How to do quartz stone mesa quality identification? Isn't thickness the only criterion

The countertop is an important part of the cabinet, and the material is also diverse, but quartz stone is the most commonly used. quartz slab This is because the quartz stone plate is rich in color, natural texture, environmental protection, and is a high-quality substitute for natural stone in current architectural decoration. So how to identify the quality of quartz stone countertops? Thickness is not the only criterion.

Many people in the purchase of quartz stone countertops, often the thickness can be used as a quality management standard, engineered stone benchtops but we also need to take into account other influencing factors, can not be themselves as a sole standard. Next, let's talk about quartz stone mesa quality identification how to do.

Thickness is not the only criterion

There are many varieties of quartz stone sales market, but most of the thickness is 15 mm, but the thickness is also 20 mm and 30 mm. engineered stone supplier It may be a common misconception that the thicker the better, it will be more durable. In fact, the thickness is not the only criterion to judge its quality, because its thickness will change according to the scope of use and change.

We often hear that quartz stone is made up of 90% quartz sand and 7% resin. What's the other 3%? In fact, it is titanium dioxide, color powder, curing agent, accelerator. If the quality of raw materials is all up to standard, coupled with a scientific ratio and strict production process, product quality can be guaranteed. Uncoordinated proportions and inferior raw materials will lead to a decline in the quality of finished products. The impact of production equipment on quality is also important. Before pressing, the vacuum value should be above -99 to avoid bubbles in the plate. The pressing pressure can not be less than 50 tons, so that the density of the sheet can reach the required value of 2.6g/ u002Fm3, and the water absorption of the finished sheet can not exceed 0.02%.

Therefore, the thickness of quartz stone is not a standard for judging quality. Due to the different application range, there may be certain requirements for thickness.

For example, the cabinet table, can be divided into pad type and pad type, 15mm pad type is best, pad type needs to glue reinforcement on the ground (backplane). The floors are mostly 20mm or 30mm panels, and the walls are mostly thin. In fact, there is no good or bad, only suitable and unsuitable. The scope of application is not the same, so the requirements for products are not the same.

Quartz stone countertop work quality identification how to do

Judgment method one: Painting

The surface finish of quartz stone represents the resistance to pollution, and it is very important to judge the surface finish of quartz stone. The simplest way is to use the mark on the quartz stone to draw, see if you can erase, can erase the strong anti-fouling, erase the poor anti-fouling, not recommended to buy. In addition, regular manufacturers have jet coding on the back of quartz stone, pay attention to the logo.

Judgment method two: row

Hardness is also the identification of wear resistance. The easy way is to use a steel knife, but the key is not useful for identification. Quartz stone is made of 94% of the time and 6% of resin, and the hardness reaches 7 degrees, while granite is made of marble powder and resin, so the hardness is generally 4-6 degrees. Simply put, quartz stone is harder, more scratch resistant, and more wear-resistant than granite.

Steel knife across, leaving a white mark is false quartz stone, because the hardness of the plate is not as good as the steel knife, the steel knife cuts the surface, exposing the white inside. The pure quartz stone by the steel knife across, will only leave a black mark, is the steel knife cut out of the quartz stone, but left the traces of the steel knife, a black and white, true and false difficult to distinguish.

Judgment method three: burn

Quartz stone, because of its own material characteristics, determines its high temperature resistance, the temperature below 300 degrees Celsius will not have any effect on it, that is, it will not be deformed and broken. The stone contains a lot of resin, so it is particularly easy to deform and carbonize at high temperatures. Press the lit cigarette butt on the table or light it directly with a lighter. No marks are the real thing, scorch marks are the fake.

Judgment method four: acid

High-quality quartz stone countertop design will generally add 100% high-quality aluminum powder, a small spoon of edible white vinegar can make all our inferior artificial stone, quartz stone show the original shape. However, it is not effective for other product types of vinegar, such as old vinegar.

Pour 1 tablespoon of white vinegar over the artificial stone countertop and quartz stone countertop. After 30 seconds, if it produces a lot of little bubbles, it's fake quartz. Because the calcium carbonate in artificial quartz reacts with white vinegar to create bubbles. This countertop has low price, easy aging, cracking, color absorption and short service life.
