Iyatọ Laarin Melamine ati Melamine Resini
1. Kemikali Be & Tiwqn
- Melamine
- Ilana kemikali: C3H6N6C3H6N6
- Apapọ Organic kekere kan pẹlu oruka triazine ati amino mẹta (-NH2-NH2) awọn ẹgbẹ.
- Funfun okuta lulú, die-die tiotuka ninu omi.
- Resini Melamine (Melamine-Formaldehyde Resini, Resini MF)
- Polima setting thermosetting ti o ṣẹda nipasẹ ifasilẹ condensation ti melamine ati formaldehyde.
- Ko si ilana agbekalẹ kemikali ti o wa titi (igbekalẹ nẹtiwọọki 3D ti o ni asopọ agbelebu).
2. Akopọ
- Melamineti wa ni iṣelọpọ ni ile-iṣẹ lati urea labẹ iwọn otutu giga ati titẹ.
- Melamine Resiniti ṣepọ nipasẹ didaṣe melamine pẹlu formaldehyde (pẹlu awọn ayase bi acid tabi ipilẹ).
3. Awọn ohun-ini bọtini
| Ohun ini | Melamine | Melamine Resini |
| Solubility | Die-die tiotuka ninu omi | Insoluble lẹhin curing |
| Gbona Iduroṣinṣin | Ti bajẹ ni ~ 350 ° C | Sooro ooru (to ~200°C) |
| Agbara ẹrọ | Awọn kirisita brittle | Lile, ibere-sooro |
| Oloro | Majele ti o ba jẹ wọn (fun apẹẹrẹ, ibajẹ kidinrin) | Ti kii ṣe majele ti o ba mu ni kikun (ṣugbọn formaldehyde to ku le jẹ ibakcdun) |
4. Awọn ohun elo
- Melamine
- Ohun elo aise fun melamine resini.
- Idaduro ina (nigbati a ba ni idapo pẹlu awọn fosifeti).
- Melamine Resini
- Laminates: Countertops, aga roboto (fun apẹẹrẹ, Formica).
- Ounjẹ ounjẹ: Melamine tableware (mimics tanganran sugbon lightweight).
- Adhesives & Awọn aso: Lẹ pọ igi ti ko ni omi, awọn ohun elo ile-iṣẹ.
- Awọn aṣọ & Iwe: Se wrinkle ati ina resistance.
5. Akopọ
| Abala | Melamine | Melamine Resini |
| Iseda | Kekere moleku | Polymer (ti a sopọ mọ agbelebu) |
| Iduroṣinṣin | Soluble, decomposes | Thermoset (ti ko ṣee ṣe nigbati o ba mu) |
| Nlo | Kemikali ṣaaju | Ọja ikẹhin (awọn pilasitik, awọn aṣọ ibora) |
| Aabo | Majele ti ni ga abere | Ailewu ti o ba mu daradara |
Resini Melamine jẹ polymerized, fọọmu ti o wulo ni ile-iṣẹ ti melamine, ti o funni ni agbara ati resistance ooru, lakoko ti melamine mimọ jẹ agbedemeji kemikali pẹlu awọn ohun elo taara to lopin.
