Poyerekeza ndi njira monga plating ndimankhwala pamwamba, kuyeretsa kukuwoneka ngati sitepe yosafunika.Ambiri a inu simungaganize zokonza ndalama zaphindu, chifukwa kuyeretsa kumangotengera nthawi ndi ndalama.Koma m'malo mwake, kuyeretsa ndikofunikira kwambiri pamtundu wazinthu ndipo kumakhudza kwambiri njira yotsatila.M'pofunika kufufuza zifukwa zomwe kuyeretsa kuli kofunika kwambiri.
Pamaso pa kutentha kutentha, pamwamba pa workpiece nthawi zambiri amawoneka oyera ndipo alibe chilema poyang'ana zithunzi.Komabe, muzochitika pambuyo pa chithandizo cha kutentha (monga nitriding), mavuto omwe amayamba chifukwa cha ukhondo wapansi panthaka amawululidwa.Kukonzanso kwa zinthu zosokonekera kumawononga nthawi ndi ndalama, ndipo zosokonekera sizingakonzedwenso nthawi zambiri.
Ngati pali vuto lililonse ngati limeneli, tiyenera kufufuza zomwe zimayambitsa mwamsanga.Zimango ndi zida zomwe zimayambitsa ziyenera kuyang'aniridwa poyamba: mtundu wazinthu, mawonekedwe a magawo, ndondomeko ya ng'anjo ya nitriding, ndi kukonza makina.Ngati zinthuzi zitha kuthetsedwa, chilemacho nthawi zambiri chimayamba chifukwa cha kusanjika kosawoneka-kutsekereza wosanjikiza pamwamba pa workpiece, zomwe zikutanthauza kuti ndizotsalira pagawo loyera lomwe limayambitsa vutolo.
Asanayambe chithandizo cha kutentha, gawolo limakhala ndi njira zambiri, zomwe zimapangitsa kusintha kwapamwamba.Pali mitundu iwiri ikuluikulu ya kusintha.
Kusintha kwamakina: kusinthika;extrusion;kugaya.
Kusintha kwa mankhwala: zigawo za phosphate (mwachitsanzo, zinki phosphating kuthandiza kujambula);anti-corrosion mankhwala;klorini, phosphorous kapena sulfure akhoza ali kuzirala lubricant, saponification madzimadzi, mafuta ndi zina;pamwamba mng'alu kuzindikira reagent.
Kodi kuyeretsa workpiece kuonetsetsa ukhondo pamwamba?
Nthawi zambiri 95-99% yamadzi yokhala ndi 1-5% yoyeretsa imagwiritsidwa ntchito kuyeretsa chogwirira ntchito, ndipo mtundu wamadzi ndiwofunikira kwambiri.Zonyansa m'madzi monga calcium, magnesium, sodium, potaziyamu, ndi kloridi zimatha kukhalabe pamwamba pa chogwirira ntchito pambuyo poyanika kuti apange chotchinga chotchinga, kotero kuti madzi a deionized okhala ndi ma conductivity mpaka 50 µS / cm ayenera kugwiritsidwa ntchito kupewa. mavuto pa kuyeretsa.
The amadzimadzi kuyeretsa dongosolo lili mitundu iwiri ya zigawo zikuluzikulu: chachikulu kuyeretsa wothandizila ndi pamwamba yogwira ntchito.
Chinthu chachikulu choyeretsera: Lili ndi zinthu zopanda organic kapena organic, monga alkali, phosphate, silicate, ndi amine.Ikhoza kusintha pH, kupereka mphamvu zamagetsi, ndi saponify mafuta.
Surface active agent: Lili ndi zinthu organic, monga alkyl benzene sulfonates ndi mafuta a mowa ethoxylates, ndipo limagwira ntchito yosungunula ndi kumwaza mafuta ndi mafuta.
Zofunikira zinayi zofunika pakuyeretsa kwamadzi ndikuyeretsa madzi, nthawi yoyeretsa, kutentha kutentha ndi njira yoyeretsera.
1. Kuyeretsa madzimadzi
Madzi oyeretsera ayenera kusinthidwa ndi gawo (mtundu wa zinthu), zonyansa zamakono ndi zotsatilamankhwala pamwamba.
2. Nthawi yoyeretsa
Nthawi yoyeretsera imadalira mtundu ndi kuchuluka kwa kuipitsidwa ndipo zingadalire ndondomeko yoperekedwa ya mzere woyeretsera kuti musasokoneze ntchito zotsatila.
3. Kutentha kutentha
Kutentha kwapamwamba kuyeretsa kumachepetsa kukhuthala kwa mafuta ndikusungunula mafuta, kupangitsa kuti izi zitheke mwachangu komanso zosavuta kuchotsa.
4. Njira yoyeretsera
Ntchito zosiyanasiyana zimayambitsidwa ndi zida zoyeretsera, monga: kufalikira kwa thanki, kusefukira, kupopera mbewu mankhwalawa, ndi akupanga.Njira yoyeretsera imadalira mtundu ndi mawonekedwe a gawo, kuipitsidwa ndi nthawi yoyeretsa yomwe ilipo.
Magawo anayiwa ayenera kusinthidwa kuti agwirizane ndi momwe zinthu zilili.Kupereka mphamvu zambiri (makina, matenthedwe kapena mankhwala) kapena nthawi yayitali yochizira imathandizira kuyeretsa.Komanso, amphamvu otaya kuyeretsa madzimadzi bwino kuyeretsa kwenikweni pa otsika kutentha.
Ndikoyenera kudziwa kuti zonyansa zina zimamangirizidwa bwino kwambiri ndipo sizingachotsedwe poyeretsa.Zowonongeka zotere zimatha kuchotsedwa kokha ndi njira monga kugaya, sandblasting, ndi pre-oxidation.
