Hlau coated qhov chaw

Covmetallic txheejyog txheej txheem ntawm kev npog cov khoom siv nrog ib txheej ntxiv ntawm cov hlau thiab alloys kom tsis txhob muaj corrosion.Ntxiv nrog rau kev tiv thaiv kom tsis txhob deterioration, cov xim hlau txheej txhim kho cov khoom siv kho tshuab, lub cev, thiab kev zoo nkauj ntawm qhov chaw nws siv (Substrate).Muaj ntau txoj hauv kev kom ua tiav cov txheej txheem hlau ntawm qhov chaw, suav nrog electrochemically, tshuaj, thiab mechanically.

Zinc, cadmium, aluminium, chrome, npib tsib xee, thiab nyiaj yog cov hlau uas siv rau hlau txheej.Txawm li cas los xij, Zinc yog qhov ntau tshaj plaws hauv kev coj ua ntawm kev tsim khoom lag luam.

Kab lus no yuav tshuaj xyuas ntau cov txheej txheem hlau txheej, suav nrogelectroplating, galvanizing, hmoov txheej, thermal spraying, painting, thiab hard steel txheej, nrog rau lawv cov txiaj ntsig.

Hom Hom Hlau Txheej

1.          Electroplating

Electroplating yog txheej txheem ntawm kev tsim ib txheej nyias ntawm txheej hlau ntawm lub substrate nto los ntawm electrolysis.Cov khoom siv substrate ua haujlwm raws li cathode, thiab cov khoom siv txheej txheej raws li anode hauv txheej txheem.Aqueous daws ntawm acids, bases, los yog ntsev yog siv los ua qhov tam sim no.Ntawm no, cov khoom siv coated yuav tsum muaj nyob rau hauv cov tshuaj aqueous.

Cov khoom siv txheej txheej ions mus rau cathode raws li hluav taws xob siv rau cov electrodes, uas lawv tso ib txheej.Txoj kev no feem ntau yog siv rau hauvzinc platingntawm cov khoom siv ferrous.

Kev teeb tsa electroplating

Qhov saum npoo yuav tsum tau sib npaug nrog cov khoom tso tawm los ntawm anode.Lub ntim ntim tau cuam tshuam los ntawm ntau qhov sib txawv, suav nrog qhov ceev tam sim no, lub sijhawm electrolysis, thiab lwm yam.Cia peb pom qhov no siv qhov sib npaug sib luag.

Qhov ntim ntawm cov hlau plated (V) = KI t

Qhov twg,

K = electrochemical sib npaug tas li, uas txawv ntawm electrodes thiab electrolyte hom

I = tam sim no dhau los ntawm electrolysis (A)

t = lub sij hawm ntawm electrolysis (sec)

Rau cov txheej txheem zoo, lub substrate yuav tsum tau ntxuav kom tsim nyog kom tshem tawm xeb, roj, slags, thiab lwm yam deg imperfection ua ntej yuav pib nrog electroplating.

2.          Galvanization

Galvanized qhov chaw

Nws yog txheej txheem txheej txheej hlau ntau tshaj plaws uas zinc yog coated ntawm steel lossis hlau los tiv thaiv corrosion.Yog tias koj tau pom tias txhua yam khoom siv hlau muaj qhov ci ntsa iab, ci ntsa iab nyiaj ntawm lawv qhov chaw, cov xim ntawd yog tshwm sim los ntawm galvanization thiab hu ua galvanized steel.Cov khoom yog galvanized los ntawm dipped rau hauv ib tug kub zinc tov, uas tsim ib tug nyias txheej.

Nyob rau hauv tus txheej txheem ntawm kub-dipping galvanization, lub hauv paus hlau ntxuav tau dipped (tom qab nws mus txog ze rau lub melting point ntawm zinc) rau hauv ib tug molten zinc da dej.Thaum kawg, txheej txheej tsis muaj zog thiab tsis sib xws yog tsim los ntawm kev khiav cov nplooj ntawv los ntawm cov chais tam sim ntawd thaum txheej txheej.Hlau txheej nrog galvanization yog ib qho pheej yig heev, yooj yim, thiab ceev cov txheej txheem uas muaj corrosion kuj.

Cov khoom siv thiab cov khoom siv ua liaj ua teb, tsheb, rooj tog, kev tsim kho, thiab ntau lwm yam khoom yog tag nrho cov txheej txheem galvanization.

3.          Hmoov txheej

Covhmoov txheejtxoj kev siv hluav taws xob hluav taws xob siv hluav taws xob los siv cov hmoov qhuav, xim hlau txheej rau cov khoom siv saum npoo.Cov hmoov muaj cov hmoov ua kom zoo ntawm cov xim xim uas muab cov xim zoo nkauj.

Qhov saum npoo ntawm cov khoom uas yuav coated yog ntxuav nyob rau hauv thawj theem, qhov twg plua plav, xeb, slags, thiab lwm yam pa phem raug tshem tawm siv cov kua qaub cleansing los yog tsuas distilled dej, nyob ntawm seb lub nto huv si thiab ua tiav cov kev xav tau zoo.Cov txheej txheem ntxuav kuj tseem ua kom cov nplaum nplaum ntawm qhov chaw kom cov txheej yuav ua tau zoo dua.

Hmoov coated ib feem

Nyob ntawm daim ntawv thov kawg, cov hmoov yog txau rau saum npoo av, los yog cov khoom yog submerged hauv cov kua nrog cov hmoov uas tau muab tshem tawm.Tom qab ntawd, cov khoom yog rhuab kom cov hmoov yaj thiab lo rau lub hau kom ruaj ntseg.

Cov rooj tog hlau feem ntau muaj cov hmoov txheej siv los tiv thaiv xeb los ntawm kev sib sau.Nws yog ib txoj kev siv nyiaj uas ua rau cov khoom thiab cov khoom siv tau ntev dua.

4.          Xim txheej

Xim-coated hlau nto.

"Metallic xim txheej" yog hais txog kev siv ntau yam kua xim rau cov khoom siv.Cov txheej txheem ntawm kev tsim cov hlau nyias txheej uas tiv thaiv corrosion yog cov tsoos heev.Txawm li cas los xij, kev tsim cov xim yog ib qho tseem ceeb hauv kev ua haujlwm zoo li cas.Yog li ntawd, kev tsim cov xim sib txawv yuav tsum tau ua raws li cov khoom siv, qhov chaw raug, thiab cov kev xav tau ua haujlwm.

Cov xim txheej tsis tshua muaj zog dua li lwm cov txheej txheem xim hlau uas peb tau tshuaj xyuas vim tias nws nyiam hnav tom qab ib ntus.Txawm li cas los xij, nws tseem yog ib txoj hauv kev zoo heev los ua cov khoom thiab cov khoom uas yuav raug ntsia sab hauv tsev corrosion-resistant.

5.          Thermal txau

Thermal txau txheej yog nto moo tshaj plaws rau cov hlau txheej ntawm steel qauv.Cov hlau siv hauv cov tshuab me me thiab loj xws li kev tsheb ciav hlau, kev tsheb ciav hlau, thiab cov tsev steel yog raug rau ib puag ncig thiab xav tau kev tiv thaiv zoo tiv thaiv xeb.Vim lawv qhov loj me, cov qauv no nyuaj rau galvanize, electroplate, lossis lub tsho tiv no nrog cov hlau tiv thaiv ntawm lwm txoj kev.Tab sis siv cov txheej txheem thev naus laus zis, nws tuaj yeem ua cov txheej txheem hlau nrog zinc, aluminium, lossis zinc-aluminium alloys.

Thermal txau ua haujlwm

Kev ntxuav yog ua tiav hauv thawj theem los txhim kho qhov nplaum nplaum thiab tshem tawm qhov tsis zoo ntawm qhov chaw.Tom ntej no, rab phom txau nrog lub tshav kub (cov pa roj pa lossis hluav taws xob arc) yog pub nrog cov hmoov hlau los yog cov ntaub ntawv hlau.Tom qab ntawd cov kua Zinc lossis txhuas yog txau rau ntawm qhov chaw siv lub dav hlau compressed.Aluminium yuav nquag siv los ua txheej txheej thaiv ua ntej Zinc los txhim kho cov txheej txheem ua haujlwm.Nws siv cov oxides ntawm titanium, chromium, thiab npib tsib xee.

Tam sim no cia peb tham me ntsis ntxiv txog cov hlau txheej ntawm cov hlau vim tias feem ntau cov qauv niaj hnub no tau tsim los ntawm cov hlau, thiab txhua yam kev lag luam sib txawv siv cov khoom tsim thiab cov khoom siv hlau.

Hard Steel Txheej

Lub hom phiaj tseem ceeb ntawm cov txheej tawv tawv rau cov hlau yog txhawm rau txhim kho nws cov kev tiv thaiv corrosion thiab lub zog hauv cov zawv zawg mechanism kom nws tuaj yeem tiv taus qhov hnyav tshaj plaws yam tsis muaj kev puas tsuaj.

Parts nrog hard steel txheej

Ntau lub tshuab, suav nrog hydraulics, nqa, thiab hydrophilic, nyob ntawm qhov nruam zawv zawg ntawm qhov chaw;Yog hais tias cov txheej yog tev tawm, qhov chaw poob lawv lub peev xwm los tiv thaiv corrosion, uas ua rau lub tshuab ua tsis tiav.Yog li ntawd, cov txheej txheem muaj zog tuaj yeem tiv taus kev txhuam thiab swb yam tsis muaj txheej txheej txheej txheej.

Qhov zoo

·   Siv cov txheej txheem hlau tiv thaiv rau saum npoo tiv thaiv cov khoom los ntawm kev puas tsuaj thiab hnav.

·   Tom qab siv cov txheej txheem hlau, nws yuav tiv taus hnav thiab tsim kua muag, ua rau qhov kawg-cov khoom siv tau ntev dua.

·   Cov txheej ntxiv kuj tseem pab nrog cov khoom siv substrate cov yam ntxwv ntawm lub cev thiab lub cev, xws li hardness thiab lub zog.

·   Koj puas tau hnov ​​lo lus"hlau huv si"?Nws alludes mus rau qhov chaw huv si rau lub sij hawm ntev.Nto nrog Metallic txheej tiv thaiv cov plua plav tsim hauv nws thiab tswj kev nyiam huv.

·   Tom qab nws yog xim hlau txheej, lub substrate nto yuav tshwm ci ntsa iab thiab txaus siab, ua rau nws yooj yim rau siv cov xim thaum lub sij hawm tom qab ua.
