Yiwu plugging Trapping Office Jiangsu new large plugging Engineering Co., waterproof plugging plugging grouting material: water-soluble polyurethane, the material is a one-component grouting material, and water has a good compatibility, slurry itself dispersed water emulsion slurry of free isocyanate root with the water polymerization, bulk polymerization after consolidation has good extensibility, flexibility and impermeability, in the water to keep permanent prototype, and are resistant to low temperature resistance, foaming expansion, the foam volume after the slurry water can be increased 2-fold (expansion ratio can be adjusted by the formulation), thereby clogging waterways, achieve sealing effect. Waterborne polyurethane is internationally recognized as the new high-quality waterproof materials, and is widely plugging sealing material in the domestic underground project, close to good effect. Polymer grouting material - grouting plugging Wang: Wang is by plugging grouting acid esters with different water-soluble polyether as the main base of chemical additives added a new polymer made of polymer chemistry synthesis grouting waterproof material to form a polymer compound end group containing excessive free NCO radicals, the latter part of the king injected with grouting plugging leaks, leaking water as a crosslinking agent to immediately undergo a chemical reaction and emit CO2, against the current And on diffusion, but also with the surrounding sand, stone, clay, etc. to form an elastic solid body of consolidation, ultimately sealing water plugging sealing purposes. Just combine soft waterproof plugging waterproof plugging process: waterproof plugging process procedures for: fight hair, cutting, tick groove; butted, caulking, plastering, grouting. 2.1 chiseling, slotted, tick groove cutting hair; both sides of the tube sheet joints, each width 20cm, chisels chop with artificial hair, revealing fresh concrete surface and make it rough, good adhesion to enhance the rigidity of plaster and concrete basis. Slotted, tick slot; diamond saw with Nissan concrete cutting machine, cutting width 4-5cm, Goushen 5-6cm, then tick slot impact drill, electric shovels and manual fine last Xiu 5 ~ 6cm deep trench . 2.2 φ14mmPVC hose for pumping tube with mold, double-quick cement or other fast-setting cement pressure pipe Sealing, was evacuated tube operation, finally leaving water grouting pipe. 2.3 caulking material can be used: (1) coal tar epoxy coating (bottom amines and sealant) (2) 851 Tar polyurethane coating (3) TPC polyurethane caulking seal series sealing material; first with a wire brush and brush cleanup out of the trenches and on both sides of floating dust, dirt, and then embed the seam material (construction carried out by a variety of caulking materials, construction techniques), requiring repeated extrusion through dense after filling them, the best caulking material curing process artificial pressed twice to make a better bond. 2.4 Plastering Plastering Plastering waterproof waterproof five practices can implement. Can also be used neoprene polymer mortar surface. After wiping the surface water conservation must complete three to four days. 2.5 Grouting first hand injection pump to lift water pipe pressurized water, and then the slurry pressure injection of water-soluble polyurethane (or other chemical grouting material). After the slurry is cured, cut off with a knife embedded water pipe, and then double-quick cement closed. Jiangsu large molecule nanoparticles grouting waterproof plugging new technology is suitable for the following types of engineering for you: (a) pool water plugging: plugging the pool, cable channel, cable channel plugging, plugging the pool, biochemical pool, acid pools, Shen fixed pool plugging, plugging water pool wine; (b) the dock plugging works: for a variety of cable channel plugging, plugging cesspools, caisson plugging plugging, underpasses, arising from leaking underground civil air defense projects plugging plugging leakage repair, clogged method commonly used methods, grouting, plastering method, roll coating process, etc. (c) Pressure Seal engineering: the company's patented technology pipes, flanges do not stop with pressure sealing, bonding top pressure pipeline, flange Pressure Seal. Online no lockout valve Pressure Seal technology, up and down the connection plugging, plugging stem packing box, petrol storage cabinets without offloading plugging. (Iv) expansion joint sealing: Professional to undertake a variety of bridge expansion joints, pool joints, construction joints, construction joints, cross joints, cracks off, settlement plugging leakage of water. (Five) tunnel plugging project: to undertake a variety of highway tunnels, subway tunnels, railway tunnels, mountain tunnels, tunnel, cold regions tunnel, karst tunnels, subway channel plugging, plugging immersed tube tunnel project (six ) underground tunnel, caisson plugging: Professional undertake underground hydropower tunnel plugging, pump plugging, cesspool plugging, plugging the cable channel, culvert plugging, plugging caisson. (Seven) basement plugging: specializes in all kinds of coal, iron ore basement plugging wellbore plugging, plugging the roadway. (Eight) cable channel, cable channel plugging: Professional to undertake a variety of wire and cable trenches, substation cable trench plugging, plugging the cable trench Zhenjiang, Zhenjiang cable channel waterproof plugging maintenance cesspool plugging, plugging plugging caisson Zhenjiang Drain Project. (Nine) coal corridor plugging: to undertake professional glass, power plants, steel plants and other coal corridor plugging. Yiwu plugging Trapping Office
