Kusiyana Pakati pa Melamine ndi Melamine Resin
1. Mapangidwe a Chemical & Mapangidwe
- Melamine
- Njira ya mankhwala: C3H6N6C3H6 ndiN6 ndi
- Kaphatikizidwe kakang'ono ka organic kokhala ndi mphete ya triazine ndi ma amino atatu (-NH2−NH2) magulu.
- White crystalline ufa, wosungunuka pang'ono m'madzi.
- Melamine Resin (Melamine-Formaldehyde Resin, MF Resin)
- Thermosetting polima yopangidwa ndi condensation reaction ya melamine ndi formaldehyde.
- Palibe njira yokhazikika yamankhwala (mawonekedwe olumikizana ndi 3D network).
2. Kaphatikizidwe
- Melamineamapangidwa m'mafakitale kuchokera ku urea pansi pa kutentha kwakukulu ndi kupanikizika.
- Melamine Resinamapangidwa pochita melamine ndi formaldehyde (yokhala ndi zopangira ngati asidi kapena maziko).
3. Katundu Wofunika
| Katundu | Melamine | Melamine Resin |
| Kusungunuka | Zosungunuka pang'ono m'madzi | Insoluble pambuyo kuchiritsa |
| Kutentha Kukhazikika | Imawola pa ~ 350°C | Zosamva kutentha (mpaka ~ 200°C) |
| Mphamvu zamakina | Brittle makhiristo | Zolimba, zosagwirizana ndi zokanda |
| Poizoni | Poizoni ngati atalowetsedwa (mwachitsanzo, kuwonongeka kwa impso) | Zopanda poizoni zikachiritsidwa bwino (koma zotsalira za formaldehyde zitha kukhala zodetsa nkhawa) |
4. Mapulogalamu
- Melamine
- Zopangira za melamine resin.
- Flame retardant (pamodzi ndi phosphates).
- Melamine Resin
- Laminates: Ma Countertops, mipando (monga Formica).
- Zakudya zamadzulo: Melamine tableware (amatsanzira zadothi koma zopepuka).
- Zomatira & Zopaka: Guluu wamatabwa wosagwira madzi, zokutira zamafakitale.
- Zovala & Mapepala: Imalimbitsa makwinya ndi kukana moto.
5. Mwachidule
| Mbali | Melamine | Melamine Resin |
| Chilengedwe | Molekyu yaying'ono | Polima (zolumikizana) |
| Kukhazikika | Zosungunuka, zimawola | Thermoset (yosasungunuka ikachiritsidwa) |
| Ntchito | Chemical kalambulabwalo | Chomaliza (pulasitiki, zokutira) |
| Chitetezo | Poizoni mu mlingo waukulu | Otetezeka ngati atachiritsidwa bwino |
Melamine resin ndi ma polymerized, ofunikira m'mafakitale a melamine, omwe amapereka kulimba komanso kukana kutentha, pomwe melamine yoyera ndi mankhwala apakatikati omwe sagwiritsa ntchito mwachindunji.
