用途与场景

登记用途：Uses: Used in medications、animal feeds、insulation、wallboard、electrical heating rods、crucibles、fire bricks、petroleum additives、boiler scale control agents、and food additives、[HSDB]、Farming (Feed Additives) [Category: Industry]、Both oil base and water base fracturing fluids are being used in the fracturing industry. Water base、which includes alcohol-water mixtures and low strength acids、make up the majority of treating fluids. The common chemicals added to these fluids are polymers for viscosity development、crosslinkers for viscosity enhancement、pH control chemicals、gel breakers for polymer degradation following the treatment、clay stabilizers、alcohol、bactericides、fluid loss additives and friction reducer.、Hydraulic fracturing、Hydraulic fracturing uses a specially blended liquid which is pumped into a well under extreme pressure causing cracks in rock formations underground. These cracks in the rock then allow oil and natural gas to flow、increasing resource production. ... Chemical Name: Magnesium oxide、Chemical Purpose: Allows a delayed break down of the gel、Product Function: Breaker.、For magnesium oxide (USEPA、OPP Pesticide Code: 009235) there are 0 labels match.、SRP: Not registered for current use in the U.S.、but approved pesticide uses may change periodically and so federal、state and local authorities must be consulted for currently approved uses.、CHEM INT MEDICINALS AND OTHER CHEMS、COMPONENT OF ANIMAL FEEDS、INSULATION、AND WALLBOARD、COMPONENT OF PETROLEUM ADDITIVES、OXYCHLORIDE AND OXYSULFATE CEMENT、AGENT IN PULP AND PAPER MFR、FOOD CHEM、RUBBER ACCELERATOR、COMPONENT OF ELECTRICAL HEATING RODS、MISC APPLICATIONS、For more Uses (Complete) data for MAGNESIUM OXIDE (12 total)、please visit the HSDB record page.、Use Classification: EPA Safer Chemical Functional Use Classes -> Processing Aids and Additives、Safer Chemical Classes -> Green circle - The chemical has been verified to be of low concern、Food Additives -> ANTICAKING_AGENT -> JECFA Functional Classes、Cosmetics -> Buffering、Absorbent、Opacifying、Industry Uses: Flux agent、Stabilizing agent、Catalyst、Corrosion inhibitor、Thickening agent、Filler、Not Known or Reasonably Ascertainable、Soil amendments (fertilizers)、Hardener、Pigment、Processing aids、specific to petroleum production、Intermediate、Adsorbent、Polymerization promoter、Flavoring and nutrient、Insulators、Other、Processing aids not otherwise specified、Plating agent、Chemical reaction regulator、Fuel agents、pH regulating agent、Consumer Uses: Processing aids not otherwise specified、Deodorizer、Binder、Surface modifier、Flux agent、Household Products: Information on 37 consumer products that contain Magnesium oxide in the following categories is provided:、• Auto Products、• Home Maintenance、• Inside the Home、• Landscaping、Yard、• Personal Care、• Pesticides、Methods of Manufacturing: ...、Dolomitic、limestone is calcined at a high temperature under controlled conditions to produce calcined dolomite or dolime which upon reaction with magnesium chloride-rich brine produces magnesium hydroxide and calcium chloride. The insoluble magnesium hydroxide is then separated from the liquid calcium chloride carrier and calcined under controlled conditions. The various grades of magnesia range from very reactive light-burned to nonreactive dead-burned.、... Mining、crushing、sizing、and subsequent calcination of natural magnesite. The chemical purity of the magnesia produced is dependent on the mineralogical composition of the natural magnesite.、A concentrated magnesium chloride brine processed from the Dead Sea is sprayed into a reactor at about 1700 °C. The brine is thermally decomposed into magnesium oxide and hydrochloric acid. To further process the magnesia、the product is slaked to form magnesium hydroxide which is then washed、filtered、and calcined under controlled conditions to produce a variety of magnesium oxide reactivity grades.、The seawater process ... involves decarbonating limestone or dolomite to the point where all CO2 is removed without converting the resulting magnesia to a chemically inactive form. Reaction of filtered seawater、treated to remove bicarbonate and、or sulfate、and dolime is followed by seeding with magnesium hydroxide to promote crystal growth. Upon formation of magnesium hydroxide、flocculants are added and the magnesium hydroxide precipitate is allowed to settle while the spent seawater is disposed to the sea. The precipitate is washed、and dried to obtain magnesium hydroxide which is calcined to produce light-burned、hard-burned、or dead-burned magnesium oxide.、Light or heavy magnesium carbonate is exposed to red heat、whereupon CO2 and H2O are expelled、and light or heavy magnesium oxide is left. The density of the oxide also is influenced by the calcining temperature、high temperature yielding more compact forms.、Impurities: TRACE IMPURITIES: NaCl、KCl、NaF、Formulations、Preparations: The principal commercial forms of magnesia are dead-burned magnesia (periclase)、caustic-calcined (light-burned magnesia)、hard-burned magnesia、and calcined dolomite.、Table: Magnesium Oxide Preparations [Table#3440]、Consumption Patterns: 20% IS USED IN CHEMICAL MANUFACTURING、18% IN ANIMAL FEED AND FERTILIZER、16% FOR MEDICINALS、INSULATION AND WALLBOARD、FLUX、AND PETROLEUM ADDITIVES、14% FOR OXYCHLORIDE AND OXYSULFATE CEMENT、12% FOR PULP AND PAPER MANUFACTURING、6% AS A RUBBER ACCELERATOR、4% USED IN FOODS、2% IN ELECTRICAL HEATING RODS、8% FOR UNSPECIFIED USES (1972)、CHEMICAL GRADE ONLY-DERIVATIVE: ANIMAL FEEDS AND FERTILIZERS、35%、MEDICINALS、SUGAR & WINE MAKING、4%、CONSTRUCTION MATERIALS、5%。
