Quartz stone is a kind of artificial stone. It has the characteristics of natural environmental protection, non-toxic, and non-radiation. Quartz stone is popular because of its high hardness, no cracks, sturdiness, and durability, elegant and fashionable colors, and meets the psychological needs of modern urbanites for high-cost performance. Welcome and favor of modern decoration. The most familiar is the use of cabinet countertops. Many people have their own methods to distinguish between true and false quartz stones. And how to accept the installed countertop? Today, the editor will introduce the acceptance criteria for quartz stone countertops.
①The impurity is visually inspected with a straight face of 50 cm. 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 to be 3-5 per square meter.
②The bubbles on the countertop are also visually measured with a 50cm straight face, and no bubbles are allowed on the front of the countertop. ③The cracks are still visually inspected with a 50cm straight face, and there are no cracks, no 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 color differences, and the color deviation from the model plate should not be too large.
⑤Visual inspection of scratches, the tabletop is chamfered and the surface is smooth, without scratches.
⑥ Visual 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 traces.
⑦ Use a level ruler for the size, and the table must be flat, without wavy, and the size error of the appearance is less than ±3mm.
⑧ Visual inspection of the appearance, the tabletop glass is basically the same, the appearance is neat and clean, and there is no stain. For the finish, use a finish meter of 55±5 degrees.
⑨ Visual 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 a pad (due to the material characteristics of the quartz stone product, there are no obvious connection traces at the connection point)
⑩Visual inspection of the basin hole, the basin, and the countertop are combined smoothly, the front and back rubber materials are 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, and the four corners of the furnace hole must be bonded to strengthen the support.
The above standards are compiled and distributed by the editor, not industry standards, nor can they restrict quartz stone manufacturers. But it can be used as an inspection standard for the installation and acceptance of cabinet countertops for your reference.
