PZ type water expansion rubber stop bar 20mm*15mm for construction
The product (PZ) is a kind of new waterproof material which has the
ability of general rubber products and the self-expansion of water.
Water - stopping effect is more reliable than general rubber stop.
-Water pressure, elasticity, resilience are stronger, easy to adapt
to the deformation of the structure, when the building deformation
more than half of the water bar, the product can also absorb water
to stop water.
-Resistant to chemical medium, good durability, free of harmful
substances and pollution-free environment.
PZ encounter water swelling rubber water stop, widely used in civil
building structure distortion seam, construction seam, wear filling
pipeline sealing, shield construction method of reinforced concrete
joint, waterproof seal, interface material pipe jacking
engineering, Ming excavation method of underground pipeline
interface sealing box culvert, water conservancy and hydropower,
channel the place such as civil engineering waterproof seal.
1. the reserved channel: patches of water stop in concrete
construction joint before and after pouring seam sticks on the
interface of the reserved construction groove, groove depth water
thickness of 12 so far, and then fixed by steel studs.
2. Pasting method: brush 401 adhesive tape along the installation
line on a cast concrete face.
3. steel nail fastening method: the steel nails are fixed directly
on the interface, and the steel nail density should be as close as
possible. Should ensure the construction surface level, no sundry,
no water storage before applying the water bar. The horizontal
surface of the horizontal application is 8001000mm, and the time of
the vertical surface is 600800mm. When the connection is made, the
wire can be strapped or pressed together, the length is greater
than 50mm, then the head shall be fixed with steel nails.
Precautions: when transporting and storing, please ensure that the
packaging is intact, avoid direct sunlight, press the weight,
contact water or high water content, high acid base and oil
