Description

A kind of aquaculture disinfectant powder and preparation method thereof

Technical field

The present invention relates to a kind of aquaculture disinfectant powder and production method thereof, specifically it can be used as the product use of aquaculture industry water body disinfection, belongs to technical field of aquaculture.

Background technology

Present aquaculture industry sterile products is many to be main component with single chemical raw material, though can guarantee Disinfection Effect, may cause secondary harm to water body and aquatic animal after the sterilization.

For example the most frequently used disinfectant mostly is the compound that contains active chlorine.This type of chlorine-containing disinfectant because raw material are easy to get, prepares easily, low price, and bactericidal action is reliable, therefore is used widely.But this type of disinfectant has penetrating odor, and skin is had stimulation, is corrosive, poor stability, and the bactericidal action duration is short, and aquatic animal is had certain cumulative toxicity.

Chlorine dioxide is the new disinfectant of development in recent years; Be a kind of wide-spectrum bactericide, but many animal test results have shown carcinogenic, the teratogenesis shape of long-term use meeting, for example chlorine dioxide are taken in the small white mouse stomach; Chlorine dioxide is absorbed with chlorion and chlorine dioxide form; Chlorine dioxide can oxygenated haemoglobin, makes it to be converted into the ferrihemoglobin of non-pigment function, makes animal that methemoglobinemia take place.The record of hemolytic anemia occurs after also having oral chlorine dioxide in addition, and find to produce the needed chlorine dioxide dosages of hemolytic anemia and want much less than producing the required chlorine dioxide dosages of methemoglobinemia.When containing chlorine dioxide 100mg/l in the experiment proof drinking-water; Can be observed tangible hemolytic anemia phenomenon in the small white mouse body, and contain chlorine dioxide 50mg/l in the drinking-water, even when being lower than 10mg/l; Though tangible clinical symptoms do not occur, glutathione obviously reduces in the body.

Peroxide also is one type and uses disinfection composition more widely; Mainly contain hydrogen peroxide (hydrogen peroxide solution), Peracetic acid, Peroxycaprylic acid etc.; Be exactly hydrogen peroxide wherein for what the people was familiar with; This close special education in 1864 is awarded and has just been found that hydrogen peroxide has bactericidal action, and sterilizing ability is near mercury chloride.Hydrogen peroxide can be killed the most obstinate anthrax-bacilus spore when concentration 100mg/l, and clostridium is also had good killing action, and its highly-water-soluble makes it be easy to clean.But its limited advantage has unfortunately been offset by some serious defectives: its good bactericidal property of active concentration that only reaches qualification could be guaranteed.The influence of temperature, pH value and heavy metal can both make it lose activity, and it can produce incomplete chemical reaction with most of materials, like ethanol, acetone, acetaldehyde, metal ion, sodium hydroxide etc.In addition, peroxide is attacked skin and is arrived subcutaneus adipose tissue and causes the gangrenosis that is difficult to cure, and it caused tumour in some zooperies.So hydrogen peroxide as the disadvantage of disinfectant be poor stability, the sterilization duration is short, sterilization speed is slow, surface tension is big, price is high.

Neutral quarternary ammonium salt compound belongs to the category of low toxicity, and it is used for the mucous membrane sterilization for many years, and according to " Switzerland's noxious material method ", its oral acute toxicity intensity is about 4000mg/kg, so it is a low toxicity.The gathering of its active tension cell membrane has better action, but some fungies and pathogenic gemma are not had effect.

C5H6Br2N2O2 (1,3-two bromo-5,5-dimethyl hydantoin) is in recent years by the disinfection composition of more and more widely using; Its killing action to microorganism is effectively reliable, belongs to high effect disinfectants, but kill bacteria, fungi, virus and gemma; Disinfection efficiency than chlorine-containing agent is high, and particularly its acute toxicity is much lower more than chlorinated product, does not produce residual toxicity after the use; This is because C5H6Br2N2O2 discharges in water after hypobromous acid and the free active bromine; Remaining 5.5 1 dimethyl hydantoins are nitrogen and carbonic acid gas by light, oxygen and microbial decomposition, not because of the residual contamination environment under field conditions (factors).But its solvability in water is lower, and dissolution velocity is slow, has caused C5H6Br2N2O2 in order in actual application, to reach Disinfection Effect, and has had to increase consumption, has caused the use cost rising, and influence is promoted the use of.

Summary of the invention

The objective of the invention is to overcome C5H6Br2N2O2 poor solubility, the slow deficiency of dissolution velocity, through synergy, provide a kind of have instant, be prone to dissolve, the aquaculture disinfectant powder and the production methods thereof of characteristics such as cost is low, safety and environmental protection.

According to technical scheme provided by the invention, a kind of aquaculture disinfectant powder, recipe ingredient is following by weight: C5H6Br2N2O2 20-50 part, hexa 10-20 part, sodium carbonate 20-30 part and sodium bicarbonate 20-30 part;

Sodium carbonate, sodium bicarbonate, C5H6Br2N2O2, hexa are crossed 80 mesh sieves successively, join successively then in the powder stirrer, after stirring, leave standstill, detecting, pour into and promptly obtain finished product aquaculture disinfectant powder in the sealed plastic bag.

A kind of preparation method of aquaculture disinfectant powder, step is following by weight:

Get 20-30 part sodium carbonate, 20-30 part sodium bicarbonate, 20-50 part C5H6Br2N2O2 and 10-20 part hexa and cross 80 mesh sieves successively, join in the powder stirrer successively; Start powder stirrer, 20-30 ℃ of normal pressure stirred 1-2 hour 10 rev/mins of agitator rotating speeds down;

The mixture that stirring is obtained left standstill 10-14 hour, after the detection active constituent content is qualified, poured in the sealed plastic bag, promptly obtained product aquaculture disinfectant powder.

The present invention has following advantage: this prescription has overcome C5H6Br2N2O2 poor solubility, the slow deficiency of dissolution velocity, through synergy, provide a kind of have instant, be prone to dissolve, cost is low, the aquaculture disinfectant powder of safety and environmental protection.Product of the present invention not only dissolution velocity is fast, can reduce use cost, can also produce good economic benefit and environmental benefit; It fills a prescription unique, and effect is remarkable, does not see bibliographical information both at home and abroad, has novelty and good popularizing application prospect.
