Silica Gel

• Introduction
• Silica gel desiccant is a high-end drying and hygroscopic material that is non-toxic, tasteless, odorless, chemically stable, and has It has strong hygroscopic properties and is a porous, highly active adsorption material. It is usually made by reacting sodium silicate with sulfuric acid. It is made through a series of processes including aging, acid soaking, washing, drying and screening.Silica gel desiccant has a three-dimensional spatial network structure, a highly active porous adsorption material, and a rich pore structure . It has a large specific surface area and is an amorphous substance with a transparent or translucent glass appearance. Silicon dioxide, the chemical formula is mSiO2 · nH2O , insoluble in water and any solvent , non-toxic and odorless, chemical The quality is stable and it does not react with any substance except strong alkali and hydrofluoric acid.Widely used in instruments, meters, equipment, leather, bags, shoes, textiles, food, medicine Control the relative humidity of the environment during storage and transportation to prevent items from moisture, mildew and rust.
• Safety performance
• ( 1 ) Silica gel has a strong adsorption capacity and has a drying effect on human skin.Therefore, the operation should wear work clothes. If silica gel gets into your eyes, rinse with plenty of water. If the situation is serious, seek medical treatment as soon as possible.
• ( 2)Silica gel is a neutral substance and will not react with any other substances except strong bases and acids under certain conditions. At the same time, silica gel is the only desiccant that has passed the FDA certification and can be used in direct contact with medicines and foodstuffs.
• ( 3 ) If silica gel desiccant is accidentally ingested, it generally does not cause harm to the human body and will not be absorbed by the human body. Drinking an appropriate amount of water will be excreted in the body’s feces.
• Package
• Packaging specifications: 25kg/ bag
• Size
• 2-4mm
• Use
• It is used for the articles or spaces that need moisture-proof and mold-proof, such as medicine, machinery, optical electronics, precision instruments, instruments, seeds, processed food, tea, all kinds of chemical fiber textile, leather shoes, leather, sports shoes, as well as cultural relics and archives, cameras, arts and crafts, and so on.
• （ 1 ) Silica gel desiccant is used for moisture-proofing of bottled medicine and food. Ensure that the items in the container are dry and prevent the growth of miscellaneous molds.
• ( 2 ) Silica gel desiccant is used as a general packaging desiccant. Such as bags, clothing, shoes , hats , leather, etc. Prevent goods from being affected by moisture during storage or transportation, which may affect product quality.
• ( 3 ) Silica gel desiccant is used in electronic products, instruments and meters, household appliances, mechanical equipment and other products to prevent goods from moisture affecting product quality.
• ( 4 ) Silica gel desiccant is used in transport containers to prevent items in the container from getting damp and affecting product quality.
• ( 5 ) The most suitable moisture absorption environment for silica gel desiccant is room temperature ( 20~32 ℃) and high temperature ( 60~90 ℃). Appropriate use can reduce the relative humidity of the environment to about 40% .
• Storage conditions
• Store in a dry place, the temperature of the storage environment 5-25 ℃, humidity below 70%, can not be placed in the light or radiation environment, airtight storage, not in direct contact with the air, the ideal state of the storage period of 10 years. Ideally, the storage period is 10 years. After opening, it should be used in time, and if not used up, it should be kept in a sealed place.
