Construction Preparation of Polypropylene Anticorrosive Tape in Different Environments

Release time:

2022-03-10

When we use polypropylene anti-corrosion tape, we need to be prepared before construction, but in addition to the materials and tools that need to be prepared before construction, the environment, weather, and temperature must also be prepared. The weather will also affect the construction of our products, so you should know how to deal with it. Then, let's learn about the construction preparations for different environments of polypropylene anti-corrosion tape!

1. Ambient temperature: If the temperature is low, the initial adhesion and adhesion will decrease. If the ambient temperature cannot be increased, the adhesive force can be increased by increasing the temperature of the coating water, heating with infrared rays, and increasing the temperature of the surface of the adherend and the tape itself.

Environmental humidity: If the humidity is high, the bonding speed will be lower, but the bonding force will be higher. When the humidity is low, the initial adhesion is strong, so in the operation, it is necessary to control the humidity of the coating water.

3. Coating water temperature: The higher the coating water temperature, the stronger the initial bonding force, but after a certain period of time, the bonding force of the polypropylene anti-corrosion tape decreases. Generally, normal temperature water is used, and hot water is also avoided in winter to avoid affecting the bonding effect.

4. In the face of the adhesion of polypropylene anti-corrosion tape, we usually need to deal with the overall conditions in use and install it in the face of the environment.

Polypropylene anti-corrosion tape is generally provided with partitions when it is not opened. This diaphragm mainly serves as a barrier tape. The effect of protecting the tape when not in use can be said to be very large. So, how should this separator be broken when in use?

1. Do not remove all the partitions before starting construction with polypropylene anti-corrosion tape. When the tape is wound, it can be peeled off synchronously.

2. Under normal circumstances, the circumference at the beginning of winding needs to be wound vertically. After the spiral winding is over, the anti-corrosion tape at the back also needs to be wound vertically.

3. In addition, when peeling off the isolation film of the tape, care should be taken not to contaminate the surface of the substrate, and there are no impurities on the surface of the substrate.

4. The work required for the surface treatment of the polypropylene anti-corrosion tape substrate is rust removal, welding slag, deburring and other work, and it is necessary to ensure that the surface is clean and dry without oil or dirt. Generally, rust removal by hand needs to reach St3 level, and rust removal by machine needs to reach Sa2.

5. When applying primer, use special primer. When leaving the fire, use a clean brush or roller to apply evenly. The use amount of the primer is usually about 12/L.

6. The primer surface can be wound after drying for about 5-10 minutes.

In various environmental temperature, humidity and other aspects we should do some preparation and some small methods worth learning. We need to keep learning about these things. Please keep the above points in mind. This can ensure that our construction has better and better results.

The above introduction is the construction preparation of polypropylene anti-corrosion tape in different environments. If you need to know more, please feel free to contact us!
