與耐久性有關的因素有哪些 耐火磚?

耐火磚耐久性的物理效應一般指乾濕變化、溫度變化、凍融循環等。 這些影響會導致材料體積發生變化或引起內部裂縫擴大，材料會逐漸被破壞。

Chemical effects include the corrosive effects of aqueous solutions of acids, alkalis, salts and other substances and harmful gases. These corrosive effects will cause materials to gradually deteriorate and be destroyed.

The biological effect of the durability of refractory bricks refers to the infestation of fungi and insects, including the destruction of materials due to moth-eaten and decay. Therefore, the durability of a material is actually a measure of the material’s ability to maintain its original properties for a long time under the above-mentioned multiple actions to ensure safe and normal use. In actual engineering, the material is often affected by multiple destructive factors at the same time. The quality of the material is different, and the content of its durability is different.

耐火磚往往是由化學作用、溶解、凍融、風蝕、溫差、濕度差、摩擦等因素或多種因素共同作用引起的。 其耐久性指標包括更多的抗凍性、耐候性和抗滲性。 ，耐磨性等方面，同一種材料的耐用性不是靜態的。
