[0017] Mix and disperse 32kg diglycidyl phthalate, 3kg glycerol epoxy resin, 0.3kg dispersant BYK-108, 0.3kg defoamer BYK-141 and then add 1kg calcium hydroxide powder, 55kg 4,5- Dichloro-2-n-octyl-4-isothiazolin-3-one, 7.9kg iron oxide red, disperse at high speed for 15 minutes, add 0.5kg fumed silica TS-720 and disperse at high speed for 5 minutes, cool and pack to obtain Solvent-free underwater antifouling coating A component.
[0018] Clean up the marine organisms and other loose attachments near the waterline of the jacket, and use a pneumatic grinder to polish until smooth; use the solvent-free underwater anti-fouling coating component A and SUNMIDE I-965 according to the mass ratio of 5:1 After mixing, pour it into the coating machine, adjust the coating amount of the coating machine, so that the coating amount of the solvent-free underwater antifouling coating soaked in the polyester wrapping tape with a width of 10cm and 200g / ㎡ is 0.8kg / ㎡. The surface of the treated ...
