Claims (3)

Claims (all) which will not appear on the advertisement page:------28/08/2020------(OCR) 1. Process of producing antibacterial paper for seat cushions. Flush toilet consists of step 1, papermaking process 1.1 chemicalpulping process. This method of pulping uses chemical energy and heat energy to separate the fibers. The raw materials used in the paper are sent. The digester, chemicals and heat will dissolve the lignin, leaving the undissolved part of the pulp. 1.2 Bleaching Pulp bleaching white pulp suitable for paper use 1.3 Preparation The pulping process is as follows: 1.3.1 defibering The fibers are separated so that the fibers are separated freely in the water by using a device called a hydropulper to disperse the fibers. Pulverizing (refining) to make the fibers branched into flaky to increase the potential of the bond between the fibers to be higher by putting the pulp to flow into the pulper. Inside the pulper, there are teeth to grind the pulp to break the fibers into Branch 1.3.3 Blending is the addition of an inhibitor of pathogenic bacteria to the membrane. It is crushed by mixing in the impeller tank, stirring at a speed of 5-6 rpm continuously for 20-30 minutes, then the pulp is stored in the tank. 1.3.4 Separation of impurities from the membrane water (screening and cleaning) The material larger than the fibers is rejected and passed into the cleaning machine to separate the other materials by using the specific gravity principle. The pulp has a concentration of 3-4%.1.4.Paper sheeting After mixing the pulp prepared from clause 1.3, the pulp will be sent to the paper machine to make continuous paper sheets 1.5 times. Improvement of paper properties can be done in two ways by choosing one of the following methods: Method 1, surface modification, when the paper passes through the drying ball, it enters the paper rolling section to improve the paper smoothness and increase the density of the texture. The paper resulted in thinner paper. Method 2: Improving the paper surface while walking the sheet with the surface plastering method, which is done before entering the paper baking ball by using starch paste on the paper surface to make the paper have a smoother surface. increase the strength of the thousand The paper surface makes the paper strong, which is additionally composed by the addition of an antibacterial agent. It can be added in the pulp mixing step or mixed with the starch water used for plastering on the paper surface. Step 2 Adding antibacterial agents. This can be done in 2 ways by choosing one of the following methods: Method 1 Add a selective inhibitor of pathogenic bacteria from Silverzeolite, Silvernitrate, Triclosan containing The amount of 0.06-0.07 (W/V) either mixed with 100% pulp water used to make paper before being sent into the paper machine prepared from clause 1.3 to make paper sheet method 2. Add a selective inhibitor of pathogenic bacteria from silverzeolite, silvernitrate, triclosan with any content of 0.06-0.07 (W/V). one by mixing with 100% starch water and put it on the paper surface before putting it on the paper baking ball. The coating will be the coating on both sides of the paper prepared from item 1.5 Method 2 of the papermaking process-- ----------Page 1 of the number 2 claims page 1. The process of producing paper to inhibit pathogenic bacteria for toilet seat consists of the first step, the paper production process 1.1 chemicalpulping process, in which the pulping according to this method uses chemical energy and heat energy to separate the fibers. The raw materials used to produce paper are sent to the digester. Chemical and heat will dissolve the lignin, leaving the undissolved part of the pulp. 1.2 Bleaching Pulp bleaching The pulp is white and suitable for paper use. 1.3 The process of pulp preparation is as follows: 1.3.1 defibering The pulp is distributed so that the fibers are separated freely in water using a device called a hydrapulper. (hydrapulper) to disperse the fibers 1.3.2 Pulping (refining) to make the fibers branched and flaky to increase the potential of the bond between the fibers to be higher by inserting the pulp water to flow into the pulper inside the pulper. There will be teeth to grind the pulp to break the fibers into branches. 1.3.3 Mixing the pulp (blending) is the addition of an inhibitor of pathogenic bacteria to mix with the pulp that has been crushed by mixing in the impeller tank, stirring at a speed of 5-6. RPM continuously for 20-30 minutes After that, the pulp is stored in a tank. 1.3.4 Separation of impurities from the membrane (screeningandcleaning) to remove material larger than fiber and pass into a cleaning machine to separate other materials by means of gravity. Specifications 1.3.5 Consistency regulator to control the consistency of pulp by keeping the pulp concentration 3-41.4 percent. Paper sheeting after mixing the pulp prepared from clause 1.3 has been completed. Then the pulp will be sent into the paper machine to make continuous paper sheets 1.5. Improvement of paper properties can be done in 2 ways: 1.5.1 surface modification. Roll the paper to improve the paper smoothness and increase the density of the paper, resulting in a thinner paper. 1.5.2 Improving the paper surface while running the sheet with the plastering method, which is done before the paper towel is baked using water. Starch is applied to the paper surface to make the paper smoother. It also increases the bond strength of the paper surface, which in addition to the addition of antibacterial additives can be added in the pulping process or mixed with water. flour that can be applied to the paper surface. Step 2 Adding inhibitors to inhibit pathogenic bacteria can be done by 2 methods as follows: Page 2 of the 2 pages Method 1 Add inhibitors to inhibit pathogenic bacteria that can be selected from Silverzeolite. ) Silvernitrate (Silvernitrate) Triclosan (Triclosan) with a content of 0.06-0.07 (W/V) either mixed with 100 percent of pulp used to make paper before being sent. To paper making machines prepared from item 1.3 to make paper sheets Method 2, add selective inhibitors of pathogenic bacteria from Silverzeolite, Silvernitrate, Triclosan. ) with an amount of 0.06-0.07 (W/V) either by mixing with 100% starch water and then plastered on the paper surface before entering the paper baking ball, which the coating will be coated on both sides of the Paper prepared from step 1.5.2 of the paper manufacturing process 2. Process of producing pathogenic bacteria-inhibiting paper for toilet seat according to claim 1, where blending is the addition of a selective inhibitor of pathogenic bacteria from silverzeolite, silver ni Silvernitrate, Triclosan, either 3. The process of producing paper that inhibits pathogenic bacteria for toilet seat according to the claim 1, which is additionally composed with the addition of an antibacterial agent, can be added in the process of mixing pulp or mixed with starch water used to plaster on the paper surface.
