Mtundu 1:zokutira (kapena kutembenuka) zokutira
Kuyika zitsulo ndi njira yosinthira pamwamba pa gawo lapansi pophimba ndi zigawo zoonda zachitsulo china monga zinki, faifi tambala, chromium kapena cadmium.
Kuyika zitsulo kumatha kupititsa patsogolo kulimba, kukangana pamwamba, kukana dzimbiri komanso mawonekedwe okongola a chinthucho. Komabe, zida zopangira plating sizingakhale zabwino kuthetsa zolakwika zachitsulo. Pali mitundu iwiri ikuluikulu ya plating:
Mtundu 2:Electroplating
Kuyika uku kumaphatikizapo kumiza chigawocho mu bafa lomwe lili ndi ayoni achitsulo kuti kupaka. Mphamvu yolunjika imaperekedwa kuchitsulo, ndikuyika ma ion pazitsulo ndikupanga wosanjikiza watsopano pamwamba pake.
Mtundu 3:Kuyika kwa electroless
Njirayi sigwiritsa ntchito magetsi chifukwa ndi autocatalytic plating yomwe imasowa mphamvu yakunja. M'malo mwake, chigawo chachitsulo chimamizidwa muzitsulo zamkuwa kapena nickel kuti ayambe njira yomwe imaphwanya zitsulo zachitsulo ndikupanga mgwirizano wa mankhwala.
Mtundu 4:Anodizing
Dongosolo la electrochemical lomwe limathandizira kuti pakhale kutha kwa anodic oxide kwanthawi yayitali, kowoneka bwino, komanso kukana dzimbiri. Kutsirizitsaku kumagwiritsidwa ntchito poviika chitsulo mu bafa la asidi electrolyte musanadutse mphamvu yamagetsi kupyola pakati. Aluminium imagwira ntchito ngati anode, yokhala ndi cathode yomwe imakhala mkati mwa thanki ya anodizing.
Ma ion a oxygen omwe amatulutsidwa ndi electrolyte kusakanikirana ndi maatomu a aluminiyamu kuti apange anodic oxide pamtunda wa workpiece. Chifukwa chake, anodizing ndi makutidwe ndi okosijeni olamulidwa kwambiri a gawo lapansi lachitsulo. Amagwiritsidwa ntchito nthawi zambiri kumaliza mbali za aluminiyamu, komanso amagwiranso ntchito pazitsulo zopanda chitsulo monga magnesium ndi titaniyamu.
Mtundu 5:Chitsulo akupera
Makina opera amagwiritsidwa ntchito ndi opanga kusalaza zitsulo pogwiritsa ntchito abrasives. Ndi imodzi mwamagawo omaliza pakupanga makina, ndipo imathandizira kuchepetsa kuuma kwapamwamba komwe kumasiyidwa pazitsulo kuchokera m'njira zam'mbuyomu.
Pali makina ambiri opera omwe alipo, iliyonse ikupereka magawo osiyanasiyana osalala. Makina opukusira pamwamba ndi omwe amagwiritsidwa ntchito kwambiri, koma palinso zopukutira zapadera zambiri zomwe zilipo monga Blanchard grinders ndi zopukutira zopanda pakati.
Mtundu 6:Kupukutira/Kutsuka
Ndizitsulo zopukutira, zida zonyezimira zimagwiritsidwa ntchito pochepetsa kuuma kwa chitsulo chachitsulo pambuyo popangidwa. Ufa wonyezimirawu umagwiritsidwa ntchito limodzi ndi mawilo omveka kapena achikopa kupukuta ndi kupukuta zitsulo.
Kupatula kuchepetsa kuuma kwa pamwamba, kupukuta kumatha kuwongolera mawonekedwe a gawo - koma ichi ndi cholinga chimodzi chokha chopukutira. M'mafakitale ena, kupukuta kumagwiritsidwa ntchito popanga ziwiya zaukhondo ndi zida.
Mtundu 7:Electropolishing
Njira ya electropolishing ndiyosiyana ndi njira ya electroplating. Electropolishing amachotsa ayoni zitsulo pamwamba pa zitsulo m'malo moziika. Musanagwiritse ntchito magetsi, gawo lapansi limamizidwa mu bafa la electrolyte. Gawo lapansi limasinthidwa kukhala anode, ma ions akuyenda kuchokera pamenepo kuti athetse zolakwika, dzimbiri, dothi ndi zina zotero. Zotsatira zake, pamwamba pake amapukutidwa komanso osalala, popanda zotupa kapena zinyalala.
Mtundu 8:Kujambula
Coating ndi liwu lalikulu lomwe limaphatikizapo zigawo zingapo zomaliza. Chosankha chodziwika bwino komanso chotsika mtengo ndicho kugwiritsa ntchito utoto wamalonda. Utoto wina ukhoza kuwonjezera mtundu ku chinthu chachitsulo kuti chikhale chowoneka bwino. Zina zimagwiritsidwanso ntchito poletsa dzimbiri.
Mtundu 9:Kupaka ufa
Kupaka ufa, mtundu wamakono wojambula, ndizomwe mungasankhe. Pogwiritsa ntchito electrostatic charge, imayika tinthu tating'onoting'ono pazigawo zachitsulo. Asanachiritsidwe ndi kutentha kapena cheza cha ultraviolet, tinthu tating'onoting'ono timaphimba zinthuzo. Njirayi ndiyofulumira komanso yothandiza popenta zinthu zachitsulo monga mafelemu anjinga, zida zamagalimoto ndi zopeka wamba.
Mtundu 10:Kuphulika
Kuphulika kwa abrasive kumagwiritsidwa ntchito kwambiri pazinthu zomwe zimafuna mawonekedwe a matte osasinthasintha. Ndi njira yotsika mtengo yophatikiza kuyeretsa pamwamba ndikumaliza ntchito imodzi.
Panthawi yophulika, mpweya wothamanga kwambiri umapopera pamwamba pazitsulo kuti zisinthe mawonekedwe ake, kuchotsa zinyalala ndi kupanga mapeto osalala. Itha kugwiritsidwanso ntchito pokonzekera pamwamba, kupaka ndi kupaka kuti atalikitse moyo wazinthu zachitsulo.
Mtundu 11:Kutsuka
Kutsuka ndi ntchito yofanana ndi yopukuta, kumapanga mawonekedwe ofanana ndi kusalaza kunja kwa gawo. Njirayi imagwiritsa ntchito malamba abrasive ndi zida zoperekera njere zolunjika pamwamba.
Zotsatira zimatha kusiyanasiyana malinga ndi momwe njirayo imagwiritsidwira ntchito ndi wopanga. Kusuntha burashi kapena lamba kumbali imodzi, mwachitsanzo, kungathandize kupanga m'mphepete pang'ono kuzungulira pamwamba.
Amangolangizidwa kuti agwiritsidwe ntchito pazinthu zosagwirizana ndi dzimbiri monga chitsulo chosapanga dzimbiri, aluminiyamu ndi mkuwa.
JINDALAI ndi gulu lotsogola lazitsulo ku China, titha kupereka zitsulo zonse zomaliza malinga ndi zosowa zanu, Perekani yankho loyenera kwambiri la polojekiti yanu.
Lumikizanani nafe tsopano!
