Shandong Shrimp Red Company's products are widely used across the country. However, due to varying climatic conditions, the company's stone products in northern regions face unique challenges during maintenance. With lower temperatures in winter, the Shrimp Red stone from Shandong is prone to freeze-thaw phenomena. What should be done in such situations?

Shandong Xiaohong Company analyzes that frost-thaw phenomena mainly occur in areas closer to the north where the weather is relatively cold. Once the capillaries of the stone absorb sufficient moisture, when the temperature drops below 0°C, the moisture in the stone begins to freeze and expand in volume. When the expansion force of the ice exceeds the structural strength of the stone, the stone will crack. This is the frost-thaw phenomenon.

Shandong Xiaohong Company analyzes that the pores or gaps in the stone products freeze upon contact with cold, causing the volume of the stone products to expand due to external environmental influences. This expansion leads to the widening of the pores or gaps in the stone. Subsequently, the stone absorbs more water, further widening the pores or gaps. This vicious cycle ultimately results in the cracking of Shandong Xiaohong Company's stone products. The primary factor causing the freeze-thaw in Shandong Xiaohong Company's stone is water. By preventing water from entering the stone, we can prevent freeze-thaw from occurring. Therefore, it is sufficient to apply a stone maintenance agent to provide protective treatment for Shandong Xiaohong Company's stone products.
