Manufacturer of self-adhesive polymer waterproofing membrane: Application and related characteristics of PVC waterproofing membrane
The application scope of PVC waterproofing membrane: basement, tunnel, reservoir, dam, etc.
PVC waterproofing membrane is a type of polyvinyl chloride (PVC) waterproofing membrane, which is a new type of polymer waterproofing membrane made from PVC resin as raw material, adding plasticizers, fillers, antioxidants, UV absorbers and other additives. It has long-term plasticity, stable weather resistance, good sun resistance, heat resistance, and aging resistance, good low-temperature flexibility, self-extinguishing and wear resistance, and the joints are welded by hot air to form a solid and reliable whole, It can be welded for a long time and is convenient for construction. Different construction processes can be selected based on the base surface and construction period.

Self adhesive polymer waterproofing membrane manufacturer: What should be paid attention to during the construction of PVC waterproofing membrane?

1. During construction, pay attention to the construction environment, especially the temperature. Only when the temperature is below -5 degrees can the construction effect be better. When using the plastering method for construction, the temperature of the PVC waterproof material will be controlled above 5 degrees.

During construction, additional layers should be made in special areas.

3. It is also necessary to ensure that the layout is neat and not bent. After the construction is completed, it is necessary to wait for a few days and inspect after the construction is completed to ensure that the construction is qualified.

1. After the base layer is cleaned, waterproof rolls should be applied to the base layer along with the base layer treatment agent, and air dried until it does not stick to hands (feet).

2. Node reinforcement treatment: According to specifications or design requirements, waterproof reinforcement treatment should be carried out on weak waterproof areas such as internal and external corners and detailed nodes.

3. Positioning and pulling: Based on the actual situation on site, arrange the laying sequence and direction of the coil, and pull the reference line according to the requirements of Sara width in the specifications to ensure accurate positioning of the coil.

4. Lay self-adhesive waterproof materials.

5. Overlap of adjacent rolls: Uncover and fold the isolation film according to the overlap width requirements on the rolled roll, and then lay another roll.

6. After laying the cushion layer, inspect the relatively weak parts (such as the end of the coil material, the irregular parts with more coil cutting, etc.). If it is found that the adhesion is not firm, special sealing paste should be used for sealing.

7. After laying, pay attention to ensuring that the isolation film on the surface of the roll is intact and cannot be unfolded too early.
