What are the copy paper manufacturers telling you about the paper products in your life? What is copy paper? There is a relatively high-level cultural paper, perhaps you rarely care about it, but more or less similar paper products, it is copy paper. Today, let's walk into the copy paper manufacturer and take a look at what kind of copy paper is there in life?

Copy paper is a kind of high-grade cultural industrial paper that is difficult to produce. The main technical characteristics are: high physical strength, excellent uniformity and transparency, and good surface properties, fine, flat, smooth, and bubble-free Sand foam, good printability.

Generally, the production of printing paper is divided into two basic processes: pulp and papermaking. Pulp is the use of mechanical methods, chemical methods or a combination of both to dissociate plant fiber raw materials into natural pulp or bleached pulp. Papermaking is the process of combining pulp fibers suspended in water into paper sheets that meet various requirements through various processes.

Copy paper manufacturers generally need to store raw materials sufficient for 46 months to allow the raw materials to undergo natural fermentation in storage to facilitate pulping and to ensure continuous production of the paper mill. After the material preparation section, the raw materials such as reed, wheat grass and wood are cut into pieces or wood pieces, and then the small pieces of raw materials are put into the digester to add chemical liquid, and steam is used to cook the raw materials into pulp or wood pieces. It can be ground into pulp on the machine, or it can be ground into pulp after a certain degree of cooking.

Then wash the pulp with a large amount of clean water, and remove the coarse flakes, knots, stones and sand from the pulp through screening and purification. According to the requirements of the paper type, bleach the pulp to the required whiteness with a bleaching agent, and then use the beating equipment for beating. Then add various auxiliary materials such as fillers, sizing agents, sizing agents, etc. to the pulp to improve the performance of the paper, and then purify and screen again, then send it to the paper machine to filter water, press dehydration, dryer drying, and calender rolls. Take it and perform slitting, rewinding or cutting to produce roll paper and flat paper. If the production is to produce coated printing paper, it is necessary to dry the middle part or produce it into a web after coating processing.

In addition to the above basic production processes, copy paper manufacturers also include some auxiliary processes, such as the preparation of cooking liquid, the preparation of bleaching liquid, the cooking of rubber materials, and the recovery of chemicals and heat in the cooking waste liquid and exhaust gas. How to understand and judge Is it a really good copy paper? In fact, it is very simple. Firstly, check whether its appearance is smooth and delicate, and for uniform light transmittance. Secondly, check its physical strength performance, indicating high tearing degree, indicating that the higher the transparency of the copy paper, the higher its quality. Generally good copy paper, take 17g/m2 copy paper as an example, usually can cover 6-8 layers, and extremely good 12 layers.
