Cieme artificial stoneSmall make up to tell you how to identify artificial stone
Artificial stone is a kind of synthetic decorates material. According to the different binder used, can be divided into organic and inorganic kind of artificial stone kind of artificial stone. According to its production process is different, can divide again for polyester type artificial marble, complex artificial marble, silicate salt type artificial marble, sintering type artificial marble four types.
In four kinds of man-made stone decoration materials to organic class (polyester) the most commonly used, its physical and chemical properties are the best.
Marble is a kind of high-grade decorative materials, when the choose and buy must discreet, so as not to waste money. Identify the appearance quality of the marble are available from the following several from his hand.
(1) the judgement pattern color Under the condition of the light is enough, will have to choose a good plank and the same to the choose and buy other marble plank flat on the floor at the same time, standing in the distance they are 1.5 m careful visual inspection. Require the same marble plank tonal pattern of fundamental harmonic.
(2) check the surface defects Under the condition of the light is enough, the plate is flat on the ground, standing behind the marble plank Lin to observe invisible defects that no defects; Standing in the sheet from Lin visible in 1. Sin no obvious flaws as no obvious flaw; Standing from plate 1. Sin place clearly see defects that have defects. Defects of concrete observation I plate buckling; Plate surface crack, sand holes, different flecks, stain and concave phenomenon exists. If determine the above several defects without the plate as the classy article, at the same time sheet is not allowed to have lack of positive edge dro Angle defect; If the above defect is not obvious at the same time also no obvious lack of edge Angle, then can maintain the plank for level 1; If there were a few defects, but does not affect the use, only 1 sheet and positive director is not more than 8 mm, width is not more than 3 mm short or long and wide edges are not greater than 3 mm off Angle, can judge the plank for qualified products. Plate and damaged during transportation, loading and unloading, and can be felt (for broken plate) or repair (for potholes or pitting on the surface of the defects, edges and corners). But felt, repair after positive there is no obvious trace, color to color close to positive.
(3) the check mark Marble plank tag order is: the naming, classification, grade, standard, specification size Name order for marble plank: waste material place of origin, name of decorative pattern and tonal characteristics, marble (code-named M). Marble plate is divided into two categories: general type plate (code-named N) : long for a square or rectangular plate; Heterotypic plates (code-named S) : for other shape of the plate. Marble plate has three levels: classy article (code-named A), grade A nonconforming product (code-named B) and (code-named C). Grading is based on the plate size to allow partial differential, flatness tolerance limit of tolerance, Angle tolerance limit tolerance, appearance quality and the mirror luster.
