Development Trend of Cryolite Industry and Market Application Prospects of Cryolite Industry
With the development of technology, the domestic and international cryolite market is still hot, and the country attaches great importance to environmental protection. Overall, international environmental issues pose a risk of rising costs for the electrolytic aluminum industry. With the development of technology, the domestic and international cryolite market remains hot. In recent years, the rapid expansion of China's electrolytic aluminum industry has further stimulated the development of the cryolite industry.
α- Alumina and γ What are the differences between alumina?
one α- Aluminum oxide, also known as nano aluminum oxide, exhibits a white fluffy powder state with a crystal form of xz-L14 α Type. The particle size is 20nm; Specific surface area ≥ 50m/g. Uniform particle size distribution, high purity and high dispersion. It has low specific surface area and high temperature resistant inertia, but it does not belong to Activated alumina and has almost no catalytic activity.
Special alumina: ceramics, abrasives, catalysts Market demand continues to increase without decrease
Except for metallurgical grade aluminum oxide, various types of aluminum oxide, aluminum hydroxide, and aluminum containing compounds are referred to as chemical aluminum oxide, which is collectively referred to as non metallurgical grade aluminum oxide internationally. Among them, those that undergo special processing and have certain differences in performance compared to metallurgical grade aluminum oxide are referred to as special aluminum oxide.
Production process of calcined alumina micropowder
The production process of calcined alumina micropowder uses industrial aluminum hydroxide or industrial alumina as raw materials, and is calcined at appropriate temperature to form a stable crystal form α- Type alumina products; To calcine α- Alumina micropowder made from type A alumina through ball milling. High temperature calcined alumina powder products have a high melting point, excellent mechanical strength, hardness, high resistivity, and thermal conductivity. It can be widely used in industries such as electronic equipment, structural ceramics, refractory materials, wear-resistant materials, polishing materials, etc.
Introduction and Application of Aluminum Oxide
Alumina is a widely used inorganic compound, and its molecular formula is Al2O3. It has many excellent physical and chemical properties, making it widely used in industries, healthcare, electronics, construction, and other fields.
Teach you to correctly identify inferior aluminum profiles!
The titanium gold plating process on aluminum profiles belongs to the coating technology. It adds pre plating and electroplating process steps to the conventional titanium plating process. The aluminum profile process involves chemically treating the activated plated parts in an aqueous solution of salt and hydrochloric acid; The plating solution components of the electroplating process include nickel sulfate, nickel chloride, boric acid, sodium dodecyl sulfate, saccharin, and brightener. This process has the advantages of simplicity, practicality, and good results. The film hardness of the titanium aluminum profile produced by this process is HV ≈ 1500, and under the same conditions, it is 150 times more wear-resistant than 22 K gold plating. It can be processed into various forms of gold, color, black, and other bright series of aluminum profile products.
One public announcement of the environmental impact assessment for the annual production of 40000 tons of high-performance anhydrous aluminum fluoride and 20000 tons of electronic grade hydrofluoric acid by Fude Technology Co., Ltd
According to the relevant provisions of the Environmental Protection Law of the People's Republic of China and the Environmental Impact Assessment Law of the People's Republic of China, our company has entrusted a third-party evaluation agency to carry out an environmental impact assessment project for the proposed "Annual Production of 40000 tons of high-performance anhydrous aluminum fluoride and 20000 tons of electronic grade hydrofluoric acid project", and in accordance with the relevant provisions of the "Public Participation Measures for Environmental Impact Assessment" (Order No. 4 of the Ministry of Ecology and Environment), The relevant information on the environmental impact assessment of this project will be made
Analysis of China's aluminum fluoride production capacity in April
Research shows that in April 2021, 17 domestic dry process aluminum fluoride production enterprises completed a production capacity of 1.018 million tons (in production), and as of April 25, the operating capacity for the month was 186000 tons. It is expected that the average operating rate at the end of the month (the fourth week of April) will be 11.3%, a decrease of 21% compared to the beginning of the month (the first week of April), and the average operating rate for the month is expected to be 18.3%. In addition, seven wet process aluminum fluoride production enterprises have built a production capacity of 135000 tons and an operating capacity of 90000 tons, with an operating rate of 66.7%.
Introduction to Wall Thickness Deviation of Aluminum Profile
The wall thickness of aluminum alloy profiles is one of the main indicators of profiles, and both door and window profiles and curtain wall profiles have a nominal wall thickness. 55 series doors and windows, with a nominal wall thickness of 1.4mm. There is a deviation between the actual measured wall thickness of the profile and the nominal wall thickness, and the measured wall thickness often does not exactly match the nominal wall thickness value, such as 1.4mm measuring 1.42mm. So why is there a bias? Below is an introduction and explanation.
Things about alumina and mineralizers
α- Aluminum oxide, also known as calcined aluminum oxide, has the characteristics of high melting point, high hardness, strong insulation performance, good wear resistance, and stable chemical properties. It is widely used in many fields such as refractory materials, insulation equipment, integrated circuit substrates, abrasive tools, ceramic materials, and so on. In order to adapt to different industries α- Due to the special needs of alumina, people form a variety of high value-added products by controlling its primary crystal shape, particle size distribution and impurity content.
