To distinguish between true and false China quartz stone

China quartz stone is 90% quartz sand powder and 10% resin in the vacuum under high pressure forming, high temperature state of the new shape of stone. Is a non-radioactive pollution, reusable environmental protection, green new building materials and decorative materials. Its main body is quartz sand powder, about 90%, resin, paint and other auxiliary materials accounted for about 10%.

China quartz stone countertops Price: 180 yuan a meter or more than 200 meters must be a man-made stone, artificial stone looks like China quartz stone, but the hardness and oil leakage is very poor, and not environmentally friendly.China quartz stone must be fully meet the following four conditions, even if a condition does not meet the pseudo-China quartz stone.

The hardness of China quartz stone must be provided by quartz sand. Glass is not quartz, the proportion of glass particles in China quartz stone plate (mass percentage) must be below 20%.

Resin: Resin is made of China quartz stone matrix material, in the China quartz stone plate from the role of bonding and to provide the role of China quartz stone sheet toughness. China quartz stone used in the resin there are two: one is unsaturated polyester resin, the other is acrylic resin (acrylic resin). But the domestic manufacturers are using 100% unsaturated polyester resin, acrylic China quartz stone has not been reported in the country.

Filling material: China quartz stone filler main component of silica, which are: China quartz stone sand, China quartz stone powder, foundry sand, broken glass, shells, sea sand. The main role is: First, fill the volume; Second, to enhance the stone texture of China quartz stone; Third, to enhance the mechanical properties of China quartz stone; Fourth, as a flame retardant.

Pigment: The role of the pigment in the China quartz stone is the deployment of color varieties, so that the color is colorful, in theory, any color can be deployed through various types of pigments.

Curing agent: curing agent is essential for the production of China quartz stone additives, good China quartz stone are used high temperature curing molding.

Other additives: resin is a polymer material, the appropriate addition of some additives can improve its process performance, improve production efficiency, improve the performance of China quartz stone, extended life.

The following is to determine the cabinet China quartz stone counterfeit and false four methods, really very simple, quickly collection up!

Judgment Method 1: Look

It is important to judge the merits and demerits of China quartz stone because the finish represents stain resistance. The easiest way is to use a marker on the China quartz stone to see if it can be wiped, can be wiped off to explain the strong stain resistance, can not afford to explain the poor stain resistance, it is recommended not to buy.

In addition, the regular manufacturers of China quartz stone in the back have a code, pay attention to see signs.

Judgment method two: plan

Hardness is the identification of wear resistance, the simple method is to use steel knife plan, with the key can not achieve the role of identification. China quartz stone is made of 94% quartz and 6% resin, hardness of 7 degrees, and the stone is made of marble powder and resin synthesis, so the hardness is generally 4-6 degrees, simply said that the China quartz stone ratio Hard stone, more scratch-resistant, wear-resistant.

Steel knife across, leaving the white printed fake China quartz stone, because the hardness of the plate as steel, was cut off the surface of steel knife, revealing the inside of the white. The pure China quartz stone was crossed by steel knife, will only leave a black print, steel knife is not moving China quartz stone, but left the traces of steel caused by a black and white, true and false legislation.

Judgment Method 3: burn

China quartz stone because of its own characteristics of the material, determines its high temperature characteristics, 300 degrees Celsius below the temperature will not have any impact on it, that is, will not occur deformation and fracture; Gang stone because it contains a lot of resin, so in the High temperature conditions are particularly prone to deformation and performance of the phenomenon of charred.

Will be lit cigarette butts on the table, or directly burned with a lighter, no trace of the real goods, there are coke traces of fake.

Judgment Method 4: Acid

High-quality China quartz stone countertops will generally add 100% premium aluminum powder, a teaspoon of edible white vinegar can make all the inferior artifact stone, China quartz stone show prototype. But other types of vinegar invalid, such as vinegar invalid.

With a spoonful of white vinegar poured on the artificial stone and China quartz stone on the table, 30 seconds later, if there are many tiny bubbles that is false China quartz stone. Because the pseudo-quartzite in the calcium carbonate and white vinegar will be a chemical reaction, resulting in bubbles. Such countertops are low prices, easy to aging, cracking, picking color, short service life.
