Importance of humidity control

The moisture imposes great impact on production equipment and product quality and causes various losses to storages. However, people have little awareness of this. In addition, the handling cost is overcontrolled. Therefore, no action has been taken to solve the impact of moisture. Finally, more serious losses are caused. Exposed in an environment with high RH, the materials stored are highly susceptible to damages. Generally, if the RH in a storage space exceeds 55-60%, problems will occur. If there is condensate water on materials, the damage may be faster.

The steel is not easy to rust if the RH is below 50%. Large storage shelves are made of steel, thus such shelves are susceptible to moisture, causing rusting, aging and other problems. The materials stored in environment with an RH higher than 60%, such as food, medicine, leather, furniture, electronic products, chemical raw materials, hardware appliances, printing product and tobacco, are easy to absorb moisture and cause corrosion, short circuit, deformation, mildew and other phenomena. Therefore, the humidity should be properly controlled to ensure the quality, extend the shelf life, lower defective rate and loss and protect assets from losses.
