Polyethylene closed - cell foam board
First, the physical characteristics
Density: density, high recovery rate, with independent bubble structure.
Water absorption: surface water absorption is low, anti-permeability performance.
Second, the chemical properties
PH: acid, alkali, salt, oil and other organic solvents corrosion, anti-aging performance.
Stability: high temperature does not flow, low temperature does not brittle crack.
Third, the scope of application
Joint expansion joints of soil highway;
Road and bridge joints sealing board;
Water conservancy project embankment, retaining dams, powerhouse, slope protection, retaining wall of the expansion joint plate;
Hydropower, thermal power, engineering, water tower bottom sealing joint plate
Construction settlement joints, frame structure of the caulk board;
Domestic water plant and sewage treatment plant pool sealing sealing plate;
Joints for airport runways;
Ports, docks, concrete joints of the board;
Water tunnel, concrete over the water joint plate;
Subway, underground channel concrete sealing joint plate.
Chemical cross-linked polyethylene foam has its unique advantages, recovery rate, no water absorption, impact resistance, weather resistance, chemical resistance, aging resistance is not the other materials, PE foam Applications more and more widely.
Specifications of the original board
(1600 - 1950) x (800 - 950) x 50 mm,
According to user needs can be any production of 5-50mm thickness of the plate, strip, slice the error in the range of ± 0.2 to ± 1.
6, physical and mechanical properties
0.05-0.14g / ㎡ tensile strength ≥ 0.15Mpa compressive strength ≥ 0.15Mpa tear strength ≥ 4.0N / mm
Heating deformation ≤ 2.0% Water absorption ≥ 0.005g / ㎝ 3 Elongation ≥ 100% Hardness (C-type hardness) 40 - 60 Shore A. degree
Compression set ≤ 3.0%
Closed-cell foam board with high-pressure polyethylene low foaming closed-cell foam board, and sealant interaction material properties unchanged.
7, laying applications
Laying in the concrete to the inside of the first pouring template, the joints should be tight but not to connect the joints should be in the factory according to the structure of the cross-section of the seam is cut, the numbers on the scene for splicing, the use of factory-processed tenon , In order to ensure that the joints are tightly connected.
