Stone Testing
Stone materials is generally divided into two types: artificial Stone materials and natural Stone materials. Natural Stone materials is further classified into slate and granite based on its physical and chemical properties. Artificial Stone materials is divided into water-washed Stone materials and synthetic Stone materials according to the manufacturing process. The main testing items for Stone materialss include compressive strength, freeze-thaw cycle, bending strength, density, water absorption rate, glossiness, wear resistance, acid resistance, radioactivity.

Stone materials Testing
Stone materials is generally divided into two types: artificial Stone materials and natural Stone materials. Natural Stone materials is further classified into slate and granite based on its physical and chemical properties. Artificial Stone materials is divided into water-washed Stone materials and synthetic Stone materials according to the manufacturing process. The main testing items for Stone materialss include compressive strength, freeze-thaw cycle, bending strength, density, water absorption rate, glossiness, wear resistance, acid resistance, radioactivity.
Testing items
Hardness, density, haze, yellowness, whiteness, Mullen viscosity, sulfurization curve, apparent density, compressive strength, ash content, volatile matter, dimensional change rate, water vapor transmission coefficient, durability, brittleness, toughness, setting time test, stability test, strength test, bulk density, flame retardancy test, void ratio test, compressive strength test, tensile test, bending test, consistency test, heat resistance test, etc. Formula analysis, component identification, content analysis, component comparison, component testing, etc.
