The main appearance characteristics of silica gel powder are as follows:
Particle form: silica gel powder is usually fine particles, uniform and irregular. The shape and size of the particles may vary, usually appearing as tiny particles or powder.
Color: The color of silica gel powder is usually white or transparent, and a few may appear light gray, yellow or other slight colors, depending on the purity of the silica gel and the production process.
Texture: The texture of silica gel powder is relatively dry, and there are usually gaps between the particles, so it appears light and loose. In terms of touch, it is usually dry and fine, and feels similar to dry sand or powder.
Transparency: High-purity silica gel powder is usually transparent or translucent, and some silica gel powder with different ingredients added may be slightly colored.
Hygroscopicity: silica gel powder has strong hygroscopicity and can absorb moisture in the surrounding environment, especially in low humidity environments, it is more likely to show this characteristic.
Particle size distribution: The particle size of silica gel powder is relatively uniform, usually between a few microns and hundreds of microns, and the specific particle size depends on the purpose and production process.
In summary, silica gel powder usually appears as fine particles, is generally white or transparent in color, has a dry texture, and is hygroscopic and light.
