Abstract
The invention discloses a process for removing a coating on the surface of a Mn-Zn ferrite core. The process comprises the following steps of: sintering the Mn-Zn ferrite core at the temperature of between 350 and 450 DEG C for 1 to 3 hours, and cooling; and performing vibration milling on the sintered Mn-Zn ferrite core in a vibration mill for 15 to 30 minutes, and performing ultrasonic cleaning to obtain the Mn-Zn ferrite core of which the surface coating is removed. Compared with a chemical process, the process has the advantages that the treatment process is simple, the treatment speed is high, any corrosive reagent is not required to be used during treatment, the process is safe in operation and suitable for removing coatings on surfaces of Mn-Zn ferrite cores on a large scale, sewage produced in the cleaning process is easy to treat, and the environment is slightly polluted.
Description
Technical field
The invention belongs to manganese-zinc ferrite core and manufacture field, technique removed by a kind of manganese-zinc ferrite core face coat specifically.
Background technology
In order to ensure the insulating properties of product and avoid that circuit board finished product is withstand voltage to be punctured, usually can lay a coat of paint on manganese-zinc ferrite core surface, when face coat damages or change coating color, need first existing coating to be removed again to apply new coating again.This coating of existing removal commonly use technique time use special paint remover, and special paint remover is expensive, and when process quantity is very large, adopts paint remover inefficiency, simultaneously because paint remover corrosivity is strong, easily causes skin burn with human contact.Therefore, be necessary to find a kind of simple to operate, efficient, safe coating removal technique.
Summary of the invention
The object of this invention is to provide a kind of technique of simple to operate, efficient, safe removal manganese-zinc ferrite core face coat.
It is as follows that the present invention realizes the technical scheme that above-mentioned purpose adopts:
Technique removed by a kind of manganese-zinc ferrite core face coat, carries out according to following steps:
(1) manganese-zinc ferrite core sinters 1 ~ 3 hour at 350 ~ 450 DEG C, cooling;
(2) manganese-zinc ferrite core after sintering is placed in vibrating ball-mill, vibration 15 ~ 30 minutes, then Ultrasonic Cleaning, namely obtains the manganese-zinc ferrite core eliminating face coat.
Further, manganese-zinc ferrite core sinters in ladle furnace or clock hood type furnace.
If when during manganese-zinc ferrite core sintering, temperature is more than 450 DEG C, manganese-zinc ferrite core has the possibility of part generation chemical reaction, affect the performance of magnetic core, when temperature is too low (lower than 350 DEG C), the coating oxidation speed on magnetic core surface is too slow, even being difficult to oxidized, affecting coating removal effect, providing when sintering sufficient oxygen to be conducive to the ashing of coating.
Coating still covers manganese-zinc ferrite core surface after being sintered into ash, during mass simultaneous process, manganese-zinc ferrite core surface has the coating be not ashed of trace, therefore, remove by the coating of vibrating ball-mill by the non-ashing of the ash and trace that cover manganese-zinc ferrite core surface after sintering, then Ultrasonic Cleaning can obtain the manganese-zinc ferrite core of clean surface.
Beneficial effect of the present invention:
Technique of the present invention is suitable for the coating removing manganese-zinc ferrite core surface in enormous quantities, and compared with chemical treatment, processing procedure of the present invention is simple, processing speed is faster, does not need to use any corrosive reagents, handling safety in process, the sewage disposal that cleaning produces is simple, and environmental pollution is little.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described.
Embodiment 1
The manganese-zinc ferrite core of face coat to be removed is placed in ladle furnace, and temperature rises to 350 DEG C, is incubated after 3 hours and cools, and produces white powder attachment, show that coating is ashed on manganese-zinc ferrite core surface.Again the manganese-zinc ferrite core after sintering is placed in vibrating ball-mill, vibration 30min, then with supersonic wave cleaning machine, the manganese-zinc ferrite core after vibration is added water Ultrasonic Cleaning totally, obtain the manganese-zinc ferrite core of clean surface.
Embodiment 2
By the step process manganese-zinc ferrite core described in embodiment 1, difference is, the temperature of ladle furnace is raised to 400 DEG C, is incubated 2 hours, vibration 20min in vibrating ball-mill.
Embodiment 3
By the step process manganese-zinc ferrite core described in embodiment 1, difference is, sintering carries out at clock hood type furnace, and temperature is 450 DEG C, is incubated 1 hour, vibration 15min in vibrating ball-mill.
Claims (2)
1. a technique removed by manganese-zinc ferrite core face coat, it is characterized in that, carry out according to following steps:
(1) manganese-zinc ferrite core is little of manganese-zinc ferrite core surface generation white powder attachment at 350 ~ 450 DEG C of sintering 1 ~ 3, cooling;
(2) manganese-zinc ferrite core after sintering is placed in vibrating ball-mill, vibration 15 ~ 30 minutes, then Ultrasonic Cleaning, namely obtains the manganese-zinc ferrite core eliminating face coat.
2. technique removed by manganese-zinc ferrite core face coat as claimed in claim 1, it is characterized in that: manganese-zinc ferrite core sinters in ladle furnace or clock hood type furnace.
