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 one is the use of cabinet countertops. Many people have their own methods of distinguishing true and false quartz stones. And how to accept the installed countertop? Today, the editor introduces the acceptance criteria for quartz stone countertops.
①The impurity is visually inspected by 50cm straight face. No more than 3 impurity particles per square meter are allowed. Each particle is less than 0.5mm 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 straight face of 50cm, and no air bubbles are allowed on the front of the countertop.
③The cracks are still visually inspected with 50cm straight face, and there are no cracks, 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 model plate shall not be too large.
⑤Visual inspection of scratches, tabletop chamfering, and surface smooth, no scratch marks.
⑥Line type visual inspection, the line type of each set of countertops is clear and smooth, the waterproof line has no cracks, no obvious unevenness, and visible processing traces.
⑦ Use a level ruler for the size, and the table should be flat, without a wavy shape, and the size error is less than ±3mm.
⑧ Visual inspection of the appearance, the tabletop glass is basically the same, the appearance is neat and clean, no stains. The finish is 55±5 degrees using a finish meter.
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, the connection point has no obvious connection traces)
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 traces, and the surrounding arc transition is natural. The four corners of the furnace hole must be bonded to strengthen the support.
