Shoveling liquid and preparation process thereof

Abstract

The invention discloses shoveling liquid and a preparation process thereof, relates to the technical field of metal surface oxide treatment, and solves the problem that a large amount of hazardous waste liquid is likely to be generated when metal oxides on the surface of a metal workpiece are removed, so that the environmental protection is not facilitated. The shoveling liquid comprises the following components including, by weight, 10-30 parts of hawthorn extracts, 8-15 parts of potato extracts, 7-10 parts of licorice extracts and 45-75 parts of deionized water. The preparation process mainly comprises the following steps that mixing and dissolving are conducted on the raw materials, filtering and impurity removing are conducted, and the product is obtained. The shoveling liquid has a good shoveling effect on the metal oxides on the surface of the metal workpiece, does not generate hazardous waste liquid in the using process, is beneficial to environmental protection and has a good application effect.

Description

technical field

[0001] The invention relates to the technical field of metal surface oxide treatment, more specifically, it relates to a shoveling liquid and a preparation process thereof. Background technique

[0002] During the long-term use of metal workpieces, affected by the external environment, a layer of metal oxide is likely to be formed on the surface, which will greatly reduce its overall performance. Therefore, it is necessary to treat the metal oxide on the surface regularly to keep it Good and stable performance.

[0003] A method for removing oxides is disclosed in the Chinese invention patent with the publication number CN102418110A, which includes: reacting the oxides with a composition to generate a resultant product, the composition comprising carbonates of alkali metals, oxides , hydroxide, or oxalate, or combinations or reaction products of alkali metal carbonates, oxides, hydroxides, or oxalates with boron oxide or boric acid; clear the resulting produ...

Examples

Embodiment 1

[0037] Embodiment 1: A kind of shoveling liquid, each component and its corresponding parts by weight are as shown in Table 1, and are prepared through the following steps:

[0038] Step 1, mixing the raw materials, stirring and mixing the hawthorn extract, potato extract, licorice extract and deionized water in corresponding parts by weight in a mixing tank, the stirring speed is 50r / min, and the time is 30min, to obtain a mixed solution;

[0039] Step 2, filter to remove impurities, filter the mixed liquid in step 1 with a 200-mesh screen to remove impurities, then centrifuge to precipitate, and take the supernatant to obtain the eradicated liquid.

[0040]Note: The hawthorn extract in step 1 is specifically obtained by the following extraction steps: take the hawthorn raw material, slice it, then soak it in 3 times the amount of 80% ethanol solution, heat it to 65°C for 2 hours, and filter to obtain the primary extraction liquid and filter residue; after concentrating the i...

Embodiment 2-8

[0043] Embodiment 2-8: A shoveling solution. The difference from Embodiment 1 is that each component and its corresponding parts by weight are shown in Table 1.

[0044] Each component and parts by weight thereof in table 1 embodiment 1-8

[0045]

Embodiment 9

[0046] Embodiment 9: A kind of eradicating liquid, the difference with embodiment 1 is that step 1 is specifically set as, mixing raw materials, the corresponding parts by weight are 10 parts of hawthorn extract, 8 parts of potato extract, 10 parts of licorice extract, 6 parts of cypress leaf extract and 45 parts of deionized water were stirred and mixed in a mixing tank at a stirring speed of 50 r / min for 30 min to obtain a mixed solution. The cypress leaf extract was purchased from Xi'an Qiancao Biotechnology Co., Ltd.
