In home decoration, stone is widely used, such as: bay window countertops, door stone, decorative walls, bathroom countertops, cabinet countertops, etc. So how to choose decorative stone to beautify the room without affecting the health of the family? Next, let's take a look with the editor of FABULOUS Group.
Exterior:
The commonly used decorative stones are mainly marble and granite.
Generally speaking, marble has fine texture, changeable patterns, and bright color. It is easy to process and polish, but its hardness is low and its wear resistance is worse than that of granite. Mainly used for indoor floor, wall, window sill and column finish.
granite is characterized by compact structure, low water absorption, hard texture and high strength, especially its compressive strength can reach 1200-2500kg/cm². Since the main constituent minerals of granite have strong resistance to acid, they are extremely resistant to acid corrosion and alkali corrosion.
granite is not easy to be weathered and deteriorated, and the appearance and color can be maintained for more than a hundred years, so it is mostly used for exterior wall decoration. Because it has a strong corrosion resistance to acids in the air, it is harder and wear-resistant than marble, and in terms of durability is beyond the reach of other stones such as marble and terrazzo, it is an ideal natural stone for architectural decoration. Compared with marble, granite has fewer changes in color and pattern, but has more flexible changes in texture, and at the same time appears more solemn and classic in the overall feeling.
Quality:
The material of the stone should be uniform and complete to avoid problems such as dark cracks, black scars and chromatic aberration.
1. Pay attention to the composition of the stone and avoid excessively high levels of harmful substances such as iron sulfide, iron oxide, carbon and clay;
2. Pay attention to the radiation level of the stone;
3. Pay attention to whether the stone contains mineral components with high thermal expansion coefficient, thermal conductivity and electrical conductivity to avoid the danger of cracks, thermal conductivity and electrical conductivity.
Durability:
Should try to choose stone with uniform pore distribution, small pore size, low water absorption, high hardness and compressive strength. However, it should be noted that although the high specific stone has higher strength, it will increase the load of the structure and reduce the strength and earthquake resistance of the building.
