Preparation method of active ardealite micropowder based on thermal insulation material
The invention discloses an active phosphogypsum micropowder preparation method based on a thermal insulation material, and belongs to the technical field of gypsum micropowder preparation methods. Thepreparation method comprises the following steps of: S1, phosphogypsum pretreatment; weighing a certain amount of phosphogypsum, and calcining at 200-230 DEG C for 1.5-2 hours. According to the preparation method of active phosphogypsum micropowder based on a thermal insulation material, by adding modified magnesium oxide micropowder, a special moisture-proof agent and calcium stearate, since thecalcium stearate has certain hygroscopicity and waterproofness, the influence of moisture on the active ardealite micropowder can be reduced; meanwhile, the special moisture-proof agent and the modified magnesium oxide micropowder are added, so that the active ardealite micropowder can be subjected to moisture-proof isolation; therefore, the active ardealite micropowder prepared by the preparation method can be completely prevented from being in contact with moisture, an ideal isolation effect is achieved, the active ardealite micropowder is not easy to condense into blocks, and subsequent normal processing of the active ardealite micropowder is guaranteed.
本发明公开了一种基于保温材料的活性磷石膏微粉制备方法，属于石膏微粉制备方法技术领域，其包括以下步骤：S1、磷石膏预处理；称取一定量的磷石膏经过200‑230℃煅烧1.5‑2h。该基于保温材料的活性磷石膏微粉制备方法，通过加入改性氧化镁微粉、专用防潮剂和硬质酸钙，由于硬质酸钙具有一定的吸湿性和防水性，从而可以减少潮气对活性磷石膏微粉的影响，同时专用防潮剂和改性氧化镁微粉的添加可以对活性磷石膏微粉进行防潮隔离，从而使得通过本制备方法制备的活性磷石膏微粉，可以完全避免磷石膏微粉与潮气接触，实现理想的隔离效果，使得活性磷石膏微粉不易凝结成块，从而保障了活性磷石膏微粉后续的正常加工。
