sulphate-resistant cement

Existing commercial deoxidizer can' t meet the industrial requirements in performances when it is used in the processes for making ammonia or city gas from coal or residual oil as raw materials, so a new kind of Co - Mo deoxidizer with good sulphur resistance is developed which contains a novel promoting agent and is made by modified kneading method.
