Features: 1, the old concrete base has good adaptability, strong bonding, density, good water seepage. 2, the protective properties of the steel has been corroded reinforcement can play a protective patch performance, and good durability. 3, to grass roots in wet or humid environment, construction, repairs can be carried out under local conditions do not stop. 4, operating convenience provincial workers, in the intensity of gas corrosive environment, alternative organic coatings, and resin material simple construction and low price. Scope: 1, buildings used for industrial and civilian facilities in reinforced concrete or cracking, panels, load-bearing columns, beams loaded with plaster repair, damp industrial, civil construction of the outer plaster decoration. 2. Patch for cellular concrete, holes and other defects, repair damaged concrete floor and make a thin layer on the concrete, masonry or steel surface overall protective patch surface. 3, for the industry has been damaged and can not meet the design requirements of civil repair. Especially suitable for repairing floors, panels and open sheet structure. 4, for the underground pipeline corrosion requirements, plant dry cooling towers, chimneys, and a variety of chemical structures, plant buildings have maintenance corrosive gases. Use: Primary treatment: 1, surface grassroots demands clean, clean, no oil, no corrosive chemical residues. Surface of the porous materials should be pre-soaked in water, steel base surface rust should be removed. 2, with 901 leaks must first be processed quickly plugging agent, best to keep the base surface moist water subject to ignorance, in order to achieve a better construction effect. Construction and maintenance: 1, with the EC2000 polymer repair mortar as a whole surface layer thickness of not less than 3mm. When a large area of ??construction, should remain a construction joint or slice staggered construction. Each area should not exceed 10-15m2, visual scene environment. Time gap fill joints or slice staggered construction of not less than 24 hours. 2, do the whole surface layer on the surface of the facade and steel concrete or masonry structures, should be carried out twice, each time interval of not less than 24 hours. When the last hand side, should a smooth, not repeatedly wiping pressure. Note: 1, this product construction of the ambient temperature is 10-30 ℃, not less than 5 ℃, the raw material may not be exposed to moisture, rain, sun and debris contamination. 2, the product is not in the rain, when freezing construction. If it is necessary in the winter construction, should take the necessary measures to freeze. 3, with the mix with this product should be used, not too much time spices and spices should be used up within 2-3 hours each time.
