1. Painting: servants use brush to paint on the surface of objects, which is called painting. Its unique place is: saving paint, simple tools, easy to use, easy to master, strong flexibility. Lack is: labor intensity is big, yield is low.

對于快干性的油漆適合使用性差，若操作不技術純熟，漆膜易萌生裂痕，流掛和翹棱均等欠缺。

For fast drying paint, it is not suitable for use. If the operation is not skilled, the film is easy to crack, sagging and warping.

2、噴油漆用專用噴油漆槍作為工具，以壓縮空氣為送漆汽流，將油漆從噴槍的噴咀中噴成平均霧狀液體，平均散布淤積在物體外表稱為噴油漆。

2. Spray paint uses a special spray gun as a tool. Compressed air is used as the vapor stream to spray paint from the nozzle of the spray gun into an average mist liquid, which is evenly dispersed and deposited on the surface of the object. It is called spray paint.

噴油漆的獨特的地方是：漆膜薄而平均、光溜平整，各種部位都能噴到，不出死角兒，動工速率高，比刷漆增長工效5－10倍，適合使用于大平面或物體表面的大小的外表及人工不易涂刷的死角兒畸型外表。

The unique features of spray painting are: thin and even paint film, smooth and smooth, all parts can be sprayed, no dead corner, high construction speed, 5-10 times higher than painting efficiency, suitable for large plane or object surface size appearance and artificial not easy to brush dead corner deformed appearance.

欠缺是：需具有噴油漆的專用設備、油漆利用率低、污染嚴重。噴油漆動工的品質主要決定于于操筆者的技術技術純熟程度，油漆粘度、辦公大氣的壓力、噴槍與物體的距離。

The deficiencies are: special equipment for spray paint, low utilization rate of paint and serious pollution. The quality of the spray paint depends on the technical proficiency of the operator, the viscosity of the paint, the pressure of the office atmosphere, and the distance between the spray gun and the object.
