Shenzhen Chun Wang desiccant silica gel desiccant moisture 20g factory direct

Product Name: Shenzhen Chun Wang desiccant silica gel desiccant moisture 20g raw materials: excellent silicone, transparent, blue, orange three products specifications: 0.5g, 1g, 2g, 3g, 4g, 5g, 6g, 8g, 10g, 15g, 20g packaging materials: non-woven (. in Chinese, English, Japanese, French, German, Spanish print warnings, but also according to customer requirements) Product Overview: silica gel desiccant is a highly active adsorption material, usually sodium silicate and sulfuric acid and after aging, acid bulbs and other physical processes in the system, belong to the amorphous material, its chemical formula is mSiO2.nH2O. in line with China's chemical standards HG / T2765-2005. Is the only FDA-approved desiccant can be in direct contact with food and drug. Where: transparent silicone colors maintain moisture absorption (but long-term placement in colored air environment, the air, including colored molecules attached, will be dyed). Blue and orange silicone, can also play a role usually display agent after blue silicone to absorb moisture, red, orange silica gel after absorbing moisture, become green. Core strengths: 1, effective absorption of more than 30% of its own weight of water 2, do not change their form, non-toxic, harmless after absorbing moisture, pollution 3, good thermal stability, strong mechanical strength 4, widely used, footwear, leather, handbags, food, pharmaceutical, metal toys, wood products, instrumentation, electronic appliances, etc. can use disadvantages: montmorillonite, live ore and other mineral desiccant, its cost is higher non-woven bag Material Features: 1, breathable very good, good fastness 2, size specifications can be packed in 3, affordable product is a simple self-test method failed product weight flexibly adjusted according to the thickness of the packaging material: 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.
