Mu zochitika monga ma semiconductor amagetsi, zida zolondola, mankhwala a petrochemical, ndi malo ochitira fumbi, kusonkhanitsa magetsi osasunthika kungayambitse mitundu iwiri ya mavuto: limodzi ndi kuwonongeka kwa zigawo zomvera ndi kutulutsa kwamagetsi (ESD), ndipo lina ndi chiopsezo cha kuyaka m'malo oyaka moto komanso ophulika. Ma casters onse oyendetsera magetsi ndi ma casters otsutsana ndi magetsi amagwiritsidwa ntchito pa "kasamalidwe ka magetsi", koma zolinga ndi njira zogwiritsira ntchito ndizosiyana. Kusankha kolakwika kungayambitse kulephera kwa kuwongolera zoopsa.
Choyamba, tiyeni tipereke yankho: momwe mungasankhire yoyenera mwachangu?
Ponena za ngozi zoyaka moto ndi kuphulika (zosungunulira, mafuta ndi gasi, zoopsa zophulika fumbi) kapena zoopsa za ESD zoyera kwambiri/chip level, choyamba chiyenera kuperekedwa kwa "conductive casters" (zomwe zimafuna kuti chaji itayike mwachangu).
Makamaka kuti muchepetse kuyamwa kwa magetsi komanso kupewa kusokoneza pang'ono kutulutsa madzi (nthawi zambiri m'mafakitale amagetsi ndi mayendedwe a zida): sankhani "zotsukira zotsutsana ndi magetsi" (kuti magetsi azitha pang'onopang'ono).
Kaya ndi iti yomwe yasankhidwa: nthawi zonse onani ngati 'ulalo wolumikizira' watha, apo ayi ngakhale magawo abwino kwambiri angalephere.
1. Kusiyana kwakukulu: Zolinga zosiyana → Mitundu yosiyanasiyana ya kukana → Liwiro losiyana la kutulutsa
1) Chotsitsa Choyendetsa
Cholinga: Kuchotsa mwachangu mphamvu zomwe zimapangidwa ndi chipangizo/thupi la munthu, kupewa kutuluka nthawi yomweyo mutasonkhanitsa.
Kukhazikitsa: Mwa kupanga njira yocheperako yolimbana pakati pa zipangizo zoyendetsera ndi zomangamanga zachitsulo, ma charge amalowetsedwa mu dongosolo la nthaka/pansi.
Kukana kwanthawi zonse: Kukana kwa dera nthawi zambiri kumakhala ≤ 10 ⁴ Ω (miyezo/njira zosiyanasiyana zoyezera zimatha kusiyana, chonde onani lipoti la mayeso kuti muwone kulondola).
Liwiro lotulutsa: mwachangu (pafupi ndi "kutulutsa mwachangu").
2) ESD/Dissipative Caster
Cholinga: Kuletsa kusonkhanitsa mphamvu zamagetsi, kuwongolera mphamvu zamagetsi zomwe sizingagwere m'malo otetezeka, ndikuchepetsa mavuto otulutsa mpweya ndi fumbi.
Kugwiritsa Ntchito: Gwiritsani ntchito zinthu zotayira/zophimba kuti magetsi "atuluke pang'onopang'ono" m'malo motsatira kukana kochepa kwambiri.
Kukana kwachizolowezi: makamaka pakati pa 10 ⁵ -10 ⁹ Ω (nthawi zambiri pamlingo wa 10 ⁶ -10 ⁸ Ω, komabe kumayang'aniridwa ndi lipoti la mayeso).
Liwiro lotulutsa: pang'onopang'ono (mtundu wotulutsa).
2. Zipangizo ndi Kapangidwe: Kuyendetsa magetsi kumafuna "njira", anti-static kumafuna "kukana kolamulirika"
1) Njira zodziwika bwino zogwiritsira ntchito ma casters oyendetsera magetsi:
Thupi la gudumu: Gudumu la rabara/la PU/lachitsulo loyendetsa galimoto (losowa), nthawi zambiri limapezeka ndi mphamvu zochepa kudzera mu zodzaza ma conductor monga carbon black.
Bulaketi ndi cholumikizira: Mabulaketi achitsulo amatha kupanga njira yayikulu yoyendetsera magetsi, ndipo ena adzapangidwa ndi zolumikizira pansi kuti zitsimikizire kuti zikugwirizana ndi nthaka yoyendetsera magetsi.
Mfundo zazikulu: Mawilo, mabulaketi, zida, ndi pansi ziyenera kulumikizidwa (choletsa kukhudzana sikuyenera "kuchotsedwa").
2) Njira zodziwika bwino zogwiritsira ntchito ma casters oletsa kusinthasintha:
Thupi la gudumu: PU/rabala/PP yotulutsa mpweya, ndi zina zotero, kukhazikika kwa kukana kwapakati kudzera mu anti-static agents kapena dissipative fillers.
Bulaketi: Nthawi zambiri sipamafunika kapangidwe kena kowonjezera ka conductor, koma magawo oteteza kutentha (monga ma pulasitiki, mafilimu okhuthala a utoto, manja a shaft oteteza kutentha, ndi zina zotero) ayenera kupewedwabe.
Mfundo yofunika: Sikuti zinthuzo zikamayenda bwino, zimakhala bwino, koma kuti kukana kuyenera kulamulidwa mkati mwa malo omwe angathe kutulutsa popanda kuthamanga kwambiri.
