How much is quicklime per ton? How to correctly use quicklime for disinfection in aquaculture?

Quicklime, the main component of calcium oxide, all natural rocks with calcium carbonate as the main component, such as limestone, chalk, dolomite limestone, etc., can be used to produce lime. How much does quicklime cost per ton? How to use quicklime correctly for disinfection? From Changsha building materials boss Mr. Li learned that the price of quicklime powder is about 200-500, mainly as what use, calcium content, molybdenum number requirements.

How to use quicklime correctly for disinfection?

Quicklime is convenient in source, affordable in price, easy to buy, has the characteristics of strong disinfection power, is a pollution-free disinfectant, and is loved by the majority of farmers. However, due to improper use by many farmers, the purpose of disinfection and sterilization has not been truly achieved. Therefore, how to correctly use quicklime for disinfection should pay attention to the following points.

1, quicklime powder disinfection correct method. Disinfection of livestock and poultry farms: quicklime is mixed with water to prepare 10%~20% lime milk, sprayed at a dosage of 2~6 liters/square meter, which can disinfect roads, enclosure walls, floors, ceilings, pens, etc. With quicklime 1 kg, add water 350 ml, made of hydrated lime powder spread, can be wet ground, septic tank and sewage ditch disinfection. At the gate of livestock and poultry farm, wet straw bags and wet sacks soaked with 20% lime milk can be placed, replaced once every 3 days, and soles and wheels can be disinfected.

2. Do not sprinkle quicklime powder directly on dry ground for disinfection. Because quicklime cannot be directly disinfected, its main component is calcium oxide, and only calcium hydroxide (hydrated lime) formed after adding water has the effect of disinfection. If quicklime powder is sprinkled in the pen, the dust will enter the respiratory tract of livestock and poultry, absorb the moisture in the respiratory tract, and also become hydrated lime. At this time, the strong alkalinity will not only not disinfect, but also corrode the respiratory mucosa, directly endanger the health of livestock and poultry, and cause respiratory diseases.

3. Do not sprinkle quicklime powder directly into the enclosure for disinfection. Because quicklime reacts with water to release a lot of heat and the calcium hydroxide generated is corrosive, it causes the hoof to dry and crack. Quicklime dust will enter the respiratory tract of livestock and poultry, absorb moisture in the respiratory tract, and become hydrated lime. At this time, the strong alkalinity will not only not disinfect, but also corrode the respiratory mucosa, directly endanger the health of livestock and poultry, and cause respiratory diseases.

4, quicklime is best to buy now, should not be stored for a long time. If the quicklime is not properly stored, it will absorb the moisture of the air and form hydrated lime. Over time, the hydrated lime will react chemically with the carbon dioxide in the air to form calcium carbonate without hydroxide ions. If it loses its strong alkalinity, it will completely lose the efficacy of sterilization and disinfection, greatly reducing the disinfection effect. Therefore, according to the actual situation, appropriate purchase, not long-term preservation.
