Hazards of Quartz Stone

1, not wear-resistant, easy to produce powder, causing respiratory diseases.

Some unscrupulous merchants in the market choose inferior plates with too many bubbles, weak penetration resistance and poor hardness for production, which are easy to break, wear-resistant and easy to fall off. Customers may cause respiratory diseases by inhaling too much powder for a long time.

2. Long-term volatilization of residual formaldehyde may lead to 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 the strong formaldehyde smell will evaporate continuously within 3-5 years. Indoor air circulation or high temperature will accelerate the evaporation of such toxic substances, and long-term contact is very likely to cause cancer.

3. Organic solvents and heavy metals are harmful to 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.

Quartz stone characteristics

1, scrape.

The timely content of quartz stone is as high as 94%. Seasonal crystal is a natural mineral whose hardness is second only to that of diamond, and its surface hardness can be as high as Mohs hardness of 7.5, which is much larger than sharp tools such as knives and shovels used in the kitchen and will not be scratched by it.

2, not old

The shiny surface of quartz stone has undergone more than 30 complicated polishing processes, and it will not be scratched by knives and shovels, infiltrated by liquid substances, and will not be yellowed and discolored. Daily cleaning can be done simply by rinsing with clean water, which is simple and easy. Even if it is used for a long time, its surface is as bright as the newly installed countertop and needs no maintenance.

3. It won't burn

Natural aging crystal is a typical refractory, and its melting point is as high as 1300 degrees. Quartz stone made of 94% natural and timely is completely flame retardant, will not burn due to contact with high temperature, and has incomparable high temperature resistance characteristics such as artificial stone.

Hazards of Quartz Stone

Quartz stone, chemical name: silica, can be divided into four types according to its use: piezoelectric response, optical response, smelting response and grinding response. As a timely smelting export, it is used in metallurgical building materials and chemical industry.

There are few quartzites exported from Shanghai Port. In 1950s, the Shanghai Commodity Inspection Bureau accepted the entrusted inspection, and in 1970s, the export volume gradually increased. 1978 quartzite is listed in the category list, but the export quantity of Shanghai port is still very small. Until 1989, only three batches of quartzite (1 120 tons) were inspected. 1990, totally 5 batches (470 tons) were inspected. The inspection method is in accordance with the China People's Professional Standard ZBD6200 1-85 Chemical Analysis Method for Quartz Stone (Sand) for Import and Export issued by the Ministry of Foreign Trade. The contents of silicon dioxide and impurity iron in the inspection items are the main components. Silicon dioxide is not radioactive and can be used normally. Of course, because the stone floor is cooler, it is not as good as the wooden floor in winter.

What are the hazards of Shi Ying countertops?

Quartz stone is harmless and environmentally friendly after processing, but many unscrupulous merchants make money by producing inferior quartz stone. Inferior quartz stone is harmful to human health.

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 the strong formaldehyde smell will be continuously volatilized within 3-5 years. Indoor air is not ventilated or the temperature is too high, which will accelerate the volatilization of such toxic substances. Long-term exposure 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.

Is quartz stone harmful to people?

Quartz stone is harmless to people. It is a new type of environmental protection and green building interior decoration material, which has no radioactive pollution and can be reused.

Details are as follows:

1, quartz stone

Usually, the quartz stone we are talking about is a new type of stone synthesized by more than 90% timely crystals, resins and other trace elements. It is a large-size plate pressed by a special machine under certain physical and chemical conditions, and its main material is timely.

2. Formation process

In the process of intrusive evolution, due to the change of temperature and pressure, the hydrothermal solution rich in SiO2 _ 2 differentiated, and the bedding and cracks infiltrated into the metamorphic rock series of pre-magmatic rocks, or invaded along the contact fracture zone of pre-magmatic rocks, forming vein-like Shi Ying ore bodies.

3. Timely classification

Quartz stone types: pink, green, Bai Shiying and yellow.

Quartz stone can be divided into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand and silicon micropowder.

4. Main uses

Widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc. ) and home decoration (kitchen countertops, washstands, kitchen walls, dining tables, coffee tables, window sills, door covers, etc.). ), is a kind of environmental protection and green new building interior decoration material without radioactive pollution and reusable. It should be pointed out that the quality of quartz stone is directly related to the content of resin. The higher the timely content in quartz stone, the lower the resin content, the better the quality, the closer it is to nature, and the less prone to deformation.

What are the hazards of inferior quartz stone?

Organic solvents and heavy metals can 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. Quartz stone has become the most ideal cabinet countertop material because of its excellent properties such as high hardness, corrosion resistance, high temperature resistance and difficult bleeding, and is highly respected by people in the industry and consumers. However, looking at the domestic quartz market, it is difficult for consumers to distinguish between good and bad.

Long-term volatilization of residual formaldehyde may cause cancer. Some unscrupulous merchants add glue containing formaldehyde as a solvent to reduce costs. After being processed into a countertop, excessive formaldehyde will still remain, and the strong formaldehyde smell will be continuously volatilized within 3-5 years. Indoor air is not ventilated or the temperature is too high, which will accelerate the volatilization of such toxic substances. Long-term exposure is very likely to cause cancer. In pursuit of profit, inferior quartz stone production enterprises ignore consumers' rights and interests. Although this kind of plate is cheap, it seriously harms the health of consumers.

Therefore, consumers must be cautious when purchasing quartz stone plates, so as to avoid buying "toxic plates" by mistake, introducing long-term toxic sources to their families and endangering their lives and health. High-quality quartz stones are all made of environmentally friendly materials. However, in order to reduce costs, some businesses with backward production equipment and technology choose harmful raw materials, which not only destroys the market integrity, but also has a serious impact on consumers' physical and mental health! Powder that is not wear-resistant is easy to cause respiratory diseases. Some unscrupulous merchants use inferior plates with too many bubbles, weak penetration resistance and insufficient hardness for production, which are easy to break, wear-resistant and easy to drop powder. Consumers inhaling too much powder in long-term use may cause respiratory diseases.

Harm of Quartz Stone Other information: Quartz stone surface is smooth and smooth, without scratches. The dense and non-porous material structure makes bacteria have nowhere to hide and can directly contact food, which is safe and non-toxic! High-quality quartz stone is made of selected natural timely crystalline minerals, and its silicon dioxide content exceeds 99.9%, which is purified in the manufacturing process. Raw materials do not contain any heavy metal impurities that may cause radiation, and 94% timely crystals and other resin additives protect quartz stone from the danger of radiation pollution. The main material of quartz stone is timely, and the rich TINT makes it have the texture of natural stone and beautiful surface luster.

Can be widely used in public buildings and home decoration fields (kitchen countertops, washstands, kitchen and bathroom walls, dining tables, coffee tables, window sills, door covers, etc.). ), is a kind of environmental protection and green new building interior decoration material without radioactive pollution and reusable. It should be pointed out that the quality of quartz stone is directly related to the content of resin.

The higher the timely content in quartz stone, the lower the resin content, the better the quality, the closer it is to nature, and the less prone to deformation. Experts pointed out that when the resin content in quartz stone is greater than 10%, its corresponding technical indicators will be reduced, and quartz stone at this time can no longer be called real quartz stone.

Identification methods of quartzite: First, quartzite with good smell is made of environmentally friendly materials and has a natural smell. Glue containing formaldehyde was added in the production process of inferior quartz stone, and the produced board had a strong smell of formaldehyde. You can't choose this kind of quartz stone no matter how cheap it is, which is harmful to life! Second, the key or pencil has scratches, and the scratches are deep, which is obviously unqualified; Third, 200 mesh sandpaper grinding, easy to drop stone powder is unqualified; Four, the upper and lower edges of the cutting surface, there are cutting cracks as unqualified.

Does quartz stone have radiation? Is it harmful to human body?

Non-toxic and radiation-free, harmless to human body.

Quartz stone surface is smooth and smooth, without scratches. The dense and non-porous material structure makes bacteria have nowhere to hide and can directly contact with food, which is safe and non-toxic.
