Waa maxay shuruudaha deegaanka ee xaashida birta ah ee midabaysan ee aluminium dahaarka leh ee daabacan?

Waa maxay shuruudaha deegaanka ee xaashida birta ah ee midabaysan?

Shuruudaha deegaanka ee xaashida birta ah ee midabaysan ayaa diiradda saaraya xakamaynta qiiqa VOC (Volatile Organic Compound), xaddidaadda biraha culus ee dahaarka (sida rasaasta, cadmium, iyo chromium hexavalent), dib-u-warshadaynta labadaba substrate-ka iyo dahaarka, iyo maareynta tamarta iyo qashinka inta lagu jiro habka wax soo saarka. Dhinacyadan waxaa ka mid ah, dhimista VOC hadda waa aagga sida adag loo maamulay waxayna culayska ugu weyn saartaa shirkadaha si ay u fuliyaan tallaabooyinka sixitaanka.

Waraaqaha birta ah ee midabka leh (sidoo kale loo yaqaan xaashida birta midabka) waa walxo isku dhafan oo la soo saaray iyadoo la isticmaalayo birta qabow-duuban, birta galvanized, ama aluminium go'yaal substrate ahaan. Daaweynta dusha ka dib, dahaarka organic ayaa lagu dabaqaa habka duubista. Agabkaan waxaa si weyn looga faa'ideysanayaa qeybaha sida dhismaha, qalabka guriga, iyo alaabta guriga. Si kastaba ha ahaatee, dahaarka dhaqameed ee ku salaysan dareeraha waxay sii daayaan tiro badan oo VOCs ah (ay ku jiraan benzene, toluene, iyo xylene) inta lagu jiro habka codsiga waxayna ka kooban yihiin biraha culus ee waxyeellada leh-sida rasaasta iyo cadmium-taas oo ka qaybqaata wasakhowga jawiga iyo keenista khataro caafimaad.

Heerarka Deegaanka ee Dahaarka iyo Dhammaadka

Xaddidaadaha Birta Culus: U hoggaansanaanta Awaamiirta RoHS ee EU waa qasab, una baahan in si adag loo xakameeyo waxa ku jira walxaha sida rasaasta (Pb), cadmium (Cd), iyo chromium hexavalent (Cr⁶⁺). Heerkan ayaa durba si weyn loogu dhaqan geliyey xaashida midabada leh ee loo isticmaalo qalabka guriga.

Nuxurka VOC: In kasta oo heerarka qaranku aanay hadda ku soo rogin xad sare oo midaysan nuxurka VOC ee dahaarka laftooda, waxay amar ku bixinayaan in shirkaduhu ay gaadhaan u hoggaansanaanta heerarka qiiqa iyada oo loo marayo tillaabooyinka daawaynta dhammaadka-tubaabka (sida gubi heerkul sare).

Shahaadada Deegaanka: Shirkadaha waxaa lagu dhiirigelinayaa inay codsadaan shahaadada "Alaabta Cagaaran"; kuwa hela shahaadadaas waxay u qalmi karaan dhiirigelinta cashuuraha.

Shuruudaha Deegaanka ee Hannaanka Wax Soo Saarka

Daawaynta Gaasta Qashinka: Rakibaadda qalabka daawaynta ee VOC oo tayo sare leh (sida gubiyaasha tooska ah) waa qasab si loo hubiyo in walxaha gubanaya ay ka kooban yihiin CO₂ iyo biyo oo keliya, si meesha looga saaro qiiqa aan la oggolayn ama shilalka ah.

Biyaha wasakhda ah iyo qashinka adag: Marxaladaha daawaynta ka hor-sida nadiifinta alkaline-ka-waa in lagu qalabeeyaa tas-hiilaadka daaweynta biyaha wasakhda ah ee u dhigma. Wasakhda rinjiga qashinka waxay u baahan tahay qashin gaar ah sida qashinka khatarta ah waana inaan si aan kala sooc lahayn loo daadin.

Waxtarka Tamarta: Heerarka daaweynta iyo dubista geeddi-socodka waa in lagu daraa teknoolojiyadda tamarta-badbaadinta (sida hababka soo kabashada kulaylka qashinka) si loo yareeyo qiiqa kaarboonka halbeeg kasta oo wax soo saar ah.

Dariiqooyin Kale iyo Isbeddellada Cagaaran

Dahaarka biyaha ku salaysan: Iyadoo deegaan ahaan saaxiibtinimo, dahaarkani hadda ma laha iska caabin ku filan daxalka iyo kulaylka caabbinta si ay ugu adeegaan sida buuxda ee daahan ku salaysan dareere.

Hababka Lamination: Ka soo jiidashada dhiirigelinta tignoolajiyada birta dahaadhay ee Jabbaan, habkani wuxuu beddelaa dahaarka dareeraha dhaqameed ee filimada polymerka. Habkani waxa uu sahlayaa habka wax soo saarka ee leh "eber VOCs iyo eber biyaha wasakhda ah" waxaana loo arkaa in uu yahay xalka cagaaran ee ugu dambeeya ee warshadaha. Casriyeynta Substrate-ka: Kor-u-qaadista isticmaalka substrate-ka aadka u adkaysiga daxalka-sida aluminium-zinc-kulul-kulul (55% Al-Zn)-si loo yareeyo dhumucda dahaarka iyo isticmaalka walxaha, taaso si dadban hoos ugu dhigaysa culayska deegaanka.

Furaha lagu hubinayo u hoggaansanaanta deegaanka ee xaashida birta ah ee horay loo rinjiyeeyay waxay hadda ku jirtaa:

Doorashada dahaarka-shahaadada ee RoHS;

Gelinaya qalabka daaweynta dhamaadka-tubaabka ee waxtarka sare leh ee VOCs;

Sahaminta hababka-yaraynta ilaha-sida lamination filimka-si loo yareeyo wasakhowga isha.
