Quartz stone is a kind of artificial stone. It has the characteristics of natural environmental protection, non-toxic and non-radiative. Quartz stone is high-hardness, crack-free, durable and elegant. It meets the psychological needs of modern urban people who advocate high cost performance. The welcome and favor of modern decoration.
The most familiar is the use of the countertops.
Many people have their own methods for distinguishing between true and false quartz stones.
And how to accept the installation of the finished countertop?
Today, we will introduce the acceptance criteria for quartz stone countertops for ordinary players (non-professionals).
1 Impurities are visually measured on a 50cm straight surface. No more than 3 impurities per square meter are allowed. Each diameter is <0.5mm and there is no concentrated distribution. The same number of raw material variegated particles are allowed to be 3-5 per square meter.
The bubbles on the 2 mesa are also visually observed on a 50cm straight surface, and no bubbles are allowed on the front of the countertop.
3 The crack is still visually observed with a 50cm straight surface, and the surface of the mesa has no cracks, no cracks and obvious crack repair marks.
4 color visual inspection, the plate used in the same set of countertops is not allowed to have color difference, and the color deviation of the sample plate should not be too large.
5 scratches visual inspection, table chamfering and smooth surface, no scratch marks.
6-line visual inspection, each set of countertops is clear and smooth, the waterproof line has no collapse, no obvious unevenness and visible processing marks.
7 size using level, the table surface is required to be flat, no wave shape, the size error is less than ± 3mm.
8 Appearance visual inspection, the surface gloss is basically the same, the appearance is neat and clean, no stains. The finish is 55 ± 5 degrees using a finish meter.
9 The connection is visually observed. The platform connection line is straight, smooth and smooth, without glue watermark. At the bottom of the connection port, there is reinforcement of the pad (due to the material characteristics of the quartz stone product, there is no obvious connection mark at the connection).
10 potholes visual inspection, the basin and the countertop are combined and flat, the positive and negative rubber compound is full and firm, and the combined line is straight and beautiful. The hole of the furnace hole is straight, there is no obvious processing mark, the surrounding arc is natural, and the four corners of the furnace hole must be bonded to the reinforcement.
The above standards are not professional standards of the industry, nor can they restrict the quartz stone manufacturers. Sometimes the owners who know less about the quartz stone industry will be confused. This standard can be used as a general test standard for the installation and acceptance of countertops.
