[0029] Example: as attached Figure 1-7 As shown, a special micro-expansion corundum wear-resistant paint for waste heat air ducts, including wear-resistant aggregates, composite expansion agents and plastic sintering aids, the wear-resistant paint is applied on the tortoise shell net a for use in waste heat air An inner liner c is formed in the pipe b.
[0030] In this embodiment, wear-resistant aggregates are used instead of ordinary aggregates in the prior art to ensure that the inner liner c has outstanding wear resistance, so that the inner liner c contains a large amount of solid particles It can remain effective for a long time under the dust, and the composite expansion agent has the characteristics of micro-expansion when heated, which is different from the characteristics of shrinkage of the existing wear-resistant coatings at high temperatures in the prior art, so that the wear-resistant coatings in this embodiment are used During the process, the tortoise shell ne...
