What should I pay attention to when using the special blue film adhesive tape for battery energy storage?

The following are some precautions when using the special blue film adhesive tape for battery energy storage:

surface treatment

Clean and dry: Before sticking the blue film adhesive tape, make sure that the battery surface and the parts to be stuck are clean and dry, free of oil, dust and other impurities. You can use a clean cloth or solvent to clean it, and then wait until the surface is completely dry before sticking it, otherwise it will affect the stickiness and sticking effect of the tape.

Surface flatness: The battery surface should be as flat as possible to avoid obvious unevenness or burrs, so as not to affect the fit between the adhesive tape and the battery surface, resulting in weak adhesion or bubbles, thus affecting the insulation and protection effect.

Paste operation

Avoid stretching: When sticking the blue film tape, try to avoid overstretching the tape. Excessive stretching may cause the tape to become thinner and longer, thus changing its original physical properties and viscosity, making the pasted tape prone to problems such as retraction and edge warping, and affecting the use effect.

Tight fitting: Apply the blue film adhesive tape to the battery surface evenly to ensure that there is no air gap or air bubble between the adhesive tape and the battery. Appropriate tools, such as scraper or roller, can be used to slowly and evenly compact the tape from one end of the tape to make it fully fit the battery surface, so as to achieve good insulation and fixation effects.

Joint treatment: If splicing tape is needed, make sure that the joint is firmly pasted and seamless. A part of the joint can be overlapped, and then compacted with tools to make it tightly combined, so as to prevent the joint from loosening or generating gaps during use, which will lead to battery exposure or degradation of insulation performance.

environmental conditions

Temperature control: The performance of special blue film adhesive tape for battery energy storage may be affected by temperature. Generally speaking, the pasting operation should be carried out in a suitable temperature range, and it is usually recommended to carry out it at room temperature (15℃-35℃). If the temperature is too low, the adhesive tape may become hard and sticky, making it difficult to stick. If the temperature is too high, the adhesive tape may become soft, easily deformed or overflow.

Humidity control: Environmental humidity will also have an impact on the sticking effect of adhesive tape. Excessive humidity may make the battery surface and adhesive tape absorb moisture, reduce the viscosity, and lead to poor adhesion; Too low humidity may make the tape generate static electricity and absorb impurities such as dust. Therefore, the blue film adhesive tape should be used in the environment with relative humidity of 40%-60% as far as possible.

Curing condition

First-generation blue film adhesive tape: If the first-generation blue film adhesive tape is used, it can be directly bonded, which is convenient to operate, but attention should be paid to compaction and fixation after bonding to ensure its conformability and stability.

Second-generation blue film tape: For the second-generation blue film tape, it needs to be started by UV irradiation before bonding, and then cured under appropriate conditions before bonding. In the process of UV irradiation, it is necessary to ensure that the irradiation dose and time meet the requirements of the adhesive tape in order to fully activate the viscosity and performance of the adhesive tape. Curing conditions should also be strictly controlled, usually at a specific temperature and time to ensure that the adhesive tape can achieve the best curing effect and performance.

Post-use inspection

Appearance inspection: After pasting, the appearance of the blue film tape should be carefully checked to ensure that the tape is free from wrinkles, bubbles, damage and glue overflow. If found, it should be handled or replaced in time.

Inspection of pasting effect: gently pull the edge of the adhesive tape to check whether the pasting is firm, and whether there are any phenomena such as warping and loosening. If it is found that the paste is not firm, it should be pasted again or other reinforcement measures should be taken.

Insulation performance inspection: For the blue film tape used for insulation protection, professional insulation testing equipment can be used to test the insulation performance of the pasted battery to ensure that it meets the specified insulation requirements and ensure the safe use of the battery.
