Umehluko Phakathi kweMelamine neMelamine Resin
1. Isakhiwo Samakhemikhali Nokwakheka Kwawo
- I-Melamine
- Ifomula yamakhemikhali: C3H6N6C3H6N6
- Inhlanganisela encane ephilayo enendandatho ye-triazine kanye nama-amino amathathu (−NH2−NH2) amaqembu.
- Impuphu emhlophe ekristalu, encibilika kancane emanzini.
- I-Melamine Resin (i-Melamine-Formaldehyde Resin, i-MF Resin)
- I-polymer ye-thermosetting eyakhiwe yi-condensation reaction ye-melamine ne-formaldehyde.
- Ayikho ifomula yamakhemikhali engaguquki (isakhiwo senethiwekhi ye-3D esixhumene).
2. Ukwenziwa
- I-Melamineikhiqizwa ezimbonini nge-urea ngaphansi kokushisa okuphezulu kanye nengcindezi.
- I-Melamine ResinKwenziwa ngokusabela i-melamine ne-formaldehyde (enezikhuthazi ezifana ne-asidi noma isisekelo).
3. Izakhiwo Eziyinhloko
| Impahla | I-Melamine | I-Melamine Resin |
| Ukuncibilika | Kuncibilika kancane emanzini | Akuncibiliki ngemva kokupholisa |
| Ukuzinza Kokushisa | Iyabola ku-~350°C | Ayishisi (kufika ku-~200°C) |
| Amandla Okusebenza | Amakristalu athambile | Kuqinile, akuklwebheki |
| Ubuthi | Kunobuthi uma kudliwa (isib. ukulimala kwezinso) | Ayinabo ubuthi uma ilapheke ngokuphelele (kodwa i-formaldehyde esele ingaba yinto ekhathazayo) |
4. Izicelo
- I-Melamine
- Izinto zokusetshenziswa ze-melamine resin.
- I-retardant yomlilo (uma ihlanganiswa nama-phosphate).
- I-Melamine Resin
- Ama-Laminate: Ama-countertop, izindawo zefenisha (isib. i-Formica).
- Izitsha zokudla kwakusihlwa: Izitsha zokudla ze-Melamine (zilingisa i-porcelain kodwa zilula).
- Izinamathiseli Nokumboza: Iglue yokhuni engangeni manzi, izembozo zezimboni.
- Izindwangu Nephepha: Kuthuthukisa ukumelana nemibimbi kanye nomlilo.
5. Isifinyezo
| Isici | I-Melamine | I-Melamine Resin |
| Imvelo | I-molecule encane | I-Polymer (exhumene) |
| Ukuzinza | Iyancibilika, iyabola | I-Thermoset (ayincibiliki uma ilashwa) |
| Ukusetshenziswa | Isandulela samakhemikhali | Umkhiqizo wokugcina (ipulasitiki, izembozo) |
| Ukuphepha | Ubuthi ngamanani aphezulu | Kuphephile uma kuphulukiswe kahle |
I-Melamine resin iwuhlobo lwe-melamine olusetshenziswa kakhulu embonini, olunikeza ukuqina nokumelana nokushisa, kanti i-melamine emsulwa iyindlela yamakhemikhali enezicelo eziqondile ezilinganiselwe.
