河南省三门峡市京峡化工厂引进开发的羧甲基淀粉钠(缩写为CMS-Na),是一种优良的增粘剂、降失水剂、悬浮剂、稳定剂和品种改良剂。与钠羧甲基纤维素(即CMC-Na)相比,CMS-Na具有极易溶解(一般不需热水预水化)、分散性能好、降失性显著、提粘快、抗侵蚀、稳定性好等特点,此外,还具有较好的乳化性,可长期保存不变质。可用于地质钻探、石油勘探、纺织业、造纸业、建筑及日用化工等工业领域。我队工作的灵宝县大湖金矿区,地层复杂,构造裂隙十分发育,硬、脆、碎、软泥巴岩矿层交互,钻进中掉块、垮孔、糊钻、缩径、堵心、涌漏等情况 Sodium Carboxymethyl Starch Sodium (abbreviated as CMS-Na) introduced and developed by Jingxia Chemical Plant of Sanmenxia City of Henan Province is an excellent thickener, fluid loss reducing agent, suspending agent, stabilizer and variety improver. Compared with sodium carboxymethylcellulose (CMC-Na), CMS-Na is very soluble (generally without hot water pre-hydration), good dispersibility, significant drop loss, fast curing, anti-erosion, Good stability and other characteristics, in addition, also has good emulsifying properties, long-term preservation without deterioration. Can be used for geological drilling, petroleum exploration, textile industry, paper industry, construction and daily chemical industry. The team work in the Great Lakes gold mine Lingbao County, stratigraphic complexity, the development of structural fractures are very developed, hard, brittle, broken, soft mud Bam rock interaction, drilling in the block, down hole, paste drilling, Diameter reduction, Chung leaks and so on
