Melamine formaldehyde resin bụ ụdị melamine resin ọhụrụ, nke e ji melamine na formaldehyde mee site na mmeghachi omume polycondensation. Melamine formaldehyde resin nwere ihe anụ ahụ na nke mekaniki dị mma, iguzogide kemịkalụ dị elu, iguzogide okpomọkụ na iguzogide mmiri. Mmiri na iguzogide mmiri na ịdịte aka nke ngwaahịa ya dị mma karịa nke urea-formaldehyde resin, yabụ a na-eji ya eme ihe nke ukwuu n'ịmepụta ngwá ụlọ na ịchọ mma ụlọ. N'ihi ezigbo enyi gburugburu ebe obibi ya, a na-ewere melamine formaldehyde resin dị ka ngwaahịa zuru oke iji dochie urea-formaldehyde resin.
N'ime afọ ndị na-adịbeghị anya, melamine formaldehyde resin aghọwo ezigbo ụdị ọhụrụ nke nrapado maka nhazi osisi n'ihi nnukwu okpomọkụ na-eguzogide ya, mmiri na-eguzogide mmiri na mmiri ọgwụ.
E jiri ya tụnyere urea-formaldehyde resin, melamine-formaldehyde resin nwere uru ndị a: ọdịnaya formaldehyde dị ala, kwekọrọ na ihe ndị a chọrọ maka nchebe gburugburu ebe obibi, usoro mmepụta dị mfe, àgwà ngwaahịa dị mma, arụmọrụ kwụsiri ike, dị mfe nhazi na ịkpụzi.
E nwere ụzọ abụọ isi synthesizing maka melamine formaldehyde resin: otu bụ usoro kpọmkwem na nke ọzọ bụ usoro na-apụtaghị ìhè. Usoro kpọmkwem bụ ijikọta melamine na formaldehyde, na-ekpo ọkụ na ihe dịka 70 ° C, wee na-achịkwa okpomọkụ dị n'etiti 80 ° C ~ 90 ° C site n'ịgbakwunye ihe, na-ekpo ọkụ, na-akpali akpali, wdg, na-emeghachi omume maka 3 ~ 4h, mgbe ahụ, a ga-enweta resin melamine formaldehyde. N'ime usoro a, a na-eji nitrogen echebe formaldehyde ka ọ ghara ịhapụ ya. Ụzọ na-apụtaghị ìhè bụ ịgwakọta melamine na formaldehyde ma tinye ha na reactor maka mmeghachi omume. Ebe ọ bụ na melamine na formaldehyde bụ ihe ndị na-adịghị ike alkaline, H + na OH-emepụta n'oge mmeghachi omume nwere ike imeghachi omume na CO2, H2O na gas ndị ọzọ dị na ikuku iji mepụta ihe ndị na-esi ísì ụtọ, nke dịpụrụ adịpụ site na ikuku site na ịpụ na kettle, na melamine-formaldehyde resin synthesized, nke a pụrụ inweta site na distillation.
Njirimara njikọ na gluing nke melamine-formaldehyde resins na-abawanye site na mmụba nke ọdịnaya melamine na resin melamine-formaldehyde. Otú ọ dị, njikọ na gluing Njirimara nke melamine formaldehyde resin na-ebelata na okpomọkụ na-arịwanye elu, ebe njigide ya na-abawanye na okpomọkụ na-abawanye. Mgbe okpomọkụ na-ebili ruo n'ókè ụfọdụ, viscosity na-ebelata ruo otu uru wee malite ịmalite ọzọ. N'ime mpaghara ụfọdụ, viscosity nke melamine formaldehyde resin na-ebelata site na mmụba nke ọdịnaya melamine. E jiri ya tụnyere urea-formaldehyde resin, nguzogide okpomọkụ ya, nguzogide mmiri na nguzogide kemịkal dị mma karịa nke resin urea-formaldehyde.
A na-ejikarị resin Melamine formaldehyde eme ihe n'ịhazi osisi maka plywood, joinery, plywood na ihe ndị ọzọ, a pụkwara iji ya mee ihe dị ka ihe ndabere nke veneer film film veneer artificial board. Na mgbakwunye, enwere ike iji ya maka ụdị boards niile mmadụ mere nke e ji akwụkwọ na particles chọọ mma, fiberboards ọkara njupụta, strand boards ndị e ji akwụkwọ film drain kpụọ mma. N'ihe gbasara ịchọ mma ụlọ, melamine formaldehyde resin nwere ezigbo iguzogide mmiri na ogologo oge, enwere ike iji ya mee ihe n'ụdị ihe ịchọ mma ime ụlọ na ihe ịchọ mma n'èzí. Enwere ike iji resin Melamine formaldehyde na-emepụta plywood na-eguzogide okpomọkụ, akwụkwọ melamine (a na-akpọ akwụkwọ melamine) na akwụkwọ melamine drain. Enwere ike iji ya dị ka ihe ndabere maka board artificial film drained, yana dị ka ihe ịchọ mma ime ụlọ dị ka board particle, medium density fiberboard na blockboard nke e ji akwụkwọ drain kpụọ mma.
Enwere ike iji resin melamine formaldehyde rụpụta arịa ụlọ na ngwaahịa osisi, yana iwu ihe eji achọ mma dị ka veneer, agba, plywood, bọọdụ mgbochi, yana bọọdụ arụrụ arụ. Enwere ike iji resin melamine formaldehyde dị ka ihe eji ewu ụlọ na ihe ịchọ mma ime ụlọ, a pụkwara iji ya mee ihe dị ka ihe nkwakọ ngwaahịa nri. N'ihi na melamine formaldehyde resin nwere ọmarịcha anụ ahụ na arụ ọrụ yana nguzogide kemịkal, a na-eji ya eme ihe n'ịrụ plywood na blockboard. Uru ndị bụ isi nke melamine-formaldehyde resin bụ ezigbo anụ ahụ na akụrụngwa, ezigbo okpomọkụ na nguzogide mmiri, a na-ejikarị ya eme ihe n'ịmepụta eriri njupụta nke ọkara na particleboard.
