I roto i a maatau mahi o ia ra me nga patai a nga kaihoko, kua kitea he maha nga paatai mo nga paerewa anti-pateko o "paari pahuka silicone anti-pateko" i waenga i nga tangata. He pehea te "anti-static"? He aha nga paerewa whakamatautau mana? He aha nga whakaritenga rereke mo nga ahuatanga tono rereke? I tenei ra, kia ata whakamaramatia e tatou.
一, Tohu Matua: Ko te aukati te mea matua
Ko te tohu matua mo te ine -mahi pateko he parenga. E ai ki te huarahi e haere ai te naianei, ka aro nui tatou ki nga tawhā e rua:
1.Parenga Mata (Resistivity Surface) : te parenga o tetahi rawa ina rere te ia i runga i tona mata. Waeine: Ohm (Ω)
2. Rōrahi Rōrahi (volume Resistivity) : te ātete o te rawa ina rere ana te au. Waeine: Ohm ·cm (Ω·cm).
Mo nga rawa maiengi penei i te rapa silicone pahuka i te nuinga o te waa, he tohu tino nui te aukati rōrahi na te mea ka taea e ia te whakaata matawhānui i te kawe hiko o te rauemi.
2, Paerewa Auraki me te Whakarōpū Kōeke I tēnei wā.
Karekau he tino paerewa kotahi mo te whakarōpū auroro o -matea pateko o te ao. Heoi, ko nga punaha me nga paerewa auraki e whai ake nei ka whakahuahia me te whakamahi:
1. ESD Association (ESDA) Paerewa- Te Pūnaha Tiaki Electrostatic tino whai mana Ko nga paerewa i hangaia e te Electrostatic Discharge Association o te United States ko nga tohutoro whai mana i roto i te ahumahi hiko. Ko tana paerewa ANSI/ESD S20.20 ka whakarōpū i nga rawa ki nga waahanga e toru, he mea tino nui mo to maatau mohio ki te koeke anti-pateko:
1)Raumea kawe (Conductive): parenga mata: iti iho i te 1 x 10⁴ Ω (arā,<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)Rauemi tohanga pateko (Pateko Dissipative): parenga mata: 1 x 10⁴ Ω ki te 1 x 10¹¹ Ω rōrahi parenga: 1 x 10⁴ Ω·cm ki te 1 x 10¹¹ Ω·cm ngā āhuatanga: koinei te kōeke tino noa o te papa pateko o te silicone - Ka taea e ia te tuku i nga utu pateko ki te whenua i runga i te tere tere me te puhoi, te karo i te whakatipuranga o nga au nunui inamata, na reira ka tiakina te nuinga o nga waahanga hiko.
3)Raumea whakaahuru: Te parenga o te mata: nui ake, e rite ana ranei ki te 1 x 10¹² Ω (arā, Nui ake i te rite ranei ki te 1,000,000,000,000 Ω) Rōrahi parenga: nui ake, e rite ana ranei ki te 1 x 10¹² Ω·cm Ngā Āhuatanga: Ko te hiko hiko e kore e taea te rere me te pahekeheke. Ka taka te rapa silicone noa ki tenei waahanga.
2. Ētahi atu paerewa noa
ASTM D257: American Society for Testing and Materials paerewa, koinei te tikanga whakamatautau mo te ine i te aukati tika o naianei, te whakahaere ranei o nga rawa whakamarumaru.
IEC 61340: He paerewa Komihana Electrotechnical International, he rite ki te paerewa ESDA, he punaha paerewa e mohiotia ana mo te tiaki hiko.
Nga paerewa hoia penei i te MIL-PRF-87893: He tino kaha ake, he whakaritenga motuhake hoki mo te mahi o nga rawa anti-static.
Ko te paerewa anti-pateko mo -pateko pateko papa pahuka i te nuinga o te mea kei te taka tona rōrahi/te parenga mata ki roto i te awhe "torere pateko" 10⁴ ki te 10¹¹ Ω·cm. Ko tehea awhe iti-tau e whiriwhiri ka whakawhirinaki ki te tairongo hiko o te hua e hiahia ana koe ki te tiaki me nga paerewa ahumahi.
