Galvanized xaashi bir ah

Galvanized sheet waa bir oo korkeeda lagu dahaadhay lakabka zinc.Galvanizing waa hab wax ku ool ah oo wax ku ool ah oo ka hortag ah miridhku kaas oo adduunka lagu isticmaalo qiyaastii kala badh wax soo saarka zinc ee adduunka.
Codsiga:
Saxanka birta ah ee galvanized waa in laga ilaaliyo dusha sare ee saxanka birta in uu daxaleeyo si uu u kordhiyo cimrigiisa adeega, oo lagu dahaadhay lakabka zinc birta ah ee dusha sare ee saxanka birta, saxan bir ah oo dahaarka leh oo loo yaqaan galvanized plate.
Kala soocidda

Marka loo eego hababka wax-soo-saarka iyo hab-socodka waxaa loo qaybin karaa qaybaha soo socda:
dhuuban kulul xaashi bir galvanized.Waraaqda birta ah waxaa lagu dhex shubaa qubeyska zinc la dhalaaliyay si loogu dhejiyo birta zinc-plated ee dusha sare.Waqtigan xaadirka ah, waxaa inta badan soo saara geeddi-socod isdaba-joog ah, taas oo ah, saxan bir duuban ayaa si joogto ah loogu dhex rusheeyaa taangiga dhejiska kaas oo zinc lagu dhalaaliyo si loo sameeyo xaashi bir ah oo galvanized ah;
xaashi galvanized alloyed.Xaashidan birta ah waxaa sidoo kale lagu soo saaraa qulqulo kulul, laakiin isla markiiba ka dib marka la sii daayo, waxaa lagu kululeeyaa ilaa 500 ° C si loo sameeyo filim daawaha ah oo zinc iyo bir ah.Xaashidan galvanized waxay leedahay adhesion wanaagsan iyo weldability ee daahan;
saxan bir ah oo electro-galvanized.Wax soo saarka ee xaashida galvanized sida by electroplating ayaa processing wanaagsan.Si kastaba ha ahaatee, dahaarka ayaa khafiif ah oo iska caabbinta daxalka uma fiicna sida tan xaashida kulul ee galvanized;
dahaadh hal dhinac ah iyo bir galvanized kala duwan oo laba-dhinac ah.Bir galvanized-ka ah oo hal dhinac ah, taas oo ah, badeecad hal dhinac kaliya lagu galvanized.Waxay leedahay la qabsi ka wanaagsan xaashida galvanized laba-geesoodka ah ee alxanka, rinjiyeynta, daaweynta ka hortagga miridhku iyo habaynta.
Si looga gudbo cilladaha zinc aan la daboolin ee hal dhinac ah, waxaa jira xaashi galvanized ah oo lagu daboolay lakab khafiif ah oo zinc ah oo dhinaca kale ah, taas oo ah, xaashi galvanized kala duwan oo laba geesood ah;
daawaha, xaashi galvanized ah oo isku dhafan.Waxay ka samaysan tahay zinc iyo biraha kale sida aluminium, lead, zinc, iwm, ama xitaa bir isku dhejisan.saxan bir Tani waxay leedahay iska caabin miridhku aad u fiican iyo sifooyinka daahan wanaagsan;
Marka laga soo tago shanta nooc ee kore, waxa kale oo jira xaashiyo bir ah oo midabaysan, xaashiyo galvanized ah oo daabacan, iyo go'yaal galvanized ah oo polyvinyl chloride ah.Si kastaba ha ahaatee, kuwa ugu badan ee la isticmaalo ayaa weli ah xaashiyo galvanized kulul oo kulul.
Heerarka badeecada khuseeya waxay qeexayaan dhumucda caadiga ah, dhererka iyo ballaca lagu taliyay xaashida galvanized iyo dulqaadkooda.Guud ahaan, sii dhumucdiisuna xaashi galvanized waa, ka weyn ee dulqaadku waa, halkii go'an 0.02-0.04 mm, dhumucdiisuna waxay sidoo kale waxay leedahay shuruudo kala duwan sida ay dhalidda, coefficient u adkaysta, iwm 5 mm, dhumucda xaashida.Guud ahaan inta u dhaxaysa 0.4-3.2.
Dusha sare
(1) Xaaladda dusha sare: xaashida galvanized waxay leedahay xaalado daaweyn oo kala duwan sababtoo ah hababka daaweynta ee kala duwan ee habka daahan, sida ubaxa zinc caadiga ah, ubaxa zinc wanaagsan, ubaxa zinc flat, ubax aan zinc lahayn iyo dusha fosfatka.Heerarka Jarmalku sidoo kale waxay qeexayaan heerarka dusha sare.
(2) Xaashiyaha galvanized waa inuu lahaadaa muuqaal wanaagsan oo waa inuusan lahayn cillado waxyeello leh sida dahaadh la'aan, dalool, dildilaacyo iyo wasakh, dhumucdiisuna badan tahay, xoqin, wasakh acid chromic, miridh cad, iwm. Heerarka shisheeye aad uma cadda. ku saabsan cilladaha muuqaalka gaarka ah.Cilladaha gaarka ah qaarkood waa in lagu qoraa heshiiska marka la dalbanayo.
