The treatment method of Bai Hua in stone material
Mar 24, 2021
We often see some white crystals flowing out of the joints of the stone, which is commonly known as "Bai Hua" (Pan alkali).Baihua is divided into two kinds, one is "a Baihua", one is "two Baihua"."A Bai Hua" is the cause of construction, cement mortar chemical changes to form calcium hydroxide, from the joint of the stone or from the stone itself lines, pores emerge, and carbon dioxide in the air combined to form white crystals;"Two Baihua" is mainly due to rain infiltration into the stone interior and cement mortar contact, chemical changes and the formation of Baihua.These two powerful scavengers to remove.
Generally speaking, to remedy and prevent the regeneration of Baihua should start from many aspects.First of all, to prevent external pollution that is, the infiltration of rain water, which can be from the stone surface for protective treatment and strengthen the waterproof function of the joint part to start, as long as the outside of the water is no longer infiltrated into the stone, and there is no water in the stone, Baihua is unable to regenerate.
