur RE, nke a makwaara dị ka CAS 2422-91-5, bụ ihe dị iche iche na-ejikarị eme ihe. N'ihi ọmarịcha arụmọrụ ya na uru ya, ejirila ya mee ihe na ụlọ ọrụ dị iche iche. N'isiokwu a, anyị na-enyocha iji Desmodur ma chọpụta ihe kpatara ya ji ewu ewu na ndị na-emepụta ihe.
Desmodur RE bụ nke ezinụlọ aromatic diisocyanates, ogige ndị a na-ejikarị eme ihe na-emepụta ihe mkpuchi polyurethane, adhesives na elastomers. Ọ bụ mmiri mmiri na-acha odo odo ruo amber nke nwere ngwakọta nke isomers nwere usoro kemịkal yiri ya. Isi ihe dị na Desmodur RE bụ toluene diisocyanate (TDI), nke a na-ejikarị eme ihe na-emepụta ụfụfụ polyurethane.
Otu n'ime isi ojiji nkeDesmodur REbụ n'ichepụta ihe mkpuchi nke polyurethane. Ihe mkpuchi polyurethane na-enye nchebe dị mma megide corrosion, ihu igwe na abrasion. A maara ha maka ịdịte aka ha dị elu na arụmọrụ dị mma na gburugburu ebe siri ike. Desmodur RE bụ akụkụ dị mkpa na usoro mkpuchi ndị a, na-enye ha ụbara ike, nrapanye na nguzogide kemịkalụ.
Ngwa ọzọ dị mkpa nke Desmodur RE bụ mmepụta nke adhesives polyurethane. A na-eji adhesives polyurethane eme ihe na ụlọ ọrụ ụgbọ ala, ihe owuwu na arịa ụlọ n'ihi ike njikọ ha dị elu na ntụgharị. Desmodur RE na-akwalite ike nkekọ nke polyurethane adhesives, na-enye ha ohere ịrapagidesi ike na ihe dị iche iche dị ka ígwè, plastik na osisi. Nke a na-eme ka ha dị mma maka lamination, bonding na sealing ngwa.
A na-ejikwa Desmodur RE na mmepụta nke polyurethane elastomers. Polyurethane elastomers na-egosiputa ihe eji arụ ọrụ dị mma dị ka oke ngbanwe, nguzogide akwa na nguzogide abrasion. A na-eji ha na ụlọ ọrụ dịka akpụkpọ ụkwụ, ụgbọ ala na mmepụta ihe. Desmodur RE na-arụ ọrụ dị mkpa na njikọ nke elastomers ndị a, na-enye ha ike ike dị mma na ihe elongation.
Ọzọkwa,Desmodur REmara maka ngwa ngwa ọgwụgwọ Njirimara. Nke a pụtara na ọ nwere ike ịgafe ngwa ngwa na polyols iji mepụta netwọk polyurethane siri ike. Ngwọta ngwa ngwa bụ ihe a na-achọsi ike na ụlọ ọrụ na-achọ oge ntụgharị ngwa ngwa, dị ka ụlọ ọrụ ụgbọ ala ma ọ bụ ihe owuwu. Na mgbakwunye, Desmodur RE nwere ezigbo ndakọrịta na ọtụtụ polyols, na-enyere ndị na-emepụta ihe aka ịhazi njirimara nke ngwaahịa ha na ihe achọrọ.
N'ikpeazụ, Desmodur RE (CAS 2422-91-5) bụ ihe a na-ejikarị eme ihe na ngwa ngwa na ụlọ ọrụ dị ka mkpuchi, adhesives na elastomers. Ngwongwo ya pụrụ iche, gụnyere ike siri ike, nrapanye na ọgwụgwọ ngwa ngwa, na-eme ka ọ bụrụ nhọrọ a ma ama n'etiti ndị nrụpụta. Ma inye nchebe corrosion site na mkpuchi polyurethane, nweta njikọ siri ike na adhesives, ma ọ bụ na-eme ka ihe ndị na-emepụta ihe nke elastomers dịkwuo mma, Desmodur RE egosila na ọ bụ ihe dị mkpa na mmepụta ihe dị elu.
