Electroplating Vaaiga Aoao

Electroplating o le faʻagasologa o le faʻapipiʻiina o se mea manifinifi o isi metala poʻo mea faʻapipiʻi i luga o luga o nisi uʻamea poʻo isi mea e faʻaaoga ai le mataupu faavae o le electrolysis.. O le fa'aogaina o le eletise e fai sona sao i le puipuia o le fa'ama'iina o uamea (pei ole ele), fa'aleleia atili le fa'alavalava, conductivity eletise, malamalama malamalama, tetee a'a (kopa sulfate, ma isi.), ma le matagofie o vaega. E fa'apipi'i fo'i fa'alava i fafo o le tele o tupe.

E masani ona manifinifi vaega fa'aeletise, e amata mai i nai microns i le sefulu microns. E ala i le eletise, e mafai ona maua i luga o oloa fa'ainisinia teuteuga puipui ma galuega eseese, ma o vaega ua masaesae ma ua sese le masini e mafai foi ona toe faaleleia.

Fa'agasologa Fa'aeletise

Fa'avae e fa'apea:

(1) Faʻafesoʻotaʻi le uʻamea faʻapipiʻi i le anode, pe fa'aopoopo le masima solu o le u'amea fa'alavalava i le ta'ele;

(2) O le mea e faʻapipiʻiina e fesoʻotaʻi i le cathode;

(3) O le cathode ma le anode e fesoʻotaʻi i se vaifofo eletise e aofia ai ion lelei o le uamea faʻapipiʻi;

(4) A maeʻa ona faʻaogaina le eletise DC, o le uʻamea o le anode o le a tatalaina electrons, ma le lelei (uamea) ions e gaosia ions uamea i le electroplating fofo ua faaitiitia (maua electrons) i le cathode i atoms ma faaputuputu i luga o le pito i luga o le cathode (va'ai le ata i lalo). ).

Eseese Manaoga ma Galuega Fa'aeletise

(1) Ufiu apamemea: fa'aaogaina e fai ma fa'amuamua e fa'aleleia atili ai le fa'apipi'i ma le fa'a'ele'ele o le mea fa'aeletise. O le kopa e faigofie ona oxidized, ma ina ua uma oxidation, e le toe mafai e le verdigris ona faafoeina le eletise.

(2) Ufiufi nikeli: fa'aaogaina e fai ma fa'amuamua po'o se fa'aaliga e fa'aleleia atili ai le fa'a'ele'ele ma le fa'alavalava. O le ofuina o le u'amea nickel i faiga fa'aonaponei e sili atu nai lo le fa'apipi'i chrome. Manatua o le tele o oloa faaeletonika e le o toe faʻaogaina le nickel e fai ma faʻavae, aemaise lava ona o le nickel o le maneta, lea o le a aafia ai le intermodulation passive i le faatinoga o le eletise.

(3) Ufiufi siliva: E le gata i le teuteuga, e mafai ona faʻaleleia le faʻafesoʻotaʻi tetee o mea conductive. O le siliva e iai mea e sili atu ona lelei, e faigofie ona oxidize, ma fa'atautaia le eletise pe a uma ona fa'ama'iina.

(4) Palladium fa'apipi'i: Nickel e mafai ona mafua ai le dermatitis. Ua leva ona teena e le Iuni a Europa le faaulufale mai o meaafale o loo iai nikeli. Palladium o le u'amea sili ona lelei e suitulaga i le nikeli. Palladium e seasea, uamea lanu siliva-pa'epa'e, o se ituaiga o uamea taua e faaselau ona taugata nai lo le nickel. Aua e taugata le palladium, naʻo le palladium electroplating manifinifi e masani ona faʻaaogaina i Saina, ma le mafiafia o 0.1 ~ 0.2μm, lea e fa'aaogaina e fai ma fa'alavalava teuteu e tete'e i le corrosion ma se mea e fa'alilolilo ai le siliva i luga ole apa cupronickel.. Afai e mafiafia tele le palladium (sili atu 1 μm), ta'eta'ei e masani ona tupu.

(5) Ufi auro: Le vaega auro moni, faʻaopoopo i teuteuga, e mafai foi ona faʻaleleia le eletise eletise. E ui o le auro e sili ona mautu chemically, e sili foi ona taugata.

(6) Ufiufi auro Rose: auro mumu, lea ua sili ona lauiloa i teuteuga a tamaitai i tausaga talu ai nei. O le Rose auro o loʻo faʻaopoopoina moni le kopa i le auro, faia le auro sina mumu. E pei ona faaalia i le ata i lalo, le faatusatusaga lanu o 4 o lo'o fa'aalia ituaiga o fa'apipi'i gaogao zinc.

(7) auro fa'atusa / fa'atusa auro auro: Ona o le tau o le faʻapipiʻiina auro e maualuga tele, ua fa'aalia fo'i le auro fa'atusa i le maketi, ina ia mafai ai e oloa ma tau maualalo ona ausia le lanu o auro.O auro fa'atusa e moni lava na'o apamemea, e le o auro. O le apamemea e faigofie ona oxidized, o lea e tatau ai ona ufiufi se apa puipui i luga o le faʻaofuofu auro faʻatusa, ma varnish (Lacquer) e masani ona fa'aaogaina. O le auro fa'ata'ita'i fa'atusa e fa'apipi'iina apamemea ma varnish. Varnish o se ituaiga o vali kelu. A uma ona vali le mea faigaluega, o le lagona e le o lelei e pei o le ufi auro moni, ae o le tau ma le tau e mafai ona faaitiitia tele.

Are Plastic Caps the Unsung Heroes of Product Packaging?

Plastic caps may be the most inconspicuous yet critical components among the numerous things we buy and use on a daily basis. They silently guard the necks of bottles, performing numerous functions such as product protection, faigofie ole fa'aoga, and environmental recycling. Today, let’s look at these little plastic caps and how they play an important part in product packaging.
