We all often use paper for various purposes, whether for writing, reading, or perhaps to wrap dumplings. Use the paper we often were usually made of wood mixed with modern technology so that through our hands. To learn more about the paper that we use let us learn the process of making paper.
Paper Making Process (pulp)
Wood taken from production forests then cut – cut or better known as the log. Logs stored in the shelter a few months before it is processed in order to dissolve the log and maintain the sustainability of raw materials.
Discarded wood or leather with a machine known as the De – Barker
Wood cut – cut into small size (chip) with a chipping machine. Appropriate chip size is taken and is not suitable reprocessed.
Chips cooked in a digester to separate the wood fibers (materials used to make paper) with lignin. The cooking process there is two kinds of chemical and mechanical pulping process of the pulp process. Results from the digester are called pulp (pulp). Is processed into paper pulp in paper machines (paper machines).

Paper Making Process (Paper Machine)
Before entering the machine processed paper pulp into the first area in preparation for the shares. This section serves to draw on raw materials such as: adding dyes to the paper (dye), add substance retention, add filler (to fill the pores – pores between the fibers of wood). Material that comes out of this section is called stock 9campuran pulp, chemicals and water).
From stock preparation before entering the headbox is cleaned first with a tool called cleaner. From the cleaner into the headbox stock. Headbox serves to form a sheet of paper (information) above fourdinier table.
Fourdinier serves to remove water that is in stock (dewatering). The results that came out called by the web (wet paper). Density levels around 20%.
Press part serves to remove water from the web so that the solid content reaches 50%. The result is entered into this part of dryer (dryer). How this part is working press. Between two rolls of paper into a spin. One rolls the top of the berries so that the water pressure out of the web. This section can save energy, because the dryer did not work too hard (the water has been discharged 30%).
Dryer works to dry the web so that the water level reached 6%. The result is rolled up in the pop-shaped reel that big roll of paper (paper roll). This roll paper is cut – cut to size and delivered to the consumer.
