Kif tiddetermina jekk il-prestazzjoni tal-ħwejjeġ anti-statiċi tissodisfax l-istandard
Ilbies anti-statiku huwa għodda protettiva użata komunement fil-workshops tal-produzzjoni tal-mikroelettronika, wiri optoelettroniku, semikondutturi, komunikazzjoni elettronika u industriji oħra. Meta nixtru ħwejjeġ anti-statiċi, aħna l-aktar imħassba dwar jekk il-funzjoni tagħha tissodisfax l-istandard, jekk tistax tipproteġi b'mod effettiv il-prodotti tal-linja ta 'produzzjoni u tiżgura x-xogħol. is-sigurtà tal-persunal.
Kif tiddetermina jekk il-prestazzjoni tal-ħwejjeġ anti-statiċi hijiex standard? L-aktar metodu dirett huwa li tagħmel it-test tar-reżistenza tal-wiċċ ta 'ħwejjeġ anti-statiċi. Il-ħwejjeġ anti-statiċi li jkunu għadhom kif inxtraw jew li għadhom kif ġew imnaddfa ġeneralment jeħtieġ li jiġu ttestjati għall-prestazzjoni tal-ħwejjeġ anti-statiċi.
Iżda qabel ma nagħmlu t-test tar-reżistenza tal-wiċċ anti-statiku, jeħtieġ li l-ewwel nosservaw id-dehra tiegħu, minħabba li d-drapp u l-proċess ta 'ħwejjeġ anti-statiċi jaffettwaw il-prestazzjoni ta' ħwejjeġ anti-statiċi.
The surface of the anti-static clothing should be free of damage, spots, and dirt; the sewing of the anti-static clothing should be free of skipped stitches and broken threads, and there should be "back stitches" at the beginning or end of the sewing of the two pieces.
After checking the appearance, let's carry out the surface resistance test of the anti-static clothing. Before the test: prepare the test equipment weight-hammer resistance tester, keep the temperature of the test environment at 18-25 degree , and the relative humidity RH=40-60 percent . Hang the garment to be tested in a standard environment for 24 hours to balance; connect the surface resistance tester with wires, and the tester wears anti-static overalls, wears a wrist strap and is grounded. Start the test: Lay the balanced garment on the insulating board; place the two weights of the surface resistance tester on the same surface of the garment to be tested, and the distance between the two weights is 20cm; press the test button to test , observe the direct reading on the display screen of the instrument, this reading is the surface resistance test value (unit Ω) of the tested sample, and the test result is between 105 and 1011, which is a qualified product.
