At present, there are many kinds of stone materials used in the industry, and there are many kinds of stone classification methods. It is not only classified by stone rock ore; it is also classified by rock type and cause; it is also classified by stone craft business, rock mineral chemical property, stone hardness, basic shape, use and characteristics of stone. Of course, the classification of stone is not single-level, but can be multi-level.
According to the rock type, there are mainly three types of igneous rocks, sedimentary rocks and metamorphic rocks.
The business classification of stone is mainly composed of marble (cloud), granite (mathanite), slate, sandstone and gravel. It is mainly based on the hardness, processing property, application characteristics and products of stone. The characteristics of circulation to determine the classification of stone. The concept described here is just a stone commodity classification name, which is not rigorous in terms of the concept of academic professional name.
In the garden, according to the purpose of use, there are mainly decorative stone, cultural stone, stone for construction accessories, stone for mausoleum, stone for carving, stone for craft and so on. Mainly based on its use of industry, scope, use and other aspects.
In use, basalt (such as Fuding Black), diabase (such as Sichuan Tianquan Erlang Mountain Chrysanthemum Green), diorite (such as Tianquan Post Green, Baoxing Green), granite, etc. in igneous rocks are usually used. Gneiss in metamorphic rocks (such as Shandong white hemp, royal red) and mixed rocks (such as California Jinma, Hebei Pingshan Symphony), clastic rocks in sedimentary rocks (such as Guangxi cobblestone) and chemical sedimentary rocks are commonly known. For granite, the texture is generally hard [33]. Similarly, in the field of stone industry and commercial circulation, marble, dolomite, limestone, limestone, serpentinite, etc. are commonly referred to as marble, and the texture is generally soft].
Mini piston vacuum pumps are small-sized pumps that are designed to create a vacuum in various applications. These pumps are typically used in laboratory experiments, medical devices, and other industrial applications that require a small amount of vacuum. They are also commonly used in vacuum packaging machines, vacuum conveyors, and vacuum elevators. There are different types of mini piston vacuum pumps available in the market, including diaphragm, rotary vane, and piston pumps. Piston pumps are the most common type of Mini Vacuum Pump and are known for their high pumping speed and vacuum level. They are also highly reliable and durable, making them a popular choice for many applications. Electric mini piston vacuum pumps are the most common and are powered by an electric motor. In addition, mini piston vacuum pumps can be classified based on their flow rate, vacuum level, and pressure range. The flow rate refers to the amount of air that the pump can move per unit of time, while the vacuum level refers to the degree of vacuum that the pump can create. The pressure range refers to the range of pressures that the pump can handle, from atmospheric pressure to high vacuum. Overall, mini piston vacuum pumps are versatile and widely used in various applications due to their compact size, high pumping speed and reliability.
