Now, we do a contrast experiment between glass-ceramics and natural stone. We pour ink on marble and glass-ceramic glass, wait a moment, the ink on the glass-ceramics can be easily wiped off, and the ink on the marble remains. Why is this? Natural stone such as marble and granite has a rough surface and can filth. Glass-ceramics do not have this problem. As we all know, the main component of marble is calcium carbonate. Building it into a building can easily react with the water and carbon dioxide in the air. This is the reason why marble buildings are discolored for a long time, and crystallized glass is almost impossible to match. The air reacts so it can last a long time.
ExpertsShao said that there are two major breakthroughs in this invention, namely the ratio of raw materials and the design of the process. Among them, the design of the process is the key to the technology. To prepare the glass-ceramics, the raw materials must be proportioned first, put in the furnace, and melted. After all of the melt, the melt is poured onto an icy iron plate. This is called quenching. After quenching, the raw materials have become a piece of material. Crystal glass, this step is the sintering process. Now, we mash up the glass, put it into a mold, smooth it, and put it into the furnace again. This calcination makes its atomic arrangement regular, a process from ordinary glass to glass-ceramic.
Most of the waste residue contains most of the components that make glass-ceramics. We use computer tests to determine the chemical composition of existing materials, add missing parts, and greatly reduce costs. Glass-ceramics use waste residue and waste soil as raw materials, which is conducive to environmental governance, can be turned into waste, and is synchronized with environmental protection work in various regions.
