Hot dip galvanizing ndi njira yochizira pamwamba yomwe imaphatikizapo kumiza ziwalo zoyeretsedwa kale mumtsuko wa zinki kuti zigwirizane ndi kutentha kwambiri kuti zipange zokutira zinki Njira zitatu zopangira galvanizing dip ndi izi:
① Pamwamba pa chinthucho chimasungunuka ndi madzi a zinc, ndipo chitsulo chokhazikika chimasungunuka ndi madzi a zinc kuti apange gawo la aloyi yachitsulo.
② Ma ion a zinki mu aloyi wosanjikiza amafalikiranso ku matrix kuti apange zinki chitsulo mutual solution wosanjikiza; Chitsulo chimapanga aloyi yachitsulo cha zinki panthawi ya kusungunuka kwa zinc solution ndipo ikupitiriza kufalikira kumadera ozungulira Pamwamba pazitsulo zachitsulo za zinki zimakutidwa ndi zinc wosanjikiza, zomwe zimazizira ndi crystallizes kutentha kwa firiji kupanga zokutira. Pakali pano, kutentha kuviika galvanizing ndondomeko mabawuti wakhala kwambiri wangwiro ndi okhazikika, ndi makulidwe ❖ kuyanika ndi dzimbiri kukana angathe kukwaniritsa odana ndi dzimbiri zofunika zipangizo zosiyanasiyana makina. Komabe, pali mavuto otsatirawa pakupanga ndi kukhazikitsa makina amakina:
1. Pali zotsalira zazing'ono za zinc pa ulusi wa bawuti, zomwe zimakhudza kukhazikitsa,
2. Chikoka pa kugwirizana mphamvu zambiri zimatheka ndi kukulitsa machining chilolezo cha mtedza ndi kugogoda mmbuyo pambuyo plating kuonetsetsa kukwanira pakati pa otentha-kuviika kanasonkhezereka nati ndi bawuti. Ngakhale izi zimatsimikizira kukwanira kwa chomangira, kuyezetsa kwamakina kumachitika nthawi zambiri, zomwe zimakhudza mphamvu yolumikizira ikatha.
3. Zomwe zimakhudzidwa ndi mawotchi amagetsi amphamvu kwambiri: Zolakwika zotentha-kuviika galvanizing ndondomeko zingakhudze kulimba kwa mabawuti, ndi kutsuka kwa asidi pa nthawi ya galvanizing kungapangitse kuti hydrogen okhutira mu masanjidwewo a 10,9 giredi mkulu-mphamvu mabawuti. , kuonjezera kuthekera kwa hydrogen embrittlement. Kafukufuku wasonyeza kuti mawotchi katundu wa ulusi zigawo za mabawuti mkulu-mphamvu (giredi 8.8 ndi pamwamba) pambuyo otentha-kuviika galvanizing ndi mlingo winawake kuwonongeka.
Mechanical galvanizing ndi njira yomwe imagwiritsa ntchito mawonekedwe akuthupi, ma adsorption a mankhwala, ndi kugunda kwa makina kuti apange zokutira zachitsulo pamwamba pa chogwirira ntchito kutentha ndi kupanikizika. Pogwiritsa ntchito njirayi, zokutira zitsulo monga Zn, Al, Cu, Zn-Al, Zn-Ti, ndi Zn-Sn zimatha kupangidwa pazigawo zachitsulo, zomwe zimapereka chitetezo chabwino cha gawo lapansi lachitsulo. Makina opangira malata okha amatsimikizira kuti makulidwe a ulusi ndi ma grooves ndi owonda kuposa malo athyathyathya. Pambuyo plating, mtedza safuna kubwerera mmbuyo, ndipo mabawuti pamwamba M12 safuna ngakhale kusunga kulolerana. Pambuyo plating, sizimakhudza zoyenera ndi makina katundu. Komabe, tinthu kukula kwa nthaka ufa ntchito pokonza, kudyetsa kwambiri pa plating ndondomeko, ndi kudyetsa imeneyi mwachindunji zimakhudza kachulukidwe, flatness, ndi maonekedwe ❖ kuyanika, potero zimakhudza khalidwe ❖ kuyanika.
