Paint release control of brush

摘要

Paint release rate is an important indicator for evaluating the property of the paint product, which is predetermined by the brush and paint materials. In the painting process, a brush is always used to coat the liquid materials on the solid base surface. The brush fiber with different wettability, flexibility, and geometrical size affects the appearance, stability, and solidification velocity of paint. In this study, a kind of polyethylene terephthalate/polybutylene terephthalate-based brush is successfully fabricated, whose flexibility is adjusted by the content of fiberglass. The flexibility and appearance dimensions are proved to be the critical factors for enhancing the paint release rate through theory analysis and examples. With the designed brush, liquid coating materials with different surface tension are coated on the paper surface, whose effects are precisely controlled.
