Moisture Absorption Principle of Hygroscopic Agent

2022 11/25

A variety of additives are used in the combination of rubber and plastic. The moisture contained in these additives or the gas inhaled during the mixing process will cause problems such as bubbles, surface defects, and dimensional instability. This product, Hygroscopic Agent Masterbatch For Rubber, is properly blended to completely remove moisture or gas from the raw material compound, and a drug developed to obtain an excellent product without bubbles is called an anti-bubble agent or a hygroscopic agent. Using this product Masterbatch Hygroscopic Agent can reduce costs, improve quality and reduce bad effects.

Solid Hygroscopic Agent: Utilizes a porous substance with a large surface area to absorb moisture from the air under surface adsorption and capillary condensation. Since the partial pressure of water vapor on the surface of the solid hygroscopic agent is lower than the partial pressure of water vapor in the air, it absorbs the moisture in the air and achieves the purpose of air dehumidification.

Liquid Hygroscopic Agent: Use the liquid hygroscopic agent with strong hygroscopic and hygroscopic ability to directly treat the air. When the liquid hygroscopic agent is in direct contact with the moist air, the driving force is the partial pressure of the water vapor in the air and the saturated vapor on the surface of the liquid hygroscopic agent. The pressure difference can be achieved to achieve the effect of air dehumidification.

Gas Hygroscopic Agent: The process of mixing two kinds of air with different humidity (dry air and moist air) to exchange heat and mass, so as to realize the effect of moist air dilution and dehumidification.
