摘要
研究了一种新型耐火风管的制造方法,探讨了在一定的工艺条件下耐火风管主材-无石棉硅酸钙板的模压成型配方。结果表明,研制的无石棉硅酸钙板具有密度较低、强度较高、高温线收缩率小的特性,设计、制造的新型耐火风管的耐火极限大于2.5h。
A method for manufacturing fire duct was investigated. By a given moulding technique condition, the details of contents for producing asbestos-free calcium silicate board, the primary material for the fire duct, were discussed. The results show that, the said board has excellent physical characteristics, and the fire duct has a fire endurance time of not less than 2.5 h.
