Does caustic soda help with disinfection Does caustic soda help with disinfection

1. Caustic soda can be used to disinfect bacteria.

2. Caustic soda is a colorless and transparent crystal, which is characterized by being easy to fuse with water, and will release heat in the process of fusion. Strictly speaking, caustic soda is a relatively common strong alkali substance, and the disinfection principle is that it can hydrolyze the protein and nucleic acid of pathogenic bacteria, destroy the normal metabolic function of bacteria, and make bacteria die, and its bactericidal effect is strong, and can kill viruses.

Can be disinfected. Caustic soda is a very good disinfecting drug. Its 2% 4% solution kills propagating bacteria and viruses, 10% solution kills Mycobacterium tuberculosis within 24 hours, and 30% solution kills anthrax sore within 10 minutes.

Therefore, caustic soda is often used for the disinfection of infectious diseases such as chicken dysentery, chicken plague, duck plague, avian cholera, swine erysipelas, swine fever, cattle flu, tuberculosis, brucellosis, foot-and-mouth disease, etc.

Generally, a 2% and 4% solution is used to disinfect the ground, barns, wooden utensils, and livestock and poultry transportation vehicles of feedlots and meat plants. Its solution can be used after heating, which can improve the disinfection effect; The addition of 10% table salt can enhance the sporicidal effect.

Pay attention when using caustic soda disinfection:

Caustic soda has a burning effect on ** and organs, and cannot be used for animal body disinfection, and livestock and poultry should be driven out of the house during disinfection; Personnel who carry out disinfection operations should pay attention to self-protection to avoid burns**.

Caustic soda has a corrosive effect on textiles and aluminum products, and such supplies cannot be sterilized with this medicine. Cars and boats transporting livestock and poultry are disinfected with caustic soda solution for 6 hours and 12 hours, and then the disinfectant is thoroughly rinsed off with clean water to avoid corrosion and damage.

The disinfection effect of caustic soda is not affected by temperature. The dissolution of caustic soda with hot water only accelerates the dissolution, and does not change its chemical properties, and the disinfection effect is not affected. Add water to dilute or dissolve caustic soda, prepare 1% 2% caustic soda solution to spray disinfection, mainly used for the disinfection of livestock houses, vehicles, etc., and 50% solution is used for the corrosion of new horns of cattle and sheep.

Hot water melts faster, but it's not safe, it's easy to get hurt if you don't get it right, and it's safe to slow down cold water.

Quality. Sodium hydroxide is strongly alkaline and has strong hygroscopicity. Soluble in water, exothermic when dissolved, the aqueous solution is alkaline and has a greasy feeling; It is extremely corrosive and has a corrosive effect on fibers, glass, ceramics, etc.

Hydrogen is released by reacting with metal aluminum and zinc, non-metal boron and silicon; disproportionation reaction with halogens such as chlorine, bromine, iodine; It neutralizes with acids to form salt and water.

Alkaline water has no disinfecting effect.

But alkaline water has the following effects:

1. Neutralize the acid in the invert sugar syrup to prevent the sourness of the moon cake from affecting the taste and texture;

2. Control the speed of oil return and adjust the hardness of the crust;

3. Increase the alkalinity of the moon cake crust, which is conducive to the coloring of the moon cake, the higher the alkalinity, the easier the moon cake crust is to color;

4. The neutralization reaction between the water and the acid produces a certain amount of carbon dioxide gas, which promotes the moderate expansion of the moon cake and makes the taste of the moon cake crust more loose and not deformed.
