How many degrees of caustic soda disinfection did the vehicle undergo before leaving the factory?

100 lb of water accounts for 98% of the solution, so the caustic soda solution with a total weight of100 \ \ 98% kg >: 2% (100 \ \ 98%) × 2% is a good caustic soda disinfectant. Its 2% ~ 4% solution can kill bacteria and viruses, 10% solution can kill mycobacterium tuberculosis within 24 hours, and 30% solution can kill anthrax spores within 10 minutes. Therefore, caustic soda is often used to disinfect infectious diseases such as pullorum disease, chicken plague, duck plague, cholera, avian influenza, swine fever, erysipelas, bovine tuberculosis, brucellosis and foot-and-mouth disease. Generally, 2% ~ 4% disinfectant is used for wooden utensils, livestock and poultry such as farms, meat processing and other floors, houses, transport vehicles and so on. Solution heating can improve disinfection effect, and adding 10% salt can improve spore killing effect.

Attention should be paid to the use of caustic soda disinfection: if the skin and organs burned by caustic soda are not used for livestock, they should be disinfected, and the barns should be disinfected; Disinfection operators should pay attention to self-protection to avoid scalding the skin. Caustic soda has corrosive effect on textiles, and products such as aluminum products cannot be used for drug disinfection. After transporting livestock vehicles and boats, disinfect them with caustic soda solution for 6 ~ 12 hours, and then thoroughly clean the disinfectant to prevent corrosion damage.
