The global retail price of LED bulbs fluctuated in January, according to the LED retail price survey, with the global average price of LED bulbs replacing 40W incandescent bulbs rising about 4 per cent a month, while the price of LED bulbs replacing 60W incandescent bulbs fell 4.3 per cent. Entering a New Year, brand manufacturers will launch new strategies, such as Korean brand factories continue to adopt the parity strategy in the European and American markets.Regions instead of 40 w product price performance, regional price differences, among them, the British because of commodity sales promotion season ended, the partial products sharply raised the price, the rest is a small increase, so the price growth of 14% in January, and Germany, the United States, South Korea and other regions h...

As is known to all, the main raw material of alumina ceramic sheet is alumina, which has certain unique advantages. It is known that alumina ceramic plate is a kind of material with high thermal conductivity and high insulation, with a thermal conductivity of 25W/m.k and a pressure resistance of 13KV. (the thermal conductivity of silicon film is 0.6w /m.k and a pressure resistance of 2KV), it has become the best choice for high-power equipment due to its excellent performance and high cost performance.Where is the application of alumina ceramic sheet? Mingrui ceramics are introduced in detail:...

Q: sintering cracking of pure zirconia ceramics? Grouting method of zirconium oxide, the natural air-dry after 3 days in the high temperature furnace, respectively by 3 ℃ / min and 5 ℃ / min up to 1450 ℃, four hours heat preservation, cooling, are craze, seek a solution.A: this is a paragraph about the forming and sintering technology of zirconia that I read in the book. I hope it will be of some help to you.Powder preparation, due to the high hardness of stable zirconia, usually in the steel ball mill, ball ink after acid washing, and then water clean neutral, drying.It is formed by grouting....

Although zirconia ceramic is a kind of material that is not easy to separate, it will undergo certain deformation under certain external force action, and this deformation is reversible, that is, once the external force on zirconia ceramics is removed, the original shape can be restored.If it is a metal material, it usually goes through two stages of elastic deformation and plastic deformation before fracture under the static tensile load at room temperature. However, zirconia ceramic materials will not be like this, it generally does not appear plastic deformation stage, brittle fracture imme...
