Asphalt-based waterproofing membranes

Asphalt waterproofing membranes include: elastomer (SBS) modified asphalt waterproofing membranes, plastic body (APP) modified asphalt waterproofing membranes, asphalt Composite tire flexible waterproof membrane.

Elastomer (SBS) modified asphalt waterproofing membrane, plastic body (APP) modified asphalt waterproofing membrane are based on polyester tires or fiberglass tires, and asphalt composite tire flexible waterproofing membranes It is based on asphalt, and most of the composite tires used are made of chemical fiber rags and high-alkali fiberglass mesh cloth. They have poor mechanical properties, mold resistance, water resistance, and durability, so they have a short service life. They are mainly used for Some temporary buildings or situations where the fortification level is not high.

So how should you choose the above three materials?

1. Packaging labeling

From the appearance point of view, there is not much difference between the above three materials, so you must first check whether the packaging and labeling are standardized. The mark must indicate: manufacturer name, trademark, product label, production date or batch number, production license number, storage and transportation precautions, all are indispensable. Each roll of coiled material should be marked and marked in strict accordance with the order specified by national standards. At the same time, it should be noted that the storage period of coiled materials is generally not more than one year.

2. Look at the tire base

You can judge whether the tire base is consistent with the mark by tearing the edge of the roll with your hands. Polyester tires are extremely difficult to tear and pull off by hand, and asphalt has a good affinity with the tire base. However, asphalt composite tire rolls are often easy to tear, and the condition of the tire base can be observed after tearing.

3. Judgment through physical performance testing

The physical and mechanical properties of the rolled material cut to 1m?2 shall be tested according to the standard. If it meets the standard requirements, it is a qualified product.

Polymer waterproof membrane

Polyethylene polymer waterproof membrane (polypropylene, polyester): easy to bond, large friction coefficient, wide temperature range, and high tensile strength , strong impermeability and other characteristics. It can be used with a variety of adhesives. There are no special requirements for the base layer. It can be constructed as long as there is no open water. The surface of the waterproof layer can be decorated directly after construction. This product is a non-toxic, non-polluting, green and environmentally friendly product. .

PVC waterproof membrane: long service life, aging resistance, high tensile strength, high elongation, and small dimensional changes during heat treatment. Good low temperature flexibility and good adaptability to temperature changes. It has good puncture resistance, easy construction, strong and reliable during welding, and is environmentally friendly and pollution-free. Resistant to chemical corrosion and suitable for various occasions.

TPO thermoplastic polyolefin waterproof membrane: excellent weather resistance and weldability, good high and low temperature resistance, chemical corrosion resistance, heat aging resistance, good stability, energy saving and environmental protection, high strength, sealing Good, excellent water resistance.
