Problems solved by technology
[0002] Some pipelines transporting high-temperature fluids require high-temperature resistance. At this time, direct use of various heat-resistant steels will not only cause oxidation and corrosion of various heat-resistant steels, reduce the service life of the pipelines, but also cause a large amount of heat to be dissipated into the air, causing transportation The temperature of the fluid decreases, which will affect the fluid temperature and cause production difficulties and waste of energy if the fluid temperature does not meet the production requirements.
In order to reduce fluid resistance, all kinds of fluid pipelines are generally cylindrical structures. If this structure adopts formwork and pouring construction methods, it is more difficult. If bricklaying methods are used, various special-shaped bricks will be used, resulting in construction costs. and material costs will increase significantly
[0003] In addition, due to the low volume density of the existing spray coatings, different volume shrinkages will be caused during use, or uneven potholes will be formed inside the pipeline, which will increase the resistance of the transported fluid and reduce the output of the transport.

Embodiment 1
[0036] Use the ingredients in formula 1, stir evenly for 5 minutes, then spray and apply, and dry and harden naturally within 40 minutes; natural curing for 6 hours. The method can be sprayed quickly without form support, does not cause volume shrinkage after use, can ensure the smoothness of the pipeline, and has low cost at the same time.
Embodiment 2
[0038] Use the ingredients of formula 2, add water and stir evenly for 5 minutes, then spray and apply, and dry and harden naturally within 25 minutes; natural curing for 4 hours. The volume does not shrink after use, which can ensure the smoothness of the pipeline.

Abstract
The invention relates to pipeline spray paint and a using method thereof, and belongs to the field of a refractory material. The pipeline spray paint comprises the following components in parts by weight: 38-58 parts of light weight alumina brick, 3-9 parts of raw perlite, 10-20 parts of portland cement, 20-30 parts of silica powder, 5-8 parts of ball clay and 1-3 parts of wood calcium powder. The pipeline spray paint is fast and practical and does not need to be specially maintained during using; and after the spray pain is used, the volume of the pipeline spray paint does not shrink, and the smoothness of pipelines can be ensured.
