石灰的灭菌(消毒)作用如何?必须从理论上弄通,正确使用,才能达到杀菌的目的.干石灰粉是石灰石(碳酸钙)经高温灼烧失去二氧化碳后生成的氧化钙,再经粉碎后便是商品石灰粉(生石灰),它在干燥状态下无法发挥作用,故一般说它无消毒作用.石灰粉加水虽然生成氢氧化钙(熟石灰),但在干燥情况下仍不能表现出硷性,无杀菌作用.只有在接触到很湿的物体如霉菌或水溶液,才能显示硷性,具杀菌作用.因为任何微生物生长都有其合适的pH值,pH在12以上都无法生长而死亡.这就是石
Lime sterilization (disinfection) effect? Must be theoretically figured out, the correct use, in order to achieve the purpose of sterilization. Dry lime powder is limestone (calcium carbonate) calcined at high temperature loss of carbon dioxide generated after calcia, and then crushed After the product is lime powder (quicklime), it can not play a role in the dry state, it is generally said that it has no disinfection effect.Although the lime powder plus water to generate calcium hydroxide (hydrated lime), but in dry conditions still can not show alkaline , No bactericidal effect.Only in contact with very wet objects such as mold or water solution to show the alkaline, with a bactericidal effect.As any microbial growth has its proper pH value, pH above 12 can not grow and die.
