Effect of Temperature on the Quality of City Sewage Sludge Shale Brick Products

Abstract:

[Objective] Research on city sewage sludge shale brick in the firing process of crack formation reason, control cracks in the firing process of the brick body, thereby improving the brick product quality, summed up the law of temperature on product quality of city sewage sludge shale brick.[Methods] In order to shale and city sludge as raw material by make bricks, drying and sintering procedure different, to analyze the reason of brick in the process of drying cracks and cracks during the roasting process.[Results] The experimental results show that in the stage of drying and preheating stage if rising too quickly, the sharp increase in the number of brick cracks, resulting in a significant decline in the quality of the finished brick. During the cooling phase if the cooling too quickly, also will increase the number of cracks, leading to reduced quality of brick.[Conclusion] Have an important influence on city sewage sludge shale formation temperature cracks, the control of the temperature is not only reasonable will prevent the formation of crack, but also an effective means to improve the quality of protection brick.
