[0002] In some military and civilian industries, a large number of high-quality substrates such as high-strength or super-strength steel are used. These substrates are mostly heat-treated at high temperatures to optimize their mechanical properties. However, a thick black oxide layer will be formed on the surface after heat treatment. When painting, it is difficult to remove, and this black oxide layer is more difficult to remove than ordinary oxidized rust
Traditionally, high-speed shot peening or pickling is mainly used. Shot peening has a great influence on the surface roughness, and special-shaped corners cannot be sprayed, and the dust pollution in the workshop is large.
Pickling is highly volatile, the equipment is highly corrosive, and it is harmful to the operator. The base material loses a lot, especially the "hydrogen" seepage is serious, and the mechanical properties of the base material are reduced, which brings certain hidden dangers to the whole machine.
At present, the use of phosphoric acid alcohol corrosion solution to remove the black scale of high-strength steel is a compromise method. Compared with strong acids such as hydrochloric acid and sulfuric acid, the amount of "hydrogen permeation" to the base material is only relatively reduced within units, and there is no Completely eliminate the "hydrogen permeation" phenomenon in the corrosion process

Embodiment 1
[0028] A neutral remover for high-temperature scale, based on 100 parts by total weight, comprising the following components by weight: 5 parts of sodium polyphosphate, 9 parts of saponin, 1.5 parts of aloe gel, 3 parts of sodium phytate, 6 parts of potassium oxalate, 3 parts of methyl borane, 6 parts of glucose, 10 parts of triethanolamine, 5 parts of vitamin C, 7 parts of 1-4-butynediol, 2.5 parts of phytic acid for pH adjustment, and the rest is deionized water.
[0029] The preparation method of above-mentioned remover is as follows:
[0030] Step 1, prepare raw materials, prepare the raw materials in the above formula, prepare aloe vera gel and saponin, and accurately weigh other ingredients; when preparing aloe vera gel in the step 1, first clean the utensils to prevent bacteria from entering the aloe vera gel; Secondly, fresh aloe is harvested and manually peeled; the fresh aloe after peeling is put into a juice maker to make juice, and then the prepared aloe juice is c...

Abstract
The invention discloses a neutral remover of high temperature oxide skin and a preparation method thereof. The neutral remover of the high temperature oxide skin consists of components of 5-9 parts ofacetylenic alcohol, 9-12 parts of plant surface activity dispersant, 10-18 parts of reductant, 17-34 parts of chelating agent, 2-3 parts of PH (potential of hydrogen) modifier and the balance deionized water. An extracting solution is prepared after removing skin of aloe gel in the plant surface activity dispersant. In preparation of the neutral remover of the high temperature oxide skin, the basic sequence of firstly adding solid, secondly adding liquid, and finally adding the reductant and solution having blistering effect is adopted for mixing all the components, and acid and alkali are dripped in the mixed components for adjusting PH value to 6.5-7.5. The remover is neutral, can completely replace modes of sand blasting, strong acid and alkali washing and the like for removing the black oxide skin, cannot cause a hydrogen permeation phenomenon or excessive corrosion to a base material, and keeps original mechanical performance of the base material. Under the synergistic effect ofthe acetylenic alcohol, the plant surface activity dispersant, the reductant and the chelating agent, the neutral remover of the high temperature oxide skin has the effects of being high in removal speed and thorough in removal. Waste liquid of the neutral remover of the high temperature oxide skin is environment friendly, and the neutral remover of the high temperature oxide skin cannot cause health or safety hazards to operation staff when used, and meanwhile can effectively recycle mono-metal powder.
