Product Description:

physical property

Appearance: Usually white to milky white powder, odorless or slightly odorless, tasteless.

Solubility: It has good solubility and can dissolve in various organic solvents such as water, ethanol, chloroform, etc. It can form a clear and transparent solution in water.

Moisture absorption: It has a certain degree of moisture absorption and is easy to absorb moisture from the air in environments with high relative humidity.

Viscosity: Its aqueous solution has a certain viscosity, which can play a role in thickening, bonding, etc.

chemical PROPERTIES

Stability: The chemical properties are relatively stable at room temperature and pressure, and it is not easy to undergo chemical reactions such as decomposition and oxidation. But under extreme conditions such as high temperature, strong acid, and strong alkali, degradation or other chemical reactions may occur.

Complexation: The molecular structure contains lactam groups, which can form complexes with many substances, such as iodine, phenols, etc., thereby changing the properties of these substances, such as increasing the water solubility and stability of iodine.

Chemical reactivity: Due to the presence of active groups such as double bonds in its molecular structure, chemical reactions such as polymerization and cross-linking can occur under certain conditions.

Transportation precautions

Packaging requirements

Moisture resistant packaging: Due to its strong moisture absorption, well sealed packaging materials such as cardboard or iron drums lined with plastic bags should be used to prevent moisture absorption and agglomeration during transportation, which may affect product quality.

Packaging strength: The packaging should have sufficient strength to withstand external forces such as collision and compression during transportation, preventing packaging damage and product leakage.

Temperature and humidity control

Temperature: During transportation, high temperature environments should be avoided, and the temperature should generally be controlled below 30 ℃ to prevent product degradation or other adverse reactions due to high temperatures.

Humidity: The transportation environment should be kept as dry as possible, and the relative humidity should be controlled below 60%. An appropriate amount of desiccant, such as silica gel, can be placed in the transportation container to absorb moisture from the air.

Isolation from other goods

Avoid mixing: Polyvinylpyrrolidone PVP and polyvinylpyrrolidone K30 should be avoided from being mixed and transported with strong oxidants, strong acids, strong bases, and other substances to prevent chemical reactions that may cause product deterioration or safety hazards.

Isolation distance: A certain isolation distance should be maintained from goods that may cause pollution or mutual influence, and it is generally recommended that the isolation distance be no less than 1 meter.

Loading and unloading operations

Handle with care: During loading and unloading, pay attention to handling with care, avoid rough handling, and prevent packaging damage. Use appropriate loading and unloading equipment, such as forklifts, cranes, etc., to ensure smooth loading and unloading of goods.

Prevent spillage: During loading and unloading, attention should be paid to preventing product spillage. If spillage occurs, it should be cleaned up in a timely manner to avoid mixing the product with other substances or polluting the environment.
