The production process of Glasin paper

Pulp preparation

The production of Glasin paper first requires the preparation of pulp. Pulp can be made from wood pulp, bamboo pulp, waste paper and other raw materials. First of all, the raw materials are crushed and divided, and then the right amount of water is added to stir to make it into a paste. Then, the paste is filtered, dehydrated and other processes to obtain pulp.

Pulp adjustment

In order to adjust the properties of the pulp so that it is suitable for the production of Glasin paper, the pulp adjustment is required. The main purpose of adjustment is to adjust the humidity, PH value and viscosity of the pulp and add certain fillers and whitening agents to improve the strength and luster of the paper.

Pulp forming

After the pulp is adjusted, it needs to go through a molding process to turn it into paper. There are two main forming processes: warm mesh forming and dry mesh forming. Wet mesh molding is the pulp evenly poured on the net through the evaporation of water and pressure, so that the paper is formed. Dry mesh molding is to spray the pulp on the net and dry it with hot air to make the paper quickly formed.

Paper processing

The formed paper also needs to undergo a series of processing procedures to improve its quality and luster. The first is the calender process, through high temperature and high pressure hot pressing treatment, so that the surface of the paper is smooth and flat. This is followed by the coating process, where a film is applied to the surface of the paper to increase its gloss and waterproof properties. Finally, the cutting and packaging process, the paper will be cut in accordance with the specified size, and packaging, convenient storage and transportation.

Quality inspection

In order to ensure the quality of Glasin paper, strict quality testing is required during the production process. Mainly includes the thickness of paper, strength, gloss, flatness and other detection indicators. Through the use of professional testing equipment and methods, the paper is comprehensively tested to ensure that it meets the standard requirements.

Glasin paper production process through many links of fine operation and adjustment, and finally get high-quality paper products. This kind of high-grade paper has a wide range of applications in various fields, which brings convenience to people's life and work. With the continuous progress of science and technology, the production process of Glasin paper is also constantly improving and innovating to meet the needs of the market and people's pursuit of paper quality.
