Muraayada qaadka aluminium ee iftiinka slit
Sharraxaadda Wax soo saarka
Muraayadaha noocan ah waxaa badanaa loo isticmaalaa laambadaha spit ee indhaha si loo bixiyo sawir cad oo sax ah oo isha bukaanka. Daboolida aluminium ee lagu daboolay muraayad slit ah wuxuu u shaqeeyaa sidii dusha sare ee milicsiga ah, taasoo u oggolaaneysa in iftiinka lagu hago xaglo kala duwan oo loo maro ardayga bukaanka iyo isha.
Darajada aluminiumka ee difaaca waxaa lagu dabaqayaa hanaan loo yaqaan 'vapuum'. Tani waxay ku lug leedahay kuleylka aluminium ee aluminiumka qolka faaruq ah, taasoo keenaysa in ay uumi baxto ka dibna ay udhacdo dusha sare ee muraayadda. Dhumucduhu waxay la xakameyn kartaa si loo hubiyo in milicsiga ugu fiican iyo cimri dherer.
Muraayadaha aluminium-ka ah ayaa laga door bidaa noocyo kale oo muraayadaha ah oo loogu talagalay nalalka slit-ka sababta oo ah waxay leeyihiin fal-celin sare, waxay u adkaysanayaan hudheelka iyo abbaaraha, oo khafiifka ah. Dusha sare ee muraayadda ee muraayadda waxay u baahan tahay in la ilaaliyo si loo hubiyo waxqabadka ugu habboon, sidaa darteed, waa in taxaddar la sameeyaa si looga fogaado xoqida ama waxyeelada udhacaya muraayadda dusha lagu jiro ama nadiifinta.
Nalalka slit waa aalad cudur ah oo muhiim ah oo loo isticmaalo cilmiga dhakhaatiirta indhaha ee lagu baaro indhaha. Nalal slit ah ayaa u oggolaanaya dhakhaatiirta inay baaraan qaybo kala duwan oo isha ah, sida Corria, Iris, lens, iyo retina. Mid ka mid ah qaybaha muhiimka ah ee nalka slit waa muraayadda, kaas oo loo isticmaalo in lagu bixiyo muuqaalka cad ee isha iyo isha ee isha. Muraayadaha isku-darka ah ee alwaaxa lagu soo rogay sanadihii ugu dambeeyay awgeed sababtoo ah waxqabadka indhaha ee indhaha iyo cimri dhererkooda.
Muraayada aluminized waa muraayad tayo sare leh oo laga sameeyay galaas. Muraayada waxaa lagu dahaadhay lakab khafiif ah oo aluminium ah, siinta muraayadda loo wanaajiyo milicsiga iyo guryaha indhaha. Muraayada waxaa loogu talagalay in lagu meeleeyo nalka slit, halkaas oo ay ka tarjunto iftiinka iyo sawirrada isha. Qeybta aluminium ee muraayadda ee muraayadda waxay bixisaa milicsiga-ku-meel-gaarka ah ee iftiinka, hubinta in sawirka ka dhalanaya ay tahay mid dhalaalaya oo dhalaalaya.
Mid ka mid ah astaamaha muujinta ee muraayadaha aluminied ah waa midnimadooda. Mirrorku wuxuu ka samaysan yahay qalab tayo sare leh oo iska caabiya waxyeelada ka timaada naxdinta jirka, xoqida, iyo kiimikooyinka. Muraayada waxaa loogu talagalay in lagu hor istaago qashinka loo isticmaalo maalin kasta, taasoo ka dhigeysa qayb la isku halleyn karo oo qiimo wax ku ool ah oo ka mid ah laambada slit.
Mirror-ka qafiif ah ee aluminium sidoo kale wuxuu bixiyaa isbarbardhig heer sare ah. Ciqaabta sare ee muraayadda ayaa u oggolaaneysa dhakhaatiirta indhaha si ay u arkaan faahfaahinta indhaha si muuqata, taas oo u sahlaysa in lagu garto cudurrada indhaha oo kala duwan. Sababo la xiriira waxqabadka indhaha ee ugu sareeya, muraayadaha alwaaxa ah ayaa noqday aalad muhiim u ah cilmiga dhakhaatiirta indhaha ee cilmiga caleemu-yaqaankooda iyo daaweynta.
Marka la soo koobo, muraayadda aluminiumka waa qayb muhiim ah oo ka mid ah laambada slit, oo bixiya dhakhaatiirta indhaha oo leh sawirro indhaha oo fiiqan oo fiiqan. Qalabka tayada sare leh ee loo isticmaalo dhismaha muraayadda ayaa ka dhigaya mid la isku halleyn karo oo waara, hubinta inay u adkeysan karto khilaafyada isticmaalka maalin kasta. Waxqabadka indhaha ee ugu sarreeya iyo cimri dheer ee ugu dambeeya ayaa ka dhigaysa maalgashi heer sare ah oo loogu talagalay wax-maalgelin kasta oo indhaha ah oo raadinaya kor u qaadida awoodooda ogaanshaha cudurka.
