Electrogalvanizing VS. Kutentha-kuviika Galvanizing

Malinga ndi ziwerengero, chitsulo ndi chosavuta kuchita dzimbiri mumlengalenga, m'madzi kapena m'nthaka, ndipo kuwonongeka kwapachaka komwe kumachitika chifukwa cha dzimbiri kumapanga pafupifupi 1/10 ya zitsulo zonse. Kuti apange pamwamba pa zomangira kukhala ndi ntchito zina zapadera ndikuwapatsa mawonekedwe okongoletsera, nthawi zambiri amathandizidwa ndi electrogalvanizing.

Electrogalvanizing

Electrogalvanizing ndi njira yomwe imagwiritsa ntchito zokutira zinki kuchitsulo kapena chitsulo pogwiritsa ntchito magetsi. Mfundoyi imaphatikizapo kumiza gawolo kuti likhale ndi yankho lomwe lili ndi ayoni a zinki. Mphamvu yamagetsi ikadutsa mu electrolyte, ayoni a zinki amachepetsedwa pamwamba pa cathode, ndikuyika gawo lochepa la zinki. Makulidwe ndi kufanana kwa zokutira kungawongoleredwe ndendende mwa kusintha nthawi ya ndondomekoyi, kachulukidwe kameneka, komanso kapangidwe ka electrolyte. Njirayi imalola kutsirizitsa kowala, kosalala, komanso kokongola, ndi zokutira zomwe zimayambira pa 5 mpaka 30 ma micrometer.

Mawonekedwe a zokutira zokhala ndi ma electrogalvanized amaphatikizira kumamatira bwino kwambiri kuzitsulo zoyambira, zomwe zimapereka kukana kwa dzimbiri, makamaka m'malo ovuta kwambiri. Unifolomu ndi makulidwe olamuliridwa amatsimikizira mawonekedwe osasinthika, kuti akhale abwino kwa magawo omwe amafunikira kumaliza kwapamwamba. Komabe, zokutira zoonda kwambiri zimatanthawuza kuti electrogalvanizing singapereke mlingo wofanana wa chitetezo cha makina monga kutentha kwa dip galvanizing, ndipo ikhoza kuwonongeka mosavuta chifukwa cha abrasion ndi kuyaka. Ngakhale izi, ndondomekoyi imadziwika kuti imatha kupanga zabwino, ngakhale zokutira zomwe zimapangitsa kuti zinthuzo ziwoneke bwino.

Minda yomwe ikukhudzidwa ndi electrogalvanizing ikuchulukirachulukira. Kugwiritsa ntchito zinthu za fasteners kwafalikira pakupanga makina, zamagetsi, zida zolondola, mankhwala, zoyendera, zamlengalenga, ndi zina zambiri, zomwe ndizofunikira kwambiri pachuma chadziko.

Kutentha-kuviika galvanizing

Hot-dip galvanizing ndi njira yotetezera dzimbiri pomwe zitsulo zotsukidwa ndi kukonzedwa kapena zigawo zachitsulo zimamizidwa mumtsuko wa zinki wosungunuka pafupifupi 450°C (842°F). Zinc imakhudzidwa ndi chitsulo, ndikupanga zigawo zingapo zazitsulo zachitsulo pamwamba pazitsulo, zotsatiridwa ndi zinki zoyera. Chomangira chachitsulo ichi chimapanga zokutira zolimba komanso zolimba. Makulidwe a zokutira zinki amadzilamulira okha ndipo nthawi zambiri amachokera ku 45 mpaka 275 ma micrometer, kutengera makulidwe a zinthu zoyambira. Nthawi yomizidwa ndi kuzizira mutatha kuchotsedwa mubafa kungakhudze maonekedwe ndi maonekedwe a zokutira zomaliza, zomwe nthawi zambiri zimabweretsa khalidwe lopakapaka kapena crystalline.

Mawonekedwe a zokutira zamalati otentha amaphatikiza kukhazikika kwapadera komanso kukana kwa dzimbiri kwanthawi yayitali, komwe kumatha kwazaka zambiri ngakhale m'malo ovuta. Zinki wandiweyani wosanjikiza umapereka chitetezo champhamvu pakuwonongeka kwamakina, monga mikwingwirima ndi mikwingwirima, ndipo imakhala ngati nsembe ya anode, yomwe imawononga makamaka kuteteza chitsulo chapansi. Chophimbacho chimakhalanso ndi kutentha kwabwino, ngakhale kuti chingakhudzidwe ndi kutentha kwambiri. Maonekedwe owoneka bwino, achitsulo otuwa a zokutira amatha nyengo pakapita nthawi mpaka patina ya matte imvi, zomwe sizimasokoneza chitetezo chake. Kuonjezera apo, ndondomekoyi ndi yotsika mtengo kwa zinthu zazikulu ndi zolemetsa, chifukwa zimapereka yankho lokhalitsa lomwe limafuna chisamaliro chochepa.

Kutentha kwa dip galvanizing kumagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana, makamaka zomwe zimakhudzana ndi nyumba zakunja ndi zomangamanga, komwe kumayang'aniridwa ndi zinthu zofunika kwambiri. Nthawi zambiri amagwiritsidwa ntchito pazitsulo zomangira, milatho, njanji zapamsewu waukulu, mizati yothandizira, ndi zida zina zomangira. Njirayi ndi yotchukanso popanga zida zaulimi, makina a mafakitale, ndi kayendedwe ka mayendedwe, kuphatikizapo njanji za njanji ndi zotengera zotumizira. Chifukwa cha kuthekera kwake kupereka chitsiriziro cholimba, chokhazikika, komanso chovomerezeka mwamawonekedwe, galvanizing yotentha ndi chisankho chomwe chimakondedwa pakugwiritsa ntchito kulikonse komwe kumafuna chitetezo chodalirika komanso chokhalitsa ku dzimbiri.

Zikomo powerenga, ngati mukufuna kuwona zambiri zomwe timapereka mutha kutsatira maulalo pansipa!
