Calcined magnesium oxide powder for water heater as well as preparation method and application of calcined magnesium oxide powder
The invention provides calcined magnesium oxide powder for a water heater and a preparation method and application of the calcined magnesium oxide powder, and the calcined magnesium oxide powder comprises the following components in percentage by mass: more than or equal to 95% wt of MgO; less than or equal to 1.5% wt of CaO; less than or equal to 0.6% wt of Fe2O3; less than or equal to 0.5% wt of Al2O3; less than or equal to 2.5% wt of SiO2; and less than or equal to 0.2% wt of LOI. The calcined magnesium oxide powder for the water heater has the advantages of high density (the original density is 2.30-2.34 g/cm<3>, and the current density is 2.35-2.38 g/cm<3>) and high flow velocity (the original flow velocity under the condition of 100g of magnesium powder), and a heating tube is filled with the magnesium oxide powder more compactly. The invention also discloses a preparation method of the calcined magnesium oxide powder for the water heater. A calcined heating tube of the water heater prepared from the magnesium oxide powder is long in service life and excellent in insulation and breakdown resistance.
本发明提供一种煅烧热水器用氧化镁粉、其制备方法及用途，本发明煅烧热水器用氧化镁粉，包括质量百分含量如下的各组分：MgO≥95％wt；CaO≤1.5％wt；Fe2O3≤0.6％wt；Al2O3≤0.5％wt；SiO2≤2.5％wt；LOI≤0.2％wt。本发明煅烧热水器用氧化镁粉具有密度大(原有密度2.30‑2.34g/cm3，现在密度2.35‑2.38g/cm3)，流速快(100g镁粉情况下，原有流速为)的优点，填充发热管更加密实。本发明还公开了煅烧热水器用氧化镁粉的制备方法，采用该氧化镁粉制备的煅烧热水器发热管寿命长，绝缘和抗击穿性能优异。
