Kodi hot dip galvanizing ndi chiyani?

Hot-dip galvanizing ndi njira wamba yophimba chitsulo pamwamba ndi wosanjikiza wa zinc, cholinga chake chachikulu ndikuteteza zitsulo okosijeni ndi dzimbiri.

Hot-kuviika galvanizing ndi kumiza zitsulo workpiece mu sungunuka zinki madzi kupanga zoteteza wosanjikiza. Njira yeniyeni ndi iyi:

Kuchiza:
Kuchepetsa mafuta: Chotsani zonyansa monga mafuta, fumbi, ndi zina zambiri pamwamba pazitsulo, nthawi zambiri mumagwiritsa ntchito njira ya alkaline poyeretsa.
Kutola: Gwiritsani ntchito dilute hydrochloric acid kapena sulfuric acid kuti muchotse sikelo ya oxide ndi dzimbiri pazitsulo kuti pakhale malo oyera.
Kusamba madzi: Chotsani zinthu za acidic zomwe zatsala panthawi ya pickling kuti musakhudze njira zotsatila.
Chithandizo cha plating: Miwiritsani chogwirira ntchito mu plating aid (monga zinc chloride solution) kuti mupange filimu yowonda yoteteza kuti chitsulo chisatulukenso ndi oxidizing isanayambe kusonkhezera ndikuwongolera kumamatira kwa zinki.

Kutentha-kuviika galvanizing:
Miwiritsani chogwirirapo kale muzitsulo zosungunula za zinki pafupifupi 450 ° C kuti mugwirizane ndi zinki ndi matrix achitsulo kuti mupange wosanjikiza wachitsulo ndi zinki wosanjikiza.

Kuziziritsa:
Chotsani chogwiritsira ntchito mumadzimadzi a zinki, ndikuziziritsa ndi mpweya kapena madzi kuti zinki zikhazikike mofulumira ndikupanga yunifolomu yotetezera.

Pambuyo pa chithandizo:
Nthawi zina passivation mankhwala chofunika kuteteza woyera dzimbiri padziko kanasonkhezereka wosanjikiza.
Malizitsani pamwamba pa workpiece, monga kuchotsa owonjezera zinki tinatake tozungulira, burrs, etc.

Kuyang'ana kwabwino:
Chongani makulidwe, adhesion, maonekedwe, etc. wa kanasonkhezereka wosanjikiza kuonetsetsa kuti galvanizing khalidwe workpiece akukumana muyezo.

Makhalidwe a kutentha-kuviika galvanizing: nthaka wosanjikiza ndi wandiweyani ndipo alikukana dzimbiri mwamphamvu, yomwe ili yoyenerakugwiritsa ntchito kunja kwa nthawi yayitali, koma pamwamba pake ndi yopyapyala ndipo mawonekedwe ake amakhala oyipa pang'ono.

Zogulitsa zomwe zimagwiritsidwa ntchito ndi galvanizing yotentha zimagwiritsidwa ntchito kwambiri pazinthu monga zomangamanga, zoyendera, magetsi, mafakitale amphamvu, makina ndi zipangizo zolemera, chithandizo cha madzi ndi malo osungira zachilengedwe, kupanga magalimoto, ulimi ndi famu, etc. Mwachitsanzo, muzitsulo za elevator:njanji za elevator, mabulaketi a njanji, mabulaketi a chingwe ndi mabulaketi,Guide njanji cholumikizira mbale, zitsulo zopangira shaft, ma guardrails ndi zida zotetezera, utsi ndi mabulaketi a zida zowunikira, zomangira (mabawuti, mtedza) amafunikiranso kuthirira kotentha.
