Putty spraying machine is a small machine that stirs, pumps and sprays high-quality putty powder. It is one of the spraying machines, mainly spraying various decorative putty produced at home and abroad.
Putty spraying machine is easy to use, spraying speed is not as fast as possible and uniform, and save a lot of material for other spraying machines first.
The following is an analysis of the putty spraying machine from four aspects: coating performance, spraying material type, spraying economic performance, and site construction adaptability:
1. When the coating requires high bonding strength and extremely low porosity, high-speed flame spraying can be used for metal or cermet coatings; high-speed plasma spraying can be used for oxide ceramic coatings.
2, Putty spraying machine performance requirements are high. For the expensive or critical components with severe working conditions, the plasma spraying process can be selected. Compared with oxyacetylene flame spraying, plasma spraying has a high flame temperature, sufficient melting, non-oxidizing, high coating bonding strength, and low porosity;
3. The spraying performance is not high, the use environment has no special requirements, and the melting point of the spraying material is lower than 2500 ° C. The oxygen-acetylene flame spraying process with simple equipment and low cost can be selected. Such as general workpiece size repair and conventional surface protection;
There are many spraying process methods, but each method has its own advantages and limitations. Selecting the spraying process from different angles will lead to different results. Spraying process selection In order to meet the coating requirements of parts, the appropriate spraying materials should be determined in consideration of the working conditions of the parts and the composition, performance, process characteristics, coating performance and applicable environment of various coating materials , carefully choose the spray process.
