Table 4 Advantages and drawbacks of the four reinforcing materials for color painting in ancient architecture
Reinforcing materials | Advantages | Drawbacks | Better reinforcing effect on pigments |
|---|---|---|---|
B72 | Better hydrophobicity Better transmittance | Lower permeability Excessive tensile strength Less smooth film | Carbon black |
AC33 | Better transmittance Better permeability Fair tensile strength Smooth film | Lower hydrophobicity | Carbon black, Cinnabar |
FKM | Better hydrophobicity Better transmittance Less smooth film | Lower permeability Low tensile strength | Paris green, Lead white |
FEVE | Better hydrophobicity Better transmittance Better permeability Fair tensile strength | Less smooth film | Cinnabar, Paris green, Carbon black |
