How much is quicklime per ton? An analysis of the correct methods for using it in livestock disinfection
Quicklime, whose main component is calcium oxide, can be produced from any natural rock composed mainly of calcium carbonate, such as limestone, chalk and dolomitic limestone.So how much does quicklime cost per ton? How should it be used correctly in livestock farming for disinfection? According to Mr. Li, a building materials dealer in Changsha, the price of quicklime powder is roughly between 200 and 500, depending mainly on the intended use, the calcium content and the requirements for molybdenum content.
How should quicklime be used correctly in livestock farming for disinfection?
Quicklime is easy to obtain, affordable and easy to buy, and has strong disinfecting power. It is a non-polluting disinfectant and is favored by many livestock farmers. However, because many farmers use it improperly, it often fails to truly achieve the purpose of disinfection and sterilization. Therefore, the following points should be noted on how to use quicklime correctly for disinfection.
1. The correct method for disinfecting with quicklime powder. For disinfection of livestock and poultry farms, add water to quicklime to prepare a 10%-20% lime milk, and spray it at a rate of 2-6 liters per sq m. This can disinfect roads, barn walls, floors, ceilings, livestock pens and so on. Using 1 kg of quicklime and adding 350 ml of water to make slaked lime powder for spreading can disinfect damp ground, manure pits and sewage ditches. At the entrance of livestock and poultry farms, wet straw bags or wet burlap sheets soaked in 20% lime milk can be placed, replaced once every 3 days, to disinfect shoe soles, wheels and so on.
2. Do not spread quicklime powder directly and dry on dry ground for disinfection. This is because quicklime cannot disinfect directly. Its main component is calcium oxide, and only after adding water to form calcium hydroxide (slaked lime) does it have a disinfecting effect. If quicklime powder is spread dry inside a barn, the dust will enter the respiratory tract of livestock and poultry, and after absorbing moisture in the respiratory tract it also becomes slaked lime. At this point its strong alkalinity not only fails to disinfect but also corrodes the respiratory mucosa, directly harming the health of livestock and poultry and causing respiratory diseases.
3. Do not spread quicklime powder directly and dry inside a barn for disinfection. This is because quicklime reacts with water and releases a large amount of heat, and the calcium hydroxide produced is corrosive, causing the hooves to become dry and crack. The quicklime dust will enter the respiratory tract of livestock and poultry, and after absorbing moisture in the respiratory tract it also becomes slaked lime. At this point its strong alkalinity not only fails to disinfect but also corrodes the respiratory mucosa, directly harming the health of livestock and poultry and causing respiratory diseases.
4. Quicklime is best bought and used fresh, and is not suitable for long-term storage. If quicklime is stored improperly, it will absorb moisture from the air and form slaked lime. Over time, the slaked lime will react chemically with carbon dioxide in the air to form calcium carbonate, which no longer has hydroxide ions and has lost its strong alkalinity, thus completely losing its bactericidal and disinfecting effect and greatly reducing the disinfection effect. Therefore, it should be purchased in an appropriate amount according to actual conditions and is not suitable for long-term storage.
