commonly referred to as desiccants that is, moisture-proof desiccants, many people want to know desiccants What are they?

1. Silica gel desiccant

The main component is silicon dioxide, a highly active adsorption material made from purified natural minerals into granular or bead-like form. As a desiccant, its microporous structure (average 2A) has good affinity for water molecules. Silica gel is most suitable for humid environments at room temperature (20~32℃) and high humidity (60~90%). It can reduce the relative humidity of the environment to about 40%, therefore, Shandong Xinhua silica gel desiccants have a wide range of applications. At the same time, the chemical composition and physical structure of silica gel determine its irreplaceable characteristics compared to other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength;

2. Clay desiccant

The main component is montmorillonite, and the appearance is gray small balls. It is most suitable for moisture absorption in environments below 50℃. When the temperature is higher than 50℃, the degree of "water release" of clay is greater than the degree of "water absorption", but the advantage of clay is its low price;

3. Molecular sieve desiccant

It is an artificially synthesized desiccant product with strong adsorption capacity for water molecules. The pore size of the molecular sieve can be controlled by different processing technologies. In addition to adsorbing water vapor, it can also adsorb other gases, and it can still accommodate water molecules well at high temperatures above 230℃; Advantages: strong adaptability; Disadvantages: low moisture absorption rate, poor environmental protection;

4. Mineral desiccant

Hengyuan mineral desiccants is composed of several natural minerals, with a grayish-white appearance in small balls. It is non-toxic and harmless, and is a biodegradable and environmentally friendly desiccant with a moisture absorption rate of over 50%;

5. Fiber desiccant

Hengyuan fiber desiccants is made from pure natural plant fibers through special processes. Among them, the film-coated fiber desiccant sheet is convenient and practical, and does not take up space. Its moisture absorption capacity reaches 100% of its own weight, which is unmatched by ordinary desiccants. In addition, this product is safe and hygienic, and the price is moderate, making it an ideal choice for many biological, health food, and pharmaceutical products.
