Definitions
- the invention relates to protective treatment methods for hollow bodies or hollow metal structures against corrosion.
- the metal structures in question here are large structures with difficult-to-access surfaces for depositing an anti-corrosion paint with a brush or a spray gun. They are hollow to reduce the weight.
- the invention relates to a corrosion protection treatment process of a hollow body with difficult access surface to preserve corrosion, comprising at least one step of injection into the hollow body of a cellular foam carrier an anti-corrosion agent and a flame retardant or thermal insulator.
- a mixture of a first expansion component of a second anti-corrosion agent support component is injected to produce the anti-corrosion foam and flame retardant or thermal insulation.
- the invention also relates to a method for producing a metal structure comprising the steps of: - assembling the structure and - anti-corrosion protection treatment difficult access surfaces of the structure according to the above method.
- This method is particularly suitable for the realization of metal structures of boxes (hollow bodies), floors or partitions of material rail or boats when at least one of the walls is metal and requires special anti-corrosion treatment.
- the invention finally relates to a method of maintenance of a metal structure by replacing a part of the structure, the structure also comprising at least one hollow body, protected by a cellular foam according to the method of the invention, and to minus a flammable element separated from the structural part to be replaced by the cellular foam, characterized in that, the cellular foam being a non-flammable thermal barrier, said structural portion is directly replaced without prior disassembly of said flammable element.
- FIG. 1 is a perspective view of a structure comprising surfaces that are difficult to access, to protect against corrosion and
- FIG. 2 is a perspective view of a railway car floor structure and which comprises a part to be repaired.
- a structure 1 liable to be subjected to corrosive attacks either by the ambient air or by the water, in particular during cleaning with the aid of detergents, comprises sheet blanks 2 , 3 or more, assembled by metal cleats 4, serving as spacers.
- the cleats 4 are hollow and have surfaces 5 which must be completely guaranteed of any corrosion but are difficult to access by brush or spray gun required for the deposition of a primary paint.
- a and B are simultaneously injected by means of a two-nozzle gun,
- A being a mineral foam foam to which an anti-corrosion agent and adhesion pigments have been added, and possibly flame retardants, thermal insulation, phonic, ... and B, a product causing the expansion of the cellular foam A, when A and B are in contact.
- component A transports the additional agents supported by the foam on all parts of the surfaces 5, even those that are out of sight, and guarantees their complete protection.
- Foamed foam A thus expanded remains in place after application to cover all surfaces, which waterproofs the structure 1 and contributes to its anti-corrosion protection. If necessary, it is possible to integrate an impervious elastic agent into the cellular foam A.
- a two-component mineral product is preferred, which is composed of either an ablative silicone, which is converted into energy-consuming, and intumescent, with formation of thermal insulating foam, or components minerals and usually two bases, for example a zinc phosphate and a limestone, such as calcium carbonate.
- ablative silicone which is converted into energy-consuming, and intumescent
- thermal insulating foam or components minerals and usually two bases, for example a zinc phosphate and a limestone, such as calcium carbonate.
- compositions proposed in PCT / BE 95.00106 forming an inorganic, adhesive, non-flammable resin layer, applied to the surface covering to be protected, for use with an expansion component set in sufficient proportion to obtain an expanded foam foam that can be expanded in proportions corresponding to the purpose sought here.
- the minerals used are composed mainly of combinations of phosphates and calcium carbonates, especially plasticizers such as dibutyl phthalate, dioctyl, cyclohexyl, or dimethylglucol, or such as benzyl benzoate, castor oil, ricinoleate glycerol or methyl, octyl adipate, heptanoate or pentaerythritol butyrate or dipropylene glycol, or glycerol or dipropylene glycol butyrate, camphor.
- plasticizers such as dibutyl phthalate, dioctyl, cyclohexyl, or dimethylglucol, or such as benzyl benzoate, castor oil, ricinoleate glycerol or methyl, octyl adipate, heptanoate or pentaerythritol butyrate or dipropylene glycol, or glycerol or di
- plasticizers which are also flame retardant, it is possible to choose from tricresyl phosphate, triphenyl phosphate or trichloroethyl phosphate.
- a filler such as hemp or other inexpensive components may be added.
- the quantity of product necessary, and therefore its cost, is reduced accordingly.
- pistol and products A and B make it possible to realize much better price a metal structure only by implementing the assembly steps of the structure 1, 2, 3, 4, and then treatment of the anti-corrosion protection of surfaces 5 difficult to access.
- the example of structure 10 of FIG. 2 here comprises a wooden floor 11 and a metal frame 12 in the image of the structure of FIG. 1. It comprises metal sheets 13 and 20 assembled by lateral cleats 15 (but they might as well be transversal).
- the sheet 20 is perforated and has functional orifices 21 for various fasteners to be used later. It is stiffened by a reinforcement profile
- the cleats comprise here openings 16 and the reinforcement profile 14, 17, openings 19 to facilitate the injection operations of the foam A in a hollow body 18 having difficult to access surfaces to protect.
- the deteriorated portion 23 of the torch portion 22 may be cut without having to disassemble the wooden floor portions 11, or any flammable element located nearby, or seats, carpet resting on this floor.
- the cellular foam A expanded in the hollow body 18 to protect it is interposed between the part 23 to be replaced and the floor 11, and, separating it from the part 23, insulates it thermally and protects it from the fire.
- the part 23 can be replaced by welding without dismounting the flammable element 11.
