由吉林建筑工程学院和长春客车工厂共同研制的镁质装饰板是一种新产品。它不但具有较好的装饰功效,而且具有较好的物理力学性能,解决了同类产品长期存在的返霜和翘曲、变形问题。为解决翘曲、变形及返霜问题,在新型镁质装饰板的研制中主要考虑了以下几个因素。1、菱苦土的活性和安定性。菱苦土(氧化镁)的活性取决于其颗粒大小及结晶程度,与制备时的煅烧温度密切相关。在750~850℃下
The magnesia decorative panel co-developed by Jilin Institute of Architecture and Engineering and Changchun Bus Factory is a new product. It not only has a good decorative effect, but also has good physical and mechanical properties, to solve the long-standing problems of returning frost, warping and deformation of similar products. In order to solve the problems of warping, deformation and returning frost, the following factors are mainly taken into account in the development of the new magnesia decorative panels. 1. The activity and stability of magnesite. The activity of magnesite (magnesium oxide) depends on its particle size and degree of crystallinity and is closely related to the calcination temperature at the time of preparation. At 750~850°C
