How the paper machine works
The working principle of the paper machine is mainly realized through the following parts: paper supply, stock distribution, dehydration, pressing, drying, pressing, rolling paper.
1. Paper feed part: The paper raw material is cut to the appropriate size and sent through a series of conveyor belts to the next stage.
2. Pulp distribution part: The pulp is screened on a rotating screen, and chemicals are added to improve its quality.
3. Dehydration stage: Water is removed from the pulp by high pressure and high speed rotation.
4. Pressing and drying: the pulp is compressed and further dehydrated.
5. Calender: Use high pressure and high temperature to smooth the paper and improve its quality.
6. Roll the paper: Roll the paper to the appropriate length and cut it.
The advantages of paper machines lie in their efficiency and flexibility. In addition, paper making machinery includes raw material preparation, pulping, paper making, until the production of rolled or flat finished products, as well as processing paper and board machinery, covering the entire production process from raw materials to finished products.

Process and application of filter paper
Raw materials for filter paper
The main raw material for filter paper is cellulose, which comes from the cell walls of natural plants such as cotton, wood pulp, etc. In addition, some chemical fibers can also be used to produce filter paper, such as polyester, polypropylene, etc.
The production process of filter paper
The production process of filter paper is relatively simple and generally divided into the following steps:
- Treatment of cellulose: Cut and crush the raw materials to make a cellulose mixture suitable for papermaking.
- Papermaking: Evenly apply the cellulose mixture slurry onto the felt of the filter paper machine, and through multiple processes such as vibration, compaction, and drying, make filter paper.
- Roll: Roll the processed filter paper into a roll for use.
Main performance indicators of filter paper
- Filtration efficiency: mainly refers to the filtering ability of filter paper for particles of different sizes.
- Resistance: Refers to the amount of resistance that needs to be overcome when filtering liquid through filter paper, which is an important factor affecting filtration efficiency and speed.
- Adsorption: Refers to the ability of filter paper to adsorb solutes of different components
Application of filter paper
Filter paper is a widely used filtering material in industrial production and laboratory testing. It can be used to filter impurities in liquids and gases, or as a chemical reagent and separation material.
Common application areas include food and beverage production, pharmaceutical manufacturing, environmental testing, coatings and cosmetics processing, etc.
In short, filter paper is an important industrial material, and its production process and performance indicators are directly related to its application effect. With the continuous upgrading of production technology and the expansion of application fields, filter paper will have a broader market prospect.
