Gypsum Free Sample 聽 聽 1.聽Product Introduction There are three kinds of gypsum retarder chemical, named聽phosphogypsum, FGD gypsum, fluorine gypsum. Among these three kinds of chemical gypsum retarder, fluorine gypsum is a green buliding materials, because it has no radiation and formaldehyde. Phosphyogypsum have too many impurities and if the impurities can not be well treated, it will cause damage to human body and environment. FGD gypsum have too many factors to effect the quality, so the quality of FGD gypsum in the market is ragged. Therefore, fluorine gypsum is the best gypsum retarder. 2.聽Product feature and application 聽 Fluorine gypsum is mainly used in cement additive, concrete additive, tubular pile additive, gypsum based self-leveling, gypsum block, gypsum plastering, bricks and tiles, lithium battery and so on. 3.聽Production聽details聽 Characteristics of fluorine gypsum: A. The radioactive specific activity of fluoro-gypsum is much lower than the national standard. B. The content of HF is stable at 180-230 degrees when fluorine gypsum聽is formed, while hydrogen fluoride is extremely volatile at room temperature and can be recycled by the waste gas recovery device in production, so hydrogen fluoride will hardly remain in the slag at this temperature. C. The fluorine element in fluoro-gypsum exists in the form of CaF2, which is insoluble in water, and its content is less than 1%, so it does not cause harm to the environment and human body. D. Fluoro-gypsum itself has no activity, it is necessary to add lime, modifier, activator and other additives to increase the activity of fluoro-gypsum, so the quality of fluoro-gypsum is very stable. E. Fluoro gypsum does not contain radiation and formaldehyde, which belongs to green building materials. Fluorine gypsum in cement additive can reduce energy consumption, play a important role in environmental protection. We provide fluorine gypsum raw material, 100mesh, 200mesh and 325mesh fluorine gypsum for our customer. And the PH value can be customized by your demands. 聽 4.聽Deliver,shipping and servcing 聽 Packing: 1 ton / space bag or bulk Delivery way: sea transport Sample: free sample Service: 24/7,win-win cooperation 聽聽聽聽聽聽聽Gypsum Free Sample website:http://www.xuexgypsum.com/gypsum/
