                      石材翻新機物理作用造成石材風化因素

                      信息來源于:互聯網 發布于:2022-03-31

                      1.石材翻新機低等植物的作用:在有水、溫度適宜的條件下,苔蘚、霉菌等有機物的孢子囊著附在石材的表面,開始發育生長,使石材表面形成各種各樣的有機的色斑,這些有機物為了生存,與空氣中的二氧化碳、二氧化硫、二氧化氮等物質相抗爭,改變石材的表面紋理結構。另外,這些植物死后與水形成有機酸而加速石材的老化,使石材產生剝蝕的現象。

                      2.熱能的作用:石材因日間受熱而膨脹,夜間受冷而收縮,產生熱脹冷縮現象,且石材中含有許多不同的礦物質,其膨脹系數不同,而發生粒狀剝蝕或塊狀的崩解。

                      3.粘裂作用:膠粘是石材安裝方法中的一種,其殘留在石材表面的粘膠因老化作用使粘接石材的膠結礦物產生松弛作用,使石材內部松弛,表面易剝落,從而加速石材的老化。

                      4.石材翻新機紫外線的照射:石材本身具有許多毛細孔,且毛細管越小毛細現象越顯著。因此,石材吸水后,在陽光(紫外線)的輻射下,水份在石材的毛細孔中的蒸發速度隨之加快,水份中帶有對石材侵蝕的物質對石材的侵蝕速度也會加劇,從而引起石材的老化。
