A, freeze-thaw reasons
Stone freeze-thaw phenomenon mainly in near the north where the weather colder. When stone wool stoma after absorbing enough water, once temperatures dropped to below 00C began to freeze the water, stone, volume happens to inflation. When ice expansion ability than stone structure force, stone material can produce fracture. This is freeze-thaw phenomenon.
Generally speaking, the matter is abide by the "heat bilges cold shrink" law, and the water is just the opposite. Of the density of water at 4 ℃ maximum, water molecules have liquidity operate independently. Water is composed of 4 ℃ to 0 ℃, the temperature drop a molecule of water, ice is arranged in a three-dimensional pattern, this form of abnormal loose structure form actually left many "hole", density instead decrease. Experiments show that, when the water turns into ice 1M3, the volume will increase after to 1.11 M3. So when the water enter stone pores or aperture freeze, encounter cold after the increase in size, thus swell of stone material, then, or aperture pore water, stone inhale more pores or aperture be further swell, so vicious followed eventually led to the stone, the fracture.
Second, freeze-thaw prevention
Because the main factor is thawing produced water, we just stop water into the stone can prevent the occurrence of thawing. So, we'll just use stone conservation agent will stone well protective processing line.
