product description

 

The high-quality long-fiber polyester felt is used as the base material, and the petroleum asphalt is modified by APP (random polypropylene) as a modifier to prepare a rubber layer dip coating material, which is fine sand, mineral pellets and polyethylene film. A plastomer-modified bitumen waterproofing membrane made of a cladding material.

 


 

Features

 

(1) High tensile strength, good tear resistance, good dimensional stability, and strong adaptability to deformation of the base layer.

 

(2) Excellent corrosion resistance, mildew resistance and weather resistance.

 

(3) Excellent puncture resistance, smash resistance and fatigue resistance.

 

(4) Hot-melt construction, the molten asphalt body is lapped, the bonding is reliable, the lap joint is firm, and all seasons are suitable.

 

(5) Excellent high temperature resistance, high temperature resistance of 130 ° C, or even higher.

Scope of application

 

It is suitable for waterproofing of road and bridge waterproofing and high temperature industrial factory houses with special requirements for high temperature, or for waterproofing of exposed roofs of buildings in high temperature areas in the south.

The waterproof layer is exposed with slate cladding; the protective layer is non-exposed waterproof layer using fine sand or vinyl film cladding

 


 

Construction process

 

Grassroots requirements

 

The base layer is dry and solid, free of sediment, garbage, no empty drums, loose, sanding.

 

Coating treatment agent

 

Spray or roll the matching base treatment agent to the base layer to ensure that the base treatment agent is uniform and full of the base layer.

 

Trial roll

 

The coil material is spread out on the base surface, and the elastic wire or the overlapping edge of the adjacent coil material is aligned to ensure the overlapping width, and the stress is released after being released.

 

Hot melt paving

 

The flame is baked on the lower surface and the base surface of the coil, and the gel melts and rolls the coil in time, and is compacted and exhausted, so that the coil and the base surface are closely adhered.

 

Lap processing

 

At the same time of hot-melt laying, press the lap joint with a pressure roller to extrude 5~8mm molten asphalt (considered as reliable lap joint).
