Hawlgalkayaga maalinlaha ah iyo weydiimaha macmiilka, waxaanu ku ogaanay inay jiraan su'aalo badan oo ku saabsan ka-hortagga heerarka {{1}static silicone foam board" ee dadka dhexdooda. Sidee buu u yahay "anti-static"? Waa maxay heerarka imtixaanka awood? Waa maxay shuruudaha kala duwan ee xaaladaha kala duwan ee codsiga? Maanta, aan si fiican u caddayno.
一, Tilmaamayaasha Muhiimka ah: Iska caabintu waa furaha
Tilmaamaha xudunta u ah cabbiraadda waxqabadka lidka ku ah - waa iska caabin. Marka loo eego dariiqa uu hadda maraayo, waxaanu inta badan diirada saarnaa laba qaybood:
1.Dusha iska caabbinta (dulka iska caabinta): caabbinta walax marka uu hadda socdo ooggiisa. Cutubka: Ohm (Ω)
2. Cadaadiska Mugga (Volume Resistivity): caabbinta walxaha marka hadda uu dhex maro. Cutubka: Ohm ·cm (Ω·cm).
Qalabka dabada leh sida caag silikoon xumbo leh, iska caabbinta mugga inta badan waa tilmaame aad muhiim u ah maadaama ay si buuxda u muujin karto guud ahaan korantada walxaha.
2, Heerarka Guud iyo Kala Soocida Fasalka Hadda.
Ma jiro halbeeg gabi ahaanba midaysan oo loogu talagalay kala soocida darajada agabka lidka ku ah{0} caalamka. Si kastaba ha ahaatee, nidaamyada iyo halbeegyada guud ee soo socda ayaa si weyn loo soo xigtay oo la qaatay:
1. Heerarka Ururka ESD (ESDA).- Nidaamka Ilaalinta Electrostatic ee ugu awooda badan Heerarka ay dajiyeen Ururka Siinta Electrostatic ee Maraykanka ayaa ah tixraacyada ugu awooda badan warshadaha elegtarooniga. Heerkeeda ANSI/ESD S20.20 waxay agabka u kala saartaa saddex qaybood, taas oo muhiim u ah fahamkayaga darajada lidka ku ah{3}}:
1) Alaabaha wax-qabadka (wax-qabadka): iska caabbinta dusha sare: in ka yar 1 x 10⁴ Ω (ie,<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) Walxaha kala daadsanaanta joogtada ah (static Dissipative): iska caabin dusha sare: 1 x 10⁴ Ω ilaa 1 x 10¹¹ Ω caabbinta mugga: 1 x 10⁴ Ω · cm ilaa 1 x 10¹¹ Ω·cm sifooyinka: tani waa heerka ugu caansan ee bodhka foamtic-ka{9}. Waxay ku soo dayn kartaa kharashyada taagan dhulka si xawli ah oo la kontarooli karo oo yara gaabis ah, iyada oo ka fogaanaysa abuuritaanka mawjadaha waaweyn ee degdegga ah, oo sidaas awgeed si badbaado leh u ilaalinaysa inta badan qaybaha elektaroonigga ah.
3) Alaabta dahaarka: Iska caabbinta dusha sare: ka weyn ama le'eg 1 x 10¹² Ω (ie, Ka weyn ama la mid ah 1,000,000,000,000 Ω) caabbinta mugga: ka weyn ama la mid ah 1 x 10¹² Ω·cm Astaamaha: Kharash korontodu ma urursan karo. Caadiga silikoonka caadiga ah wuxuu ku dhacaa qaybtan.
2. Heerarka kale ee caadiga ah
ASTM D257: Heerka Bulshada Mareykanka ee Imtixaanka iyo Qalabka, kaas oo ah habka tijaabada caadiga ah ee lagu cabbirayo iska caabbinta tooska ah ee hadda ama hab-dhaqanka agabka dahaarka.
IEC 61340: Heerka komishanka farsamada caalamiga ah, oo la mid ah heerka ESDA, sidoo kale waa nidaam heer caalami ah oo la aqoonsan yahay oo loogu talagalay ilaalinta korantada.
Heerarka militariga sida MIL{{0}PRF-87893: Waxay leeyihiin shuruudo aad u adag oo gaar ah oo loogu talagalay waxqabadka agabyada ka hortagga ah.
Heerarka lidka{{0}static ee looxyada xumbo silikoon ee taagan inta badan waxa ay ku xidhan tahay in mugga/iska caabbinta dushiisa ay ku dhacdo inta u dhaxaysa 10⁴ ilaa 10¹¹ Ω·cm. Qaybta hoose ee gaarka ah ee - kala duwan ee aad doorato waxay kuxirantahay dareenka elektrostatic ee alaabta aad rabto inaad ilaaliso iyo heerarka warshadaha.
