We often see some white crystals in the joints from the flow out of stone, which is commonly known as "white China" (Pan-base). Bai Hua is divided into two types, one quot; a white China ", one is the" second Bai Hua. " "A white China" is caused by the construction, chemical changes of cement mortar to form calcium hydroxide, from the stone coming out the seams in the stone itself or from the lines, pores at coming out, and carbon dioxide in the air combine to form white crystals; "second white China" mainly due to rain inside with cement mortar into contact with the stone, resulting in the formation of chemical change Bai Hua. These two powerful scavengers to remove. Generally speaking, remedial and prevent regeneration of white to be from different areas of China.
