Radioactivity is one of the important indexes to measure whether ceramic tile causes serious indoor pollution or not. As some testers did not grasp the influencing factors well, the test results of some laboratories deviated.This paper mainly expounds the influence of the radioactive detection results of ceramic tile from four aspects: wet sample, cross contamination ,sealing balance time and temperature.
According to the contents of the latest edition of the standard, the paper provides a fast and efficient washing test device which can fully meet the pollution resistance of ceramic tiles. The realization of the ceramic tile pollution resistance test device will make the test cleaning procedures to be quantified, and easy to operate, simple, shorten the test time, improve the test efficiency, with fast experimental results, high accuracy, small error, high efficiency and a wide range of application. The experiment time is shortened but the experiment result is accurate and efficiency is greatly improved.
