4mm Sbs Modified Asphalt Roofing Membrane For Undergroud

Building Construction Hot Melted 4mm Sbs Modified Asphalt Roofing Membrane For Undergroud

Asphalt roofing membrane introduction:

SBS elastomer modified asphalt waterproofing membrane is made of SBS rubber modified petroleum asphalt as infiltration coating layer, polyester fiber non-woven fabric, jute cloth, glass fiber felt, etc. are respectively made into tire base, and plastic film is used for anti-adhesion. The separation layer is processed by the steps of material selection, compounding, eutectic, infiltration, composite molding, and curling.

Asphalt roofing membrane characteristics:

a) SBS modified bitumen water proofing membrane is specially used as waterproof material in cold area
b) APP is specially suitable for areas of high temperature and of strong sun-shine SBS/APP Modified Bitumen Water proofing Membrane
c)Good performance in Good impermeability ,anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering
d)Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack

Asphalt roofing membrane advantage:

1. Strong water impermeability.
2.High tensile strength, high elongation, strong adaptability to base layer shrinkage deformation and cracking.
3.Good low temperature performance, can maintain efficacy at -50 °C, suitable for hot and cold areas, especially in cold regions.
4.Puncture resistance, smash resistance, tear resistance.
5. Corrosion and mildew resistance. Good weather resistance.
6.Convenient construction, hot melt method can be operated in all seasons, and the joints are reliable.

Asphalt roofing membrane applying method:

1, brushing base treatment agent (same cold construction method)
2. The coil is placed at a predetermined position, and the base layer and the bottom surface of the coil are heated by a liquefied gas or a gas oil blower. After the surface asphalt is melted by a thin layer, the coil is rolled forward while being baked, and compacted by a press roll. Adjust the size of the flame, melt the asphalt on the surface of the coil, do not flow too much, and can not be baked.
3, the coil is overlapped in the vertical and horizontal directions of 10CM, and sealed with a blowtorch.
4, double waterproof, coil joints must be staggered according to regulations.
5, the thickness of the coil is less than 3 mm or the cladding material is aluminum film is not suitable for hot melt construction.
