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.

对于快干性的油漆适合使用性差，若操作不技术纯熟，漆膜易萌生裂痕，流挂和翘棱均等欠缺。

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、喷油漆用专用喷油漆枪作为工具，以压缩空气为送漆汽流，将油漆从喷枪的喷咀中喷成平均雾状液体，平均散布淤积在物体外表称为喷油漆。

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.

喷油漆的独特的地方是：漆膜薄而平均、光溜平整，各种部位都能喷到，不出死角儿，动工速率高，比刷漆增长工效5－10倍，适合使用于大平面或物体表面的大小的外表及人工不易涂刷的死角儿畸型外表。

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：需具有喷油漆的专用设备、油漆利用率低、污染严重。喷油漆动工的品质主要决定于于操笔者的技术技术纯熟程度，油漆粘度、办公大气的压力、喷枪与物体的距离。

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.
