本文在对美国最新产品DESCO与国内现有产品SMK进行系统分析对比的基础上,提出将栲胶与高价金属离子络合后,再进行磺化,以提高SMK抗温及稀释效能。实验表明,橡碗栲胶中起稀释作用的主要成份是没食子酸。本文还介绍了一种新的抗高温淡水泥浆稀释剂—KCC产品,该产品在高温下对淡水泥浆的稀释效能超过了DESCO或SMK。 Based on the systematic analysis and comparison of DESCO, a new product in the United States, and the existing SMK product in China, it is proposed that sulfonation should be carried out after chelating with high-valent metal ions to improve the anti-temperature and dilution performance of SMK. Experiments show that the main ingredient of the rubber bowl gum from the role of dilution is gallic acid. This article also introduces KCC, a new high-temperature, fresh-water slurry thinner that outperforms DESCO or SMK in the dilution of freshwater slurries at high temperatures.
