How to distinguish the real silica gel?
Jun 10, 2018

How to tell the truth from the silica gel? From feel respect, silica gel products are good elasticity and tenacity, it is not easy to permanent deformation due to external force, and touch feel is smooth, the fake of silica gel products easy to deformation, and the touch is rough, because the fake of the surface of the silica gel material without a grease; From the aspects of characteristics, silica gel products are non-toxic tasteless colorless product, good quality of a material, no harm to human body, and generally counterfeit products it is difficult to achieve the effect of silicon, fake and inferior products of silicon are generally have pungent odor, poisonous and also more rough. At the same time, we can burn the real silica gel through the flame...

What kind of authentication is required for the authenticity of silica gel? Food grade silica gel is made from silicate polycondensation of inorganic polymer gel material, ingredient is SiO2 · nH2O, its content is over 98%, avirulent insipidity, stable chemical performance, under the normal except hydrofluoric acid and caustic, not any response from the acid and alkali salt. Currently on the market infant products involves the silicone material, are divided into pharmaceutical grade silica gel and food-grade silicone, a higher standard of pharmaceutical grade silica gel, are required to pass through the state food and drug administration certification. China's infant and infant products on the market generally follow three national standards: China, the United States and South Korea. No matter what kind of national standards the product is subject to, it can only be certified by the national food and drug administration to be authentic. Be sure to read when you buy.

Because edible silica gel is refined and sterilized, it can be mixed with food and drug as required, and directly guarantee the food to be dry and eaten with food, without any toxic and side effects on human body. Therefore, pay attention to the entrance security parents towards silicone materials infant products, and the infant products has a lot to latex, rubber as the phenomenon of silica gel, even in the industry to carefully distinguish to distinguish true and false.

Professionals tend to through the following three recruit to identify the authenticity of a silica gel: try: elastic rubber, latex has good elasticity, silica gel is fragile, when selected, you can try the elasticity, if the elastic is very good, there may be a rubber; See color: rubber, latex because impurity content is much, cannot make transparent color product, and silica gel is colorless transparent, want to make transparent silicon rubber product must be with silica gel material; Smell flavor: rubber, latex product flavor is thicker, smell can smell acrid smell, some manufacturers to cover up flavor and increase fragrance, so choose silica gel material material will be much better. Silica gel for process itself is relatively complex, so the price not the cheapest, identify the authenticity of a silica gel method has told you, so when the choose and buy don't buy because take advantage of low price of silica gel products.
