Galvanized Steel Pipe Rust iyo shuruudaha farsamada

Galvanized Steel Pipe miridhku

Dhuumaha birta galvanized miridhku waxa uu inta badan u yahay Zinc ku milmay aashitada waxa kale oo lagu milmaa alkali, markaa u yeedh birta jinsiga.Zinc ee hawada qalalan waa ku dhawaad ​​wax isbedel ah ma jiraan.Hawada qoyan, dusha zinc wuxuu dhalin doonaa filim cufan oo ah zinc carbonate aasaasiga ah.Ka kooban sulfur dioxide, hydrogen sulfide iyo jawiga badda, caabbinta liidata ee zinc, gaar ahaan jawiga kulul iyo qoyan ee ay ku jiraan acids organic, daahan zinc wuxuu si fudud u noqon karaa daxal.Zinc heerka electrode iman kara ee-0.76V, substrate birta ah, daahan zinc waa daahan anodic, kaas oo loo isticmaalo si looga hortago daxalka ee birta iyo birta, faa'iidooyinka iyo khasaaraha sifooyinka ilaalinta ee xiriirka dhumucdiisuna waa weyn.

Daahan Zinc, passivation, midabaynta ama dahaarka ilaalinta iftiinka, waxay si weyn u wanaajin kartaa ilaalinta iyo qurxinta.Zinc oxide ee hawada, dusha sare ee samaynta miridhku cad, xaaladdani waa mid caadi ah.Waxay kuxirantahay xariijintaada waa galvanized dip kulul ama electro-galvanized, maquufin kulul galvanized, ka dibna sababtoo ah lakabka xad qaro weyn ee zinc si ay u abuuraan miridhku cad ma saamayn damaanad caadiga ah, sababtoo ah heerka oksaydhka ee zinc ee hawadu aad u gaabis ah.Electro-galvanized ma fududa in la yiraahdo.Ha arkin miridhku ma saameyn doono.Markaad rabto inaad badbaadiso birta galvanized si aad uga taxaddarto inaadan qoyan iyo hawo cimilada kulul waa mid aad u fudud in la caareeyo, qaar ka mid ah jiilaalka, ka dibna u hoggaansamo dheer.

Shuruudaha farsamada ee Dhuumaha Galvanized Steel

Nidaamka hubinta tayada tuubada birta galvanized kulul, qodobka ugu muhiimsan waa waxqabadka codsiga ee tuubada galvanized.
Barta foorarsiga ee galvanized-ka kulul waxaa loola jeedaa ifafaale ah walxo bir ah oo leh dhalid, heerka foorarsiga muunada ee birta galvanized asal ahaan aad u muhiim ah, sababtoo ah waxay tijaabin kartaa tuubada birta galvanized cadaadiska dibadda marka falcelinta , Haddii tijaabada galvanized birta cadaadiska dhibic muhiim ah, waxaan noqon karnaa xoojinta ku habboon tuubooyinka birta galvanized in la awoodi karo sida waafaqsan shuruudaha macaamiisha.
Haddii korontadu dhacdo, waa in la kala saaro dhibcaha dhalidda sare iyo hoose.Dhibicda wax-soo-saarka sare waa muunadda lagu soo saaro awoodda hoos u dhacday markii ugu horreysay ka hor inta aysan dhicin cadaadiska ugu badan;dhibicda wax-soo-saarka hoose waa cadaadiska ugu yar marka laga reebo saameynta bilowga ah ee ku-meel-gaarka ah, marxaladda wax-soo-saarka.Tusmada walxaha adag ee birta si ay iskaga caabiyaan walxaha adag ee dhexgalka awoodda dusha sare, oo loo yaqaan qallafsanaanta.
Iyada oo ku xidhan hababka tijaabada iyo baaxadda engegnaanta waxaa loo qaybin karaa qallafsanaanta Brinell, Rockwell engegnaanta, Vickers adkaanta, adkaanta xeebta, qallafsanaanta yar iyo heerkulka sare.Caadi ahaan loo isticmaalo tubada Brinell, Rockwell, Vickers adag.
