Ọdịiche Dị n'etiti Melamine na Melamine Resin
1. Chemical Structure & Nhazi
- Melamine
- Usoro ọgwụ: C3H6N6C3H6N6
- Obere ngwakọta organic nwere mgbanaka triazine na amino atọ (-NH2-NH2) otu.
- White crystalline ntụ ntụ, sobere ntakịrị na mmiri.
- Resin Melamine (Melamine-Formaldehyde Resin, MF Resin)
- Otu polymer nke na-ekpo ọkụ kpụrụ site na nzaghachi condensation nke melamine na formaldehyde.
- Enweghị usoro kemịkalụ edoziri (usoro netwọkụ 3D nwere njikọ gafere).
2. Synthesis
- MelamineA na-emepụta ụlọ ọrụ mmepụta ihe site na urea n'okpuru oke okpomọkụ na nrụgide.
- Melamine resinA na-emepụta melamine site na iji formaldehyde (ya na ihe na-eme ka acid ma ọ bụ isi).
3. Njirimara igodo
| Ngwongwo | Melamine | Melamine resin |
| Solubility | Na-agbaze ntakịrị na mmiri | Na-adịghị edozi ahụ mgbe a gwọchara ya |
| Thermal kwụsie ike | Na-emebi emebi na ~ 350 ° C | Okpomọkụ na-eguzogide (ruo ~200°C) |
| Mechanical Ike | Kristal na-agbaji agbaji | siri ike, na-eguzogide ọkọ |
| Nsi | Na-egbu egbu ma ọ bụrụ na etinyere ya (dịka ọmụmaatụ, mmebi akụrụ) | Na-adịghị egbu egbu mgbe a gwọrọ nke ọma (mana formaldehyde residual nwere ike ịbụ nchegbu) |
4. Ngwa
- Melamine
- Akụrụngwa maka melamine resin.
- Ọkụ na-egbochi ọkụ (mgbe ejikọtara ya na phosphates).
- Melamine resin
- Laminates: countertops, arịa ụlọ elu (dịka ọmụmaatụ, Formica).
- Nri nri abalị: Melamine tableware (na-eṅomi poselin ma dị arọ).
- Adhesives & mkpuchi: gluu osisi na-eguzogide mmiri, mkpuchi ụlọ ọrụ.
- Textiles & Akwụkwọ: Na-eme ka ọkpụkpụ na ọkụ na-eguzogide.
5. Nchịkọta
| Akụkụ | Melamine | Melamine resin |
| Ọdịdị | Obere molekul | Polymer (njikọ gafere) |
| Nkwụsi ike | Soluble, decomposes | Thermoset (na-adịghị edozi mgbe a gwọrọ) |
| Na-eji | Chemical precursor | Ngwaahịa ikpeazụ (plastik, mkpuchi) |
| Nchekwa | Nsi na oke doses | Ọ dị mma ma ọ bụrụ na a gwọọ ya nke ọma |
Melamine resin bụ polymerized, ụdị bara uru nke melamine, na-enye ogologo oge na nguzogide okpomọkụ, ebe melamine dị ọcha bụ etiti kemịkalụ nwere oke ngwa ngwa.
