What harm does inferior quartz stone have?
Organic solvents and heavy metals endanger the digestive system. Some unscrupulous merchants use the inferior inorganic pigments such as lead or cadmium in the process of production and directly add organic solvents. These poor quality quartz stone board after entering the family, through heavy metals and other harmful substances, food as the carrier, directly into the digestive system, endangering human health. Quartz stone with high hardness, corrosion resistance, high temperature resistance, easy bleeding and excellent performance, become the most ideal materials for the cabinet table, preparing a highly praised by the industry and consumers, but the quartz stone jumbly a market, the price difference is big, so that consumers found quality.
High quality quartz by the natural quartz crystal minerals, the SiO2 content is more than 99.9%, and in the manufacturing process to purify, any radiation may lead to heavy metal impurities containing raw materials, 94% quartz crystal and other resin additive made of quartz stone there is no risk of contamination. Quartz stone is the main material of quartz, color rich combination, so that it has natural stone texture and beautiful surface gloss. Can be widely used in public buildings and home decoration (kitchen countertops, commode, kitchen wall, dining table, coffee table, window, door, etc.) is a kind of non radioactive pollution, reusable environmental protection, green building new indoor decoration materials. It should be pointed out that the quality of the stone is directly related to the content of the resin. The higher the content of quartz in quartz, the lower the amount of resin, the better the quality. The closer to the natural, the less difficult to deformation. Experts pointed out that when the content of resin in quartz stone is greater than 10%, the corresponding technical indicators will decline, and at this time the quartz stone can not be called the real stone.
The residual formaldehyde volatilization may lead to cancer long-term part of unscrupulous businesses in order to reduce the cost of adding formaldehyde glue solvent, processing will remain over the table of formaldehyde, formaldehyde flavor 3-5 years of uninterrupted evaporation strong, indoor air circulation and high temperature, accelerate such toxic substances volatile, long-term exposure. Most likely carcinogenic. Poor quality quartz stone producers for the pursuit of profit and ignore the interests of consumers, this kind of plate although the price is low, but seriously endanger the health of consumers. Therefore, consumers in the purchase of quartz stone plate must be cautious, so as to avoid the purchase of "poison" into long-term source for the family, family life and health hazards. High quality quartz using environmental protection material production, but some backward production equipment and technology businesses in order to reduce the cost, use of hazardous materials, not only undermine the integrity of the market, it has a serious impact on the health of consumers! No wear, easy to produce powder, cause respiratory diseaseSome unscrupulous businessmen use containing excess air bubbles, the anti penetration force is weak, insufficient hardness inferior plate production, easy to break, do not wear, easy to fall powder, consumers in the long-term use, may be due to excessive inhalation of powder caused by respiratory diseases.
