提高木质素磺酸镁干粉抗吸潮性的研究

Study on Enhancing Moisture-Proof Ability of Magnesium Lignosulfonate Powder

为了综合利用红液，生产廉价而有效的表面活性剂──木质素磺酸镁干粉（木镁于粉）时，由于木镁干粉吸潮性强，给生产和应用带来不便。介绍了提高木镁抗吸潮性能的生产方法，使其达到木质素磺酸钙的抗潮性能，而保持其原有的表面活性不变。

There are some problems during producing magnesium lignosulfonate powder a kind of cheap and efficien surfactant from red liquor. The powder is easy most and brings difficulties in production and application. A method of producing the same moisture proof ability as the calcium lignosulfonate and remaining its surfactivity is introduced.
