Bagaimana untuk menentukan sama ada prestasi pakaian anti-statik memenuhi standard
Pakaian anti-statik ialah alatan pelindung yang biasa digunakan dalam bengkel pengeluaran mikroelektronik, paparan optoelektronik, semikonduktor, komunikasi elektronik dan industri lain. Apabila membeli pakaian anti-statik, kami amat bimbang sama ada fungsinya memenuhi standard, sama ada ia boleh melindungi produk barisan pengeluaran dengan berkesan dan memastikan kerja. keselamatan kakitangan.
Bagaimana untuk menentukan sama ada prestasi pakaian anti-statik adalah mengikut standard? Kaedah paling langsung ialah melakukan ujian rintangan permukaan pakaian anti-statik. Pakaian anti-statik yang baru dibeli atau baru dibersihkan secara amnya perlu diuji untuk prestasi pakaian-antistatik.
Tetapi sebelum melakukan ujian rintangan permukaan anti-statik, kita perlu memerhati penampilannya terlebih dahulu, kerana fabrik dan proses pakaian anti-statik mempengaruhi prestasi pakaian-statik.
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.
