Observe the appearance:
Surface flatness: The surface of high-quality quartz stone sink should be smooth and flat, without obvious roughness, bubbles, cracks or flaws. You can observe the surface of the sink from different angles to check whether there is uneven light refraction, if so, the surface may be uneven.
Color and pattern: color should be uniform, pattern distribution natural, clear, no obvious color difference, spots or miscellaneous. If the color of the sink surface is different, the pattern is fuzzy or there are obtrusive color blocks, the quality may be poor.
Edge treatment: The edge of the sink should be polished smooth, no burr, sharp edge, and even chamfering, so that it is not easy to cause accidental damage during use, and the fit degree with the table is better after installation.
Check physical properties:
Hardness test: The quartz content of the quartz stone sink should generally reach about 93%, the hardness is very high, and the Mohs hardness can reach about 7.5, which is much higher than the knife and shovel commonly used in the kitchen. The steel knife or other hard objects can be used in the unobtruded part of the sink, if there is no scratch, indicating high hardness and good quality, but it should be noted that this method may cause damage to the sink, and is only suitable for a small range of tests.
Impact test: gently tap the sink, listen to whether the sound is crisp and pleasant, if the sound is dull, there may be dark cracks or uneven material inside. You can also try to gently drop small objects from a certain height into the sink to observe whether the sink is prone to damage, cracking, etc., but pay attention to control the intensity to avoid damage to the sink.
Water absorption test: Drop a few drops of water on the surface of the sink and observe the state of the water droplets. The water absorption rate of high-quality quartz stone sink is very low, the water droplets will form water beads on the surface, and the water will not penetrate for a long time. If the water droplets are quickly absorbed or form water stains, it means that the density of the sink is poor and the quality is not good.
Evaluate chemical properties:
Corrosion resistance test: Use a small amount of common kitchen acidic or alkaline substances, such as white vinegar, lemon juice, baking soda, etc., drop on the surface of the sink, stay for a period of time and wipe it off, and observe whether the surface of the sink has discoloration, corrosion, foaming and other phenomena. If there is no change, it indicates that the corrosion resistance of the sink is good.
Understanding of antibacterial performance: high-quality quartz water tank has certain antibacterial function due to its dense non-porous structure. You can check whether the product has the relevant antibacterial test report or certification to understand its antibacterial performance.
Check material composition and thickness:
Quartz stone content: The higher the content of quartz stone in the quartz stone sink, the better the quality is usually. In general, the qualified quartz stone sink quartz stone content should reach at least 93%, can require businesses to provide product composition test reports or relevant supporting documents.
Sink thickness: The standard quartz stone sink thickness is generally between 12-15mm, the thickness is too thin may affect the service life and durability of the sink, in the purchase can be measured or ask the merchant sink thickness.
View accessories and installation:
Sink accessories: Check whether the faucet, drainer and other accessories equipped with the sink are complete and the quality is good. The material of the accessories should be corrosion resistant, durable, smooth surface, no rust, damage and so on. Good accessories can enhance the overall use experience and life of the sink.
Installation method: Understand whether the installation method of the sink is reasonable and firm, whether it is easy to install and disassemble, and later cleaning and maintenance. For example, the installation method of the lower basin is easier to clean than that of the upper basin, but the installation difficulty is also relatively large, and it is necessary to ensure that the installation process meets the requirements.
Learn about brand and after-sales:
Brand reputation: Choose a well-known brand of quartz stone sink, usually these brands in the production process, quality control and after-sales service are more guaranteed. You can understand the reputation and credibility of different brands through network evaluation, friend recommendation, home forum and other ways.
After-sales service: Ask the merchant about the after-sales service policy of the sink, including the warranty period, the warranty scope, the maintenance method, whether to provide on-site service, etc. Good after-sales service can provide users with timely and effective solutions when problems occur in the sink
