Alumina can also be used as analytical reagents, dehydration of organic solvents, adsorption agents, organic response catalysts, abrasives, polishing agents, raw materials for smelting aluminum, and refractory materials. In addition, alumina can also be used as hyperfluoro -drinking fluoride, used as an oxygen -making industry, textile industry, and gas drying in the electronics industry. The alumina contains element aluminum and oxygen. If the aluminum aluminum raw material is chemically treated, the product made from the oxides such as silicon, iron, titanium, etc. is a very high purity alumina raw material. The AL2O3 content is generally above 99%. M ore phase consists of 40%to 76%γ-Al2O3 and 24%to 60%α-Al2O3. γ-Al2O3 can be transformed into α-Al2O3 at 950-1200 ℃, and significant volume contraction occurs at the same time.
Aluminum hydroxide is the maximum dosage and the most widely used inorganic flame retardant additive. Aluminum hydroxide can not only be flame retardant, but also prevent smoking, no drops, and no toxic gases. Therefore, it has obtained a widespread application, and the amount of usage is also increasing year by year. Scope of use: thermosetry plastic, thermoplastic plastic, synthetic rubber, coatings and building materials industries. Aluminum hydroxide aluminum hydroxide is divided into two types: industrial and pharmaceutical. I. Industrial Grade Introduction: Molecular formula: AL (OH) 3 or Al2O3 • 3H2O molecular weight: 78 1.

Scope of use: thermosetry plastic, thermoplastic plastic, synthetic rubber, coatings and building materials industries. 3. Packaging, transportation, storage packaging: Internal plastic and outer coating film bag, each bag is 25kg or 40kg. Transportation: This product is non -dangerous goods. During the transportation, it prevents moisture, rain and packaging damage. Storage: Store in a dry and ventilated warehouse. 2. Introduction to Medicine -grade aluminum hydroxide: Aluminum hydroxide dry gel English name Aluminium Hydroxide Dried Gel Aluminum Aluminum Gel Molecular AL (OH) 3 molecular weight is used for gastrointestinal suppression of gastric acid, commonly used as compound prescription Preparations such as Udrus and aluminum capsules and aluminum hydroxide pieces can also be used for medicinal auxiliary materials. Properties: white powder, odorless and tasteless. Insperfolid in water and ethanol, soluble in thin inorganic acids such as hydrochloric acid. Main control indicators: acid power: not less than 230ml/g, content: not less than 48.0 % according to aluminum dioxide (according to aluminum hydroxide, not less than 76.5 %). Product Quality Execution Standard: Chinese Pharmacopoeia CP2005 version/American Pharmacopoeia USP28. Double -layer polyethylene plastic bags are used in the packaging and transportation inner bag, and the external single -layer polyethylene plastic woven bags or paper plastic composite bags, cardboard barrel packaging; each bag of net weight is 20kg. Dry warehouses should be stored. The packaging should be completely sealed to prevent moisture. Do not store mixing with acid products. Drinking volume: 2.8 cubic meters/ton. The fine amount of fine powder for this product (about 0.5g of hydroxide), 10ml of dilute hydrochloric acid, after heating and dissolving, filtering, and the identification reaction of aluminum salt (Appendix Ⅲ). Pharmacological toxicology has no direct effect on the secretion of gastric acid, and the chemical reactions of gastric acid rising or buffer in the gastric acid can cause an increase in the pH value in the gastric, which can relieve the symptoms of excessive gastric acid. Among them, the ability to harmonize is lower than that of magnesium containing agents and calcium carbonate, while higher than carbonate and sodium carbonate and carbonate. In addition, aluminum ions are discharged from the intestine with the insoluble aluminum phosphate from the intestine. A very small amount of pharmacokinetics is transformed into soluble aluminum chloride in the stomach and was absorbed and excreted from urine. Most aluminum ions are combined into the insoluble aluminum salt in the intestine, such as phosphate, carbonate And fatty acid salt, excreted from feces. The effect of this product is slow, and the length of time in the gastrointestinal effect is related to the speed of gastric emptying. The effect of fasting can last for 20 to 30 minutes, and the time limit for taking the medicine 1 to 2 hours after a meal may be extended to 3 hours. Indications can alleviate symptoms such as excessive gastric acid and merged. It is suitable for the treatment of gastric and duodenal ulcer, and the treatment of reflux esophagitis; Symptoms (hand and foot convulsions). Patients with uremia can reduce the absorption of phosphate and reduce acidmia.
