Volcanic rock commonly known as pumice or porous basalt, also known as pumice rock, it is a dense porosity of molten magma condensed by volcanic eruption glassy lava, the porosity volume accounted for more than 50% of the volume of the rock.

Mica is a kind of rock forming mineral with hexagonal lamellar crystal shape and is one of the main rock forming minerals. Mica crystal has a layered structure inside, so it is lamellar crystal, mainly hexagonal lamellar crystal. Characteristics are insulation, high temperature resistance, the most used in industry is sericite, widely used in paint, paint, electrical insulation and other industries.

Light stone, also known as pumice or pumice rock, is named because of its more pores and small volume weight (0.3-0.4) and can float in water. Lite is a kind of porous, light glassy acid volcanic extrusive rock, its composition is equivalent to rhyolite. The surface of light stone is rough, the particle bulk weight is 450kg/m3, the loose bulk weight is about 250kg/m3, the porosity is 71.8-81%, and the water absorption is 50-60%.

Perlite is a commonly used building insulation material in the construction industry and is often used in external wall insulation. Perlite has strong water absorption and is easy to seep water and gain weight, and the outer layer needs to be a waterproof coating when it is usually used for external wall insulation.

iron dust, which is an aggregate of iron particles with a size of less than 1mm, is the main raw material for powder metallurgy. According to the particle size, it is traditionally divided into five grades of coarse powder, medium powder, fine powder, micro-fine powder and ultra-fine powder. Iron powder composed of particles with particle size in the range of 150~500μm is coarse powder, particle size in the range of 44 ~ 150μm is medium powder, 10 ~ 44μm is fine powder, 0.5~10μm is extremely fine powder, and less than 0.5μm is ultra-fine powder.

Pine bark can adjust the acidity and alkalinity of the soil, provide nutrients for the growth of plants, and pine bark planting can maintain good water permeability and air permeability of the soil.

Uses of kaolin Pure kaolin has high whiteness, soft quality, easy to disperse suspended in water, good plasticity and high cohesiveness, excellent electrical insulation properties; It has good acid solubility, low cation exchange capacity, good fire resistance and other physical and chemical properties.

Volcanic stone (volcanic rock or pumice) is a kind of glassy lava with dense pores formed by the rapid expansion of internal gas due to the sharp reduction of pressure after the sudden cooling of magma during the volcanic eruption. The pore volume accounts for more than 50% of the rock volume. It is called pumice because of its many pores, light weight and ability to float on the surface of the water. It is characterized by high strength, heat preservation, heat insulation, sound absorption, fire protection, acid and alkali resistance, corrosion resistance, and no pollution, no radioactivity.

Its pure kaolin is white, delicate, soft soil, with good plasticity and fire resistance and other physical and chemical properties. Its mineral composition is mainly composed of kaolinite, Eloite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin is widely used, mainly for paper making, ceramics and refractory materials, followed by paint, rubber fillers, enamel glaze and white cement raw materials, a small amount of plastic, paint, pigments, grinding wheels, pencils, daily cosmetics, soap, pesticides, medicine, textile, petroleum, chemical, building materials, national defense and other industrial sectors.

Mica is a rock-forming mineral with a hexagonal lamellar crystal shape. Characteristics are insulation, high temperature resistance, the most used in industry is sericite, widely used in paint, paint, electrical insulation and other industries.
