Differentiate artificial stone

Artificial Stone material is a synthetic decoration materials. According to different, used binder of artificial stone can be divided into organic and inorganic kind artificial stone two kinds. According to the production process is different, can divide again for polyester Artificial Marble, complex artificial marble, tsino salt type artificial marble, sintered artificial marble four types.
Four kinds of artificial stone decoration materials, organic class (polyester), the most common thing Richard, chemical properties also had better.
Marble is a kind of high-grade adornment material, when the choose and buy must discreet, lest waste gold money. Identify marble exterior quality from the following several items from his hand.
(1) the judge in a good light tonal pattern, will have elected under the condition of good plank and other want a choose and buy with the marble and flat on the ground, stood in the distance they 1.5 m place careful visual. Requirements and batch of Marble Slab decorative pattern is tonal should basic harmonic.
(2) check surface defect in a well-lit conditions, will plank uncrossed on the ground, standing at a distance of marble Lin place observation invisible defect think no defect; Standing in Lin place from plank in 1 is not obvious flaws in library functions like sin; for no obvious flaw Standing in the distance plank 1. Obviously the defects of library functions like sin place that flawed saw. 'specific observations of defects have I plate wrpping; Plank surface crack, sand holes, or different spots, stains and cave phenomenon exists. If convicted the above several defects not for classy article, also is plank not lack edges are positive plank drop horn defect; If above defects not obvious also no obvious lack of edges, so can drop horn that this plank as primary product; If there is that several defects but do not affect again use, and plank positive only 1 8mm, director not greater than 3mm wide not greater than lack edges or length and width are no greater than 3mm drops horn, may judge the plate for qualified products. Plank in the transportation, loading and unloading process and touch bad, can undertake bond (against rupture plank) or repair (on the surface of angular defect, certainly some pits or hemp dot). But felt, repaired positive is not permitted, color to trace evidence with positive color close.
(3) to examine mark marble mark order: naming, classification, size, grade, standard marble named order: waste material origin place names, decorative pattern is tonal characteristics, code-named the name, marble (M). Marble is divided into two categories: plate type (doppler code-named N) : for a square or long quadrate plate; Alien sheet (S) : code-named for other shapes of the plank. There are three levels: marble plate sessions (code for A), grade A (code for B) and qualification (code for C). Hierarchies basis is the size of allowing partial plate flatness allow limit bad, tolerance, Angle allow limit tolerance, exterior quality and mirror surface gloss.
