摘　　要：乳酸生产副产石膏废渣是乳酸生产工艺复分解反应过程中产生的副产物。为了发展循环经济,建立资源节约型、环境友好型企业,对乳酸石膏废渣进行综合利用,做到变废为宝;同时,也为了减轻石膏废渣堆场的堆置处理压力,降低乳酸生产成本,开发出一条利用乳酸副产石膏代替天然石膏生产纸面石膏板的重要途径。Waste gypsum residue produced by lactic acid is a by - product in the process of lactic acid production complex decomposition reaction. In order to develop circular economy,build a resource conser- ving and environment -friendly enterprise,lactic acid gypsum waste residue is comprehensively utilized, and waste to treasure. Meanwhile, in order to reduce the stack handling pressure of gypsum residue dump, reduce the production cost of lactic acid, an important way to produce gypsum board using lactic acid by - product gypsum instead of natural zvosum is develooed.
