(2) baking the grinding powder for about 1h at 550 ℃, paving the glass powder to a thickness of about 5cm, and allowing pure water to absorb fluoride ions to obtain hydrofluoric acid when F is separated from the glass powder and enters a cooling tower along with steam;
(3) and taking out the dried grinding powder, crushing the large blocks, rolling the small blocks, and performing mesh screening operation by using 300-mesh filter cloth to obtain the glass powder.
S5: the recycling method of the grinding powder comprises the following steps:
(1) the glass powder is subjected to the steps of fine grinding, material mixing, oxidation calcination, ball milling, screening and the like to obtain thicker particles;
(2) mixing silicon and fluorine as raw materials with particles, calcining, and finely grinding to obtain a better raw material;
(3) and filtering, drying and calcining the obtained raw materials, and carrying out surface treatment after ball milling and grading to obtain a better polishing powder product.
The comparative example 5, this embodiment obviously known, the preparation flow in the comparative example 4, the temperature improves, and high-temperature furnace time lengthens, and the mesh size grow a little more, increases at the time of toasting, and the temperature improves, and the abrasive powder polishing efficiency of output is too strong, and the cut rate spills over, and the result of use is unsatisfactory.
The following table is obtained according to examples 1 to 5:
| polishing (%) | Amount of cut (%) | Cutting Rate (%) | |
| Example 1 | 15％ | 20％ | 10％ |
| Example 2 | 50％ | 50％ | 50％ |
| Example 3 | 100& | 100％ | 100％ |
| Example 4 | 110& | 110& | 110& |
| Example 5 | 150& | 150& | 155& |
As can be seen from the above table, in example 3, the proportion of the raw materials is moderate, the temperature in the preparation process is moderate, the time in the high-temperature furnace is moderate, the mesh size is moderate, the baking time is moderate, and the temperature is moderate, so that the produced grinding powder has good polishing efficiency and cutting rate, and the using effect is ideal.
Finally, it should be noted that: the above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention are intended to be included in the scope of the present invention.
