specific Embodiment approach 1

[0017] DETAILED DESCRIPTION OF THE INVENTION The method of tonal dust treatment of the present embodiment is carried out in accordance with the following steps:

[0018] First, take the sealing package of beryllium powder and inert liquid;

[0019] The inert liquid is a liquid hydrocarbon that does not react with the beryium powder at room temperature and the boiling point is less than 400 ° C, or the decomposition temperature is less than 400 ° C, and the decomposition product is a volatile product at room temperature. Object;

[0020] Second, mix the hometown powder and inert liquid in step one, resulting in a mixture;

[0021] Third, the mixture obtained by the step two is allowed to stand. After standing, the 粉 powder is fully wet with the liquid and the inert liquid is completely covered with a powder;

[0022] This embodiment has the following beneficial effects:

[0023] The present embodiment provides a method of low-cost dust-free treatment, simple, easy to operate, and b...

specific Embodiment approach 2

[0024] DETAILED DESCRIPTION OF THE INVENTION Different: The present embodiment differs from the specific embodiment: a liquid hydrocarbon that does not react at room temperature and is less than 400 ° C at room temperature and a boiling point of less than 400 ° C for kerosene, n-elevenk, n-dodexecane , Positive decane, positive decades, n-octhane or positive hexadecane; no reaction at room temperature, the decomposition temperature is less than 400 ° C, and the decomposition product is a polymer of volatile product is polymer. Ethylene glycol-200, polyethylene glycol-300, polyethylene glycol-400, polypropylene glycol-400, etc.

specific Embodiment approach 3

[0025] BEST MODE FOR CARRYING OUT THE INVENTION The third embodiment is different from the body to the body: the volume of the inert liquid is 0.5-2 times the volume of the inert liquid (natural accumulation).

Abstract

The invention discloses a method of dust-free treatment of beryllium powder, and relates to the method of dust-free treatment of the beryllium powder. The method aims to solve the problem that the dust flying phenomenon is prone to happen in the process of storage or transportation or use of the beryllium powder. The method of dust-free treatment of the beryllium powder comprises the steps that the beryllium powder which is packaged in a sealing manner and inert liquid which is packaged in a sealing manner are taken, and the beryllium powder and the inert liquid are uniformly mixed to obtain a mixture; and the obtained mixture is subjected to standing treatment, and the process is accomplished. The method of dust-free treatment of the beryllium powder is a low-cost beryllium powder non-toxic treatment, after the beryllium powder is subjected to coating liquid sealing through the low-boiling-point inert liquid, the environmental pollution and potential health hazards caused by dust flying in the beryllium powder transferring process are avoided, and the protection process is simplified while the dust-free treatment effect is achieved. The inert liquid is completely volatilized at the temperature larger than 400 DEG C and is free of residues, so that the performance of a beryllium material and the performance of a beryllium composite material are not affected. The inert liquid can effectively prevent the beryllium powder from being oxidized. The method is suitable for dust-free treatment of the beryllium powder.

Description

Technical field [0001] The present invention relates to a method of hazel dust treatment treatment. Background technique [0002] As a rare light metal, it has highlighted ratio stiffness, specific intensity, high specific heat capacity and good thermal conductivity, but also achieved significant effects in atomic reactors, but also produces important raw materials with alloys, in inertial navigation, optical systems , Missiles, satellites, astronauts and aircraft have been partially replaced aluminum, magnesium and titanium, accounting for a very important position. [0003] At present, the raw material used by the hike and the bismuth alloy is a berylium powder prepared by impacting the powder or atomized powder. It is high toxicity, and the preparation of beryllium powder is in the preparation process of storage, transportation and material. Dust flying to the human health. It creates a huge threat, inhalation of high concentration of hometown powder in the short term, will ma...
