The absorption rating refers to how porous a given material is. The more absorbent it is, the more susceptible the stone will be to stain. Absorbent stone can also be prone to cracking damage if it is subjected to freezing conditions. Natural stones vary greatly in their absorption rates, with sandstone being the most porous and granite the most impervious to water absorption. Absorption rates are classified according to the following terms:
In general, sandstone is the most porous natural stone material. Travertine, limestone, and 石板 have medium absorbency, while granite is relatively waterproof. Polished materials also absorb less water than honed or cleft surfaces.
一些零售商使用分级系统来评估材料的质量。这可以指瓷砖的尺寸、形状和厚度,以及其表面的状况。大多数分级系统有三个质量等级:
这衡量了各种材料的防滑程度。系数越高,瓷砖的牵引力就越大。这个数字在浴室和厨房等潮湿环境中以及人流量大的商业区尤其重要。《美国残疾人法案》要求地板材料的防滑系数至少为 0.6 干燥系数。
有些天然石材地板材料比其他材料更适合户外应用。上述许多因素将决定某种材料是否应在露天环境中使用。
Natural stone materials are formed beneath the earth over millions of years, and often contain a variety of disparate elements. Sometimes iron is present in these materials, which can manifest as bright red and amber hues in the surface of the stone. The problem in an outdoor environment is that those traces of iron can oxidize, a process more commonly known as rusting. This can cause the entire tile to degenerate over time.
有许多美学和实用的原因使天然石材地板成为一个很好的选择:
使用天然石材也有一些缺点:
购买天然石材地板材料时,务必进行研究并了解所购买材料的特性。了解它是否适合您的特定用途以及需要多少维护。在购买之前,请咨询零售商并彻底研究石材。
