Ukukhetha i-Anti-Static Vs. Amagwebu Okuqhubayo: Okufanele Ukwazi

Igwebu elikhethekile le-ESD libalulekile ekuvikeleni amadivaysi e-elekthronikhi angaguquguquki, izakhi, nemihlangano ngesikhathi sokuthunyelwa nokugcinwa. Lapho ukhetha igwebu lalezi zinhlelo zokusebenza, kubalulekile ukuqinisekisa ukuthobela izindinganiso zezinto zokupakisha ze-EIA-541 zezinto ezizwela i-ESD. Ukuqonda umehluko phakathi kwamagwebu e-anti-static kanye ne-conductive kuzokusiza ukhethe isisombululo esifanele kakhulu sohlelo lwakho lokusebenza oluthile.

Iyini i-Anti-Static Foam?

Igwebu le-Anti-static (ESD) liklanyelwe ukunciphisa nokuhlakaza izindleko ze-electrostatic ezingalimaza izingxenye ze-elekthronikhi ezibucayi. Ivamise ukuba ne-surface resistivity kusuka ku-10⁹ kuya ku-10⊃1;⊃2; ohms futhi ivamise ukukhiqizwa kusuka ku-static-dissipative polyurethane noma izinto ze-polyethylene.

Iningi le-anti-static foam libonakala kalula ngombala walo opinki. Ilashwa ngamakhemikhali ngezithasiselo ezilwa ne-static ezinciphisa ukukhiqizwa kukagesi omile. Lokhu kwelashwa kusiza ukuvimbela ukunqwabelana okumile okubangelwa ukungqubuzana lapho izinto zinyakaza igwebu ngesikhathi sokuphatha noma sokuthutha. Kodwa-ke, ngenkathi igwebu linciphisa ukukhiqizwa okumile, alinikezi isivikelo futhi livumela amashaji angaphandle amile ukuthi adlule.

Ukuze uthole ukuvikelwa okuphelele ngesikhathi sokuthunyelwa, izinto ezizwela u-static kufanele zifakwe ngaphakathi kwesikhwama sokuvikela esinensimbi ngaphambi kokupakishwa kugwebu eliphikisayo. Ngokuvamile, i-anti-static foam ihloselwe ukusetshenziswa okulinganiselwe futhi ngokuvamile ayisebenzi kabusha.

Igwebu Elingaguquki

Igwebu eliqinile elilahlayo lenzelwe ukulawula ukugeleza kwezindleko ze-electrostatic ngokuzivumela ukuthi ziye phansi ngendlela enensa, elawulwayo—ehamba kancane kunezinto ezisebenza ngokugcwele. Ngokulawula izinga lokukhishwa, igwebu lisiza ukuvikela izingxenye ezizwelayo ezenzakalweni zokukhishwa okungazelelwe kwe-electrostatic discharge (ESD).

Leli gwebu ngokuvamile lifakwe i-carbon-impregnated futhi limnyama ngombala, noma lilashwe phezulu futhi libomvana. Ngokuvamile ayikhokhisi imali encane ekuqaleni futhi isiza ukuvimbela ukukhishwa okubangelwa ukuxhumana nomuntu. Igwebu eliqinile elichithayo ngokuvamile linokumelana nendawo okusuka ku-10⁵ kuye ku-10⁹ ohms.

Iyini i-Conductive Foam?

Igwebu le-conductive ngokuvamile lenziwa nge-polyethylene efakwe ngekhabhoni ukuze kwakhiwe isakhiwo esisebenza kakhulu. Ivamise ukuba mnyama futhi inokumelana nendawo okungaphansi kuka-10⁶ ohms.

Lolu hlobo lwegwebu luvikela izinto zikagesi nezinto ezisetshenziswayo ngokusebenza njengekheji ye-Faraday, luvimbe izinkambu kazibuthe kagesi futhi luvikele okuqukethwe kumashaji angaphandle amile. Ngenxa yaleli khono lokuvikela, ukupakishwa okwengeziwe kokuvikela okumile ngokuvamile akudingekile.

Kodwa-ke, igwebu eliqhubayo lingadonsa amabhethri uma amatheminali awo ethintana ngqo nempahla. Uma usebenzisa igwebu le-conductive ekuthumeleni noma ekugcinweni, amabhethri kufanele afakwe isithiyo esivikelayo noma ahlukaniswe kusetshenziswa ungqimba lwezinto ezingaphenduki noma ezingaguquki.
