涂料工业：
涂料缺陷（Paint Defects）
七、干喷（Dry Spray）
漆膜表面粗糙和不均匀，颗粒没有足够的流动性，无法一起流动。这种涂层缺陷通常只有一小片范围。
Rough and uneven finish to the surface of the paint film where the particles are insufficiently fluid to flow together. This defect is normally limited to small areas.

2．可能原因（Probable Causes）:
不正确的施工方法如喷枪与施工面的距离不适当。也与产品本身干燥过快和过高的施工温度有关。
Incorrect spray application i.e. gun distance. Also associated with fast drying products and too high an application temperature.
使用正确的涂装设备和工艺。使用干燥较慢的溶剂或溶剂混合物。遵循推荐的施工程序。
Use correct coating application equipment and techniques. Use a slower drying solvent or solvent blend. Follow recommended application procedures.
Allow the paint to dry and then sand. After sanding, and depending on the magnitude of the defect, respraying or polishing will be necessary.Abrade and remove any loose dryspray and re-apply coating or topcoat.
