How do consumers identify the true and false quartz stone countertops?

The countertop is the most eye-catching feature of any cabinet system. Whether it's smooth, textured, or in a bold color, it's the first thing people notice when they look at your kitchen. Many dealers take advantage of this by using low-quality materials to create fake countertops, which not only deceives customers but also disrupts the overall quality and reputation of the cabinetry industry.

When it comes to home renovation, the kitchen is always a top priority. Custom-made whole cabinets have become increasingly common, with prices ranging from tens of thousands to even millions of yuan. In the home improvement market, whole cabinets are now one of the most popular and essential furniture items for most households. However, despite their popularity, many consumers still lack a clear understanding of what goes into them — especially when it comes to the countertop.

Countertops make up a significant portion of the total cost of a cabinet. For example, a cabinet priced at 2,800 yuan might already include an artificial stone countertop that costs over 1,100 yuan. But the quality of domestically produced artificial stone varies widely. Some lower-quality options can be as cheap as 200 to 300 yuan per meter. This wide price range gives retailers plenty of room to inflate profits, often at the expense of the customer’s satisfaction and long-term value.

Currently, quartz stone countertops are among the most popular choices. However, consumers should be cautious of unscrupulous businesses that may try to substitute fake quartz for real ones. Visually, genuine and counterfeit quartz stones can be nearly identical, making it hard to tell the difference at first glance. But there are key differences. Real quartz countertops are made up of about 94% natural quartz and 6% resin, giving them high hardness and excellent heat resistance. They can withstand temperatures up to 300°C without damage. On the other hand, fake quartz is often made with marble powder and more resin, which makes it softer, more prone to warping, and more likely to burn or discolor under high heat.

To help you identify real quartz from fake, here's a simple test: drop a small amount of toilet bowl cleaner onto the surface. If bubbles appear, it's likely a fake. Real quartz will never react this way. Also, to ensure you're getting the real deal, pay attention to the installation process. Legitimate brands typically ship both the cabinets and countertops directly from the factory and install them together. If the countertop is installed separately after the cabinets are in place, or if it's locally fabricated, there's a higher chance it could be a counterfeit product. Always ask questions and verify the installation method before finalizing your purchase.

Check Valve

The check valve is used in the piping system, its main function is to prevent the backflow of the medium, prevent the pump and its driving motor from reversing, as well as the release of the medium in the container.


Check valves can also be used to feed pipes where the pressure may rise to exceed the pressure of the main system. Check valve according to the different material, can be applied to a variety of media pipeline.


The check valve is installed on the pipeline, which becomes one of the fluid components of the complete pipeline. The opening and closing process of the valve disc is affected by the transient flow state of the system in which it is located. In turn, the closing characteristics of the disc have an effect on the fluid flow state.
