Abstract Science matters "Peel fruit Correction" can not remove the stuck under desks, chairs or floors to clean. By using kaffir lime peel fruit peel and grapefruit peel tangerine peel. Rub the skin with correction fluid. The results show that trace correcting fluid escapes. Keep the area clean up It is also economical and safe to use with other acknowledgments this project with great thanks to the teachers state pong Pongsapich stigma that provides advice, consulting and knowledge about science and project work, thanks to director. The academy To assist and advise the knowledge about the exhibit project. Courtesy of the materials and equipment used in scientific experiments. As well as the materials used in the exhibit. Thanks to the knowledge gained from this project to publish for the benefit to teaching science. The father thanks Mother and colleagues who cooperate well chapter. 1 Introduction The origin and significance of the current economic conditions we have faced the same problem. Many of you probably know Thailand's economy to plummet down alarmingly, it has an effect on prices of consumer products in the market have increased as well. Merchants and residents have trouble making the product expensive. And product sales are not Or goods in short supply, causing prices to move even more expensive. The butler, maid, you're probably worried about household expenditure to increase expenditure. But revenues also remain the same So we have to consult and find a solution to help you have a butler and maid. Household expenditure to abate somewhat. Which must start from what we use every day. And consumes very much like cleansers we use every day, and more expensive, we have developed a way to study. The trial period of eliminating artificial chemical peel fruit itself, which will reduce household expenses have slightly better. Water elimination period that we studied and presented this. All the raw materials come from nature for local non-hazardous household and also do not have to buy. To save money, many possibilities. How to make it easy stain remover period. Simply butler, maid Or those who are interested in education And to do it can do by yourself. But when we are successful, we may be able to share their knowledge with those who are interested but do not have time to study the document itself and the reasons given above. We make it interesting to try to eliminate periodic cleaning of citrus fruit peels discarded by the market. Or fruit on the tree that you would not put a lot of assumptions with citrus fruit peel can remove correction fluid (liquid. paper) The aim of the study 1. To study the peel fruit used to denigrate correction fluid on the table two. Of waste to be used to benefit the most three. The scientific process applied. The benefits to themselves and the public 4. To promote the initiative to train themselves to become a scientist? The scope of the study 's project. Peel fruit Correction The study defines the scope of the study were as follows grabbed scope 1. Content - The benefit of bergamot, tangerine, lemon and grapefruit - A list of equipment and chemicals - Methods 2. Scope of the period of study at the time. The study is from July 2557 to October 2557 Month peel fruit, bergamot, tangerine peel experiments four types of lime and grapefruit. The rub correcting fluid (Liquid Paper: liquid paper) following its desk chair slats compared the peeling of correction fluid Liquid Pepe's (Liquid Paper: liquid paper) terminology first. . correction fluid means a liquid over a solid white label used for error messages in the document. And when dry, can be overwritten. Typically, correction fluid is contained in a vial. And a lid with a brush attached. (Or perhaps a piece of foam triangle) which dip liquid in the bottle. Brush the liquid onto the paper used for labels. Prior to the invention of the word processor. Correction fluid is extremely popular for the printing typewriter. The first form of correction fluid was invented in AD 1951 by the founder of the company secretary Bette Nesmith Graham and Liquid Paper. By entering into a bottle containing white nail polish. Brush white label solution on paper that printed the wrong one thinner, as correcting fluid containing organic solvents. (VOCs) solution that is not used for a long time because it will thicken more as the solvent to evaporate into the air. This may cause the liquid too thick to use. Or maybe it was dried. Therefore, manufacturers correcting fluid, some sold solvent is bottled separately called thinner putting thinner few drops into the bottle, it causes fluid back to normal thinner that. This was composed of toluene. Which has been banned because it is carcinogenic. In later changed to. 1,1,1- tri-chloro ethane. It has been banned by the Montreal Protocol (Montreal Protocol), since the substances that destroy the ozone layer. The transition to the tri-chloro-ethylene, which is not safe from it. Currently, thinners are used in correcting fluid containing bromo propane. In order to avoid inconvenience to the use of organic solvents. For reasons of safety and recruiting. Correcting fluid can make some use of water as a solvent. But it has the disadvantage that it takes longer to dry. And can not be used with certain types of ink. This will make the color ink mixed with liquid.
