Gypsum modifier as well as preparation method and application thereof
The invention discloses a gypsum modifier as well as a preparation method and application thereof, and belongs to the technical field of treatment of gypsum prepared by desulfurization in a power plant. The gypsum modifier provided by the invention is prepared from the following raw materials in parts by weight: 50-55 parts of a component A surfactant, 15-20 parts of a component B dispersant and 25-35 parts of a component C penetrant, the surfactant is one or more of polymerization products of high carbon alcohol-isomeric alcohol C18 or high carbon alcohol-isomeric alcohol C19 or high carbon alcohol-isomeric alcohol C20 and 1, 2-cyclopentane dicarboxylic acid; the penetrating agent is one or more of polymerization products of high-carbon alcohol-isomeric alcohol C13, high-carbon alcohol-isomeric alcohol C14 and polyacrylic acid; and the dispersing agent is selected from one or more of binary polymerization products of formic acid or acetic acid or caproic acid and methyl acrylate. The technical problem that in the prior art of limestone wet separation, the moisture content of gypsum is large when the gypsum is separated through a vacuum belt conveyor is solved.
本发明公开了一种石膏改良剂及其制备方法与应用，属于电厂脱硫制取石膏处理技术领域。本发明提供的石膏改良剂，以重量份数计，由以下原料组成：A组分表面活性剂50份‑55份、B组分分散剂15份‑20份、C组分渗透剂25份‑35份；表面活性剂为高碳醇‑异构醇C18或高碳醇‑异构醇C19或高碳醇‑异构醇C20与1，2‑环戊烷二羧酸的聚合产物中的一种或几种；渗透剂为高碳醇‑异构醇C13、高碳醇‑异构醇C14和聚丙烯酸的聚合产物中的一种或几种；分散剂选自甲酸或乙酸或已酸和丙烯酸甲酯的二元聚合产物的一种或几种。解决石灰石湿法脱离现有技术中使用真空皮带机脱出石膏时石膏含水率大的技术问题。
