Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention firstly provides an environment-friendly novel disinfectant and bactericide, which comprises the following raw materials in parts by mass: potassium monopersulfate complex salt: 75-80 parts; sodium chloride: 2-3; citric acid: 5-10; succinic acid: 3-5; 5-10 parts of a traditional Chinese medicine preparation.
In the raw material components, the traditional Chinese medicine preparation is folium artemisiae argyi essential oil.
The environment-friendly novel disinfectant and bactericide provided by the invention selects potassium monopersulfate composite salt as a main component, is added with Chinese herbal preparation namely folium artemisiae argyi essential oil, is compounded with sodium chloride, citric acid and succinic acid, so that the raw materials can be controllably distributed on the cell wall of a microorganism, the permeability of a cell membrane can be changed and ruptured by the oxidation of nascent oxygen (O) and free hydroxyl (OH), and the normal function of the cell membrane is lost, and meanwhile, the chlorination and acidification effects of hypochlorous acid (HCLO) and hydrogen peroxide (H2O2) prevent the synthesis of protein of pathogenic microorganism cells by inhibiting the enzyme in the cells of the pathogenic microorganism, so that the cells are decomposed and killed, and finally the cells are killed.
Potassium monopersulfate is used as an environment-friendly disinfectant, has strong oxidizing power, has a killing effect on various microorganisms, and has the advantages of wide sterilization spectrum, strong sterilization effect, reliable sterilization effect, no residual pollutants, safety and high efficiency.
The specific mechanism is as follows: the potassium monopersulfate has chain reaction in water to produce nascent oxygen (O), hypochlorous acid (HClO), free hydroxyl (OH-), and hydrogen peroxide (H2O 2); the nascent oxygen (O) is very active and has very strong oxidizing capability, can denature proteins of bacteria and viruses, destroy the synthesis of genetic substances of the bacteria and the viruses, and change the permeability of cell membranes to break the cell membranes, thereby losing the normal functions of the cell membranes and achieving the aim of killing the bacteria, the fungi, the protozoa and the viruses; hypochlorous acid (HClO) and hydrogen peroxide (H2O2) have chlorination and acidification effects, and can inhibit enzymes in pathogenic microorganism cells and prevent protein synthesis, so that the cells are decomposed and killed to achieve the effect of killing microorganisms; the nascent oxygen (O), the hypochlorous acid (HClO) and the free hydroxyl (OH-) can kill microorganisms simultaneously, and can play a role in synergistic sterilization to the maximum extent; meanwhile, the chloride released after killing the microorganisms is oxidized into hypochlorous acid and free hydroxyl by active oxygen of potassium hydrogen persulfate, and the action is performed for a long time; the potassium monopersulfate can quickly oxidize reduced-valence chloride ions into chlorine simple substances, chlorine is dissolved in water to generate hydrochloric acid and hypochlorous acid, and the chlorine and the potassium monopersulfate are used for sterilizing in a synergistic manner, so that toxic chloramines generated by combination of chlorine and organic matters are avoided.
Potassium monopersulfate can oxidize ferrous iron in water and the bottom of the pond into ferric iron, divalent manganese into manganese dioxide, nitrite into nitrate, hydrogen sulfide into sulfate, and form an oxidation surface layer at the bottom of the pond, so that toxic substances in the bottom mud can be effectively prevented from diffusing into the water under the condition of sufficient dissolved oxygen. The ammonia nitrogen in the water body consists of molecular ammonia and ionic ammonia, the oxidation reaction is carried out along with the increase of dissolved oxygen in the water body, the ionic ammonia is converted into nitrite, the nitrite is converted into nontoxic nitrate after being continuously oxidized, and the concentration of harmful substances such as the ammonia nitrogen, the nitrite, hydrogen sulfide, heavy metal ions and the like in the pond is effectively reduced, so that the aim of detoxification is fulfilled.
Preferably, the preparation method of the embodiment of the environment-friendly novel disinfectant and bactericide comprises the following steps:
(1) selecting raw materials of potassium monopersulfate composite salt, sodium chloride, citric acid and succinic acid according to parts by weight.
(2) The raw materials are fully mixed in a powder mixer to form a mixture A.
In the step, potassium monopersulfate composite salt powder and sodium chloride are compounded and mixed according to a ratio, and then are mixed with the citric acid and the succinic acid to form a mixture A.
(3) Weighing pure water and the mixture A according to the weight ratio of 10-20:1, then injecting the pure water into a high-speed disperser, and then slowly adding the mixture A; simultaneously, dropwise adding a certain amount of the traditional Chinese medicine preparation through a feeding device, uniformly stirring and dispersing for 80-120 minutes to prepare a thick mixed solution B;
in the step, after injecting pure water into the high-speed disperser, firstly rotating the high-speed disperser at the speed of 500 plus one 1000 rpm, slowly adding the mixture A, simultaneously slowly dripping the quantitative traditional Chinese medicine preparation at a constant speed, and uniformly stirring for 20-40min, and after the mixture A and the traditional Chinese medicine preparation are completely added, then rotating the high-speed disperser at the speed of 3000 plus one 3500 rpm and stirring for 60-80 min.
The reason is that the citric acid and the succinic acid are mixed with the pure water for a certain time and have the requirement of viscosity, and in addition, the folium artemisiae argyi essential oil which is a traditional Chinese medicine preparation has low solubility in water and needs to be slowly dripped at a uniform speed so as to dissolve various raw material components. The mixture A and the Chinese medicinal preparation folium Artemisiae Argyi essential oil are gradually and slowly added while stirring at low speed to facilitate the dissolution of the Chinese medicinal preparation folium Artemisiae Argyi essential oil and the mixture A in water. After the mixture A and the Chinese medicinal preparation folium artemisiae argyi essential oil are completely added, the mixture A and the Chinese medicinal preparation folium artemisiae argyi essential oil can be uniformly dispersed to form suspension by high-speed stirring, so that the high-speed stirring is adopted in the subsequent step, and the raw materials can be fully and uniformly dispersed in water.
(4) Stirring and diluting the mixed solution B and the pure water according to the volume ratio of 1:100-1000 to prepare the novel liquid disinfectant.
In the step, the mixed liquid B is added with quantitative pure water, stirred and diluted, and then prepared into a finished product of the novel liquid disinfectant and bactericide by a filling machine.
The preparation method of the embodiment of the environment-friendly novel disinfectant and bactericide selects potassium monopersulfate composite salt as a main component, adds the traditional Chinese medicine preparation folium artemisiae argyi essential oil, and compounds sodium chloride, citric acid and succinic acid according to a certain sequence and proportion to prepare the environment-friendly novel disinfectant and bactericide.

3. High efficiency: the bactericidal performance is shown to be strong, long-acting and broad-spectrum, the bactericidal effect can be achieved under low concentration, and the bactericidal rate of the traditional medicament 1/10 reaches 99.9 percent, which is higher than that of the traditional medicament; the bactericide has strong killing effect on fungi, bacteria, viruses and spores, also has killing effect on legionella and also has stripping effect on green algae; active oxygen is released continuously, the effect is achieved within 15 minutes, and the long-acting sterilization is carried out within 72 hours.
4. The comprehensive use cost is low: because of small usage amount and long action time, the dosage is greatly reduced, the disinfection time interval is increased and the comprehensive cost is reduced in the general use process.
