X-Ray film base - Introduction
Cellulose triacetate (also known as cellulose acetate or cellulose triacetate) is an important cellulose derivative. Its chemical structure is formed by the substitution of hydroxyl groups of cellulose by acetate groups. The following is a description of the properties, uses, methods and safety information of cellulose triacetate, solvents, auxiliaries and polyesters:
Nature:
-Cellulose triacetate is a solid, usually white or slightly yellow.
-It has a certain degree of plasticity at room temperature.
-has the characteristics of chemical stability, solubility, high strength and high modulus.
-Under hot and humid conditions, cellulose triacetate will decompose.
Use:
-Cellulose triacetate is widely used in the manufacture of cellulose fibers, such as textiles, paper, membrane materials, etc.
-It has excellent flexibility and plasticity, and can be used in the textile and fiber products industry.
-Cellulose triacetate can also be used as a carrier in drug delivery systems such as pharmaceutical coatings and capsules.
Preparation Method:
-The preparation of cellulose triacetate usually uses chemical synthesis methods.
-A common preparation method is to react cellulose with acetic anhydride in the presence of a strong acid catalyst to form cellulose triacetate.
Safety Information:
-During use and storage, care should be taken to prevent cellulose triacetate from contacting the skin, eyes and respiratory tract.
-Avoid swallowing or prolonged exposure to high temperatures to prevent potential hazards.
-Use appropriate personal protective equipment such as gloves, glasses and breathing apparatus when handling cellulose triacetate.
-Follow proper operating procedures and safety signs and comply with local codes and regulations.
