Dyes rau Plastics: Qhov tseem ceeb ntawm cov xim sib txawv
Dyes siv rau hauv cov xim yas yuav tsum ua tau raws li cov kev cai tshwj xeeb, xws li thermal stability, solubility, thiab compatibility nrog polymers. Hauv qab no yog cov xim zoo tshaj plaws rau cov yas, nrog rau lawv cov txiaj ntsig tseem ceeb thiab kev siv.
1.Solvent Dyes
Qhov zoo:
-Excellent Solubility nyob rau hauv Plastics: Dissolve zoo nyob rau hauv non-polar polymers (piv txwv li, PS, ABS, PMMA).
-High Thermal Stability (> 300 ° C): Tsim nyog rau kev ua haujlwm kub (txhaj tshuaj molding, extrusion).
-Transparent & Vibrant Colours: Zoo tagnrho rau cov pob tshab los yog cov khoom yas (piv txwv li, lo ntsiab muag, ntim).
-Good Lightfastness: Resistant rau UV fading nyob rau hauv ntau daim ntawv thov.
Kev siv:
-Acrylics (PMMA), polystyrene (PS), polycarbonate (PC), thiab qee cov polyesters.

2. Basic (Cationic) Dyes
Qhov zoo:
- Ci ntsa iab Fluorescent & Metallic Effects: Tsim cov xim zoo nkauj.
-Txoj kev sib raug zoo rau Acrylics & Hloov Polymers: Siv hauv cov yas tshwj xeeb.
Kev txwv
- Txwv rau cov polymers tshwj xeeb (xws li, acrylics) vim muaj teeb meem kev sib raug zoo.
Kev siv:
- Cov khoom siv zoo nkauj, cov khoom ua si, thiab cov ntawv acrylic.
