Environment is particularly more, common are construction building site, machine-building factory, hot-working factory building etc., therefore the housing of environmental protection equipment
Meeting is oxidized or corroded rapidly, long in the prior art to use one layer of coating of formation outside housing to be used to protective housing.Prior art
The conventional coating of the equipment of middle environmental protection industry (epi), including artificial brushing or equipment spary coating type are formed, and its film layer is relatively thin, the production brushed
Product are generally water-soluble mixing liquid, due to this coating using after artificial brush with protected object surface affinity is small, molecule it
Between space it is larger, intensity is relatively low, repeatedly heating cooling after obscission occurs.And manually brushing film forming thickness is uneven,
If brushing film forming is thicker, ftractures more serious, then come off more serious, adhesive force is smaller；And it is serious to ftracture and be cracked, then it can cause
Heat radiation intrusion can not protect protection object well, not reach expected effect, not have the work of excellent fire retardant anticorrosion erosion
With；Moreover, this coating surface rents rough still extension nitre, hangs with a large amount of attachments, the protection is easily destroyed when clearing up the attachment
Layer；In addition, the drying of coating needs the special large-scale equipment with larger drying/anneal chamber, it is difficult cost-effective.
How to accomplish that protected object surface does not weather, housing or liner do not weather and deform generation destruction, are always
The theme of field people research.Although the coating variety of current domestic application is various, the problem is not solved systematically.
