Kuchiza pamwamba pa mipope yachitsulo yopanda msoko

Ⅰ- AsidiKutola

1.-Tanthauzo laAcid-Pickling: Acid amagwiritsidwa ntchito pochotsa iron oxide sikelo pamlingo wina, kutentha, ndi liwiro, zomwe zimatchedwa pickling.

2.- Asidi -Pickling classification: Malinga ndi mtundu wa asidi, wagawidwa mu pickling sulfuric acid, pickling hydrochloric acid, pickling nitric acid, ndi hydrofluoric acid pickling.Osiyana TV ayenera kusankhidwa pickling zochokera zinthu za zitsulo, monga pickling mpweya zitsulo ndi asidi sulfuric ndi hydrochloric acid, kapena pickling zitsulo zosapanga dzimbiri ndi osakaniza nitric asidi ndi hydrofluoric acid.

Malingana ndi mawonekedwe a chitsulo, amagawidwa kukhala pickling waya, pickling, pickling zitsulo, pickling, etc.

Kutengera ndi mtundu wa zida zonyamula, zimagawidwa m'matanki, pickling mosalekeza, pickling mosalekeza, ndi pickling nsanja.

3.- Mfundo ya pickling asidi: Kutola asidi ndi njira yochotsera mamba a iron oxide pazitsulo pogwiritsa ntchito njira za mankhwala, motero amatchedwanso chemical acid pickling.Masikelo achitsulo okusayidi (Fe203, Fe304, Fe0) opangidwa pamwamba pa mipope yachitsulo ndi osayidi wofunikira omwe sasungunuka m'madzi.Akamizidwa mumchere wa asidi kapena kupopera ndi madzi a asidi pamwamba, osayidi wofunikirawa amatha kusintha kusintha kwa mankhwala ndi asidi.

Chifukwa cha kutayikira, porous, ndi kusweka kwa sikelo ya okusayidi pamwamba pa chitsulo chopangidwa ndi mpweya kapena chitsulo chochepa cha aloyi, kuphatikizidwa ndi kupindika mobwerezabwereza kwa sikelo ya oxide pamodzi ndi chitsulo chamzere pakuwongola, kuwongola, kuwongolera, komanso kuyenda pickling mzere, izi pore ming'alu kumawonjezera ndi kukulitsa.Chifukwa chake, asidi amadzimadzi amakumana ndi sikelo ya oxide monga momwe amachitira komanso amalumikizana ndi chitsulo chapansi panthaka kudzera m'ming'alu ndi pores.Ndiko kunena kuti, kumayambiriro kwa kutsuka kwa asidi, machitidwe atatu a mankhwala pakati pa chitsulo okusayidi sikelo ndi chitsulo chachitsulo ndi njira ya asidi imachitika nthawi imodzi mamba a Iron oxide amakumana ndi mankhwala ndi asidi ndipo amasungunuka (kusungunuka) Chitsulo chachitsulo chimakhala ndi asidi. kupanga mpweya wa haidrojeni, womwe umachucha mu sikelo ya oxide (mawotchi peeling zotsatira) The kwaiye atomiki haidrojeni amachepetsa chitsulo oxides kuti ferrous oxides amene sachedwa zimachitikira asidi, ndiyeno amachitira ndi zidulo kuchotsedwa (kuchepetsa).

Ⅱ-Passivation/Kuletsa/Kuletsa

1.- Mfundo ya Passivation: The passivation mechanism ingathe kufotokozedwa ndi chiphunzitso chochepa cha filimu, chomwe chimasonyeza kuti kusuntha kumachitika chifukwa cha kugwirizana pakati pa zitsulo ndi zinthu za okosijeni, zomwe zimapanga filimu yopyapyala kwambiri, yowundana, yophimbidwa bwino, komanso yowoneka bwino pazitsulo.Kanemayu amakhala ngati gawo lodziyimira pawokha, nthawi zambiri amakhala ndi zitsulo zokhala ndi okosijeni.Zimagwira ntchito yolekanitsa zitsulo kuchokera ku zowonongeka zowonongeka, kuteteza zitsulo kuti zisagwirizane ndi zowonongeka zowonongeka, potero zimayimitsa kusungunuka kwachitsulo ndikupanga dziko lopanda pake kuti likwaniritse zotsatira zotsutsana ndi zowonongeka.

2.- Ubwino wa passivation:

1) Poyerekeza ndi njira zachikhalidwe zosindikizira thupi, chithandizo cha passivation chimakhala ndi mawonekedwe osachulukitsa makulidwe a chogwirira ntchito ndikusintha mtundu, kuwongolera kulondola komanso kuwonjezereka kwa chinthucho, kupangitsa kuti ntchito ikhale yosavuta;

2) Chifukwa cha kusakhazikika kwa njira yopititsira patsogolo, wothandizila amatha kuwonjezeredwa mobwerezabwereza ndikugwiritsidwa ntchito, zomwe zimapangitsa moyo wautali komanso ndalama zambiri.

3) Passivation amalimbikitsa mapangidwe mpweya mpweya dongosolo passivation filimu pamwamba zitsulo, amene ali yaying'ono ndi okhazikika mu ntchito, ndipo ali kudzikonza yekha mphamvu mu mlengalenga nthawi yomweyo.Choncho, poyerekeza ndi chikhalidwe njira ❖ kuyanika odana rust mafuta, ndi passivation filimu yopangidwa ndi passivation ndi khola ndi dzimbiri kugonjetsedwa.Zambiri mwazomwe zimapangidwira mu oxide wosanjikiza zimagwirizana mwachindunji kapena mwanjira ina ndi njira ya okosijeni yamafuta.Mu kutentha osiyanasiyana 800-1250℃, kutenthetsa kwa okosijeni pogwiritsa ntchito mpweya wouma, mpweya wonyowa, kapena mpweya wa madzi kumakhala ndi magawo atatu osalekeza.Choyamba, mpweya wa m'mlengalenga umalowa m'kati mwa oxide wosanjikiza, ndiyeno mpweya umafalikira mkati mwa silicon dioxide.Ikafika pa mawonekedwe a Si02-Si, imakumana ndi silicon kupanga silicon dioxide yatsopano.Mwanjira imeneyi, njira yopitilira ya kufalikira kwa okosijeni imachitika, zomwe zimapangitsa kuti silicon yomwe ili pafupi ndi mawonekedwewo isinthe mosalekeza kukhala silika, ndipo wosanjikiza wa oxide umakula molowera mkati mwa silicon wafer pamlingo wina.

Ⅲ- Phosphating

Chithandizo cha Phosphating ndi mankhwala omwe amapanga filimu (phosphating film) pamwamba. Njira yothandizira phosphating imagwiritsidwa ntchito makamaka pazitsulo zazitsulo, ndi cholinga chopereka filimu yotetezera kuti iwononge zitsulo kuchokera ku mpweya ndikuletsa dzimbiri;Itha kugwiritsidwanso ntchito ngati choyambira pazinthu zina musanapente.Ndi filimuyi ya phosphating iyi, imatha kupititsa patsogolo kumamatira ndi kukana kwa dzimbiri kwa wosanjikiza wa utoto, kupititsa patsogolo zokongoletsa, ndikupanga chitsulo chowoneka bwino kwambiri.Itha kugwiranso ntchito yopaka mafuta munjira zina zozizira zachitsulo.

Pambuyo pa chithandizo cha phosphating, chogwiriracho sichidzawotcha kapena dzimbiri kwa nthawi yayitali, chifukwa chake kugwiritsa ntchito mankhwala a phosphating ndikokulirapo komanso njira yochizira yachitsulo yomwe imagwiritsidwa ntchito kwambiri.Amagwiritsidwa ntchito kwambiri m'mafakitale monga magalimoto, zombo, ndi kupanga makina.

1.- Gulu ndi kugwiritsa ntchito phosphating

Nthawi zambiri, chithandizo chapamwamba chimapereka mtundu wosiyana, koma chithandizo cha phosphating chimatha kutengera zosowa zenizeni pogwiritsa ntchito ma phosphating osiyanasiyana kuti awonetse mitundu yosiyanasiyana.Ichi ndichifukwa chake nthawi zambiri timawona chithandizo cha phosphating mu imvi, mtundu, kapena wakuda.

Iron phosphating: pambuyo phosphating, pamwamba adzawonetsa utawaleza mtundu ndi buluu, choncho amatchedwanso mtundu phosphorous.The phosphating yankho makamaka amagwiritsa molybdate monga zopangira, amene kupanga utawaleza phosphating filimu pamwamba pa zipangizo zitsulo, komanso makamaka ntchito kupenta wosanjikiza pansi, kuti akwaniritse kukana dzimbiri ya workpiece ndi kusintha adhesion. wa zokutira pamwamba.

JINBAICHENG ndi kutsogolera fakitale zitsulo chitoliro ku China, Tingathe kutulutsa ndi kupereka mosalekeza zitsulo chitoliro, welded chitoliro, utsa chitoliro, gi chitoliro ndi padziko Acid-Pickling, Passivation, ndi Phosphating.Timapereka ntchito zofananira ndipo tidzakupatsani yankho labwino kwambiri pamapulojekiti anu.Lumikizanani nafe pamtengo wabwino kwambiri:https://www.sdjbcmetal.com/steel-pipe-series/ imelo:jinbaichengmetal@gmail.com kapena pa WhatsApphttps://wa.me/18854809715
