Abstract
The invention discloses a paint film cracking detection method of enamelled wire and detection apparatus. The method comprises step of: dipping enamelled wire to be detected to brine phenolphthalein solution and electrifying, observing whether the enamelled wire in the brine phenolphthalein solution appears red within 8s to 15s, if so, the enamelled wire is cracking; if not, the enamelled wire is not cracking; the detection apparatus comprises a container (1) and an electrode (2). The brine phenolphthalein solution (3) is held in the container (1). One end of the electrode (2) is dipped into the brine phenolphthalein solution (3) and the other end is connected with a debuggable external power (4); coiling sample (5) of the enamelled wire to be detected is dipped into the brine phenolphthalein solution (3) and is connected with the debuggable external power (4) in series. The invention can detect paint film cracking state of the enamelled wire completely and accurately and reduce eyestrain of the observer, which reduces labor intensity.
Description
Technical field
The present invention relates to a kind of paint film cracking detection method of enameled wire, relate to a kind of paint film cracking pick-up unit of enameled wire simultaneously.
Background technology
Common enameled wire is when checking the pliability index, generally be to adopt the coupon of certain specification to reel to observe surperficial paint film behind the fixing turn whether cracking to be arranged or whether crackle is arranged, strict control mode normally improves amplification multiple and observes, not only increased the labour intensity of work for inspection, cause observer's eyes very easily tired, and can't judge the cracking state of paint film comprehensively and accurately, whether ftracture and just can't judge such as being wound up into inner coating surface.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of paint film cracking detection method of enameled wire, and a kind of paint film cracking pick-up unit of enameled wire is provided simultaneously.This method and device not only can be checked the paint film cracking state of enameled wire comprehensively and accurately, and can alleviate observer's kopiopia, reduction labour intensity.
For solving the problems of the technologies described above technical scheme of the present invention: a kind of paint film cracking detection method of enameled wire.It immerses enameled wire to be detected in the salt solution phenolphthalein solution, and energising, observed enameled wire and redness whether occurs in 8～15 seconds in the salt solution phenolphthalein solution, redness occurs and shows that paint film ftractures, and redness do not occur and shows not cracking of paint film.
In the paint film cracking detection method of above-mentioned enameled wire, it is all to be immersed in the salt solution phenolphthalein solution after enameled wire to be detected is reeled, thereby checks the paint film cracking state of enameled wire comprehensively.
In the paint film cracking detection method of aforesaid enameled wire, the mass percent concentration of salt solution phenolphthalein solution is a sodium chloride 0.2%, phenolphthalein 0.3%, and all the other are water.
In the paint film cracking detection method of aforesaid enameled wire, whether the observation enameled wire red time optimal occurs in the salt solution phenolphthalein solution be 10 seconds.
A kind of paint film cracking pick-up unit of enameled wire.Comprise container and electrode, be contained with the salt solution phenolphthalein solution in container, an end of electrode is immersed in the salt solution phenolphthalein solution, and the other end of electrode connects can debug external power supply; Enameled wire coiling sample to be detected is immersed in the salt solution phenolphthalein solution, and enameled wire coiling sample with can debug external power supply and connect.
In the paint film cracking pick-up unit of above-mentioned enameled wire, can debug external power supply is the 12V dc voltage power supply.
Beneficial effect of the present invention: compared with prior art, the present invention utilizes saline electrolysis to generate NaOH and chlorine principle, the enameled wire sample of winding of energising is immersed in the certain density salt solution phenolphthalein solution, and utilize phenolphthalein colour developing effect, redness in the salt solution phenolphthalein solution, whether occurs by the enameled wire coiling sample of observing energising within a certain period of time and judge whether paint film cracking occurs, not only can check the paint film cracking state of enameled wire comprehensively and accurately, and can alleviate observer's kopiopia, reduce labour intensity.
