Steel room temperature blackening agent at room temperature blackening agent cast iron, steel blackening agent, iron black, manufacturers ..

Fast black steel at room temperature, is currently being vigorously promote energy-saving, high efficiency, advanced manufacturing technology for machining steel parts, powder metallurgy and casting, forging oxide black (the Koran). Its characteristics are effectively overcome the traditional black (the Koran) the existence of high-energy processes, inefficient and polluting the environment of the three problems. The product in September 1991 by the National Science and Technology Achievements Award of Excellence State Science and Technology Trade Fair held in Zhengzhou; and in November 1993 passed technical appraisal Changsha City Science and Technology Commission, chaired. In the same year a column provincial scientific and technological achievements. 1995 Office of the State Science and Technology Commission issued the results of [(95) NSC to do word No. 135] to promote the country and the promotion will be held in Changsha. 1995 by the Hunan International New Technology and New Product Exposition. GB / T15519-2002 chemical conversion coatings - Black oxide coating on iron and steel national standard-setting unit. First, the characteristics and level 1, normal temperature range, does not require complex heating equipment, energy-saving effect is remarkable; 2, improve work efficiency, production volume and flexible, ready to meet production requirements; 3, corrosion resistance than the old technology can enhance the effect of black pieces; 4, does not produce harmful gases, protect the environment; 5, less investment and quick, simple process, easy to operate, than the old process to reduce costs by 20% or so. Experts believe that the successful development of HH-902 steel room temperature blackening agent is a new breakthrough in China's steel black technology, its reliability, advanced performance in: 1, superior performance, strong adaptability to a variety of steel can handle silicon steel, cast iron and include 08F cold-rolled steel, including low-carbon steel, to solve a problem currently prevalent in low temperature oxidation technology; 2, good storage performance, more than one-component solution storage period of two years; 3 appearance and corrosion resistance in line with GB / T15519-2002 chemical conversion coating - steel black oxide film (National Standards), WJ535-82 (weapons industry standard) and DIN50938 (German standard). 4, black film quality inspection can be carried out immediately after the completion of the production process, without having to wait for a long time aftereffect; 5, good black film adhesion, abrasion resistance performance than similar domestic products; 6, improve the matching process, available complementary products and supporting technology, production line design.
