Vainu'u mo Plastics: A'oa'oga Autu o Ituaiga Valu Eseese
O vali e fa'aaogaina i le palasitika valivali e tatau ona fa'amalieina mana'oga fa'apitoa, e pei o le mautu o le vevela, solubility, ma le fetaui ma polymers. O lo'o i lalo ituaiga vali sili ona lelei mo palasitika, fa'atasi ai ma a latou fa'amanuiaga autu ma fa'aoga.
1.Vainu'u Solvent
Tulaga lelei:
-Solubility Solubility i Plastics: Fa'amuta lelei i polymers non-polar (faataitaiga, PS, ABS, PMMA).
- Maualuluga Faʻasaʻo (> 300 ° C): E fetaui lelei mo le faʻaogaina o le vevela (faʻapipiʻi tui, extrusion).
- Lanu Malamalama & Vibrant: Lelei mo oloa palasitika manino pe faʻafefe (faʻataʻitaʻiga, tioata, afifiina).
-Malamalama Lelei: Faʻasaʻo i le mataʻutia o le UV i le tele o talosaga.
Fa'aoga masani:
-Acrylics (PMMA), polystyrene (PS), polycarbonate (PC), ma nisi polyesters.
O la matou fautuaga:
Solvent Samasama 21,Solvent Red 8,Solvent Mumu 122,Solvent Blue 70,Solvent Black 27,Solvent Samasama 14,Solvent moli 60,Solvent Red 135,Solvent Red 146,Solvent Blue 35,Solvent Black 5,Solvent Black 7,Fua lanu Samasama 21,Solvent Orange 54 fausaga,Solvent Vai lanu moli 54, ma isi.
2. Vainu'u Autu (Cationic).
Tulaga lelei:
-Brilliant Fluorescent & Metallic Effects: Fausia ni lanu mata.
- Lelei Affinity mo Acrylics & Modified Polymers: Faʻaaogaina i palasitika faʻapitoa.
Tapulaa
- Fa'atapula'a i polymers fa'apitoa (eg, acrylics) ona o fa'afitauli fetaui.
Fa'aoga masani:
- Palasitika teuteu, meataalo, ma ie fa'ailoga.
O la matou fautuaga:
