Farqiga u dhexeeya Melamine iyo Melamine Resin
1. Qaab-dhismeedka Kiimikada & Halabuurka
- Melamine
- Qaabka kiimikada: C3H6N6C3H6N6
- Iskudhis yar oo organic ah oo leh giraanta triazine iyo saddex amino (-NH2-NH2) kooxaha.
- Budada crystalline cad, wax yar ku milmay biyaha.
- Xabagta Melamine (Melamine-Formaldehyde Resin, MF Resin)
- polymer-ka heerkulbeeye ee uu sameeyay falcelinta uumiga ee melamine iyo formaldehyde.
- Ma jiro qaacido kiimiko oo go'an (qaab dhismeedka shabakad 3D ah oo isku xidhan).
2. Synthesis
- Melaminewaxa warshad ahaan laga soo saaraa HOL oo heerkul sarreeya iyo cadaadis saaran yahay.
- Melamine Resinwaxaa lagu farsameeyaa iyadoo la falcelinayo melamine leh formaldehyde (oo leh kiciyayaal sida acid ama saldhig).
3. Guryaha Furaha
| Hanti | Melamine | Melamine Resin |
| Solubility | Waxoogaa ku milmay biyaha | Aan la milmin ka dib marka la daweeyo |
| Deganaanshaha kulaylka | Wuxuu ku balaalaa ~350°C | Kulayl u adkaysta (ilaa ~200°C) |
| Xoogga Makaanikada | Kiristaalo jajaban | Adag, xoq u adkaysta |
| Sunta | Sun ah haddii la dhuuqo (tusaale, dhaawac kelyo ah) | Aan sun ahayn marka si buuxda loo bogsado (laakin hadhaaga formaldehyde ayaa laga yaabaa inay walaac yeelato) |
4. Codsiyada
- Melamine
- Walxaha ceeriin ee xabagta melamine.
- Dab-dejinta ololka (marka lagu daro fosfatetada).
- Melamine Resin
- LaminatesDusha sare ee miiska, alaabta guriga (tusaale, Formica).
- Alaabada cashada: Qalabka miiska ee melamine (wuxuu u ekaysiiyaa poselin laakiin miisaankiisu yar yahay).
- Xabagta & Dahaarka: Xabag alwaax ah oo biyaha u adkaysta, dahaarka warshadaha.
- Dharka & Warqadaha: Waxay hagaajisaa laalaabkii iyo caabbinta ololka.
5. Kooban
| Dhinac | Melamine | Melamine Resin |
| Dabeecadda | Unug yar | Polymer (isku-tallaabta ku xidhan) |
| Xasilooni | milma, qudhuntaa | Thermoset (aan la milmi karin marka la daaweyo) |
| Adeegsada | Hordhac kiimiko | Alaabta u dambaysa (caagagga, dahaarka) |
| Badbaadada | Sun ah qiyaas sare | Badbaado haddii si habboon loo daweeyo |
Xabagta Melamine waa nooca melamine-ka ee faa'iido u leh warshadaha, oo bixisa adkeysiga kulaylka, halka melamine saafi ah ay tahay dhexdhexaad kiimiko oo leh codsiyo toos ah oo xadidan.
