How to extend the service life of landscape boulders?

landscape boulders claim that they can last for more than 5 years outdoors, so what methods should we use to prolong the service life of landscape boulders?

First of all, anti-aging agents are added to the landscape boulders, and the construction is carried out in strict accordance with the requirements during the stone carving processing and production process to avoid air bubbles, glue accumulation, excessive curing agents, etc. The surface is protected by spray paint to prevent sunlight, weathering and rainwater acid and alkali corrosion, and try to avoid high temperature and excessive temperature difference.
Add UV protection to landscape boulders. A UV absorber is a light stabilizer that absorbs the ultraviolet portion of sunlight and fluorescent sources without altering itself. Since sunlight contains a large amount of ultraviolet rays harmful to colored objects, its wavelength is about 290-460 nanometers, and these harmful ultraviolet rays pass through chemical oxidation and reduction.
In the processing and production of landscape boulders, paste more fiber cloth, resin and better raw materials, the mold card is not too tight, do not need to use a lot of force to hit the plaster, fiber cloth connection, etc., these will improve the Stone Carving steel lifespan.
Resin coatings, reinforced plastics, stone sculpture and their products (stone carving cloth, belts, felts, yarns, etc.) are used as reinforcing materials. A composite material with synthetic resin as matrix material. The concept of composite materials is that one material cannot meet the requirements of use, and it needs to be composed of two or more materials to form another material, that is, a composite material. For example, a kind of stone sculpture, although high in strength, is loose between fibers, can only bear tension, can not bear bending, shearing and compressive stress, but it is not easy to form a fixed geometric shape, it is a soft body. If they are bonded together with synthetic resins, they can be made into various hard products with fixed shapes.
