Farqiga u dhexeeya gariiradda galvanized iyo galvalumed gariiradda
Lakabka walxaha zinc ayaa si siman loo qaybiyaa dusha sare ee xaashida galvanized, kaas oo u dhaqma sida ilaalinta anodic ee birta saldhigga ah, taas oo ah in la yiraahdo, daxalka beddelka ah ee walxaha zinc ayaa ilaaliya isticmaalka birta saldhigga ah.Halkan, zinc waa sida mid muhiim ah Gaashaanlaha hilibka ee ku wareegsan jilayaasha waa in la huraa ka hor intaanay jilayaasha dhexe soo jeedin.

Dahaarka dusha sare ee xaashida galvanized wuxuu ka kooban yahay 55% aluminium, 43.5% zinc iyo qadar yar oo walxo kale ah.Marka la eego heerka microscopic, dahaarka galvanized wuxuu soo bandhigayaa qaab-dhismeedka malabka, iyo "malab" ka kooban aluminium ka kooban Zinc, kiiskan, inkastoo daahan aluminium-zinc ayaa sidoo kale ka ciyaara doorka ilaalinta anodic, dhinaca kale, sababtoo ah hoos u dhigista maadada zinc, dhinaca kale, sababtoo ah maaddada zinc waxaa lagu duuduubay aluminium, ma fududa in lagu dhejiyo korantada, sidaas darteed doorka ilaalinta anodic aad ayuu u yareeyaa.Halkan, zinc galvanized wuxuu la mid yahay hubka jirka ee hawlgallada muhiimka ah.Marka dhibic la jabiyo, ilaalinta meeshaas waa la waayay.Sidaa darteed, marka xaashida galvanized la gooyo, ilaalinta cidhifka la jaray ayaa asal ahaan lumay, sidaas darteed si dhakhso ah ayey u miridhsan doontaa.Sidaa darteed, xaashida galvanized waa in la gooyaa sida ugu yar ee suurtogalka ah.Marka la gooyo, mari rinjiga ka-hortagga miridhku ama rinjiga Zinc-ka leh ayaa ilaaliya geesaha, si nolosha adeegga guddiga loo kordhiyo.

1. Alaabta daahan zinc ee caadiga ah (GI) Alaabooyinka galvanized ee caadiga ah ee kulul-muquufinta waxaa loo qaybin karaa spangle caadiga ah, spangle yar, malaha spangle iyo alaabta dusha siman sida waafaqsan xaalada dusha sare.Sababtoo ah caabbinta daxalka wanaagsan, farsamaynta aadka u fiican iyo samaynta waxqabadka, kharashka wax soo saarka hooseeya, iyo muuqaalka quruxda badan, waxaa si ballaaran loo isticmaalaa dhismaha, baabuurta, qalabka guriga iyo warshadaha kale.Gaar ahaan spangle yar yar oo aan lahayn alaabada dahaarka ah, miraha dusha sare waa kuwo fiican, cufan, siman, oo leh dahaar ka fiican iyo iska caabin daxalka, gaar ahaan qalabka guriga, midabka midabka iyo warshadaha kale.
2. Zinc Aluminium Alloy Coated Sheet (GF)
Waraaqda dahaarka leh ee Zinc-aluminium waxaa sidoo kale loo yaqaannaa xaashida birta galvanized-aluminium-yar, daahankuna wuxuu ka kooban yahay
5% Al, 95% Zn, iyo raadadka curiyayaasha dhulka naadirka ah.Faa'iidooyinka ugu muhiimsan ayaa ah in caagagga iyo dhejinta daboolka ay aad u fiican yihiin, iyo iska caabbinta daxalka ka hor iyo ka dib isbeddelka aan isbeddelin;caabbinta daxalka atmospheric waa 2 ilaa 3 jeer ka mid ah xaashida galvanized kulul-muquufin caadiga ah, oo waxay leedahay jaakad wanaagsan iyo weldability.Dhammaan xaashida galvanized, waxay leedahay adayga ugu fiican, iska caabinta daxalka iyo qaabaynta u dhiganta xaashida galvanized.Alaabtan waxaa inta badan loo isticmaalaa daxalka u adkaysta iyo bay'adaha u adkaysta cimilada iyo waxyaalaha dahaadhka ah.
3.Aluminium-zinc alloy saxan (GL) Qaab dhismeedka dahaarka ee saxanka aluminium-zinc ee dahaarka ah waa Al-Zn alloy, iyo halabuurka dahaarka waa 55% Al, 43.3% Zn, 1.6% Si.Oogada sare waa siman oo waxay leedahay caabbinta daxalka atmospheric aad u fiican, kaas oo 2-6 jeer ka sarreeya isla xaashida galvanized-kulusha leh.Waxay leedahay iska caabin heerkul sarreeya oo la mid ah saxan aluminium kuleyl ah, waxaana la isticmaali karaa waqti dheer iyada oo aan wax midab ah ama qallafsanaan heerkul sare oo 315 darajo ah.Iska caabbinta daxalka biyaha ayaa ka fiican kan xaashida kulul ee galvanized-ka ah iyo xaashida aluminiumka ah ee kuleylka leh, iyo iska caabbinta daxalka ciidda ayaa ka fiican kan xaashida kulul ee galvanized.Milicsigeeda kulaylka ayaa ka sarreeya 75%, taas oo laba jeer ka badan xaashida galvanized ee caadiga ah.Waxay leedahay rinjiyeyn wanaagsan iyo farsamayn, waxayna si tartiib tartiib ah u beddeshaa xaashida galvanized oo si weyn looga isticmaalo adduunka.
4. xaashida galvanized-ka kulul--kulul-kulul waa xaashi galvanized ah oo si toos ah loo soo saaray iyadoo la qaadayo laguna galvanized xaashi kulul-duuban sida substrate-ka.Looxa ayaa si weyn loogu isticmaali karaa dhismaha, baabuurta, silooska birta ah, baabuurta rakaabka ee tareenada, looxyada ilaalada waddooyinka, iwm. Waqtigan xaadirka ah, wax soo saarka gudaha ee xaashida galvanized ee kulul ayaa ah mid aad u yar, iyo inta badan khadadka wax-soo-saarka galvanized ee hore u jiray. la dhammeeyey oo la geliyey wax-soo-saarku waa xaashi galvanized ah oo leh xaashi qabow-duuban sida substrate-ka.Marka la barbar dhigo xaashida galvanized-rogid-qabow, farqiga u dhexeeya waxqabadka u dhexeeya xaashida galvanized-ka kulul iyo xaashida galvanized-duuban ma aha mid aad u weyn.Sababtoo ah xaashida galvanized kulul ee duuban waxay badbaadisaa habka qaboojinta qabowga, qiimaha wax soo saarku wuu hooseeyaa, wuxuuna leeyahay faa'iido qiimo leh oo muuqda.
