DETAILED DESCRIPTION

[0020] The technical solutions in the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 3 As shown, the preferred embodiment of the present invention, the process for forming an artificial environmentally friendly zero-crystalline silicon quartz stone, comprises the following steps: S1. Place quartz sand and quartz powder in a melting kettle, and start a first stirring mechanism to completely melt them; then add glass sand and glass powder, and transfer them to a cooling kettle after they are completely melted.

[0022] Since molten SiO2 is easy to crystallize between 800–1200 °C, it is necessary to achieve the fastest cooling in this temperature range (such as through water quenching or liquid nitrogen). Through liquid nitrogen atomization (-196 °C), the cooling rate is >2000 °C / s, and amorphous ultrafine powder can be obtained. At the same time, the material may have internal stress after quenching, and it is necessary to keep warm and slowly cool near the glass transition temperature (Tg) (such as about 1200 °C for quartz glass) to eliminate stress but avoid secondary crystallization. Therefore, this application uses water and nitrogen to perform rapid cooling, that is, liquid nitrogen atomization is first used at the beginning, while adding the molten liquid, spraying atomized liquid nitrogen for cooling for about 10 minutes, and starting the anti-crystallization mechanism and the first transmission mechanism in the cooling kettle to quickly cool the molten liquid to avoid the formation of crystalline silicon dioxide, and then start spraying water to cool the molten liquid. When the water sprays for 20 minutes, stop for 10 minutes; then spray with water until the cooling is completed.

[0024] This step also includes placing the pressed plate in a furnace at 80-120°C for curing for 2-3 hours, demolding the cured plate using a demolding device, and stacking and cooling to obtain a finished product of artificial environmentally friendly zero-crystalline silicon quartz stone, thereby effectively reducing the risk of silicosis caused by workers inhaling silica dust during the subsequent processing of the quartz stone plate.
