Chithandizo cha Pickling Phosphating

Kodi pickling phosphating ndi chiyani
Ndi njira yopangira zitsulo pamwamba, pickling ndi kugwiritsa ntchito ndende ya asidi kuyeretsa zitsulo kuchotsa dzimbiri pamwamba.Phosphating ndikunyowetsa zitsulo zotsukidwa ndi asidi ndi phosphating yankho kuti apange filimu ya oxide pamwamba, yomwe ingateteze dzimbiri ndikuwongolera kumamatira kwa utoto kukonzekera sitepe yotsatira.

Kukoleza kuchotsa dzimbiri ndi peel ndiyo njira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale.Cholinga cha kuchotsa dzimbiri ndi kuchotsa khungu kumatheka ndi makina amavula haidrojeni opangidwa ndi asidi kusungunuka kwa okusayidi ndi dzimbiri.Zomwe zimagwiritsidwa ntchito pa pickling ndi hydrochloric acid, sulfuric acid ndi phosphoric acid.Asidi wa nitric sagwiritsidwa ntchito kawirikawiri chifukwa amatulutsa mpweya wa nayitrogeni woipa wa nitrogen dioxide pa pickling.Hydrochloric asidi pickling ndi oyenera ntchito kutentha otsika, sayenera upambana 45 ℃, ntchito ndende ya 10% mpaka 45%, ayeneranso kuwonjezera kuchuluka koyenera asidi mist inhibitor ndi koyenera.Sulphuric acid pa otsika kutentha pickling liwiro ndi wodekha, ayenera kugwiritsidwa ntchito mu sing'anga kutentha, kutentha 50 ~ 80 ℃, ntchito ndende ya 10% ~ 25%.Ubwino wa phosphoric acid pickling ndikuti sichidzatulutsa zotsalira zowononga (mochuluka kapena mochepera padzakhala Cl-, SO42- zotsalira pambuyo pa hydrochloric acid ndi pickling ya sulfuric acid), yomwe ili yotetezeka, koma kuipa kwa phosphoric acid ndikuti mtengo ndi wapamwamba, liwiro pickling ndi pang'onopang'ono, ambiri ntchito ndende ya 10% mpaka 40%, ndi kutentha mankhwala kungakhale kutentha wabwinobwino kwa 80 ℃.Mu pickling ndondomeko ntchito zidulo wosanganiza ndi njira zothandiza kwambiri, monga hydrochloric-sulfuric asidi osakaniza asidi, phospho-citric asidi osakaniza asidi.Kuchuluka koyenera kwa corrosion inhibitor kuyenera kuwonjezeredwa ku pickling, kuchotsa dzimbiri ndi njira yochotsera oxidation tank.Pali mitundu yambiri ya corrosion inhibitors, ndipo kusankha ndikosavuta, ndipo ntchito yake ndi kuletsa dzimbiri zachitsulo ndikuletsa "hydrogen embrittlement".Komabe, pamene pickling "hydrogen embrittleness" workpieces tcheru, kusankha dzimbiri zoletsa ayenera kusamala makamaka, chifukwa zina zoletsa dzimbiri ziletsa zimene maatomu awiri wa haidrojeni mu mamolekyu wa haidrojeni, ndicho: 2[H]→H2↑, kuti ndende. maatomu a haidrojeni pamwamba pa chitsulo akuwonjezeka, kukulitsa chizolowezi cha "hydrogen embrittleness".Choncho, m'pofunika kukaonana ndi dzimbiri deta Buku kapena kuchita "hydrogen embrittlements" mayeso kupewa ntchito zoopsa dzimbiri zoletsa.

Kupambana kwaukadaulo woyeretsa mafakitale - kuyeretsa laser kobiriwira
The otchedwa laser kuyeretsa luso amatanthauza ntchito mkulu mphamvu laser mtengo kuti irradiate pamwamba pa workpiece, kuti pamwamba dothi, dzimbiri kapena ❖ kuyanika yomweyo evaporation kapena kuvula, mkulu-liwiro ndi ogwira kuchotsa chinthu pamwamba. chomata kapena ❖ kuyanika pamwamba, kuti akwaniritse njira yoyera.Ndi ukadaulo watsopano wotengera kuyanjana kwa laser ndi zinthu, ndipo uli ndi zabwino zodziwikiratu poyerekeza ndi njira zachikhalidwe zoyeretsera monga kuyeretsa kwamakina, kuyeretsa kwadzidzidzi kwamankhwala, kuyeretsa kwamadzi olimba kwambiri, kuyeretsa pafupipafupi kwa ultrasonic.Ndizothandiza, zachangu, zotsika mtengo, zowotcha zazing'ono komanso zonyamula makina pagawo laling'ono, komanso zosawononga pakuyeretsa;Zinyalala zikhoza zobwezerezedwanso, palibe zoipitsa chilengedwe otetezeka ndi odalirika, sikuwononga thanzi la woyendetsa akhoza kuchotsa makulidwe osiyanasiyana osiyanasiyana, zigawo zosiyana za ❖ kuyanika mlingo kuyeretsa ndondomeko n'zosavuta kukwaniritsa kulamulira basi, kuyeretsa kutali ndi zina zotero.

Ukadaulo woyeretsera wa laser wobiriwira komanso wopanda kuipitsa umathetsa kutsutsa kwa chilengedwe kwaukadaulo wamankhwala a pickling phosphating.Ukadaulo woteteza zachilengedwe komanso ukadaulo woyeretsa zobiriwira - "kuyeretsa laser" kudayamba ndikuwuka ndi mafunde.Kafukufuku wake ndi chitukuko ndi kugwiritsa ntchito kumabweretsa kusintha kwatsopano kwa mtundu woyeretsa mafakitale ndikubweretsa mawonekedwe atsopano kumakampani opanga mankhwala padziko lonse lapansi.
