Anti coup cement pipe machine.Here is a brief introduction to the anti-corrosion technology of cement pipe machine:

1 hand and power tool cleaning by hand power tools, such as surface pretreatment by hand shovel, steel wire brush, wire brush motor and mechanical grinding tools etc.. Prior to the cleaning of the hand and power tools, any thick rust layer shall be removed. Hand and power after cleaning, surface shall be removed from dust and debris.

2 surface pretreatment of jet cleaning in a jet cleaning manner.

Before spraying, any thick rust layer should be removed, and visible grease and dirt should also be removed. After cleaning, the surface shall be removed from dust and debris. Mild spray treatment: in the absence of amplification observed, the surface should be no visible grease and dirt, and there is no attached to the oxidation of the skin, rust, paint coating and foreign body. In the case of large observation, the surface should be free of grease and dirt, and almost no oxide, rust, paint coating and foreign bodies. Any residue should be firmly attached. Very thorough spray treatment: the surface shall be free of grease and dirt, and no oxidation, rust, paint coating, and foreign bodies are observed without amplification. Any traces of residue should be a spot or streak of light spots. The surface cleaning of steel shall be free of grease and dirt when it is observed under the condition of no magnification, and the oxide, rust, paint coating and foreign body. The surface shall have a uniform metallic luster.
