1.Clean the base layer, apply the base treatment agent, reinforce the node, position the elastic line, lay the self-adhesive waterproof membrane, fill the joint, and hand over the working face.
2.Detailed method of laying the coil: open the whole coil, insert a steel pipe into the paper core tube in the center of the coil, and then lift it to the starting end to be laid by two people, exposing another 500mm coil forward. The man strips the separator paper from the secondary coil and rolls it onto a core tube made of used wrapping paper. Place the stripped stripping roll on an elastic base and press it tightly.
Self-adhesive waterproofing membrane is a common phenomenon in summer, which seriously affects the production progress and construction progress. So what are the factors that make self-adhesive products difficult to remove in the summer?
There are three main points to introduce waterproof coating manufacturers:
1.When the coil is produced, the discharge temperature exceeds the withstand temperature of the separator film. In the production process, the discharge temperature of various products is different. In the absence of cooling equipment, it is difficult for some small manufacturers to achieve the required discharge temperature. As long as the separator does not shrink and its production process has not been heated, the roll separator is difficult to isolate, and the separator film will wrinkle, which will seriously affect the appearance of the product.
2.The resulting coil cannot be cooled in time. After the coil comes out of the oiler, it needs multiple cooling water to cool it flexibly. However, sometimes the cooling water is too high and cannot cool the surface of the coil in time, resulting in the coil being in a high temperature state for a long time and unable to open the film.
3.Due to the temperature during construction in summer, it is difficult to uncover. In summer, when the outside temperature is high, the endothermic index of the coil itself is high. If the membrane is exposed to sunlight on the construction site, the surface temperature of the membrane will reach 40°C – and at 50°C, the film will not open easily.
In addition, during the construction process, it is sometimes necessary to lay the membrane on the concrete. After sun exposure and concrete surface temperature, the surface temperature of the membrane can reach 60-70 during construction. However, some places have poor storage conditions, and if the coils are left in the sun, they can easily tilt due to high temperatures.
