Supply EVA tunnel waterproof board lowest ex-factory sales

Sales Phone: 15865930678 Address: Shandong Lingxian Dezhou Economic Development Zone Industrial Park, Edison EVA waterproof board Product Overview: production processes Shandong Edison EVA waterproof board uses advanced single stack of two co-extruded rod extrusion production from the raw material resin EVA join enhancers, antioxidants, melted by heating, plastics, extrusion molding, sheet forming the rear tractor can also be put on tape and geotextiles (signal layer) Thermal integrally formed composite waterproof plate, extrusion rolling method may also be used, about to melt plastics resin extruder, extruded from a slit die head molten sheet blanks and tape integration, cooled by rolling into a film roll, or wear geotextile good sling integration, through the cooling calender roll into a composite waterproof sheet. Features: ※ chemical resistance, resistance to ultraviolet radiation; ※ anti-aging, wear resistance; ※ strong puncture resistance; ※ construction is simple, non-polluting; range: the new railway, highway, municipal roads, light rail construction (including seepage and corrosion-resistant liner deck tunnel), roofing, waterproofing underground works, water conservancy construction, sewage treatment works, landfill engineering, chemical acid treatment ponds and other environmental projects to use. Product Family: Separated waterproof board: geotextiles and tape laying waterproof board stratification. Geotextile composite waterproof board as a whole, point, of the composite, the products left edge seam stitching, and with tape on geotextile can be laid at the whole scene, one time. Specifications: Polyester geotextile: 300-400g / m2 PE / EVA / ECB / ECD synthetic resin sheet thickness: 0.8,1.0,1.2,1.5,2.0mm Width: 2m-6m; construction elements: base surface treatment : waterproof board before construction of the tunnel were measured clearance checks on underbreak lots, uneven, etc. bolt head exposed base surface is treated to meet clearance and base surface. Hanging wire: First tunnel vault marked with red paint centerline, the center line of the dome hanging wire laid longitudinally along the tunnel, and then laying wire from the dome side wall to duplicitous side, spacing 0.9m (less than sling spacing 10cm), and parallel to the tunnel center line, wire ends of a length greater than waterproof laid laying length 1m. When laying wire, the first supporting surface in early stages, with percussion drill, wedge after wedge. The outer end of the wedge wedged flush perforations. After the nails to wedge, the wire hanging on a nail, the nail bending, to prevent puncture when lining concrete nails waterproof board waterproof board and affect results. Nails per 2m a layout, when the tunnel contour irregularities, appropriate encryption, to ensure that wire and Initial Support snug. Hanging waterproof board: the center line of waterproof board is aligned tunnel vault center, the center line of the ropes tied to the tunnel crown center rail line, lateral sling hanging from the dome to the side walls on both sides. After all hung, push the carriage moves forward. Hanging with the law a second ring, third ring, as well as the lining of a loop segment all hanging off. Waterproof board to advance the shop to hang, that is, each cycle waterproof lining plate shop hanging lining length longer than the length of at least 1m, so that large water board firmly bonded joints. Waterproof board Joint Bonding: waterproof plate with adhesive lap, lap length of 10cm. When the adhesive, waterproof board first clean dry joints, then brush evenly with a row of brush on adhesive. When gluing, brushing glue on the paste should not be too thick. Hand-hot, the water board flat on the board, with the scroll wheel car rolling joints, to bond firmly smooth so far. After complete hop-bonded joints, the joints to stay with a wooden top, wait 30 minutes after Remove the top support. Waterproof protection board: When welding steel around it blocked with asbestos cement board, so as not to spark burn waterproof layer. Timely infusion of concrete protection, the secondary lining, a protective layer is on the concrete delivery pipe at the mouth of the water board, water board to avoid damage.
