Description
The present invention relates to a water-soluble ceramic composition for waterproofing or anticorrosion of water and sewage wastewater structures and a method for waterproofing or anticorrosion of water and sewage wastewater structures using the same.
In general, the waterproof method of the structure includes an asphalt sheet method, synthetic rubber sheet method, polyurea method, polyurethane method. Asphalt sheet method is a waterproof method for attaching asphalt sheet to the waterproof layer after the first and second liquid waterproofing is applied to the concrete structure. Although it is inexpensive and has a constant thickness, the asphalt sheet and the adhered surface (attached from the structure It has a weak adhesive force with the surface), has a poor adhesion rate at the joint portion of the asphalt sheet and the asphalt sheet, has a weak temperature dependence and low workability, and has a disadvantage of causing physical property changes in the asphalt sheet when heat-sealed.
Synthetic rubber sheet method is a waterproofing method that attaches a synthetic rubber sheet to a concrete structure after applying a primer to the primer, the thickness is constant and the crystal is stable, but during construction, the adhesive to the coating (the surface to be applied on the structure) After applying and applying the adhesive to the synthetic rubber sheet itself, the synthetic rubber sheet is attached to the structure, in which the adhesive is applied, and after exactly 3-5 minutes has a disadvantage that the synthetic rubber sheet to be attached to the workpiece. If this construction time is not observed, the synthetic rubber sheet will not adhere correctly to the structure. In addition, about two months after the production of the synthetic rubber sheet, the synthetic rubber sheet becomes hard and cannot be used. In addition, the synthetic rubber sheet method has a disadvantage that it is difficult to apply to a structure having a wet base surface because the adhesive is applied to the structure. In addition, the synthetic rubber sheet method has a disadvantage in that when the synthetic rubber sheet is firmly attached to the structure, the synthetic rubber sheet does not correspond to the behavior of the structure and is torn during the structure behavior.
Polyurea process is based on the concrete structure, and the primer is applied to the base surface, and the polyurea, which is an elastic material, is mixed and sprayed at high temperature and high pressure on the primer to apply the elastic film to the coated object (the surface to be applied in the structure). As a waterproofing method to be formed, it has excellent water resistance at construction and no joints, but has a problem of generating a pin hole phenomenon due to bubble generation, and has a hassle to smoothly surface the base surface of the structure. . In addition, the polyurea method has a disadvantage in that the waterproof film is formed into a thin film, which is weak in the behavior of the structure and difficult to be installed in the protruding portion or the wet base surface of the structure, and is difficult to be installed underground in the organic solvent type. Polyurethane method is based on the concrete structure, and the primer is applied to the base surface, and the primer is applied to the primer by mixing the organic solvent type and the curing agent, which can be applied to the wet base surface, but the surface of the base surface It has the disadvantage of requiring a lot of cost in processing. In addition, the polyurethane method is difficult to form a thick waterproof layer on the vertical surface, in this case has the disadvantage of having to repeat a thin thickness of the construction several times, it is a self-leveling type such as organic solvents to be installed on the vertical or inclined surface of the structure It has a disadvantage that is difficult to do. In addition, the polyurethane method may use tar urethane of a highly toxic carcinogen.
