  山东黄锈石材冻融现象的预防,当天然石材毛孔吸收足够的水分时,一旦温度降到0℃以下,天然石材中的水分开始冻结,体积膨胀。当冰的膨胀力大于天然石的结构力时,天然石会产生碎裂。这是石头冻融的现象。
  The prevention of freeze-thaw phenomenon of yellow rust stone in Shandong Province. When the natural stone pore absorbs enough water, once the temperature drops below 0 C, the water in the natural stone begins to freeze and the volume expands. When the expansive force of ice is greater than the structural force of natural stone, natural stone will break up. This is the phenomenon of freezing and thawing of stones.
  首先,黄锈石冻融形成的原因,一般来说,材料是遵循“热胀冷缩”的规律,而水恰恰相反。水的密度在4℃时最大,水分子独立流动。当温度从4°c下降到0°c时,冰中的水分子以一种异常松散的方式以三维的形式排列,这实际上留下了大量的“空”和降低的密度。试验表明,当一立方米的水结冰时,它将增加到1.11立方米。当水进入天然石材孔隙或孔径后遇到寒冷的冰,体积增加,膨胀第二大天然石材或孔径的孔隙,接下来,天然石材inspirates更多的水,毛孔或孔径进一步扩大,这种恶性肿瘤遵循回报,最终导致了天然石材的碎片。
  First of all, the reason for the formation of yellow rust stone freeze-thaw is that generally speaking, materials follow the law of "thermal expansion and contraction", while water is the opposite. The density of water reaches its maximum at 4 C, and the water molecules flow independently. When the temperature drops from 4 C to 0 c, the water molecules in the ice are arranged in an unusually loose way in three-dimensional form, which actually leaves a lot of "empty" and reduced density. Experiments show that when a cubic metre of water freezes, it will increase to 1.11 cubic metres. When water enters the pore or pore size of natural stone, it encounters cold ice, enlarges its volume and expands the pore size of the second largest natural stone or pore. Then, more water, pore or pore size of natural stone inspirates. This malignant tumor follows the reward and eventually leads to the fragmentation of natural stone.

  二、黄锈石材的冻融避免,因为石材冻融破坏的主要因素是水,我们只需要将水阻挡在天然石材中就可以避免石材的冻融破坏。所以,我们只需要使用天然石材保养剂就可以很好地保护天然石材的处置。通过省地质矿产局中心实验室的实施,砷元素的活性度低于或含量趋于零,对人体健康没有影响。适用于建筑内部装饰板材和地板,优于大理石。
  2. Freeze-thaw damage of yellow rust stone is avoided because the main factor of freeze-thaw damage of stone is water. We can avoid freeze-thaw damage of stone only by blocking water in natural stone. Therefore, we only need to use natural stone maintenance agent to protect the disposal of natural stone. Through the implementation of the Central Laboratory of the Provincial Bureau of Geology and Mineral Resources, the activity of arsenic is below or tends to zero, which has no effect on human health. Suitable for interior decorative board and floor, better than marble.
