Detailed Embodiments
[0030] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0031] Referring Figures 1-3 As shown, in the preferred embodiment of the present invention, an artificial environmentally friendly zero-crystallization silica quartz stone forming process includes the following steps:
[0032] S1. Place quartz sand and quartz powder in a melting kettle, and start the first stirring mechanism to completely melt them; then add glass sand and glass powder, and after completely melting, transfer them to a cooling kettle. The cooling kettle uses water and nitrogen to quickly cool the molten liquid to form an amorphous quartz block; then use a grinding kettle to grind the amorphous quartz block into amorphous quartz powder and / or amorphous quartz sand. The mesh number of the amorphous quartz powder and / or amorphous quartz sand is 300-100 mesh; the mesh number of the amorphous quartz sand is: 40-70 mesh, 70-120 mesh.
[0033] Since molten SiO2 is prone to crystallization between 800–1200°C, the fastest cooling needs to be achieved within this temperature range (such as by water quenching or liquid nitrogen). Through liquid nitrogen atomization (-196°C), the cooling rate > 2000°C / s, amorphous ultrafine powder can be obtained. At the same time, there may be internal stress in the material after quenching, and it needs to be heat-preserved and slowly cooled near the glass transition temperature (Tg) (such as about 1200°C for quartz glass) to eliminate stress but avoid secondary crystallization. Therefore, in this application, water and nitrogen are used in combination for rapid cooling. That is, first, liquid nitrogen atomization is used at the beginning, and atomized liquid nitrogen is sprayed while adding the molten liquid for about 10 minutes of cooling, and the anti-crystallization mechanism and the first transmission mechanism in the cooling kettle are started to quickly cool the molten liquid to avoid the formation of crystalline silica. Then, spray water is used to cool the molten liquid. When the water is sprayed for 20 minutes, stop for 10 minutes; then spray water until the cooling is completed.
[0034] S2. Let the ground amorphous quartz powder and / or amorphous quartz sand automatically fall by gravity into a mixing kettle containing unsaturated resin, curing agent, dispersant, coupling agent, and water, and stir and mix the raw materials through the second stirring mechanism to obtain a mixture; wherein the raw materials are composed of the following weight percentages: 10-20 parts of amorphous quartz powder, 15-50 parts of amorphous quartz sand, 10-30 parts of unsaturated resin, 6-15 parts of curing agent, 3-10 parts of dispersant, and 2-7 parts of coupling agent;
[0035] S3. Transfer the mixture through the second transmission mechanism to a pressing and forming device containing a template for pressing and forming to obtain an artificial environmentally friendly zero-crystallization silica quartz stone.
[0036] This step further includes placing the pressed sheet in a furnace at 80-120 °C for curing for 2-3 hours. After curing, the sheet is demolded using a demolding device and stacked for cooling to obtain a finished artificial environmentally friendly zero-crystalline silica quartz stone, thereby effectively reducing the risk of silicosis for workers caused by inhaling silica dust during the subsequent processing of the quartz stone sheet.

The grinding kettle 3 can be provided with two hollow cavities for storing heat, one for placing a heating plate and the other for receiving the heat generated by the cooling kettle.
