How to use the special adhesive tape for battery energy storage correctly?

Proper use of special adhesive tape for battery energy storage is very important to ensure the performance, safety and reliability of battery energy storage system. The following are some key points:

Preparation before use

Cleaning the surface: Before sticking the adhesive tape, make sure that the surface of the adhered object is clean, dry, free of oil, dust and impurities. You can use a special cleaner or clean non-woven fabric dipped in a proper amount of solvent such as isopropanol to wipe it, and then let the surface dry sufficiently to ensure that the adhesive tape can closely adhere to the surface of the adherend and obtain the best bonding effect.

Cutting size: according to the actual length and width, use sharp scissors or cutting tools to accurately cut the tape. When cutting, make sure that the incision is neat and smooth, and avoid burrs or gaps, so as not to affect the sticking effect and aesthetics of the tape. At the same time, a certain margin should be reserved to prevent the tape length from being insufficient during the pasting process.

Paste process

Alignment and Sticking: Carefully align the cut adhesive tape with the parts to be pasted, so as to ensure that the edge of the adhesive tape is aligned with the edge of the adherend to avoid skew or deviation. For the adhesive tape that needs to be pasted on high-precision parts such as battery pole pieces, positioning fixture or template can be used to assist pasting to ensure the accuracy and precision of pasting.

Sticking slowly: When sticking the adhesive tape, slowly and evenly stick the adhesive tape on the surface of the adherend from one end to the other, and at the same time gently press the adhesive tape with your fingers or a special press roller to make it fully contact with the surface of the adherend, and exhaust air to ensure that the adhesive tape is firmly stuck. For the longer tape, it can be pasted in sections, and after each section is pasted, it should be fully pressed and checked to avoid bubbles or wrinkles.

Apply proper pressure: After pasting, apply a certain pressure to the adhesive tape with appropriate tools to further enhance the adhesive force between the adhesive tape and the adherend. Rubber roller, scraper and other tools can be used to roll or scrape the adhesive tape from the center to the edge with uniform force, so that the adhesive tape and the adherend can be attached more closely. For some parts that require high adhesion, the pressure can be appropriately increased for a period of time after pasting, such as 1-2 minutes, to ensure that the adhesive tape can give full play to its adhesion performance.

Post-paste inspection

Appearance inspection: After pasting, immediately inspect the appearance of the tape to see if there are bubbles, wrinkles, edge warping, degumming and other phenomena. If bubbles are found, you can gently puncture the bubbles with sharp tools such as needles, and then squeeze them out with your fingers; For wrinkles and warping, you can carefully uncover a part of the tape, re-paste it and press it flat; If degumming occurs, it is necessary to clean the degummed parts in time and re-paste or replace the adhesive tape.

Performance test: Some simple performance tests, such as adhesion test and insulation resistance test, are needed for the pasted adhesive tape to ensure that the adhesive tape can meet the requirements of the battery energy storage system. You can use tools such as tensiometer to test the adhesive force of the adhesive tape to check whether it can withstand a certain tension without falling off; Use the insulation resistance tester to test the insulation resistance of the tape to ensure that its insulation performance meets the requirements. If it is found that the performance is not up to standard, it is necessary to take timely measures to deal with it, such as re-pasting, replacing the tape or adjusting the pasting process.

Other precautions

Storage conditions: The special adhesive tape for battery energy storage should be stored in a dry, cool and well-ventilated environment to avoid direct sunlight and high temperature and humidity. Generally speaking, the storage temperature of adhesive tape should be controlled between 5℃ and 35℃, and the relative humidity should not exceed 60%. At the same time, it is necessary to avoid the contact between the tape and organic solvents, acids and bases and other chemicals, so as not to affect the performance of the tape.

Environment for use: In the process of using the adhesive tape, it is necessary to avoid pasting operation under harsh environmental conditions, such as high temperature, high humidity and strong wind. If it is unavoidable, it is necessary to take corresponding protective measures, such as sticking in a constant temperature and humidity environment, or using auxiliary tools such as a wind shield to ensure that the sticking effect and performance of the adhesive tape are not affected.

Safety protection: When using the special adhesive tape for battery energy storage, pay attention to safety protection to prevent the adhesive tape from contacting the skin and eyes. If the adhesive tape comes into contact with skin or eyes, it should be washed with plenty of water immediately, and seek medical attention in time. At the same time, avoid using adhesive tape near fire sources or flammable materials to prevent fire accidents.
