The dazzling array of brands makes people feel dazzled, and the minded business is even more amazing, especially the quality of artificial stone. How to identify the quality of artificial stone?

    A look: the visual color of the product is pure, the surface has no similar plastic texture, and the front of the plate has no air holes.

    Second smell: Nasal smells no pungent chemical smell.

    Three touches: The surface of the hand touched the sample has a silky feel, no flaws, and no obvious unevenness.

    Four strokes: Use the nails to scratch the surface of the board without visible scratches. Quartz stone is drawn with a sharp sharp weapon.

    Five touches: The same two samples are knocked against each other and are not easily broken.

    Six grinding: grinding with sandpaper, a large amount of powder layer falling off belongs to calcium powder quartz stone

    Seven falls: look at its hardness and strength, take a piece of material, you can have a size of 200 * 200mm, and force it to fall on the concrete floor. The artificial stone with poor quality will fall into many small pieces of pulverization; In two or three pieces, and if you don't have enough force, you can bounce off the ground.

    Eight burns: Take a slender strip of artificial stone and put it on the fire. The artificial stone with poor quality is easy to burn, and the burning is very prosperous. The artificial stone of Yuxi can't be burned unless it is added with combustion-supporting things. Automatically extinguished.

    Nine check: Check whether the product has quality system certification, quality inspection report, anti-counterfeiting mark, etc.

    Method for identifying pure aluminum powder board and calcium powder board

    1,Eye observation

    Observing with the careful eye, the most direct is to see whether there is a pure aluminum powder anti-counterfeit mark on the cabinet plate. Secondly, the aluminum powder plate has a high degree of transparency, and the plate has a distinct layering. The deeper particles of the plate (if any) will also appear; The color of the calcium powder board is dim, the permeability is poor, the surface of the board is not layered, and only the surface particles are visible.

    2. Chemical methods

    A 30% nitric acid solution was dropped on the surface of the plate, and the aluminum powder plate hardly foamed, and the calcium powder plate and the nitric acid solution immediately dropped a large amount of bubbles. This method has been recommended and used by the Artificial Stone Special Committee of the Furniture Industry Association (the “pure aluminum powder detector” currently used on the market).

    3. Combustion method

    Take a small square piece of about 50 square centimeters, put a corner of the sample block against the blue flame of the alcohol lamp, make it ignite, and then slowly leave the flame, the aluminum powder plate flame will automatically extinguish within 3 seconds; and the calcium powder The flame of the board will last for more than 10 seconds.

    4. Fragmentation method

    The material of the board is about 30 cm long. The sheet is cut with a circular head knife for processing the countertop. The aluminum powder board is easy to cut, the flying dust is relatively small, and the knife hair is hot and small; while the calcium powder board is more laborious to cut, dust Larger, the knife hair is hot.
