As long as there is a place for construction work, there must be waterproof materials, and there are many types of waterproof coatings. According to the performance of different waterproof coatings, there is also a particular emphasis on building. Today, we will briefly explain how to use building waterproof materials correctly and reasonably.
Correct selection and rational use of building waterproofing materials
Due to the variety and performance of waterproof materials, waterproof materials have different advantages and disadvantages. They also have corresponding scope and requirements, especially the promotion and use of new waterproof materials, and should master the knowledge of this side. Proper selection and rational use of building waterproofing materials is the key to improving the quality of waterproofing, and also the premise of design and construction. Pay attention to the following points:
1. Material properties and characteristics
Building waterproof materials can be divided into two categories of flexibility and rigidity. The flexible waterproof material has high tensile strength, large elongation, small quality and convenient construction, but the operation technology is strict, and the puncture resistance and aging resistance are not as good as the rigid materials. The same is a flexible material, the coil is factory-produced. The thickness is uniform, the quality is relatively stable, the construction process is simple, and the work efficiency is high, but the equipment is more lapped, the joint is easy to be separated, and the construction of complicated surface and uneven base is difficult. . The performance and characteristics of waterproof coatings are just the opposite. The same is the coil, synthetic polymer coil, high polymer modified asphalt coil and asphalt coil also have different advantages and disadvantages. It can be seen that when selecting waterproof materials, attention must be paid to their performance and characteristics.
2. Building function and external environment requirements
After understanding the performance and characteristics of various waterproof materials, it should also be based on the type of building structure, waterproof structure and the external weather conditions of the joints (including temperature, humidity, acid rain, ultraviolet rays, etc.), and the structural form of the building (consolidation) Or fabricated) materials that are compatible with the determination of span, roof slope, degree of deformation of the foundation, and exposure to the waterproof layer.
3. Construction conditions and market prices
When selecting waterproof materials, construction conditions and market price factors should also be considered. For example, synthetic polymer waterproofing membranes can be divided into three categories: elastomers, plastomers and reinforced synthetic fibers, which are not only different in materials but also have great differences in properties. At the same time, it is necessary to consider the actual materials used in the local area. The effect of the use; the construction conditions such as the binder and construction process matched with the synthetic polymer waterproofing membrane should also be considered. Taking the waterproof coil as an example, the requirements for material selection are proposed. Similarly, there are many varieties of waterproof coatings and sealing materials, as well as various technical indicators, but the requirements for material selection are basically the same as above. In addition to the points mentioned above, the selection of materials should further consider whether the waterproof layer can adapt to the deformation of the base layer. Â
Scroll Saw is a compact electric saw that is designed to cut curves in wood, metal or other materials. The fineness of blades make it to cut more delicately than a jigsaw, and more easily than a hand coping saw. Like those tools, it is capable of creating curves with edges, by pivoting its table. Scroll saws always come with a thickness of up to 45 mm. This stationary saw is compact in size and boasts robust cast iron housing, making it extremely stable on the workbench.
