Maxaad u baahan tahay si aad u diyaariso silig birta galvanized kulul ka hor inta aan galvanized?

1. Xakamaynta habka korantada
Xaaladda adeegga iyo nolosha adeegga eesilig bir galvanizedama qaybaha waxay si dhow ula xiriiraan dhumucda dahaarka.Marka ay sii adkaato shuruudaha isticmaalka iyo muddada dheer ee nolosha adeegga, waa in ay sii weynaataa lakabka loo baahan yahay ee silig birta galvanized ah.Alaabooyinka kala duwan, marka loo eego jawiga gaarka ah (heerkulka, qoyaanka, roobka, halabuurka atmospheric, iwm.) si loo go'aamiyo nolosha adeegga la filayo ee dhumucda daahan, dhumucdiisuna waxay keeni doontaa dhammaan noocyada qashinka.Laakiin haddii dhumucdiisu aanay ku filnayn, ma gaadhi doonto shuruudaha nolosha adeegga ee la filayo.Soo saarayaasha kala duwan, marka loo eego shuruudaha qalabka iyaga u gaar ah, marka la eego go'aaminta dahaadhka, diyaarinta ugu horreysa ee socodka geedi socodka dhammaystiran oo macquul ah, cabbirrada cad ee dahaadhka, xakamaynta xallinta dhejinta, hawlgalka caadiga ah.

2, dahaadhay silig kulul dahaadhay ka dib markii processing
Daaweynta dahaadhka ka dib (passivation, dhalaal kulul, shaabadeynta iyo saarista hydrogen, iwm.) Ujeedada kor u qaadista guryaha ilaalinta, qurxinta iyo ujeedooyinka kale ee gaarka ah.Ka dib markii galvanized, passivation chromate ama daaweynta beddelka kale ayaa guud ahaan looga baahan yahay si ay u sameeyaan nooca u dhiganta filimka beddelka, taas oo ah mid ka mid ah hababka muhiimka ah si loo hubiyo tayada post-plating.
3, habka galvanized silig galvanized
Qaybaha muhiimka ah iyo kuwa muhiimka ah ee leh xoogga xajinta ee ka weyn 1034Mpa, walbahaarka waa in laga saaraa 200 ± 10 ℃ in ka badan 1 saac ka hor inta aan la dhejin, iyo qaybaha carburized ama dusha adag, cadaadiska waa in laga saaraa 140 ± 10 ℃ wax ka badan in ka badan 5 saacadood.Walaxda nadiifinta ee loo isticmaalo nadiifinta wax saameyn ah kuma yeelan doonto xoogga ku-xidhka dahaarka iyo wax daxalka ah ee substrate-ka.Firfircoonida aysiidhka Xalka asiidhka firfircoonida waa inuu awood u yeeshaa inuu ka saaro alaabada daxalka ah iyo filimka oksaydhka (maqaarka) ee dusha qaybaha iyada oo aan daxal xad-dhaaf ah lahayn shaxanka.
Galvanizing waxaa lagu samayn karaa galvanizing zincate ama galvanizing chloride.Wax-ku-dar ku habboon waa in loo adeegsadaa si loo helo dahaar buuxiya shuruudaha heerkan.Daaweynta iftiinka waa in la sameeyaa ka dib marka la dhajiyo iftiinka.Qaybaha u baahan in la fuuq-baxo si ay u maraan waa in ay noqdaan kuwo la dhaqo ka dib fuuq-baxa.Ka hor inta aan dhicin, 1% H2SO4 ama 1% hydrochloric acid waa in lagu codsadaa firfircoonida 5 ~ 15s.Gudbinta waa in lagu daaweeyaa chromate midab leh ilaa si kale loogu qeexin sawirada naqshadeynta.
Codsiga ballaaran ee siliga galvanized wuxuu u keenay wax soo saarka dadka iyo nolosha, laakiin habka wax soo saarka ee siliga birta sidoo kale maaha in la dhayalsado.In wax soo saarka warshadaha, habka wax soo saarka ee silig galvanized waa in si adag loo xakameeyo si loo hubiyo tayada silig galvanized.
