Modern papermaking process can be divided into pulping, modulation, copying, processing and other major steps:

1. Pulping process
Pulping is the first step of papermaking. There are three methods to convert wood into pulp: mechanical pulping, chemical pulping and semi-chemical pulping.

2. The modulation process
Paper preparation is another key point of papermaking, paper after the completion of the strength, color, printing quality, the length of paper preservation period directly related to it. The common modulation process can be roughly divided into the following three steps: 1. 2. Beating; 3. Add glue and filling.

3.The main work of the paper making department is to interweave and dehydrate thin paper materials evenly, and then dry, calendering, rolling, cutting, sorting and packaging. Therefore, the common procedures are as follows:

1) Paper screening: dilute the prepared paper to a lower concentration, and use the screening equipment to screen debris and undissociated fiber bundles again to maintain quality and protect the equipment.

2) Mesh section: make the paper material flow out of the top box on the circulating copper wire mesh or plastic mesh and evenly distribute and interweave.

3) Press department: the wet paper removed from the mesh surface is led to two rollers with wool cloth, which further dehydrates the wet paper and makes the paper more compact, so as to improve the paper surface and increase the strength.

4) Drying cylinder: since the wet paper after pressing still has a water content of 52%~70%, it is impossible to use mechanical force to press and remove water at this time, so wet paper should be allowed to dry through many heating roller surfaces.

5) Paper roll: the paper is rolled into a paper roll by a paper rolling machine.

6) Cutting, sorting, packaging: take the front has been rolled into a tube of paper roll, with a paper slitter cut into sheets of paper, and then through manual or mechanical sorting, remove damaged or stained paper, finally every 500 pieces into a package (usually called a ream).

      Due to the characteristics of the electromagnetic heating roller, such as high temperature uniformity, accurate temperature control, long-term stable and reliable performance, it has become the most optimal equipment in the papermaking drying process.

      QiJieXin electronic technology co., LTD., is engaged in the development of hunan study electromagnetic heating roller industry for many years, successively presided over guangzhou, shenzhen, Shanghai, suzhou, shenyang, Taiwan, Japan and other regions and countries more than one project design and development, field installation and debugging, mastered all kinds of heating equipment application debugging work performance of electromagnetic heating roller, accumulated a lot of experience. Compared with the products of other companies, the electromagnetic heating roller produced by the company is more intelligent, safe, energy saving and environmental protection, with low maintenance cost, fewer faults and long service life. Thanks to the efforts of technicians, our electromagnetic heating roller has successfully broken through the high temperature of 500℃, with its surface temperature uniformity of ±1℃ and temperature control accuracy of ±0.1℃, and its long-term stable and reliable performance, which can improve the output and quality of customers' products. The company has been adhering to the "product quality as the life of the enterprise, as the development of science and technology as the soul of the enterprise" purpose, for the company to become the leading force in the industry and struggle!
