Can gypsum powder disinfect and kill insects

Quicklime transforms mature lime in the process of absorbing moisture.

Alkaline, the calcium produced by it can denature proteins.

Kills bacteria and fungi and has a deworming effect.

However, it is not possible to directly sprinkle quicklime on the ground to achieve the effect of repelling insects, if the quicklime powder is directly used.

Sprinkled on the dry ground, it will not have the desired disinfection effect, and will even cause harm to livestock and poultry, causing burns, cracks and even ulcers on the hooves.

When livestock and poultry exercise and feeding, lime foam enters the mouth and nose of livestock and poultry, causing burns to the mouth, digestive tract and respiratory tract, and causing coughing.

Sneezing, in severe cases, can also cause respiratory inflammation;

The correct way to use quicklime for disinfection and insecticide is:

1) Prepare 10 20 lime milk with fresh quicklime (whichever is not damp) to sterilize. 10. Lime milk preparation method and use is: take 1 kg of fresh lime and add 1 kg of water, let it mix and react, add 9 kg of water, let it precipitate after stirring, and take the supernatant (or remove the residue) can be used for spray disinfection of livestock (poultry) houses, floors and walls.

2) After livestock and poultry are slaughtered, 20% lime milk (take 1 kg of fresh lime and add 1 kg of water, let it mix and react, and then add 4 kg of water), paint the wall or ground of the stable for disinfection, and use 20% lime milk for livestock and poultry manure and carcasses.

3) At the entrance of the livestock and poultry farm, place wet straw bales and wet sack pieces soaked with 20% lime milk, and disinfect the soles and wheels.

So why quicklime can be used to kill insects, the principle is mainly that quicklime can absorb water and turn into quicklime, on the one hand, it can adjust the pH of the soil.

There can be a reason for the growth of plants; On the other hand, fungi and bacteria are proteins, and in the process of reacting quicklime with water to become mature lime, the calcium produced can denature the protein, never kill bacteria and fungi, and play a role in killing insects and prevention.

So gypsum powder.

It can kill insects, raise fish, and use gypsum powder, that is, quicklime, when breeding.

Gypsum powder can not be disinfected and insecticidal, it is used to fill an object, powder is generally disinfected, and quicklime powder is also calcium carbonate, which can disinfect and kill insects.

Gypsum powder has no disinfecting and insecticidal effect. For some insects that are afraid of dry powder, gypsum powder can interfere with its activity or cause death, such as slugs.

No, gypsum and lime are two different things, lime can disinfect and kill insects, gypsum cannot.

Gypsum powder can only replace lime powder for dehumidification, but it cannot play a sterilizing role.

Gypsum powder is an important industrial raw material. The color is usually white and colorless, and the colorless transparent crystals are called transparent gypsum, and sometimes they become gray, light yellow, light brown and other colors due to impurities. Streaks are white, transparent, vitreous luster, cleavage plane pearl luster, fibrous aggregate silk luster.

The cleavage is extremely complete, and medium, and the cleavage sheet is split into rhomboids with surface angles of 66 and 114. Brittle. Hardness.

There is a slight change in different directions. Relative density. Gypsum powder is one of the five major gel materials, which occupies an important position in the national economy and is widely used in many applications such as construction, building materials, industrial molds and art models, chemical industry and agriculture, food processing and medicine and cosmetology.

With the development of gypsum products industry, a variety of different uses of gypsum powder have also been promoted, especially in the building materials industry, with the continuous increase of high-rise buildings and the gradual deepening of the national wall reform work, gypsum powder has become a sought-after product in the building materials market.

I guess I should use quicklime powder.
