In fact, quartz stone is a harmless environmental protection material after processing, but many unscrupulous merchants make money by producing inferior quartz stone. Inferior quartz stone is harmful to human health. The hazards of quartz mainly include the following points:
1. Hazards of inferior quartzite: It is easy to produce powder without abrasion resistance, causing respiratory diseases.
When processing quartz stone, some unscrupulous merchants use inferior plates with too many bubbles, weak impermeability and insufficient hardness to produce quartz stone, which is easy to be broken, wear-resistant and easy to fall off. Long-term use by consumers may cause respiratory diseases by inhaling too much powder.
2. Harm of inferior quartz stone: Long-term volatilization of residual formaldehyde may cause cancer.
In order to reduce costs, some unscrupulous merchants add glue containing formaldehyde as a solvent.
After being processed into a countertop, excessive formaldehyde will still remain, and strong formaldehyde odor will be continuously volatilized within 3-5 years. Indoor air circulation or high temperature will accelerate the volatilization of such toxic substances, and long-term contact is very likely to cause cancer.
3. Harm of inferior quartzite: Organic solvents and heavy metals harm the digestive system.
Some unscrupulous merchants use inferior inorganic pigments containing heavy metals such as lead or cadmium in the production process, and directly add organic solvents. After these inferior quartz stone plates enter the family, they will directly enter the digestive system with food as the carrier through harmful substances such as heavy metals, which is harmful to human health.
How to identify quartz stone?
Quartz stone is the best choice for cabinets and countertops in home improvement. There are many inferior quartz stone countertops in the market, and consumers don't know much about quartz stone. How to identify the quality of quartz stone when purchasing quartz stone countertops?
1. Look, the color of the visual sample is pure and not turbid, the surface has no similar plastic texture, and there are no pores on the reverse side of the plate.
2. Touching, touching the surface of the sample has a silky feeling, no astringency, and no obvious concave-convex feeling.
3. Scraping: Scrape the surface of the plate with nails without obvious scratches.
4. Check whether the product has ISO quality system certification, quality inspection report, product warranty card and related anti-counterfeiting marks.
5. Smell, the nose can't smell the pungent chemical smell.
6. Touch, the same two samples collide with each other, which is not easy to break. The so-called harm of quartz stone is actually caused by unqualified production methods of unscrupulous merchants. Therefore, consumers must carefully identify the authenticity of quartz stone when purchasing, and don't let black-hearted businesses benefit and harm their health and interests.
