How to identify artificial stone and natural stone

How to identify artificial stone and natural stone Artificial stone, scientific name polymer mineral filled composite material (SOLIDSUR-FACE), the United States DuPont company invented in the 70's patented technology. The main components are methyl methacrylate (MMA), natural ore powder, natural pigments and other raw materials. The product is non-toxic, non-radioactive, non-sticky, non-porous, antibacterial, mildew proof, impact resistant, easy to maintain. , seamless stitching, arbitrary modeling and other advantages. As a replacement type of new countertop material, it has been widely welcomed by consumers.

Artificial stone has the color and texture of natural stone. Due to the different degree of stone crushing in the processing process, it is matched with different colors, so the color selection is much more abundant, and there is no difference in color and texture between the same types of artificial stone. Don't worry about the effect of the overall paving due to the existence of color validity. It has made great progress in moisture-proof, acid-proof, high-temperature resistant and patchwork.

However, compared to natural stone, after all, the natural textile path and texture are lacking. Because the same type of stone has the same color and texture as the stone, it has a slight sensation of vision. Artificial stone has strong plasticity, and can be designed according to different actual needs. Whether it is with the refractory board, waterproof board, crystal board, paint board or blister board, and even cement tile structure, can be very good.

However, with the continuous expansion of the market, as well as the delay in the introduction of relevant national quality standards, the number of artificial stone products in Wuhan is gradually increasing, and counterfeiting is also emerging. One is counterfeit well-known brands. Some manufacturers unite and use consumers to not understand the product, against the well-known brands on the market, by counterfeiting anti-counterfeit coding, parallel goods posing as genuine goods. The use of manufacturers to the market management is not strict, the warranty card does not give to the customer or do not paste anti-counterfeiting, gold medals and other means to achieve the purpose of deception; one is to directly use the consumer's greed and cheap psychology. Some unscrupulous manufacturers in the local and foreign countries did not apply indigenous methods. In the case where the quality of the products was not overridden, industrial resins replaced methyl methacrylate and calcium carbonate replaced aluminum hydroxide, hitting the market at extremely low prices. Nowadays, most of the artificial stone that is sold at a retail price of more than 300 yuan per meter on the market has no quality and after-sales guarantee, and it is easily broken, deformed, faded, and even toxic.

Another factor that hinders the use of artificial stone is human factors. Because the manufacturing process of artificial stone is very different, performance and characteristics are not exactly the same, so the above mentioned advantages are not necessarily the performance of the artificial stone you have purchased. The artificial stone imported on the market at present is better in performance. For example, the imported artificial stone allows scratches on the surface with sandpaper, which is no longer obvious to the user, and many domestic artificial stones obviously do not work. The more they are polished, the worse they are. To buy artificial stone, it is best to take a sample plate for bad performance tests, such as pouring soy sauce or oil and carrying out caries testing.

Authentic: generally have ISO series international quality system certification and related inspection report, using pure methyl methacrylate and aluminum hydroxide as raw materials, non-toxic and tasteless, good processability, not easy to break, using high-grade or imported pigments, visual color purity , natural, texture, large-scale imported equipment assembly line production, stable quality, small batch color difference, delicate material particles, hand touch with silk, good UV resistance, no fading during use, standard sales network, service Guarantee, product security signs, maintenance manuals and product quality assurance, 10 to 15 years commitment to quality assurance, the market price of 400 yuan -800 yuan / m or so, some imported artificial stone prices higher.

Bad product: Low-grade industrial resin and calcium carbonate are used as raw materials, toxic odor, poor processability, easy to break and deform, low-grade pigments are used, visual color is dark and turbid, surface has plastic gum texture, and small equipment or soil equipment is the main product. Unstable quality, large batch color, large particle size, rough hand feel, poor light fastness, generally begin to fade in one or two years, generally rely on small store sales, market price confusion, generally less than 400 yuan / meter , In the specific purchase process, you can refer to the following tips:

A look: The visual color of the sample is not cloudy, the surface has no similar plastic gum texture, and there are no small pores on the opposite side of the plate.

Two smells: No smell of nasal odors, chemical smell.

Three touch: hand touch the surface of the sample has a sense of silk, no astringent, no significant level of unevenness.

Four strokes: The surface of the sheet was scratched with a fingernail without any scratches.

Five touch: The same two samples hit each other, not easy to break.

Six checks: Check whether the product has ISO quality system certification, quality inspection report, whether there is product warranty card and related security signs.
