The performance and application of zircon sand may be affected to some extent after it is wetted. The following is a concrete analysis:

I. Water absorption and the influence of moisture

Zircon sand itself has certain water absorption, and the water absorption rate is usually below 2%. When wet, its surface will absorb moisture, which may affect its performance in high temperature process.

In high temperature application, the absorbed water will evaporate during heating, which may lead to microcracks on the surface of zircon sand particles, and then affect its strength and fire resistance.

II. Impact on the process

Foundry technology: Moist zircon sand may cause surface quality problems of castings, such as sand sticking. This is because the evaporation of water at high temperature will destroy the structure of sand mold and reduce its fire resistance and permeability.

Refractory: The use of moist zircon sand in refractory may reduce the thermal shock resistance and service life of the material.

Chemical equipment: The wetted zircon sand may release water at high temperature, which will affect the thermal efficiency and service life of the equipment.

III. Suggestions for storage and disposal

Storage conditions: zircon sand should be stored in a dry and ventilated warehouse to avoid moisture and pollution.

Moisturizing treatment: If zircon sand is wetted, it is recommended to dry it before use to remove the moisture adsorbed on the surface.

Regular inspection: the quality of zircon sand should be inspected regularly during storage to ensure its stable performance.

IV. Matters needing attention in special applications

In some moisture-sensitive applications, such as precision casting or high-temperature refractories, zircon sand with low water absorption is recommended.

The influence of moisture on the properties of zircon sand can be reduced by controlling the processing parameters (such as temperature and humidity).

To sum up, the wetting of zircon sand may have a negative impact on its performance and application effect, especially in high temperature process. Therefore, moisture should be avoided as much as possible during storage and use, and appropriate drying measures should be taken.
