Example Embodiment

[0026] Example 1:

[0027] The raw materials of nano silver disinfectant are as follows:

[0028]

[0029] Preparation method: start the power supply of the device, adjust the voltage of the three cathodes and anodes inside the nano-silver generating chamber to 10kV, set the anode silver rod feed rate to 0.1mm / min, and the working gas purge rate to 10m 3 / min, the production rate of nano silver is 10g / min. The nano silver enters the storage chamber with the airflow and is separated by the gas-solid separator, and falls into the bottom for storage. Nano-silver enters the dispensing chamber from the storage chamber at a feed rate of 5g / min. Nano-silver stabilizers, dispersion protectants, additives, and solvents are used at 50g / min, 15g / min, 10g / min, and 5000g / min. The feed rate is added to the dosing chamber from the feed tank. All the raw materials are mixed evenly in the dispensing chamber to obtain a stable nano-silver disinfectant, which is then extracted from the discharge po...

[0034] Preparation method: start the power supply of the device, adjust the voltage of the three cathodes and anodes inside the nano-silver generating chamber to 20kV, set the anode silver rod feed rate to 0.2mm / min, and the working gas purge rate to 10m 3 / min, the production rate of nano silver is 20g / min. The nano-silver enters the storage chamber with the airflow and is separated by the gas-solid separator and falls to the bottom. Nano-silver enters the dispensing chamber from the storage compartment at a feed rate of 10g / min. Nano-silver stabilizers, dispersion protectants, additives, and solvents are used at 70g / min, 30g / min, 20g / min, and 5000g / min. The feed rate is added to the dosing chamber from the feed tank. All the raw materials are mixed evenly in the dispensing chamber to obtain a stable nano-silver disinfectant, which is then extracted from the discharge port.

Abstract

The invention discloses a process method for preparing a nano-silver disinfectant based on an electric explosion process. The preparation principle is as follows: electric explosion is generated through high voltage of an independent cathode and a corresponding anode, then, instantaneous high temperature is formed to evaporate metal silver, atomic-state metal silver performs irregular thermal motion in a nano-silver generation chamber and is condensed into nano-silver particles after colliding and coalescing with each other, the nano-silver particles enter a storage chamber through a pipelinealong with working airflow, the nano-silver particles in gas are filtered by a gas-solid separator in the storage chamber, and the filtered nano-silver particles fall into the bottom to be stored. Andthe nano-silver in the storage chamber can enter a preparation chamber and is mixed with a solvent to generate the nano-silver disinfectant. The disinfectant comprises nano-silver, a nano-silver stabilizer, a dispersion protective agent, an auxiliary agent and the solvent. Compared with an existing preparation method of the nano-silver disinfectant, the process method has the following advantages: the production rate of the nano-silver can be regulated and controlled, the nano-silver disinfectant can be continuously prepared for a long time, various nano-silver disinfectants with different proportions can be prepared, and the nano-silver disinfectant is high in preparation efficiency, simple to operate and high in cost performance.

Description

technical field [0001] The invention relates to the field of nanotechnology and fine chemical industry, in particular to a process for preparing nano-silver disinfectant based on an electric explosion method. Background technique [0002] Since the beginning of the 21st century, with the development of society and the improvement of people's living standards, people have put forward higher requirements for environmental conditions and health. Bacteria, viruses, etc., especially those harmful to humans and animals, can cause many major diseases. They themselves have a large reproductive capacity, constantly encroaching on people's normal life, and people's health is seriously threatened. The current sterilization and disinfection technology is still not perfect. Thermal sterilization, such as high temperature and high pressure sterilization, is too strong, which may damage the nature of the product itself. Nano-silver is a new type of nano-material. In addition to its excell...
