Application of foaming surfactants in disinfectants

Application of foaming surfactants in disinfectants
‍With the rapid and intensive development of the farming industry, farmers have reaped considerable profits, but since the emergence of African swine fever in 2018, the rampant epidemic has caused serious losses to the production of many farmers; foot-and-mouth disease, swine dengue, and blue ear are also endless, and in the context of multiple epidemics superimposed on the impact of the environment, the biosecurity of the breeding environment has become more important.

Taking pig breeding farms as an example, a hygienic breeding environment can directly affect the genuine farrowing rate of the next batch of piglets. Incomplete disinfection of farrowing beds can cause bacterial and viral diseases such as diarrhea in piglets after farrowing, which can lead to low piglet survival rate and substandard weaning weight, and only thorough disinfection of farrowing beds can have efficient disinfection effect. Disinfecting after rushing, the ground and the limit fence are wet, using conventional disinfectant spray, disinfectant and wet field “fused together”, disinfection can not achieve the “visualization” effect, dead ends can not be seen, not eliminated in place, out of the “invisible” disinfectant. Out of the “invisible” disinfectant solution, disinfection has become haphazard. The result is that although the amount of disinfectant is large, but the disinfection will soon be “zero”.

Normal Disinfection
Foaming agent solves this problem for us. After disinfectant is added to the foaming agent, a special foaming gun is used for disinfection to achieve the effect of “visualization”, and it is no longer a “blind” disinfection. After adding the foaming agent, the wet surface has a layer of “white” after disinfection, and the area that has been sprayed with disinfectant can be clearly seen. This type of foam disinfection has been accepted and used by more and more farms.
Effectiveness of disinfectants with foam additives for pig disinfection
The main ingredient of foam additives is surfactant, which is an important product of fine chemical industry and enjoys the name of “industrial monosodium glutamate”. Surfactant is a substance that can make the surface tension of the target solution decrease significantly, it has fixed hydrophilic and lipophilic groups, and it can be arranged directionally on the surface of the solution. It reduces the surface tension of water by adsorbing at the interface of gas and liquid phases, and also reduces the interfacial tension of oil and water by adsorbing between liquid interfaces. It has a wide range of applications and many functions, such as solubilizing, thickening, emulsifying, wetting, defoaming, washing and decontaminating, dispersing, sterilizing and disinfecting, antistatic, softening and smoothing.

Surfactant decontamination principle
Foaming is one of the important functions of surfactants. Foaming surfactants can reduce the surface tension of water and surround the air by double electron layer arrangement on the surface of liquid film to form bubbles, and then the single bubbles form foam. Excellent foaming agent is characterized by strong foaming power, fine foam and good foam stability.

Three elements of effective disinfection: effective disinfectant, effective concentration, and sufficient contact; while ensuring the quality of the disinfectant, the use of disinfectant formulated with foaming additives and disinfected with the help of a special foaming gun increases the contact time between the disinfectant and the target interface and the pathogenic microorganisms, which allows a more efficient and thorough disinfection to be achieved.
Main factors affecting the disinfection effect
Implementation of foam disinfection
The disinfectant is in full contact with the bars under the joint action of the foam additives (developed by Techhonda).
The pig house is disinfected with foam for 18-24h after rinsing and then turn the pigs, which makes the pig house have a layer of “sense of security”, and the disinfection is more trouble-saving, worry-saving, quantity-saving, and the health of the pigs is guaranteed accordingly; it is recommended to disinfect twice, the first time after rinsing and the second time after the first disinfection dries, and the interval between the two disinfections is 18-24h. The interval between the two sterilizations is 18-24h.
New farms in the introduction of breeding before the disinfection of the building, with foaming agent, so that disinfection “visible”, it is recommended to carry out two disinfection, disinfection time interval can be 12-24h.
