clothes
Clothes are no longer limited to keeping warm. We dress more to beautify our lives and enhance our self-confidence. The influence of petrochemical products on human clothing is mainly the clothing revolution brought by synthetic fibers and artificial leather.
● Fiber Clothing Since China began to develop the synthetic fiber industry in 1959, it has been processed into various synthetic fiber garments such as acrylic fiber, polyester fiber, vinylon and nylon, which has solved people's clothing problems. A synthetic fiber factory, which covers an area of only about 4,000 square meters, can produce 90,000 tons of fiber every year, while to produce the same amount of wool, it takes 1600 square kilometers of land to harvest 90,000 tons of cotton and 40,000 square kilometers of pasture.
● Artificial leather Natural leather is limited by resources, animal protection and processing technology, and its use cost is high. Artificial leather is the earliest invented substitute for leather fabric. It is made of polyvinyl chloride, plasticizer and other additives by calendering and compounding on cloth. It has the advantages of low price, rich colors and diverse patterns. Polyurethane PU artificial leather and composite artificial leather are a new generation of products compared with PVC artificial leather, which are closer to leather fabrics. PU artificial leather is suitable for making leather shoes, bags, jackets and sofa cushions.
eat
As the saying goes, food is the most important thing for people, and food is the most basic need for human survival.
The petrochemical industry has improved the production efficiency of agricultural products and livestock products. Due to the application of chemical fertilizers and pesticides, the grain output has increased, and the grain production capacity of farmers has increased by at least 40%.
The plastic wrap and all kinds of food packaging boxes used in our daily life are made of synthetic resin. These food packaging materials prolong the shelf life of food and make our life more convenient and rich.

Housing is no longer just a shelter for modern people. People's requirements for "housing" should not only be beautiful and durable, but also be fireproof and noise-proof. The construction industry is the largest plastic user after the packaging industry, such as plastic floor tiles, carpets, plastic pipes, wallboard, paints and so on. , is also a petrochemical product. Environmentally friendly wood-plastic and aluminum-plastic composites have largely replaced wood and metal.
In addition to building materials, furniture and household items are all petrochemical products.
The use of gas freed people from the smoggy days of burning coal and firewood.

Nowadays, it is no longer difficult to take Wan Li Road. Modern means of transportation such as cars, trains, ships and airplanes have brought convenience and enjoyment to human travel, and it is petrochemical industry that provides power fuel for these means of transportation.
Petrochemical products such as plastics, rubber, coatings and adhesives have been widely used in transportation, reducing manufacturing costs and improving performance. The plastic parts of an automobile account for about 7% ~ 20% of its weight. For every decrease of 10%, the fuel consumption can be reduced by 6% ~ 8%.
In a word, petrochemical industry provides all kinds of daily necessities for human beings, enabling us to enjoy a comfortable and convenient high standard of life.
