Maxaan u baahanahay si aan ugu diyaarino silig birta galvanized kulul ka hor inta aan galvanized?

1. Xakamaynta habka korantada
Xaaladda adeegga iyo nolosha adeegga ee siligga birta galvanized ama qayb ka mid ah waxay si dhow ula xiriiraan dhumucda dahaarka korantada.Marka ay sii adkaadaan shuruudaha isticmaalka iyo cimriga adeegga, waa sii dhumuc weynaanta lakabka fiilada galvanized ee loo baahan yahay.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
Dib-u-dhigid (passivation, dhalaal kulul, xirid iyo fuuq-bax, iwm.) Ujeedada kor u qaadista guryaha ilaalinta, qurxinta iyo ujeedooyin kale oo gaar 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 waa in laga nafisiyaa walbahaarka 200 ± 10 ℃ in ka badan 1 saac ka hor inta aan la dhajin, iyo qaybaha carburized ama dusha adag ee dusha sare waa in laga saaro cadaadiska at 140 ± 10 ℃ 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.Daawaynta luminescence waa in la sameeyaa ka dib marka la dhejiyo luminescence.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 dabaqaa si loo dhaqaajiyo 5 ~ 15s.Gudbinta waa in lagu daaweeyaa chromate midab leh ilaa si kale loogu qeexin sawirada naqshadeynta.
Codsiga ballaaran ee siligga galvanized ayaa u keenay wax soo saarka dadka iyo nolosha, laakiin habka wax soo saarka fiilada birta maaha mid la dhayalsan karo.In wax soo saarka warshadaha, habka wax soo saarka ee silig galvanized waa in si adag loo xakameeyo si loo hubiyo tayada silig galvanized.
