Problems solved by technology

[0002] At present, most of the primary curing of tobacco leaves in my country is carried out in small curing rooms. Although more advanced centralized tobacco curing rooms or intensive tobacco curing rooms have been built in some areas, the energy used is still coal and firewood as heat sources. Most of the fire tubes used are made of bricks or cement, with high energy consumption, low thermal efficiency, long curing time, and uneven quality of cured tobacco leaves.

Embodiment Construction

[0013] Raw materials are prepared by weight percentage in Table 1, and the sum of each raw material weight ratio in each embodiment is 100%.

[0014] Table 1

[0015] Raw materials:

[0016] The preparation process is as follows: the raw materials listed in Table 1 are all in powder form, after mixing and fully stirring, they are placed in a muffle furnace and sintered at a high temperature of 700-1000°C to form microporous ceramics, cooled, crushed into small pieces, and put into a ball mill The medium ball mills to 100-300 mesh and sieves, and the undersieve is taken as dry infrared radiation coating powder. Infrared radiation paint dry powder needs to add 25-45% composite binder prepared by adding 10-15% silica sol to water glass, adjust it to a thin paste, brush on the upper surface of the fire tube, and use it after drying . When the paint adjusted to a thin paste is too thick, you can add an appropriate amount of water, mix well and use it. Among them, manga...

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an infrared radiation coating used in a tobacco curing room and a preparation method thereof. Background technique [0002] At present, most of the primary curing of tobacco leaves in my country is carried out in small curing rooms. Although more advanced centralized tobacco curing rooms or intensive tobacco curing rooms have been built in some areas, the energy used is still coal and firewood as heat sources. Most of the used fire tubes are made of bricks or cement, which consumes a lot of energy, has low thermal efficiency, takes a long time to bake, and the quality of the cured tobacco leaves is uneven. People began to use infrared coatings on the fire tubes to improve energy thermal efficiency and product quality, and save energy. It has been found that some infrared materials can emit the effective band of heating objects in the electromagnetic band, and have the...
