Daraasad qoto dheer oo ku saabsan Xiriirka ka dhexeeya Halabuurka iyo Waxqabadka Gariiradda Birta Galvalume

Beeraha sida dhismaha darbiyada daahyada, guryaha qalabka, iyo biraha sawir-qaadista, gariiradaha birta galvalume ayaa si tartiib tartiib ah u beddelaya gariiradaha birta galvalume ee dhaqameed iyagoo ah doorashada ugu weyn sababtoo ah faa'iidooyinkooda laba geesoodka ah ee iska caabbinta daxalka iyo waxtarka kharashka. Hadday tahay Qiimaha Gariirada Birta Galvalume, tixgelin muhiim ah oo ku saabsan soo iibsiga injineernimada, amaASTM A792 Galvalumeqeexitaan si cad loogu qeexay heerarka wax soo saarka, kala duwanaanshaha waxqabadka asaasiga ah wuxuu ka yimaadaa xakamaynta saxda ah ee halabuurka. Maanta, waxaan ku bilaabi doonnaa falanqaynta halabuurka si aan u furfurno sirta waxqabadka ee gariiradaha birta galvalume (oo ay ku jiraan Galvalume Roll, Steel Coil Galvalume, iwm.).
I. Falanqaynta Halabuurka Aasaasiga ah ee Gariiradda Birta Galvalume
Waxqabadka gariiradaha birta galvalume waxaa lagu go'aamiyaa labadaba "walxaha saldhigga ah" iyo "dahaarka." Saamiyada qaybaha kala duwan waxay si toos ah u saameeyaan xaaladaha khuseeya ee badeecada kama dambaysta ah. Tusaale ahaan, naqshadaynta halabuurka ee Galvalume Steel Coil Az150, oo u baahan iska caabinta daxalka sare, ayaa si weyn uga duwan kan Galvalume Coil ee caadiga ah.
1. Halabuurka Dahaarka: "Saamaynta Dahabka" ee Aluminium, Zinc, iyo Silikoon

Dahaarka aluminium-zinc ma aha bir keliya, laakiin waa nidaam isku-dhafan oo ka kooban aluminium (55%), zinc (43.5%), iyo silicon (1.5%). Saamigani waa xalka ugu habboon ee la xaqiijiyay iyada oo loo marayo ku-dhaqanka muddada dheer:
* Aluminium (Al): "Udub dhexaadka u adkaysta daxalka". Aluminiumku wuxuu sameeyaa filim oksaydh oo cufan oo Al₂O₃ ah oo ku yaal dusha sare ee gariiradda birta, kaas oo iska caabin kara daxalka ka yimaada deegaannada adag sida roobka aashitada iyo buufinta milixda. Tani waa sababta ugu weyn ee gariiradaha birta ah ee aluminium-zinc-ga lagu dahaadhay ay u leeyihiin iska caabin daxalka 3-5 jeer ka badan gariiradaha birta galvanized ee caadiga ah;
* Zinc (Zn): Wuxuu ciyaaraa doorka "ilaalinta anode-ka allabaryada ah." Marka dahaarka la xoqo, zinc wuxuu si doorbid leh ula falgalaa oksijiin si looga hortago in birta salka ahi miridhku soo baxo. Isla mar ahaantaana, joogitaanka zinc-ku wuxuu sidoo kale hagaajin karaa dabacsanaanta dahaarka, taasoo u sahlaysa Galvalume Roll inuu leexdo oo shaabadeeyo;
* Silicon (Si): Waxay xallisaa dhibaatada "dhejinta dahaarka". Silicon wuxuu joojin karaa falcelinta u dhaxaysa aluminiumka iyo birta si uu u sameeyo iskudhisyo Fe-Al ah oo jilicsan oo adag, taasoo yaraynaysa khatarta ah in dahaarka diirmo. Saamaynta xasilloonida ee siliconku waxay si gaar ah muhiim ugu tahay Galvalume Steel Coil Az150 oo qaro weyn (AZ150 waxay u taagan tahay 150g oo miisaan dahaar ah halkii mitir laba jibbaaran).
2. Halabuurka Substrate-ka: "Dammaanadda Aasaasiga ah" ee Birta Kaarboon Yar

Substrate-kagariiradaha birta galvalumeinta badan waa bir kaarboon yar (kaarboon ≤0.12%), oo lagu kabo xaddi yar oo manganese ah (0.3-0.6%) iyo fosfooraska (≤0.045%): Kaarboon (C): Kaarboon xad dhaaf ah ayaa ka dhigi doonta substrate-ka mid aad u adag, taasoo ka dhigaysa mid u nugul dildilaaca inta lagu jiro farsamaynta; xaddi aad u hooseeya ayaa yareyn doona xoogga gariiradda birta. Sidaa darteed, kaarboonka ku jira birta kaarboon yar waa in si adag loo xakameeyaa gudaha "isku dheelitirka xoogga iyo habaynta"; Manganese (Mn): Xaddi yar oo manganese ah ayaa hagaajin kara xoogga wax soo saarka ee substrate-ka iyada oo aan si weyn u saameynayn isku-xidhka, taasoo ka dhigaysa mid ku habboon codsiyada culeyska qaada (sida galvalume bir ah oo bir ah oo loogu talagalay biraha sawir-qaadaha); Fosfooraska (P): Fosfooraska wuxuu kordhiyaa jilicsanaanta birta, sidaa darteed maaddada fosfooraska ku jirta substrate-ka waa in si adag loo xaddidaa, taas oo sidoo kale ah mid ka mid ah tilmaamayaasha si cad loogu qeexay heerka ASTM A792 Galvalume.
II. Xiriirka ka dhexeeya Halabuurka iyo Astaamaha Waxqabadka Muhiimka ah Fahmidda halabuurka waxay noo ogolaanaysaa inaan si cad u aragno sababta qaar ka mid ahGalvalume gariiradahawaxay ku habboon yihiin dhismaha bannaanka halka kuwa kalena ay ku habboon yihiin dahaarka qalabka - nuxurka wuxuu ku jiraa kala duwanaanshaha waxqabadka ee ka dhasha hagaajinta halabuurka.

1. Iska caabbinta daxalka: Waxyaabaha Aluminiumku ka kooban yahay waxay go'aamiyaan "Heerka Ilaalinta" Iska caabbinta daxalka waa tartanka ugu muhiimsan eeduubabka galvalume, xiriirkeeda ku saabsan halabuurka ayaa si gaar ah toos u ah: Marka maaddada aluminium ee dahaarka ay ka korto 50% ilaa 55%, cufnaanta filimka oksaydhka Al₂O₃ si weyn ayay u soo hagaagtaa. Deegaannada lagu buufiyo milixda ee xeebta, waqtiga daxalka ee gariiradda birta ah waxaa laga dheereyn karaa 10 sano ilaa in ka badan 20 sano. Haddii maaddada silikoonku ka hooseyso 1%, waxay horseedi doontaa hoos u dhac ku yimaada isku-xidhka u dhexeeya dahaarka iyo substrate-ka, taasoo ka dhigaysa dahaarka mid u nugul inuu ku dhaco finan tijaabooyinka buufinta milixda; haddii ay ka sarreyso 2%, waxay kordhin doontaa jilicsanaanta dahaarka, taasoo yareynaysa cimriga iska caabbinta daxalka. Tani sidoo kale waa sababta Galvalume Steel Coil AZ150 uu u leeyahay iska caabbinta daxalka oo ka xoog badan AZ100 (dahaarka 100g halkii mitir laba jibbaaran) - ma aha oo kaliya in dahaarka uu ka dhumuc weyn yahay, laakiin saamiga aluminium-zinc-silicon sidoo kale si fiican ayuu ugu habboon yahay shuruudaha ilaalinta sare.
2. Sifooyinka Farsamada: Halabuurka Substrate-ka ayaa xukuma "Xoogga iyo Habaynta"
Xoog: Korodh kasta oo 0.1% ah oo ku yimaada maaddada manganese ee substrate-ka, xoogga wax-soo-saarka ee gariiradda birta ah ayaa kordhi kara 5-8 MPa. Sidaa darteed, gariiradda birta Galvalume ee loo isticmaalo codsiyada culeyska qaada, maaddada manganese waxaa lagu xakameeyaa 0.5-0.6%.
Habayn: Codsiyada u baahan shaambad adag, sida qalabka, substrates leh kaarboon ≤0.1% ayaa la doortaa, halka siliconka dahaarka la dhimo ilaa qiyaastii 1.5% si looga hortago dildilaaca dahaarka inta lagu jiro shaambadaynta. 3. Iska caabinta Heerkulka Sare: Faa'iidada Aluminium ee "Xasiloonida Heerkulka Sare"
Barta dhalaalka ee aluminiumka (660℃) aad ayay uga sarreysaa tan zinc (419℃), sidaa darteed, iska caabbinta heerkulka sare ee gariiradaha birta zinc ee aluminiumka ah ayaa aad uga sarreysa kan gariiradaha birta galvanized:
Deegaannada ka hooseeya 200℃ (sida dahaarka foornada), waxqabadka dahaarka waa mid deggan;
Xitaa heerkulka muddada gaaban ee sarreeya ee 300℃, filimka Al₂O₃ wuxuu ka hortagi karaa oksaydhka dahaarka, waana sababta ugu weyn ee Galvalume Roll ugu habboon tahay qiiqa iyo dahaarka tuubooyinka heerkulka sare leh.

III. Xiriirka ka dhexeeya Halabuurka, Waxqabadka, iyo Qiimaha Gariiradda Birta Galvalume

Dad badan ayaa isweydiiya inta lagu jiro wax iibsiga: Maxay farqiga qiimaha ee Galvalume Coil ee isla qeexitaannada ah u gaari karaan 100-200 RMB/tan? Asal ahaan, farqiga qiimaha wuxuu ka tarjumayaa qiimaha qaybaha: Kharashka dahaarka: Qiimaha suuqa ee aluminiumku waa 2-3 jeer ka badan zinc. Sidaa darteed, heerka sare ee aluminiumka ee dahaarka (tusaale ahaan, AZ150 marka la barbar dhigo AZ90), qiimaha sare ee qiimaha, iyo qiimaha sare ee Galvalume Steel Coil. Qiimaha agabka aasaasiga ah: Inta uu ka sarreeyo heerka manganese iyo heerka hoose ee fosfooraska ee birta kaarboon-yar, qiimaha sare ee dhalaalinta ayaa sarreeya, qiimaha sare ee u dhigma ee Galvalume Steel Coil. Qiimaha caadiga ah: Alaabooyinka u hoggaansan heerka ASTM A792 Galvalume waxay leeyihiin xakameyn dulqaad qaybaha oo adag (tusaale ahaan, leexashada nuxurka aluminiumka ≤ ±1%), heerka qashinka oo sarreeya inta lagu jiro wax soo saarka, iyo qiimaha 5-8% ka sarreeya alaabada aan caadiga ahayn. IV. Kiiska Codsiga ee Waxtarka leh: Muhiimadda Xulashada Halabuurka

Mashruuc dhisme xeebeed ayaa isbarbardhigay laba nooc oo gariiradaha birta galvalume ah: Galvalume Coil Caadi ah (50% aluminium, 1% silicon): Daxalka maxalliga ah ayaa soo muuqday ka dib 3 sano oo la isticmaalay; Galvalume Steel Coil Az150 (55% aluminium, 1.5% silicon), oo u hoggaansan ASTM A792: Ma jirin daxal muhiim ah ka dib 5 sano oo la isticmaalay, mana jirin wax isbeddel ah intii lagu jiray saameynta duufaanta (sifooyinka farsamada ee sare). Mashruucu wuxuu ugu dambeyntii doortay kan dambe. Inkasta oo qiimaha bilowga ah ee Galvalume Steel Coil uu ahaa 150 RMB/tan ka sarreeya, cimriga adeegga waxaa lagu kordhiyay in ka badan 10 sano, taasoo keentay kharash guud oo muddo dheer ah oo hooseeya.

Gunaanad: Naqshadaynta isku-dhafka gariiradaha birta galvalume waa hab "shuruudo isku mid ah": AZ150 (aluminium sare, silicon sare) ayaa loo doortay iska caabbinta daxalka sare; silicon hooseeya, substrate-ka kaarboon hooseeya ayaa loo doortay habaynta adag; badeecadaha caadiga ah ee ASTM A792 waxaa loo doortay mashaariicda dhoofinta. Iyadoo mustaqbalka la horumarinayo warshadaha tamarta ee photovoltaic iyo kuwa cusub, hagaajinta isku-dhafka (sida ku darista xaddi raad ah oo walxo dhul naadir ah si loo hagaajiyo iska caabbinta daxalka) waxay noqon doontaa jiho horumarineed oo muhiim ah oo loogu talagalay gariiradaha birta zinc ee aluminium, taasoo sii ballaarinaysa xuduudahooda codsi.
