Quartz stone, from the production process, said there are two
kinds, one is a die casting, one is cast plate. Die casting plate, as the name
suggests, is a series of procedures, such as high pressure, high shock, high
temperature, etc., because the production process, its hardness and the
proportion is relatively high. Anti seepage, anti cracking, heat resistance,
scratch resistance are very good. The production process of the casting board
is from the original artificial stone production process improvement, the raw
material through the mixing directly into the mold and vacuum forming. The
density and hardness of the high pressure, high pressure and high shock without
high temperature and high pressure are relatively low. Anti seepage, anti
cracking, heat resistance, scratch resistance is relatively poor. Consumers
want to distinguish between casting and die casting plate, you can start from
the following aspects:
1, hardness, casting board hardness is lower than 4, while the hardness of the die casting is equal to or higher than 6, Rongda quartz stone hardness higher than 6.
2, proportion (also known as the relative density, the density of the material and in the standard atmospheric pressure, 3.98 degrees pure H2O (999.972 kg / m3) density ratio), casting in the proportion of less than 2, stone casting in the proportion of more than 2.4, in full compliance with the quartz die casting industry standards.
3, the environmental performance, the casting board is a natural curing, without any treatment, the chemical composition of the material on the human body pose a hazard. The die casting plate is OT curing and high temperature urging curing, to stay in the material inside the chemical composition of all the high temperature treatment, is absolutely environmentally friendly. Therefore, Rongda die casting plate has been to environmental protection and the consumer's trust.
4, the appearance of the casting plate of the larger particles, and the distribution of particles is not uniform, the back is very obvious than the positive. The particles of the die casting plate are uniform and the distribution is uniform.
