Anti-static table mats burning resistance test
Anti-static table mat, as a kind of rubber product, is in the common impression that people cannot help but burn, so when choosing anti-static products in some industries, anti-static table mats are often ignored, but in fact, the current anti-static table mats It often has good burning resistance, and the manufacturer will also attach the corresponding test report when it is sold, but we all hope to have a more intuitive feeling before use. Today, the editor will introduce to you one from "HG-T3747.1- 2011" method of testing the anti-static table mat's burning resistance.
First, cut the anti-static table mat to be tested into a square with a side length of 10 cm or more, wipe the surface with degreased gauze, take three male cigarettes, several of each type, remove the filter, and place it in a working indoor environment. hour. Then, ignite the cigarette in an indoor airless environment, let it burn by itself for 10 seconds, lay it flat on a selected test site on the anti-static table mat sample to be tested, and still let it burn by itself for 10 seconds before taking it away ( If the cigarette is extinguished midway, re-select the test point), then continue to select two pilots to repeat the above steps (the distance between the pilots is greater than 5cm), and finally wipe the surface of the anti-static bench pad under natural light with a cotton cloth moistened with ethanol. °Look down and observe from a distance of 80cm.
Because cigarettes burn on their own at normal temperature and pressure, the surface temperature is 550℃—600℃, and the center temperature is about 830℃. Industries that need to use high-temperature objects for processing, such as soldering in the electronics industry, generally do not Above 550°C, so the above test can be a more intuitive test of the anti-static mat's burning resistance.
