A, tonal

Natural decorative stone in addition to the need to consider the color selection, but also consider the function of the building.In the home, the adornment appropriate of sitting room and bedroom chooses slant warm tonal, already showed warm, comfortable emotional appeal, and the adornment appropriate that uses at toilet, kitchen chooses element quietly elegant clean slant cool tonal, already showed cleanness and sanitation.

Second, the intention of decoration and environmental impact

Due to the use of natural stone decoration parts are different, so the selection of stone types are different.Used for outdoor building decoration, need to withstand water vapor, wind, rain and sun, granite because it does not contain carbonate, water absorption rate is small, weathering resistance is strong, the best choice of various types of granite stone;The decorative stone used for hall ground decoration requires its stable physical and chemical properties and high mechanical strength. Granite stone should be the first choice.Used for wall and household bedroom ground decoration, mechanical strength is a little poor, has been chosen to have a beautiful design is marble.

Three, identify the quality of decorative stone

Processed finished product facing stone, its quality can not be identified from the following four aspects;

(1) view, that is, naked eye observation of the surface structure of stone.Generally speaking, the uniform material absorption structure of the stone has a delicate texture, the best stone;Coarse grain and the stone material with unequal grain structure its exterior effect is poorer, mechanical mechanical property is not even also, quality is a bit poor.Additional, natural stone material often produces among them as a result of the effect of geological action a little micro crack.Stone is the most easy to crack along these parts, should pay attention to remove.As for the lack of edge less Angle is affecting beautiful, especially when choosing should pay attention to.

(2) the amount, that is, the size of the stone rules, so as not to affect the splicing, resulting in the group, pattern, line deformation after the splicing, affect the decorative effect.

(3) listen, that is, listen to the sound of stone percussion.Generally speaking, good quality, uniform internal density and wireless micro-crack stone, its tapping sound clear and pleasant;On the contrary.If the microscopic crack exists inside the stone because of weathering causes the contact between particles to become loose, then the knocking sound is rough.

(4) try, that is, simple experimental way to test the quality of food materials, usually on the back of the stone drop on a drop of ink, if the ink quickly four scattered leaching, that is, the internal particles of the stone is loose or there is a micro-crack, stone quality is not good 'on the contrary.If the ink water droplets in the original place is not moving, it shows that the dense texture of stone is good.
