When the alumina is produced by an alkali method, the aluminum ore is treated with a base (NaOH or Na2CO3) to convert the alumina in the ore into a sodium aluminate solution. Impurities such as iron and titanium in the ore and most of the silicon become insoluble compounds. The insoluble residue (red mud) is separated from the solution, washed, discarded or subjected to comprehensive treatment to recover useful components therein. The New Year's inspection of Zhisheng Weihua high-temperature anti-corrosion coating experts pointed out that the pure sodium aluminate solution can be separated into aluminum hydroxide, after separation, washing and calcination, the alumina product is obtained, and the alumina is electrolyzed by Er-Aluminium Get aluminum.

 

Application Analysis of Alkali Aluminum Refining Coatings

 

Improve the technical research and development of smelting anti-corrosion coatings and improve the anti-corrosion performance of smelting anti-corrosion coatings. The purpose of smelting anti-corrosion coatings for anti-corrosion coatings is to be able to withstand long-term industrial production and safety and corrosion resistance technical requirements, to protect the substrate from corrosion and oxidation, and to use coatings for a long time. Zhisheng Weihua anti-corrosion coating technology engineer pointed out that industrial anti-corrosion coatings should have excellent corrosion resistance and heat resistance, meet the needs of industrial production and safety technology, meet the mechanical strength and flexibility required by industrial equipment, and have the long-term need for acid and alkali resistance. . The demand for industrial anti-corrosion coatings continues to rise, and anti-corrosion coatings meet the industry's basic requirements.

 

Good industrial smelting anti-corrosion coatings are mainly used in the chemical and petroleum industries, railways, highway bridges, metallurgical industry, power and energy industry, machinery and textile industry, aerospace, marine water, automotive machinery, shipbuilding and container industries. In the industrial chemical, petroleum, food, light industry and other industries, most of the equipment and pipelines are corroded due to the presence of corrosive media. The concentration and temperature of the corrosive medium change at any time, so the corrosion is very strict. Weihua's various ZS series anti-corrosion coatings are suitable for anti-corrosion requirements on various industrial equipments. Covering or lining with various anti-corrosion materials can completely isolate metal equipment from corrosive media, prevent corrosion and abrasion of equipment, and improve equipment. Corrosion resistance, wear resistance, safety and long life.

 

China's Zhisheng anti-corrosion coating research and development is developing rapidly. Based on the traditional commonly used Zhisheng anti-corrosion coatings, many new anti-corrosion coatings with excellent performance have been developed and applied in practical engineering. Shengweihua's new anti-corrosion coatings have excellent performance, and some varieties of performance indicators have caught up with or surpassed the same foreign coatings. Domestic large-scale anti-corrosion coatings company, Beijing Zhisheng Weihua Chemical Co., Ltd., in the research and development of inorganic anti-corrosion coatings, the company's more than ten years of research and development of inorganic polymerization technology has been at the forefront of the world, Beijing Zhisheng Weihua Chemical Co., Ltd. 2300 °C high temperature corrosion ZS-811 high temperature anticorrosive coating, direct flame retardant resistance; ZS-822 composite ceramic high temperature anticorrosive coating, temperature resistance up to 1400 ° C, high temperature oxidation resistance, high purity and no volatile, it can withstand strong solvents and mixing Long-term immersion of solvent; ZS-833 flexible high temperature ceramic anticorrosive coating, with good ceramic properties and good flexibility, suitable for anti-corrosion under special working conditions; ZS-1033 anti-corrosion resistant to hydrofluoric acid ZS-1041 flue gas anticorrosive coating which can resist high temperature flue gas and flue gas condensate strong corrosive friction; ZS-1042 desulfurization special anticorrosive coating, strong corrosion resistance, wear resistance and thermal shock resistance; can withstand seawater and seawater wet Gas corrosion ZS-711 inorganic anticorrosive coating; can increase heat exchange anticorrosive coating acid and anticorrosive coating ZS-722 thermal anticorrosive coating; resist strong friction impact corrosion ZS-10 31 wear-resistant anti-corrosion coating; ZS-821 ceramic anti-corrosion coating which can resist ether, fluorine and oil corrosion corrosion; ZS-1034 resistant to most acid-base corrosion, salt, solvent and intermediate medium corrosion Acid-base anti-corrosion coating; resistant to strong oxidation and corrosion of nitric acid, concentrated sulfuric acid, concentrated hydrochloric acid ZS-1032 strong anti-corrosion coating; ZS-1023 resistant to strong oxidation and anti-corrosion coating resistant to oxidation at 3000 °C, above Zhisheng anti-corrosion coating Different anti-corrosion coatings are used under different acid corrosion conditions, which can be used to protect the surface from contact with strong chemical corrosion. Zhisheng Weihua has successfully developed a variety of Zhisheng anti-corrosion coatings, with high technology content, wide application prospects and promising market prospects. Zhisheng Weihua is also an expert in Zhisheng anti-corrosion industry. It can be used under harsh conditions and has a long-lasting anti-corrosion life. Zhisheng anti-corrosion coatings can be used in chemical atmosphere and marine environment for 10 or more years, even in acid, alkali, salt and solvent media. It can also be used for more than 5 years under certain temperature conditions.
