Temporary clips or rings, etc. must be removed before construction, and the area is polished smooth. After completion of the steel shell, and drawings by the German allowed for acceptance and delivery of anti-corrosion work. Equipment attached to the surface of the lining should reach the local level, at the corner of the transition should be smooth. Lobe surface radius greater than 5mm, concave surface angle should be larger than 10mm. Topical (including weld seams) irregularities should be less than 3mm, and after grinding through the shell thickness must be greater than the minimum thickness of the device design. Pitting, cracks surface defects, undercut, scratches, scaly skin, etc. must be polished cleared where necessary to repair by welding, soldering must be polished smooth, and can not be sandwiched slag, porosity. Construction blasting process a main selection of grit blasting construction 1.1 diameter 0.5-3.0mm dry, water chestnut ore. 1.2 blast gas is 0.5-0.8Mpa clean, dry compressed air. 1.3 Nozzle selection: wear nozzles. 1.4 sandblasting sandblasting wear clothes before work to check all lines intact smooth, we can carry out the construction work. 1.5 sandblasting order after the first hard easy, gun running direction and parallel to the surface of the workpiece when the gun work and the work of leaving it at an angle. 2.1 Clean ventilation during sandblasting dust proof axial fans with a powerful blast after two. 2.2 Surface and frame plates floating dust, sand first purged with compressed air to clean. Clean oil at 2.3 with styrene. 3 working area controlled climatic conditions: T = 10 ~ 40C ?? relative humidity (RH) <89% of various coating structure construction specifications a conventional glass flake coating structure (non-FRP reinforced structure). 1.1 Construction 1.1.1 primer primer construction using roller or brush, always check the construction process, sagging, leakage and other phenomena painted with a roller or brush to catch pressed flat or up brush. 1.1.2 construction process test wet film thickness of less than 60Um site up brush. 1.1.3 material preparation: (1) preparation of the ratio: Paint: initiator: accelerator = 100: 1.5: 0.8 (weight ratio) (or according to the climatic conditions are adjusted) (2) Preparation method: first primer stirred with a mixer uniform, then add an initiator, curing agent were mixed by stirring for 1-2 minutes; (3) Professional Ingredients member and the recording material of the batch ingredients, dosage. 1.1.4 Operation points: (1) the way to roll back and forth first by scrolling up and down, uniform materials. (2) corner or roller brush difficult construction site. Wet film thickness test per 10m2 (3) not less than 5:00, the wet film thickness of less than 60um parts painted up. 1.1.5 climate controlled work area :( standard requirements) 1.2 Construction of the first layer of grass-roots flake lining
