Product Description Calcium Carbonate(CaCO3) FOR PAPER COATINGCalcium Carbonate(CaCO3), is used for making cement, ceramics, lime, calcium salt, toothpaste, dyes, pigments, mineral water, artificial stone, putty, neutralizer, catalysts, filler, medicine, etc. It can be used as filler in rubber, plastic, paper making, putty, primer, paint, ink, and other industries. It is widely used in organic synthesis, metallurgy, glass, and asbestos production. It can also be used as a neutralizer of industrial wastewater, an antacid for gastric and duodenal ulcer disease, the antidote for acidosis, a sulfur dioxide remover in waste gas containing sulfur dioxide, a dairy feed additive and an anti-adhesion agent of linoleum, etc. It can also be used as raw material for toothpowder, toothpaste, and other cosmetics.Product DescriptionAppearance and properties: odorless, tasteless white powder or colorless crystal.Melting point (oC):825 (decomposition)Boiling point (oC): no dataRelative density (water =1):2.70-2.95Solubility: insoluble in water, soluble in acid.White powder, tasteless and odorless. There are two forms: amorphous and crystalline. The crystalline form can be divided into an orthorhombic system and a hexagonal system, which are columnar or rhombic. The relative density is 2.71. It decomposes at 825 ~ 896.6 oC, the melting point is 1339 oC, and the melting point is 1289 oC under 10.7Mpa. Insoluble in water and alcohol. It dissolves in acid and emits carbon dioxide at the same time, showing an exothermic reaction. Also soluble in ammonium chloride solution. It is stable in the air and has a slight moisture absorption ability. It has good covering power.Preparation methodCalcium hydroxide reacts with hydrochloric acid to obtain calcium chloride, which is decolorized by activated carbon and filtered to remove impurities. Calcium chloride is carbonized with carbon dioxide in the presence of ammonia to obtain calcium carbonate, which is then crystallized, separated, washed, dehydrated, and dried to obtain pure calcium carbonate.Transportation and storageIt has a strong irritant effect on the eyes and a moderate irritant effect on the skin. Store in a cool and ventilated warehouse. It should be stored separately from acids, ammonium salts, etc. Do not hit, roll, or fall during handling. Pay attention to personal protection during sub-loading and handling. Purpose1. Used as flour treatment agent, transport agent, stabilizer, yeast nutrients, and a mineral nutrition enhancer.2. Used as a nutrient fortifier for feed.3. It is a filling material for rubber, which can make rubber bright color, with high elongation, high tensile strength, and good wear resistance. Also used as artificial leather, wire, PVC, paint, ink, and paper industry filler. When used to produce microporous rubber, it can make it evenly foaming.4. Used as an analytical reagent, and as a reference reagent. Emission spectrum analysis of sample flux, volatile additives. Also used as silicon single crystal slicing glue, thick film capacitive material, optical glass, and pharmaceutical industry raw materials.5. As a white filler for plastics, paper, rubber, paint, ink, etc., it is one of the most widely used filler6. Used for the manufacture of powder, powder, gouache, rouge, and other raw materials, powder cosmetics are used as a flavor mixing agent, but also mainly used for toothpaste as a friction agent, toothpaste is a hard abrasive. For the preparation of cement, ceramics, lime, calcium salt, toothpaste, dyes, pigments, mineral water, artificial stone, putty,neutralizers, catalysts, fillers, and pharmaceuticals. it can be used as a filler in rubber, plastic, paper, putty, primer, coating, and ink industries. Widely used in organic synthesis, metallurgy, glass, and asbestos production. It can also be used as aneutralizing agent for industrial wastewater, an antacid agent for gastric and duodenal ulcer disease, an antidote for acidosis, a sulfur dioxide removing agent for sulfur dioxide in sulfur dioxide-containing waste gas, a dairy feed additive, and an anti-sticking agent for wool felt, etc. It can also be used as a raw material for tooth powder, toothpaste, and other cosmetics.ClassificationItemStandardTest resultsCaCO398.0%-100.5%98.5%HCl insoluble≤0.20%0.15%Free alkaliPass testPass testAlkali metal and magnesium≤1.0%0.85%Ba≤0.030%0.02%As≤0.0003%0.00025%Loss on drying≤2.0%1.45%F≤0.005%0.0035%Pb≤0.0003%0.00023%Hg≤0.0001%<0.0001%Cd≤0.0002%0.0001% White Board Paper Coating Device ConfigurationProcess:Technological process: Odd station shaft type unwind→Single roll feeding device→Air knife surface coating→Hot air circulation drying→Dryer cylinder drying finishing and calendar finishing→Single roll feeding device→Air knife surface coating→Hot air circulation drying→Dryer cylinder drying finishing→Odd station reeling1. Whole machine adopts a unit-frame type structure, machine length can be made according to production requirements.2. Coating type can adopt comma scraper coating, anilox roller coating, micro concave roller coating, extrusion coating, or wire bar coating, according to actual production technology.3. Stepless speed regulation by AC inverter, synchronous control of unwinding,pre-traction, coating, laminating traction, and rewinding.4. Sectional independent homo-thermal drying system of the oven, heating type can adopt electric heating, heat conduction oil heating, and so on, automatic temperature control for each temperature section.5. Automatic coating weight, automatic speed up and down, automatic material breaking inspection, automatic failure warning, automatic separation, and reunion of pneumatic components.6. Unwinding and rewinding adopt automatic rotary double stations, and non-stop material changing. axial thimble type with good nimble reaction and the material being operated is not easy to be crimpled.
