1. Pulp: A fibrous material that has been prepared and can be further processed (generally referring to plants derived from nature).
2. Pulp classification: According to the source of raw materials, pulp can be divided into wood pulp, non-wood pulp and waste paper pulp. According to the production process, pulp can be classified into chemical pulp, mechanical pulp and chemical-mechanical pulp, etc.
3. Wood pulp: It refers to the pulp produced from coniferous or broad-leaved wood through chemical, mechanical, or a combination of both methods. Including chemical wood pulp, mechanical wood pulp and chemical-mechanical wood pulp, etc.
4. Non-wood pulp: It refers to the pulp produced from the stem fibers of the Poaceae family (such as rice straw, wheat straw, reeds, sugarcane bagasse, bamboo, etc.), phloem fibers (such as flax and cotton dry bark, mulberry bark, mulberry bark, etc.), leaf fibers (such as dragon beard grass, sisal, etc.), and seed hair fibers (such as cotton fibers) through chemical, mechanical, or a combination of both methods. Including chemical non-wood pulp, chemical mechanical non-wood pulp, etc.
5. Waste paper pulp: It refers to the pulp made from recycled waste paper and waste cardboard.
6. Chemical pulp: It is a type of pulp produced by chemically treating plant fiber raw materials to remove a considerable portion of non-cellulose components from them, without the need for subsequent mechanical processing to achieve fiber separation.
7. Mechanical pulp: Pulp made entirely by mechanical means from various plant fiber raw materials (mainly wood raw materials) for the production of paper and paperboard. Such as pressure grinding stone wood pulp (PGW), wood chip thermal grinding mechanical pulp (TMP), and blasting pulp.
8. Chemical mechanical pulp: A type of pulp obtained from various plant fiber raw materials (mainly wood raw materials) through a combination of chemical pretreatment and mechanical methods, which is used for manufacturing paper and paperboard. Such as chemical mechanical pulp (CMP), chemically pre-treated wood chip grinding pulp (CTMP), bleached chemical thermal grinding mechanical pulp (BCTMP), and alkaline peroxide mechanical pulp (APMP).
9. Commercial pulp: It refers to the pulp distributed and sold in the commodity market (generally processed into pulp boards), excluding the pulp used by enterprises themselves.
10. Elemental chlorine-free bleaching (referred to as ECF bleaching) refers to a bleaching technology that uses chlorine dioxide instead of elemental chlorine as the bleaching agent.
11. Chlorine-free bleaching (abbreviated as TCF bleaching) refers to a bleaching technology that does not use any chlorine-containing compounds throughout the entire bleaching process. The main bleaching agents are hydrogen peroxide and ozone, etc.
12. Domestic waste paper recycling rate: It refers to the percentage of domestic waste paper recycled for the pulp and paper industry to the consumption of paper and paperboard.
13. Domestic waste paper utilization rate: It refers to the percentage of domestic waste paper recycled for the pulp and paper industry to the production of paper and paperboard.
14. Classification of paper and paperboard: Generally, paper is classified by its application into cultural paper (newsprint, printing and writing paper, copy paper, office paper, etc.); Packaging paper (commercial packaging paper, paper bag paper, food and candy packaging paper, etc.) Household paper (toilet paper, sanitary napkins, facial tissues, napkins, diaper paper, etc.) and specialty paper (functional paper required for finance, building materials, electrical and power, microelectronics, national defense, communication, food, medical care, etc.). Cardboard is classified into packaging cardboard (boxboard, corrugated base paper, white cardboard, etc.); Building cardboard (gypsum cardboard, soundproof cardboard, fireproof cardboard, waterproof cardboard, etc.) Printing paperboard (letterboard, cover paperboard, envelope paperboard, ticket paperboard, etc.) and special paperboard (jacquard paperboard, steel paper paperboard, spinning paperboard, shoe-making paperboard, filter core paperboard, insulating paperboard, high-temperature insulation paperboard, etc.).
15. Basis quantity: The mass of paper or cardboard per square meter is expressed in g/m ².
Generally, those with a basis weight of less than 225g/m ² are regarded as paper, while those with a basis weight of 225g/m ² or more are considered cardboard. With the development of paper and paperboard towards lower basis weight, the distinction between paper and paperboard is mainly defined based on their characteristics and uses. For instance, blotting paper and drawing paper with a basis weight greater than 225g/m ² are usually referred to as paper. Low basis weight paper generally has a specified weight of less than 40g/m ².
16. Market share: It refers to the total production capacity of all subsidiaries of a domestic or foreign-funded, joint venture or wholly-owned enterprise or group when calculating market share, rather than the production capacity of a single subsidiary of the enterprise or group.
