How about celluloid, what is celluloid?

If you want to learn systematically, you can consider signing up for a live online class, and recommend CGWANG's online class. The teacher speaks carefully, you can watch it back after the class, and there are also the same type of recorded classes that you can learn for free (give away lifelong VIP).

In the training institutions in the field of "board painting, CG painting, impasto", [Wang's Education] is the leader in China, and it has not joined the branches, and it is a chain campus directly operated by the headquarters. Different from many other large institutions of the same type: each campus of Wang's Education is physically face-to-face, the teachers are hand-in-hand, and there are special class teachers from morning to night, and the liver-bursting learning mode will improve quickly, especially suitable for students with poor foundation.

Celluloid generally refers to celluloid. Celluloid refers to the old brand name used for plastic, and it is the earliest synthetic plastic produced commercially. It is a substance formed by nitrocotton and camphor after enhancing its plasticity.

Colorless and transparent, it can be used to make film films and imitation tortoiseshell, ivory, etc.

In the manufacturing process of early plastic products, many people exerted their ingenuity. Opaque and translucent celluloid flakes are staggered and crushed to create items that previously had to be made from ivory.

Replica tortoiseshell turtles are also a particularly popular item. It was only after many years that the natural properties of plastics were developed because of their own distinctive merits, and not because they imitated natural substances (or, as they are said, blemishes). Despite the proliferation of modern synthetic resins, nitrocellulose plastics are still used, and camphor is still the best plasticizer in the manufacturing process.

However, no celluloid can be durable enough for fine art use.

Celluloid, or nitrocellulose plastic, is a type of plastic that is processed from rubber wool (nitrocellulose with low nitrogen content) and plasticizers (mainly camphor), lubricants, dyes, etc. It is transparent, can be dyed in various colors, and is easy to burn. It is used to make toys, stationery, etc.

Formerly known as false ivory.

Celluloid was the main material used to make table tennis.

Celluloid is made of plastic. Celluloid is celluloid, which is the earliest synthetic plastic produced commercially, and is the ancestor of plastic, celluloid was discovered in 1846 by Schönbein of the University of Basel, Switzerland, when it was only used as a substitute for shellac.

Celluloid can be molded at the boiling point temperature of water, can be cut, drilled, or sawn at lower temperatures, and can be hard clumps or made into soft flakes.

Some celluloid pieces are flammable, celluloid jewelry can be damaged by moisture, extreme temperatures, or chemicals, and celluloid can be very sluggish or even crack when stored in a closed environment for long periods of time.

The most common use of celluloid is to make table tennis, ornaments, headwear, musical instrument decoration and picks, and also plays a role in many fields such as chemical industry, aviation reputation sitian, machinery, printing and dyeing, building materials, decoration, packaging, chemical grinding and makeup, gift packaging and so on.

Celluloid is made of plastic.

Celluloid refers to the old brand name used in plastic, which is the earliest synthetic plastic produced commercially, colorless and transparent, and can be used to make film films and imitate tortoiseshell, ivory, etc. In 1876, the inventor of celluloid marketed billiard balls and so-called imitation ivory products, made of cellulose nitrate and using camphor to increase plasticity.

Celluloid tends to be thinner and lighter than bakelite, and when heated to higher temperatures, it becomes brittle and can crack. Even some celluloid flakes are flammable and although more brittle than bakelite, it can still be bent or twisted. Under hot water, most celluloids have a taste like vinegar or old camphor.

Celluloid jewelry can be damaged by stuffy moisture, extreme temperatures, or chemicals. Celluloid stored in a confined environment for a long time can also be very sluggish and even crack.

Uses of 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 clump of hard ants, or it can be made into a soft sheet (which 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.

Its most common use is to make table tennis balls, ornaments, headgear, musical instrument decorations and picks. Other uses are in the chemical, aerospace, machinery, printing and dyeing, building materials, decoration, packaging, cosmetics, gift packaging and other fields.

Celluloid was one of the first man-made plastics to be introduced in 1865, and it softens when heated and hardens when cooled. After nitrification of part of the hydroxyl group (-OH) in cellulose, pyrolignin will be obtained, and then pyrolignin will be dissolved in a mixture of ethanol and ether, and then evaporated by adding camphor and so on.

The dramatic introduction of plastic from a treasure in a chemistry lab to the public eye was sparked by the dramatic introduction of plastic into the billiard room. In the past, billiards were made of ivory, and the ivory could only be used by dead elephants, and the number was naturally very limited. In the early 60s of the 19th century, someone offered a reward of $10,000 for the best substitute for billiards.

In 1869, the United States Hayert exploited"Celluloid"Cheap billiards were made, and the prize was won. Since then, celluloid has been used to make a variety of items, from children's toys to shirt collars. It was also used as a substrate for colloidal silver compounds, which was the first practical photographic negative.

However, due to the nitrate contained in celluloid, it is very easy to catch fire and cause disasters.

Celluloid is a synthetic material, also known as polyester resin. It is made by a polyester monomer that is perpolymerized. Polyester monomer is an organic compound whose molecule contains an ester group that can be esterified with another compound containing a hydroxyl group to form polyester.

Celluloid has excellent physical properties, such as high hardness, abrasion resistance, corrosion resistance, heat resistance, ultraviolet resistance, etc. It also has good processing properties and can be made into products of various shapes and sizes through various processes such as injection molding, extrusion, blow molding, calendering, etc.

Celluloid is widely used in home, construction, electronics, automobiles and other fields. In the field of home furnishing, celluloid can be made into a variety of furniture, tableware, kitchenware and other products, which have the advantages of beauty, durability and easy cleaning. In the field of construction, celluloid can be known and made into various decorative materials, pipe materials, etc., which have the advantages of fire resistance, corrosion resistance, and easy installation.

In the field of electronics, celluloid can be made into various electronic components, shells, etc., with the advantages of insulation and high temperature resistance. In the automotive field, celluloid can be made into auto parts, interior parts, etc., with the advantages of light weight, impact resistance, and ultraviolet protection.

In conclusion, celluloid is an excellent synthetic material with a wide range of application prospects.
