Qalabka villa birta khafiifka ah: inta badan waxaa laga sameeyay xaashi bir khafiif ah iyada oo loo marayo qalabka qabow foorarsiga si loo sameeyo keel bir iftiin ah oo C-qaabeeya, laga bilaabo keel birta iftiinka si loo sameeyo qalfoofka guriga, oo loo yaqaan guri qaab dhismeedka birta fudud ama villa birta fudud .
Xoogga birta waxaa loola jeedaa qallafsanaanta birta, qiimaha sarreeya, xoogga xoogga badan, xoogga ayaa sidoo kale loo tixraacaa sida xoogga wax-soo-saarka, mararka qaarkood ma aha mid ka sarreeya xoogga waa ka fiican yahay, mararka qaarkood tixgeli baahida processing si ay u doortaan heerar kala duwan xoog, sida ka baaraandegidda ficil xajin, birta xoogga sare ayaa dillaaci doonta.
Daahan bir fudud ayaa loo qaybiyaa galvanized iyo aluminium zinc laba nooc:
Galvanizing: intee ka kooban tahay, inta badan eeg qiimaha, fiilooyinka birta fudud guud ahaan waxay isticmaalaan zinc 275 garaam iyo 300 garaam, qiimuhu waa maaddada jiil laba jibaaran oo zinc ah, inta ka kooban maacuunta, waa sii dhumuc weynaanta lakabka zinc.
Galvanizing isbeddellada jireed: Galvanizing waa la soo bandhigay oo waxay la falgashaa ogsijiinta hawada sanadka oo dhan, oogada waxay noqon doontaa madow.
Aluminium iyo zinc plating: AZ150 gaaban, aluminium iyo zinc plating waa galvanized anticorrosion 2-6 jeer, aluminium iyo zinc dahaadhay keel muddada dheer qaawan oo aan lahayn wax isbeddel ah midabka, sida daxalka kiimikada, falcelinta jirka ka dhacdaa dusha sare ee keel. , Samaynta filimka ilaalinta aluminium ee dusha sare ee keel, si walxaha kiimikaad ee dibadda iyo keel u kala soocaan, ilaalinta walxaha jirka ee keel, ka hortagga miridhku.
Zinc G550 aluminis ah oo caadi ahaan loo isticmaalo sifooyin farsamo iyo cabbiro jireed waa sida soo socota:
Magaca dhalidda awoodda laastikada cufnaanta cufnaanta cufnaanta iskudarka ballaadhinta kulaylka
G550 550MPa 2.06X105 N/mm 2 7.85g/cm 3 1.2×10-5℃
Iska caabbinta daxalka ee "aluminium zinc gariiradda" waxay ka timaadaa ilaalinta xannibaadda aluminiumka iyo ilaalinta allabariga ee zinc.Marka zinc loo bixiyo si loo ilaaliyo cidhifyada la gooyey, xagashada, iyo xoqidda dahaarka, aluminiumku wuxuu sameeyaa lakabka oksaydhka ee aan milmi karin kaas oo u shaqeeya sida xannibaad. Gariiradaha birta ah ee aluminiumka ah ee aluminiumka ah ayaa muddo ka badan 20 sano lagu sameeyay tijaabooyin bannaanka ah oo jawiga jawiga kala duwan lagu sameeyay, waxaana la caddeeyay in ilaalinta cirifka goynta ee go'yaasha birta ee aluminiumka ah ay aad uga wanaagsan tahay tan birta galvanized.
Saxanka birta ee aluminiumka ah ee kulul waa nooc ka mid ah saxan bir ah oo qabow-duuban oo leh astaamo kala duwan oo xoog iyo dhumucdiisuna tahay maaddada aasaasiga ah.Waa saxan bir ah oo horay loo dahaadhay oo la helay iyadoo kulul lagu dhejiyay lakabka Al-Zn ee labada dhinac.Boqolkiiba mass ee ka kooban daahan oo ku saabsan 55% Al (aluminium), 43.5% Zn (zinc), 1.5% Si (silicon) .Ururka Al ilaalinta jirka iyo feature ilaalinta electrochemical, adkeysiga sare iyo walxaha zinc leeyahay xoogga birta substrate ah. iyo caag ah, iyo iska caabin daahan ee daahan, waxa ay ilaalin kartaa substrate biraha gudaha mar dambe ka daxalka, marka lagu daro, dusha sare ee sharciyada loading lacag iftiimay la hannaankii ornamental sare, oo uu leeyahay dareen ah gargaarka.
G550+AZ150 hordhac waxqabad:
Iska caabbinta kulaylka:
Cadaadiska kulaylka ee saxanka birta aluminium ee aluminiumku wuxuu ka fiican yahay saxanka birta galvanized, waana u adkaysta oksaydhka heerkulka sare.Zinc aluminium ah ayaa loo isticmaali karaa jawi heerkul sare ah ilaa 315 darajo.
Dib-u-celinta:
Zinc aluminised wuxuu leeyahay milicsi sare, kaas oo ka dhigaya xannibaad kuleyl ah; Milicsiga kulaylka ee zinc aluminiumku wuxuu ku dhawaad laba jeer ka badan yahay zinc galvanized, sidaa darteed waxaa loo isticmaali karaa qaab dhismeedka ugu weyn ee guriga xaaladaha caadiga ah si loo gaaro badbaadinta tamarta.
Tijaabada saxanka birta ee aluminium ee dahaaran:
Tijaabooyinka isbarbardhigga ee taarikada birta dahaarka leh ee meelaha warshadaha ee Pennsylvania, USA:
Aluminium zinc plated saxan bir ah ka dib 30 sano oo ku saabsan raad miridhku ma jirin, dhisme bir ah oo khafiif ah oo qabow oo ka samaysan qaab dhismeedka birta ah ayaa ah qaabka ugu muhiimsan ee derbiga, sidaas darteed qaabka ugu muhiimsan waxaa loo isticmaali karaa in ka badan 100 sano.
Xaqiijinta tayada:
Machinability: si loo buuxiyo shuruudaha duubista, shaabadaynta, foorarsiga iyo qaababka kale ee habaynta.
Iska caabbinta daxalka (marka la barbar dhigo galvanized dip kulul): saxan birta galvanized maquufin kulul leeyahay iska caabin daxalka aad u fiican, nolosha adeegga waa dhumucdiisuna waxay daahan la mid ah saxan bir galvanized caadiga ah 2-6 jeer.
Dib-u-eegis: Awoodda lagu muujinayo kulaylka iyo iftiinka waa 2 jeer tan saxan birta galvanized-kulul-kulul, iyo milicsigu wuu ka weyn yahay 0.70, taas oo ka fiican 0.65 ee ku qeexan EPA Energy Star.Waa qalab dhisme oo tamar-badbaadin ah oo ku habboon.
caabbinta kulaylka: Alaabooyinka galvanizing kulul ee caadiga ah sida caadiga ah waxay isticmaalaan heerkulku kama badna 230℃, 250℃Midab beeli doona, iyo saxan zinc aluminium ah ayaa loo isticmaali karaa 315℃jawiga muddo dheer oo aan midab lahayn.Isbeddelka midabka ee aluminium-zinc ee saxanka birta ah ee lagu daaweeyay kuleylka kulaylka ee Baosteel wuxuu ka yar yahay kan birta aluminium-plated iyo saxanka aluminium-plated ka dib saacadaha 120 ee 300℃.
