Dhuumaha Biraha Galvanized
Dhuumaha galvanized-ka ah waxay u kala qaybsan tahay bir qabow oo dahaadhay tuubo aan fiicneyn iyo tuubo kulul oo kulul.
Tuubooyin diirran oo kulul
Dhuumaha Redu waa in ay sameeyaan falcelinta birta dhalaalaysa iyo birta, lakabka daawaha, si isku darka substrate iyo daahan ee labadaba.Galvanizing-ku-kulul waa birta-qaadista ugu horreysa, si ay meesha uga saarto dusha tuubada birta ee oksaydhka birta, pickling, xal ammonium chloride ama zinc chloride ama ammonium chloride iyo zinc chloride isku dhafan nadiifinta taangiga aqueous, ka dibna u dir kuleylka kulul. haanta quusin.Labbiska dahaarka kulul ee galvanized, ku dheggan xooggan, iyo cimri dheer.
Tubo-daran oo qabow-dahaaran
Galvanized Cold, electro-galvanized, galvanized qadar yar, kaliya 10-50g/m2 iska caabin u gaar ah in daxalka ka badan tuubada galvanized madhxin kulul farqi badan.Soosaarayaasha tuubooyinka galvanized-ka ah ee joogtada ah, si loo hubiyo tayada, badankood ma isticmaalaan elektro-galvanized (qabow-plated).Kaliya kuwa yaryar, qalabka duugoobay iyo ganacsiyada yaryar ee leh koronto galvanized, dabcan, qiimahoodu waa jaban yihiin.Wasaaradda dhismuhu waxay si rasmi ah hoos ugu dhigtay, tuubooyinka galvanized qabow si loo baabi'iyo tignoolajiyada dib u dhaca, mustaqbalka looma ogola inay qaboojiso dhuumaha galvanized biyaha, tuubooyinka gaaska.
Guryaha farsamaysan ee galvanized oo aan kala go 'lahayn
Qalabka farsamada ee birta waa in la hubiyo in tilmaame muhiim ah oo ka mid ah birta isticmaalka dhamaadka isticmaalka (qalabka farsamada), waxay kuxirantahay halabuurka kiimikada iyo daaweynta kulaylka birta.Heerarka birta, marka loo eego shuruudaha kala duwan, bixinta guryaha xajinta (xoogga xajinta, xoogga wax-soo-saarka ama dhererka dhibcaha) iyo adkaanta, adkaanta, shuruudaha isticmaalaha, heerkulka sare iyo hooseeya.

Dhererka tuubooyinka galvanized
- dhexroorka 4 - 16 mm 6000 + 100 mm
- dhexroorka 18 - 42 mm 6000 + 50 mm
Dulqaadyada tuubooyinka dahaarka leh ee zinc
- dulqaadka dhexroorka dibadda:
- dhexroor u dhexeeya 4 - 30 mm±0,08 mm
- dhexroor u dhexeeya 35-38 mm±0,15 mm
- dhexroor ilaa 42 mm±0,20 mm
- U dulqaadashada dhexroorka gudaha waa sida ku cad EN 10305-4
- dulqaadka dhumucda derbiga± 10%
Dhibcaha Birta ee tubooyinka dahaarka leh ee zinc
E235+N iyo E 355+N
Xaaladda dusha sare ee tuubooyinka galvanized
Lakabka koowaad-Zinc elektaroonik ah (Zn)-u dhaqmo sida anode iyo in deegaanka daxaloobay ay marka hore daxal iyo biraha salka waxaa si cathodically looga ilaaliyo daxalka.Dhumucda lakabka zinc wuxuu ahaan karaa inta u dhaxaysa 5 ilaa 30 micrometers (µm).
