Kusiyana pakati peMelamine neMelamine Resin
1. Chimiro cheKemikari & Kuumbwa
- Melamine
- Mushonga wekemikari: C3H6N6C3H6N6
- Mushonga mudiki organic komputa ine triazine ring uye matatu amino (-NH2-NH2) mapoka.
- White crystalline powder, inonyungudika zvishoma mumvura.
- Melamine Resin (Melamine-Formaldehyde Resin, MF Resin)
- Iyo thermosetting polymer inogadzirwa ne condensation reaction ye melamine uye formaldehyde.
- Hapana yakagadziriswa kemikari formula (yakabatana-yakabatana 3D network chimiro).
2. Synthesis
- Melamineinogadzirwa mumaindasitiri kubva kuurea pasi pekushisa kwakanyanya uye kumanikidzwa.
- Melamine Resininogadzirwa nekuita melamine ine formaldehyde (ine catalysts senge acid kana base).
3. Zvinhu Zvikuru
| Property | Melamine | Melamine Resin |
| Solubility | Zvishoma soluble mumvura | Insoluble mushure mekurapa |
| Thermal Kugadzikana | Inoora pa ~350°C | Inodzivirira kupisa (kusvika ~ 200°C) |
| Mechanical Simba | Brittle makristasi | Zvakaoma, zvinoramba kukwenya |
| Muchetura | Toxic kana ikadyiwa (semuenzaniso, kukuvara kweitsvo) | Isiri-chepfu kana yanyatsorapwa (asi yakasara formaldehyde inogona kunge iri kunetseka) |
4. Zvikumbiro
- Melamine
- Raw zvinhu zve melamine resin.
- Flame retardant (kana yasanganiswa nephosphates).
- Melamine Resin
- Laminates: Countertops, fenicha pamusoro (semuenzaniso, Formica).
- Dinnerware: Melamine tableware (inotevedzera porcelain asi isingaremi).
- Adhesives & Coatings: Mvura-inodzivirira huni glue, maindasitiri machira.
- Micheka & Pepa: Inovandudza kuunyana uye kuramba murazvo.
5. Pfupiso
| Aspect | Melamine | Melamine Resin |
| Nature | Diki molecule | Polymer (yakabatanidzwa) |
| Kugadzikana | Soluble, inoora | Thermoset (isina kunyungudika kana yarapwa) |
| Uses | Chemical precursor | Chigadzirwa chekupedzisira (mapurasitiki, machira) |
| Safety | Muchetura muhuwandu hwakawanda | Yakachengeteka kana yakanyatsorapwa |
Melamine resin ndiyo polymerized, inoshanda mumaindasitiri fomu ye melamine, inopa kusimba uye kudzivirira kupisa, nepo melamine yakachena ikemikari yepakati ine mashoma akananga maapplication.
