Embodiment 3

[0037] Example 3 Application of Ceramic Thermal Insulation Composite Material

[0038] 1) Clean up the ash on the inner lining of the boiler, and spray the surface with clean water;

[0039] 2) Stir the ceramic heat-insulating composite materials prepared in Examples 1 and 2 evenly, and then spray them on the inner lining surface of the high-temperature boiler respectively, with a spray thickness of 3-5 mm;

[0040] 3) Use a brush to trim the sprayed surfaces of the three boilers to achieve smoothness;

[0041] 4) The sprayed boiler lining is sintered at 600° C. for 2 hours.

[0042] Such as figure 1 As shown, the boiler lining sprayed ceramic insulation composite material is sintered at high temperature to form a ceramic shell. In use, most of the internal heat of the boiler can be reflected and heat transfer to the outside of the boiler can be reduced. Reduce the temperature of the external surface of the boiler and improve the thermal efficiency of the boiler.

Abstract

The invention belongs to the technical field of functional materials, and in particular relates to a ceramic thermal insulation composite material and its preparation method and application. It consists of the following raw materials in parts by weight, 15-40 parts of aluminum dihydrogen phosphate, 5-10 parts of zirconia micropowder, 5-10 parts of magnesia micropowder, 5-20 parts of alumina micropowder, 10-35 parts of ceramic porous microbeads, 5-20 parts of ceramic fiber powder, 5-10 parts of rare earth drier, 10-30 parts of far-infrared ceramic clay, 5-10 parts of bentonite, 10-20 parts of high alumina, 5-10 parts of titanium oxide, deionized water 15‑25 servings. Coating the ceramic thermal insulation composite material prepared by the present invention on the inner lining of the high-temperature boiler can effectively prevent the pulverization of the inner lining of the boiler, and at the same time form a closed protection for the inner lining of the boiler, prolonging the service life of the inner lining of the boiler. The use of ceramic porous micro-beads and micro-bubble materials combined with infrared emitting materials makes the coating play a role of heat insulation and reduces heat loss.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a ceramic thermal insulation composite material and its preparation method and application. Background technique [0002] PetroChina, Sinopec, and power plants for power generation and steam injection heating boiler insulation layer are composed of refractory insulation bricks, ceramic fiber cotton, and castables. The effect of high thermal insulation is limited, the surface temperature of the boiler is high, the damp heat can cause serious loss, the thermal efficiency of the boiler is also reduced, and the powdered dust of the thermal insulation fiber is washed out of the furnace by the flue under the washing of the high-temperature air flow, causing serious pollution to the environment , The insulation layer also needs to be repaired and replaced every year, which causes economic losses to the enterprise. [0003] Therefore, it is an urgent problem to ...
