Sewage tank anti-corrosion process flow
The erection of scaffolding - base springboard, completely dry environment temperature and humidity detection - 2 times - paint brush bottom putty repair - paste glass steel layer - brush bottom coating again - repair putty paste -- glass steel layer - brush bottom putty coating again - Repair - brush face painted 2 times - final inspection repair and maintenance, curing -
The main steps: sewage tank anti-corrosion treatment to sewage tank platoon in clear water tank of sewage 1 first we anticorrosion work before the start of 2; ground treatment by grinding machine dehairing wall, so that the bottom coating epoxy materials to fully penetrate into deep layer of cement; 3 glass fiber cloth tile on the bottom coating, and then brushing a layer of resin in glass fiber cloth, each layer of cloth brushing a layer of resin, do comprehensive, uniform, no bubble; 4 to be coated after the resin curing, grinding machine with full grinding flat and clean the dust, the deployment of anti-corrosion paint materials according to the proportion of good mixing; 5 after a certain period of time. Let the pool anticorrosive paint all confirm after drying, check all kinds of facilities to normal after injection into the pool.
Sewage tank anti-corrosion tools and raw materials: cleaning tools, grinding machine, roller, anti-corrosion primer material, fiberglass cloth, resin
Construction method and steps for anticorrosion of sewage tank
1 first of all, we should start the work of cleaning the tank before the start of the water tank, and a comprehensive cleaning, so as to avoid the debris in the pool of preservatives to play a certain impact.
2 factors to deal with first grinding machine with textured wall, so that the bottom coating epoxy materials to fully penetrate into deep layer of cement, epoxy resin to enhance adhesion to the maximum, so as to ensure the life of epoxy coating. Then use the roller will be deployed in a good anti-corrosion primer material evenly on the su * * * *, so as to completely penetrate the soil and fully bonded, so that the formation of a layer of resin bottom.
3 glass fiber cloth flat in the bottom coating, and then brush a layer of resin in glass fiber cloth, each layer of cloth brushing a layer of resin, do comprehensive, uniform and free of bubbles. After the glass fiber layer is completely cured, the surface burr and the material point are removed. And then the deployment of a good anti-corrosion coating material with the drum evenly coated on the glass fiber layer, so that the formation of a complete, covered with colored resin layer.
4 after the coating resin after curing, grinding machine with full grinding flat and clean the dust, the deployment of anti-corrosion paint materials according to the proportion of good mixing, roller coating, smooth and bright, dust removal, formation pressure, surface corrosion resistance of permanent.
5 over a certain period of time, so that the pool of anti-corrosion paint are all recognized after the dry, check a variety of facilities are normal, the water into the pool, take water samples to the city health and epidemic prevention inspection laboratory forensics, capping the lock. Tidy up the relevant work tools, clean up the site of waste.
