Color non standard screw paint

In addition to the different sizes and standard parts of the non standard screw, the surface color and treatment of the screws are also non-standard, such as colored paint screws. Today, the world-class screw manufacturers come to talk to you about what to do before the non-standard screws are painted.

non standard screw should pay attention to the following points before painting. First, we need to know what is spraying. Spraying is carried out by means of a spray gun or a dish atomizer, and is dispersed into uniform and fine-resistant droplets by pressure or centrifugal force. The method of coating the surface of the object to be coated.

Secondly, we need to understand the choice of metal spraying process. Metal spraying can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms, such as high flow low pressure atomizing spraying, thermal spraying, automatic Spraying, multiple sets of spraying, etc. Regarding the spraying treatment method, we should decide according to the use of different materials of non-standard screws.

Conventional non standard screw are pre-painted. Degreasing and degreasing→Washing→Pickling and derusting→Washing→Neutralization→Washing→Table adjustment→Phosphoration→Washing→Drying→Coating/ie electrostatic spraying (normally used for degreasing and degreasing, pickling and derusting processes) The process must be greater than 25 minutes).

1: When there is no rusted workpiece, the process is as follows. Pre-degreasing → degreasing → hot water washing → cold water washing → cold water washing → pre-setting → surface adjustment → phosphating → cold water washing → pure water washing → pure water washing.

2: When there is a rusted workpiece, the processing flow is as follows. Pre-degreasing → degreasing → hot water washing → cold water washing → pickling → cold water washing → surface adjustment → phosphating → cold water washing → pure water washing → pure water washing
