Muraayadda caadiga ah waa walxo dahaar leh, kuwaas oo noqon kara kuwo gudbiya iyadoo lagu dahaadho filim gudbiye (ITO ama filim FTO) dusha sare. Kani waa muraayad gudbiye ah. Waa mid si indho-furan u iftiimaysa oo leh dhalaal kala duwan. Waxay ku xiran tahay nooca taxanaha muraayadda gudbiye ee dahaarka leh.
Kala duwanaanshahaMuraayadaha dahaarka leh ee ITOwaa 0.33/0.4/0.55/0.7/1.1/1.8/2.2/3mm oo leh cabbirka ugu badan 355.6×406.4mm.
Kala duwanaanshahagalaas dahaarka leh ee FTOwaa 1.1/2.2mm oo leh cabbirka ugu badan 600x1200mm.
Laakiin waa maxay xiriirka ka dhexeeya iska caabinta labajibbaaran iyo iska caabinta iyo socodka?
Guud ahaan, tusmada loo isticmaalo baaritaanka sifooyinka gudbinta ee lakabka filimka gudbinta waa iska caabbinta xaashida, taas oo ay matashoR (ama Rs). Rwaxay la xiriirtaa iska caabinta korantada ee lakabka filimka gudbiya iyo dhumucda lakabka filimka.
Jaantuska,dwaxay matalaysaa dhumucda.
Iska caabbinta lakabka gudbinta xaashida waaR = pL1 (dL2)
Qaacidada,pwaa iska caabinta filimka gudbiyaha.
Lakabka filimka ee la sameeyay,piyodwaxaa loo arki karaa qiimayaal joogto ah.
Marka L1 = L2, waa laba jibbaaran, iyadoon loo eegin cabbirka baloogga, iska caabintu waa qiime joogto ahR=p/d, taas oo ah qeexidda iska caabbinta labajibbaaran. Taasi waa,R=p/d, cutubka Rwaa: ohm/sq.
Waqtigan xaadirka ah, iska caabinta lakabka ITO guud ahaan waa ku saabsan tahay0.0005 Ω.cm, waxaana ugu fiican0.0005 Ω.cm, kaas oo u dhow iska caabinta birta.
Isku-dhafka iska caabinta waa laydhka,σ= 1/p, inta badan ee uu socdo, ayaa uu sii xoogaysanayaa habka loo maro.
Saida Glass ma aha oo kaliya xirfadle ku ah meel galaas ah oo loo habeeyey, laakiin sidoo kale waxay awood u leedahay inay ka caawiso macaamiisha xallinta arrimaha farsamada ee aagga galaaska.
