introduction
origin and significance of the project!At present, the popularity in the use of plastic bottles in food packaging and beverage has a lot. Due to the ease of use, easy to find at a very cheap price. These products are made of waste plastic.Rubbish is increasing every year. Because of the increase of the population. Economic growth and the industry. The main problems of the community which must be resolved. Garbage disposal by burn them.The gas, greenhouse effect, or global warming. The removal of one way, is buried. But recycling garbage can be decomposed. And long enough!The garbage in the home and in the school. Find garbage mainly plastic bottles, so party organizer and project pots from plastic bottle up, to reduce the waste. The problem of global warming.To advantage. The trash back into good environment as well
.
1. The objective of the project. To devise a pot from a plastic bottle
2.? To time to benefit, 3

.Plastics are organic compounds synthesized substitute natural materials. Some species when cooling down will harden. When the heat is also weak. Some kinds of curing permanent, there are many kinds, such as nylon, neoprene, use ทำสิ่ง, such as clothing.Container ship or car component
.Natural raw material for producing plastic
.The important raw material used for producing plastic. Products of petroleum, natural gas, coal, different minerals, mostly in addition may be produced from vegetable oil and various parts of the plant as well
- Petroleum
.Petroleum is the most important source of raw materials for plastic industry of every kind. The source of petroleum industry in many places. But no application to use in the field of plastic products.Products from petroleum refining petroleum. And can be used in plastic manufacturing industry important include substances in the olefin (Olefins), such as methane, ethane, propane and butane, pentane. And a group of substances in aromatic (Aromatics) such as benzene.Of the two groups can be used to produce many kinds of monomer has
.Natural gas -
.Natural gas found in Thailand contains a hydrocarbon that is methane, ethane, propane and butane. These hydrocarbons used as raw material in the production of ethylene propylene monomer and a monomer- coal and lignite

.The plastic number 1 called polyethylene pour Rafe faith (Polyethylne location Terephthalate) or better known as pet (PET or PETE) is a transparent plastic. Solid, impact-resistant, not fragile, and gas permeability. The bottle contains water, a bottle of water, it plants.Can be recycled fibers for sweaters, carpet, and synthetic fiber for stuffed pillow, etc.!The plastic number 2 named. Polyethylene, high density polyethylene (High Density Polyethylene) or call shorthand that HDPE (HDPE) is a tough and hard plastic broken Quite strong but stretch as much. Chemical resistant, and can be various shapesUsed to make bottles, water bottles and packaging for cleaning, shampoo, etc., can be used to recycle a bottle oil pipe plastic Artificial wood, etc.!The plastic number 3 named poly vinyl chloride (Polyvinylchloride) or better known as PVC (PVC) used ทำท่อน้ำประปา hose transparent film for wrapping food. Plastic sheet for the goal. The window and artificial leather.Traffic cone, furniture, plastic cassette cable bench wood imitation, etc.!The plastic number 4 named. Low density polyethylene (Low Density Polyethylene) can call shorthand that LDPE (LDPE) is a soft, sticky plastic Stretch as much, clear, durable, but not withstand the heat used to film.
