1. Sinthani magawo a ndondomeko ya electroplating
Onetsetsani bwino pH mtengo wa mpukutu waukuluwaya wamalatakusamba, kafukufuku zikusonyeza kuti kukula kwa kusamba pH mtengo mwachindunji zimakhudza khalidwe la zitsulo waya ❖ kuyanika, kulamulira zosayenera pH mtengo adzachititsa ❖ kuyanika lotayirira.Phindu la pH likakhala lalikulu kuposa 3, zokutira waya zachitsulo zimakhala ndi ma dendrites abwino, ndipo pamwamba pake siwosalala.Kachulukidwe kakali pano akulamulidwa mosamalitsa.Kuchokera ku microscopic morphology, kukwezeka kwa kachulukidwe kakali pano, kukulirakulira kwa mbewu zosanjikiza za zinki, kusanjikizako kolingana ndi nthaka komwe kumayendera.
M'malo mwake, kuchulukira kwa ayoni kumapangitsa kuti nthaka ikhale yabwino kwambiri.Pansi pa chikhalidwe kuti nthaka wosanjikiza nthaka wandiweyani ndi yowala, khalidwe la nthaka wosanjikiza pa unit dera ayenera kufika 80g/m2, ndi magawo ndondomeko ayenera wokometsedwa motere: kachulukidwe panopa ndi 16-20A / dm2, misa ndende ya nthaka. Sulfate solution ndi 500g/L, ndipo pH yamtengo ndi 2.5-3.0.
2. Sinthani magawo a zojambula za tanki yamadzi
Mogwirizana kwambiri ndi zojambula zazing'ono zamapaipi ang'onoang'ono, chiwerengero chonse cha kuponderezana ndi 96.48%, kuchepetsa kupukuta kwa zinki.Mawaya onse amafa amapangidwa ndi tungsten chitsulo kufa ndi polycrystalline kufa.Mphepete mwa chingwe chogwirira ntchito cha waya wojambula ndi 12 ° ~ 16 °, ndipo kutalika kwa lamba wamba ndi 0,15 wa m'mimba mwake mwa waya, kuti zitsimikizidwe kuti kusinthika kwa zinki kumakhala kofanana ndi zitsulo waya gawo lapansi.
Dongosolo lozungulira loziziritsa limagwiritsa ntchito kupopera kuti kuziziritsa kufa, ndikuchotsa kutentha kochuluka kopangidwa ndi makina ojambulira pamakina othamanga kwambiri munthawi yake kuti zitsimikizire mtundu wa waya.Control zojambula ndondomeko magawo: kujambula liwiro 10 ~ 12m/s;Kuthamanga kwamphamvu 8 ~ 10N;Kuyeza kutalika 30km;Gawo lalikulu la mafuta ndi 3.5 ~ 4.5%;pH mtengo wa lubricant 7 ~ 8;Lubricant kutentha 30 ~ 40 ℃.
Pambuyo kukhathamiritsa ndondomeko, kupanga misa 0,80mm elekitirodiwaya wachitsulo chagalasiElectro kanasonkhezereka nthaka wosanjikiza khalidwe umalamulidwa mkati 80 ~ 90g/m2, nthaka wosanjikiza khalidwe kubalalitsidwa ndi kochepa kwambiri;Zotsatira zikuwonetsa kuti pafupifupi kulemera kwa zinc wosanjikiza ndi 14.5g/m2, kutayika kwa zinc wosanjikiza ndi zosakwana 5%, ndipo mphamvu yamakomedwe ya waya wachitsulo ndi 2300 ~ 2500MPa.Izo osati mogwira amazilamulira khalidwe nthaka wosanjikiza yaiwisi zitsulo waya, komanso amachepetsa zinyalala zosafunika ndi kupanga mtengo.
