Project background and purpose
Pumps are widely used in the oilfield and are subjected to complex and harsh operating environments. They are susceptible to corrosion and deterioration, which can affect the use and operation of equipment or cause serious accidents resulting in irreversible economic damage and possibly threatening the lives of those involved.
Criteria for judging the results after spraying
1) Appearance check. The coating should be smooth and flat, with consistent colour and no defects such as pinholes, bubbles and flaking. Check with a 5-10 times magnifying glass, those without microporosity are qualified.
2) Coating thickness check: use a thickness gauge to determine, the coating thickness should be uniform, the coating thickness and number of layers should meet the design requirements.
(3) Adhesion check. Use fork method to check the adhesion of the coating, no flaking.
Note: a. Super double sparse antifouling coating has good adhesion to various coatings with low surface tension (with our self-developed adhesion promoter) and high surface tension, and the adhesion can reach grade 1.
b. Super double antifouling coatings are flexible coatings.
c. If the original coating itself does not peel off, the anti-icing coating will not peel off when applied to the original paint surface.
4) Hydrophobic performance check: method: use a dropper to drop water on the surface of the paint film, observe whether the water drops can roll off quickly in the form of water droplets, it is qualified if it can roll off quickly, otherwise it is not qualified.
