Taarikada harqood ee kulul ee loo isticmaalo xadhkaha gudbinta korantada, hirgalinta jaangoynta ee habka galvanization-ka kulul ayaa si toos ah u go'aamisa nolosha adeegga iyo waxqabadka badbaadada alaabta. Maqaalkani waxa uu bixin doonaa horudhac tafatiran oo ka imanaya dhinacyada mabaadi'da habka, habraacyada asaasiga ah, qodobbada xakamaynta tayada muhiimka ah, faa'iidooyinka habka, iyo heerarka u hoggaansanaanta ganacsiga shisheeye.
Kulul{0}Galvanizing-ku waa asal ahaan falcelin isku xidhid bir ah. Marka dusha - harqoodka birta ee la nadiifiyey lagu geliyo zinc dhalaalaysa qiyaastii 450 darajo, birta (Fe) ee ku jirta substrate-ka birta iyo zinc (Zn) ee zinc dhalaalaysa waxay maraan fidin joogto ah iyo falcelinta alloying, samaynta lakab saddex-lakab galvanized ah. Gudaha gudaha, lakabyadani waa:
Birta -Lakabka Aloyiga Zinc (Lakabka Gudaha): Si toos ah ugu xidhan substrate-ka birta, inta badan ka kooban Fe3Zn10 iyo FeZn7, waa cufan oo waxa uu leeyahay xabag aad u xoog badan, oo bixisa dammaanadda udub dhexaadka u ah iska caabbinta daxalka iyo ka hortagga- sifooyinka diirinta lakabka galvanized.
Zinc-Lakabka Alloy birta (Lakabka Dhexe): Ka kooban FeZn13, waxa uu leeyahay dhumuc dhexdhexaad ah oo isku daraa adaygga iyo adkaanta.
Lakabka Zinc ee saafiga ah (Lakabka Dibadda): Dabool lakabka ugu dambeeya, waa jilicsan yahay oo ductile, samaynta filimka difaaca ee zinc oxide cufan ee dusha sare. Intaa waxaa dheer, haddii ay dhacdo xagashada gudaha, waxay siisaa ilaalin joogto ah aagga la xoqay iyada oo loo marayo saameynta ilaalinta anodic-ka ee allabariga.
Kuleylka Hot Dip Galvanized Yake Plates, wadarta dhumucda sadexda{0}qaabka lakabka waa in si adag loo xakameeyaa si ay uga sarreyso 65μm. Codsiyada sare - shuruudaha, dhumucda waa la kordhin karaa ilaa 85μm si loo daboolo baahiyaha buufinta milixdu sareeyso iyo bay'ada aadka u wasakhaysan.
Habka soo saarista Hot Dip Galvanized Yoke Plates waa in ay raacdaa habka caadiga ah ee daawaynta - kulul -kuleelka galvanizing - daawaynta kadib - kormeerka. Waxaa ka mid ah, pretreatment waa tallaabada muhiimka ah ee go'aamisa tayada galvanizing oo si toos ah u saameeya isku-xidhka iyo isku-duubnaanta daboolka.
Daawaynta hoos u dhigista: Isticmaal wax-ka-hortagga alkaline si aad ugu qoyso 60{2}80 darajo 5{3}}10 daqiiqo, ama isticmaal nadiifinta buufinta sare{5} si aad uga saarto saliidda stamping, saliida ka hortagga miridhku, boodhka iyo wasakhda saliidda ee dusha saxanka isku xidha. Cidhifyada shaambadaysan ee saxanadda harqoodka iyo gidaarada gudaha ee godadka boodhka waa meelaha u nugul hadhaaga saliidda, una baahan waqti dheerad ah oo lagu buufinayo ama nadiifinta ultrasonic-ka caawisay.
Biyo-dhaqidda iyo sifaynta: Ku raaci haanta biyaha ee aasaasiga ah iyo kan sare si aad meesha uga saarto hadhaaga wasakhaynta. Habkani waa in uu xaqiijiyaa in aanay biyo ururin ama hadhaaga hadhaagu ku jirin godadka boodhka.
Asiidh-qaadista iyo saarista miridhku: U isticmaal aashitada hydrochloric si aad wax u qaado, u gelisid heerkulka qolka 10{2}}15 daqiiqo si aad uga saarto miisaanka oksaydhka, miridhka, iyo lakabka duuban ee oksaydhka dusha saxanka harqoodka. Miisaanka oksaydhka dhumucdiisuna waxay tahay, wakhtiga qajaarka si ku haboon ayaa loo kordhin karaa, laakiin koontarool adag ayaa loo baahan yahay si looga fogaado qaadashada xad dhaafka ah, taas oo keeni karta qallafsanaanta dusha sare iyo hoos u dhigista dahaarka.
Biyo-dhaqidda iyo dhex-dhexaadnimada: Ku dhex geli haanta dhexdhexaadinta alkaline si aad u dhex-geliso walxaha haraaga ah ee acidic ah, hubinta meel dhexdhexaad ah. Darbiyada gudaha ee godadka botka waa in si fiican loo biyo raaciyo si looga hortago hadhaaga aashitada inay sababto finan ku dhaca lakabka galvanized.
Drying and preheating: Dry at 120-150℃ for 10-15 minutes to completely remove surface moisture. The surface must be free of water stains and oxidation; otherwise, the galvanized layer may show signs of blistering or exposure to oxidized material. Defects such as those mentioned above; Zinc immersion: The zinc immersion temperature is strictly controlled at 445-460℃. The immersion time is adjusted according to the thickness of the plate. When the thickness is ≤6mm, the immersion time is 1-2 minutes. When the thickness is >6mm, wakhtiga immersion waa 2-3 daqiiqo. Daaweynta qaboojinta: Isticmaal qaboojinta hawada ama qaboojinta ceeryaamo biyaha si aad ugu qaboojiso heerkulka qolka. Inta lagu jiro habka qaboojinta, ka fogow isku dhacyada u dhexeeya saxarada kulul ee Galvanized Hot si aad uga hortagto xagashada dahaarka.
Taarikada harqoodka Galvanized Hot Dip ee la dhoofiyo, habka wax soo saarku waa inuu buuxiyaa heerarka la xiriira iyo shuruudaha shahaadaynta ee suuqa la beegsanayo; haddii kale suuqa ma geli karaan. Sida soo-saare xirfadle ah, shirkadeena waxay mudnaanta siisaa tayada alaabta; fadlan xor u noqo inaad iibsato
