Matter artificial stone, foam glass, devitrified glass, glassware, artificial color sand, glass microballoon, colored bulb, glass ceramics system
Product, high temperature binder etc..
Nature of glass artificial stone is a field relatively good using post-consumer glass, needs not move through other glass and recycles
The high-temperature fusion of method etc. only needs room temperature to be broken into glass sand use, energy-saving to have outstanding advantage than other methods, and makes
At nature of glass artificial stone be integrated with artificial quartz stone and have many advantages, such as high intensity, high rigidity, wear-resisting, other glossiness, thoroughly
Luminosity and anti-pollution are more more excellent than artificial quartz stone performance, overcome the exploitation meeting of the raw material high grade quartz sand of artificial quartz stone
Destroy natural resources and ecological environment disadvantage.Therefore, the green of the substitution quartz sand production of resourceful recycling glass is utilized
