How To Use waterproof tape, precautions for using waterproof tape? | | The waterproof effect of waterproof tape depends on the integrity of the plastic film during the construction and operation process.
Since they are high molecular weight chemical fiber polymers, in order to prevent trampling by humans and animals or damage by animals and plants and avoid direct sunlight, waterproof tape should be supplemented with a corresponding protective layer. Waterproof tape is widely used and can be used for waterproofing joints of communication equipment base stations, antennas, spy wires, etc.,
as well as waterproof sealing protection of overhead insulated wire joints. Let’s learn more about it with the editor below.
Features of waterproof tape
1. Good conformability to irregular surfaces;
2. Good compatibility with various cables;
3. Self-melting tape;
4. Wide operating temperature range;
5. Excellent weather resistance and waterproof sealing performance;
6. Excellent bonding performance to copper, aluminum and cable sheath materials.
Classification and use of waterproof tape
The main purpose of waterproof glue is waterproofing, but waterproofing is also divided into many categories, roughly two categories, industrial waterproofing and home waterproofing.
If it is home waterproofing, it is recommended to use three-proof glue, which has good high and low temperature resistance; after curing, it forms a transparent protective film with excellent insulation, moisture-proof, leakage-proof, shock-proof, dust-proof, corrosion-proof, anti-aging, corona-resistant and other properties.
For industrial waterproofing, it is recommended to use the glue that my country will focus on developing, which are as follows:
Urea-formaldehyde glue with low formaldehyde emission: It is the adhesive with the largest output in my country. With the improvement of people’s living standards, the enhancement of quality awareness and environmental awareness, especially after joining the WTO, in order to occupy a place in the international market, it is imperative to produce urea-formaldehyde glue with low formaldehyde emission that meets international standards.
Polyurethane adhesive: It is widely used in shoemaking, construction, automobile and other fields, and is considered to be one of the most promising glues in China due to its excellent performance. In developed countries, polyurethane adhesives are used in shoemaking, and silicone and polyurethane adhesives are mainly used in building sealants. In addition, polyurethane adhesives are also used in food packaging and magnetic tapes, and their uses are very wide.
How to use PVC waterproof tape
1. The construction method of waterproof tape is based on the gap and seam width of the surface joints and the requirements of the engineering design, and the specifications and sizes are selected.
2. Wipe the surface joints and cracks clean.
3. Starting from one end of the surface crack, tear off the isolation paper on the asphalt tape and slowly open it along the joint in a straight line. Apply the asphalt tape to the joint and crack of the roof, and then gently press the asphalt tape with your hand to make the joint firmly bonded and tightly sealed.
