Abstract:The influences of guide rod, thickener, coatings solid content and pigments formulation of coatings on curtain stability in curtain coating were studied. The results showed that the stability of curtain could be improved by increasing the binding force between coatings and guide rod. For the coatings without surfactant, when PVA dosage was 1.5 parts, the operational minimum flow increase from 1.64 c m2/s to 3.07 c m2/s; for coatings with surfactant, when PVA dosage increased from 0.5 part to 1.5 parts, the operational minimum flow decreased from 1.95 c m2/s to 1.55 c m2/s. Coatings solid content had a little effects on curtain stability. When clay content increased from 20 parts to 40 parts, the operational minimum flow increased from 1.92 c m2/s to 2.24 c m2/s.
