Abstract

The invention discloses a method for preparing an urban sludge ceramic heat collection panel. The urban sludge ceramic heat collection panel is characterized by consisting of three parts, a heat collection layer (1), a transition layer (2) and a thermal insulation layer (3). According to the urban sludge ceramic heat collection panel disclosed by the invention, light waves of each frequency can be fully captured under irradiation of sunlight, so that the surface temperature of the urban sludge ceramic heat collection panel is 100 DEG C, and the thermal conversion capacity can be over 95 percent. With the adoption of once-firing, the transition layer is arranged between the heat collection layer and the thermal insulation layer, so that the defects that the pore diameter is extremely large and the bonding strength and thermal shock resistance are reduced between the heat collection layer and the thermal insulation layer due to inconsistent melting points of materials are effectively overcome. Ceramic colorants are added, so that urban sludge ceramic heat collection panels of various colors such as a single color and composite colors can be prepared, the production process is simple, the cost is low, and the heat collection effect is good.

Description

technical field [0001] The invention relates to a method for preparing an urban silt ceramic heat collecting plate, belonging to the technical field of ceramic preparation. Background technique [0002] Urban silt ceramic heat collector panels will generate a lot of heat energy when they are irradiated by sunlight. The salt industry in coastal areas still uses the traditional method of drying salt in salt pans, which is less efficient. Contents of the invention [0003] The purpose of the present invention is to provide a kind of preparation method of urban silt ceramic heat collecting plate with high heat collecting function and low production cost, its technical scheme is: [0004] A method for preparing an urban silt ceramic heat collecting plate. The urban silt ceramic heat collecting plate is composed of three parts: a heat collecting layer (1), a transition layer (2) and an insulating layer (3). The specific method includes the following steps: [0005] a. Prepara...
