The code of controlled state on the date of release of the literature name rusted painting technologies was used in our company's production of rust removal paints for parts of the crane. 1 if the surface of the metal is hydro, oily, dusty before rusty, compressed air, scrubbing solvent drying or defamining. 1. 2. Removal of rust, skin oxide, sludge, welding, splatter, etc. (the presence of a small amount of iron oxide skin left in the netting area and the manual removal of a small amount of skin oxide left in the pelvis is difficult to remove when the pelvis is allowed). 1. 3. The surface of the platinum metal shall be carefully blown out of compressed air. 1. 4. The principle of surface rustification is set out in the following table: st2 manual solutions to rusty surface clean-up by rusty grade, using such measures as hand-made sandpaper grinding and wire brushing, mechanical brush grinding, to the point where no visible oil stains or stains are present and not attached to impervious skin oxidation and rust. The surface of the steel is covered with rust and dust with a clean, dry air compression or clean brush. St3 uses hand-made sandpaper grinding and wire brushes, mechanical brush brushes, etc., and sand wheel grinding measures to address surfaces more thoroughly than sa2. The bottom surface shows metallic glitter and does not allow welding, splattering, flying edges, stabbing, etc. Sa1 solution to light spray, removing oxidizing, rust and alien. Sa2 completely resolved the spray and removed the oxidized skin, rust and foreign matter. Sa2 1/2 was completely resolved by removing oxidizing skin, rust and foreign matter, leaving only slight plaster spots and stripes. Sa3 was treated with pure metal surface plasters, which were completely removed from oxidized skin, rust and foreign matter. The relevant grade, rating and determination of the mass of the crane's critical components (main beam, end beam, industrial steel track) in accordance with the gb8923. 1-principle shall be up to the level of sa21/2 or st3 and the rest up to the level of sa2 or st2. General provision 2. 1. 1 on spraying shall generally be painted except for the interior surface of the welded, non-metalized, non-ferrous metal, hair (blue), plating, stainless steel, and the unprocessed surface of the other parts and components. 2. 1. 2 once the casting, welding, etc. Has been tested for clearance, surface cleaning and lacquering shall be performed immediately. 2. 1. 3 the external mass has an impact on the local dents, scars, etc. On the surface of the spare parts, which should normally be compensated by a combination of good acreage, which, after grinding, should be flat, smooth, linear and clear throughout the surface of the parts, and which should not be clearly scarred by their connection to the surface of the parts. 2. 1. 4 core welding and critical welding do not allow the filling of grubs. 2. 1. 5 the assembly shall be followed by an impassioned lifting of parts and components, which shall be painted prior to assembly. Welding will be required for the assembly, which will be preceded by only laminated and not painted. 2. 1. 6 when filling, testing, adjusting, and if a paint membrane is touched, the touch plaster shall be removed and coated with a similar properties, colours, etc., before performing the next painting. 2. 2 regulation 2. 2. 1 on the mass of coatings and ontires shall be accompanied by the use of various coatings and assistive materials, such as coatings, antics, diluents, etc. 2. 2. 2 the coatings entering the plant shall be certified. Undefined plates, undefined models and qualities, broken packaging, lack of specific manufacturer paints and auxiliary materials are not allowed into the bank. Stockpile coatings exceed storage periods and are not allowed for use without authentication. 2. 2. 3 the coating shall be prepared in original drums or clean and clean capacitors. 2. 2. 4 two (or more) coatings or the same brand coatings may not be used in combination without an experimental certificate. 2. 2. 5 the ratio of paint to diluent pre-painting is 3:1. 2. 3 to address surface defects such as the curvature requirement 2. 3. 1 castings, the need for the exercise to be plastered, and the inadmissibility of visible tectonic cones, stings, sharp edges and embroidery marks. 2. 3. 2 the surface of the welded building parts shall not be allowed to suffer from surface defects such as welding, splattering, pellets, flying edges, stings, sharp edges, etc. 2. 4 caution: (1) a post-retardation plaster shall be used to blow off the surface with a trachea to remove rust from the surface before the subsequent process is resolved. (2) for the purpose of ensuring a combination of the main beams and the end beams with the plate plate, no paint is painted here, no rust is required during the manufacturing process for the paint works environment, which is not less than 4°c; the relative humidity is not less than 85%. 2. 4. 1 the next coating shall be carried out only after the previous coating has been dried. 2. 4. 2 multi-colour paints and coatings with heavy pigments shall be evenly mixed before use. 2. 4. 3 painting tools (painting, spray guns, paint drums, spraying equipment and piping) shall be kept clean. 2. 4. 4 condensed air for spray paint shall be clean and dry. 2. 4. 5 before the coating is dry, it shall be protected against adhesive oil, water, ash, sand or other stains, and shall not enter or assemble. For each of the two-and-a-half coatings, a visual inspection of the paint is required, which stipulates that there shall be no defects such as fall (floating), rough surfaces, slow drying and re-adhesives, bubbles, laughs (shrimp), orange skins, rust. In the event of such deficiencies, factors must be identified and preventive measures must be applied before the next process can be completed. 2. 5. 2 red dan paints are sprayed three times, coating paints are coated with a thickness of 25 ~ 35 μm per layer and a total thickness of 75 ~ 105 μm. 2. 6 paint quality check 2. 6. 1. The principles for paint quality inspection are set out in the following table: paint coating project painting project painting project painting project painting project painting project painting project painting project a small amount of coated skin allows small amounts of wrinkled cams to exclude small amounts of cavity foam to exclude small amounts of cavities and cavities to prevent diaphragms from covering sandy eyes scars does not allow cracking 2. 6. 2. 2 using spot-check detection methods, the number of spot-check points per product should not be lower than five. An average of no less than 90 per cent of the total thickness and no more than 120 per cent of the total thickness, and a minimum of no less than 70 per cent of the total thickness, is measured at each point. 2. 6. 3 the paint membrane is examined with a special knife and six vertical lines of 2 mm. As the figure shows, the knife marks are to be cut to the steel plate. The cutting knife shall be applied vertically to the cutting plane and evenly applied. Cuts at 20-50 mm/s, then swipes along the square graphic diagonal line with a soft brush and brushes forward five times back. The following table also describes the content of the platinum and determines the concentration of the paint sheet on the quality level. Provides for the first level. Quality requirements at the surface appearance level of the cutting area are stated at the intersection of the cut, with a small amount of thin strips on the coating, with no greater than 5% of the area of the coating being detached, with a significant loss along the cutting edge or cross, with an area of more than 5% and less than 15%
