Dahaarka aluminiumka muraayadda ee nalka Slit
Sharaxaada Alaabta
Muraayadaha noocan oo kale ah ayaa inta badan loo isticmaalaa nalalka jeexjeexan ee dhakhtarka indhaha si ay u bixiyaan sawir cad oo sax ah ee isha bukaanka. Dahaarka aluminiumka ee muraayadda laambad la jeexay wuxuu u shaqeeyaa sidii dusha sare ee milicsiga, taasoo u oggolaanaysa in iftiinka lagu hago xaglo kala duwan iyada oo loo marayo ardayga bukaanka iyo isha.
Daahan aluminium ka difaaca waxa lagu dabaqaa hab loo yaqaan vacuum deposition. Tani waxay ku lug leedahay kuleylinta aluminiumka qolka faakuumka, taasoo keenaysa inuu uumi baxo ka dibna ku ururo dusha muraayadda. Dhumucda dahaarka waa la xakameyn karaa si loo hubiyo muujinta ugu fiican iyo adkeysiga.
Muraayadaha aluminiumka ah ee ilaaliya ayaa laga doorbidaa noocyada kale ee muraayadaha loogu talagalay nalalka jeexan sababtoo ah waxay leeyihiin muuqaal sare, waxay u adkaystaan daxalka iyo xoqidda, wayna fudud yihiin. Dusha sare ee muraayadda waxay u baahan tahay in la ilaaliyo si loo hubiyo waxqabadka ugu fiican, sidaas darteed, waa in taxaddar la sameeyaa si looga fogaado xoqidda ama waxyeello u geysata muraayadda muraayadda inta lagu jiro isticmaalka ama nadiifinta.
Laydhka jeexan ayaa ah qalab baadhitaan oo muhiim ah oo ay isticmaalaan dhakhaatiirta indhaha si ay u baadhaan isha. Laydhka jeexan wuxuu u oggolaanayaa dhakhaatiirta inay baaraan qaybaha kala duwan ee isha, sida cornea, iris, lens, iyo retina. Mid ka mid ah qaybaha muhiimka ah ee nalka dillaacsan waa muraayadda, taas oo loo isticmaalo in lagu bixiyo muuqaal cad oo fiiqan oo isha ah. Muraayadaha aluminium-dahaarka leh ayaa caan ku noqday sannadihii ugu dambeeyay sababtoo ah waxqabadkooda sare ee indhaha iyo adkeysiga.
Muraayada aluminiumku waa muraayad tayo sare leh oo ka samaysan muraayad. Muraayada waxaa lagu dahaadhay lakab khafiif ah oo aluminium ah, taasoo siinaya muraayadda kor u qaadida milicsiga iyo sifooyinka indhaha. Muraayada waxaa loogu talagalay in lagu dhejiyo laambada dillaacsan, halkaas oo ay ka tarjumayso iftiinka iyo sawirada isha. Dahaarka aluminiumka ee muraayadda ayaa bixiya iftiin u dhow oo qumman, hubinta in sawirka ka soo baxa uu yahay mid cad oo dhalaalaya.
Mid ka mid ah sifooyinka muuqda ee muraayadaha aluminiumku waa adkeysigooda. Muraayaddu waxay ka samaysan tahay maaddooyin tayo sare leh oo iska caabiya waxyeelada ka timaadda shooga jirka, xagashada, iyo kiimikooyinka. Muraayada waxaa loogu talagalay in ay u adkeyso dhibaatooyinka isticmaalka maalinlaha ah, taas oo ka dhigaysa mid la isku halleyn karo oo kharash-ool ah oo ka mid ah nalka dillaacsan.
Muraayada aluminium-dahaarka leh ayaa sidoo kale bixisa kala duwanaansho aad u fiican. Milicsiga sare ee muraayadu waxay u ogolaataa dhakhaatiirta indhaha inay si cad u arkaan faahfaahinta indhaha, taas oo sahlaysa in la ogaado cudurrada kala duwan ee indhaha. Iyada oo ay ugu wacan tahay waxqabadkeeda sare ee indhaha, muraayadaha aluminium-ku-daran ayaa noqday qalab lagama maarmaan u ah dhakhaatiirta indhaha ee baadhitaankooda maalinlaha ah iyo daaweynta.
Marka la soo koobo, muraayadda aluminium-ku dahaaran tahay waa qayb muhiim ah oo ka mid ah nalka dillaacsan, taasoo siinaysa dhakhaatiirta indhaha oo leh sawirro indho cad oo fiiqan. Qalabka tayada sare leh ee loo isticmaalo dhismaha muraayadda ayaa ka dhigaya mid la isku halleyn karo oo waara, hubinta in ay u adkeysan karto isticmaalka maalinlaha ah. Wax qabadkeeda sare ee indhaha iyo cimri dhererka dheer ayaa ka dhigaya maalgashi aad u fiican dhaqtar kasta oo indhaha ah oo raadinaya inuu kor u qaado awoodiisa ogaanshaha.
