1.How kom ua rust tshem tawm?
Txhua yam xeb tawm: Quaj thiab zeb nplai raug tshem tawm los ntawm kev sib tsoo (Sandblasting (siab}}}} kub}}} kub} nrawm nrawm nrawm ntawm cov kab hlau sib tsoo). Hom qauv no yog tsim nyog rau cov kab hlau loj (xws li cov hlau hlau thiab cov hlau ntu). Tom qab Rust tshem tawm, qhov chaw ntawm nto yog qhov me me, uas txhim kho cov nplaum ntawm cov txheej txheem tiv thaiv tom ntej. (Sandblasting / txhaj tshuaj blasting ua tiav qhov zoo tshaj plaws Ruste tshem tawm cov txiaj ntsig, mus txog sa2.5, nrog zoo tsis muaj xeb.)
Tshuaj lom xeb tshem tawm: xeb yog muab tshem tawm los ntawm pickling (hydrochloric acid, sulfuric acid daws) los yog alkaline tu. Hom qauv no yog tsim nyog rau cov txheej txheem me me, cov txheej txheem xws li bolts thiab yeeb nkab fittings). Txawm li cas los xij, nws yog ib qho tseem ceeb kom yaug kom huv si nrog cov dej huv tom qab pickling tom qab kev kho mob "passivation" (xws li thov tus neeg caij passivating passivating passivating passivating Txwv tsis pub, cov residual acid ntawm cov hlau deg yuav nrawm corrosion.
2.Yog li cas tshem roj / av?
Cov hlau tuaj yeem ua paug nrog cov roj (xws li cov roj txiav) thiab hmoov av thaum ua thiab chaw cia khoom. Kev tu nrog cov kuab tshuaj organic (xws li dej cawv lossis roj av) lossis cov tshuaj ntxuav tes) yog qhov tsim nyog los xyuas kom meej tias cov roj dawb. Qhov no tuaj yeem txheeb xyuas tau txheeb xyuas tau siv "dej zaj duab xis xeem": Ncuav dej hla saum npoo tom qab tu. Yog tias cov yeeb yaj kiab dej ua ke ua rau tusyees tsis muaj kev tawg, cov roj tau raug tshem tawm.
3.Qhov dab tsi yog cov hom coating thiab cov yam ntxwv?
Anti - Cov xim corrosion: Tus nqi qis, daim ntawv thov yooj yim (txhuam, tshuaj xyuas cov xim; luv lub neej ntawm ib lub tsho tiv no (1-5 xyoos), xav tau kev ua ntu zus; nruab nrab huab cua tsis kam (yooj yim rau hnub nyoog sab nraud)
Hmoov txheej: kuab - dawb (ib puag ncig phooj ywg (50 {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}, cuam tshuam thiab kos, yuav tsum muaj qhov kev kho kub siab (180-200 degree), tsis haum rau loj / complex kev teeb tsa; Cov cuab yeej loj thawj coj
Hnyav {- Duty {{} Cov huab cua, acid thiab alkali, uas tuaj yeem tiv thaiv dej hiav txwv tsis tuaj yeem tiv thaiv dej hiav txwv); Tus nqi siab (chav tsev yog 3-10 zaug uas ntawm cov xim pleev xim zoo nkauj), thiab cov kev tsim kho siab (yuav tsum muaj kev txau ua)
4.Qhov kev txiav txim siab tseem ceeb hauv kev tsim kho?
Txheej Txheem Yuav Tsum Tau Txais Ntau Daim Ntawv Cog Lus: A primer (xws li Epoxy Primer) feem ntau thov kev tiv thaiv thiab lub hom phiaj zoo nkauj, xws li polyurethane toxat). Hnyav {{{{{{{{} Lub luag hauj lwm} Lub tsho tivthaiv yuav tsum muaj lub tsho tiv no nruab nrab (rau cov tuab ntxiv, xws li ntaub fiberglass).
Kev tswj cov txheej tuab: dhau lawm tuaj yeem ua rau cov txheej txheej ploj, thaum tuab tuab tuaj yeem ua rau tawg. Daim ntawv thov yuav tsum yog raws cov khoom yuav tsum tau (piv txwv li, tag nrho cov xaim hluav taws xob yuav tsum loj dua lossis sib npaug rau 200μm).
Zam kev cai thov: Kev thov yuav tsum tsis txhob ua rau cov nag hnub, thaum cov av noo ntau dua li 85%, lossis thaum sov dua (cov txheej txheem me me) thiab kho kom maj mam).
5.Qhov dab tsi yog cov hom phiaj txheej txheem thiab cov yam ntxwv?
Galvanizing (feem ntau siv):
Cov hau kev: kub {- dip galvanizing (ib qho nyias nyias
Cov txiaj ntsig: Cov zinc txheej muaj cov khoom siv tau muaj zog (sab nraum zoov lub neej ntawm 5,6}}}}
NCO TSEG: Yog tias tha xim yog xav tau tom qab Galvanizing, phosphating yuav tsum tau ua ua ntej ua ntej (txhawm rau txhim kho cov xim nplaum). Txwv tsis pub, cov txheej zinc yuav hnov qab zib nrog cov xim thiab ua rau nws mus tev tawm. Aluminium / zinc -}} aluminium alloy txheej:
Zinc -} Alloy Alloy Alloy Alloy Cleating (xws li}} av noo (xws li cov av nkos, ntau dua li cov khoom siv hiav txwv thiab cov khoom siv marine).
Qhov tsis zoo: Tus nqi yog 20% -30% siab dua zinc plating, thiab kev ua yog qhov nyuaj dua me ntsis (cov khoom siv tshwj xeeb yog yuav tsum tau).
Tin / chromium plating:
Tin Plating yog feem ntau siv rau cov khoom noj sib chwv steel (xws li cov kaus poom). Cov txheej tin yog tsis - kev lom thiab tiv taus rau cov kua qaub tsis muaj zog.
Chromium plating muaj ib qho nyuaj thiab hnav - Tsis tau siv rau kev ua kom zoo nkauj lossis hnav}}} Cov khoom lag luam thiab cov tshuab hluav taws xob). Txawm li cas los xij, nws corrosion resistance zoo siab rau kev ua pinhole- dawb (kev puas tsuaj rau lub plating tuaj yeem ua kom nrawm corrosion), ua rau muaj nqi siab dua.
