Do you want to know the use of silicone?

When it comes to silicone, many people are confused. "I only heard of Silicon Valley related to silicon, and I know that silicon will be used in computers. I really haven't heard of it." maybe most people outside the industry will react like this when they hear about silicone.

It is true that silicone is not as well known as plastics, metals and other materials, but in our life, it is as widely used as other materials and products.

Today, let's not talk about chemical formula and technology, but talk about silicone in our production and life.

Military use

In other words, the exploration and research of organosilicon compounds can be traced back to the 18th century. However, the rapid development of organosilicon was due to its use as a special material for military equipment such as aircraft, rockets and tanks during the Second World War. Silicone material is a typical semi inorganic and semi organic polymer material. It has unique properties of high and low temperature resistance, oxygen resistance, light resistance and weather aging resistance. Therefore, it is widely used in aircraft structure screw connection, resistor, surface sealing of radio electronic equipment, etc.

That's not intuitive enough. Let's take an example. When the tanks and tanks of the two countries were frozen in winter, all the equipment needed by the Soviet Union was frozen. In the face of this grim situation, Soviet scientists found that a substance mixed with oil can prevent freezing, thus gaining an advantage in the war against Germany. This material is what we call silicone oil today.

Aerospace

"It's just a small step for me alone, but a big step for mankind as a whole." With the success of the U.S. landing on the moon in 1969, American astronaut Armstrong left his first footprints on the surface of the moon. The sole material of the boots he was wearing was silicone rubber produced by Dow Corning company!

Of course, today, silicone materials are more widely used in aerospace, instrument oil, damping oil, special hydraulic oil, advanced coating and so on are inseparable from silicone materials.

Just as many science and technology products are due to military war and popular in life, so are silicone materials! Due to its excellent performance, silicone materials have been rapidly used in all aspects of production and life after World War II! It can be said that from we open glasses in the morning to go to bed at night, we will deal with silicone products all day.

Cosmetics

Silicone used in cosmetics was first used in 1950 by Dow Corning company. Today, organosilicon has been successfully applied to perfume, wax, conditioner, lipstick, shaving cream, removing sweat, eye shadow, nail polish and sunscreen.

In the morning shower, shampoo and conditioner contain silicone oil to make our hair smoother. The silicone oil applied to the skin cream on the face can cover a very thin veil on the skin of the face, so as to maintain the moisture and protect the skin. The oily foundation, nail polish, sunscreen and eye shadow paste contain two methyl siloxane. There was no residue.

In recent years, the application of silicone in daily chemical industry has developed rapidly, and has become one of the main silicone applications. Almost all personal care products contain siloxane components, and with the advent of new products, this kind of functional raw materials has been expanding its application field. Siloxanes are increasingly being used to replace some or all of the useful ingredients of organic raw materials in cosmetics and cleaning products due to their easily adjustable functional properties and excellent sensory properties, as well as the benefits of environmental and consumer safety.

Textile printing and dyeing

After a bath to wipe the body towel, we wear clothes and other textiles are also inseparable from silicone materials.

Polydimethylsiloxane, as the first organic silicon for printing and dyeing auxiliaries, greatly improves the washing resistance of clothes; hydroxyl polysiloxane improves the wrinkle resistance of clothes; polyether modified silicone improves the antistatic ability of fabrics. Fluorine modified silicone softener has the effect of deepening fabric dyeing!

Therefore, soft towel, smooth shirt, anti-static clothes and so on all depend on the strong performance of silicone materials.

Diet

After washing, have a nice breakfast. If you think food and drink should have nothing to do with silicone, you are wrong.

A friend who goes to eat barbecue must be familiar with the oil paper on the electric stove. Why can a piece of paper be baked on such a high temperature stove is because it is coated with silicone resin, which is non stick, waterproof, oil proof and high heat resistance (230 ℃).

When you go to the bakery to buy bread, you will put a layer of paper on the plate, which is coated with food grade silicone oil to effectively prevent adhesion.

For the baby feeding bottle, the nipple is silicone rubber, and the baby spoon is also food grade silica gel. In addition, there are many aspects of the diet will use silicone materials.

Automobile

After washing and breakfast, we drove to work. Of course, as one of the main modern means of transportation, the automobile is the place where silicone materials are used.

Silicone rubber with better air tightness and chemical resistance can be made into car lamps
