Abstract
The present invention relates to a drinking water sterilizing tablet generating chlorine dioxide. The present invention is characterized in that white wax or stearic acid or beeswax or paraffin wax is used as isolating agent; sodium chlorite is made into microcapsule grains, and active chlorine or active bromine is made into disinfectant microcapsule grains by polyethylene glycol or polyvinyl alcohol; cation resin powder and tartaric acid or oxalic acid are made into solid acidulant grains. After the talc powder is added to be evenly mixed, an individual drinking water sterilizing tablet containing the active chlorine or the active bromine generating chlorine dioxide is directly pressed. The sterilizing tablet is used for the drinking and the sterilization of an arm or a tourist kettle. The generating quantity of organic carcinogen, such as trihalomethane, etc. in the drinking water after sterilized by the sterilizing tablet is reduced below 100 mu g/l.
Description
The present invention relates to a kind of preparation method who produces dioxide peroxide disinfection of drinking water sheet, more particularly, is a kind of product dioxide peroxide disinfection of drinking water sheet and production method thereof.
Dioxide peroxide is a kind of strong oxidizer, and sterilization effect is better than free chlorine, when using with chloride or bromine-containing disinfectant, not only can improve the sterilisation effect of sterilizing agent to virus, and the drinking-water after the sterilization does not produce organic carcinogens such as haloform substantially.Because its sterilisation effect is good, the using dosage of sterilizing agent is few, and cost is lower, and the drinking-water chlorine flavor after the sterilization is also less, thereby, begin to be widely used in disinfection of drinking water.At present, producing disinfection agent of chlorine dioxide is many with acidifying Textone method and protochloride sodium chlorate, because Textone very easily reacts with the sterilizing agent of solid acidifier or chloride bromine, emits dioxide peroxide, also can blast under punching press.English Patent GB1579431 has proposed to add the exhibiting high surface promoting agent and whipping agent makes Textone and the method that other compositions separate as weighting agent, has been pressed into tablet.But because preparation process has added a large amount of weighting agents, make the effective constituent in the tablet lower, and whipping agent is bigger to the PH influence of water, the sterilization sheet made from this patented method can be used for apparatus and surperficial sterilization, because the amount of surfactant that adds is excessive, make the degree of disinfection of tablet limited, and the sterilization that can not be used to drink water.
The objective of the invention is to overcome the shortcoming that above-mentioned prior art exists, provide a kind of and produce dioxide peroxide and contain available chlorine or the personal drinking water of effective bromine sterilization sheet and production method thereof.
The objective of the invention is to realize by following product and production method.Product dioxide peroxide disinfection of drinking water sheet of the present invention is to utilize Chinese wax or stearic acid or beeswax or paraffin to be separant, Textone is made microcapsule granule, with polyoxyethylene glycol or polyvinyl alcohol reactive chlorine or active bromine are made the sterilizing agent microcapsule granule, make the solid acidifier particle with positive resin-oatmeal and tartrate or oxalic acid.After the adding talcum powder mixes, can directly be pressed into the personal drinking water sterilization sheet that contains reactive chlorine or active bromine that produces dioxide peroxide.
The proportioning of product dioxide peroxide disinfection of drinking water sheet of the present invention is: the Chinese wax or stearic acid or beeswax or the paraffin that contain 0.25--0.68% weight; 1.13--1.23 the Textone of weight; The Surchlor GR 60 of 14.33--15.60% weight or chlorobromide isocyanuric acid sodium; The yellow soda ash of 1.81--1.97% weight; The polyoxyethylene glycol of 1.47--2.71% weight or polyvinyl alcohol; The tartrate of 57.56--62.65% weight or oxalic acid; 15.36 001 * 4 positive resin-oatmeal of-20.32% weight and the talcum powder of 1.47% weight.
The disinfection of drinking water sheet that contains said ratio is that the method that adopts Textone and the sterilizing agent that contains active chlorine or bromine to produce dioxide peroxide under the solid acidifier effect is produced, and may further comprise the steps:
(1) take by weighing Chinese wax or stearic acid or beeswax or paraffin by above-mentioned weight ratio, and Textone, the Chinese wax of Textone and thawing or sodium stearate or beeswax or paraffin are mixed, make the Textone microcapsule granule with 20 eye mesh screens, stand-by;
(2) take by weighing Surchlor GR 60 or chlorobromide isocyanuric acid sodium by above-mentioned weight ratio, and yellow soda ash, polyoxyethylene glycol or polyvinyl alcohol, after the mixing, mix well with 5% water, make the sterilizing agent microcapsule granule with 20 purpose nylon screens again, stand-by;
(3) take by weighing tartrate or oxalic acid by above-mentioned weight ratio, and 001 * 4 positive resin-oatmeal, after the mixing, add 10% water and mix well, make the solid acidifier particle with 20 eye mesh screens again, stand-by;
(4) Textone microcapsule granule, sterilizing agent microcapsule granule and the souring agent particle that will make through (1), (2) and (3) step respectively mixes, and makes the particle that produces the dioxide peroxide tablet;
(5) take by weighing talcum powder by above-mentioned weight ratio, after mixing with product dioxide peroxide tablet and powder, be pressed into φ 5.5mm with tabletting machine, thickness is 1.5--1.7mm, and sheet heavily is the produced dioxide peroxide of 70-100mg and the personal drinking water that contains chlorine or bromine sterilization sheet.
Because production method of the present invention is to adopt Chinese wax or stearic acid or beeswax or paraffin and Textone to make microcapsule, again with polyoxyethylene glycol or polyvinyl alcohol and contain reactive chlorine or the sterilizing agent of active bromine is made the sterilizing agent microcapsule, the sterilizing agent that makes Textone and solid acidifier or contain the reactive chlorine bromine does not react when mixing, thereby directly is pressed into personal drinking water sterilization sheet.The sterilization sheet made from the inventive method, because the concurrent disinfection effect of dioxide peroxide and chlorine bromine sterilizing agent, improved sterilisation effect, reduced the disinfectant consumption that contains reactive chlorine and active bromine, the growing amount of organic carcinogen such as haloform in the sterilization back drinking-water is dropped to below the 100 μ g/l.This sterilization sheet can be used for the disinfection of drinking water of military or tourism kettle.
