However, the use of chlorine gas for sterilization has many serious problems in application. The first is safety issues. Chlorine gas has a strong pungent odor and strong corrosiveness, is highly toxic, and is easy to leak. Once chlorine gas leaks, it will cause harm to the surrounding environment and personnel. great damage and harm
The second is the large amount of equipment maintenance. There must be two people on duty for each shift of chlorination equip

Abstract
The invention discloses a non-oxidized seawater bactericide, which comprises the following components in part by weight: 30 to 80 parts of poly(hydroxypropyl) polyene polyamine, 10 to 30 parts of dodecyl triphenyl phosphorus chloride, 10 to 20 parts of dication quaternary ammonium salt and 5 to 10 parts of isopropanol. A method of a production process comprises the following steps of: adding the poly(hydroxypropyl) polyene polyamine and the isopropanol into a reaction kettle; slowly heating to 80 DEG C; stirring for 30 minutes; adding the dodecyl triphenyl phosphorus chloride; continuously stirring at the constant temperature of 80 DEG C for 30 minutes; adding the dication quaternary ammonium salt; stirring for 10 minutes; and standing and naturally cooling until material temperature is between 20 and 35 DEG C. The production process is simple, an operation process is simple and convenient, and safety performance is very high.
Description
technical field [0001] The invention belongs to fungicides, in particular to a non-oxidizing seawater fungicide and a preparation method thereof. Background technique [0002] In the Bohai Sea area, the seawater desalination supplementary water system and the generator set that uses seawater as circulating cooling water, the key problem is the adhesion and fouling of marine molluscs, especially the adhesion and fouling of "sea oysters". Sea oysters belong to hermaphroditic crustaceans. Its carapace forms a shell and is fixed on the substrate by mucus, and the substrate is also fixed on rocks or ship walls and pipe walls by mucus. This kind of mucus is calcite in protein, which is similar to colloid. According to analysis, it is composed of 24 kinds of amino acids and amino sugars. It won't be washed away either. Sea oysters are hermaphrodites, live in groups, and have a very strong reproductive capacity. When sea oysters find a relatively suitable place to live, they quick...
