Abstract
The invention provides a preparation method of biological antibiotic, and relates to a preparation method of antibiotic purifying agent. The method is that: TiO2 with the weight ratio of 1:0.1 to 0.5:0.1to 0.5, heavy calcium carbonates and calcium phosphate are pumped in a jet mill at the same time, and are ground fine through the jet mill, and are mixed and processed into compound powder with grain size between 10 to 50 nanometer. The powder is the biological antibiotic. The product can be added into road surface materials, inner wall and outer wall decorative materials, architectural coating and glasses, and also can be applicable to treating industrial wastewater and waste gas, purifying automobile exhaust and tap water supply device, and also can be used in a sterile room, canteen, a swimming pool, daily tableware and so on in a hospital. The invention can kill the contacted bacteria and fungi under the action of light, and break down harmful gases which contain organic nitrogen, organophosphorus insecticide and so on into harmless small molecule substance.
Description
Technical field
The present invention relates to a kind of preparation method of sterilization purifier, particularly relate to a kind of preparation method that contains the biological disinfectant of titanium dioxide.
Background technology
Along with Increase of population and industrial expansion, the energy and environment problem receives much attention, and acid rain, depletion of the ozone layer and global warming etc. have caused global environmental crisis.Domestic and international application TiO
2Be carried on the metal surface etc. pure raw material, by ion mix up, technology such as semiconductor is compound, photoactivate, strong acid modification improve material photocatalytic properties, produce the sterilization purifier of series.But the ubiquity electricity conversion is low, the sunshine utilization less, complex manufacturing technology and industrialization cost cross problems such as height.The research of at present relevant composite oxides photocatalysis performance and the application of semiconductor complex technique make photocatalysis efficiency and sunshine utilize problem to improve, but the industrialization cost are higher, and technology is also more complicated.
Summary of the invention
The objective of the invention is to overcome existing TiO
2Sterilization purifier efficient is low, complex process, shortcoming that price is high, improves by test, provides that a kind of technology is simple, the preparation method of lower-cost sterilization purifier.This method is with TiO
2Be primary raw material, powdered whiting, calcium phosphate are auxiliary material, and is levigate through airflow milling, mix and stir and obtain this sterilization purifier.
The objective of the invention is to be achieved through the following technical solutions:
A kind of preparation method of biological disinfectant, its manufacturing process is: with the TiO of mass ratio 1: 0.1～0.5: 0.1～0.5
2Feed airflow milling simultaneously with powdered whiting, calcium phosphate; Levigate through airflow milling, hybrid process is the mixture powder of particle diameter between 10～50 nanometers, is biological disinfectant.
The preparation method of aforesaid a kind of biological disinfectant, its described TiO
2Be rutile-type technical grade TiO
2
Advantage of the present invention and effect are:
The present invention is with TiO
2Be raw material, powdered whiting, calcium phosphate are auxiliary material, and its manufacture craft is simple, cost of manufacture is cheap, the degerming good purification.
