玻璃丝棉
耐高温玻璃棉的设备施工 在设备表面提前焊上铆钉，再用铁丝把高温玻璃棉捆绑在设备表面，当所需保温的设备的设备温度超过250℃时，最好采用双层保温方式，内外两层玻璃棉的接缝处应该分开，以免产生热桥造成热量损失。当所需要保温的设备温度超过400℃时，建议内层用一定厚度的硅酸铝，外层用耐高温玻璃棉，两层之间的接缝也应该错开。最后在外面包上外裹层，既可以保护玻璃棉，又达到美观效果。
Recommendations for the works with Refractory Glass Wool products
First，weld pins to the surface of the equipment in advance and then tie the refractory glass wool over the surface of the equipment。If temperature of the equipment is above 250℃，it is recommendable to adopt double-layer heat preservation method。Make sure that the seams of the outer and inner layers of glass wool are staggered to avoid heat loss due to the heat bridge formed。If temperature of the equipment exceeds 400℃，it is recommendable to use aluminum silicate for the inner layer and
Refractory glass wool for the outer layer，also staggering their seams。Finally，wrap the outer cover layer which serves both as protection to the glass wool and decoration。
