Health hazards:
Too much calcium carbonate on inferior countertops may affect the health of digestive tract.
"Cabinet countertops are made of artificial stone, quartz stone and metal. What are the health risks? " This is a misunderstanding of many people. According to Yang, the manager of the cupboard North Daming Palace store, "In simple terms, artificial stone is formed by resin and calcium carbonate; Quartz stone is silica plus calcium carbonate; Metal countertops are mainly made of stainless steel. At present, the mainstream materials of the countertop are quartz stone and artificial stone, and the metal utilization rate is very low. "
Why are inferior countertops also harmful to the environment? According to Yang, calcium carbonate, commonly known as limestone, has certain corrosiveness. In order to reduce the cost, inferior artificial stone and quartz stone countertops will increase the content of calcium carbonate. If food comes into contact with the desktop containing more calcium carbonate for a long time, it will cause some pollution, and people will have some influence on the digestive tract after eating it. Moreover, inferior stainless steel countertops will also have hidden dangers of heavy metal pollution. Not all steel products are the same, otherwise the grades of steel products will not be divided into food grade and medical grade.
Material comparison:
The shape of artificial stone is changeable, and quartz stone is resistant to wear and high temperature.
Wang Jiantao, chairman of Bobenka Cabinet, said that when introducing cabinets, merchants would say that the countertops are Shi Ying or artificial stone countertops. What's the difference between them? In fact, quartz stone also belongs to artificial stone, belonging to a large category, all of which are artificial stones made of equipment. However, it is customary in the industry to call ordinary calcium powder board or aluminum powder board, composite acrylic and other stones artificial stones, which are divided into quartz stones.
Advantages and disadvantages of artificial stone countertops:
Acrylic stone is the main artificial stone countertop material, with beautiful processing and modeling, mainly the curved back to block water, absolutely seamless splicing, special-shaped processing, quartz stone can not reach; In addition, the toughness of acrylic stone is better than quartz stone, especially pure acrylic is the best.
Advantages: seamless splicing, changeable shape, diverse and soft colors, and easy to repair problems. If it is used for too long, it can be as bright as new after re-polishing;
Disadvantages: Hardness is slightly worse than quartz stone. If rough objects rub on the table, it is easy to destroy the brightness. Composite acrylic artificial stone can resist high temperature to about 90 degrees, and pure acrylic can resist high temperature to 120 degrees, but it is not allowed to contact overheated objects for a long time.
Advantages and disadvantages of quartz stone countertops;
Quartz stone is superior to acrylic stone in hardness and wear resistance, and has better heat resistance. However, neither acrylic stone nor quartz stone can directly put hot pot on the dining table, and thermal expansion and cold contraction will lead to changes in local molecular structure. Whether it is quartz stone or acrylic stone, if you put high-temperature objects directly on the countertop without using pot mats, the surface that contacts high-temperature objects will be different from the bright parts of other countertops for a long time.
Advantages: Compared with ordinary artificial stone, it has high temperature resistance and scratch resistance;
Disadvantages: modeling is simple, modeling is not complicated, and problems and bumps are not easy to fix. Due to the high hardness and density, seamless splicing is impossible.
Shopping tips:
Do a "cross-check" experiment when shopping.
Ask for a test report
Whether it is acrylic stone or seasonal stone, the composition of the material determines the quality, and quartz stone is not superior to artificial stone. Users should compare manufacturers and product components as much as possible when purchasing stone materials. Try to ask the seller to show the test report and after-sales certificate of the product.
Hu, the general manager of Debao Dizzani Cabinet, suggested that when consumers buy, they can do a "cross" experiment on the countertop samples of two materials, and draw the smooth surface of another sample with the sharp corner of one sample to compare which countertop has deeper scratches and which is softer and has higher calcium carbonate content. It is recommended to choose carefully. Quartz stone is harder than ordinary artificial stone, and quartz stone countertops feel cooler, while ordinary artificial stone countertops feel milder.
