Natriumaluminat - Safety

Open Data Verified Data

inhalation of aluminum dust mainly damage the lungs, said the aluminum lung, chronic symptoms of weight loss, weakness, easy to fatigue. Production methods listed in this product, the main by-products are water and a small amount of chemical impurities and industrial wastewater. For industrial wastewater, for the different substances contained in the water, for the local environmental protection department to cooperate with the comprehensive treatment; As long as the strict management, no other three wastes discharge. Risk: alkaline corrosion products, the dust has the same nature. Code: GB 12268-90-82008 UN No. 1819, packaging and transportation: packed in woven bags with polyethylene plastic bags, each with a net weight of 50kg. The outside of the package should be clearly marked with "alkaline corrosion" "moisture" text and icon, as well as the provisions of the goods must be written. The port shall be sealed by machine, and the box body shall be baled with slag. Store in a well-ventilated, dry, and corrosive warehouse. Pay attention to water-proof, moisture-proof and fire-proof, and do not store and mix with acid articles. When handling, care should be taken to avoid breakage of the package; Cover the cloth to prevent sun and rain during transportation. Hazards and protection: sodium aluminate for corrosion, the dust has the same properties. The production and use of sodium aluminate work environment to do a good job of dust and dust. Air should be circulated, clean and clean. The equipment and containers containing sodium aluminate should be strictly sealed, and the product should not be scattered and leaked during the process of movement and use, otherwise it should be removed in time. The operator should have labor protection, especially the protection of the respiratory system. After work, take a bath to change clothes, protective equipment should be stored separately, often change. Long-term exposure to sodium aluminate personnel, to do regular lung examination. When there is a fire, it can be controlled by dry sand, dry powder fire extinguisher and asbestos cloth.

Natriumaluminat - Reference Information

EPA chemical substance information	information provided by: ofmpeb.epa.gov (external link)
toxicity	inhalation of aluminum dust mainly damages the lungs, which is called aluminous lung, with emaciation of chronic symptoms and easy fatigue. Attention should be paid to dust and dust.
Use	widely used in industrial water and tap water purification, can reduce the hardness of water and accelerate the settling of suspended solids. The combination with silicate can improve the crystallization of the molecular sieve, and is used as a catalyst and carrier for the conversion of petroleum hydrocarbons, and a raw material for the preparation of amorphous alumina catalyst and stable silica gel solution. It is used as an alkali washing solution inhibitor for glass and ceramic etching, a filler for papermaking industry, a protective agent for reducing oil well water viscosity and steel surface treatment, a soil hardener, and for soap, dye and other industries. mordant. Water softener. Production of zeolites, opalescent glass and soaps, Analytical reagents. It is widely used in the purification of aromatic hydrocarbons in petrochemical industry and the refining of aviation kerosene. It is also used in the refining of lubricating oil, base oil, diesel oil and other oils, and the removal of residual olefins in oil used in water purification agent, paper Filler, Catalyst, etc. is a non-phosphorus builder used as analytical reagent and mordant used as analytical reagent, mordant, can also be used to make zeolite and milky glass
production method	the Bayer process uses bauxite as a raw material, and the mass ratio of alumina to silica in the bauxite is greater than 8, grinding bauxite, ball milling to make the particle size of 85% through 220 mesh, and then mixed with the alkali solution wet grinding, the causticization coefficient reached 1.65±0.02, heated at 150 ℃ for 2~3H, high pressure dissolution, the alumina in the bauxite is transferred to the solution in the form of sodium aluminate, and the impurities silicon oxide, iron oxide and calcium oxide are diluted with water to become red mud. After sedimentation and separation, the crude liquid is filtered and evaporated to dryness to prepare the sodium aluminate finished product. A12O3? 3H2O + 2NaOH → 2NaAIO2+4H2OA12O3? H2O+2NaOH→2NaAIO2+2H2O
