The invention discloses a preparation process of a zirconium silicate ball filler. The preparation process comprises the following steps of: step 1, adding zircon sand, alumina powder, a fluxing agentand charcoal powder into an aqueous solution, and mixing the materials to form a mixture; 2, introducing argon into a hearth for atmosphere protection, gradually adding the mixture into the hearth, and heating the mixture to be in a molten state, and forming a molten mixture; and step 3, pouring the mixture in the molten state out of the hearth, blowing the molten mixture flowing out of a launderof the hearth by using compressed air, blowing the molten mixture into balls, performing cooling, solidifying and heat preservation to obtain zirconium silicate ball fillers with different particle sizes. The zirconium silicate ball filler provided by the invention has compressive strength of more than 30MPa, strong acid corrosion resistance and impact toughness, and micron-sized through apparentporosity of 25-40%, and is suitable for chemical industry, water treatment filtration and inorganic salt adsorption.
本发明公开了一种硅酸锆球填料的制备工艺，包括以下步骤：步骤1：将锆英砂、氧化铝粉、助熔剂、木炭粉加入水溶液混合形成混合料；步骤2：在炉膛中通入氩气进行气氛保护，将混合料逐步加入到炉膛中，加热混合料至熔融状态；形成熔融混合料；步骤3：将熔融状态的混合料从炉膛内倒出，用压缩空气喷吹从炉膛的流槽流出的熔融混合料，将熔融混合料喷吹成球，冷却凝固和保温后得到不同粒度的硅酸锆球填料。本发明的硅酸锆球填料耐压强度大于30MPa、耐酸腐蚀、抗冲击韧性强、微米级贯通显气孔率25‑40%，适合于化工行业及水处理过滤以及无机盐吸附。
