Fuzhou building waterproof materials in common requirements

Buildings and structures of waterproof is rely on waterproof performance of material, waterproof material quality fit and unfit quality directly related to the waterproof layer of durable fixed number of year. Waterproof engineering depends largely on the quality of waterproof material quality and performance of materials is the basis of waterproof engineering. We in the waterproof project construction, the waterproof materials used must conform to the state or the material quality standard of the industry, and should meet the design requirements. But different waterproof, waterproof function requirements for materials should be different. Fuzhou waterproof material in common requirements as follows: (1) has excellent weather resistance, light, heat, ozone, etc should have a certain capacity; Second, the resistance to water penetration and acid-proof alkaline can; Three, to the outside world has certain adaptability, temperature and external forces that materials have higher tensile strength, elongation at break, can withstand the temperature change as well as a variety of external force and deformation caused by expansion, cracking at the grass-roots level; Fourth, integral sex is good, can not only keep their own bondability, can with strong bond at the grass-roots level again, at the same time under the action of external force, high peel strength, form the impervious overall stability. For different parts of the waterproof engineering, the waterproof requirement also have their focus, specific requirements are as follows: one, the roof waterproof engineering of waterproof materials its weather resistance, resistance to temperature, the performance of the external force is particularly important. Because of roofing waterproof layer, especially without insulation layer exposed the waterproof layer of long-term suffering from wind, rain, sunshine, snow and other bad natural environment and basic structure of the deformation influence; Second, underground waterproof engineering of waterproof material must possess excellent permeability resistance and elongation, good overall waterproofness. These requirements are for groundwater erosion, and water pressure is bigger, and the distortion of the structure may be produced, and put forward the condition of Waterproof engineering chooses between the three, indoor toilet waterproof materials should be appropriate to the primary shape change and help the laying of pipeline equipment, with excellent waterproofness, jointless overall coating is most ideal. This is for the area is small, more wall tube piercing, Angle of Yin and Yang, health equipment and other factors connected to the ground, floor, wall structure more complex and so on the characteristic of; Four, building cladding joint waterproof engineering waterproof materials should be chosen with good weatherability, Gao Yanshen rate and bondability, sag resistance and other properties of the material, generally choose the waterproof heat preservation and heat insulation sealing materials supplemented by liner material to form a complete set of processing is advisable. This is considering to withstand heat preservation, heat insulation, waterproof wall comprehensive function needs and aperture structure connection is put forward in the special form; Five, the special structure of waterproof engineering fuzhou waterproof materials should be chosen according to different engineering characteristics and functions of different requirements, selected by design, as appropriate.
