The present invention discloses an invention. The preparation method of the non-burning brick includes: S1, soaking and cleaning the biomass ash with water; S2, drying the biomass ash; S3, performing a screening and crushing cycle treatment on the biomass ash; S4, performing the screening and crushing cycle The treated biomass ash slag is mixed with the brick-making additives, and dry-stirred to obtain a dry mixture; S5, the dry mixture is added with water, mixed and stirred to obtain a humidified mixture; S6, the humidified mixture is aged chemical treatment; S7, use a brick mold to press the humidified mixture after the aging treatment into non-burning bricks; S8, use boiler exhaust gas to perform high temperature curing on the non-burning bricks; S9, carry out natural curing for the non-burning bricks after high temperature curing . In the preparation method of the unburned brick of the present invention, the boiler exhaust gas is used for high temperature curing of the unburned brick, which can save energy, avoid excessive hydration reaction, enhance the strength of the unburned brick, and ensure the volume stability of the unburned brick. |
