Kaʻina Hoʻopalapala

ʻO ke kaʻina hana electroplatingHe ala ia o ka uhi ʻana i kahi conductor me kahi papa metala me ka hoʻohana ʻana i ke kumu o ka electrolysis.ʻO ka electroplating e pili ana i kahi ʻano hana ʻili kahi e hoʻohana ʻia ai ka metala kumu e hoʻopaʻa ʻia e like me ka cathode i loko o kahi wai paʻakai i loaʻa i ka metala i hoʻopaʻa ʻia, a waiho ʻia nā cations o ka metala i hoʻopaʻa ʻia i loko o ka hopena plating ma luna o ka ʻili. metala kumu ma o ka electrolysis e hana i ka uhi.

ʻOkoʻa nā waiwai o ka uhi ʻana mai ka metala kumu a loaʻa nā ʻano hou.E like me ka hana o ka uhi ʻana, ua māhele ʻia i ka uhi pale, ka hoʻonaninani a me nā mea hana ʻē aʻe.

I ka wā electroplating, hoʻohana ʻia ka metala paʻa a i ʻole nā ​​​​mea hiki ʻole ke hoʻohana ʻia e like me ka anode, hoʻohana ʻia ka mea hana e hoʻopaʻa ʻia e like me ka cathode, a ua hoʻemi ʻia nā cation o ka metala i hoʻopaʻa ʻia ma luna o ka ʻili o ka mea hana e hoʻopaʻa ʻia e hana i kahi papa plated. .Hiki iā ia ke hoʻonui i ka pale ʻana o ka metala (ʻo ka metala ka uhi ʻana i ka nui o ka corrosion-resistant metal), hoʻonui i ka paʻakikī, pale i ka ʻaʻahu, hoʻomaikaʻi i ka conductivity, smoothness, heat resistance and surface beauty.

Kumukūʻai

ElectroplatingHe kaʻina hana electrochemical a me ka hana redox.ʻO ke kaʻina hana maʻamau o ka electroplating ʻo ka hoʻoinu ʻana i ka ʻāpana i loko o kahi hopena o nā paʻakai metala e like me ka cathode, ka pā metala e like me ka anode,after ua hoohuliia ka mana DC, ka mea i makemake 'ia e waiho ma ka aoao.

ChoʻolāʻauProcess

ʻO ka mea maʻamau, loaʻa i ʻekolu mau pae o ka pre-plating pretreatment, electroplating a me ka post-plating treatment.

Hoʻopau kaʻina hana: 1. Pickling → piha piha electroplating

ʻO ke keleawe → ka hoʻololi ʻana i ke kumu → ka hoʻohaʻahaʻa ʻana i ka waika → ka holoi ʻana i ka lua → ka micro-etching → ke kula kiʻekiʻe → pickling → ka hoʻoheheʻe ʻana i ke tin → ka holoi ʻana i ka lua 2, ka holoi ʻana kūʻē → ka ʻohi → ka hoʻoheheʻe keleawe → ka holoi ʻana i ka lua → ka nickel plating → ka holoi ʻana i ka pae 2 ʻakika citric → ka uhi gula → hana hou → pae 2-3 holoi wai maʻemaʻe → hoʻomaloʻo.

Kaʻina hana electroplatingo ka pūpū plastik

ʻO ka holoi ʻana i ka wai. hoʻomaloʻo no ka nānā ʻana.
