When it comes to desiccant, I believe that many people will have little understanding, but in fact, desiccant can be seen everywhere in our lives, such as we are familiar with shoes and hats, clothing, food and other bags have their figure, it is a small bag of particles. Its existence is mainly to avoid moisture caused by water vapor problems.
What are the functions and uses of desiccant?
The so-called desiccant, in fact, is a moisture absorbent moisture-proof material, generally divided into two categories.
Chemical desiccants that are dried by combining with water to form hydrates, such as calcium chloride desiccants.
Physical desiccant, drying by physical adsorption of water, such as silica gel desiccant.
So why use these desiccants?
These desiccants are to better prevent the goods from getting damp and mildew, affecting the quality.
With the improvement of living standards, the types of desiccant on the market are becoming more and more diverse, and the characteristics of different desiccant such as moisture absorption rate are not the same, so that its scope of application is also different.
In order to let you more in-depth understanding of the characteristics of different desiccant and application range. Today to give you science!
Food desiccant
In daily life, many open food bags will put a bag of desiccant, and can be used in food desiccant there are two main kinds, one is a silica gel desiccant, one is a mineral desiccant.
Silica gel desiccant is based on silicon dioxide as raw material, will not soften or liquefaction, while using physical adsorption, but also has tasteless, no corrosion, stronger adsorption force, chemical stability and other characteristics. It can be in contact with food, and it is more secure and reliable to use it in food moisture-proof, and can effectively prevent all kinds of food from damp and mildew.
Industrial desiccant
In the industrial field, the application range of desiccant is also very wide, which can be used in the industrial field of desiccant are: silica gel desiccant, mineral desiccant, magnesium chloride desiccant, fiber desiccant, montmorillonite desiccant and so on.
Magnesium chloride desiccant is widely used in the field of electronic equipment, its main magnesium chloride as raw materials, its chemical properties are stable, absorption performance is balanced, therefore, is widely used in automotive headlights, automotive engines, daily hardware, security equipment, mechanical equipment and other equipment that needs moisture.
Montmorillonite desiccant is a degradable desiccant, mainly based on montmorillonite as raw material, is the physical way to adsorb water molecules in their own pore size, with fast adsorption speed, large adsorption capacity, non-corrosion and other characteristics. Widely used in electronic products, leather products, shoes and bags, crafts, clothing, cultural relics archives and other products.
Marine desiccant
Since calcium chloride desiccant is made of powder calcium chloride as raw material, it has active ingredients, high moisture absorption rate and fast moisture absorption rate, in addition, calcium chloride will form a gel when it reacts with moisture.
so it is used as a Marine desiccant. Because in the process of shipping, humidity is more serious, it is easy to form container rain, in this case, placing calcium chloride container desiccant is a cost-effective moisture-proof treatment.
The above is the characteristics of different desiccant and application range, we can choose the appropriate desiccant according to different product needs!
