What is the polishing effect of plastic polishing agent?

Mineral properties: pumice, also known as light stone, is a light-colored porous glassy rock. It is formed because the pressure drops sharply when the magma erupts, and the internal gas quickly escapes and expands. According to the shape and size of the jet, the name is different. Everything from the size of beans to the size of eggs is called volcanic slag, and those smaller than beans are called volcanic ash. Pumice is an acidic volcanic rock with hardness of 6 and density less than 1g/cm3, which can float on the water. Good thermal insulation; Porous and sharp walls. High chemical activity, strong adsorption, and obvious hydraulic cementing performance under the action of hydraulic activator. The chemical composition of pumice is unstable. Generally speaking, 50 1 accounts for 65%-75%, Al0I9%- 12%, and the sum of Cao, MgO and Fe2O3 is about 30%. Chemical composition of pumice (%): Asami: SiO2(62.67), Al2O3( 16.0 1), Fe2O3(2.32), CaO(6.44), MgO(3.72), and loss on ignition (0.89). Italian pomegranate volcanic ash: SiO2(46.0), Al2O3( 16.50), Fe2O3( 15.50), CaO( 10.0), MgO(3.0), and loss on ignition (5.0). Kedong County, Heilongjiang Province: silica (5 1.63), alumina (14.33), ferric oxide (6.27), calcium oxide (5.79) and magnesium oxide (6.54). Mineral uses: pumice has many uses, mainly used as natural lightweight aggregate, thermal insulation materials, fillers and so on. The main uses of pumice and volcanic ash in China are as follows. Building materials: natural lightweight aggregate for concrete. Such as exterior wall panels, floors and roof panels; Roof insulation layer and thermal insulation layer; Small hollow block; Heat-resistant concrete; Cement active mixed material; Preparing clinker-free cement; Building decorative materials department; Sound insulation and heat preservation materials. Chemical industry: grinding powder is used as filter, desiccant, catalyst and molecular sieve enzyme storage carrier in petrochemical industry. Plastics and filler industry: optical glass high-grade abrasive, plastic polishing agent, rubber filler, hard plastic filler, toothpaste, soap and other daily chemical fillers. Others: pesticide carrier, fertilizer control agent. The main uses of pumice and volcano abroad are as follows: building materials: lightweight concrete such as plastering mud and decorative board filler are 2% lighter than ordinary mixed soil and have a high fire resistance of 2%; Block bricks, building slabs, load-bearing components, hydraulic, thermal and bridge engineering building components; Railway ballast; Cement (using pumice as raw material). Grinding industry: glass and glasses grinding materials, soft metal and plastic polishing agents, kinescope and fluorescent screen polishing agents, polishing of metals (silver, copper, furniture, musical instruments) before electroplating, cleaning and polishing of wood, metal surfaces and stone materials. Fillers: metal tableware scouring agent, circuit board cleaning abrasive, soap, decontamination powder for work clothes washing. Daily chemicals: beauty materials, toothpaste, machine soap and cosmetic fillers. Petrochemical: molecular sieve. Rubber, asphalt, paper, paint and other fillers. , filter, pesticide carrier, ceramic glaze and enamel ingredients. Replacing light calcium carbonate as plastic filler. Thermal insulation material: mineral wool and its products are made of pumice as the main raw material and melted at high temperature for ceiling sound insulation. Minerals and ore types: Due to the different temperature and pressure of volcanic eruption, the mineral composition and composition are quite different. According to its composition, pumice deposits can be divided into basalt, rhyolite, andesite and trachyte deposits. China is rich in pumice resources, and pumice minerals are distributed in volcanic distribution areas from Heilongjiang in the north to Hainan Island in the south, with the northern region being the most abundant, with good quality and relatively new eruption age. The pumice resources in China are mainly basalt pumice, and rhyolite pumice is only found in Changbai Mountain and andesite, and only in Tianchi Lake in Changbai Mountain. Industrial requirements: Ore quality usually requires: loose bulk density.
