Description
Technical field
The present invention relates to sym-closene, is a kind of sym-closene effervescent tablet and preparation method thereof.
Background technology
Sym-closene is a kind of extremely strong oxidant and chlorinating agent, has the disinfective action of efficient, wide spectrum, safety, and bacterium, virus, fungi, gemma etc. are all had killing action, is widely used in the sterilization in a plurality of fields such as environment, drinking-water, animal feeding.Because there are deficiencies such as transportation inconvenience, permanent chlorine weak effect in the powder of sym-closene, so the monolithic of sym-closene and compound sheet are widely used.Yet, in use find, though the available chlorine content of folk prescription sheet up to 90%, its pH value is lower, solvability is little, the dissolution velocity in water is slower, in order to address the above problem, those skilled in the art provide the compound sheet.Disclosed compound sheet generally adopts raw materials such as sym-closene, sodium bicarbonate and organic acid to process, but its effervesce effect is not good enough, and it is serious to deposit in the process decomposition of product, and the permanent chlorine effect in the key technical indexes is relatively poor, influences the Disinfection Effect of product.
Summary of the invention
The objective of the invention is, a kind of sym-closene effervescent tablet and preparation method thereof is provided, make it solve the deficiency of prior art, effervesce and permanent chlorine effect are all improved a lot.
The present invention is for realizing above-mentioned purpose; Realize through following technical scheme: the sym-closene effervescent tablet comprises following weight percentages: sym-closene 46-50%, sodium carbonate 18-23%, cyanuric acid 14-17%, boric acid 2-5%, Sodium Benzoate 5-8%, polyvinylpyrrolidone 1-2%, lauryl sodium sulfate 0.2%, anhydrous citric acid 1.5% and sodium carboxymethylcellulose 0.3%.
Described sym-closene effervescent tablet comprises following weight percentages: sym-closene 50%, sodium carbonate 20%, cyanuric acid 14%, boric acid 5%, Sodium Benzoate 7%, polyvinylpyrrolidone 2%, lauryl sodium sulfate 0.2%, anhydrous citric acid 1.5% and sodium carboxymethylcellulose 0.3%.
Described sym-closene effervescent tablet comprises following weight percentages: sym-closene 47%, sodium carbonate 21%, cyanuric acid 15%, boric acid 5%, Sodium Benzoate 8%, polyvinylpyrrolidone 2%, lauryl sodium sulfate 0.2%, anhydrous citric acid 1.5% and sodium carboxymethylcellulose 0.3%.
Described sym-closene effervescent tablet comprises following weight percentages: sym-closene 50%, sodium carbonate 18%, cyanuric acid 17%, boric acid 5%, Sodium Benzoate 7%, polyvinylpyrrolidone 1%, lauryl sodium sulfate 0.2%, anhydrous citric acid 1.5% and sodium carboxymethylcellulose 0.3%.
The preparation method of described sym-closene effervescent tablet comprises the steps:
1. sieve raw material: get sym-closene 46-50%, sodium carbonate 18-23%, cyanuric acid 14-17% and boric acid 2-5% and sieve respectively, the particle that will stick to each other separates, and bulky grain or lump are rejected;
2. the raw material of step in 1. dropped into and be mixed in the mixer evenly;
3. the homogeneous material of step in 2. inserted crusher for crushing to the 100-150 order;
4. get 200 purpose Sodium Benzoate 5-8% and insert in the mixture of step in 3., mixing in mixer obtains the granulation standby material;
5. the granulation standby material is inserted comminutor and carry out granulation, obtain granular standby material;
6. in granular standby material, add polyvinylpyrrolidone 1-2%, lauryl sodium sulfate 0.2%, anhydrous citric acid 1.5% and sodium carboxymethylcellulose 0.3%, subsequent use behind the mixing;
7. obtain the sym-closene effervescent tablet after the material of step in 6. being adopted the tablet press machine compacting.
Effervescent tablet of the present invention is in order to solve the not good enough problem of permanent chlorine in the prior art; Selected cyanuric acid for use; The adding of cyanuric acid can be stablized the main component of whole component; After effervescent tablet is water-soluble, can make sym-closene become sodium dichloro cyanurate rapidly, thereby permanent chlorine effect is significantly improved.Simultaneously,, have stability preferably,, effervescent tablet can be dissolved fast so it can improve the effervesce speed of effervescent tablet because cyanuric acid is a kind of organic acid.
The sodium carbonate that adds in the raw material of effervescent tablet according to the invention because its alkalescence is stronger, makes the chlorinity in the effervescent tablet higher, and can increase the effervesce effect; Boric acid can make the strong oxidizing property of sym-closene tend towards stability, and is difficult for decomposing, and increases the safety in production, storage and the transportation, and can increase stripping result; Lauryl sodium sulfate is used to increase the molten water-based of effervescent tablet; Anhydrous citric acid is used for anti-oxidant, further increases the stability of effervescent tablet; Sodium Benzoate is used to increase stripping result.Make effervescent tablet further improve the availability of sym-closene after the whole component combination of effervescent tablet of the present invention; Increased substantially permanent chlorine effect, can be in 54 ℃ of isoperibols 14 days, available chlorine content reaches about 44%; Rate of descent is about 11%, has improved sterilizing ability.Effervescent tablet of the present invention also has advantage cheap for manufacturing cost etc.
