Chitoliro Chachitsulo cha Galvanized
Kampani yathu imakhazikika pakutumiza kunja kwazitsulo zopanda msokochitoliro cha malata, Chitoliro Chopanda Msokonezo, SMLS kanasonkhezereka chitoliro, WEDED kanasonkhezereka chitoliro.
Kodi pali kusiyana kotani pakati pa malata otentha ndi malata ozizira?
Kutentha-kuviika galvanizing ndi ozizira kanasonkhezereka kusiyana:
1. Galvanizing, amatchedwanso otentha kuviika kanasonkhezereka, iye ndi ingot anasungunuka pa kutentha, chiwerengero cha zinthu zowonjezera m'malo, ndiye choviikidwa kanasonkhezereka zitsulo kapangidwe kagawo, chigawo chachitsulo pa wosanjikiza nthaka ❖ kuyanika . Ubwino wa kutentha-kuviika galvanizing dzimbiri luso lake, adhesion ndi kuuma kwa nthaka ❖ kuyanika ndi bwino.
"Cold yokutidwa" kapena "plating", mwachitsanzo nthaka mchere njira electrolysis, kuti plating pa ❖ kuyanika, kawirikawiri alibe Kutentha, pang'ono nthaka, ndi chonyowa chilengedwe ndi zosavuta kugwa.
2. Dip yotentha yothira malata (galvanizing)
Hot-kuviika galvanizing ndi mankhwala mankhwala, ndi electrochemical anachita.
Cold galvanizing ndi thupi adiresi, basi potsuka pamwamba wosanjikiza nthaka, nthaka wosanjikiza n'zosavuta kugwa. Kumanga ntchito yotentha dip galvanizing.
Njira yopititsira patsogolo yothira yotentha: chitsulo → Kutenthetsa → kuzirala mpaka kutentha malabati → kuzirala →
Cold kanasonkhezereka nthaka ndi 10-50g/m2 yekha, kukana dzimbiri kuposa kuviika otentha kanasonkhezereka kusiyana kwambiri. Amathiridwa ndi mtengo wotsika mtengo.
Hot kuviika kanasonkhezereka zitsulo thupi ndi otentha kuviika kanasonkhezereka pamwamba pansi pa chikhalidwe cha adhesion ake amphamvu, zovuta kugwa, ngakhale pali kuviika otentha.chitoliro cha malatadzimbiri chodabwitsa, koma mu nthawi yaitali kwambiri kukwaniritsa luso, zofunika thanzi.
3. Kusiyana kwaukadaulo
Choyamba, ndi kusiyana kwa ndondomeko: otentha-kuviika galvanizing ndi workpiece degreasing, pickling, kuviika, kuyanika madzi kumiza mu sungunuka nthaka nthawi zina, akhoza anaukitsidwa.
Amatchedwanso electro-galvanized ozizira galvanizing, ndi ntchito electrolysis zipangizo ntchito chidutswa mwa degreasing, pickling zosakaniza positi mu njira nthaka mchere, ndi kulumikiza anode electrolysis zida; m'malo kudutsa mbali zinki mbale chikugwirizana ndi electrolysis zida zabwino, mphamvu pa, ntchito panopa ku cathode kwa anode wa kayendedwe ka kayendedwe ka workpiece adzakhala waikamo mu wosanjikiza nthaka.
Zinc anamaliza kusiyana: palibe ozizira kanasonkhezereka otentha-kuviika galvanizing wosakhwima yowala maonekedwe, koma makulidwe a nthaka ❖ kuyanika ozizira galvanizing mbali otentha-kuviika galvanizing ndi kangapo. Galvanized dzimbiri kukana komanso kangapo.
Mwachidule
Kugwiritsa ntchito
Amagwiritsidwa ntchito makamaka pazigawo zamphamvu ndi zokakamiza, komanso pazolinga zonse za nthunzi, madzi, gasi ndi mapaipi amlengalenga.
