Technical Field

The invention belongs to the technical field of seedling raising equipment, and particularly relates to a preparation method and a device of a heat preservation coating.

Background

In order to achieve the service performance of the hard felt under various conditions, the hard felt is usually subjected to surface treatment, i.e. a layer of other substances is covered on the surface of the hard felt, such as graphite paper or the like is stuck on the surface of the hard felt. The existing surface treatment methods for the hard felt generally comprise carbon-coated cloth, graphite-coated paper and the like, and although the methods can solve the problem that the hard felt is easy to fall off in the use process, volatilization of the surface C of the hard felt cannot be avoided under the high-temperature use condition, and particularly in a polycrystalline furnace and a single crystal furnace, the volatilization of the C can influence the quality of products. In order to solve the problems, a coating is required to be manufactured on the surface of the hard felt, the thickness of the glue solution is inconvenient to adjust when the glue solution is covered in the process of manufacturing the coating, and sand paper is required to be replaced for polishing again after polishing by a polisher. The back of abrasive paper realizes self-adhesion with the polishing dish (bonding dish) of polisher, needs the manual work to tear old abrasive paper when changing abrasive paper, packs into new abrasive paper, and the manual replacement's speed is slow, has influenced the promotion of machining efficiency, in view of this, has the case to produce.
