Problems solved by technology

However, both of these two disinfectants have corresponding disadvantages. Dibromohydantoin is highly corrosive and limited in low-temperature environments, and the stability of o-phthalaldehyde disinfectants is relatively poor.

Embodiment 1

[0029] The best compound disinfectant formula is 200 mg / L dibromohydantoin and 50 mg / L o-phthalaldehyde compound, with Staphylococcus aureus as the killing object, with the previously screened concentration (dibromohydantoin concentration 400mg / L, phthalaldehyde concentration 100mg / L) as the basis, each set as 100%, and the two disinfectants are based on DBDMH:OPA=1:9, 2:8, 3:7, 4:6, 5:5 The proportions are compatible with each other. The killing effect is shown in Table 2. From Table 2, it can be seen that when the compatibility ratio of dibromohydantoin and o-phthalaldehyde is 5:5, that is, when 200mg / L dibromohydantoin and 50mg / L o-phthalaldehyde, the compatibility of disinfectant sterilization The value reached 5.67. Compared with dibromohydantoin and o-phthalaldehyde (the logarithmic value of sterilization is about 4), the bactericidal effect is significantly improved, and the compound disinfectant has good applicability.

Abstract

The invention relates to a dibromohydantoin and ortho-phthalaldehyde-based novel compound disinfectant formula, and belongs to the technical field of bioengineering. The dibromohydantoin disinfectant has the advantages of being high in efficiency and broad in spectrum, but is strong in metal corrosivity and limited in use in low-temperature environment; the ortho-phthalaldehyde disinfectant has the advantages of being weak in toxic and side effects and relatively low in metal corrosivity. Therefore, the compound disinfectant is capable of improving the disadvantages of a single disinfectant through matching the two disinfectants. The compound disinfectant formula is obtained by the steps of screening the matching concentrations of the two disinfectants and verifying the metal corrosivity experiments. The dibromohydantoin and ortho-phthalaldehyde-based novel compound disinfectant can be used for container disinfection and sterilization in port transportation, is capable of effectively reducing the corrosivity to the containers, and has a certain application value.

Description

technical field [0001] The invention relates to a novel compound binary disinfectant formula based on dibromohydantoin and o-phthalaldehyde. It belongs to the technical field of bioengineering. The invention also provides the bactericidal effect test of the disinfectant. Background technique [0002] With the steady increase in the share of China's import and export trade in the world, in 2013, China's container throughput reached 175 million TEU (standard containers), ranking first in the world, and China has developed into a global container shipping center and container manufacturing center. Among the major port cities in China, Shanghai Port is at the top of the list with an absolute advantage of 33.62 million TEU (standard containers), and the gap between the total container volume of Shenzhen Port and Shenzhen Port has further widened to 10.33 million TEU. [0003] However, there are many shortcomings in container port transportation. Due to the periodicity, sealing ...
