Welcome and favor of modern decoration. The most familiar one is the use of cabinet countertops. Many people have their own methods to distinguish true and false quartz stones. And how to accept the installed countertop? Today, the editor introduces the acceptance criteria for quartz stone countertops, such as statuary marble white quartz countertops.
①The impurity is visually inspected with a straight face of 50 mm. Impurities per square meter are not allowed to exceed 3, and each particle is less than 0.5 mm in diameter and has no concentrated distribution. The raw material variegated particles of the same mesh number are allowed 3-5 per square meter. ②The air bubbles on the countertop are also visually measured with a 50cm straight face, and no air bubbles are allowed on the front of the countertop. ③The cracks are still visually inspected by 50cm straight face, and there is no crack, broken, and obvious crack repair marks on the surface of the table. ④ Visual inspection of the color, the plates used in the same set of countertops are not allowed to have a color difference, and the color deviation from the sample plate should not be too large. ⑤Visual inspection of scratches, tabletop chamfering, and surface smooth, no scratch marks. ⑥Visual inspection of the line type, the line type of each set of countertops is clear and smooth, and the waterproof line has no cracks, no obvious unevenness, and visible processing marks. ⑦ Use a level ruler for the size, and the table should be flat, without wavy, and the size error of the appearance is less than ±3mm. ⑧Visual inspection of the appearance, the tabletop glass is basically the same, the appearance is neat and clean, and there is no stain. The finish is 55±5 degrees using a finish meter. ⑨Visual inspection of the connection point, the connection line of the tabletop is straight, polished and smooth, without glue watermark, and the bottom of the connection port is reinforced with pads (due to the material characteristics of the quartz stone product, there are no obvious connection traces at the connection point) ⑩Bath hole Visual inspection shows that the combination of basin and countertop is smooth, the positive and negative rubber material is full and firm, and the joint line is straight and beautiful. The wall of the furnace hole is straight, without obvious processing marks, and the surrounding arc transition is natural.
