  • 氧化铬绿介绍

          氧化铬绿Cr2O3为六方晶系列或无定形橄榄绿色粉末,有金属光泽。比重5.21,熔点2266±25,沸点4000。不溶于水和酸,可溶于热的碱金属溴酸盐溶液中,稍溶于浓氢氧化钠溶液。对光、大气、高温及腐蚀性气体(SO2、H2S等)极稳定,有很高的遮盖力,具有磁性。有金属光泽,具有磁性,遮盖力强,耐高温,耐日晒,在大气中比较稳定,对一般浓度的酸和碱及气体无影响,具有优良突出的颜料品质和坚牢度。应储存在干燥处,防止受潮,防酸雾,防晒。应与食品隔离储存。氧化铬绿主要用于冶炼金属铬和碳化铬、陶瓷、研磨、抛光、涂料及油墨等工业。

    Cr2O3 for hexagonal crystal or amorphous olive green powder series, with metallic luster. Specific gravity 5.21, melting point 2266 + 25 , boiling point of 4000 . Insoluble in water and acid, soluble in hot alkali metal salt solution, slightly soluble in concentrated sodium hydroxide solution. Light, air, high temperature and corrosive gas (SO2, H2S, etc.) is extremely stable, strong hiding power, has the magnetism. With metallic luster, magnetism, covering power is strong, high temperature resistant, weather resistant, relatively stable in the atmosphere, for the average concentration of acid and alkali and sulfur dioxide gas no effect, good paint quality and fastness. Should be stored in a dry place, prevent be affected with damp be affected with damp, acid mist, prevent bask in. From the food should be stored. Chrome oxide green is mainly used for smelting metal chromium and chromium carbide, ceramic, grinding, polishing, coating and printing ink industries.

    氧化铬绿用途

          主要用途分冶金、颜料、磨料、耐火材料及新发展起来的溶喷涂料5类。

          1.冶金(铝热法制金属铬)用三氧化二铬占产量比例较大。

          2.作为绿色颜料用于涂料、油墨、陶瓷、搪瓷、彩色水泥。氧化铬绿类似叶绿素反射红外线,用于配制类似绿色树叶簇的伪装涂料。

          3.作为研磨剂,用于机械、仪器、仪表、钟表及滚珠轴承的研磨、抛光。直接用作耐火材料,或与氧化镁、氧化铝等制成复合耐火材料。

          4.作为熔喷涂料借助等离子体直接喷涂到金属、陶瓷表面,赋予后者极高的耐磨性、耐蚀性和耐高温性。

          5.三氧化二铬还用作催化剂及其载体,用于制作复合氧化物(包括含三氧化二铬的非绿色颜料)以及作为原料制取铬的碳、氮、硼、硅化物。较新的纳米材料纳米三氧化二铬更具有优异性能和特殊用途。

          冶炼金属铬和碳化铬,搪瓷、陶瓷、玻璃、人造革、耐火材料、建筑材料的着色、有机合成的催化剂、制造耐晒材料和印刷纸币的专用油墨、金属抛光研磨材料、金属表面渗铬、磁性材料等。用于涂料、陶瓷、橡胶、美术颜料、以及伪装涂料等。

    Main use points, metallurgy, pigment, abrasive, fire-proof material and new developed solvent paint 5 classes.

    1. Metallurgical (aluminum hot metal chromium) legal system with chromium trioxide accounted for the largest output.

    2. As a green pigment used in coating, printing ink, ceramics, enamel, color cement. Chrome oxide green chlorophyll reflection infrared, similar to make similar green leaves, clusters of camouflage coatings.

    3. As abrasives, used in machinery, instruments, clocks and ball bearing grinding and polishing. Directly used as refractory materials, or made into composite refractory with magnesium oxide, alumina, etc.

    4. As the melt spray coating using plasma spray directly to the surface of a metal, ceramic, given the high wear resistance, corrosion resistance and high temperature resistance.

    5. Chromium trioxide used as catalyst and its carrier, also used to make composite oxide (including the green paint containing chromium trioxide) and as a raw material for making carbon, nitrogen, boron, chromium silicide. The latest nano materials - nano chromium trioxide has more excellent performance and special purpose.

    Smelting metal chromium and chromium carbide, enamel, ceramic, glass, leather, refractory materials, building materials, color, organic synthesis catalyst, making fast material and special ink printing paper, metal polishing materials, metal surface chromizing, magnetic materials, etc. Used in paints, ceramics, rubber, art paint, and camouflage coatings, etc.
