How to avoid the frost cracking of the stones along Wulianhua Road.

The main cause of the freezing and cracking of the Wulianhua Road edge stones is water. To prevent water from entering the gaps of the Wulianhua Road edge stones, it can effectively avoid the occurrence of freezing of the Wulianhua Road edge stones. Therefore, it is necessary to use Wulianhua curbstone maintenance agent for protection. The protective Wulianhua curbstone on the outer surface can more effectively prevent the occurrence of frost cracking.

Usually, when the temperature changes, the phenomenon of "thermal expansion and contraction" occurs, and the characteristics of water are exactly different. The water density is high at 4 degrees Celsius, and water molecules will flow independently. When the temperature drops from 4 ℃ to 0 ℃, ice formation occurs, and the water molecules in the ice form a three-dimensional structure, arranged in an abnormal sequence pattern. This layout is prone to leaving many "gaps", and the density will decrease. Experiments have shown that when 1 cubic meter of water freezes, its volume increases to 1.10 cubic meters. At 0 degrees Celsius, water enters the micropores or crevices of the Wulianhua Road stone and freezes, increasing in volume and expanding the micro pores in the stone. Then, the Wulianhua Road stone absorbs more water into the micropores, further expanding the pores and gaps. This cycle repeats, causing cracks in the expansion of the Wulianhua Road stone.
