Description
Technical field
The present invention relates to a kind of tun for material storing or transportation and manufacture method thereof, relate in particular to a kind of freight container and manufacture method thereof.
Background technology
General large-scale storage or transportation device, as the envelope of freight container, Fang Cang, trailer or superimposed trailer, its main components is all generally steel, for preventing corrosion, guarantee its normal service life, all will carry out coating to framing member with coating in the mill and cover processing.
The most frequently used coating is that solvent based coating is oily varnish at present, owing to containing a large amount of organic solvents or diluent in oily varnish, they can constantly evaporate in air and environment on every side in the coating film forming procedure and go, especially when the summer high-temperature operation, the volatility of organic solvent is very large, make workshop be studded with unpleasant noxious odor, these volatilization gas of while run into naked light and are easy to burning, this namely causes a large amount of wastes of solvent, also environmental and human health impacts is exerted an adverse impact, and have larger potential safety hazard.Simultaneously, environmental protection is all constantly being strengthened in countries in the world, environmental regulation as China is made explicit stipulation to the improvement of ' three wastes ' (waste gas, waste liquid, waste residue), to not meeting effluent standard and administering ineffective enterprise and make severe punishment, order even plant shutdowns etc. as fine, suspending operations for consolidation.
At present, also there are some technical difficult problems in the application of water paint in freight container: at first, because the existence of moisture in water paint, even if the surface treatment of process sanding, when the construction spraying, the surface of freight container still is easy to form rust spot; They are two years old, because with respect to organic solvent, water paint is as main dispersing medium with water, its volatilization, rate of drying than oily varnish slowly many, if press the existing fast pace coating of freight container construction technology, be difficult to guarantee its long-term antiseptic property, and can occur after the coating film forming, the moisture of part to be enclosed in dry coating, cause the not good and disadvantage such as easily come off of filming of sagging, bubble, adhesive ability; Also have, freight container produces many weld seams in the welding assembly process, and these places especially easily produce the disadvantages such as some rust, pin hole as the surface deficiency of metallic material when spraying.

Do:
1., to metal substrate (preliminary structure of side plate, end wall panel, top board), corner post, top beam, carry out sand-blast finish;
2., metal substrate is drawn, is pressed into various types of corrugated platings;
3., the correspondence position of top beam of laterally, top beam and corner post is implemented welding, welding box body is become the frame body of hexahedron structure;
4., will make the metal substrate of all kinds corrugated plating and the hexahedron frame body is implemented welding, make the casing assembly.
Having carried out in steps after, to finish paint in interior spraying water-based, levelling post-drying.
Sandblast to surface finish is the Sa2.5 level.
Water-based precoating rust proofing primer applicable viscosity is controlled at 10-30s, and the spraying build is controlled at 10-15 μ m, and spraying post-drying temperature is 70-120 ℃, and 1-5min is to surface drying in baking.
In aqueous priming paint, water-based intermediate layer paint, water-based, the applicable viscosity of the outer finish paint of finish paint and water-based is controlled at 20-80s, and each coating dry film THICKNESS CONTROL is at 30-50 μ m, and after spraying, levelling 3-10min is dried 3-20min in 70-120 ℃ of drying room.
The construction of water-based precoating rust proofing primer is adopted without gas automatic coating mode, and the employing nozzle diameter is 0.38-0.64mm, and spray pattern fabric width 200-360mm, high pressure pump intake pressure are 1-2kg/cm
2
Adopt in the outer finish paint construction of finish paint and water-based in aqueous priming paint, water-based intermediate layer paint, water-based without gas automatically and the hand spray mode that combines, the employing nozzle diameter is 0.38-0.64mm, and spray pattern fabric width 200-360mm, high pressure pump intake pressure are 4-6kg/cm
2
In the outer finish paint of water-based precoating rust proofing primer, aqueous priming paint, water-based intermediate layer paint, water-based and water-based, to be based on respectively main film forming substance be a kind of in aqueous epoxy resins, waterborne polyurethane resin, water-borne acrylic resin class coating to finish paint, or the compound of at least two kinds in aqueous epoxy resins, waterborne polyurethane resin, water-borne acrylic resin class coating.
The residing environment of workpiece after spraying is set up drafting apparatus, and the flowing velocity that makes ambient air is 0.20-0.80m/s.
The residing environment of workpiece after spraying arranges desiccant, makes the humidity of ambient air not higher than 75%.
Desiccant is at least at least a in these three kinds of solid driers of anhydrous calcium chloride, Roman vitriol and discolour silica gel.
The present invention is owing to having adopted the freight container parts such as corrugated plating that contain the water paint layer, and its advantage is: (1) does not contain organic volatile ingredients, the living environment of community around having improved; (2) saved the expense that organic solvent and diluent are reclaimed and administer; (3) easy to clean of Spray painting tool as spray gun, join paint can, mixer etc., only needs a tap water just can clean up;
The present invention under the prerequisite of improving workman's construction environment, has improved the safety of operation in workshop owing to having adopted new spraying method.Burn when meeting naked light, the probability of the industrial accident such as blast reduces greatly than solvent-applied type coating.By spraying water-based precoating rust proofing primer, sealed the contact of metal substrate with airborne moisture/oxygen, effectively suppressed the formation of some rust; By coating prebake, make the middle moisture evaporation of filming must be more complete, thereby avoid or reduced occurring the not good disadvantage such as easily come off of filming of bubble, adhesive ability in filming; By the coating rust proofing primer of secondary sanding, the deficiencies such as weld appearance point rust, pin hole have been prevented.Enhance productivity thereby reach, guarantee the purpose of product design.
