Q:Why does vermiculite have gold or silver on its surface?
Vermiculite can be according to the stages can be divided into vermiculite and expanded vermiculite, according to color classification can be divided into golden vermiculite, vermiculite, vermiculite milky white silver white.The selective absorption of minerals by visible light is the main reason for the color of objects. Different colors of light waves are typically represented in different wavelengths, in nanometers, 1nm=109m. The visible light wavelength between 390 - 760nm, the wavelength from long to short in order to show the red orange yellow green blue purple color. Their blend color is white.Minerals are varied in color. One of the reasons for color rendering is that the white light passes through minerals during the process of internal electron transition, resulting in selective absorption of different light colors. The other is caused by physical optical processes. The main cause of the internal electron transition in minerals is the existence of pigment ions, such as Fe3+, which makes hematite red and V3+ makes vanadium garnet green. It is the lattice defects that form "color centers", such as the purple of fluorite. In mineralogy, colors are generally divided into 3 categories: self color is the intrinsic color of minerals; color is the color caused by mixing; false colors are due to some physical optical process. Such as bornite fresh face is red copper oxide film due to surface oxidation, caused by the interference of light and blue purple tarnish. The inner mineral containing directional fine inclusions, when the mineral can occur when the color change colors, transparent minerals or cleavage fracture can sometimes cause the interference of light and appear like iridescent rainbow.

Vermiculite is a kind of thermal insulation material, even if you do not do roofing waterproof, that after finishing the vermiculite ramming, also must use the cement mortar to make the 2~3CM protection layer. Finished cement mortar protection layer after drying, and then laying asphalt or SBS waterproof coiled material and other waterproof material. Need to say is that asphalt is a waterproof material, cement is a protective layer of thermal insulation material, but also waterproof material of the adhesion layer, and vermiculite is thermal insulation material! Can not be said to be good asphalt, vermiculite, or cement, vermiculite, good drops are a kind of Dongdong Oh!
