Waterproofing materials

Product Overview: SKB-302 is a flexible composite waterproof material waterproof material Co., Ltd. Shanghai Infiltration grams developed, produced three General Staff Corps of Engineers, Water Technology Centre for People's Liberation Army National Defense projects recommended for national defense projects for the special waterproof material. It is a high performance polymer cement as the main membrane material and add permeable crystalline active materials and other additives formulated, and inorganic and organic composite materials have the dual advantages of rigid-flexible combination of Multiple Protective, waterproof performance is extremely excellent, is ideal for all kinds of waterproofing. Is the green environmental protection building materials. Features:1, SKB-302-type flexible composite waterproof material can be adapted to different project types and water requirements in different environments;2, the construction method is simple, you can wet the grass-roots, on a much shorter period; of mortar concrete surface produce the desired penetration depth.3, the strong bonding, without hollowing, seamless, roll-style form of tight seamless whole cover, waterproof, moisture-proof, excellent impermeability of the mortar produces a permanent waterproof concrete matrix.4, on the bar and no corrosion of metal materials to improve concrete strength, to prevent chemical corrosion, freeze-thaw damage of concrete and steel corrosion.5 non-toxic, harmless, non-polluting the environment and health-based materials. Crystals with high temperature, ultraviolet radiation and oxidation characteristics of the outside world.6, the core product is cement based and high-permeability type, inorganic and organic composite materials with the dual advantage of good permeability, semi-rigid semi-flexible, rigid-flexible combination of Multiple Protective, waterproof best performance, convenient and simple construction. Flexible life up to 15-30 years, 30-50 years not rigid up to repair and maintain life long, once and for all, which saves maintenance costs later. Water as dispersing agent, non-volatile organic solvents, are environmentally friendly products.7, high temperature (50-60 °C) and low temperature (-20-0 °C) no change in performance materials, anti-UV and anti-tensile strength, elongation at break inflation rate reached an excellent standard; treatment does not affect the base level after the second construction.Scope:SKB-302 can be used in the basement, roof, interior and exterior walls, bathrooms, swimming pools, dams, power plants, bridge tunnel, indoor and outdoor water tanks, suitable for plugging of all water projects, it is non-toxic, flammable, can be widely applied in a variety of water projects. Can be directly used for tile and other decorative wall plate and cement bonded materials, both from the water effect, but also beautiful.Usage:1, primary treatment: examination situation of the grassroots, scrape or clean cement mortar, concrete surface of the oil, releasing agent, dust, various paints, organic film, painting surface, until the cement grassroots clean, there are obvious cracks along the crack digged wide 25mm, depth 30mm 50mm of the "V" groove. Then add 2% content of cement, SKB-302 mixed into cement paste, smoothing filled "V" groove. Have clear water (Chung) phenomenon, should be plugging, and then waterproofing.2, waterproof construction: the vertical and horizontal to the base surface using water jet cleaning, to be grass-roots and dry the surface after the Group A points evenly spray, brush dipped in Group A can also be divided evenly wool brushing the surface of the grass roots to require spraying or in multiple Brushing at the grassroots level inhalation of Group A points per square meter up to 1 kg, completely dry before the Group B Group C sub-divided and measured by weight ratio of 2:3 to take material, material group were poured into the liquid inside the mixing bucket electric drill with a slow (about 400 r / min) stirring, while slowly adding the powder component matching, mixing for about 5 minutes until obtain a homogeneous mixture, (the best place for 10 minutes after the preparation of a good mixture stand as soon as possible 2 hours used), with a brush or roller construction, each construction of a width of 120cm-200cm; elevation of Use spatula and scraper construction; on where the cracks more easily, increased matrix material can be laid. In the ideal basic conditions, 1mm thick coating theory of dosage 2.1kg/m2; waterproof coating over the coating to be delaminating.Note: prohibit the construction of below 5 °C or rain, do not especially humid environment without ventilation, and construction under the hot sun, otherwise the impact of film; outer protective layer decoration layer should be waterproof coating cures completely before construction, specific requirements See GB 50207-2002 "Quality Acceptance of Roof Engineering" and GB 50108-2001 "underground waterproof technical specifications" relevant chapters.Packaging, storage: 1, A: fluid materials, plastic buckets, 5 kg / drum, 20 kg / barrelB: powder, laminating bag, 5 kg / bag, 20 kg / bagC: liquid material, plastic buckets, 5kg / drum, 20kg / barrel.2, Storage: This product should be kept in ventilated and dry place sealed to prevent direct sunlight. Shelf life of 10 months.
