The protective film of stainless steel has many functions, mainly to protect the surface of the product, such as avoiding and reducing different degrees of damage during transportation, handling, processing and bending, and keeping the surface of the sheet clean, and it is also in storage. Time to avoid being corroded by the external environment.

However, when the protective film is affected by extreme environments, such as alternation of cold and heat, improper processing methods, high storage environment temperature and other factors, the film may be difficult to tear or there may be residual glue after the film is removed. How to deal with these situations?

1, the treatment method that the film is difficult to tear

The reason why the film is difficult to tear off is almost always due to the aging of the film after being left for too long.

The manufacturer’s instructions are to tear off the film within 6 months after the board leaves the factory.

The sheet is torn off the film within 10 days after processing and installation.

If it exceeds the specified time, it can only be torn slowly…

Remind customers and friends that there are stored plates, and you must use the earlier ones first. Because the early plates were generally stored at the bottom, many people didn’t want to take them because they were lazy, and as a result, time passed without knowing it.

Refer to the following processing methods

Slowly tear up the film at an angle of ∠90°;

Blow or scald the hard-to-tear film with an electric fan, hot water, etc., and it can be torn up when the temperature reaches a slight hot touch.

2. Treatment methods for degumming and glue residue

Long-term high temperature conditions (such as the product after installation in the sun, close to high-temperature objects) cause accelerated aging of the film;

Beyond the period of use;

There are chemical raw materials stuck on the film;

The impact of storage environment.

For details, please refer to the following steps

Materials to be prepared:

Glue remover, two wet towels, one dry towel, watering can with clean water.

Use spray to spray on the board surface with glue residue, let the glue removal liquid stay on the residual glue for about 10 seconds, and fully soak into the residual glue.

Wipe the spray with a wet towel to see if the glue is removed. If there is still residue, repeat the first step and use the same wet towel to wipe off the glue.

Wipe off the water with a dry cloth and observe the surface to confirm the effect.
