Polyethylene polyester waterproof rolling material

Operation procedure of polyethylene polypropylene waterproof roll

Acceptance and cleaning of base course (leveling layer) g preparation of adhesive (preparation with use) g treatment of complex parts (internal and external corners, cornice, outfall, pipe hole and other parts) additional layer g application of ﹖ I waterproof layer g inspection of waterproof layer g construction acceptance of protective layer.

Construction and operation requirements of polyethylene polypropylene waterproof roll

(1) the base course surface (leveling layer) for paving waterproof roll must be cleaned and watered to ensure the base course is wet (Note: the waterproof leveling layer of the roof shall meet the requirements of

Gb50207-94 technical code for roof engineering stipulates that the underground waterproof leveling layer shall comply with gbj208-83 code for construction and acceptance of underground waterproof Engineering).

(2) polyvinyl alcohol glue (107 glue or 801 glue) containing 10% - 15% of cement weight is used to prepare cement paste binder. The mixture must be uniform without precipitation, clot or segregation.

(3) before the construction of the main waterproof layer of the roof, the detailed nodes with centralized drainage and complex structure shall be sealed and the additional layer shall be pasted, and the coiled material used for the additional layer shall be the same as that of the main waterproof layer.

(4) the sealing material is polyether polyurethane. If other sealing materials are selected, they shall be free of mineral oil, earth forest and other chemicals that affect the performance of polyethylene.

(5) additional layer shall be laid at the corner, and the internal and external corners shall be made into R = 20mm arc shape.

(6) the waterproof roll shall be paved with full paving method, and the adhesive shall be brushed evenly on the base course surface without exposing the bottom or piling up; after the adhesive is brushed, the roll shall be paved immediately to prevent the long time from affecting the bonding quality.

(7) the waterproof coiled material shall not be folded or stretched. The air and excess adhesive under the coiled material shall be removed while paving, so as to ensure the dense bonding between the coiled material and the base course surface as well as between each layer of coiled material.

(8) the overlapping width of the waterproof roll shall not be less than 100mm.

(9) the joints between the upper and lower layers and the adjacent two sheets of coiled material shall be staggered by one third of the width.

Xtsbc-120 series polyethylene polypropylene composite waterproof roll is a new type of waterproof material composed of polyethylene synthetic polymer as main waterproof layer, additive, anti-aging layer, reinforced tackifier and polypropylene non-woven fabric through automatic production line.

Characteristic:

The upper and lower surfaces of the product are rough, and the non-woven fiber has an irregular cross structure, forming a three-dimensional mesh. It is suitable for a variety of materials to be bonded, especially directly with cement materials in the solidification process. It can be constructed as long as there is no open water. It has good comprehensive performance, high tensile strength, strong impermeability, good low temperature flexibility, small expansion coefficient, easy to bond, and large friction coefficient, which can be directly used in sand, with stable and reliable performance. Is a non-toxic, pollution-free green environmental protection products.

The product is suitable for roof waterproofing, ground waterproofing, moisture-proof and air separation of industrial and civil buildings, indoor wall and ground moisture-proof, toilet waterproofing, water reservoir, channel, bridge and culvert waterproofing, anti-seepage, metallurgical and chemical anti pollution and other waterproofing.
