Collodion is a flammable, syrupy solution of nitrocellulose in ether and alcohol. There are two basic types: flexible and non-flexible. The flexible type is often used as a surgical dressing or to hold dressings in place. When painted on the skin, collodion dries to form a flexible nitrocellulose film.
The principal uses of cellulose nitrate is for the production of lacquers and coatings, explosives, and celluloid. [6]In terms of lacquers and coatings, nitrocellulose dissolves readily in organic solvents, which upon evaporation leave a colorless, transparent, flexible film. [4]
Celluloids are a class of materials produced by mixing nitrocellulose and camphor, often with added dyes and other agents.Once much more common for its use as photographic film before the advent of safer methods, celluloid's common present-day uses are for manufacturing table tennis balls, musical instruments, combs, office equipment, fountain pen bodies, and guitar picks.
The first practical nitrocellulose enamel Glossy White S.2567, still for interior use, was introduced in 1919 in the UK by Nobel Explosives. [26] In 1923, General Motors' Oakland brand automobile was the first to introduce one of the new fast-drying nitrocellulose lacquers, a bright blue, produced by DuPont under their Duco tradename.
All have been used separately and in mixtures, to produce film base. Despite the dangers of the nitrate film base being known practically since its development, it was used in virtually all major motion pictures prior to 1952, when Kodak completed a four-year conversion program to the sole manufacturing of acetate base film stocks. Kodak began ...
It turns out, the Tepezcohuite tree's bark has been used to regenerate skin and hair in Mexico for decades, including hundreds of thousands of burn victims involved in an earthquake and a gas ...
It is inherently more stable than both cellulose nitrate and cellulose acetate, because it is a synthetic polymer that is inert (chemically inactive). It shows exceptional chemical stability and physical performance. [1] A polarization test can be used to identify polyester from cellulose acetate or nitrate. When viewed between cross-polarized ...
Cellulose is the most abundant organic polymer on Earth. [6] The cellulose content of cotton fibre is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. [7] [8] [9] Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and ...
