Shape: White (yellowish) spherical crystal.

Performance: as the microporous structure of desiccant, it has good affinity for water molecules. The most suitable hygroscopic environment for silica gel is room temperature (20-30) and high temperature (60-90%), which can reduce the relative humidity of the environment to about 40%. It is applicable to control relative humidity for the purpose of moisture-proof in the process of moisture-proof, rust proof and sea transportation.

■ Application: it is commonly used in medicine, food, precision instrument and other articles to absorb water molecules in relative space, with good compatibility and chemical stability。

Application: commonly used in precision instruments, camera lens, food shelf life, etc,As a visual inspection of the microscopic changes of the goods within the shelf life.

Storage conditions: when the products are packed in cartons or containers, the humidity shall be kept below 70% RH and the temperature shall be kept around 40 ℃ in a clean and dry warehouse. The shelf life of silica gel desiccant shall be 18-24 months to avoid moisture and mixing with volatile substances.

■ Packaging materials: tea filter paper, composite paper, DuPont paper, three in one paper, non-woven fabric, OPP plastic film, Anilox paper.

■ Production capacity: we can produce all kinds of sizes according to customers' requirements.

Reference value of small package dosage of silica gel desiccant:
（1）  Silica gel desiccant needs to absorb water molecules in a certain space. The moisture absorption rate is relative, not absolute.
The amount of desiccant depends on many factors: the amount of drying space, the material of packaging materials, and the storage environmentAnd shelf life。
（2）  Dosage reference value: outer packing material—Cartons and inner packaging are bottled—Capsules or tablets
