环保设备与粉体工程应用研究中心抗腐蚀铁粉加重剂Anti-corrosion iron powder heavyweight additivesDate: 22/03/2010 Introduction本品为优质铁精粉，并采用西安理工大学粉体中心的超细、包膜处理技术的抗腐蚀铁粉加重剂，粒度可达200600目。具有良好的抗蚀、抗盐、耐磨等特性，可用于高密度海洋钻井液、并能对加重剂循环使用。高密度固井水泥浆，能够有效提高水泥的抗盐防蚀能力，延长油井寿命。The product is high-quality iron concentrate, adding anti-corrosion iron powder heavyweight additives with ultrafine crushing, coating technology researched by Powder Center of Xian University of Technology. Particle size is up to 200-600 mesh with good corrosion resistance, salt resistance, wear resistance and other characters. It can be used in high density offshore drilling fluid, and the heavyweight additives can be recycled. High-density cementing slurry can effectively improve anti-corrosion and anti-salt ability and extend oilwell life.CharactersPhysical state dark grey powderDensity5.06.0g/cm3 5.05.8g/cm35.05.5g/cm3Fineness200300mesh300400mesh400600meshMain componentsFe76% 72% 72% SiO23.0%3.0%3.8%Mn5.0%5.0%6.0%C1.0%1.0%1.0%BM10%10%10%Size distribution200mesh with 10% sieving residue300mesh with 10% sieving residue400 mesh with 10% sieving residue Anti-salt propertyWithout corrosion soaked in saline with 710% NaCl for three days.
