Embodiment
[0053] A method for coating the surface of a ferrite magnetic ring, comprising the following steps:
[0054] Step 1) configure glue;
[0055] The glue is imidazole cured epoxy resin glue;
[0056] Step 1.1) Weigh 71.43% of EP01441-310 bisphenol-A epoxy resin, 21.43% of TY-203 polyamide resin and 7.14% of 2-ethyl-4-methylimidazole by weight percentage, and add to the pre-prepared glass in the container;
[0057] Step 1.2) Stir the glue evenly;
[0058] When stirring the glue, use a clean glass rod or a drill to stir the glue clockwise. When stirring, stir in the same direction and do not stir back and forth. The stirring time is more than 10 minutes, and the stirring speed is controlled at about 1r / s. Do not scratch the glassware when stirring. The inner wall is continuously stirred to avoid air bubbles and ensure that the glue is evenly stirred.
[0059] Step 1.3) After the glue is prepared, it is packaged for use, and the effective time of the glue is marked, and it is used...

The invention relates to a part surface treatment technology, in particular to a method for gluing the surface of a ferrite magnetic ring. The technical problems that in the prior art, a ferrite magnetic ring is poor in surface quality, prone to being affected by the environment and prone to falling off slag are solved. The gluing method comprises the following steps of preparing a glue solution, wherein the glue solution is imidazole cured epoxy resin glue, cleaning and drying the surface of the ferrite magnetic ring, glueing the outer circle surface, the inner circle surface and the end face of the ferrite magnetic ring, carrying out observation and quality inspection under a microscope, and curing the dried glue and forming a glue layer. After the surface of the whole ferrite magnetic ring is glued, adhesive plaster is used for a cleaning test, and it is found that the surface quality of the glued ferrite magnetic ring is greatly improved; the adhesive plaster is used for cleaning after environmental tests such as high-temperature and low-temperature tests and thermal cycle tests, the surface of the glued magnetic ring is less affected by the environment, the surface slag falling during the cleaning test is obviously reduced, and the slag falling phenomenon is well controlled.
Description
technical field [0001] The invention relates to a part surface treatment technology, in particular to a glue coating method on the surface of a ferrite magnetic ring. Background technique [0002] When receiving signals, since ordinary signal lines have no shielding layer, it is easy to form a receiving antenna to receive various messy high-frequency signals in the surrounding environment, causing interference to the original transmission signal, and even changing the original useful signal transmitted. The function of the ferrite magnetic ring is to provide a magnetic shielding environment, so that the normal and useful low-frequency signals can pass through, and it can well suppress the passage of high-frequency interference signals. It is a magnetic shielding method with obvious effect and low cost. The sensors and torquers inside the gyroscope are widely used for signal protection with ferrite magnetic rings. [0003] However, in the actual working process, most of the ...
