kanasonkhezereka chitoliro ndi zitsulo chitoliro ndi otentha-kuviika kapena ❖ kuyanika electroplated pamwamba pake.Galvanizing kuonjezera dzimbiri kukana mipope zitsulo ndi kuwonjezera moyo wawo utumiki.Nkhaniyi ikufotokoza za machitidwe a mapaipi a malata:
1. Kukhathamiritsa kwa Sulfate Zinc Plating
Ubwino waukulu wa sulphate zinki plating ndi mphamvu yake yamakono yofikira 100% komanso kufulumira kwa kuyika kwake, komwe sikungafanane ndi njira zina zopangira zinki.Chifukwa chosakwanira crystallinity ❖ kuyanika, osauka kubalalitsidwa ndi mwakuya plating luso, ndi oyenera electroplating wa mapaipi ndi mawaya ndi osavuta akalumikidzidwa geometric.Njira yachikhalidwe ya sulphate zinc plating imakongoletsedwa ndi sulphate zinc plating process.Mchere waukulu kwambiri Zinc sulfate umasungidwa, ndipo zigawo zina zimatayidwa.Onjezani mchere wokwanira wachitsulo panjira yatsopanoyi kuti mupange zokutira zachitsulo kuchokera ku zokutira zachitsulo zoyambira.The restructuring wa ndondomeko osati amalimbikitsa ubwino mkulu panopa dzuwa ndi kudya mafunsidwe mlingo wa ndondomeko choyambirira, komanso kwambiri bwino kubalalitsidwa luso ndi mwakuya plating luso.M'mbuyomu, zigawo zovuta sizikanatha kupakidwa, koma tsopano mbali zonse zosavuta komanso zovuta zimatha kupakidwa, ndipo ntchito yotetezera imapangidwa bwino ndi 3-5 nthawi poyerekeza ndi zitsulo imodzi.Kupanga mchitidwe watsimikizira kuti pa electroplating mosalekeza wa mawaya ndi mapaipi, kukula kwa njere ya ❖ kuyanika ndi bwino, kuwala, ndi mafunsidwe mlingo mofulumira kuposa kale.Makulidwe opaka amakwaniritsa zofunikira mkati mwa mphindi 2-3.
2. Kutembenuka kwa Sulfate Zinc Plating
Zinc sulphate yekha, mchere waukulu wa sulphate zinki plating, amasungidwa sulphate electro galvanized iron alloy.Zigawo zina monga Aluminiyamu sulfate ndi alum (Potaziyamu alum) akhoza kuchotsedwa powonjezera sodium hydroxide kupanga insoluble hydroxide mpweya pa mankhwala plating njira;Pazowonjezera organic, ufa wa carbon activated umawonjezeredwa kuti adsorption ndi kuchotsa.Mayesowa amasonyeza kuti n'zovuta kuchotsa kwathunthu Aluminiyamu sulphate ndi Potaziyamu alum panthawi imodzi, zomwe zimakhudza kuwala kwa ❖ kuyanika, koma sizowopsa, ndipo zimatha kudyedwa nazo.Panthawiyi, kuwala kwa chophimba kumatha kubwezeretsedwanso ku yankho kudzera mu chithandizo, ndipo kutembenuka kungathe kutsirizidwa mwa kuwonjezera zomwe zili mu zigawo zomwe zimafunidwa ndi ndondomeko yatsopano.
3. Kuthamanga kwachangu komanso chitetezo chabwino kwambiri
Kuthekera kwaposachedwa kwa njira ya sulphate electroplating zinc iron alloy ndi yokwera mpaka 100%, ndipo kuchuluka kwake sikungafanane ndi njira iliyonse yopangira malata.Kuthamanga kwa chubu chabwino ndi 8-12 m / min, ndipo makulidwe a ❖ kuyanika ndi 2 m / min, zomwe zimakhala zovuta kukwaniritsa mukupitiriza galvanizing.Chophimbacho ndi chowala, chosakhwima, komanso chosangalatsa m'maso.Kuyesedwa molingana ndi njira yadziko lonse ya GB/T10125 "Artificial Atmosphere Test - Salt Spray Test" njira, maola 72, zokutira sizingasinthe;Pambuyo pa maola 96, dzimbiri laling'ono loyera linawonekera pamwamba pa zokutira.
4. Kupanga kwapadera kwaukhondo
The kanasonkhezereka chitoliro utenga sulphate electroplating kanasonkhezereka chitsulo aloyi ndondomeko, amene amakhala ndi perforation pakati kupanga mzere kagawo ndi kagawo, popanda entrainment yankho kapena kusefukira.Njira iliyonse yopangira zinthu imakhala ndi dongosolo lozungulira.Mayankho mu thanki iliyonse, kuphatikiza yankho la acid-base, electroplating solution, discharge and passivation solution, amangobwezerezedwanso ndikugwiritsidwanso ntchito popanda kutayikira kapena kutulutsa kunja kwa dongosolo.Mzere wopangira umangokhala ndi akasinja otsuka 5, omwe amatulutsidwa nthawi zonse pogwiritsa ntchito cyclic, makamaka popanga pomwe palibe madzi oyipa omwe amapangidwa pambuyo podutsa popanda kuyeretsa.
5. Zapadera za zida za electroplating
Electroplating wa mipope kanasonkhezereka, monga electroplating wa waya, wa electroplating mosalekeza, koma zipangizo ntchito electroplating ndi osiyana.Mphepete mwa plating wopangidwira waya wachitsulo wokhala ndi mizere yowonda, thupi lake ndi lalitali komanso lalitali koma losazama.Pa electroplating, waya wachitsulo amatuluka mu dzenje mumzere wowongoka
