Gariiradda Galvalume / Aluzinc gariiradda / Zincalum gariiradda waa Zn-Al alloy dahaarka, iyo ka kooban daahan waa 55% Al, 43.3% Zn, iyo 1.6% Si.Bseides midabka asalka ah, gariiradda aluzinc waxay leedahay midab buluug, cagaar, dahab iyo casaan.Iska caabbinta daxalka ee aadka u wanaagsan, birta noocaan ah ayaa si tartiib tartiib ah u bedelaysa birta galvanized oo si weyn looga isticmaalo adduunka oo dhan.
Dusha sare waa siman oo waxay leedahay iska caabbinta daxalka atmospheric aad u fiican.Iska caabbinta daxalka atmospheric waa 2-6 jeer ka sarreeya xaashida galvanized kulul ee dhumucdiisuna waxay la mid tahay.Isla mar ahaantaana, waxay leedahay iska caabin heerkul sarreeya oo la mid ah xaashida aluminium-kulul-kulul, aluminium-zinc alloy dahaarka birta ah Waxaa loo isticmaali karaa waqti dheer heerkul sare sida 315 ℃, iyo dheer isticmaalka muddada heerkulka 500 ℃～600 ℃;Waxay leedahay iska caabin wanaagsan oo biyaha ah iyo iska caabin daxalka ciidda, iyo iska caabbinta daxalka biyaha ayaa ka fiican xaashida galvanized-ka-kulul iyo xaashida aluminium-kulul-kulul.Daxalka carradu wuu ka fiican yahay xaashida galvanized-kulushahay;Waxay leedahay rinjiyeyn heer sare ah iyo waxqabadka habaynta wanaagsan, iyo habaynteeda iyo alxanka waxay la mid yihiin xaashida kulul ee galvanized, waxaa lagu farsamayn karaa laabasho qabow, shaabad, iwm, waxayna leedahay muuqaal wanaagsan.
Aluminium-zinc dahaarka birta dahaarka leh waxay leedahay labadaba sifooyinka xaashida birta galvanized kulul iyo xaashida birta aluminium-ku-kulul.Sidaa darteed, meesha xaashida birta ah ee kuleylka leh ee la isticmaalo, aluminium-zinc alloy sheet birta dahaarka leh ayaa la isticmaali karaa, sidoo kale waxay qayb ahaan bedeli kartaa xaashida birta aluminium-kuleylka ah.Waxay leedahay codsiyo kala duwan oo kala duwan, sida saqafka saqafka, darbiyada gidaarka, birta khafiifka ah, hiitarka kuleyliyaha, meydadka baabuurta, haamaha shidaalka, cajaladaha birta gaashaaman ee fiilada, koriyooyinka balaastiigga ah, weelasha maraakiibta, qalabka guriga iyo qalabka, Foornooyinka, qaraxa -suunka birta ah ee aan caddayn, daboolka sare ee qaboojiyaha iyo nidaamyada hawo-qaadista, kuleyliyaha biyaha qorraxda, sanduuqyada baakadaha ee alaabta kiimikada, iyo saxannada midabka midabka, tuubooyinka alxanka, daaqadaha birta, qalabka birta qabow-sameeyay ee warshadaha birta, iwm., waxay leeyihiin a rajo codsi aad u ballaaran.
Qiimaha aluminium-zinc dahaarka birta dahaarka ah ayaa ka sarreeya tan caadiga ah ee xaashida birta galvanized kulul, laakiin sababtoo ah cufnaanta gaarka ah ee aluminiumku wuu ka yar yahay zinc, culeyska gaarka ah ee aluminium-zinc alloy daahan waa 3.75kg/dm3 , halka culeyska gaarka ah ee zinc uu yahay 7.1kg / dm3, sidaas darteed miisaanka daahan Dhumucda aluminium-zinc alloy daahan ee 150g / m2 (laba dhinac) waxay la mid tahay tan saxan birta galvanized kulul. daahan culeyskiisu yahay 275g/m2 (laba dhinac), kaas oo si weyn u badbaadiya biraha daahan ee qaaliga ah.
Iska caabbinta daxalka sare: caabbinta daxalka ee alaabadu waa 6-8 jeer ka mid ah xaashida galvanized guud, mana daxalaysan doonto 20 sano deegaanno kala duwan;
Iska caabbinta oksaydhka heerkulka sare: isticmaalka joogtada ah ama joogtada ah ee jawi heerkul sare ah oo ah 315 darajo Celsius ma keenayso wax midab ama qallafsan;Isticmaalka joogtada ah ama joogtada ah ee jawi heerkul sare ah oo ah 490 darajo Celsius ma si xun u oxidize ama ma soo saari doonto miisaanka birta;
Milicsiga kulaylka sare: Milicsiga kulaylka alaabtu waa ka sarreeyaa 75%, taas oo laba jeer ka badan xaashida galvanized;
Habaynta fudud: waxay la kulmi kartaa farsamaynta shaambo, xiirid, foorarsi, iwm.;
Muuqaalka quruxda badan: qaabka qalinka cad ee barafka cad, qurux badan oo qurux badan, si toos ah ayaa loo isticmaali karaa iyada oo aan rinjiyeyn;
Ku buufinta dusha sare: Waa substrate wanaagsan oo dahaarka rinjiga ah.Dahaarka isku dhafan ee walxaha iyo walxaha organic waxay ku siin karaan ilaalin waxtar leh oo ka hortagaya daxalka hoos yimaada dahaarka organic.
