PLASTIC
Plastics has become the most important thing in our life. How many trousers are there in plastic around us? I'm doing a study on that plastics.
The composition of the plastics
Plastics discovery comes from an unexpected event. Christian Frederick Schoenborn is the German Swiss scientist who discovered the gas in the ozone. He was born in the year 1799. His wife was barred from repeatedly refusing to conduct chemical experiments at home kitchen. In 1845, one day his wife left for Shaunbin Kitchen. During the experiments, the beaker, who had a mixture of sulfuric acid and nitric acid, broke down. The acid wiped out with the cotton wool that had been worrying.
The fireful Apron
Showben, a sweeping cloth. The acid wiped off the apron fabric used during his wife's clothes. He immediately succumbed. Immediately pulling it near the oven for drying. An unexpected incident happened.
The fire that was placed in the unpollored fireplace was fire. Moreover, in the moments there was a slight disappearance of even ash.
Cellulose and guncutton
He never thought about the smoke that his wife would arrive at. The scientist inside the room awoke. Why the apron disappeared unusual?
The cotton is cellulose. A natural polymer. Nitrate is a mixture of sulfuric acid and nitric acid. Nitroly cellulose acts with cellulose, with a mixture of nitrate. Nitrous cellulose is an alluvial object. Nitro Cellulose was used as a gun cotton as a explosive substance.
The substance of Parsken
In 1856, Alexander Parks discovered that nitrous cellulose was incorporated into the alcohol and other materials could be made of plastic materials. Parks was the beginning of the plastic era. Different kinds of plastic products make and appreciate parks.
"Parsacon and celluloid have been built in a natural cellulose with a modification. Hence, it is the first man-made plastic bakalite. "
Different types of plastics
Polymers have a big place in today's world. From pens to space shuttles, covers to bags, brush to artificial hearts, cycle tire to airmen. Most of the indelible uses are made of polymers. Polymers can be divided into a natural polymer and synthetic or synthetic polymer. In addition to the polymers, rubber, plastics and nursery may also be classified.
Different types of plastics
There are two main types of plastics.
- Thermoplasty
- Thermosetting plastics
Thermoplasty
- Heat is heated and heated on cold.
- When hot weather does not change.
Thermosetting plastics
Once formed, the reactor can not be reversed without the breakdown of heat at high temperatures.
Abuse of Plastics
Plastics produced by industry based industries are misused.
"Plastic bags and plastic bottles used for packing and packaging are made to be abandoned after use."
Environmental problems
Plastic production and use will adversely affect the environment. We have to face the consequences and the generation to come.
Plastics are one of the reasons for the contamination of soil, water and air. The bin, digging and burning habit at the home of a plastic home for domestic use is essentially environmental pollution.
Solutions
- Prevent abuse
- Promote reuse
- Reorder
"Avoid the use of plastics and the abuse. The use of environmentally friendly alternative applications can be encouraged. "
