1, the importance of waterproof technology,Aluminium Foil 20mic for waterproofing

Waterproof technology is a special technology to ensure that the engineering structure is not eroded by water. It plays an important role in building construction. The quality of waterproof engineering will directly affect the life of buildings and structures, and affect the normal production. For a long time, waterproof engineering due to design, material selection, construction, settlement, deformation and many other reasons, the quality problem is very serious. Roofing, toilet, exterior wall panel seam and basement leakage have become the common quality problems of waterproof engineering. These quality problems light cause roof and cornice leakage paint off, heavy can cause underground engineering is flooded, and even building settlement deformation formation of dangerous houses, endangering people's life safety. In addition, the cost of waterproof engineering generally accounts for about 15% of the total cost of single-storey industrial plant, and half of the house maintenance cost is used for leakage maintenance. Therefore, the construction of waterproof engineering must be standardized, standardized and scientific, to ensure the quality, in order to better play the investment effect of infrastructure.

2, the main cause of leakage problems

(1) The performance and quality of materials

The quality of waterproof engineering depends largely on the performance and quality of waterproof materials. The traditional waterproof layer method is mainly used petroleum asphalt or ma hoof fat bonding paper tire petroleum asphalt felt, generally for two felt three oil five layers. The material has some problems such as low temperature brittle crack, high temperature flow, low tensile strength, easy cracking, aging and so on. Because of the short life, generally about 5 years, and even some of the year on the leakage, so, the performance and quality of the material itself is an important reason for leakage.

(2) Construction quality problems Another important cause of leakage is the poor quality of construction. Such as: Because the base is uneven, so that the waterproof layer water, long-term moisture to make paper tire mildew; Improper selection of materials, such as the label of petroleum asphalt is not selected in accordance with the standard requirements, the formula of ma shoe fat is not even qualified, resulting in low temperature brittle cracking, high temperature flow. The details are not well done is the main reason for the leakage in the operation, especially the drainage outlet, parapet, cornice, telescopic eaves, pipe root, plate joints and other parts of the waterproof structure is not appropriate, aerated concrete roof plate stiffness is not enough to cause the collapse of water and other factors; Construction does not pay attention to the protection of finished products, waterproof layer damage, is another cause of water leakage; Rigid waterproof roofing low permeability label caused by water seepage. About Our Factory: 3) Settlement and deformation Due to uneven stress on the roof or building settlement, structural deformation, or earthquake disaster, tearing the waterproof layer of the roof caused by water leakage. (4) Design problems Poor design is also a factor causing leakage, such as improper leakage. If the roof slope is too small, drainage is not smooth, waterproof structure into leakage.

1. Development and application of new waterproof materials Urban-rural development in building technology reform issued by the said: "to improve the quality of waterproof materials and waterproof coating, high-grade development of waterproofing materials, coatings and sealing waterproof sealing material," > "key development during" new waterproof, fireproof and heat preservation and heat insulation materials, comprehensive application technologies' research and development work, establish and develop product series, the standard and application procedures, The latter decade has generally reached the international level of the 1970s and 1980s." This fully illustrates the urgent requirements for the development and application of new waterproof materials. In recent years, all over the country have actively developed and applied a variety of elastic and plastic, long service life, good technical performance, cold construction, easy operation, low pollution of organic polymer waterproof rolling materials, waterproof coatings, waterproof airtight materials. These materials have good weather resistance, high tensile strength, large elongation, cold operation, convenient construction, wide use temperature range, can reduce environmental pollution and improve construction conditions. At present, the rubber-based new waterproof material in China has accounted for more than 20% of the whole waterproof material, the traditional multi-layer asphalt waterproof felt will gradually narrow the scope of use.
