Guangdong Shenzhen Chun Wang environmental desiccant 5g, factory direct moisture absorbent

Guangdong Shenzhen Chun Wang environmental desiccant 5g, factory direct moisture absorbent Description: Silicone is a highly active adsorption material, usually sodium silicate and sulfuric acid and by the aging, acid bulbs and other physical processes in the system, the case of amorphous silica state of matter, its chemical formula is mSiO2.nH2O, stable chemical properties, in addition to alkali, hydrofluoric acid does not react with any substance, chemical composition and physical structure of silica determines that it has many of the characteristics of the material is difficult to replace: adsorption high performance, good thermal stability, high mechanical strength, non-toxic, tasteless, non-polluting. Product quality standards in line with China's chemical standard HG / T 2765.1-2005 and Chinese military standard GJB 2714-2005. Blue Silicone adds about 3 ‰ -5 ‰ cobalt chloride, orange silica gel containing 0.9 ‰ methyl violet (environmental) performance parameters: size passing rate of> 86% of the bulk density of> 750g / L of water adsorption T = 25 ℃, RH = 80% ≥30% moisture content ≤5% PH value 4-7 refer to the amount of about 1 liter packing space with 1.67 g -2 g core strengths: 1, effective absorption of more than 30% of its own weight of water 2, do not change after moisture absorption own form, non-toxic, harmless, non-polluting 3, good thermal stability, strong mechanical strength 4, versatile, footwear, leather, handbags, food, medicine, metal toys, wood products, instrumentation, electronic appliances etc. can be used Disadvantage: Compared montmorillonite, live ore and other mineral desiccant, its cost is higher composite wrap material characteristics: 1, the printing clear, easy to identify warning 2, permeability general fastness generally 3 , a strong price advantage is a simple self-test failure: 1, the desiccant bags tear, take silicone material clasped hands, to see if there is heat, cooling then the silica gel also effective. 2, if you added blue plastic, orange gel indicator indicating gum discolored, indicating silica gel has expired. 3, Sheng small cup of cold water, tear desiccant bag, the raw material is poured into water to see if silica grains will blown to pieces, and the issue of "Cha Cha" sound, yes, it is effective. 4, take the desiccant pouch, said good weight, good mark, placed indoors, every 5-10 days and then weighed to see if there will be increase in weight, an increase in the effective. 5. For more precise performance desiccant to absorb moisture, required equipment testing laboratory. Widely used in footwear, handbags, food, medicine, toys, wood products, equipment, instruments, electronics, computers, furniture and other items of packaging seal, static adsorption confined space, to remove moisture, control of relative humidity, moisture-proof anti- mold effect. dehumidification bags _11
