The following are some ways to identify the quality of silica gel powder for mattresses:
Appearance inspection: High-quality silica gel powder is usually white or transparent and has a uniform texture.
If the silica gel powder has uneven particles, impurities, uneven colors, or obvious pollution, it may be a low-quality product.
Hand feel test: Take a small amount of silica gel powder and rub it gently with your hands. High-quality silica gel powder should feel smooth and soft, and should not feel granular.
If it feels rough or sticky, it may contain impure substances or processing problems.
Odor: Normal silica gel powder should have no obvious odor. If there is a pungent or other unpleasant odor, it may be due to the use of inferior raw materials or unqualified additives.
Density test: The density of silica gel powder is low, and high-quality silica gel powder should be light and loose. Low-quality silica gel powder may be compressed and deformed by hand pressure.
Hygroscopicity test: The hygroscopicity of silica gel powder is usually strong. You can gently touch the silica gel powder with a small piece of wet cloth. High-quality silica gel powder should be able to absorb moisture quickly and produce a certain degree of expansion. If the reaction is slow or not obvious, it means there may be quality problems.
Compare brands and manufacturers: Choose manufacturers or brands with high reputation and good reputation, and their product quality is usually guaranteed.
Check whether the manufacturer has relevant quality certification and test reports (such as SGS certification, etc.).
Ask professionals: If you are not sure about the quality, you can consult professionals in related fields or purchase samples for experimental testing to verify whether it meets the standards.
Through the above-mentioned tests, the quality of mattress silicone powder can be more effectively identified.
