The disinfectant may be used in the fields of public health, food processing, cultivation, etc. and has the advantages of fast dissolving speed, wide bactericidal spectrum, stable performance, easy dissolving in water, no environmental pollution, etc.
Description
Technical field
The present invention relates to the preparation and the application of Halogen disinfectant, especially relating to a kind of is the preparation and the application of the disinfectant of carrier with the nano material.
Background technology
In the at present used disinfectant, the Halogen disinfectant is widely used one big class disinfectant, and occupies very big market in the disinfection field.And in the Halogen disinfectant, have only the chlorine-containing disinfecting bactericide and contain disinfectant germicide as what disinfectant used at present, the former comprises inorganic chloride, as follows (calcium hypochlorite is main for sodium chlorate's (10% to 20%), bleaching powder (25%), bleaching powder, 80% to 85%) chlorination tri-sodium phosphate (3% to 5%); Organochlorine compound as, receive (60% to 64%) sym-closene (87% to 90%) etc. as dichlord isocyanurice acid; Contain disinfectant germicide and mainly comprise the tincture of iodine and Iodophor etc., containing iodine disinfectant is a class middle effect disinfectants, can only kill general bacterial propagule, virus, fungi, and can not the kill bacteria gemma, therefore uses limitedly, is mainly used in the sterilization of skin and mucosa.The chlorine-containing disinfecting bactericide then is the high-effective disinfecting bactericide, it can kill the multiple microorganism that comprises pathogenic gemma, be used for sterilizations such as environment, article surface, tableware, drinking water, sewage, excreta more, sterilization effect is good, but its fatal shortcoming is that the strong impulse smell is arranged, be corrosive, the aqueous solution decomposes easily, instability, easily produces carcinogens such as chloroform when being used for water sterilization.That rise at present just but not widely used as yet two chlordantoins and bromine-chlorine-dimethyl hydantoin disinfectant, though its Disinfection Effect has improvement, but their solvability is very little, only about 0.2%, the DBDMH disinfecting agent Disinfection Effect has good disinfection efficacy than above-mentioned disinfectant, but 20 ℃ the time, the water-soluble 2.2g C5H6Br2N2O2 of separating of 1L, dissolubility is very low, influenced greatly its as disinfectant the sterilization Application for Field.Therefore press for the chlorine-containing disinfecting bactericide seeking a kind of efficient, low toxicity, stable disinfectant and substitute application at present, contain iodine disinfectant and bromine-containing disinfectant.
For this reason, the inventor has carried out a large amount of research and experiment in recent years to this, and having developed a kind of is the application of carrier as disinfectant with the nanometer silica gel material, it is advantageous that have wide spectrum, efficient, safety, low toxicity, characteristics such as stable.
Silica gel is a kind of high activity adsorbent, belongs to amorphous state, and chemical property is stable, forms different microcellular structures because of its manufacturing process is different, has the advantage that other same type of material hardly matches, absorption property and Heat stability is good, mechanical strength height.Employing is with the disinfectant of nanometer silica gel as carrier, its advantage is that silica gel is the colloidal state system with solid property, form the colloidal particle of agglutinate structure, colloidal particle is the condensation polymer of hydration status silica gel (many silica gel), the gap of the aggregate of colloidal particle forms the micro hole structure of silica gel particle inside, therefore it is a kind of microcellular structure of enriching that has, high-specific surface area, high-purity, highly active high-quality sorbing material, adsorptivity is strong, raw materials such as dibromo dimethyl hydantoin fully can be adsorbed in silica gel particle surface and the micropore, in water, form with suspended state, solved the problem that dibromo dimethyl hydantoin is slightly soluble in water, but in water slurry, dibromo dimethyl hydantoin and water reaction, constantly discharge the active bromine ion, form hypobromous acid again, then produce nascent oxygen, molecular bromine, thereby oxidizing bacteria, virus, algae, protozoan cell surface and inner enzyme and protein, play the sterilizing effect, can make simultaneously the oxygen in the water body, nitrite, hydrogen sulphide etc. are oxidized to innocuous substance, increase dissolved oxygen in water.
Summary of the invention
The present invention is preparation and the application of carrier as disinfectant for the technical problem that exists in the solution known technology provides a kind of with the nanometer silica gel material.It is advantageous that have wide spectrum, efficient, safety, low toxicity, characteristics such as stable.
