Abstract
The invention discloses a kind of BCDMH effervescent tablet, comprise following raw material composition according to this filler of parts by weight: BCDMH 1-40 part, cosolvent 1-25 part, effervescent agent 0.5-20 part, stabilizing agent 1-5 part, filler 20-96.5 part. The BCDMH effervescent tablet the present invention relates to can be dissolved in rapidly in water, reaches the needed concentration of sterilization; The BCDMH effervescent tablet good stability the present invention relates to, continues sterilizing ability strong; The BCDMH effervescent tablet sterilizing ability the present invention relates to is strong, and 200ppm can kill withered black gemma.
Description
Technical field
The present invention relates to sterilization field, be specifically related to a kind of instant BCDMH effervescent tablet and its preparation method and application.
Background technology
BCDMH is a kind of novel brominated disinfectant, can be used for Treatment of Industrial Water and mineral spring (hot spring) bathing poolSterilization, indoor and outdoor swimming sterilizing only needs 1-2ppm to be effective, and also can be used for various water treatments, and toilet disappearsPoison deodorizing, sterilization bleaching and agricultural are upper for flowers and seed disinfection, sterilization, the aspects such as aquaculture, fruit freshness preserving. ButBe that BCDMH is water insoluble, water stability is poor, and these disadvantageous features have restricted the application of BCDMH.
Summary of the invention
Goal of the invention: first technical problem to be solved of invention has been to provide a kind of instant BCDMH effervesceSheet. Second technical problem to be solved of invention has been to provide the preparation method of above-mentioned effervescent tablet. The present invention will separateThe 3rd technical problem has certainly been to provide the application of above-mentioned effervescent tablet. The present invention relates to a kind of instant BCDMH effervesceSheet, different with general sustained release tablets, it can be applied in industry and the civil applications occasion that will arrive immediately concentration, andAnd lasting sterilizing ability is strong, there are extraordinary market prospects.
Technical scheme: for achieving the above object, the present invention is achieved through the following technical solutions: a kind of BCDMH effervescent tablet,Comprise following raw material composition according to this filler of parts by weight: BCDMH 1-40 part, cosolvent 1-25 part, effervescent agent0.5-20 part, stabilizing agent 1-5 part, filler 20-96.5 part.
Wherein, above-mentioned cosolvent is urea, ammonium bromide, acetonitrile, ammonium chloride, one or several groups in isocyanuric acidBecome.
Wherein, above-mentioned effervescent agent is made up of a kind of acid and a kind of carbonate, and wherein acid is niter cake, sulfamic acid,Tartaric acid, the one in citric acid, carbonate is sodium carbonate or sodium acid carbonate.
Wherein, the above-mentioned stabilizing agent of stating refers to by sodium phosphate, sodium dihydrogen phosphate, one or more compositions in sodium hydrogen phosphate.
Wherein, the above-mentioned filler of stating is anhydrous sodium sulfate.
The preparation method of above-mentioned BCDMH effervescent tablet, comprises the following steps: first filler and stabilizing agent are put into mixingIn agitated kettle, stir 30 minutes, then add the acid plus carbonate in effervescent agent, fully stir, and then addCosolvent stirs, and finally adds BCDMH, stirs 30 minutes evenly.
Above-mentioned a kind of BCDMH effervescent tablet is prepared the application of disinfectant aspect.
Beneficial effect: compared with prior art, advantage of the present invention is as follows: the BCDMH effervescent tablet energy the present invention relates toEnough being dissolved in rapidly in water, reaches the needed concentration of sterilization; The BCDMH effervescent tablet good stability the present invention relates to,Continue sterilizing ability strong; The BCDMH effervescent tablet sterilizing ability the present invention relates to is strong, and 200ppm can kill withered black budSpore.
