Abstract
The photochemical bactericidal product includes enamel grains, enamel, ceramic and plastic product produced with photochemical catalyst and the glaze component inside the enamel and ceramic product includes silicate glaze material, TiO2, and CuO fine powder. Its production process includes enamelling the iron blank, roast at 850-900 deg.C for 3-5 min and perhaps secondary spraying and sintering. The said products can disinfect the surface of utensil, air, drink water and waste water with the disinfection rate being as high as 99.9%. Without wear and ageing, the present invention makes it possible to omit the available disinfection operation and save power.
Description
The present invention relates to the photochemical catalysis goods, belong to the B01J21/02 class, utilize the made photochemical bactericide and the manufacturing process of sterilization, decomposing organic matter performance of anatase titanium dioxide.
Reported in literature has been arranged: adopt titanium dioxide powder to be placed in the water and carry out the water sterilization experiment, since 1994 (referring to Bactericidal Activity of TiO with solar light irradiation
2Photocatalystin Aqueous Media:Toward a Solar-Assisted Water DisinfectionSystem " Environ.Scl.Technol. " Vol.28, No.5,1994) also there is the scholar to adopt aforesaid method that organism in the water is eliminated experiment, all be to use, (referring to Solarcatalytic Inactivation of ESCHERICHIA COLI in AqueousSolutions using TiO in the suspended substance mode
2As Catalyst " Chemosphere " Vol.28, No.3, pp.607-611,1994) prove that just the redox reaction that titanium dioxide carries out has sterilization effect under action of ultraviolet light, also do not enter application state; This shows that the great majority of this subject study of the present world are in the employing titanium dioxide powder carries out bactericidal assay to organism in the water the theory study stage.94 years Japanese ToTo companies and the Teng Yuzhao professor of Tokyo University's engineering portion have developed antibiotic ceramic tile and sanitary ware and have been used to prevent finishing building materials in nosocomial infection and the food factory, but point out in the literary composition that titanium dioxide is the material of powdered, can not directly bake at ceramic surface.(referring to photocatalyst anti-bacteria ceramic-antibiotic ceramic tile " world inventions " 1995,4, p16-17) production technique of the said firm is: the titanium oxide liquid starting material is sprayed on burned ceramic tile surface, fires fixing then.Spraying plating layer of copper again, silver ionized water on the fixed titanium oxide layer.The production technique of this anti-bacteria ceramic brick adds up to the secondary spraying plating, fire for three times and form.
The purpose of this invention is to provide a kind of serial photochemical bactericide, as enamel, pottery, plastics, and the manufacturing process of these goods.
Technical scheme of the present invention is as follows:
Photochemical bactericide comprises photochemical catalyst enamel particle, photochemistry Bactericidal Enamel, pottery, plastics, and the glaze proportioning components of it is characterized in that describedly warding off, ceramic is used by dry weight per-cent is: based on normal silicate class glaze 40-70%, titanium dioxide 30-60%, the oxidation copper fine-powdery 2-5% of silicon-dioxide, borax; Its manufacturing process is summarized as wards off frit for porcelain enamel in the baslled iron top layer, places 850-900 ℃ of stove to burn 3-5 minute, be divided into once sintered enamelware and ward off, the spray sintering technology of ceramic product.
Photochemical bactericide of the present invention is applied to the sterilization to tap water and waste water, air, but kill bacteria, the organism in the water is played Decomposition.This based article can comprise food and drink tool, sanitary ware, medical vessels and the various container of small stores.These goods have good sterilization effect in water sterilization is used; Test as follows: with the container that these goods are made, volume 100L, splendid attire contain intestinal bacteria 10
6Water, adopting light source is the light irradiation of long wave ultraviolet 125W, intestinal bacteria are zero in 5 minutes, reach national drinking water standard.Under no light source illuminate condition, in 2.5 hours, also can reach the standard sterilisation effect.This based article can satisfy the needs to vessel surface, air, tap water and wastewater disinfection, and does not have abrasion, problem of aging, can play germicidal action for a long time enduringly.Can ensure people health with least cost, can exempt human and material resources consumption such as existing various sterilization operations, utensil, pharmaceutical chemicals, and can save a large amount of energy, and reliable for effect to drinking water disinfection, meet People's Republic of China's national drinking water standard.Especially the photochemistry sterilization catalyzer with enamel system is not reported.The technology of these goods also has significant advantage, only compares with the anti-bacteria ceramic brick of Japan with the finished product pottery photochemical bactericide of this processes, lacks 1-2 program than its technology, and cost is low; Sterilization effect is also obviously good.Bacterium of the same race was lacked 10-15 minute on sterilizing time, and the surface disinfection rate is more than 99.9%.This sterilization effect is that the at present domestic and international experiment effect institute that reports is inaccessiable.
