    Core tip: lime mud, also known as lime mud matrix, or gypsum plaster It is one of the structural components of carbonate rock, and is a kind of sediment composed of muddy calcium carbonate fines or crystals It is widely used in daily life Stucco 1 In modern sediments, most of the stuccos are acicular aragonites deposited by chemistry or biochemistry The average length of the crystal is 0.001-0.004 mm Some of them are fine debris formed by biological skeleton (especially calcium algae) or other carbonate particles through mechanical crushing and abrasion or biological corrosion Its components Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: plaster (lime mud), also known as plaster matrix, or plaster of Paris It is one of the structural components of carbonate rock, and is a kind of sediment composed of muddy calcium carbonate fines or crystals It is widely used in daily life Stucco 1 In modern sediments, most of the stuccos are acicular aragonites deposited by chemistry or biochemistry The average length of the crystal is 0.001-0.004 mm Some of them are fine debris formed by biological skeleton (especially calcium algae) or other carbonate particles through mechanical crushing and abrasion or biological corrosion Its composition is high magnesium calcite or low magnesium calcite or aragonite, which mainly depends on the mineral composition of skeleton or particles; there are also plasters which are directly composed of plankton individuals, such as pelagic coccidian plasters, radiolarian plasters and coccolith algae plasters Most of the particles are less than 0.005 mm After diagenesis and consolidation, the limestone or micrite limestone and microcrystalline limestone are formed 2、 The application of stucco as a kind of building material began in the Paleolithic age In its long practical application process, especially after the rapid development of modern industrialization, the traditional "Plaster" material has undergone tremendous changes However, the core components can still be classified into the following items according to their functions and functions: aggregates are also called fillers, which mainly play a filling role in the components of plaster Some aggregate materials will directly or indirectly affect the performance characteristics of mortar components due to their unique physical structure characteristics, such as fire resistance, wear resistance, respiration, humidity regulation and coloring, etc The traditional mortar aggregate mainly includes: colored soil, loess, diatom soil, shell, ash, glutinous rice soil and so on As the name suggests, the aggregate mainly plays the role of skeleton in the components of mortar The strength, compressive strength, wear resistance, film thickness and texture of plaster are directly related to the type, size and characteristics of aggregate The types of stucco aggregate mainly include: special aggregate: Perlite vermiculite zeolite natural sand / gravel: river sand, mountain sand coral sand shell powder Opal and other artificial sand: Quartz color glaze sand porcelain, chalcedony grain glass bead and other sticky materials The function in the components of plaster is to bond The bond fastness of plaster mainly depends on the selection of bonding materials, and directly determines the comprehensive performance index of the finished plaster The traditional types of binder include seaweed paste, gingko paste, natural gum, hydrated lime, special cement, gypsum, herbal refined resin and other reinforced mortar components The main role of the reinforced mortar is to play a role of binding and coupling, improve the tensile strength of the mortar, enhance the elasticity and anti shrinkage, so that the mortar facing layer is not easy to crack The types of reinforcement materials include: plant fiber, hemp knife (hemp, jute, grass hemp, flax), paper reinforcement, wood fiber, mineral fiber, synthetic fiber and other pigment pigments, which play a role in the color matching of plaster components The types of pigments commonly used for mortar color matching mainly include: natural inorganic minerals: hercynite, stone yellow, red sand, laterite, clay, kaolin and other iron oxide composite pigments, etc 3 Cyan mortar, also known as Tibetan cyan mortar, is widely spread in the late Ming and early Qing Dynasty, with a small amount of mining, so the finished product is very rare The mud is dark purple and gray Because of the special touch and full of particles, players like to call "shark skin", which is very difficult to find a super grade mud mine The mud of argillaceous lime is loose, high in iron content, extremely large in tension, not easy to change and collapse, but not enough in viscosity The melting point of iron oxide is easy to appear in the firing process The mud with more lime, sand jumping and impurities should be strictly and carefully picked, and the temperature of the kiln is extremely high After firing, the double porosity structure is obvious, the air convection is smooth, simple and elegant, the old taste is full, and it is unique in the Ming Dynasty purple sand material charm It has a strong sense of sand without scratching Its color is purple like gray It is heavy, solid and uncompromising It is like a tough guy style, which is very easy to identify The kiln temperature is about 1200 ℃, and the shrinkage ratio is 13% The teapot of Chong Ming is made of lime mud It has a cold appearance and a hot heart Chong Ming is passionate and bold, mellow and strong, sweet and sweet It's a hero in the pot It's suitable for making black tea, green tea, oolong tea, etc Home of coatings focuses on the news and information of coatings, diatom mud, paint coatings, coating process, fire retardant coatings and coatings, paint coatings, coating process, decoration knowledge and decoration effect map of fire retardant coatings,
