Sodium carboxymethyl cellulose is a polymer with the following main characteristics:

Solubility: Sodium carboxymethyl cellulose has good solubility in water and forms a transparent solution.

Stability: Sodium carboxymethyl cellulose can still maintain good stability in both acidic and alkaline environments.

Swelling property: The solution of sodium carboxymethyl cellulose expands when heated, forming a gel state.

Sodium carboxymethyl cellulose is widely used in the following fields:

Pharmaceutical industry: Used for preparing binders and formers for tablets.

Petroleum drilling fluid: Used to improve the rheological properties of drilling fluid.

Environmental protection: Sodium carboxymethyl cellulose can be used as an additive for degradable plastics, enhancing the speed and effectiveness of plastic degradation.

The preparation method of sodium carboxymethyl cellulose can generally be obtained through carboxymethylation reaction. First, cellulose is reacted with chloroacetaldehyde or formaldehyde, and then after appropriate neutralization and washing treatments, sodium carboxymethyl cellulose is obtained.

Safety information: Sodium carboxymethyl cellulose is a relatively safe substance. However, the following matters still need to be noted during the usage process

Avoid contact with strong oxidants to prevent fire or explosion.

When in use, be careful to avoid inhaling dust or coming into contact with skin and eyes to prevent allergic or irritating reactions.

In case of accidental inhalation or contact, the affected area should be washed immediately and a doctor consulted.

When storing and handling, it should be kept sealed and kept away from fire sources and high-temperature environments. During use, necessary safety measures should be taken, such as wearing protective gloves, glasses and masks.
