Moisture has a significant impact on the quality of production equipment and products, causing various losses in storage. However, people have a weak awareness of this issue, coupled with excessive control over management costs, and have not taken action to address the effects caused by moisture, ultimately resulting in even more serious losses.

With the rapid development of society and the advancement of technology, people's demands for product quality are becoming increasingly higher. Whether it is due to the improvement of customer requirements or the enhancement of the factory's own quality standards, the humidity control in the storage process has become increasingly strict. Excessive humidity can easily cause the following problems, resulting in poor quality, rusting and damage, etc., causing serious economic losses. Therefore, it is necessary for managers to pay close attention to it.

Steel does not easily rust when the relative humidity is below 50%. The shelves in large warehouses are usually constructed of steel, which is more susceptible to moisture, leading to problems such as rusting and aging.

Dehumidifiers are widely used in the chemical industry because many areas in this field require dehumidifiers to control humidity. During the production of polyethylene, the humidity of ethylene raw gas needs to be detected. Water can poison the platinum catalyst, and only by controlling the appropriate humidity of the gas CO2 can the production proceed smoothly. In the production process of chlorine compounds such as bleach, the humidity value of the carrier gas must be strictly controlled; otherwise, it will react with water to form waste acid. In the production process of compressed gases, pre-dehumidification of the gas is necessary to prevent the condensation of saturated water vapor during compression; for liquefied gases, adequate dehumidification of the gas is required to prevent water vapor condensation from causing blockages in valves and components; in the production and storage of liquid SO2, if the moisture is not adequately dehumidified, SO2 reacting with water can form corrosive sulfurous acid and sulfuric acid; in the transportation and storage of natural gas and liquefied petroleum gas, when the moisture content in the gas is too high, it will freeze at temperatures below 0 ℃ and form solid hydrates at temperatures above 0 ℃; in the polymerization process of nylon and polyester and the textile process of fibers, poor humidity control will reduce production efficiency and affect product quality.
