Kusiyana pakati pa electro galvanizing ndi otentha galvanizing

1. Malingaliro osiyanasiyana

Hot-dip galvanizing, yomwe imadziwikanso kuti hot-dip galvanizing ndi hot-dip galvanizing, ndi njira yabwino yopangira zitsulo zotsutsana ndi dzimbiri, zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale azitsulo m'mafakitale osiyanasiyana. Ndiko kumiza zitsulo zochotsedwa ndi dzimbiri muzitsulo zosungunula za zinki pafupifupi 500 ° C, kotero kuti pamwamba pa zitsulo zazitsulo zimamatira ku zinki wosanjikiza, kuti akwaniritse cholinga chotsutsa-dzimbiri.

Electrogalvanizing, wotchedwanso ozizira galvanizing mu makampani, ndi ndondomeko ntchito electrolysis kupanga yunifolomu, wandiweyani ndi bwino Bonded zitsulo kapena aloyi mafunsidwe wosanjikiza pamwamba pa workpiece. Poyerekeza ndi zitsulo zina, zinki ndi chitsulo chotsika mtengo komanso chokutidwa mosavuta. Ndizitsulo zotsika mtengo zotsutsana ndi kutu ndipo zimagwiritsidwa ntchito kwambiri kuteteza mbali zachitsulo, makamaka kuti zisawonongeke mumlengalenga, komanso zokongoletsera.

2. Njirayi ndi yosiyana  

Njira yothira galvanizing yamadzi otentha: pickling ya zinthu zomalizidwa - kutsuka - kuwonjezera plating solution - kuyanika - rack plating - kuziziritsa - mankhwala mankhwala - kuyeretsa - akupera - otentha dip galvanizing watha.

Electrogalvanizing process flow: chemical degreasing - kuchapa madzi otentha - kutsuka - electrolytic degreasing - kutsuka madzi otentha - kutsuka - kuwononga mwamphamvu - kutsuka - electrogalvanized iron alloy - kutsuka - kutsuka - kuwala - passivation - kutsuka - kuyanika.

3. Kapangidwe kosiyanasiyana

Pali njira zambiri zopangira galvanizing yotentha. Pambuyo workpiece ndi degreasing, pickling, kuviika, kuyanika, etc., akhoza kumizidwa mu osungunuka nthaka kusamba. Monga zida zina zapaipi zotentha zimakonzedwa motere.

Electrolytic galvanizing imakonzedwa ndi zida za electrolytic. Pambuyo pa degreasing, pickling ndi njira zina, imamizidwa mu njira yothetsera mchere wa zinki, ndipo zida za electrolytic zimagwirizanitsidwa. Pakayendetsedwe ka mafunde abwino ndi oyipa, wosanjikiza wa zinc amayikidwa pa workpiece. .

4. Maonekedwe osiyana

Maonekedwe onse otentha-kuviika galvanizing ndi pang'ono rougher, amene adzatulutsa ndondomeko madzi mizere, kudontha zotupa, etc., makamaka pa mapeto a workpiece, amene ali silvery woyera lonse. Pamwamba wosanjikiza wa elekitirodi galvanizing ndi yosalala, makamaka chikasu wobiriwira, ndithudi, palinso zokongola, buluu-woyera, woyera ndi kuwala wobiriwira, etc. The workpiece lonse kwenikweni sikuwoneka nthaka tinatake tozungulira, agglomeration ndi zochitika zina.
