The limestone is very hard. Can it be disinfected by adding water?
Exposure to lime storage can absorb moisture in the air, but the change of mature lime. Changes have been late, not synchronous. Not at the same time the disinfection will not complete, incomplete disinfection, disinfection of nature is not useful. Bacterial virus is active in a field, if not thoroughly disinfected, survived the pathogens re aggregation, reproductive growth, and we think that has been disinfected, produce careless psychology, so one into a retreat, the harm is not worse than failure of disinfection disinfection.
Lime (calcium oxide) do not have direct sterilization ability. Generally we buy lime should be lime and lime is not directly sterilized, only after adding water into lime has the disinfection effect. So do not use lime powder dry and sterilize. One is powder sprinkled uneven will leave a lot of dead bacteria disinfection, virus still survive in the corner, can spread the disease; two will powder dust, lime dust into the animal respiratory tract respiratory tract after moisture absorption, becomes hydrated lime, alkali not only the disinfection time, corrosion will directly harm the respiratory mucosa, animal health. Respiratory disease.
The lime white lumps or powder, the main composition of calcium oxide, calcium hydroxide and water can produce heat, commonly known as slaked lime, strong alkalescence, moisture absorption is very strong. Lime can kill various pathogenic bacteria, but ineffective against spores, mainly used for disinfection of walls, floor, septic tanks and sewage ditch.In actual production, because the lime is cheap, you can buy almost everywhere in rural, and there is no unpleasant smell, white appearance is neat, so widely used. For many years, the author found in contact with the farmers, as, disinfection supplies, lime is often misused to reach disinfection in fact, to find the lime disinfection used regardless of the reason, first of all should be familiar with the characteristics of lime disinfection.
Lime is exposed to air, for a long time, can react with carbon dioxide in the air to produce calcium carbonate, no hydroxyl ion, lost strongly alkaline, will completely lose the sterilization effect. A proper disinfection, the disinfection effect will not keep for a long time.
