What are the requirements of the Glassine paper making process

- Jul 14, 2017 -

We are common to the separation of paper, in fact, the paper is the isolation paper, he is a kind of prevention of prepreg adhesion paper, but also to protect the prepreg is not contaminated with sticky paper, and the type of paper is also divided into many, usually divided into plastic-free paper and plastic out of paper, in addition to the separation agent can be divided into silicone-type paper and non-silicon paper. So what are we going to meet when we make the paper?
First, to be able to adhere to prepreg, but have to be easy to separate the two;
Second, do not and resin system chemical reaction or will pollute the resin system;
III. The elongation rate of the paper is also consistent with the fiber after traction, thus preventing the deformation or distortion caused by the prepreg in the process of preparation, but in general, its thickness, unit area and quality are not so easily controlled;
Four, to have enough compactness, so as to prevent moisture through it to enter the Prepreg;
The paper is a silicon oil paper or a sticker, mainly used for the isolation of sticky objects. The main features of the paper are as follows:
The first type of paper moisture resistance, temperature and so on. The paper contains silicone oil, and silicone oil has a certain temperature resistance, but this is mainly in the use of products, as well as domestic and imported silicone oil selection. General silicone oil temperature can reach about 150 degrees.
The peel strength of the second release paper: Peel force refers to whether the product can be easily torn down, of course, there is a strict test procedure. Small slitter, the international current main use GB. The unit of stripping force is gram. According to the results of the test is not the same, generally divided into three procedures, light, medium and heavy off type. The light is the type of paper and adhesive tape can be easily peeled off, and in the form is not very easy to peel off, and the heavy separation is difficult to peel off.
The third type of paper cleanliness is actually refers to the appearance of cleanliness and cleanliness. Because the work environment of the paper factory is different, it is very difficult to be in the dust-free room, in general, the plant better in environmental protection and environmental aspects have a great advantage, because these will have an impact on cleanliness. A lot of the cleanliness of the paper is not contaminated during the production process. A large extent is due to the cut in the time, due to cut the cleanliness of the factory is not high, resulting in electrostatic adsorption dust.
Five, even if the temperature and humidity of the environment changes, the length of the paper, width can remain unchanged, so as to avoid the wrinkle of the paper from the pre-dipping material wrinkles.
