Umehluko Phakathi kweMelamine neMelamine Resin
1. Isakhiwo Samakhemikhali Nokwakheka
- I-Melamine
- Ifomula yamakhemikhali: C3H6N6C3H6N6
- Inhlanganisela encane yemvelo enendandatho ye-triazine nama-amino amathathu (-NH2−NH2) amaqembu.
- I-crystalline powder emhlophe, inyibilika kancane emanzini.
- I-Melamine Resin (i-Melamine-Formaldehyde Resin, i-MF Resin)
- I-polymer ye-thermosetting eyakhiwe ukusabela kokujiya kwe-melamine ne-formaldehyde.
- Alikho ifomula yamakhemikhali engashintshi (isakhiwo senethiwekhi ye-3D exhunywe ngokuphambanayo).
2. Ukuhlanganisa
- I-Melamineikhiqizwa ngokwezimboni kusuka ku-urea ngaphansi kokushisa okuphezulu nokucindezela.
- I-Melamine Resinihlanganiswa ngokuphendula i-melamine ne-formaldehyde (ene-catalysts njenge-asidi noma isisekelo).
3. Izakhiwo Ezibalulekile
| Impahla | I-Melamine | I-Melamine Resin |
| Ukuncibilika | Incibilika kancane emanzini | Ayincibiliki ngemva kokwelashwa |
| Ukuzinza Okushisayo | Ibola ku-~350°C | Ikwazi ukumelana nokushisa (kufika ku-200°C) |
| Amandla Emishini | Amakristalu amancane | Iqinile, imelana nokuklwebheka |
| Ubuthi | Kunobuthi uma kudliwe (isb, ukulimala kwezinso) | Ayinabo ubuthi lapho yelashwe ngokugcwele (kodwa i-formaldehyde esele ingase ibe ukukhathazeka) |
4. Izicelo
- I-Melamine
- Impahla eluhlaza ye-melamine resin.
- I-flame retardant (uma ihlanganiswe nama-phosphates).
- I-Melamine Resin
- Ama-laminates: Izinto zokubala, izindawo zefenisha (isb, iFormica).
- I-Dinnerware: I-Melamine tableware (ilingisa i-porcelain kodwa engasindi).
- Ama-Adhesives & Coatings: Iglue yokhuni engavimbeli amanzi, izimbotshana zezimboni.
- Izindwangu & Iphepha: Ithuthukisa ukumelana nokushwabana nelangabi.
5. Isifinyezo
| Isici | I-Melamine | I-Melamine Resin |
| Imvelo | I-molecule encane | I-Polymer (exhunywe ngokuphambanayo) |
| Ukuzinza | Incibilika, iyabola | I-Thermoset (engancibiliki lapho yelashiwe) |
| Isebenzisa | Isandulela samakhemikhali | Umkhiqizo wokugcina (ipulasitiki, okokunamathela) |
| Ukuphepha | Ubuthi ngemithamo ephezulu | Iphephile uma yelashwe kahle |
I-melamine resin iwuhlobo lwe-melamine oluyi-polymerized, oluwusizo ezimbonini, olunikeza ukuqina nokumelana nokushisa, kuyilapho i-melamine ehlanzekile iyikhemikhali emaphakathi futhi isebenza ngokuqondile elinganiselwe.
