Problems solved by technology

However, the dust generated during the polishing process will cause pollution, and long-term inhalation of dust by the human body will pose a threat to health, so dust removal is required during the polishing process
[0003] The current dust removal process mostly uses negative pressure fans to pump the dust out of the factory building, but due to the light amount of dust, it is easy to disperse and difficult to discharge completely, and the larger dust generated during the polishing process is difficult to extract and will remain in the factory building
In addition, when dust such as magnesium powder and aluminum powder is enriched to a certain extent, it may cause an explosion, so it is necessary to provide a dust removal process and a polishing dust removal agent that can quickly and completely absorb the dust generated by polishing

preparation example Construction

[0056] In a preferred embodiment, the preparation method of the ionic liquid of the present invention comprises the following steps:

[0057] 1) heating N-methylimidazole to 40-50°C, adding butane sultone to react, washing and drying to obtain intermediate A;

[0058] 2) React intermediate A and p-toluenesulfonic acid at 110-130°C, lower the temperature to 90-100°C, wash and dry to obtain the ionic liquid.

[0059] The present invention reacts N-methylimidazole (CAS No.: 616-47-7) and butane sultone (CAS No.: 1633-83-6) to generate sulfonate-containing imidazole inner salt, and reacts with p-toluenesulfonic acid Generate imidazole acidic ionic liquids, containing both nitrogen cations and p-toluenesulfonate anions.

[0060] In order to improve the absorption speed of the medicament to dust, the applicant added an appropriate amount of ionic liquid to the medicament, and found that the addition of ionic liquid can greatly improve the absorption efficiency of the medicament to ...

Embodiment 1～15

[0104] Embodiments 1-15 provide a preparation method of polishing and dust-removing agent, comprising the following steps:

[0105] The preparation raw materials of the polishing and dust-removing agent are mixed to obtain the polishing and dust-removing agent.

[0106] performance evaluation

[0107] 1. Dust absorption performance:

[0108] (1) Dust absorption: At 28°C, under normal pressure, add an equivalent amount of polishing dust removal agents provided in Examples 1 to 15 respectively in the dust absorption bottle, and then pass it into the magnesium alloy and aluminum alloy for polishing at a speed of 60mL / min. For the dust generated during the test, test the weight gain of the dust absorbing article until the weight of the absorbing article no longer changes to calculate the weight of the dust absorbed by the medicament. The results are shown in Table 2.

[0109] (2) Dust secondary absorption: After the medicaments provided in Examples 1 to 15 after absorbing the d...

Abstract

The invention relates to the field of dust removal processes, in particular to a polishing dust removal agent and a dust removal process. The dust removal process comprises the polishing dust removalagent dust removal and the dust collection tower dust removal. The dust removal process provided by the present invention can be used for rapidly and comprehensively removing the dust and preventing the dust residues. By discharging the dust generated during the polishing process, the phenomena of combustion, explosion and the like caused by the dust enrichment are prevented, and the environmentalpollution and the inhalation danger of a human body are prevented. In addition, the polishing dust removal agent for the dust removal process can rapidly absorb the dust, the volatilization of an acidic dust removal agent can be reduced by adding the trifluoroacetic acid and thep-toluenesulfonic acid, so that safety is improved. The polishing dust removal agent can be repeatedly used by adding the ionic liquid.

Description

technical field [0001] The invention relates to the field of dust removal technology, and more specifically, the invention relates to a polishing dust removal agent and a dust removal technology. Background technique [0002] Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is an important process step in many production processes. Most metal products need to be polished. Processing to enhance the aesthetics of appearance. However, the dust generated during the polishing process will cause pollution, and long-term inhalation of dust by the human body will pose a threat to health, so dust removal treatment is required during the polishing process. [0003] The current dust removal process mostly uses negative pressure fans to pump the dust out of the factory building. However, due to the light amount of dust, it is easy to disperse and difficult to discharge...
