Kev nthuav qhia kev lag luam |Precipitated Silica Applications
Txheej txheem cej luam
• Hydrochloric acid-processed silica (precipitated silica) yog siv dav hauv txheej txheej.
• Muab cov nyhuv matting, rheology tswj, thiab cov cuab yeej ua kom zoo dua qub.
• Ntau yam sib ntxiv: 1%–10%, nyob ntawm qhov gloss thiab qhov system yuav tsum tau ua.
Common Addition Range
• • Basic Matte Effect (1%-3%): Semi-matte tiav (30–60 GU)
• • Medium Matte Effect (3%-6%): Tag nrho cov matte tiav
• • High Matte Effect (6%-10%): Ultra-matte tiav rau cov ntawv thov tshwj xeeb
• • Muaj txheej txheej: 3%-10% rau cov kuab tshuaj semi/full matte EffectRecommended Dosage by Coating Type Coating Type Recommended Dosage Main Function Water-raws li acrylic xim 0.5%-2% Matting, rheology tswj UV-kho xim 0.5%-3% Matte 3% Matting nyhuv, txhim kho cov nyhuv Txhim kho kev xav Muaj xim hlau xim 3%-10% Matting, optimized nto khoom hmoov txheej 0.1%-0.5% Matting, txhim kho flowabilityKey Factors cuam tshuam rau noj
• • Matting Efficiency: nqaim particle loj, siab porosity (0.8–2.0 cm³/g) → +30% efficiency
• • System Compatibility: Hydrophilic rau waterbased (tsawg dua los yog sib npaug li 5%), Hydrophobic rau hnyav-raws li (tsawg dua los yog sib npaug li 15%)
• • Performance Balance: Avoid >15% ntxiv los tiv thaiv hardness reductionPractical Application Tips
• • Stir thoroughly before use for uniform dispersion • • High-speed dispersion (>2000 rpm) lossis xuab zeb milling pom zoo
• • Khaws rau hauv qhov chaw qhuav, qhov cua; kaw nruj nreem tom qab siv
• • Siv cov khoom seem nyob rau hauv 3 lub hlis Nqis nqi -Kev ua tau zoo
• • Precipitated silica ≈ 40% pheej yig dua fumed silica
• • Xav tau cov nyiaj ntxiv ntau dua (3%-10% vs. 0.5%-3%)
• • Xaiv raws li qhov xav tau gloss, system, thiab pob nyiaj siv
