Kusiyana Pakati pa Melamine ndi Melamine Resin
1. Kapangidwe ka Mankhwala ndi Kapangidwe kake
- Melamine
- Fomula ya mankhwala: C3H6N6C3H6N6
- Kapangidwe kakang'ono ka organic komwe kali ndi mphete ya triazine ndi ma amino atatu (−NH2−NH2) magulu.
- Ufa woyera wa kristalo, wosungunuka pang'ono m'madzi.
- Melamine Resin (Melamine-Formaldehyde Resin, MF Resin)
- Polima yotenthetsera yomwe imapangidwa ndi melamine ndi formaldehyde zomwe zimasungunuka.
- Palibe njira yokhazikika ya mankhwala (kapangidwe ka netiweki ya 3D yolumikizidwa ndi mtanda).
2. Kupanga
- Melamineimapangidwa m'mafakitale kuchokera ku urea pa kutentha kwakukulu ndi kupanikizika.
- Melamine ResinAmapangidwa pochita zinthu ndi melamine ndi formaldehyde (yokhala ndi zinthu monga asidi kapena maziko).
3. Katundu Wofunika
| Katundu | Melamine | Melamine Resin |
| Kusungunuka | Kusungunuka pang'ono m'madzi | Kusungunuka pambuyo pochiritsidwa |
| Kukhazikika kwa Kutentha | Zimawola pa ~350°C | Yosagwira kutentha (mpaka ~200°C) |
| Mphamvu ya Makina | Makristalo Osalimba | Yolimba, yosakanda |
| Kuopsa kwa poizoni | Poizoni akameza (monga kuwonongeka kwa impso) | Sizimayambitsa poizoni zikachira bwino (koma formaldehyde yotsala ikhoza kukhala vuto) |
4. Mapulogalamu
- Melamine
- Zipangizo zopangira utomoni wa melamine.
- Choletsa moto (ikaphatikizidwa ndi phosphates).
- Melamine Resin
- Ma Laminate: Ma Countertops, mipando pamwamba (monga Formica).
- Zakudya zamadzulo: Zakudya zophikira za Melamine (zofanana ndi za porcelain koma zopepuka).
- Zomatira ndi Zophimba: Guluu wamatabwa wosalowa madzi, zokutira za mafakitale.
- Nsalu ndi Pepala: Zimathandiza kuti makwinya ndi moto zisawonongeke.
5. Chidule
| Mbali | Melamine | Melamine Resin |
| Chilengedwe | Molekyulu yaying'ono | Polima (yolumikizidwa ndi mtanda) |
| Kukhazikika | Sungunuka, imawola | Thermoset (yosasungunuka ikakonzedwa) |
| Ntchito | Choyambitsa mankhwala | Chogulitsa chomaliza (mapulasitiki, zokutira) |
| Chitetezo | Poizoni pa mlingo waukulu | Otetezeka ngati atachiritsidwa bwino |
Utomoni wa Melamine ndi mtundu wa melamine wopangidwa ndi polima, wothandiza kwambiri m'mafakitale, womwe umapereka kulimba komanso kukana kutentha, pomwe melamine yeniyeni ndi mankhwala omwe amagwiritsidwa ntchito pang'ono.
