In modern life, the importance of paper and paper products for both home and office is self-evident, which is naturally inseparable from the paper industry. In the paper industry, professionals often mention paper, pulp, and cardboard. So what is the difference between these three? Let the editor of Sichuan Guanbang Machinery Manufacturing Co., Ltd. give you a specific introduction:
Paper is the first of the the Four Great Inventions in ancient China. It has played a great role in the dissemination and development of culture. Paper in the papermaking industry is usually divided into six categories: packaging paper, printing paper, industrial paper, office and cultural paper, household paper, and special paper. If these six types of paper are subdivided, they can be divided into various other types of paper. The specific raw materials that will be produced into what kind of paper are not only related to the raw materials, but also to the type of pulp and paper making equipment and paper machines
Pulp is a pulpy substance made from plant fibers through different processing methods. Paper is also made from pulp through papermaking machinery. Usually, fibers can be processed into pulp through chemical pulping and papermaking mechanical pulp, or a combination of these two methods. Therefore, pulp can be divided into chemical pulp, mechanical pulp, and chemical mechanical pulp
Cardboard is a thick paper made by processing pulp and interweaving fibers, which is often distinguished from paper only by quantity and thickness
The above is the specific content introduced by the editor of Sichuan Guanbang Machinery Manufacturing Co., Ltd. In short, in the paper industry, paper, cardboard, and pulp are only different terms for plant fibers at different processing periods
