Japan: New Type B Fluorescent Lamp Japan Mitsubishi recently introduced a new type B fluorescent lamp.
This lamp consists of four fluorescent tubes that are shaped like a B character. Its high luminous efficiency, this lamp of 27 watts has the brightness equivalent to 100 watts incandescent lamp, and the power consumption and the calorific value are only 1/3 of it, and its service life is 6 times.
Germany: Moldable wood-plastic materials The Langhof Chemical Technology Institute in Germany recently developed a plastic-wood material that can be molded like plastic.
The existing ordinary wood is mainly composed of cellulose and lignin. The cellulose gives the wood a certain strength, and the combination of cellulose and lignin makes the wood tough. According to this principle, the Institute mixes natural cellulose and paper mills as waste lignin to form granules, which are then placed in the mold cavity of an ordinary injection molding machine at high temperatures and pressures. Under the conditions, this plastic wood material composed of cellulose and lignin will be tightly combined and processed into the desired shape to make a new molded wood product.
When this moldable plastic wood material emerged, it was favored by furniture dealers, packaging material suppliers and decoration material suppliers. Sweden's IKEA furniture company believes that molded wood products have been on the market for more than 10 years, but so far the molded wood products are composed of wood fibers and adhesive resins, and their mechanical properties are similar to those of the composition resins. Can only be used to make hollow doors and automotive interior parts. The new type of plastic wood material is different, it can almost reach the performance of natural wood, completely known as authentic wood, with its molded wood products free saw no planing, and natural wood products made of nothing In both cases, even the degree of shrinkage or swelling due to temperature changes is no different from natural wood.
This moldable plastic wood material has a wide range of uses and can be used not only to mold wood products such as floors, doors and windows, and furniture, but also to manufacture cases, computer and television housings, car doors and fenders, etc. And, more importantly, products that can be used to make a combination of wood and metal parts. In the past, since plastics and metals swelled more than wood, cracking of wooden parts was prone to occur. Nowadays, parts made of wood-plastic materials can avoid this problem.
US: Catalysts for hydrogen production from water For a long time, humans have been hoping to use solar energy to decompose water to make hydrogen. Because hydrogen only produces water when it burns, it does not produce any pollutants and is one of the ideal energy sources in the future. Therefore, researchers have been looking for the ideal catalyst to increase the efficiency of photodecomposition of water to hydrogen production. Although many effective catalysts have been invented, none of them are practical, inexpensive, and stable catalysts. Recently, Kahn and his students at the University of Duquesneig, Pennsylvania, USA, added carbon to the electrolyzed water catalyst titanium dioxide to enhance their ability to absorb visible light, which increased the catalyst's ability to photodegrade water to hydrogen production by up to 8 times. 8.5%. Although this efficiency is still lower than the reference point of the US Department of Energy's 10% conversion rate for commercially viable catalysts, Kahn’s research team is expected to overcome this difficulty and increase its efficiency to more than 10%.
Japan: High-strength Composite Ceramics Japan Udo Industries recently developed a high-strength composite ceramic material that can be used at high temperatures above 1600 degrees Celsius.
This material is a mixture of aluminum oxide and yttrium oxide, placed in a special container and melted, and then precisely controlled the temperature so that it is solidified. In this process, two raw materials are combined to form a new structural material and its melting point can reach 1800 degrees Celsius. This new material was placed in an aerobic environment at 1700 degrees Celsius and placed under a temperature of 1000 degrees Celsius for an oxygen tolerance test. As a result, its weight, structure, and strength remained unchanged.
This material can be used to manufacture turbine blades for jet engines or power generation. After the heat resistance of the blades is improved, it is possible to manufacture high-efficiency generators and main components of the engine that do not require cooling.
Germany: BK Infiltrating Glaze with Bright Colors For the quality problems of poor blemishes with special colors, such as black, blue and pink porcelain enamel bricks, Beckmann Gilny Chemical Co., Ltd. of Germany recently introduced BK enamel glaze and perfect technical services.
The BK penetrating glaze produced by this company is a precious metal liquid with strong penetrating power and can penetrate into the ceramic body more than 2 mm. With only a few grams of permeating glaze, each brick can achieve the perfect effect of osmosis, which has been adopted by ceramic enterprises in Italy and Spain and Other countries. It has become an infiltration glaze for high-grade imitation stone products.
Baker Gellini has more than 170 years of history and is a world famous chemical company. It has many wholly-owned and joint venture companies all over the world. Its main products are ceramic tile, paint, fur, toothpaste, detergent, food additives and chemical products. .
