1. Product Overview
<#>
Chlorinated polyethylene rubber blend waterproofing membrane is made of chlorinated polyethylene Vinyl resin and synthetic rubber are blended as the main body, adding appropriate amounts of accelerators, stabilizers, softeners and fillers, etc., and are processed through processes such as mastication, mixing, filtration, calendering (or extrusion), inspection, rolling, and packaging. Made of highly elastic waterproof membrane. This waterproof membrane has the characteristics of both plastic and rubber. It not only has the unique high strength and excellent ozone resistance and aging resistance of chlorinated polyethylene, but also has the high elasticity, high elongation and good low temperature flexibility of rubber-like materials. . This kind of blended modified material of synthetic polymer is called polymer alloy in industry.
<#> 2. Scope of application
<#> This product is suitable for waterproofing and moisture-proofing on roofs, basements, tunnels, caves, reservoirs, pools, sewage treatment, drainage channels, floors, bathrooms, toilets, etc. . It is especially suitable for waterproofing and roofing projects with high waterproofing requirements.
<#> 3. Construction method
<#>
Check the roof according to the design drawing to see if there are any discrepancies with the design. If there are any discrepancies, they should be reported to the competent department in a timely manner.
<#>
The content of the construction organization design includes: determining the paving positions of trench lines and water dividing lines, arranging node drawings for each special location, work progress plan and construction quality standards.
<#>
Thoroughly and comprehensively clean the roof and never allow sand, soil and gravel to be present. This work is carried out throughout the entire construction process.
<#>
According to the construction design, pop up the gutter center and water separation center line on the roof. Before paving a large area, check special parts such as gutters, eaves, parapets, vertical walls, and water drops. Apply waterproof coating or add an additional layer (reinforcement belt) to the corners of the entrance, pipes and equipment that protrude from the roof, and the yin and yang corners. Fill the seams with sealing material and add an additional layer.
<#>
, Pop up the reference line of the first paving membrane and pop up the sticking lines of the remaining membranes from the downhill to the uphill direction.
<#>
Align one side of the roll with the first reference line and naturally relax the roll.
<#>
Fold the roll in half from the long side and apply adhesive on the roll and base layer according to the determined pasting method. The adhesive should be rolled evenly.
<#>
The adhesive must be initially set before it can be pasted. The inspection method is to touch it with your hands and feel that it is not sticky.
After completion, you must roll it back and forth with a large iron bar or use a hard nylon brush to remove the residual air to make the surface of the roll smooth and solid.
<#>
After the first strip is pasted, pop up the overlapping line on top according to the overlap width and release the second roll of roll material. Press the
method to lay it uphill at the overlap. It is also necessary to use a small pressure roller to roll back and forth.
<#>
There should be no long-side overlapping lines in the center of the gutter and the watershed line. Finally, a roll of membrane should be mounted with the watershed line as the center.
<#>
When paving the roll material, special parts must be properly cut and pasted. Finally, a layer must be added to these parts.
<#>
Use sealant to seal all overlapping seams.
<#>
If a protective layer needs to be added according to the design, the protective layer must be constructed. Some waterproof mortar must be applied to the facade pasting points of some flood basins to ensure the long-term reliability of the waterproof layer.
<#> 4. Precautions for use
<#>
Check the quality of the base layer and if it does not meet the requirements, immediately rework and repair it, and understand the construction date and at least guarantee it
~ d
Construction can only be carried out after the deformation is stable, otherwise do not rush to construction.
<#>
Inspect the treatment of special parts at the base layer, such as the base layer and special parts of the protruding roof (parapets, vertical walls, window walls, deformation joints, chimneys, pipes) and the corners of the base layer (water falls) Mouths, cornices, gutters, gutters, roof ridges, etc.) should be plastered into an arc shape and it is understood that the construction date must at least ensure that the deformation is stable before construction can be carried out.
<#>
Before paving a large area of membrane, the above-mentioned special parts should be processed first. Generally, a layer must be pasted
~
A wide additional layer (reinforcement belt) is required in some parts. For example, gutters and gutters can also be painted with a layer of waterproof paint.
The lap joints connecting vertical roof ridges should be lapped in the direction of the wind with the highest frequency in the year.
<#>
The roll material can be pasted by the full pasting method, the empty laying method, the point pasting method, or the strip pasting method. Which method to use depends on the function and characteristics of the building. In addition, some of the above pasting methods may need to be used on some special parts of the entire roof. In principle, roofs with large vibrations and large deformations can use empty paving and strip bonding. Some local special parts must also use full bonding, spot bonding and Methods such as empty paving can be used first for some roofing membranes that are to be laid with a rigid protective layer such as fine stone concrete or paving tiles.
<#>
In order to give full play to the durability of the polymer coil, a protective layer should be used as much as possible. If the protective layer is not on the roof, spray coating and other flexible protection methods can be used. If it is on the roof, it can be used. Then use rigid protection methods such as fine stone concrete or facing bricks, and an isolation layer must be added between the rigid protective layer and the waterproof layer to protect the membrane from damage.
<#>
The construction of the waterproof layer is the last construction of the roof. It is strictly prohibited to construct other processes at the same time or cross the roof.
<#>
Construction workers should wear soft-soled shoes without nails for construction.
< --d ---d --d ---dd ! Comparison with related products
--d ---dd ! This type of membrane belongs to rubber-plastic blending synthetic polymers The waterproof membrane combines the excellent mechanical properties and aging resistance of chlorinated polyethylene with the high elasticity of rubber. Except for the dimensional stability (heating shrinkage) which is not as good as that of EPDM waterproofing membrane, other material properties are equivalent to EPDM waterproofing membrane.
