輕燒鎂粉和重燒鎂粉是什么 What is light burned magnesium powder and reburned magnesium powder

     http://www.hakatayanoodle.com菱鎂礦在不同溫度下鍛燒、熔融后可以生成主成分為氧化鎂的輕燒鎂、重燒鎂和電熔鎂砂。
     菱鎂礦在750-1100溫度下煅燒稱“輕燒”，其產品稱輕燒鎂粉，簡稱為輕燒粉。輕燒鎂粉主要制造膠凝材料，絕熱和隔音的建筑材料，也可做陶瓷原料。
     重燒鎂粉主要是以輕燒粉為原料，經水選、水解、固液分離、干燥、煅燒及粉碎，分級制得。生產重質氧化鎂對輕燒氧化鎂粉質量要求高。一般選用優質菱鎂礦生產的高檔粉，不應有受潮結塊。

 Magnesite can be calcined and melted at different temperatures to produce light-burned magnesium, re-burned magnesium and fused magnesite whose main component is magnesium oxide.

      Magnesite calcined at a temperature of 750-1100 is called "light burning", and its product is called light burning magnesium powder, referred to as light burning powder for short. Light-burned magnesium powder is mainly used for making cementitious materials, heat-insulating and sound-proofing building materials, and also can be used as ceramic raw materials.

      Reburned magnesium powder is mainly made from lightly burned powder, which is obtained through water separation, hydrolysis, solid-liquid separation, drying, calcination and crushing, and classification. The production of heavy magnesium oxide has high requirements on the quality of light-burned magnesium oxide powder. Generally, high-grade flour produced by high-quality magnesite is used, and there should be no agglomeration due to moisture.
