First, the product description and uses: epoxy coal tar cold tapes from the baseband and styling gels composed of two parts. Baseband polypropylene non-woven mat impregnated with coal tar epoxy adhesive substrate, and then by slitting, rewinding, made from oil, according to the thickness into GH401 strengthen the level (0.4mm), GH402 Special strengthen the level (0.6mm) and GH403 jumbo (0.8mm) are three to cutting width according to user requirements. Styling gels by the repackaging of A, B grouped, divided by temperature (temperature above 0 ℃ to use) normal type, low temperature (0 ℃ --8 ℃ in use) and ultra-low temperature (-5 ℃ --25 ℃ Use) three. Epoxy coal tar cold tapes baseband and styling gels matching supply factory, styling gels A and B were mixed equal amounts of construction, then styling gels / baseband / styling gel structure wrapped around the pipe surface, standing naturally cured the formation of coal tar epoxy coating. Suitable for underground and underwater steel oil, gas, water, heating pipe wall corrosion, but also for waterproof steel tank and cesspool tank bottom, roofing membranes, toilet, bathroom, basement and other concrete structures and anti-leakage. Second, product characteristics 1, epoxy coal tar cold tapes to solvent-free environmentally friendly products, namely baseband and styling gels do not contain any volatile solvents, security, fire protection and the effective protection of the environment and health of construction workers. 2, cold tapes substrate selection polypropylene non-woven carpets, the material is high mechanical strength, good corrosion resistance of new synthetic fibers, and wax-free surface, uniform thickness, so the coating surface roughness, adhesion close, needle hole less, excellent electrical performance and corrosion resistance. 3, styling gel as drying solvent-free formulation, coating curing speed, and according to the season is divided into normal type, low temperature and cryogenic-two, it can be normal construction throughout the year, to ease the winter construction problems. 4, the construction convenient, once wound can be achieved to strengthen the level Chinese oil and gas industry standard SY / T 0447-96 or special requirements to strengthen the level required for coating thickness and spark leak voltage, than the original epoxy coal asphalt paint and glass cloth combined into the same coating provincial workers, convenient and fast. 5 epoxy coal, coal tar epoxy cold tapes so that the construction of coal tar epoxy coating into the factory to the processing system, effectively improving the quality and speed of construction, for such a low price, good long life, corrosion resistance of asphalt fiberglass coating pioneering the use of areas. Third, technical indicators ceramic composite pipe wear tube wear elbow Executive Standard: SY / T0447-96 No. Item Unit Index Remark 1.

Steel surface to remove oil, preferably blasting or sand-blasting to a minimum reach GB / T Sa 8923 level 2, preferably to Sa 2 1/2 level. When conditions are subject to restrictions, may also be used by hand or power tools rust to St 3. After the steel surface treatment eligibility, must be painted as soon as possible before returning rust. Concrete surface should be dry (surface moisture less than 6%), remove loose surface material, showing a flat solid surface. 2, with styling gels. First A and B were, respectively, stir, and then press the Part A: B = 1: 1 (by weight), immediately after mixing. Styling gels using quick-curing agent, curing speed, but the use of shorter, so with a good summer to be spent in 1h, winter should be used within 2h. Now with the current construction should avoid batching barrel in solidification and unusable. Environmental temperature above 5 ℃, the construction should use styling gels at room temperature (should not be used in the following 5 ℃, because painted after curing time is too long, affect the construction schedule), environmental temperature below 5 ℃, should use low temperature setting glue (5 ℃ above can not be used, otherwise the curing speed is too fast, with a good styling gels easily solidified in the barrel can not be used, and the coating surface prone to bubbles, affect the quality). 3, weld playing putty. In case of 2mm bead height above the surface of the pipe and two steel plates overlapping special cases, response seam sides and lap steel playing putty face a smooth transition, to pit the concrete surface should also play putty smooth . Putty made with good styling gels plus about twice the weight of talcum powder and mix thoroughly prepared, should now tone service is used, after a good tune up within 2h. 4, glue and tapes. Epoxy coal tar cold tapes before coating the steel surface must be dry, glue the full amount requested, shall holidays, wrapped baseband immediately after coating, lap width of 20 ~ 25mm, must be tightened to make close contact with the surface is smooth and no drum kits, some glue oozing from an area (or show insufficient amount of glue), wrapped with tape immediately after brushing a layer of hair spray and then evenly. Such as requiring wrapped two baseband, can then reverse again wrapped layer over the surface and then cover hair spray. After the end of the day, can my company matching supply thinner to clean brushing tool, filter out debris after diluent, it can be used again, but it must be airtight storage, and shall not be used to dilute the solvent-free styling gels. 5, leak detection and trapping. After the coating was allowed to stand wrapped drying, for at least 8h, no rain, no flood damage. After the coating of hard work, with spark leak, according to the Chinese oil and gas industry standard SY / T 0447-96 under the leak voltage, namely: to strengthen the level (0.4mm) with 2500V, strengthening of special stage (0.6 mm) with 3000V, strengthening of special grade (0.8mm) 5000V checking a few pinholes or holidays due to uneven coating is formed, and pinholes at the circle with chalk marks and painted hair spray trap as soon as possible. Such as requirements for leak detection coating with higher voltage, plus hard work after the coating layer is coated 1-2 styling gels or coal tar epoxy paint. 6, quality inspection. According to the conditions and methods of SY / T 0447-96 stipulated, the appearance, thickness, and adhesion leak check. V. Notes 1, must be supporting the use of baseband I supply, styling gels (including A, Part B). 2, each box styling gels according to the number of supporting only the normal amount of styling gel / baseband / styling gels standard structure construction. 3, transport should be gently, carton upright to prevent rain, avoid sun exposure. 4, epoxy coal tar cold tapes should be stored in its original packaging and store in a cool, dry, ventilated, no source of ignition near the warehouse, stacked up to four layers, the storage period of six months.
