How to distinguish between real quartz stone and fake quartz stone

Now many families in the kitchen decoration to buy cabinets, often choose to scratch, not old, not burning quartz stone as the main plate, but the quality of quartz stone on the market is uneven, consumers often do not know how to start when choosing. carrara quartz The following Pope Xiaobian will teach you how to identify the true and false quartz stone, to avoid being cheated.

Quartz stone countertop is a new science and technology artificial stone synthesized by small quartz stone, which has a variety of colors and has the texture and luster of Chinese natural building stone. Quartz stone is a kind of non-radioactive environmental pollution, stone benchtop colours reusable environmental protection, green new building interior decoration materials, so widely used in kitchen countertops, dishtops, kitchen and bathroom walls, tables, coffee tables, windowsills, door covers and other fields.

The shiny surface of the quartz stone has undergone more than 30 complex polishing processes. Even if used for a long time, quartz vanity top the surface is as bright as a newly installed countertop. The real quartz stone countertop has the characteristics of high hardness, corrosion resistance and high temperature resistance, even if sharp tools such as knives and shovels are used, they will not scratch the surface. It also has excellent resistance to acid and alkali corrosion in the kitchen, and high temperature resistance that other artificial stones and other countertops cannot match.

In quartz stone, the higher the quartz content, the lower the resin content, the better the quality, and the closer to natural deformation, the more difficult it is. When the resin content of quartz stone exceeds 10%, it cannot be called true quartz stone. In a variety of products, how to identify the quality of the quartz stone table, the purchase of real quartz stone products, is particularly important. How to distinguish between true and false quartz stone, become a procurement master, can be tested according to the characteristics of quartz stone.

Method 1: Immersion test with hydrochloric acid

In order to maximize profits, some manufacturers will adulterate calcium carbonate in the raw materials of quartz stone countertops. However, calcium carbonate reacts with acids. If you choose this type of countertop, it is easy to change in later use. So you can ask for samples when buying, soaked in dilute hydrochloric acid or other acidic liquids. If the product contains calcium carbonate, it will react with the acid.

With a spoonful of white vinegar is poured on the artificial stone and quartz stone surface, 30 seconds later, if many tiny bubbles are generated, it is fake quartz stone. Because the calcium carbonate in the false quartz stone will chemically react with white vinegar to produce bubbles. This kind of countertop has low price, easy aging, cracking, color absorption and short service life.

Method 2: Test for seepage

High-quality quartz plates have the same dense and uniform surface and internal structure, resulting in low water absorption and high permeability, while imitation quartz stone production equipment and technology are often limited to similar appearance, but the internal structure is loose and porous, weak impermeability, water absorption and permeability. When you choose to buy, you can pour the soy sauce on the quartz stone countertop to check whether it will be stained, the color of the poor quality quartz stone countertop of the day, the quality will not.

Method 3: Check wear resistance with a knife.

Quartz countertops are made of silica, which has the highest hardness. The quartz stone on the market is made of quartz crystals and resins and is generally labeled with a quartz content of about 93%. Therefore, the possibility of breakage is small and relatively wear-resistant. False quartz resin content is high, the surface hardness will be low, it is easy to scratch. When buying, you can wait at the table and try to make a stroke with the knife. Poor quality quartz stone with a knife after scraping, there will be powder. High-quality quartz stone has high hardness, there will be no powder after scraping, and there will be the color of the metal knife left on the quartz stone.

Method 4: Check heat resistance with fire

Because of the characteristics of its own material, quartz stone determines its high temperature resistance, the temperature below 300 degrees Celsius will not have any impact on it, that is, it will not deformation and fracture. Poor quality quartz resin content is too high, the heat resistance will also have an impact on the reduction. Therefore, we can take advantage of this by burning the sample with a lighter and so on, and then see if we can leave traces on it. Add some dishwashing liquid and water and then scrub, high-quality quartz stone can be basically wiped clean after burning.

How to identify the advantages and disadvantages of quartz stone

1. Hardness: Surface Mohs hardness is 7. The simple test method is to observe the state of the failure point by pressing the sharp object, and there will be no scratches.

2. high temperature resistance: can withstand 300℃. Stainless steel cups filled with boiling water on the table for 30 minutes will not change color. Or use burning cigarette butts on quartz stone, will not change color.

3. Recognize the logo on the front of the quartz stone.

4. Environmental protection: It can provide green environmental protection certification tested by authoritative departments.

5. Fire resistance: The use of 10mm × 30mm quartz strip can not burn on an open flame.

6. Acid and alkali resistance: The surface is corroded by 3% hydrochloric acid solution or 100gu002FL citric acid solution and 30gu002FL sodium hydroxide or potassium hydroxide solution, and the surface has no significant change.

7. Water absorption: less than 0.04%, sprinkle a small amount of water on the surface of quartz stone for 24 hours to observe the color without whitening phenomenon.

8. High-quality quartz stone does not contain residual solvents, no irritating chemical odor.
