Emisebenzini yethu yansuku zonke kanye nemibuzo yamakhasimende, sithole ukuthi kunemibuzo eminingi mayelana-namazinga amile "e-anti{1}}ephikisana ne-static silicone foam board" phakathi kwabantu. "I-anti{3}}i-static" kanjani nje? Yiziphi izindinganiso zokuhlola ezigunyaziwe? Yiziphi izidingo ezihlukene zezimo zohlelo lokusebenza ezahlukene? Namuhla, ake sikucacise kahle.
一, Izinkomba Eziyinhloko: Ukungazweli kuyisihluthulelo
Inkomba ewumnyombo yokulinganisa-ukusebenza okuqinile ukuphikiswa. Ngokwendlela okudlula ngayo okwamanje, sigxila kakhulu kumapharamitha amabili:
1.I-Surface Resistivity (i-surface Resistivity) : ukumelana kwento uma imanje igeleza endaweni yayo. Iyunithi: Ohm (Ω)
2. I-Volume Resistivity (Ukumelana nevolumu) : ukumelana kwento uma imanje idlula kukho. Iyunithi: Ohm ·cm (Ω·cm).
Okwezinto ezivundlile njengerabha ye-silicone enegwebu, ukumelana nevolumu ngokuvamile kuyinkomba ebaluleke kakhulu njengoba kungabonisa ngokuphelele ukuqhutshwa kukagesi kukonke.
2, Amazinga Ajwayelekile kanye Nokuhlelwa Kwebanga Okwamanje.
Ayikho indinganiso eyodwa ehlangene ngokuphelele yokuhlukaniswa kwebanga{0}kwezinto eziqinile ezimelene namazwe ngamazwe. Kodwa-ke, amasistimu namazinga alandelayo ajwayelekile acashunwa kakhulu futhi amukelwe:
1. Amazinga e-ESD Association (ESDA).- Uhlelo olugunyazwe kakhulu lwe-Electrostatic Protection Amazinga akhiwe yi-Electrostatic Discharge Association yase-United States ayizinkomba ezigunyazwe kakhulu embonini yezogesi. I-ANSI/ESD S20.20 yayo evamile ihlukanisa izinto ezisetshenziswayo zibe izigaba ezintathu, okubalulekile ekuqondeni kwethu -ibanga elimile:
1)Izinto ezisebenzayo (I-Conductive) : ukumelana nendawo: ngaphansi kuka-1 x 10⁴ Ω (okungukuthi,<10,000 Ω) volume resistivity: Less than 1 x 10⁴ Ω·cm. Characteristics: The charge dissipates extremely fast, which may cause rapid discharge of electrostatic sensitive components (CDM damage). It is often used in situations where grounding is required and charges need to be discharged quickly, such as anti-static floors and table MATS.
2)Impahla yokulahla engashintshi (i-static Dissipative) : ukumelana nendawo: 1 x 10⁴ Ω kuya ku-1 x 10¹¹ Ω ukumelana nevolumu: 1 x 10⁴ Ω·cm kuya ku-1 x 10¹¹ Ω·cm izici: leli ibanga elivame kakhulu le-silicone ye-anti foam{9}! Ingakhipha amashaji amile phansi ngesivinini esilawulekayo nesinensa uma kuqhathaniswa, igweme ukukhiqizwa kwamaza amakhulu asheshayo, futhi ngaleyo ndlela ivikele ngokuphephile izingxenye eziningi ze-elekthronikhi.
3)Into evikelayo: Ukumelana nobuso: okukhulu noma okulingana no-1 x 10¹² Ω (okungukuthi, Okukhulu noma kulingana no-1,000,000,000,000 Ω) Ukumelana nevolumu: okukhulu noma okulingana no-1 x 10¹² Ω·cm kagesi Izici: Ishaja kagesi emile ayikwazi ukugeleza futhi imile. Irabha ye-silicone evamile iwela kulesi sigaba.
2. Ezinye izindinganiso ezivamile
I-ASTM D257: I-American Society for Testing and Materials standard, okuyindlela ejwayelekile yokuhlola ukukala ukumelana okuqondile kwamanje noma ukuqhutshwa kwezinto zokuvikela.
I-IEC 61340: Izinga le-International Electrotechnical Commission, elifana nezinga le-ESDA, liphinde libe wuhlelo olujwayelekile olwamukelwa umhlaba wonke lokuvikela ugesi.
Amazinga ezempi afana ne-MIL-PRF-87893: Anezidingo eziqinile nezicacile zokusebenza kwempahla ephikisana ne-static.
Izinga eliphikisayo-elimile lamabhodi egwebu alwa-eliqinile le-silicone ngokuyinhloko lincike ekutheni ivolumu/ukumelana kwayo nobuso kungena ngaphakathi kobubanzi be-"static dissipation" obungu-10⁴ ukuya ku-10¹¹ Ω·cm. Ibuphi -ububanzi obukhethekile obukhethayo buncike ekuzweleni kwe-electrostatic komkhiqizo ofuna ukuwuvikela kanye namazinga omkhakha.
