Product introduction
The color is mostly black or gray-black Granite, with fine-grained compact blocks. Its compressive strength is about 3500~5000kg/cm2, and it has strong acid resistance, abrasion resistance, compression resistance and insulation properties. The distribution of basalt in the previous period was very extensive, and it was regular in almost every geological age. Well-known brands such as Fuding Black. Fuding basalt Stone ore in Fujian is a rare high-quality black granite basalt mine in the country. There are more than 500 natural stone processing enterprises with an annual mining capacity of nearly 100,000 m3. Orderly development and comprehensive utilization are the main directions of its sustainable development. Other natural stone varieties such as Mongolian black. In addition, basalt rock mining in Yunnan and Heilongjiang may also be under development.
Gabbro is also an important rock type of black granite, and its color is mostly black and pure. Some ornaments with black background and white dots pattern, stone varieties such as forest green (Hebei, Henan). The rock species are mainly gabbro and diabase. However, from the perspective of commercial purpose attributes, they all use the micron naming method. Basalt is extruded rock with a darker color. The mineral particles contained are uniform and small, and it is generally difficult to distinguish natural stone species with the naked eye, even with a magnifying glass. Basalt is the most widely distributed igneous rock. Most of the basalt is formed in the volcanic eruption. After the magma erupts, it encounters cold air and transforms the lava flow to quickly form. Some basalts are intrusive rocks. During the volcanic eruption, the magma did not spray out of the earth's surface, but was solidified by condensation inside the earth.
Diabase, a shallow facies rock of basic intrusive rock, is also an important rock type of black granite there. Black granite brands such as Taibaiqing. Taibaiqing is also called Shanxi Black, and in Japan it is called Night Rose. It can be studied with South Africa. The main rock type of Shanxi Black is diabase, the so-called Shanxi Black A. In China, the best quality black graphite is Shanxi Black Grade A, and the price Shanxi Black A contains the following actual mineral components: about 50% of plagioclase, with polyplate twin crystals developed; ordinary-pyroxene about 35%; A small amount of feldspar, about 5%; a small amount of minerals include hornblende, biotite, titanium magnetite and so on. According to the structure, it can be divided into three brands: large flower, medium flower and small flower, and the medium flower is the best. Similar varieties include Evergreen in Fengzhen, Heihe, Hebei, Pingshan, etc. Some Shanxi black plates have some golden dots on the polished surface. Many manufacturers don't like it, so the price of this quality board will be relatively low. If you like this kind of black natural stone with golden spots, and the price is reasonable, the quality of inspection is qualified, and it is not dyed, then you will buy it very cost-effective.
The first error area about pure black hemp: Some people think that all pure black hemp shells are the same material. Actually not, they may be very different in color, quality and price.
For pure black hemp, everyone knows Sutareboda, a black nanofiber produced in Sweden. This mineral has been developed for several years. Generally speaking, the most famous black graphite in Sweden is a kind of natural stone called ebony wood. This natural stone has strong hardness and high durability. After polishing, hit it with a hammer or chisel to make a metallic clang. Of course, this natural stone is also very expensive.
