Alumina Plate Transparent & Tansparent Alumina Board waa walxo dhoobo ah oo wax qabad sare leh oo lagu yaqaanay caddaynta indhaha ee gaarka ah, xoogga farsamada, iyo xasiloonida kulaylka. Qalabkan horumarsan, oo sidoo kale loo yaqaanno saxan aluminium hufan ah ama xaashida aluminium indhaha ah, ayaa lagu soo saaray iyadoo la adeegsanayo farsamooyin gaar ah oo u oggolaanaya inay gudbiso iftiinka iyadoo la ilaalinayo sharafta qaab dhismeedka aluminium oxide dhaqameed. Saxanka hufan ee Al2O3 ayaa si weyn loogu isticmaalaa warshadaha, sayniska, iyo codsiyada teknoolajiyada halkaas oo labadaba adkeysiga iyo daahfurnaanta ay yihiin lagama maarmaan.
Alaabta waxaa loo habeeyay si ay u bixiso isku-dar gaar ah oo hanti ah oo ka dhigaya mid ku habboon deegaan ballaaran oo baahi badan. Waxay bixisaa iska caabin heer sare ah oo kulka, daxalka, iyo xirashada, taasoo ka dhigaysa mid ku habboon in loo isticmaalo xaaladaha adag. Intaa waxaa dheer, alaabteeda indhaha waxay awood u siineysaa inay u shaqeyso sidii daaqad cad ama qayb ka mid ah nidaamyada indhaha ee kala duwan, sida aaladaha laysarka, dareemayaasha infrared, iyo aaladaha saxda ah. Xaashiyaha aluminium ee hufan ayaa inta badan laga door bidaa dhalooyinka caadiga ah ama balaastigga sababtoo ah xooggeeda sare iyo kalsoonida muddada dheer.
Tilmaamaha muhiimka ah ee saxan aluminium ee hufan waxaa ka mid ah hufnaanta sare ee iftiinka kala duwan, oo ay ku jiraan mawjadaha dhaadheer ee muuqda iyo kuwa dhow-infrared. Waxaa lagu heli karaa dhumucyo iyo cabbirro kala duwan si loo buuxiyo shuruudaha codsiga gaarka ah. Xuubka hoose ee maaddadu waxay hubisaa kala firdhisanaanta iftiinka ugu yar, taasoo keentay soo saarid muuqaal ah oo cad oo joogto ah. Dusha sare ee aan daloolka lahayn ayaa sidoo kale ka dhigaysa mid u adkaysata weerarka kiimikada oo ay fududahay in la nadiifiyo, iyada oo sii wanaajinaysa ku habboonaanta jawiga xasaasiga ah.
Lagu soo saaray hab saxan saxan, saxanka Al2O3 ee daah-furan waxaa loogu talagalay in lagu ilaaliyo wax qabadkeeda indhaha xitaa heerkul aad u daran. Tani waxay ka dhigaysaa doorasho ku habboon codsiyada hawada hawada, difaaca, iyo goobaha warshadaha heerkulka sare. Awoodda maaddada u adkeysiga culeyska farsamada iyada oo aan la carqaladeynin daahfurnaanta ayaa ka dhigaysa noocyada kale ee dhoobada hufan. Haddii loo isticmaalo sida daboolka ilaalinta, daaqadda qaybaha indhaha, ama qayb dhismeed, saxan alumina ah ee hufan wuxuu bixiyaa xal la isku halayn karo oo waara.
Alaabtani waxay ka helaysaa codsi warshado kala duwan, oo ay ku jiraan laakiin aan ku xaddidnayn injineernimada indhaha, wax-soo-saarka semiconductor, sawir-caafimaad, iyo nidaamyada iftiinka sare. Injineernimada indhaha, saxanka aluminium ee hufan wuxuu u adeegaa sidii qayb muhiim ah oo ka mid ah aaladaha u baahan caddayn iyo xoog labadaba. Warshadaha semiconductor-ka, waxaa loo isticmaalaa sidii substrate loogu talagalay hababka saxda ah ee saxda ah. Sawirka caafimaadka, waxay u shaqeysaa sidii caqabad cad oo loogu talagalay raajada iyo qalabka shucaaca. Nidaamyada nalalka, waxaa lagu dhex dari karaa laambadaha dareeraha ah ee xoogga badan ama shirarka LED si ay u bixiyaan iftiin hufan.
Isticmaalayaasha ku daray xaashidan aluminium ee daah-furnaanta ah mashruucyadooda waxay inta badan muujiyaan isku halaynta iyo waxqabadkeeda. Dad badan ayaa soo wariyay in ay ka wanaagsan tahay agabka dhaqanka marka loo eego cimri dherer iyo caddayn. Isticmaalayaasha qaarkood waxay xusaan in caabbinta walxaha ee xagashada iyo saamaynta ay ka dhigayso mid si gaar ah faa'iido u leh meelaha gaadiidka-sare ama cadaadiska sareeyo. Kuwo kale waxay qadarinayaan sahlanaanta lagu farsamayn karo oo lagu habeyn karo si ay ugu habboonaato baahiyaha naqshadaynta gaarka ah. Guud ahaan, jawaab celinta waxay ka tarjumaysaa ku qanacsanaanta xoogga leh ee shaqada iyo tayada alaabta.
Su'aalaha caadiga ah ee ku saabsan saxankan aluminium ee daah-furan waxay inta badan ku wareegaan cimrigiisa, waxqabadka indhaha, iyo la jaanqaadka agabka kale. Isticmaalayaashu waxay had iyo jeer weydiiyaan in la gooyn karo ama la qaabayn karo iyada oo aan la carqaladeynin daahfurnaanteeda. Jawaabtu waa haa, maadaama walxaha lagu farsamayn karo iyadoo la isticmaalayo qalab caadi ah, inkastoo ay tahay in laga taxadaro si looga fogaado dildilaaca ama jajabinta. Weydiinta kale ee caanka ah waxay ku saabsan tahay iska caabbinta isbeddelka heerkulka. Saxanka hufan ee Al2O3 waxaa lagu yaqaanaa xasiloonida kulaylka, taas oo ka dhigaysa mid ku habboon in loo isticmaalo jawi heerkulkiisu sarreeyo iyo mid hooseeya. Isticmaalayaasha qaar ayaa sidoo kale wax ka weydiiya ku habboonaanta isticmaalka vacuum ama xaaladaha cadaadiska sarreeya, taas oo ay si wax ku ool ah u maareyn karto sababtoo ah qaab-dhismeedkeeda cufan iyo porosity hooseeya.
