The scientific name of the stone is limestone, is the most widely distributed in the diagenesis of a kind of rock, all over the country have output, the main components for calcium carbonate and clay, silicon oxide, magnesium oxide, etc..When the silicon oxide is high, the hardness of the slates is high, the bulk density of the slates is 1000~2600 kg/m3, the compressive strength is 10~100 MPa, the material is soft and easy to weathering.
Green stone is easy to split into small area of the thin board, used in the garden in the past, roof tiles, etc.Because of its primitive simplicity and nature, some interior decoration will use it for local wall decoration, the effect of returning to plain and true is quite popular.Green SLATE to take the natural effect of splitting, the surface is generally not polished, also not stressed, as long as there is no crack can be used to help select.
The stone is dense in texture, medium in strength and easy to be processed. It can be cut into thin plates or strips by simple technology. It is an ideal building decoration material.It is used for building wall skirt, floor paving, yard railing (board) and step lamp, which has the unique style of ancient architecture.
The color of the commonly used green SLATE is bean green and deep bean green and green with grayish white crystal particles and so on.The different processing technology of green SLATE pattern is divided into coarse hair panel, fine hair panel and cutting axe board.Can also be processed into a smooth surface (polished) plate according to the building intent.
Blue stone cultural plate is a new type of senior decorative materials, pure natural no pollution no radiation, good quality, durable, cheap and good in quality.The rich stone culture makes it have high ornamental value and collection value.
