Find the chemical composition of table tennis cell celluloid chemical name, chemical formula, chemic

The Chinese name is: (nitrocellulose plastic) This is a mixture without a chemical formula.

Combustion produces toxic gases such as nitrogen oxide. Oxygen-free automatic decomposition produces carbon monoxide, methane, hydrogen, nitric oxide, nitrogen dioxide and cyanide hydrogen acid and other flammable and explosive highly toxic gases.

Celluloid is an indispensable ingredient in the manufacture of table tennis balls, spectacle frames, accordion housings, etc. It consists of nitrocellulose (74%), camphor (24%), ethanol and water (2%). Its spontaneous ignition point is 180 and the ignition point is 125, producing a high temperature of 1300-1500.

Insoluble in water, benzene, toluene, soluble in ethanol, acetone, ethyl acetate.

Answer first, carbon fiber material. The chemical composition of carbon fiber is "polypropylene cyano carbon material", which is a composite material formed by the reaction of carbon fiber and matrix resin, and its physical properties such as strength and specific elasticity can be comparable to metal, but the weight is much lighter. Therefore, this material is used to make a highly elastic table tennis bottom plate, which is characterized by light weight, high force, low and flat hitting arc, and fast speed.

Second, aryl fibers. Aryl fiber, also known as aramid fiber, is often used as a material for body armor in the military, and is a new type of highly flexible material. The baseplate made of this type of material can maintain high flexibility and elasticity, which can not only ensure that the table tennis player can make enough spin, but also enable the player to play a long enough arc to meet the needs of the curve ball attack technique.

Third, fiberglass. Glass fiber is an inorganic non-metallic material with excellent properties. The ingredients are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., which are made of glass balls or waste glass as raw materials through high-temperature melting, wire drawing, winding, weaving and other processes to finally form various products.

This is a more common material, its strength is not as good as carbon fiber, toughness is not as good as aryl fiber, but in terms of its cost performance is the highest, can bring good performance at a low price.

The ball used in table tennis, made of celluloid, is four centimeters in diameter.

Table tennis originated in England at the end of the 19th century and is said to have originated in tennis. Legend has it that several college students used the table as a court and pushed the wine bottle stoppers around the table with wooden boards like playing tennis, so it was called "table tennis", which is the origin of the English "table tennis" of table tennis. Around 1900, due to the development of light industry, the ball was changed to a hollow ball made of celluloid.

Hewitt, a printer in New York, concocted an artificial plastic that looked like ivory, softened by heat and hardened by cold, and named it celluloid, and in 1869 Hewitt used celluloid to make a batch of table tennis balls, which was very popular with people. Nowadays, table tennis balls are mostly processed from plastic made of cotton.

celluloid, which is a plastic made of rubber wool (nitrocellulose with low nitrogen content) and plasticizers (mainly camphor), lubricants, dyes, etc. Keratin, transparent and tough. Thermoplastic, softened at 80 90.

It is resistant to water, dilute acid, weak alkali, salt solution, hydrocarbons, oils, etc. However, concentrated acids, strong alkalis, and many organic solvents can dissolve or destroy them. Easy to catch fire.

Table tennis is made by celluloid.

The uses of celluloid are varied and extend far beyond the pool table. It is capable of molding at the boiling point temperature of water; It can be cut, drilled, or sawn at lower temperatures; It can be a hard clump or made into a soft sheet (it can be used to make shirt collars, children's toys, etc.). Thinner and tougher sheets could be used as substrates for colloidal silver compounds, making it the first practical photographic negative.

Now its most common use is to make table tennis, other uses are in the chemical industry, aerospace, machinery, printing and dyeing, etc.

The table tennis ball is made of a material called "celluloid".

Celluloid nitrate is the name given to a synthetic resin, the oldest thermoplastic resin in history, synthesized from raw materials such as nitrocellulose and camphor. Typical products include table tennis balls and dolls.

Because it can be easily formed, it was developed as a substitute for ivory. The disadvantage is that it is extremely flammable and has the durability to easily ignite after friction, so it is rarely used now, but this material is still used in table tennis balls.

Standard table tennis balls are made of a material called celluloid. Celluloid is flammable and has certain requirements for storage.

Cellulose nitrate (commonly known as nitrocellulose), the cellulose nitrate with high nitrogen content is called fire cotton in industry, and the cellulose nitrate with nitrogen content is called rubber wool. Rubber wool can be used to make cellulo, which is the material for table tennis balls.

A lot, we often hit plastic!

Because the table tennis ball is made of chemical materials, it contains benzene. Camphor has benzene.

The taste of plastic, put it for a few more days, it is estimated that it is a relatively poor table tennis ball made of plastic.

Celluloid has the advantages of light weight, good elasticity, and relatively durable, so it has always been used. However, the ITTF has passed a resolution that from July 1, 2014, major international competitions, including the ITTF Open and Finals, will use new material table tennis. At the same time, the ITTF also gave a two-year transition period, until the end of June 2016, celluloid and new plastic balls can be legally sold on the market at the same time, from July 1, 2016, the celluloid FITF will no longer be recognized, which means that celluloid ball, which has a history of more than 120 years, will be completely withdrawn from the stage of history.

Celluloid is a nitrocellulose plastic, which is elastic and flexible, and is very suitable for table tennis rackets. I haven't thought much about any new materials. So it's been used until now.

On May 9, 2014, table tennis balls made of green cellulose acetate were released worldwide, which means that celluloid, a flammable material that has been used to make table tennis balls, has been withdrawn from the stage of history.

1. Table tennis floors are divided into two categories: pure wood and carbon plates. It is necessary to choose the right base plate according to the playing style, technical ability and economic conditions.

2. Extended introduction.

1) Single plank, is a whole piece of wood, only single cypress and single ayous two kinds, single plank is very violent, but basically the thickness of the double-sided will exceed the standard, and it is heavier, South Korea and Japan are more famous for their single cypress There are many players, such as Yoo Seungmin.

2) Five clips of pure wood, it is heavier than eating the ball deep, creating an arc circle, to the opponent's table to rotate to cause two jumps to accelerate. Five-clamp pure wood is the most widely used.

3) Seven clips of pure wood, with the characteristics of fast speed and great strength, suitable for fast attack near the platform and retreat from the middle of the platform.

4) Carbon bottom plate, carbon bottom plate is not the whole ball board is carbon, but the carbon layer is added to the wood interlayer, or toner is added to the glue when the wood is bonded. The carbon base plate is very elastic and has more strength than a pure wood base plate with the same structure without carbon. However, the carbon bottom plate has the characteristics of poor feel and weak control, especially when it does not exert force, it is almost the same as when it is forced, it plays very strongly, and the small ball in the table is particularly at a loss, and it is usually used by amateurs to make up for the lack of physical strength.

5) Fiberboard, fiberboard is a combination of the rotation of pure wood board and the speed of carbon board, usually used as a fast speed and strong arc ball play.

The fiber materials that have been used to make composite fiber base plates include carbon fiber, aryl fiber and glass fiber, etc., and their common feature is that they can improve the hitting efficiency of the base plate, and are commonly used composite materials for making table tennis bottom plates.

On the first floor, there are several common fibers used in the bottom plate, such as carbon aryl and glass fiber, but now the glass fiber has been eliminated, and the high performance is not good The fiber is only an auxiliary material in the production of the bottom plate, and now there are many new fibers that are used in the production of the base plate, such as the ZL fiber used by the butterfly, the new fiber of Shiaode and so on.

The main ingredient is wood: commonly used woods are ayous, lympha, paulownia, cypress, etc., as well as basha, walnut, and even bamboo. People are exploring new woods and hope to have more options in the making of baseboards.

The kind I played in elementary school was plastic + rubber.

I guess it's rubber.,Hoo should be it = =、

The material used to make table tennis balls is called celluloid, which is composed of nitrocellulose (74%), camphor (24%), ethanol and water (2%). What you smell is the smell of camphor. It is a dangerous goods and must be packed in corrugated boxes.
