目前,房屋建筑的门窗框架大都采用木制、钢制或者铝合金材料制做,由山西省菱镁检测中心和山西省长治联合厂共同研制成功了菱镁混凝土门窗框架,将为一般工业和民用建筑提供一种新型的替代材料。该种框架可铰链(合页)各种材料的窗扇、门,或者镶嵌玻璃,并能进行表面油漆等装饰,具有容重轻、强度高,防火防腐的特性。其成本低于木制品15～20%,使用寿命长,特别适用于腐蚀介质严
At present, most of the door and window frames of house construction are made of wood, steel or aluminum alloy materials. Magnesium concrete doors and windows are jointly developed by the Shanxi Magnesite Inspection Center and the Changzhi Joint Factory in Shanxi Province, and will be used for general industrial and civil use. The building provides a new type of alternative material. The frame can be hinged (hinge) sashes, doors, or inlaid glass of various materials, and can be decorated with surface paints, etc., with light weight, high strength, fire protection and anti-corrosion properties. Its cost is lower than wood products 15-20%, long service life, especially suitable for corrosive media
