First, the correct understanding of rational use
In the waterproof coating engineering design, the first waterproof coating and its application technology to have a correct and comprehensive understanding of.
1 waterproof coating and waterproof coiled material are widely accepted and widely used in domestic and abroad. Due to the waterproof coating is a liquid material, it is particularly suitable for the construction of complex forms of the basic level, and can form a continuous waterproof layer, unlike the coiled material that there are a lot of lap joint.
2 waterproof coating in the forming process of waterproof layer, waterproof adhesive is subject and is closely linked, can make the waterproof layer and waterproof layer under the grass, no water "danger, and the day after the leak is easy to find, easy maintenance.
3 the waterproof coating layer can not be processed in the factory as the waterproof coiled material layer, but the construction site is transformed from the liquid material into the solid material. Although the extension of some materials to obtain a higher rate, but its tensile strength, tensile strength, friction resistance, puncture resistance and other indicators are lower than similar waterproofing materials, waterproofing paint must be added so the protective layer, and can not be referenced waterproofing materials of "empty shop" shop construction method. In the waterproof layer thickness, the waterproof coating is not as accurate control of the production of the factory by the factory, subject to the impact of human factors.
4 different varieties of waterproof coating, have different performance, use must be particularly careful.
5 by the waterproof coating of organic polymer, organic macromolecular compounds and complex organic compounds composed of many components, may be harmful to the human body, so in drinking water, swimming pool and cold water proof engineering design, must be carefully chosen. For containing coal tar and other harmful substances of paint, can not be used for the above project.
6 waterproof coating is not a universal material, in the waterproof project generally need to use with other materials. How to use www.szhuasheng.cn in the design of waterproof, Huasheng flexiblelinkageassistant seismic principle is a very important problem.
Two, pay attention to strengthening the protection of drainage
Dredge water, anti drainage, is one of the principles of various waterproof design, but the design of waterproof coating, there is a deeper meaning. Because the coating layer is generally thin, long soak in water, will be the phenomenon of reduced adhesion. The film emulsion coating curing the formation of long-term natural evaporation, water will occur after the swelling, the slope of drainage and drainage pipeline, we must pay great attention to avoid long-term water pool; design engineering in waterproof, should set up the protective layer on the waterproof coating and surface coating, in order to avoid long-term immersion in water; design of underground engineering waterproof coating at should, as far as possible to avoid the use of emulsion waterproof coating soaked in water after the poor performance for a long time.
Three, to ensure that the coating thickness
In order to ensure the quality of the project, different engineering and different coating have different requirements on the thickness of the coating. Due to the thickness of the coating has a great variability, and it is difficult to uniform, so the design can only determine an average thickness. Has a direct impact on the quality of waterproof coating thickness on the waterproof coating engineering, is also the most prone to shoddy construction links.
Four, local enhancement
In order to ensure the waterproof effect, the weak links in the waterproof engineering should be strengthened, this is the principle of waterproof design should be followed. Taking into account the thickness of the waterproof film is difficult to absolutely uniform, the design of the film when it is more attention to. The general approach is: in these areas to increase a certain area, a certain thickness of the reinforced coating, when necessary, can be matched with the seal, to achieve the purpose of enhancing local caulking material.
Five, the node part of the composite sealing treatment
With the sealing caulking material, composite use, is the basic principle of the application of waterproof coating. Such as pipe joints, joint deformation and penetration of prefabricated waterproof base or other components of the root of waterproof, waterproof coating alone is not enough, especially the use of rubber asphalt waterproof coating engineering, more need to adhere to this principle.
Six, to consider the factors of coating film
It is an important process in the construction of waterproof coating to change the coating from the liquid state to the solid state. The film forming process determines the quality of the waterproof coating, that is, the quality of the waterproof project. Therefore, in the design must be fully considered in the construction of the various factors that may affect the paint film.
Seven, coating adhesion conditions and coating protection layer of the guarantee
To make the adhesion of coating and base firmly, and get the paint thickness is uniform in the specified amount per unit area, there must be a relatively smooth, solid surface, when the reaction type and solvent type coating, base also has a certain degree of drying; Dangtu material composite with other materials or in use the seismic and other material adhesion, the designer must understand the compatibility between these materials, in order to ensure good adhesion between the waterproof material, so as to ensure the overall quality of waterproof engineering. In order to ensure the long-term effect of waterproof coating, waterproof coating is not the majority of Shenzhen Huasheng Company should use waterproof directly exposed, should set up the corresponding protective layer in the coating on the design.
