Kwiimeko ezifana nee-semiconductors ze-elektroniki, izixhobo zokuchaneka, iikhemikhali zepetrochemicals, kunye neendawo zokusebenzela uthuli, ukuqokelelwa kombane ongashukumiyo kunokubangela iintlobo ezimbini zeengxaki: enye kukwaphulwa kwezinto ezibuthathaka yi-electrostatic discharge (ESD), kwaye enye ngumngcipheko wokutsha kwiindawo ezinokutsha neziqhumayo. Zombini ii-casters eziqhubayo kunye nee-anti-static casters zisetyenziselwa "ulawulo lwetshaja", kodwa iinjongo kunye neendlela zokuphumeza zahlukile. Ukukhetha engalunganga kunokukhokelela ekungaphumelelini kolawulo lomngcipheko.
Okokuqala, makhe sifikelele kwisigqibo: indlela yokukhetha eyona ifanelekileyo ngokujonga nje?
Xa kufikwa kwimingcipheko yokutsha nokuqhushumba (i-solvent, ioyile negesi, umngcipheko wokuqhushumba kothuli) okanye iingozi ze-ESD ezicocekileyo kakhulu/eziphantsi kwe-chip, kufuneka kubekwe phambili "kwii-conductive casters" (ezifuna ukutshajwa ngokukhawuleza kwetshaja).
Ngokuyintloko ukunciphisa ukufunxwa kwe-electrostatic kunye nokuthintela ukuphazamiseka okuncinci kokukhupha (ngesiqhelo kwimizi-mveliso ye-elektroniki kunye nokuthuthwa kwezixhobo): khetha "ii-anti-static casters" (ukuvumela ukuba iitshaja ziphele kancinci).
Nokuba yeyiphi ekhethiweyo: soloko ujonga ukuba 'ikhonkco lokumisa' ligqityiwe na, kungenjalo neeparameter ezilungileyo zinokungaphumeleli.
1. Umahluko ongundoqo: Iinjongo ezahlukeneyo → Iindidi ezahlukeneyo zokuxhathisa → Izantya ezahlukeneyo zokukhupha
1) Umqhubi we-Conductive Caster
Injongo: Ukususa ngokukhawuleza amatyala abangelwa sisixhobo/umzimba womntu, uphephe ukukhupha oko nangoko emva kokuqokelelana.
Ukuphunyezwa: Ngokwenza indlela engaphantsi kokumelana phakathi kwezinto eziqhuba umbane kunye nezakhiwo zesinyithi, iintlawulo zifakwa kwinkqubo yomhlaba/yomhlaba.
Ukumelana okuqhelekileyo: Ukumelana kwesekethe kudla ngokuba yi-≤ 10 ⁴ Ω (imigangatho eyahlukeneyo/iindlela zokulinganisa zinokwahluka, nceda ujonge ingxelo yovavanyo ukuze ufumane ukuchaneka).
Isantya sokukhupha: ngokukhawuleza (kufutshane "nokukhululwa kwangoko").
2) I-ESD/i-Dissipative Caster
Injongo: Ukuthintela ukuqokelelwa kweetshaja, ukulawula amandla e-electrostatic ngaphakathi koluhlu olukhuselekileyo, kunye nokunciphisa iingxaki zokukhupha uthuli oluncinci kunye nokuqokelelwa kothuli.
Ukuphunyezwa: Sebenzisa izinto/iinwele ezichithayo ukuze uvumele iitshaja ukuba "zikhululeke kancinci" endaweni yokulandela ukumelana okuphantsi kakhulu.
Ukumelana okuqhelekileyo: ikakhulu kuluhlu lwe-10 ⁵ -10 ⁹ Ω (ngokuqhelekileyo kwinqanaba le-10 ⁶ -10 ⁸ Ω, kusaxhomekeke kwingxelo yovavanyo).
Isantya sokukhupha: kancinci (uhlobo lokukhupha).
2. Izixhobo kunye nolwakhiwo: Ukuqhuba kufuna "indlela", i-anti-static ifuna "ukuxhathisa okulawulekayo"
1). Iindlela eziqhelekileyo zokusebenzisa ii-casters eziqhubayo:
Umzimba wevili: Ivili lerabha/le-PU/lesinyithi eliqhubayo (elingaqhelekanga), lidla ngokufumaneka ngokumelana okuphantsi ngokusebenzisa izizalisi eziqhubayo ezifana nomnyama wekhabhoni.
Isibiyeli kunye nesixhumi: Izibiyeli zesinyithi zinokwenzeka ngakumbi ukuba zenze indlela ephambili eqhuba umbane, kwaye ezinye ziya kuyilwa ngezikhombisi zokumisa umhlaba ukuqinisekisa ukuba zidibana nomhlaba oqhuba umbane.
Amanqaku aphambili: Amavili, izibiyeli, izixhobo, kunye nomhlaba kufuneka ziqhagamshelwe (ukuxhathisa ukudibana akufuneki "kucinywe").
2). Iindlela eziqhelekileyo zokusebenzisa ii-anti-static casters:
Umzimba wevili: i-PU/irabha/PP ekhuphayo, njl.njl., ezinzisa ukumelana okuphakathi ngokusebenzisa ii-anti-static agents okanye izizalisi ezikhuphayo.
Isibiyeli: Ngokwesiqhelo akufuneki uyilo olongezelelweyo lokuhambisa umoya, kodwa izahlulo zokukhusela umoya (ezifana neeplastiki, iifilimu zepeyinti ezityebileyo, imikhono yeshaft egqunyiweyo, njl.njl.) kufuneka ziphetshwe.
Ingongoma ephambili: Asikuko ukuba izinto ziqhuba kakuhle, kokukhona kungcono, kodwa endaweni yoko kufuneka ukuba ukumelana kulawulwe ngaphakathi koluhlu olunokukhupha ngaphandle kokukhawuleza kakhulu.
