Paper making process - Paper is a common object that we often encounter everyday, at school, at home, on the road as possible, in printing, the paper has been used a lot from the road first, but there are still many people who still do not understand the paper making itself, even though they have been using it for years and even decades.
What is the meaning of paper?
Paper is a material object in the form of thin or thick sheets. Materials that are often used in the process of making paper generally are wood fibers mixed with chemicals as fillers and reinforcement paper.
" Initially the wood that is often used in the process of paper making in Indonesia is generally fragile short fibrous wood like Akasia so it is easy to process and mixed with long fibrous wood for example pine trees to strengthen paper. This mixing process is carried out using a paper making machine (paper machine)."
But because of the increasing demand for paper, and the development of pulp processing technology that is progressing now almost all tree species can be used for paper-making materials. For example, trees can be made such as bamboo, papyrus, straw, sugar cane, flax and many more. For more details about paper-making material, it will be explained below.
Why is paper used as a medium for writing?
Paper has the ability to absorb liquids such as ink, water, and coloring agents from stationery so that they can be used as writing, drawing and printing media. Paper is very suitable for writing or drawing using stationery such as pens, markers and other stationery pencils because of its fast drying characteristics.
Paper is generally brightly colored so that it can display objects well and to sharpen the visuals made on the surface of the paper, so that it can be viewed or read.
What is the difference between paper and books?
Paper is part of the book, to mention the number of papers usually used the term sheet, so that we often use the term sheet of paper (which means one sheet of paper). While the Book is a collection of papers bound into one and given a cover to make it stronger and not easily separated / separated.
What are the uses of paper?
Very much the benefits of paper, paper is an object that really helps us in everyday life, such as to print school books, make notebooks, for walls, for packaging and many other uses.
What materials can be used to make paper?
Paper Making Process - Paper-making raw materials that are often used include:
- Wood
Generally paper is made from wood raw material. The wood used is wood which has a lot of fiber and some have little water content.
- Bamboo
Asian nations, especially China, Korea and Japan, make paper from bamboo trees. Bamboo is a raw material that is easily available to them because the climate and the area are a good support for bamboo plants. Bamboo is the material of choice because in addition to being easily obtained it is also cheaper than the price.
- Papyrus
Papyrus trees are trees that grow and can be used by the Egyptians as raw material for making paper. This Egyptian nation which according to historical records became the pioneer of paper making in the world.
- Animal Skin
The skin is also used by some circles for raw materials in making paper. What is commonly used is the type of sheepskin because the material is also rather easy to obtain even though not as much as from wood or bamboo raw materials.
What is the paper making process?
Even though we all agree that almost every day we use paper and cannot prison from paper, but do you know how to make paper? Well for those who don't know, here I will share information from several sources about the Paper Making Process.
Pulp / pulp
Wood is taken from the production forest then cut into pieces or better known as logs. Logs are stored in a shelter a few months before processing with the aim to soften the log.
Setala is removed from the skin with a bark paring machine or often known as De-Barker.
Wood cut - cut into small sizes (chips) with a chipping machine. In this process the chip that matches the size is taken and the inappropriate one is reprocessed.
The chip is cooked in a digester to separate wood fibers (ingredients used to make paper) with lignin. This cooking process has two types, namely Chemical Pulping Process and Mechanical Pulping Process. The results of this digester are called pulp. This pulp is processed into paper on a paper machine.
Paper Making Process
The pulp is processed in the Stock Preparation section. This section serves to gather raw materials such as: adding dye to paper, adding retention agents, adding fillers (to fill pores between wood fibers), etc. The material that comes out of this part is called stock (a mixture of pulp, chemicals and water).
- From stock preparation into cleaning with a tool called Cleaner.
- From the cleaner stock goes to the headbox (heater) which functions to form a sheet of paper (forming a formation) above the Fourdinier Table.
- Its function is to remove water in the stock (dewatering). The results that come out are called web (wet paper). The solid content is around 20%.
- Then enter the Press Part function to remove water from the web so that the solid content reaches 50%. The way this press machine works is that the paper enters between two rotating rollers. One roll of the top is put under pressure so the water comes out of the web.
- The last one to Dryer was to dry the web so that the water content reached 6%.
Finishing Stage
Finally, dry paper is wrapped around a large roll (paper roll), where it will be processed further depending on its final use. The paper is flattened and compacted further by passing metal rollers called calenders.
Wood is taken from the production forest and cut into pieces or better known as logging.
The log is stored in a shelter a few months before it is processed with the aim of softening the log and keeping the raw material. The wood is removed from the skin with a machine or known as De-Barker. A suitable size chip is taken and an inappropriate one is reprocessed. The chip is cooked in a digester to separate wood fiber (the material used to make paper) with lignin.
This cooking process has two types, namely Chemical Pulping process and Mechanical pulping process. The results of this digester are called pulp. This pulp is processed into paper on a paper machine.
Now that's an overview of the paper-making process, hopefully it can provide insight for you, thank you for visiting and see you later.
