工业用镀锡/镀锌板的镀量检测仪的研究
摘要
为了精确测量镀锡板和镀锌板的镀量,提高镀锡板和镀锌板生产和进口的质量,对镀
量检测方法进行了细致的研究,克服了传统检测方法在原理上的缺陷,从根本上解决了检
测精度问题。
本课题根据电解剥离原理,分别用稀盐酸和 NaCl 作电解液,采用微分电位法,解决了
镀锡板和镀锌板各层界面自动分层难题,对双电层电容充电电流引起的测量误差也作了修
正。研制出的检测仪以 Cygnal F005 单片机作为智能部件,既可提供本机显示和打印测量
结果的功能,又能通过 USB 接口与上位机配合使用。仪器测量精度优于 1%,分辨率
,重复性优于 %。
经过由中国食品发酵工业研究所主持的测试证明本仪器的性能指标完全达到了。本测量仪器小型轻便、操作简便、自动化程度高、检测数据精确、
价格较低,特别适用食品金属包装和汽车生产行业,具有良好的经济和社会效益,应用前
景极广阔。

RESEARCH ON PLATING DETECTOR
FOR TIN-PLATING OR ZINC-PLATING BOARD
USING IN INDUSTRY
ABSTRACT
In order to accurately detect the plating amount and improve the manufacturing and
imported quality of tin-plating board and zinc-plating board, carry on a meticulous research to
examination method of plating quantity, Overcame the blemish on the principle of traditional
examination method, resolve the problem of the examination accuracy by the root.
Based on electrolytic delamination principle,using rare hydrochloric and NaCl as electrolyte
solution, the paper adopts the method of differential electric potential to solve the problem of
being difficult to laminate automatically of tin-plating board and zinc-plating board,. It also
readjusts the error resulting from the charging current of double electrical
plating detector uses single-chip microprocessor Cygnal F005 as intelligent part, and can not
only display and print the results itself, but also cooperate with the upper machine though a USB
interface. The measuring accuracy of the apparatus is lower than 1%, the resolution is
and the repetition is superior to %.
Through the test sponsored by the Institution of China Foodstuff Ferment, the detector is
proved to have been
