The technical requirements for waterproof tapes mainly include the following aspects:
Production process: Waterproof tapes usually use polyamide films as the base material, add butyl rubber adhesives and leveling agents, and are made through specific coating and drying processes. The control parameters in the production process directly affect the intrinsic quality and external performance of waterproof tapes.
Performance requirements:
High temperature resistance: It can remain stable under high temperature conditions of 150°C for a long time without softening or deformation.
UV resistance: It can be protected from UV damage in an environment exposed to sunlight and maintain a long service life.
Chemical corrosion resistance: It can withstand corrosion from chemicals such as acids, alkalis, and salts, and maintain a high service life.
Water resistance: It can be used in water for a long time without swelling or peeling.
Adhesion: It has good adhesion and can bond surfaces of different materials.
Application scenarios: Waterproof tape is widely used in construction, electricity, oil and gas, mining and other industries for insulation, sealing and waterproofing of pipes, cables, etc. It has good sealing, long service life and low cost.
How to use:
Ensure that the bonding base is clean and free of oil, gray water and water vapor.
The base temperature must be above 5°C, and special production can be made for specific low temperature environments.
Before construction, the performance indicators of the tape should be carefully read to ensure that it is suitable for the ambient temperature and humidity during construction.
According to different waterproof membranes and construction methods, tapes of different specifications and sizes are selected.
After construction, the waterproof layer needs to be maintained to ensure that the waterproof membrane and the leveling layer are firmly bonded and there is no hollowing phenomenon.
