Qhov Sib Txawv Ntawm Melamine Thiab Melamine Resin
1. Cov Qauv Tshuaj thiab Cov Khoom Siv
- Melamine
- Cov mis tshuaj: C3H6N6C3H6N6
- Ib qho organic compound me me uas muaj lub nplhaib triazine thiab peb cov amino (−NH2−)NH2) pawg.
- Dawb crystalline hmoov, me ntsis soluble hauv dej.
- Melamine Resin (Melamine-Formaldehyde Resin, MF Resin)
- Ib qho thermosetting polymer tsim los ntawm cov tshuaj condensation ntawm melamine thiab formaldehyde.
- Tsis muaj cov mis tshuaj ruaj khov (cov qauv sib txuas 3D network).
2. Kev sib xyaw ua ke
- Melamineyog tsim tawm hauv kev lag luam los ntawm urea nyob rau hauv qhov kub thiab siab.
- Melamine Resinyog synthesized los ntawm reacting melamine nrog formaldehyde (nrog catalysts xws li acid los yog base).
3. Cov Khoom Tseem Ceeb
| Vaj tse | Melamine | Melamine Resin |
| Kev yaj tau | Me ntsis yaj hauv dej | Insoluble tom qab kho |
| Kev Ruaj Ntseg Thermal | Yaj ntawm ~ 350 ° C | Tiv taus cua sov (txog li ~ 200 ° C) |
| Lub Zog Kho Tshuab | Cov pob zeb tawg yooj yim | Nyuaj, tsis yooj yim khawb |
| Kev lom | Lom yog tias noj (piv txwv li, ua rau lub raum puas) | Tsis muaj tshuaj lom thaum kho tag (tab sis cov formaldehyde seem yuav yog qhov txhawj xeeb) |
4. Cov ntawv thov
- Melamine
- Cov khoom siv raw rau melamine resin.
- Tiv thaiv hluav taws (thaum ua ke nrog phosphates).
- Melamine Resin
- Cov laminatesCov txee saum rooj tog, cov rooj tog zaum (piv txwv li, Formica).
- Cov khoom noj hmoCov khoom siv rooj tog Melamine (ua zoo li cov porcelain tab sis tsis hnyav).
- Cov nplaum thiab cov tshuaj pleev xim: Cov kua nplaum ntoo uas tiv taus dej, cov tshuaj pleev xim rau kev lag luam.
- Cov Ntaub Ntawv & Daim Ntawv: Txhim kho qhov wrinkle thiab hluav taws tsis kam.
5. Kev Txheeb Xyuas
| Aspect | Melamine | Melamine Resin |
| Xwm | Lub molecule me me | Polymer (txuas nrog) |
| Kev Ruaj Ntseg | Yaj, lwj | Thermoset (insoluble thaum kho) |
| Siv | Cov tshuaj ua ntej | Cov khoom kawg (plastics, coatings) |
| Kev Nyab Xeeb | Tshuaj lom nyob rau hauv cov koob tshuaj ntau | Muaj kev nyab xeeb yog tias kho kom zoo |
Melamine resin yog cov polymerized, siv tau rau hauv kev lag luam ntawm melamine, muab kev ruaj khov thiab tiv taus cua sov, thaum melamine ntshiab yog cov tshuaj nruab nrab nrog kev siv ncaj qha tsawg.
