Which is better, natural marble and artificial marble
(1) natural marbleAdvantages: the pattern of natural, polished feel good, strong hardness, compared to artificial to wear a lot, not afraid of coloring, there are pores, will penetrate.Disadvantages: some radiation, natural marble brittleness, poor smoothness at the junction of love and marble and stone fracture is very obvious, can not be seamless, easy to breed bacteria, lack of flexibility, difficult to repair, the temperature variation can rupture.(2) artificial stoneAdvantages: no radiation, color and variety, relatively natural have a certain degree of flexibility, the reason for the connection between the stone and the stone is not obvious, a strong sense of the whole!Disadvantages: chemical composition of harmful substances, small hardness, fear of planning, afraid of hot, afraid of coloring.(3) how to distinguish artificial marble and natural marbleThere is a simpler way to identify man-made and natural marble: drop a few drops of dilute hydrochloric acid, natural marble blistering, artificial marble is weak or even bubble.
Natural marble and artificial marble, the characteristics of the two are different, can be based on demand, price, radiation, formaldehyde emission, etc..
Harm of inferior artificial marbleAt present in the market, commensurate with the local artificial stone containing benzene, formaldehyde, lead, organic acids and other harmful substances, this kind of plate have a common characteristic is the chemical pungent odor (especially the smell in the process, the color was larger) is not a natural chemical color, a pungent smell inferior man-made stone plate which contains formaldehyde and benzene in cutting, plate processing and forming device for consumption, will still be residual excessive formaldehyde and benzene, formaldehyde and benzene will be volatile in 3-5 years time is not continuous, benzene and formaldehyde and volatile heavy metals pollution will directly come into contact with food imports, this kind of harmful substances not only through the respiratory system and can be directly into the digestive system, toxic level and speed is more significant.Therefore, choose the outstanding quality of artificial stone is particularly important. Particularly in the winter in the north, home off the air in the indoor temperature is higher, more will accelerate this kind of "poison" solvents such as benzene and formaldehyde volatilization of more severe damage to human health!
Identification of inferior artificial marble method, we hope to be useful, summarized as follows:A look: the color of the visual sample is not pure turbidity, the appearance is not similar to plastic colloid feeling, no small pores on the back of the plate.Two smell: nose smell no pungent chemical breath.Three touch: touch the appearance of the sample silk feeling, no astringent feeling, no obvious upper and lower sense.The four row: with the nail plate appearance, no obvious scratch.Five touch: the same two pieces of percussion, not easy to break.Six check: check whether products ISO quality system certification, quality inspection report, there is no product quality insurance card and related security signs.
