According to preferred embodiment of the present invention, the mixed final viscosity of foregoing is 50-8000cps, and preferable final viscosity is 100-4000cps, and the best final viscosity of mixing the back composition is 150-2000cps.
Embodiment
The invention provides a kind of algaecide composition that contains water soluble polymer and preparation method thereof, wherein said composition can improve removing algae usefulness attached to the algae of body surface, and reduce when using algicide other biological toxicity beyond the algae, further can reduce the algicide use cost.The present invention is the extra water soluble polymer that adds in existing algicide product, this water soluble polymer, be meant that mainly molecular weight is big, and the polymer substance that a large amount of hydrophilic radicals are arranged in the molecule, preferable example, including but not limited to: a kind or above-mentioned mixture more than a kind in polyvinyl alcohol, polyacrylamide, polyethylene glycol oxide, polyvinyl pyrrolidone, water soluble starch derivative, water-soluble cellulose derivative and the xanthans (Xanthangum); Water soluble polymer with after the algicide of existing kind fully mixes, and is fully dissolved the back with water and forms a mixture, said mixture is given drying, and the algicide mixture of gained is made medicament.
Be energy detail knowledge technical characterictic of the present invention and practical effect, and can implement, further, be described in detail as follows with following preferred embodiment according to the content of specification:
Embodiment 1: the preparation of solid-state algaecide composition
In algaecide powder, for example, copper-containing compound (copper sulphate, copper chloride, Schweinfurt green etc.), zinc compound, bleaching powder etc. add water soluble polymer, and this water soluble polymer can be powdery.The kind of this water soluble polymer includes but not limited to, a kind or above-mentioned mixture more than a kind in polyvinyl alcohol, polyacrylamide, polyethylene glycol oxide, polyvinyl pyrrolidone, water soluble starch derivative, water-soluble cellulose derivative and the xanthans (Xanthangum).Algaecide powder is fully mixed with the pulverulent water-soluble polymer, or algicide dissolved in water with above-mentioned water soluble polymer mix, under the situation that does not influence both character, give drying, wherein drying mode can be atomized drying, freeze drying etc., and gained powder after the drying further can be made sheet, graininess or ingot shape medicament, wherein, be preferably powdery or graininess.
In preferred embodiment of the present invention, the water soluble polymer that is added and the ratio of algicide can be 10%-99.99%:90%-0.01% (W/W), preferred proportion is 30%-99.99%:70%-0.01% (W/W), and optimal proportion is 50%-99.99%:50%-0.01% (W/W); Wherein, the contained water soluble polymer content of the present invention is high more, and the disintegration of composition or dissolving are slow more, and low more then composition disintegration of water soluble polymer content or dissolving are fast more.
Embodiment 2: the preparation of liquid algaecide composition
In aqueous algicide, for example: copper-containing compound (copper sulphate, copper chloride, Schweinfurt green etc.), zinc compound, alkyldimethylbenzylammonium chloride (Benzalkonium Chloride) etc., add water soluble polymer, this water soluble polymer can be powdery.The kind of this water soluble polymer includes but not limited to, a kind or above-mentioned mixture more than a kind in polyvinyl alcohol, polyacrylamide, polyethylene glycol oxide, polyvinyl pyrrolidone, water soluble starch derivative, water-soluble cellulose derivative and the xanthans (Xanthangum).With the pulverulent water-soluble polymer water-soluble after, be modulated into a viscous solution, and mix with liquid algicide and to form a mixture; Preferably, the final viscosity of this mixture is 50-8000cps; More preferably, final viscosity is 100-4000cps; Best is that final viscosity is 150-2000cps.Since with a kind of water soluble polymer, the same concentrations different model, both viscositys also may differ several times, thus do not represent at this with component ratio, and represent with viscosity.In specific embodiments of the invention, the viscosity of water soluble polymer is high more, and then disintegration or dissolving are slow more, and low more then disintegration or dissolving are fast more.
Use two prepared algaecide compositions of embodiment of the present invention, can select the local dispenser of water body.Because the effect of water soluble polymer, the algicide that contains the water soluble polymer thing will be deposited on the body surface of desire effect, and formation contains glue (approaching) film of rendeing a service except that algae, medicine will temporarily be confined to launch to remove algae in glue (approaching) film and simultaneously and be renderd a service, after after a while, meeting disintegration of glue (approaching) film or decomposition are also finished except that the algae effect simultaneously, this glue (approaching) film and remove the algae composition and will be dissolved in whole water bodys, and form extremely low concentration.
When utilizing algaecide composition in the embodiment of the invention to the local dispenser of water body, when algicide was reached except that algae usefulness, the algicide that residue is dissolved in the water became split pole low, and it is biological and produce poisoning therefore needn't to worry to injure beyond the algae other.
Owing to can select the local dispenser of water body, so dosage reduces relatively, and consumption is few, and use cost also can descend relatively, and the safety of use also will significantly improve.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, have in the technical field under any and know the knowledgeable usually, if in the scope that does not break away from technical characterictic that the present invention carries, the equivalent embodiment that utilizes disclosed technology contents to do local change or modified, and do not break away from technical characterictic content of the present invention, all still belong in the scope of the technology of the present invention feature.
