Embodiment 1
[0015] Embodiment 1: A passivation process of nanomaterials, characterized in that: the passivation process includes the following steps:
[0016] A. Feeding: Put the nano bamboo charcoal powder to be passivated into the impact mill body, and then cover the lid to keep the impact mill body sealed;
[0017] B. Oxygen injection: Fill the impact mill with a proper amount of oxygen through the breathable one-way valve, so that the oxygen concentration in the impact mill is 250-280ppm, and the gas pressure in the impact mill is 0.12-0.13MPa. If the pressure is too high, the gas pressure The balance valve automatically deflates;
[0018] C. Passivation: Passivation of nano bamboo charcoal powder in the impact mill body, the passivation time is 14 hours, and the oxygen content is monitored in real time during passivation to keep the oxygen concentration in the impact mill body at 250-280ppm;
[0019] D. Deflate and stand: Open the gas release valve, release the gas in the impact mill, and le...
Embodiment 2
[0021] Embodiment 2: A passivation process of nano materials, characterized in that: the passivation process includes the following steps:
[0022] A. Feeding: Put the nano charcoal powder to be passivated into the impact mill body, and then cover the lid to keep the impact mill body sealed;
[0023] B. Oxygen injection: Fill the impact mill with a proper amount of oxygen through the breathable one-way valve, so that the oxygen concentration in the impact mill is 280-300ppm, and the gas pressure in the impact mill is 0.13-0.14MPa. If the pressure is too high, the gas pressure The balance valve automatically deflates;
[0024] C. Passivation: Passivation of nano charcoal powder in the impact mill, the passivation time is 18 hours, and the oxygen content is monitored in real time during passivation to keep the oxygen concentration in the impact mill at 280-300ppm;
[0025] D. Deflate and stand still: Open the gas release valve, release the gas in the impact mill, and let the passivated ...

Abstract
A passivation process for nanomaterials. The passivation process includes the following steps: feeding: putting the nano-bamboo charcoal powder or nano-charcoal powder to be passivated into the impact mill body, and then covering the lid to keep the impact mill body sealed; Oxygen injection: Fill the impact mill body with an appropriate amount of oxygen through the breathable one-way valve, so that the oxygen concentration in the impact mill body is 200-300ppm, and the gas pressure in the impact mill body is 0.11-0.15MPa. If the pressure is too large, the gas pressure balance valve Automatic deflation; passivation: Passivate nanomaterials in the impact grinding body, the passivation time is 12-24 hours, real-time monitoring of oxygen content during passivation, so that the oxygen concentration in the impact grinding body is kept at 200-300ppm Deflate and leave still: open the deflate valve, let go of the gas in the impact mill, and leave the passivated nanomaterials for 1-2 hours to increase the passivation effect of the nanomaterials; discharge.
Description
Technical field [0001] The invention belongs to the technical field of nano material processing, and specifically relates to a passivation process of nano materials. Background technique [0002] Bamboo charcoal has been gradually recognized as a guardian of the environment, but bamboo charcoal as a guardian of the human body is rarely known. When people eat food, they will inevitably consume residual pesticides, preservatives and food additives, as well as dissolved substances in packaging containers, which will affect the body for a long time. Unhealthy health may cause endocrine disorders; if you eat bamboo charcoal frequently, the residual pesticides, preservatives, food additives, and solutes in the packaging container that you eat can be absorbed by the bamboo charcoal with strong adsorption and discharged together In vitro, the harm of chemicals to the body is avoided. In addition, bamboo charcoal has other beneficial effects in the human body. It can be seen that bamboo ...
