Introducing the various types of Luhei stone protector

Introducing the types of Lühui Stone Protector available.

Limestone defects such as sand holes, pits, and cracks on the surface can affect the decorative effect of the limestone, diminishing its aesthetics and value. To save on this, a common method is to use adhesive glue for repairs. Examples include repairing limestone. However, there are still many issues with using epoxy resin materials. Limestone sealant protectants refer to those that can be applied to the surface of the limestone, forming a protective film to repel water, oil, and dirt, thus enhancing the chemical properties of the stone for decoration. These protectants come in water-soluble, organic solvent, and solid types. The surface types of these protectants are categorized as temporary.

Temporarily sealed protective agents essentially involve applying a film to the surface of the stone, which is not securely attached and can be removed. These products in the general market are water-based compositions made of polymers containing chemical components, and they are not actual stone materials. Special protective agents for early-stage stone were not available. Some individuals have also used roof waterproofing coatings as stone protective agents, which can achieve certain protective effects.

The protective agent for Luhei stone can be used with mixed sand to repair low-viscosity epoxy resin. The bonding effect shows that the initial penetration and bonding strength are good, but testing instruments have discovered micro-cracks on the bonding surface between marble and epoxy resin. This is related to the creep of the epoxy resin on the stone surface. Traditional Luhei stone repair agents mostly use solvent evaporation methods, which have longer curing times and are not suitable for rapid industrial processes. The bonding and repair of Luhei stone are the main techniques for stone restoration and also a significant means of maintaining Luhei stone.
