Quartz stone consumption guide

First, the common quality problems of quartz stone

Color difference

Quartz stone resin content is low, more than 90% is quartz, quartz is a natural mine, that is, more than 90% of its ingredients are from natural. The quartz color of most mines is white, but there are also differences, some are yellowish, some are blue, sometimes the same mine has a slight difference in the color of the quartz from the hill and the tail. According to this situation, quartz stone plates generally have a slight color difference. After the factory inspection, the color of the same product batch is basically the same (although it is lower than the standard of ordinary artificial stone, it is difficult to seamlessly splicing) , the plates of different product batch numbers will have slight color difference. The same batch of plates must be connected during processing, and different batches of plates are not allowed to be connected. If there is a large color difference after the same batch of plates is connected (a slight color difference is normal), please confirm on the spot whether the grinding degree of the plate is consistent, and the degree of sanding of the dark plate will directly affect the color difference. Next, wipe it with a damp rag and confirm it under natural light. It is best to observe it at the same angle.

Impurity

Because more than 90% of the quartz stone plate components are from natural, quartz ore will have yellow skin, so the quality control of quartz sand is more difficult than the raw materials of ordinary artificial stone. In addition, the quartz stone plate has high hardness and the repairing process is also difficult for ordinary artificial stone plates. In general, there is a 1mm noise point on the surface of the quartz stone plate, which is normal. Exceeding this size or glaring impurities will be removed by the excavation method.

Cracking

Quartz stone is a product formed by vacuum high pressure molding. It has low resin content, high hardness and low toughness compared with ordinary artificial people. Although quartz stone countertops contain compounding agent for improving material toughness, they have relatively high impact resistance. It is necessary to avoid hitting the countertop, frequently hitting the countertop or pressing the suspended surface of the countertop with gravity, especially the weak parts on the countertop, such as near the cooktop, near the basin, at the corner, at the splicing site, in the middle of the large span cabinet, etc. . Generally speaking, all corners of the countertop design should be rounded with R25mm or more; the kitchen and the mouth of the basin should be applied to the straight edge of the machine; the front skirt and the rear block underwater retaining bar should be firmly bonded; Connection at the corner; cabinet installation should be horizontal; the maximum span of the table support should not exceed 600mm.

Connecting seam

Quartz stone has high hardness and low resin content, which is closer to natural stone than ordinary artificial stone. After the quartz stone is connected, there will be traces like the line at the splicing place, but it is not easy to see without careful observation, and it does not affect the appearance. In general, quartz stone products can basically achieve seamless splicing under the production of skilled quartz stone processing masters.
