Contact: Ginger on piano Tel: 18669735308 main purposes: 1, new and old concrete connection: This is the new ideal binder old concrete interface connection, commonly used in construction joints, reinforcement beams, old infrastructure transformation projects. 2, concrete sand from the grassroots repair process: It can be used to repair the concrete surface from the sand, pockmarked face, exposed tendons. 3, the concrete surface protection and moisture treatment: It can be used for surface protection of concrete and steel, to prevent deterioration and corrosion. Or moisture barrier coatings for oil, combined with a solid polyurethane soil. 4, acid corrosion requirements occasions plaster or brick panels and paste construction: It can be used to have acid corrosion engineering requirements for special occasions plaster and brick paving project board, and in the wet subbase. Technical Data Construction Description Primary treatment removed loose parts, sweep or water rushed to the surface from dust, moisture or allow concrete base with a release agent on the template exists, but there is not a lot of clear water or oil accumulation. Glue preparation A: B = 1: 3 (volume ratio) dubbed glue stand. Note: 1, A and B reclaimer container used separately, each ingredient should not be too much, with the distribution with the use of glue. Used within 2-3 hours. 2, during storage A and B were not mixed. 3, if there is water, precipitation, stir well after use does not affect performance. A construction process, the construction of new and old concrete connection a mortar configuration: According to J-302 mixed glue: water: cement: sand - = 1: 4 ratio were mixing: 1: 3. 2, primary nap: with a brush or broom and other tools to the stirred mixing glue mortar thrown brush on the base, pull into the rough surface can be carried out after hardening plaster construction. 3, the reference amount: about 0.3 kg / square meter. Second, the concrete sand from primary treatment: 1, mortar configuration: According to J-302 mixed glue: cement: sand - = 1: 1-2 were mixing: 1-2. 2, after the ground has been cleared off or loose dirt, diluted 1-2 times J-302 glue mixed with water, brushing sand from the grass roots, so to maximize the penetration of glue into the grassroots. 3, after the configured site mixing mortar sand from scratch in 1-2 times, sprinkle cement calender. 4, according to the normal plastering construction conservation. 5, the reference amount: each process with about 0.2 kg / m, the different layer thicknesses vary the amount of repair. Third, the concrete surface protection and moisture treatment: 1, mortar configuration: According to J-302 mixed glue: cement: sand = 1: 1-2: 1-2 mixing proportions. 2, the mixed mortar configuration evenly brushing the grass-roots level, first with relatively little lean mortar mix, the second, three mortar mix use a little thick. Each process should be more than four hours interval. 3, general brushing two concrete protection required, waterproof treatment should be brushing two to three. 4. Dosage: each process with about 0.2 kg / m, different amount of thickness change. Fourth, there are occasions acid corrosion requirements plaster or brick slab construction Paste: 1, mortar configuration: According to J-302 mixed glue: water: cement: sand - = 1: 1: 2-4: 4-6 proportions were mixed and stirred. 2, using the configuration in accordance with normal good mix mortar or plaster ceramic tiles paving construction methods and requirements for construction can be. 3, the reference amount: The combined thickness of 3-4mm computing, J-302 glue mixed with about 0.5 kg / square meter. 1. Packing transport packaging deposit: 15 + 45kg / groups. 2. stored at 5 ℃ cool dry place, avoid the sun, rain, shelf life of six months. 3. Non-toxic, odorless, non-flammable, non-explosive, according to general cargo transport.
