Abstract
The invention belongs to the technical field of metal surface treatment of electrical vacuum devices, in particular to an acid-free surface treatment technology of electrical pure iron and stainless steel parts for an electrical vacuum device. The invention aims to provide an environment-friendly surface treatment technology specific to problems and defects in the conventional part surface treatment technology. The technical solution is implemented by mechanical grinding, cleaning and polishing, water washing, dehydrating and vacuum degassing. The acid-free surface treatment technology has the beneficial effects that (1) the four steps of cleaning and polishing in the conventional surface treatment process are reduced to one step of mechanical grinding, cleaning and polishing; (2) various acids and alkalis which cause pollution and are harmful to the environment are not used, so that the technology is environmentally friendly; (3) bending positions of parts can be ground and polished by disc-shaped polishing balls, and residual burrs on the parts can be removed effectively; (4) cleaning and polishing processes are finished automatically. Compared with the conventional process, the acid-free surface treatment technology has the advantages that the process steps are simplified, the efficiency is increased, labor force is reduced, and the technology is environmentally friendly.
Description
Technical field
The invention belongs to electron tube field of metal surface treatment technology, relate to a kind of electron tube metal parts surface treatment purification techniques, is that one is specially adapted to electron tube electrical pure iron and stainless steel parts anacidity process for treating surface.
Background technology
Electrical pure iron and stainless steel material extensive application in electron tube,---washing---pickling---washing---electropolishing (as required)---washing---dehydration---vacuum degassing that the technical process of traditional electrical pure iron and stainless steel parts surface treatment technology is deoiled.
(1) deoil:
Preparing metal cleaning fluid, its formula is:
| Title | Content | Unit |
| Metal cleaner | 50 | g |
| Water | 950 | ml |
Heated wash more than 2 hours.
(2) pickling:
Preparating acid washes down washing lotion, and its formula is:
| Title | Content | Unit |
| Deionized water | 75 | ml |
| Hydrofluoric acid | 5 | ml |
| Sulfuric acid | 5 | ml |
| Phosphoric acid | 10 | ml |
| Nitric acid | 5 | ml |
(3) electropolishing
Preparation electropolishing solution, its formula is:
| Title | Content | Unit |
| Deionized water | 9 | ml |
| Chromic anhydride | 9 | g |
| Phosphoric acid | 70 | ml |
| Sulfuric acid | 12 | ml |
The shortcoming of said method is that processing step is more, process relative complex, length consuming time, and cleaning process all relies on and manually completes, and the improper meeting of liquid waste processing produced after institute's Cleaning of Parts causes environmental pollution.
Summary of the invention
Object of the present invention is exactly for the problem and shortage part existing for electron tube electrical pure iron and stainless steel parts surface treatment technology, and provides a kind of process for treating surface of environmental protection.
---washing---dehydration---vacuum degassing that technical solution of the present invention is: mechanical lapping cleaning polishing.
Mechanical lapping cleaning polishing: cleaning and polishing are united two into one, uses vibratory finishing machine and dish-shaped polishing pearl to carry out vibro-grinding polishing to needs surface-treated part.Simultaneously in vibratory finishing machine, according to the size of polishing machine volume and the quantity of polishing pearl, appropriate cleaning agent special for stainless steel and special throwing photo etching is added by 1:1, add appropriate water mixing again, after opening vibratory finishing machine, clean the technological requirement that grinding and polishing can reach piece surface process for 60-70 minutes.
The invention has the beneficial effects as follows: (1) is 1 by traditional metal parts process of surface treatment, 4 operating procedures of cleaning polishing simplify---mechanical lapping cleaning polishing; (2) do not use generation to pollute, all kinds of soda acids of hostile environment, the cleaning agent special for stainless steel adopted and polishing agent are neutral flux, environmental protection; (3) dish-shaped polishing pearl can carry out grinding and polishing to spares bend position, and effectively can remove the burr remnants of part; (4) cleaning polishing process completes automatically, and consuming time short, efficiency is high, does not need manual operation; (5) scheme provided by the invention can not only be applicable to electrical pure iron and the process of stainless steel parts surface, also can be used for other hard metal and alloy.
Claims (1)
1. an electron tube electrical pure iron and stainless steel parts anacidity process for treating surface, simplify the step of traditional handicraft, be 1 by traditional metal parts process of surface treatment, 4 operating procedures of cleaning polishing simplify---mechanical lapping cleaning polishing, cleaning and polishing are united two into one, technique can be reduced greatly consuming time, manual operation is changed into automatical and efficient mechanical lapping, and whole process is pollution-free compared with traditional handicraft, environmental protection.
