Embodiment 1
[0016] Embodiment 1, engineering oil cylinder coating method, carry out according to the following steps: 1, polish: earlier use electric angle grinder band 80 mesh emery wheel slices criss-cross to polish oil cylinder surface once, then use electric angle grinder band 120 order emery wheel slices to adopt Grind the surface of the oil cylinder again in a criss-cross manner until there are obvious grinding traces on the surface. The traces at the cylinder head and the center clamp should be more obvious and the surface is dull and smooth. Surface profile: 30~40μm, c. The surface finish is grade 4~6; 2. Pre-degreasing: Use a paint brush to dip TNE-HX100 thinner to scrub the surface of the cylinder body once, and then use a cotton cloth to dip an appropriate amount of the same thinner to scrub the cylinder body once; 3. Degreasing Oil: Use a paint brush to dip in TNE-JX102 industrial cleaning agent to scrub the surface of the cylinder once; 4. Four-in-one phosphating, first use 8%...
