Problems solved by technology

However, there are many problems in the prior art for the restoration of old buildings.

[0004] The best repair method in the existing technology is to restore the old, that is, the repair materials themselves are the available raw materials left after other ancient buildings are damaged; the old repair method can restore the current state of the ancient buildings to the greatest extent. Natural appearance, because the raw materials used are also old materials, it can restore the old buildings in a real and natural way; but this repair method is not a long-term way, which itself requires the use of old building materials, which depends on continuous discovery The ancient architectural relics should be cleaned up with available raw materials. The number of raw materials is limited and will become less and less as they are used. The cost of old materials themselves is relatively high, and as the quantity decreases, it will become more and more expensive, which will greatly improve Restoration costs of old buildings

In addition, poor adhesion and bonding between layers of old paint will cause paint film peeling, peeling, drumming, peeling and other pathological phenomena, which will seriously reduce the service life and require frequent restoration of ancient buildings
