Product Description Changshu Hongyu Calcification Co., LTD., relying on colleges and universities,adopts new technology to specialize in the production of industrial,chemical, petroleum additives with calcium hydroxide, calcium oxide and other lime products.The product is mainly used in the production of petroleum additives, lubricants, petrochemical products and environmental protection, sewage treatment, food desiccant and other industries. Scientific testing methods, strict management, to ensure the quality of products.After the use of this product by some large petrochemical enterprises in China, the finished products produced have low cost, high purity and good efficiency, and are very popular in the market.The company has three processing lines, more than 100 tons of lime products per day. Production of calcium hydroxide, calcium oxide and other products, the quality of the enterprise's internal control standardsAbout calcium hydoxide,we can supply≥90% grade calcium Hydroxide≥95% grade calcium hydroxide98%-99.5% grade calcium hydrooxide (We are the first factory in Chinese Mainland that can produce this product)COA,MSDS,TDS,SGS files for each grade are available.Industrial calcium hydroxide is a multifunctional chemical that has been widely used in many industrial fields. The following are its main uses:Environmental protection field: As an environmental protection neutralizer, it is used in acidic wastewater, sewage treatment, sludge treatment, boiler flue gas desulfurization and other processes. In addition, it can also be used to precipitate suspended solids and remove phosphates from water, thereby improving water quality.Chemical raw materials: as important additives, fillers and auxiliaries in coating, rubber, paper and other industries. For example, in the coating industry, calcium hydroxide can be used as a filler, can also replace titanium dioxide and pigments, and according to its chemical reaction properties, can also be used to precipitate barium sulfate. In the rubber industry, calcium hydroxide can be used as a filler for rubber products, which can improve the processing properties of rubber and also improve the mechanical properties of products. In the paper industry, calcium hydroxide is an important inorganic filler, which can effectively improve the permeation and diffusion capacity of paper products.Metallurgical industry: In the production process of aluminum, calcium hydroxide is used as a pickling agent for bauxite to remove impurities from it. In metal processing and smelting, it can also be used for desulfurization and decarbonization reactions to purify metal materials.Building materials: In the production of concrete, calcium hydroxide as an alkaline activator can promote the solidification and curing process of concrete, and can also be used to adjust the acid-base balance of concrete to improve the durability and corrosion resistance of concrete. In addition, it can also be used to make limestone, gypsum and other building materials to neutralize acidic substances in materials and improve strength and durability.Glass manufacturing: In the glass manufacturing process, calcium hydroxide is used as a stabilizer to help control the PH and hardness of the glass.Chemical reactants: Calcium hydroxide can be used as a catalyst or reactant in many chemical reactions, such as alkaline neutralization and precipitation reactions in chemical synthesis. It can also be used as a substitute for and in catalyst preparation, acid neutralization reactions and organic synthesis processes.calcium hydroxide product introduction: 1. Nicknames of calcium hydroxide: slaked lime, hydrated lime 2. The main component of calcium hydroxide :Ca(OH)2, molecular weight 74.8 3. Production method of calcium hydroxide: The finished product is obtained by digesting calcium oxide with water and drying, sifting and windpicking. 4. Physical and chemical properties of calcium hydroxide: strongly alkaline. Placed in the air, it gradually absorbs carbon dioxide and becomes calcium carbonate. Slightly soluble in water, soluble in acid. With a density of 22.4g/cm3, its clarified aqueous solution is a colorless odorless alkaline transparent liquid with a PH value of 12.4Basic uses of calcium hydroxide products:1. Calcium hydroxide is used as an environmentally friendly neutralizer for acid wastewater, sewage treatment, boiler flue gas desulfurization. 2. Calcium hydroxide can also be used as chemical raw materials, additives, additives, fillers for leather, metallurgy, coatings, petroleum lubricants, paper and so on. 3. Other uses of calcium hydroxide: Calcium hydroxide is used as stone cutting aid, soil stabilizer, concrete tempering agent, chemical reagent, gypsum board caulking coagulant, construction adhesive ingredients, hard water softener, plastic fiber and so on. A, calcium hydroxide environmental treatment with Ca(OH)2 screening rate of 125 mesh ≥90% B, calcium hydroxide as a strong alkaline flocculant to neutralize acidic wastewater to make acidic wastewater neutral. C, calcium hydroxide absorbs SO 2 in boiler flue gas, so that the sulfur content of emission flue gas meets environmental protection standards. D, calcium hydroxide wastewater treatment effect comparison, is the conventional alkaline coagulant wastewater treatment is recognized as the world's most alkaline neutralizer. calcium hydroxide product use method: 1. When calcium hydroxide is added by dry method, the equipment is simple, but the reaction is slow and the utilization rate is not high;When wet calcium hydroxide is added, it is generally prepared into a calcium hydroxide lime emulsion with a mass fraction of 5%-10%, which has a fast reaction and is stirred for 5-20min. 2. Handling of abnormal problems: When the influent PH value changes greatly, the dosage should be increased or decreased in time;Calcium hydroxide emulsion should be diluted after adding, easy to mix reaction;The sludge produced in the process of neutralization should be separated and removed in time. Calcium hydroxide product packaging and storage: 1. calcium hydroxide transport precautions: the packaging should be complete when shipping, loading should be secure. Calcium hydroxide should not be transported in rainy days. 2. calcium hydroxide storage precautions: store in a cool, ventilated warehouse. The humidity in the warehouse * is not more than 85%. The packaging must be completely sealed to prevent calcium hydroxide moisture absorption. 3. calcium hydroxide outer packaging are 1000 kg/ton bag and 25 kg/bag woven bag. 4. according to the different actual needs of customers, calcium hydroxide can also be transported by tank truck.
