Introduction

Product introduction
    Silica gel desiccant is a kind of silica gel with different kinds of hygroscopic bags. The main raw material silica gel is a high porous structure of water silica, non-toxic, tasteless, odorless, and highly active chemical adsorption material, with strong hygroscopic performance. Therefore, it is widely used for controlling relative humidity in storage and transportation of instruments, instruments, equipment, leather, bags, shoes, textiles, foodstuffs, medicines and so on, preventing moisture dampness, mildew and rust. Silica gel desiccant is a highly active adsorption material, which is usually prepared by the reaction of sodium silicate with sulfuric acid and after a series of post-processing processes, such as aging, acid bubble and so on. Silica gel is an amorphous substance with a chemical molecular formula of mSiO2.nH2o. Insoluble in water and any solvent, non-toxic and tasteless, chemical property is stable, except for strong alkali, hydrofluoric acid and no reaction with any substance. The chemical composition and physical structure of silica gel determine that it has many other characteristics that are difficult to replace by other similar materials: high adsorption properties, good thermal stability, stable chemical properties, and high mechanical strength. The inside of silica gel desiccant is a tiny pore mesh structure, which can absorb moisture and retain moisture through its physical attraction, such as aviation components, computer devices, electronic products, leather products, medicine, food and other industries. Even if the desiccant is immersed in the water, it will not soften or liquefy. It has the characteristics of non-toxic, tasteless, non corrosive and pollution-free, so it can be directly contacted with any item.
Product advantage
    Silica gel desiccant safety performance: silica gel has a strong adsorption capacity, can produce dry skin effect on human skin, therefore, should wear good work clothes. If silica gel enters the eye, it needs a lot of water to wash and find the doctor for treatment as soon as possible. Active mineral desiccant, also called attapulgite drier, is made from pure natural mineral and active moisture absorbent. It is green, non-toxic, tasteless and harmless to human body. The products have good adsorption properties at room temperature and general humidity, which have the effect of adsorption activity, static dehumidification and odor removal. It can be widely applied to products that cannot be sealed by oil or gas phase, such as optical instruments, electronic products, medical health care, food packaging, dry air seal of military products and civilian products.
    Silica gel desiccant is widely used in hardware, lighting, bags, leather goods, footwear, food, environmental control storage and transportation of electronic products, household appliances, handicrafts, instruments, clothing, footwear and other products in the relative humidity, prevent moisture, mildew or rust and other items. The inside of silica gel desiccant is a tiny pore mesh structure, which can absorb moisture and retain moisture through its physical attraction, such as aviation components, computer devices, electronic products, leather products, medicine, food and other industries. Even if the desiccant is immersed in the water, it will not soften or liquefy. It has the characteristics of non-toxic, tasteless, non corrosive and pollution-free, so it can be directly contacted with any item.
technical parameter
Quality index of silica gel desiccant
Quality index conforms to HG/T2765-2005
The unit adsorption capacity: adsorption amount of RH=20% is more than 10% RH=40% = 20% RH=90% = 30%
Note: according to the standard of GB10455-89: RH = 90% = 28% = 29% first grade qualified excellent products is more than 30%
