Can quicklime be sterilized? Can hydrated lime be disinfected and sterilized?

When the protein encounters a strong alkali, strong acid, high temperature, and heavy metal ions, it will be denatured, and the protein will lose its biological activity, and the quicklime will react with water to release a large amount of heat, and the formation of a strong alkali can make the protein of the bacteria inactive and thus play a role in sterilization.

Limestone is burned at high temperature, and calcium oxide is formed after losing carbon dioxide, which is crushed to become lime powder that can be used for sterilization and disinfection. Lumpy calcium oxide and its crushed powdered calcium oxide are collectively referred to as quicklime and are often referred to as lime for short. The disinfection and sterilization of lime is carried out with the help of the alkaline effect of lime aqueous solution.

Most of the lime can play a role in disinfection and sterilization, lime can produce a lot of heat when it encounters water, and can also generate a strong alkali, so that the protein in the bacteria is inactive, so that it can play a role in sterilization. It can be used for the disinfection of the environment, ground, enclosures, sewage ditches, feces, etc., and masks can be worn when applying lime powder for disinfection, which can avoid respiratory tract damage caused by lime powder inhalation, and lime powder should be placed in a dry and cool place to avoid moisture loss of effect.

Hydrated lime can be disinfected and sterilized. Hydrated lime is a white powdery solid, alkaline, with very strong hygroscopicity, can kill a variety of pathogenic bacteria, generally used for disinfection of walls, floors, septic tanks and sewage ditches.

Hydrated lime is a white powdery powder solid at room temperature, after adding water, it is two layers, the upper layer of clear aqueous solution is commonly known as clear lime water, and the lower layer is called lime milk composed of suspension.

If hydrated lime is exposed to the air for too long, it will chemically react with carbon dioxide in the air to form calcium carbonate.

Hydrated lime can be used to prepare bleaching powder, disinfectant, antacid, astringent, hard water softener, soil acid prevention agent, depilatory, buffer, neutralizing agent, curing agent, etc.

Lime powder can be sterilized. Lime powder is the product of limestone after high temperature burning and crushing, this kind of thing can be used for disinfection, but it needs to use water to play a role, lime powder in a dry state, and has no disinfection and sterilization effect. Only when a wet object is touched can it have a disinfectant effect.

Precautions for using lime powder:

Quicklime must be prepared and used, if it is placed for a long time, it will deteriorate and lose its sterilization and disinfection effect; If there are impurities in lime, it may burn, so be sure to buy lime powder from a professional manufacturer when buying it.

Lime powder will only have the effect of disinfection after encountering water, and it will be sprinkled directly on the dry ground, and there is no disinfection effect.

When disinfecting with quicklime, the disinfection site should be disposed of once, which can prevent contamination.

Generally speaking, with 5%-10% lime emulsion, there is a good disinfection effect. If the dosage is relatively large and the concentration is relatively high, the effect is not very good.

It is best to choose quicklime with less impurities, no agglomeration, and good purity. The better quality quicklime is all white, and there is white powder on the surface, and the poorer quality quicklime is often light gray or light yellow because it contains impurities.

Quicklime, also known as calcium oxide, is a white lump or powder, which produces heat and forms calcium hydroxide after adding water, which is strongly alkaline. This product can kill a variety of pathogenic bacteria, but it is ineffective for spores, and 20% lime milk solution is commonly used for disinfection of the environment, enclosures, floors, bedding, feces and sewage ditches. Quicklime should be dried and stored to avoid deliquescent failure; Lime milk should be used and prepared immediately, and it is best to use it up on the same day.

Is it OK to disinfect the reservoir and throw it whole into the water?

Quicklime disinfection needs to be mixed with water, mature lime water to have a disinfection effect. You can also sprinkle water on the ground and then sprinkle lime.

1. The direct use of quicklime has no sterilization and disinfection effect, and it is necessary to react the quicklime water with water for a period of time to produce mature lime water, which will have a certain sterilization effect.

2. You can also spray a certain amount of water on the ground, and then sprinkle lime powder on the water, which not only has a good sterilization effect, but also will not form a large amount of dust in the pig house.

Lime disinfection method:

1. Generally, after the pigs in the pigsty are slaughtered, the ground and wall are rinsed, and then the purchased quicklime is mixed with water to make 20% lime milk, and painted on the wall and ground of the pigsty, especially the gaps and corners, must be carefully painted, do not leave dead corners.

2. Some farmers directly sprinkle hydrated lime on the ground in the pigsty, which can easily lead to pig burns and cross-paw burns, and if the pigs eat the food on the ground, it will lead to burns to the mouth and digestive tract. Secondly, when spreading, lime dust will cause lime dust to fly everywhere, which is easy to be inhaled into the respiratory tract by pigs, which will cause symptoms such as coughing and sneezing.

3. In general, the wall of the Orchid House of the farm, use 1 liter of 10% lime milk brush about 3 times per square meter, and use fresh hydrated lime powder to sprinkle on the ground, sewage ditch, damp road and manure tank in the foraging and habitat of the farm. Because the cement floor is too dry, the effect of lime powder is not good.

When the lime is disinfected, you can add some nutrients inside, and it also needs to be evenly sprinkled on the roots, and it should be sprinkled less when spraying each time, but you must pay attention to using it 3 or 5 times a week.

You can dilute it with lime and water, and then pour it around the place to be disinfected, and you're good to go.

First of all, we should choose some lime disinfection with good effect, and we should also pay attention to the proportion of blending, and also pay attention to the method of use.

We can directly sprinkle lime on the place that needs to be disinfected, so that it can play a role in disinfection, in fact, it is also very simple.

No. Quicklime is a commonly used desiccant to remove water vapor by chemical absorption, and is also used for steel, pesticides, medicines, desiccant, tanning and alcohol dehydration. It is especially suitable for puffed food, shiitake mushrooms, fungus and other local products, as well as products in instrumentation, medicine, clothing, electronic telecommunications, leather, textile and other industries.

Lime and limestone are used in large quantities as building materials and are also important raw materials for many industries. Limestone can be processed directly into stone and fired into quicklime. Lime has quicklime and hydrated lime.

The main component of quicklime is CAO, which is generally lumpy, pure white, and light gray or light yellow when containing impurities.

Quicklime absorbs moisture or adds water to become slaked lime, which is also called slaked lime, and its main component is Ca(OH)2. Hydrated lime is blended into lime slurry, lime paste, lime mortar, etc., which is used as coating materials and brick and tile adhesives. Soda ash is prepared from limestone, salt, ammonia and other raw materials through a multi-step reaction (Solvay method).

Caustic soda is made by the reaction of slaked lime and soda ash (causticizing method).
