Preparation method of high-strength fire-resistant exhaust passage
The invention discloses a preparation method of a high-strength fire-resistant exhaust passage. The preparation method comprises the following steps: A1) preparing light fireproof mortar; a2) preparing anti-crack mortar; a3) preparing a reinforcing material for later use; (A4) a mold is prepared, and the operation face of a mold plate is coated with a release agent; (A5) anti-crack mortar is plastered and pressed on the surface of the release agent to form an outer surface protection layer; (A6) a reinforcing material is laid on the surface of the outer surface protection layer; (A7) light fireproof mortar is plastered and pressed on the surface of the reinforcing material layer by layer to form a sandwich heat insulation layer located in the middle; (A8) a reinforcing material is laid on the surface of the sandwich heat insulation layer; (A9) anti-crack mortar is plastered and pressed on the surface of the reinforcing material to form an inner surface protection layer; and A10) demolding to obtain a blank body, and conveying the obtained blank body to a curing workshop for wet curing. The prepared thin-wall exhaust passage has the advantages of being high in strength, good in fireproof performance and low in weight.
本发明公开了一种高强耐火排气道的制备方法。其中，制备方法包括步骤A1)配制轻质防火砂浆；步骤A2)配制抗裂砂浆；步骤A3)准备增强材料，待用；步骤A4)准备模具，在模具板的操作面涂刷脱模剂；步骤A5)在脱模剂的表面抹压抗裂砂浆以形成外表面防护层，步骤A6)在外表面防护层的表面铺设增强材料；步骤A7)在增强材料表面逐层抹压轻质防火砂浆以形成位于中部的夹芯隔热层；步骤A8)在夹芯隔热层的表面铺设增强材料；步骤A9)在增强材料的表面抹压抗裂砂浆以形成内表面防护层；步骤A10)脱模后得到胚体，将得到的胚体送往养护车间进行湿养护。本发明所制备的薄壁排气道具有强度高、防火性能好以及重量低的优点。
