A compound water fungicide

Abstract

The invention relates to the field of water body bactericides and discloses a compound water body bactericide. The compound water body bactericide is prepared from, by weight, 800-1200 parts of shell powder, 4-6 parts of magnetic powder, 4-6 parts of silicon sol, 80-100 parts of natural polyether polyol, 100-160 parts of isocyanate, 0.1-0.2 part of catalyst, 4-6 parts of phenoxy resin, 0.1-0.2 part of tea saponin and 5-10 parts of water. The compound water body bactericide can be directly put in drinking water for adsorption and sterilization and is persistent, convenient to use and recover and low in cost. The compound water body bactericide uses the shell powder as a main raw material and is safe and harmless to water quality. In addition, the specific surface area of the shell powder is large, the pore channel size distribution uniformity is good, pore channel connectivity is good, and the bacterial adsorption fastness is high.

Description

technical field [0001] The invention relates to the field of water body fungicides, in particular to a composite water body fungicide. Background technique [0002] With the improvement of people's living standards, the requirements for drinking water are also getting higher and higher. The current drinking water is generally tap water or bottled water. Although tap water and bottled water have been sterilized, if the early disinfection is not thorough during the long-term transportation and filling process, bacteria will still grow and endanger the human body. healthy. For the sterilization of drinking water, at present, ultraviolet light sterilization devices are generally installed on water dispensers, but the cost of water dispensers with ultraviolet light sterilization devices is relatively high, and the sterilization effect is average, which is not ideal and can only be turned on in a short time Sterilizing within a short period of time cannot achieve long-term steri...

Problems solved by technology

[0004] But above-mentioned nano-composite filter material is mainly with seaweed mud, zeolite and activated carbon etc. as main component, has the following disadvantages: 1, because its specific surface area is still not big enough, the contact area with water body is small, and bactericidal efficiency is low; 2, although and These materials have pores inside, which have a certain adsorption capacity for bacteria, but the size distribution of the internal pores is extremely uneven, the large ones are very small, and the small ones are very small. Bacteria cannot be adsorbed, and these channels are all single, and the connectivity between the channels is poor, so the bacteria can still "escape" after being adsorbed, and the adsorption fastness is not ideal

3. After the above materials (especially shell powder) are calcined at high temperature (above 1000°C), some basic metal oxides will be generated (such as calcium oxide after shell powder is calcined at high temperature), which will affect the pH value of drinking water

4. The above-mentioned nano-composite filter material can only be used after being installed in the filter element as a filter material, and cannot be directly dispersed into water for sterilization, so it needs to be used with a matching filter, and the cost is high
