Jinling Machinery is not easy to find, a collection of terms for pulping and papermaking

　　1. Pulp

　　Fiber material prepared for further processing, which is used in papermaking, regenerated cellulose fiber and film and related industries.

　　2. dissolving pulp

　　Pulp mainly for the manufacture of regenerated cellulose fibers and cellulose chemical derivatives

　　3. air-dry pulp

　　technically refers to pulp whose moisture content is balanced with the surrounding environment, and commercially refers to pulp containing a specified moisture content agreed upon by both parties. When this specified moisture content is converted into dryness, it is called the commercial dryness of pulp.

　　4. pulping

　　The process of grinding plant fiber raw materials into fiber materials, or separating fiber materials from plant fiber raw materials by chemical or mechanical methods or a combination of the two.

　　5. Raw-material preparing

　　The necessary treatment process to make the stored plant fiber raw materials meet the requirements of the pulping method.

　　6. cooking

　　Heat treatment of plant fiber materials with water and chemicals.

　　7. bleaching

　　To a certain extent, remove the colored substances in the pulp or change the color of the pulp, and its purpose is to improve the brightness of the pulp, that is, the blue reflection factor.

　　8. Pulp or stock screening

　　Make the pulp paper pass through one or several screens to separate into qualified pulp or good pulp,

　　9. Waste paper waste paper

　　After treatment, it can be reused as paper or paperboard as raw materials for papermaking.

　　10. Chemical pulp chemical pulp

　　Pulp prepared by cooking plant fiber raw materials with chemical liquid to remove part of non-cellulose components. The chemical pulp in which the non-cellulose components have been removed much does not require subsequent mechanical treatment to separate the fibers, while the semi-chemical pulp only removes a small part of the non-cellulose components and requires mechanical methods to separate the fibers. Chemical pulp includes kraft pulp, caustic soda pulp, sulfite pulp, neutral or alkaline sulfite pulp and so on.

　　11. chemical-mechanical pulp

　　Pulp prepared by mechanically grinding chemically treated plant fiber materials.

　　12. mechanical pulp

　　Pulp made by mechanically grinding plant fiber raw materials.

　　13. refiner mechanical pulp

　　Pulp prepared by mechanically grinding wood chips or grass fiber raw materials without pretreatment and directly fed to humans with a disc mill.

　　14. stone groundwood pulp

　　The pulp made by grinding the peeled logs with a wood grinder.

　　15. paper-making

　　The process of further processing the pulp and preparing it into paper material, which is made into paper or cardboard on a paper machine or paper machine board.

　　16. Paper stock

　　A suspension made by mixing one or several papermaking pulps with other auxiliary materials for papermaking after being crushed and purified. This mixed suspension is called paper stock until the paper web is formed on the former of a paper or board machine.

　　17. paper

　　The plant fiber, mineral fiber, animal fiber, chemical fiber or a mixture of these fibers is deposited or laid on the forming wire of the forming device from the paper material suspension to form a paper layer, and the suspension medium is removed and dried. Evenly sliced.

　　18. formation formation

　　The process in which fibers are dispersed, arranged and interwoven to form a wet paper web or paper layers or multiple layers of paper with a stable structure and organization to form a wet paper web.

　　19. Paper web

　　A long continuous length of paper or cardboard during manufacturing and processing.

　　20. sheet (of paper or board)

　　cut into a piece of paper or cardboard with a certain length and width, also called flat paper or paper. Paper is also used to refer to formed paper in general.

　　21. trimmed width of paper or board

　　The width of the finished paper web obtained after cutting off the edge of the paper web on a paper machine or board machine or other finishing machinery and equipment.

　　22. Machine direction (longitudinal direction) of paper (MD)
