Our commonly used china Silica Gel Desiccant is mainly divided into two categories: coarse-pored spherical silica gel and fine-pored spherical silica gel. And these two kinds of china Silica Gel Desiccant also have their own characteristics, among which the fine-pored spherical silica gel is characterized by a stronger hygroscopic ability than the coarse-pored spherical silica gel in the case of low relative humidity. This knowledge of these two kinds of china Silica Gel Desiccant is relatively speaking, in fact, these two kinds of moisture-proof desiccants are commonly used in packaging.

In the sealing and packaging of products, a large amount of fine-pored silica gel is used as a desiccant. Fine-pored china Silica Gel Desiccant should go through five procedures including unpacking, inspection, cleaning, drying, packaging and sealing during the entire product packaging process. In the packaging and sealing process, fine-pored silica gel is generally used as a desiccant.
The specific method is: wrap the dried equipment with neutral paraffin paper and cow (sheep) vellum paper, put it into a plastic composite film envelope, and put an appropriate amount of fine-pored silica gel and humidity indicator on both sides of the inside of the envelope. The vacuum pump draws out the air in the envelope, seals the mouth of the envelope with a heat sealer, and completes the sealing and packaging. The function of fine-pored silica gel is to absorb excess water in the sealed envelope and prevent the equipment from rusting. The change of humidity inside the envelope is reflected by the color of the humidity indicator. If the silicone indicator shows that the humidity inside the envelope is too high, it should be resealed.
The china Silica Gel Desiccant Usage Calculation Method When using silica gel as a desiccant in the sealing and packaging of aviation materials, the usage amount should be accurately calculated according to the volume of the package, packaging container, storage period, storage environment, etc., to ensure long-term drying effect. It is difficult to establish an accurate calculation formula for the dosage of china Silica Gel Desiccant according to the sealed container. In the practice of using desiccant at home and abroad, people are based on specific conditions and from different angles. Based on different needs, a relatively applicable calculation method is established. Purpose When placing the desiccant, we adhere to the principle of preferring more than less. Less will cause the product to be damp, and if there is too much desiccant, it will not affect the product.
