Chapter 1Introduction And the importance of the project Current popularity in the use of plastic bottles for packaging food and beverages with a lot due to the ease of use. Find cheap and these products will cause waste plastic, which is one reason that cause environmental problems and affect your health. Rubbish has increased every year since due to the increase of population, economic growth and industry. The community is an important issue that must be resolved. Incinerator to burn it by removing the cause of the pollution was caused to a gas. Greenhouse warming and global warming To get rid of garbage is another way to embed-but as a garbage can degrade and requires a long time. From a survey of waste in the home and in school. I found that most of the waste is the plastic bottle, so. Group ngankrathang's project idea from plastic bottles to reduce garbage problem, a problem of global warming and is also used to remove the rest of the work, is to benefit and make it waste to environment over the Internet or an intranet.The purpose of the project1. in order to fabricate pots from plastic bottles.2. to use the time available to benefit3. to practice meditation and creativity.4. to save the area in cultivation,Curious problems. The plastic bottles used to package food and beverage at all. The invention can be adapted to a beautiful planter.The scope of the project.1. in the period of December through January, 2555 (2012) 2556 (2013) 2. materials and equipment used in the project.1. plastic bottles.2. knives, scissors, rope, a copy.3. pencil, pen, ruler.*********************************************************************************************************Chapter 2The relevant documents.Potted artificial project from plastic bottles, study related documents. As follows:1. the invention.2. plastic.1. the invention. The meaning of invention is creative thinking about how element structure or mechanism of the product, including processes for manufacturing, maintaining or improving the quality of products, improved or new products that cause different from the original. 2. plastic. Plastic, synthetic organic compounds are used in place of natural materials. Some of these when it will cool down clotting. When it is hot, it melted the. There are some kinds of various types, such as fixed-erections, nylon, rubber, artificial. Used for things like clothing, films, containers, components, boat or car. Natural raw materials for plastic production. The major raw material used for the production of plastic products is derived from natural gas, petroleum, coal, minerals, mostly. In addition, may be produced from oil plants and parts of plants as well.– Petroleum Petroleum is the most important raw materials for the plastics industry almost all kinds. The country, there are many Thai petroleum producers, but there is no benefit in making plastic products, only to be used as fuel only. A product derived from the distillation of petroleum and oil can be used in manufacturing plastics, including significant substance in the group o le fin (Olefins), such as methane, e, Thane. The raphe-producers and nathe and page in the group rose Mary Semitic (Aromatics), such as benzene and anupna of benzene. Both substances can also be applied to group 2 produce light through many types of polymer.– Natural gas Natural gas that is found in the country, there are Thai component is a major hydrocarbons are methane, e, Thane. The raphe and producers is mainly. These hydrocarbons are used as raw material in the production of ethylene, milk and dairy products diversification ano ano Merry Merry, which is the default for many kinds of plastic production.– Coal and lignite There are 2 important sources of Thai national lignite is the Mae Mo Lampang province and Krabi. Benefits of lignite is also used as a fuel for electricity generation. The production of benzene and derivatives of benzene, such as milk, with a stylish Mercedes ano.– Plant and vegetable oils Raw materials used in the production of some types of plastic such as parts of plants, vegetable oil, such as shellac and various fatty acid cellulose.– Various minerals Some types of minerals such as coal, coke items, and limestone as raw materials used to manufacture calcium carbide, used in manufacturing industry asethilin. In addition, chlorine is produced from seawater, as well as asbestos has been used for the production of glass reinforced plastic. The raw material is used as a default for the plastics manufacturing from various sources, it looks as single molecules and hydrocarbons. Devlin called the final major critics such as ethylene, vinyl chloride, vinyl fluoride. Diversification-watha Dai e-benzene Xylene and formaldehyde urea phenolic & lati Hyde Types and utilities of plastics recycling Types of plastics recycling are all 7 categories:4_2-1-56 (500)1-4_3-56 (500) 1 number of plastic polymer called polyethylene thathi Lee nathe reftha Merah (Polyethylne Terephthalate) or known pet (PET or PETE) is a good, solid impact resistant clear plastic. Not brittle and better ingress of gas. Used for packing bottles, bottled water, vegetable oil, etc. Can a recyclable fibers for carpet and synthetic fiber sweaters for stuffed pillows, etc. 2 number of plastic called polyethylene polymer works League nokwam high density (High Density Polyethylene) or abbreviated as HDL p e (HDPE) plastic is tough and difficult. Somewhat stiff, but very stretched. Chemical resistant and can be easily shaped. Milk bottles used for water bottles and packaging for cleaner. Shampoo, etc. Can recyclable plastic bottle wooden crate engine oil pipes to harness etc. 3 number of plastic called polyvinyl chloride (Polyvinylchloride) or better known as PVC pipe (PVC) used for water supply hose and clear film for food wrap. Plastic film for making doors. Windows and artificial leather, etc. Can be recyclable as water pipes or water trough for agriculture. Traffic Cone Furniture bench plastic Cartridge tape, cable harness, wooden plates, etc. 4 number of plastic polymer called nokwam, low density polyethylene (Low Density Polyethylene) can get a good player, said PVC plastic (LDPE) is a soft sticky stretched a lot of bright and durable but not resistant to heat. Used to make the film.
