摘　　要：主要研究了腐植酸在电瓷配方中的应用以及它对电瓷工艺流程、电瓷本身性能的影响。经过多轮小样实验，确定在坯料配方中添加比例0．2%-0．5％的腐植酸，实验表明，腐植酸可提高坯体干燥强度30％-50％，并可以同时提高坯体的可塑性，但对电瓷其他性能无负面影响。The use of humic acid in porcelain formula, and the effect of it on the porcelain insu- lator technological process, and performance of porcelain itself are researched. As a result of repeated experiments of galley proof, the humie acid is decided to toad in blank formula by proportion of 0.2- 0.5 percent. The test result shows that the humic acid can improve the intensity of dry-blank by 30%- 50%, and can improve the plasticity of clay at the same time, however it has no negative effect to other performance of the porcelain insulator.
