Kwimisebenzi yethu yemihla ngemihla kunye nemibuzo yabathengi, sifumanise ukuba kukho imibuzo emininzi malunga -nemigangatho engatshintshiyo ye "anti{1}}ibhodi yesilicone engatshintshiyo" phakathi kwabantu. Ingaba "i-anti{3}}i-static" injani? Yeyiphi imigangatho yovavanyo olugunyazisiweyo? Ziziphi iimfuno ezahlukeneyo kwiimeko ezahlukeneyo zesicelo? Namhlanje, masiyicacise kakuhle.
一, Izalathi ezingundoqo: Ukuxhathisa ngundoqo
Undoqo wesalathisi sokulinganisa -ukusebenza okumileyo kukuxhathisa. Ngokwendlela edlulayo ngoku, sigxila ikakhulu kwiiparamitha ezimbini:
1.I-Surface Resistivity (i-surface Resistivity) : Ukuxhathisa kwesixhobo xa i-current iqukuqela kumphezulu wayo. Iyunithi: Ohm (Ω)
2. Umthamo we-Resistivity (i-volume Resistivity) : ukuxhathisa kwempahla xa ikhoyo idlula kuyo. Iyunithi: Ohm ·cm (Ω·cm).
Kwimathiriyeli enombhobho njengerabha ye-silicone enegwebu, ukumelana nomthamo kudla ngokuba sisalathisi esibaluleke ngakumbi njengoko kunokubonakalisa ngokupheleleyo ukuqhutywa kombane kwento yonke.
2, iMigangatho ePhambili kunye noHlelo lweBanga ngoku.
Akukho mgangatho umanyeneyo udityanisiweyo wokuhlelwa komgangatho wezixhobo ezichasene -nestatic kumazwe ngamazwe. Nangona kunjalo, ezi nkqubo zilandelayo eziphambili kunye nemigangatho zicatshulwa ngokubanzi kwaye zamkelwe:
1. IMigangatho yoMbutho we-ESD (ESDA).- Elona gunya linegunya leNkqubo yokuKhusela i-Electrostatic Imigangatho eyenziwe yi-Electrostatic Discharge Association yase-United States zezona zalathiso zinegunya kwishishini le-elektroniki. Umgangatho wayo we-ANSI/ESD S20.20 uhlela imathiriyeli ibe ngamacandelo amathathu, okubalulekileyo ekuqondeni kwethu -ibakala elingatshintshiyo:
1) Izinto zokuqhuba (I-Conductive) : ukumelana nomphezulu: ngaphantsi kwe-1 x 10⁴ Ω (okt,<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) Izinto zokuchithwa kwe-Static (i-static Dissipative) : ukumelana nomphezulu: 1 x 10⁴ Ω ukuya ku-1 x 10¹¹ Ω umthamo wokumelana nomthamo: 1 x 10⁴ Ω·cm ukuya ku-1 x 10¹¹ Ω·cm iimpawu: eli lelona bakala lixhaphakileyo lebhodi ye-silicone ye-anti{9}! Iyakwazi ukukhupha iintlawulo ezimileyo emhlabeni ngesantya esilawulekayo nesicothayo, inqanda ukuveliswa kwemisinga emikhulu ngephanyazo, kwaye ngaloo ndlela ikhusela ngokukhuselekileyo uninzi lwamalungu e-elektroniki.
3)Imathiriyeli yokugquma: Ukumelana nomphezulu: inkulu kuno okanye ilingana no-1 x 10¹² Ω (okt, Inkulu kuno okanye ilingana ne-1,000,000,000,000 Ω) Ukumelana nomthamo: mkhulu okanye ulingana no-1 x 10¹² Ω·cm umbane Irabha ye-silicone eqhelekileyo iwela kolu didi.
2. Eminye imigangatho eqhelekileyo
I-ASTM D257: Umbutho waseMelika woVavanyo kunye nomgangatho wezinto, eyona ndlela isemgangathweni yovavanyo lokulinganisa ukuxhathisa okuthe ngqo kwangoku okanye ukuqhutywa kwezixhobo zokugquma.
I-IEC 61340: Umgangatho weKomishoni yoMbane weHlabathi, efana nomgangatho we-ESDA, ukwayinkqubo eyaziwayo kwihlabathi jikelele yokhuseleko lombane.
Imigangatho yomkhosi efana ne-MIL-PRF{2}}87893: Baneemfuno ezingqongqo kunye nezithe ngqo ekusebenzeni kwezinto ezichasene ne-static.
Umgangatho ochasayo-umgangatho omileyo we-anti{1}}ibhodi yesilicone engatshintshiyo yogwebu ixhomekeke ikakhulu ekubeni umthamo wayo/umphezulu wokuxhathisa iwela ngaphakathi koluhlu lwe "static dissipation" lwe-10⁴ ukuya 10¹¹ Ω·cm. Loluphi uluhlu oluthe ngqo-olukhethayo luxhomekeke kubuntununtunu be-electrostatic bemveliso ofuna ukuyikhusela kunye nemigangatho yoshishino.
