GB/T 11213.5-2006
ActiveSodium hydroxide for chemical fiber use - Determination of sulphate content
化纤用氢氧化钠 硫酸盐含量的测定
Application Summary AI generated
This standard specifies the method for determining sulphate content in sodium hydroxide used specifically in the production of chemical fibers, such as viscose rayon. It is applied in quality control laboratories within the chemical fiber industry to ensure that the sodium hydroxide raw material meets purity requirements, as excessive sulphate can negatively affect fiber spinning processes and final product quality. The standard provides a testing protocol for manufacturers and users to verify compliance with technical specifications.
