Product Description:

1.Structure of  PVC Waterproofing Membrane Description:

Uniformity of polyvinyl chloride (PVC) waterproofing membrane is a kind of excellent high quality, high polymer waterproof material, PVC resin as the main raw material. The PVC resin and plasticizer, anti-uv agent, anti-aging agent, stabilizer, processing AIDS, molding of polymer waterproof coiled material is manufactured by extrusion method. The use of advanced equipment and advanced technology production made. This product with unique product formulations, waterproof materials, product life far beyond the general product has high tensile strength, elongation, shrinkage of small, low temperature flexibility and long life of the waterproof system, roof for more than 20 years, underground for more than 50 years, has been widely used in architecture, civil engineering, to adapt to the roofing construction ,underground engineering ,tunnel engineering and the application of special occasions, the product performance is stable, reliable quality, convenient construction.

2.Main Features of PVC Waterproofing Membrane:

Long service life, resistant to ageing

Q:What is the meaning of "channel" and "layer" in the practice of polymer waterproofing membrane?
In addition, the two did not meet the required thickness of the waterproof layer, according to certain requirements for laminated composite, two waterproof layer can be considered a waterproof. Such as 1.2mm polyurethane + 1.2mm self-adhesive coil (laminated construction rather than separate), can be used as a waterproof, although with two kinds of materials to do a two-story waterproof, and can not be considered two waterproof. The thickness of the laminated composite waterproofing layer can be thinned, and its provisions may be reflected in the new "roofing engineering technical specification" to be published.
Q:What is the preferred level of waterproofing?
3, roof 3 waterproof: Application: general building; Waterproof layer of reasonable use of life: 10 years; Waterproof layer selection of materials: should choose three asphalt four oil asphalt waterproofing membrane, polymer modified asphalt waterproofing membrane, synthetic polymer waterproofing membrane, metal sheet, polymer modified asphalt waterproof coating, synthetic polymer waterproof coating , Fine stone concrete, flat tile, felt tile and other materials;
Q:What are the advantages and disadvantages of waterproofing membrane?
The advantages of the membrane waterproof, such as: the construction is convenient, the construction period is short, not need to be cured after forming, is not affected by the temperature, the environmental pollution is small, the layer thickness is easy to hold and hold the fortification meter, the material is calculated accurately, the site management is convenient, jerry, a uniform layer thickness, the base layer can effectively overcome stress empty shop (the base layer occurs at the time maintaining the overall efficiency of large cracks waterproof layer).
Q:What are the requirements for the storage of waterproofing membranes?
Prohibited sun exposure, exposure easily deformed.
Q:What is the material on the insulation layer on the waterproofing membrane?
The isolation layer of the roof waterproof layer is generally set between the waterproof layer and the above rigid protective layer, and he has two roles. 1, the surface of the rigid layer (usually 40mm thick fine stone concrete) will have thermal expansion and contraction deformation, if the waterproof layer and the rigid layer is very good, rigid layer deformation will affect the deformation of the waterproof layer, so there may be waterproof Layer to produce a direct cracking or long-term fatigue damage, so the two tectonic layers should be set with a sliding function of the isolation layer;
Q:What is the difference between PET waterproofing membrane and BAC waterproofing membrane? What is the commonality? Is BAC a PET?
BAC is not equal to PET, carcass material is not the same, and BAC also fiberglass tire coil.
Q:Why the roof of the waterproof membrane and insulation rock wool board to do between the isolation layer?
Roof on the waterproof membrane and the insulation between the rock wool board to do isolation reasons: 1, leveling layer is generally in order to make waterproof sheet paving when the formation is not empty drums, and sometimes leveling layer can also increase the bond strength of the substrate and the grassroots. But not all of the membrane paving must be done leveling layer, such as polyethylene polypropylene waterproofing membrane is a special mortar as a binder, not very uneven in the base can be directly on the construction. The insulation layer of the grassroots level is generally not leveling layer, but do nothing bad, to reduce the block insulation material porosity, improve the insulation effect and the overall strength of the insulation layer is useful.
Q:APP selection of asphalt waterproofing membrane selection points
3, Ⅱ type fiberglass fetal APP modified asphalt waterproofing membrane tension is higher, dimensional stability and heat resistance, good, but no elongation. Suitable for general and relatively cold areas and stable structure of the general engineering roof or underground waterproofing works.
Q:Waterproof membrane in the escape when the full shop, empty shop, shop, shop what is the difference?
3, point shop paving the membrane, the membrane and the base layer with point-like bonding. Requires no less than five points per square meter of bonding. Each paste area of 100mm * 100mm. Between the point and the point should be equidistant plum-like distribution (the method can be used at the grass-roots level coating, coiling point of the membrane point coincidence).
Q:What is rigid waterproof, flexible waterproof?
2, flexible waterproofing refers to the waterproof layer in the external force, the waterproof material itself has a certain degree of stretch ductility (such as rubber-like flexibility), to resist the elastic layer of elasticity within the grassroots cracking, showing a certain degree of flexibility. Such as rubber-like membrane waterproof, polyurethane coating waterproof.
