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.
