What are the requirements for the production of glassine release paper?

We often see release paper. In fact, release paper is release paper. It is a kind of paper that prevents the prepreg from sticking and can also protect the prepreg from contamination. The type of release paper is also divided into There are many, usually divided into plastic release paper and non-plastic release paper, and can also be divided into silicone release paper and non-silicon release paper according to the release agent. So what conditions do we have to meet when making release paper?

1. It should be able to stick to the prepreg, but it should be easy to separate the two;

2. Do not react chemically with the resin system or pollute the resin system;

3. After the release paper is drawn, its elongation must be consistent with the fiber, so as to prevent the prepreg from being deformed or twisted due to asynchronous drafting during the preparation process, but in general, its Thickness, unit area and quality are not so easy to control accurately;

4. It must be dense enough to prevent moisture from passing through it and entering the prepreg;

Release paper, also known as silicone oil paper or release paper, is mainly used to isolate sticky objects. The release paper mainly has the following characteristics:

The first release paper is moisture-proof, temperature-resistant, etc. The release paper contains silicone oil, and the silicone oil has a certain temperature resistance, but this mainly depends on the application of the product and the selection of domestic and imported silicone oil. Generally, the temperature of silicone oil can reach about 150 degrees.

The second peeling force of the release paper: the peeling force refers to whether the product can be easily torn off, of course, there are strict testing procedures. For small slitting machines, the international standard is currently mainly used. The unit of peeling force is grams. According to the different test results, it is generally divided into three programs, light, medium and heavy release. Light release means that when the release paper and tape protective film are attached, they can be easily peeled off, while medium release is not very good. Easy to peel off, while heavy release is difficult to peel off.

The cleanliness of the third release paper actually refers to the cleanliness and cleanliness of the appearance. Because the working environment of release paper manufacturers is different, it is almost rare to be in a clean room. Generally speaking, a better factory will have great advantages in environmental protection and environment, because these will affect the cleanliness. Influence. The cleanliness of many release papers is not polluted during the production process. To a large extent, it is due to the fact that the cleanliness of the slitting manufacturer is not high during the slitting process, resulting in electrostatic adsorption.

5. Even when the temperature and humidity of the environment change, the length and width of the release paper can remain unchanged, so as to avoid the wrinkling of the prepreg caused by the wrinkling of the release paper.
