Pentamethyldiethylenetriamine (pmdeta)

methyl ise ethyleneamine atọ bụ ihe na-emeghachi omume nke ukwuu maka mmeghachi omume polyurethane.Ọ na-ebutekarị mmeghachi omume ụfụfụ, a na-ejikwa ya mee ka ọ dị mma n'ozuzu ụfụfụ na mmeghachi omume gel.A na-eji ya eme ihe n'ụdị ọ bụla nke ụfụfụ siri ike nke polyurethane, gụnyere polyisocyanurate efere siri ike ụfụfụ.N'ihi mmetụta ọfụfụ siri ike ya, ọ nwere ike ime ka ọkpụkpụ nke ụfụfụ dịkwuo mma, n'ihi ya, ọ na-eme ka usoro mmepụta ahụ dịkwuo mma ma na-eme ka olu nke mmepụta dịkwuo mma.Ọ na-ekerịtakarị DMCHA na ihe ndị ọzọ.A na-eji methyl abụọ ethyleneamine atọ amine naanị mee ihe dị ka ihe na-eme ka usoro ụfụfụ polyurethane dị, ma nwekwara ike ịkekọrịta ya na ihe ndị ọzọ.0-2.0 akụkụ kwa 100 akụkụ nke polyol.
Na mgbakwunye na nhazi ụfụfụ siri ike, a pụkwara iji methyl abụọ ethyleneamine atọ mee ihe na mmepụta nke polyether polyurethane soft foam na ịkpụzi ụfụfụ.Dịka ọmụmaatụ, 70% nke pentamethylenediethylenetriamine bụ nke a na-ejikarị eme ihe n'ichepụta ngwaahịa ụfụfụ dị nro.Ihe na-akpali akpali nwere ọrụ dị elu, ọsọ ụfụfụ ngwa ngwa, ike siri ike na nnukwu ibu.Na ụfụfụ dị nro, 0.1-0.5 phr nke ihe na-eme ka ọ bụrụ 100 phr nke polyether nwere ike nweta mmetụta dị mma.Enwere ike iji ya dị ka ihe inyeaka maka ụfụfụ siri ike.
Nke ise methyl abụọ ethyleneamine atọ amine quaternary ammonium nnu bụ ihe na-egbu oge maka ụfụfụ dị nro, nke a na-eji mee ka oge ụfụfụ dị ogologo.Ọ dị mma maka ngwaahịa ụfụfụ nwere usoro mgbagwoju anya na ụdị igbe, ma na-eme ka nhazi nke ụfụfụ dịkwuo mma ma na-eme ka ọkpụkpụ dị mma.Usoro nke usoro onunu ogwu ya di oke oke, na mgbanwe nke onunu ogwu enweghi mmetụta doro anya na oge ncha;Ma ịba ụba nke usoro onunu ogwu nwere ike ibelata oge ịrị elu nke ụfụfụ ma belata oge ọgwụgwọ.
