The paper production industry is one of the oldest and most important industries in the world that has long played an important role in the cultural, educational and economic development of societies. The paper production process involves various steps, each of which requires the use of special machinery and equipment.
1. Doughing machines
The paper production process begins with paste. At this point, raw materials such as wood, bugas (sugar cane) or recycled paper are converted to paper paste. Paste machines are divided into two types of mechanical and chemical:
Mechanical Dough Making: In this way, wood is chopped and converted to dough using mechanical machines.
Chemical Dough Making: In this method, wood is converted to paste using chemicals such as sodium hydroxide and sulfite sulfite.
2. Dough purifiers
After producing the dough, the dough should be refined to remove impurities and excess particles. Dough purifiers refine the dough using mechanical and chemical processes and are ready to use it in the next step.
3. Paper Machine
At this point, the refined dough is transferred to the paper machine. The paperwork includes several sections:
Forming Section: In this section, the dough is spread to a lattice strip and extra water is separated from it .
Press Section: In this section, the dough sheet passes through the compressive rollers and more water comes out. Section: In this section, the sheet of paper passes through the hot cylinders and dries completely.
4. Coverage and Completion Machines
To improve the quality and specific properties of paper, it may be necessary to apply different coatings on the paper surface. This is done using coating machines. Also, complementary machines include cutting, laminate and packaging machines that make the paper final and usable.
conclusion
Introduction to paper production machinery and equipment is very important to improve the efficiency and quality of production in this industry. From dough machines to covering and complementary machines, each play a vital role in producing high quality paper. Using modern technologies and advanced machinery, you can improve the production and cost reduction process.
