High-temperature-resistant anti-corrosion concrete flue and preparation method thereof
The invention discloses a high-temperature-resistant and anti-corrosion concrete flue. The high-temperature-resistant anti-corrosion concrete flue sequentially comprises a high-temperature-resistant anti-corrosion layer, a heat insulation protection layer, a heat-resistant anti-seepage layer and a structural layer from inside to outside. Through the combined action of all the layers, acid-base gas and water vapor in smoke are effectively prevented from invading the structural layer, transfer of smoke heat is blocked, the surface temperature of the structural layer is made to be close to the environment temperature, and the problem that the structural durability is affected due to microcracks caused by thermal stress of the structural layer under the high-temperature-difference condition is effectively solved; therefore, the obtained concrete flue has the characteristics of high temperature resistance, corrosion resistance, strong bearing capacity and the like, is good in overall combinability, high in volume stability and long in service life, and is suitable for smoke discharge components of civil and industrial buildings.
本发明公开了一种耐高温防腐蚀混凝土烟道。本发明的耐高温防腐蚀混凝土烟道由烟道内部到外部依次为耐高温防腐层、隔热保护层、耐热防渗层和结构层。本发明通过各层的共同作用，有效阻止了烟气中的酸碱气体和水蒸气侵入到结构层，并且阻隔了烟气热量的传递，使结构层的表面温度近于环境温度，有效避免了结构层在高温差条件下因热应力导致的微裂纹，进而影响结构耐久性的问题，使得所得的混凝土烟道具有耐高温、防腐蚀、承载能力强等特点，并且整体结合性好，体积稳定性高，使用寿命长，适用于民用和工业建筑的排烟构件。
