Paper production methodologies.The paper begins to make wood pulp fiber. to come out, and then apply the membrane has to be mixed with additives in various ratios to adjust paper treasures, usage needs. This sheet from the nanam to using machines, paper manufacturing, and then processed applications. The production process is divided in five steps by sorting according to the actual operations within the plant are as follows:1. the production of pulp (Pulping).2. to prepare a water pulp (Stock Preparation).3. to make a sheet of paper (Papermaking)4. update the paper sheets while walking treasure (Web Modification.)5. processingPulp production. The primary purpose of producing tissue to separate out the fibers from wood of khuep or other forces. Pulp production can be done in several ways, either by chemical or mechanical methods, in some cases, it may be through purification, white before. In the production of pulp and molasses production consists of bleached pulp.Pulp production methodologies (Pulping Process). There are several different types of tissue, also called production methodologies, which may consist of various forms of energy: thermal energy, mechanical energy, and chemical energy. The production of mechanical pulp (Mechanical Pulping Process) to use mechanical energy coupled with thermal energy in separating the fibers come out. By timber/wood pieces will be sent to the crusher, which serves to crush and cut a piece of wood into wood pulp bits. A membrane called the grinding or mechanical wood pulp, pulp, pulp yields of more than 85 percent range in wood pulp grinder has a relatively well harshness fibers that were mostly incomplete. There is a lack of, and cut a thon. There is also a group of fibers are mixed with. In the wood pulp grinder consists capillary fibers (fines), which is caused by the tearing of fibers, fibers, single (individual fiber) are rarely complete, coherent, and request fiber (bundle of fiber), which consists of multiple fibers stick together as a coherent. This type of tissue to be used as raw material for making paper, meets all three components, namely, capillary fibers to add opaque features. The fibers, which are rarely perfect and there is still a lot you trade on the big bend lip. Making the bonding between a low fiber diet Back color fast. This type of tissue, so it is not suitable for high-load paper or store it for a long price is suitable for publication such as a newspaper or cheap used as inner cardboard pulp. The production of Chemical pulp (Chemical Pulping Process) to produce tissue-based methodologies will be used phayang chemical and heat energy in July, making the fibers separate. By pieces of wood will be sent into the boiler, chemical pulp (digester), and each pattern on the outside lip products to the rest part no chemical pulp tissue is Lai has multiple types called chemicals used in manufacturing, such as sulphate pulp. Soda pulp and sulphite pulp. Pulp, chemical pulp yields about 40 percent soft, relatively dark color looks. The fiber is complete. This type of tissue with very high consumption. Because of the potential of the fiber can be developed to be used extensively. All applications received and for communication. If used in a job such as packing paper to not necessary, but if it is used to communicate, they must be taken to make bleached white before. เยื่อและเศษกระดาษ (Secondary Pulp) ในปัจจุบันเศษกระดาษ (reclaimed and waste paper) นับ ได้ว่าเป็นแหล่งเส้นใยที่สำคัญแหล่งหนึ่ง ได้มีการนำเส้นใยกระดาษที่ใช้แล้วทั้งภายในและภายนอกประเทศมาเป็นวัตถุดิบใน การผลิตกระดาษ เยื่อที่ได้จากเศษกระดาษที่ใช้แล้วเรียกว่า secondary pulp ส่วยเยื่อที่ยังไม่เคยใช้ทำกระดาษเรียกว่า virgin pulp เส้นใยที่ได้จากเศษกระดาษชนิดนี้เรียว่า recycled fiber เนื่อง จากกระดาษที่ผ่านการใช้แล้วมีมากมายหลายประเภท เช่น ถ้าเป็นกระดาษที่ผ่านการพิมพ์ต่าง ๆ ก่อนนำมาทำเป็นเยื่อต้องผ่านกระบวนการเอหมึกออก (deinking) เสียก่อนแล้วจึงนำไปฟอก (bleaching) ให้ ขาว สำหรับนำไปผลิตกระดาษสำหรับพิมพ์ หรือกระดาษชำระ แต่ถ้าจะนำไปผลิตกระดาษเหนียว หรือกระดาษสีน้ำตาลก็ไม่จำเป็นต้องเอาหมึกออก เยื่อจากกระดาษหรือเศษกระดาษที่ได้ส่วนมากจะนำไปเป็นวัตถุดิบในการ ผลิตกระดาษพิมพ์เขียน ทำเป็นเยื่อชั้นในกระดาษแข็ง หรือทำกระดาษชำระเป็นต้นPulp bleaching (Bleaching). Hemodialysis membranes is to make pulp white paper suitable for various communication is divided into two ways:How to eliminate the pulp bleaching lip on the outside (removing lignin).Pulp bleaching methods to change the color of the lip on the House are in a colorless Chemical pulp (lignin bleaching) are bleached using a chemical reaction with the Bikini on the lip are priced on the outside. This model has several purification steps. In General, there will be 3-6 steps (CEH CEDEP CEOP) membranes have a bright white, 80-95 percent when measured with a measuring Elrepho step in laundering is named by using the chemical purification and purification procedures are sorted according to alphabet used, such as laundering form CEDED.Chemical purification steps are called symbols.C-step Chlorine chlorinated nation (chlorination stage.)Sodium hydroxide in steps E Aix-en-Provence, insert (extraction stage).Chloride Calcium hypochlorite stage hypochlorite H (the hypochlorite stage).Chlorine dioxide chlorine dioxide stages D (chlorinedioxide stage).Peroxide Hydrogen peroxide stage P (peroxide stage.)O stage Oxygen oxygen (oxygen stage.)Ozone ozone (ozone stage), a stage Z.Zhi app A-step Acid (acid stage.)Preparation of pulp juice This membrane water preparation stage has two major objectives is to develop the potential of fiber by applying tissue to grind and update the paper treasures, intended use, or by mixing different types of additives according to the ratio of a given ingredient, this is called "pulp" juice "or" stock "(stock) that brings all kinds of paper goes through grinding, more or less pulp to the next level. Some types of tissue do not need grinding, such as wood pulp, pulp mill, merge, make new ones. In this step, the preparation of a water membrane comprising various acts to crush and mix by operating procedures are sorted as follows:1. to distribute the fibers so that the tissue distribution (defibering) fibres are separated from the water by freedom.
