What is the bleeding of quartz stone countertops

　　 Nowadays, many people's kitchen decorations use quartz stone materials to make countertops. Many people use it for a long time, and bleeding will occur. What is going on? Let's talk about it below.

　　 There are two kinds of quartz stone on the market in terms of production process, one is die-casting plate and the other is casting plate. Die-casting plate, as the name suggests, is processed through a series of procedures such as high temperature, high pressure, and high vibration. Because of the manufacturing process, its hardness and specific gravity are relatively high. Impermeability, crack resistance, heat resistance, and scratch resistance are all very good. The production process of the cast plate is improved from the original artificial stone production process, and the raw materials are directly poured into the mold and vacuumed after stirring. It has not been subjected to high temperature, high pressure, and high shock, and its density and hardness are relatively low. The impermeability, crack resistance, heat resistance and scratch resistance are relatively poor. Consumers who want to distinguish between cast plate and die-cast plate can start from the following aspects:

　　1. Hardness, the hardness of the cast plate is lower than 4, and the hardness of the die-cast plate is equal to or higher than Grade 5, Zhongxun quartz stone whose hardness is higher than Grade 5.

　　2, specific gravity (also called relative density, the ratio of the density of the substance to the density of pure H2O (999.972 kg/m3) at standard atmospheric pressure and 3.98℃), the specific gravity of the cast plate is less than 2 , Zhongxun die-casting plate has a specific gravity greater than 2.3, which fully meets the die-casting standards.

　　3, environmental protection performance, the casting plate is naturally solidified at room temperature, without any treatment, the residual chemical substances in the plate pose a hazard to the human body. The die-casting board is cured by OT curing and high temperature acceleration, and all the chemical components left in the board are processed at high temperature, which is an absolutely environmentally friendly surface material. Therefore, Zhongxun die-casting plate has always won the trust of consumers for its environmental protection.

　　4. Appearance, the particles of the casting plate are larger, and the particle distribution is uneven, and the back side is obviously less than the front side. The particles of the die-cast plate are uniform and evenly distributed.

　　The quality of quartz stone

　　1. In recent years, the market trend of quartz stone has increased greatly, and the domestic production of quartz stone Manufacturers are everywhere. So how do we distinguish the quality of quartz stone? The first is the raw material of quartz stone: the best domestic quartz mines are in Heyuan and Hainan in Guangdong, where the purity of quartz is high and there are few impurities. Countertops with high quartz content are not easy to wear because of the high hardness of quartz. Poor quality countertops have low quartz content. Some small manufacturers use broken glass instead of quartz, which looks very beautiful, and ordinary people don't know it. Next is the ratio of other materials. Poor quality countertops have more calcium powder, which will cause the countertops to be easily broken, high water absorption, and easy to absorb color and change color. The resin used for poor-quality countertops is also an inexpensive resin. The last is the production process. The equipment of small manufacturers is simple, and the press cannot achieve vacuum and high pressure, which will result in insufficient density of the table and pores. The simple equipment of the grinder will result in insufficient gloss of the table surface. Poor calibrating machine will cause uneven thickness of the table. At present, the domestic good quartz stone countertops are basically in Guangdong. There are currently two types of quartz stone plates; one is cast; and the other is pressed. The pressed plate is much denser than the cast.

　　Problems on the countertop

　　1. There are three reasons for cracks and cracks on the countertop:

　　a, the quality of the countertop plate is poor

　　b, users do not care and use incorrectly

　　c, the processing and installation of the countertop

　　2, the countertop splicing seam is obvious, and the countertops on both sides of the splicing seam The gloss is gone, and the color is gray and dark. The reason is that the splicing method and polishing method of the processing master are incorrect.

　　The method to solve the above problems and the requirements of the processing and installation process

　　1. The first reason for the cracks is the poor quality of the countertop. As mentioned above, there are not many here. said.

　　2, users do not care and use it incorrectly. To avoid local heating of the countertop, do not put the hot pot directly on the countertop, and there must be an insulation pad between the hot pot and the countertop. If there are oil stains such as soy sauce, oil, vinegar, etc. on the countertop, wipe it off as soon as possible, as it will bleed over time. Some countertop distributors will say to customers: their countertops do not bleed, it is all fooling people. At present, the domestic quartz stone countertops will bleed if they have not been specially treated, but the good-quality countertops have less bleed and are not easy to detect, and the poor-quality countertops have obvious bleeding. People should not stand on the countertop or be partially pressured by heavy objects. Do not wipe the dirt on the countertop with a cleaning ball, which will damage the gloss of the countertop.

　　3. The processing and installation technology and requirements of the countertop

　　a, the domestic countertop processing technology is generally compared with the south The north is more refined, and the south's splicing technology can completely seamlessly splice the white countertops, and the work is exquisite. The craftsmanship in the north is rough and not very particular about details.

　　b. Before installing the countertop, the cabinet must be leveled. The master who installs the countertop must not be sloppy, otherwise there will be cracks under the countertop and cracks in the rear water retaining part.

　　c. If the cabinet body is level, put the cushion strip and put it on the countertop, and still find that the countertop and the cushion strip are uneven, then the countertop is not flat when spliced u200bu200bin the processing plant. The reason for this is that the operating tabletop of the splicing table in the processing plant is not flat. After the joint is sewn with glue, the table and the operating table must be fixed together with fastening pliers. Then after the glue is cured, the table is also in line with the operation. The tabletop is also uneven. After such a countertop is installed, it will cause a basin hole on the countertop and cracks on the edge of the stove hole.

　　 After reading the introduction of the above article, I believe you should have some understanding of this issue. Hope to help you in your life.
