Chapter 2The associated document.The invention of the pencil project from a plastic glass. Study of the related documents. Is as follows:1. the invention.2. the plastic.1. the invention. The meaning of invention is about creativity, style, structure or composition of the product, including all the processes in the mechanism of maintaining or improving the quality of the product, or a new product, the cause is different from the original. 2. the plastic. Synthetic organic compounds are more plastic used instead of natural materials. When they cool down, they will get some anti-freeze. When I was young it was the heat. There are some kinds of curing many types, such as nylon, rubber fixed satellite. Used for things like clothing, containers, film, boat or car components.Natural raw materials for the production of plastic.The major raw material used for the production of plastic is petroleum products from natural gas, coal, minerals are mainly. In addition, it may be produced from oil plants and parts of plants.– PetroleumPetroleum is the most important source of raw materials for the plastics industry almost all kinds. Country of Thailand has many sources of petroleum production, but there is no benefit in making plastic products, only to be used as fuel only. Products derived from petroleum distillation and can be used in manufacturing plastics important: in group o le fin (Olefins), such as methane, e. The raphe mountain producers and nathe and pages in a group, Rose Mary Semitic (Aromatics), such as benzene and anupna of benzene. Both substances can bring production group 2 light through many types of polymer.– Natural gasNatural gas that is found in the country, Thailand has become a major hydrocarbons are methane, e. The raphe and producers as the majority These hydrocarbons are used as raw material in the production of ethylene, milk, dairy products and diversification ano ano Merry Merry, which is the default for many kinds of plastic production.– Coal and ligniteThailand is a major source of lignite country 2 is the Mae Mo Lampang province and Krabi. Benefits of lignite in addition to use as fuel for electricity generation. The production of benzene and derivatives of benzene, such as ano polymer recycling milk by stylist.– Plant and vegetable oilsThe raw materials used in the production of some types of plastics, namely, parts of plants and vegetable oils, such as cellulose and various fatty acids shellac.– The different minerals.Some, such as mineral coal coke credit and limestone as a raw material used to manufacture calcium carbide, used in manufacturing industry asethilin. In addition, the production of chlorine from the water, as well as asbestos has been used for production of glass reinforced plastic.The raw material is used as a default for the production of plastic substances derived from various sources, it will look like a single molecular hydrocarbons. Critics called the major international final, including vinyl chloride, ethylene vinyl fluoride. The diversification business hotel anhydrous watha e benzene Xylene and formaldehyde urea phenolic flattened lati HydeThe type and use of recycled plasticsTypes of recycled plastic are all 7 categories is.1. polymer called polyethylene thathi Lee reftha Let's nathe (Polyethylne Terephthalate) or known that pet (PET or PETE) is a good, solid impact resistant clear plastic. It is not brittle and gas permeation for good. Used for packing bottles, bottled water, vegetable oil, etc. Can be a fibre for recycling and Marie make sweater fabric for stuffed pillows and rugs, etc.2. polymer called polyethylene high density describes the League of nokwam (High Density Polyethylene) or relative whether HDL (HDPE) plastic PVC is tough and difficult. Somewhat stiff, but stretch. Chemical resistant and can be easily shaped. A bottle water bottles and packaging for cleaner Shampoo, etc. Can also be applied to marine oil pipe, bottle recycling, plastic crates, wood imitation, etc.3. called polyvinyl chloride (Polyvinylchloride) or known that PVC pipe (PVC) used to make the water supply hose clear film for wrapping food. Plastic film for the door. The artificial leather, etc. Recycling can be a water hose, marine or agricultural water table. Traffic cones Furniture bench plastic Cartridge tape cable harness wood etc.4. polymer called nokwam, low density polyethylene (Low Density Polyethylene) can be called the best p l e said (LDPE), a plastic that is soft and sticky, more transparent and durable stretch but not resistant to heat. Using film to wrap food wrap and bags of bread. Cool bags for packing food Can be a black bag for recycling marine trash? Bag trash. Artificial wooden furniture, floor tile, etc.5. a polymer (Polypropylene), polyester, raphi League brief call that Phi Phi (PP) as there are clear plastic, heat resistant and tough lines impact resistant. It is also resistant to chemicals and oils. Use food containers such as bowls, water tanks, baskets, platters, chilled bottles of sauce, put the barrel. Pharmaceutical packaging, glass bottles, yogurt can be a battery box in the Recycle Bin and Marie auto car parts such as bumpers and tail light for oil cone plastic broom, brush, etc.6. a stylish green polymer (Polystyrene), also known by the abbreviation PS (PS) that is transparent but brittle plastic that is easy to use and place container of food or foam insert, etc. Can also be applied to marine recycling wood hanger box video thoemomitoe bulb light switch panel ruler heat insulation egg tray machine tools.7. it does not have a specific name, but not the plastic one in six said in the above, but it is the plastic to melt.There are special purpose plastics.Polymethyl methacrylate (PMMA) used to place a contact lens phaenkrachok building (glazing) (trade names such as Perspex, Oroglas, Plexiglass) component of the fire sense fluoret. Turn off the auto light partsPolytetrafluoroethylene (PTFE) (under the name trademark Teflon) is used as a coating material, heat resistance and low friction, such as coating the Pan slider. Plumbing tapePolyethyretherketone (PEEK) (Polyketone) is one of the most expensive types of plastics are thermoplastic that is durable and heat resistant chemicals. Use various medical suppliesThis is in a plastic container for packing or storage of food, avoid plastics containing the symbol #, 3-PVC # 6-PS, or # 7-Polycarbonate and can use the plastic, s/s.
