如何鉴别大理石的质量差异？

目前市场上石材产品质量良莠不齐，对于加工好的成品饰面石材，其质量好坏可以从四个方面来鉴别：一观，即肉眼观察石材的表面结构。一般来说，均匀的细料结构的石材具有细腻的质感，为石材之佳品；粗粒及不等粒结构的石材其外观效果较差。另外，石材由于地质作用的影响常在其中产生一些细微裂缝，石材较易沿这些部位发生破裂，应注意甄别。至于缺棱角更是影响美观，选择时尤应注意。二量，即量石材的尺寸规格，以免影响拼接。或造成拼接后的图案、花纹、线条变形，影响装饰效果。三听，即听石材的敲击声音。一般而言，质量好的石材其敲击声清脆悦耳；相反，若石材内部存在轻微裂隙或因风化导致颗粒间接触变松，则敲击声粗哑。四试，即用简单的试验方法来检验石材的质量好坏。通常在石材的背面滴上一小粒墨水，如墨水很快四处分散浸出，即表明石材内部颗粒松动或存在缝隙，石材质量不好；反之，若墨水滴在原地不动，则说明石材质地好。

Stone products on the market at present the quality good and bad are intermingled, the processed products facing stone material, its quality can be identified from four aspects: a view, namely the macroscopic observation of stone material surface structure. In general, the stone material of uniform fine structure has exquisite texture, is the best of stone; Coarse grain and differ the stone material of a structure its exterior effect is poorer. In addition, the stone material due to the influence of geological processes in which often produce some small crack, stone material the most easily along these place fracture, screening should be paid attention to. For lack of edges and corners are affec山东五莲石材高等菲t beautiful, especially when the choice should be paid attention to. Two quantity, namely the stone size specifications, lest affect splicing. After mosaics pattern, decorative pattern, line or cause deformation, affect adornment effect. Sounds of stone material knock three, namely. In general, good quality stone the knocking sound is ringing pleasing to the ear; On the contrary, if the stone within slight fracture or become loose contact between particles, as a result of weathering, tapping rough. Four test, which is a simple test method to check the quality of stone. Usually at the back of the stone drops on a small grain of ink, such as ink one soon, namely that exist within the stone loose particles or aperture, stone material quality is bad. Conversely, if ink drip五莲红花岗岩价格s to be not moved in place, explain stone material quality of a material is good.
