Polyethylene high polymer polypropylene (polyester) waterproof coil

Product information: Product features

The upper and lower surfaces of the product are rough, non-woven fibers are irregular cross structure, forming three-dimensional mesh, suitable for a variety of materials bonding, especially with cement materials in the solidification process directly bonding, as long as there is no water can be constructed, its comprehensive performance is good, high tensile strength, strong permeability resistance, low temperature flexibility, small expansion coefficient, easy bonding, small friction coefficient can be used directly in sand. Stable and reliable performance.

The product is suitable for industrial and civil building roof waterproof, ground waterproof, heart tide gas insulation, indoor wall ground moisture, toilet waterproof, water pool, channel, bridge and culvert waterproof, anti-seepage, metallurgy and chemical pollution and other waterproof.

When the thickness of the main material of the composite sheet with fabric reinforcement is less than 0.8mm, the elongation of the rubber break is not checked, and the performance is allowed to reach more than 80% of the specified performance when the thickness is less than 0.8mm.

Operating procedure

Acceptance and cleaning base (leveling layer) - preparation of adhesive (preparation as used) - treatment of complex parts (Yin and Yang corners, eaves, water outfall, pipe holes, etc.) Additional layer - construction waterproof layer - waterproof layer inspection - protection layer construction acceptance

Construction operation requirement

(1) The base surface (screed layer) of the coated waterproof sheet shall be cleaned and sprayed with water to ensure that the base layer is warm.(Note: The roof waterproof screed layer shall comply with the provisions of GB50207-94 "Technical Specifications for Roofing Engineering", and the underground waterproof screed layer shall comply with the provisions of GBJ208-83 "Code for Construction and Acceptance of Underground waterproof Engineering").

(2) The cementin slurry binder is prepared with the polyvinyl alcohol adhesive liquid containing 10% to 15% of the cement weight, and the mixing must be uniform, without precipitation, no clots, and no segregation phenomenon.

(3) Before the construction of the main waterproof layer of the roof, the detailed sections with concentrated drainage and complex structure should be sealed first, and the coil used in the additional layer is the same as the coil material of the main waterproof layer.

(4) The sealing material is polyether polyurethane. If other sealing materials are selected, they should not contain mineral oil, petroleum jelly and other chemicals that affect the performance of polyethylene.

(5) Additional layer should be added to the corner; The Angle of Yin and Yang are made into R=20mm circular arc.

(6) The waterproof coil should be applied with full paving method, and the adhesive should be applied evenly on the base surface, without exposing the bottom and without accumulation; The adhesive should be immediately laid after brushing, to prevent too long to affect the bond quality.

(7) The waterproof sheet shall not be wrinkled, shall not be forced to stretch the sheet, and the air and excess adhesive under the sheet shall be excluded by the side of the sheet to ensure that the sheet and the base surface as well as the bond between the layers of the sheet is dense.

(8) The lap width of the waterproof coil shall not be less than 100mm.

(9) The joints of the upper and lower two layers and the adjacent two sheets of coil should be staggered by one-third of the amplitude.
