Anti-cracking maintenance method of carbon mineralized product
The invention provides an anti-cracking carbon mineralization maintenance method which comprises the following steps: putting a prefabricated product blank for carbon mineralization into a carbonization device, introducing industrial tail gas, and controlling the pressure of the industrial tail gas, the moisture content of the industrial tail gas, the carbon mineralization temperature and the carbon mineralization time, so as to obtain the anti-cracking carbon mineralization maintenance method. And performing a carbon mineralization maintenance process in stages and periods on the carbon mineralization process of the prefabricated product. According to the method, the pressed and formed blank is placed in the carbonization kettle, industrial tail gas is introduced, and staged periodic maintenance is performed on the carbon mineralization process of the prefabricated product by controlling the maintenance environment temperature, moisture content and gas pressure, so that the product is not cracked in the carbonization process. According to the anti-cracking maintenance method provided by the invention, moisture evaporation and carbonization expansion in the carbonization process are controlled by controlling moisture content, temperature and pressure in different carbonization stages, the problem of cracking of current carbon mineralized products is solved, the carbonization rate of the products can be improved, the bending strength reaches 7-23 MPa, and the compressive strength reaches 60-150 MPa.
本发明提供了一种防开裂的碳矿化养护方法，包括以下步骤，将用于碳矿化的预制品毛坯置于碳化装置内，通入工业尾气，通过控制工业尾气的压力、工业尾气的含湿量、碳矿化温度以及碳矿化时间，对预制品碳矿化过程进行分阶段周期的碳矿化养护过程。本发明将压制成型的毛坯置于碳化釜内，通入工业尾气，通过控制养护环境温度、含湿和气体压力对预制品碳矿化过程进行分阶段周期养护，实现制品在碳化过程不开裂。本发明提供的防开裂养护方法在不同碳化阶段养护控制含湿、温度和压力大小的方式控制碳化过程水分蒸发和碳化膨胀，解决当前碳矿化制品开裂的问题，可以提高制品碳化率，抗弯曲强度达到7～23MPa，抗压强度达到60～150MPa。
