Cov yeeb nkab steeldescaling yog hais txog kev tshem tawm ntawm xeb, oxidized ntawm daim tawv nqaij, av, thiab lwm yam nyob rau saum npoo ntawm cov yeeb nkab steel los kho cov xim hlau ntawm cov yeeb nkab steel los xyuas kom meej qhov adhesion thiab cov nyhuv ntawm cov txheej tom ntej los yog kev kho corrosion. Descaling tuaj yeem tsis tsuas yog txuas lub neej kev pab cuam ntawm cov yeeb nkab steel, tab sis kuj txhim kho nws cov tsos thiab corrosion kuj.
Lub luag haujlwm ntawm descaling steel yeeb nkab
1. Txhim khu cov nyhuv anti-corrosion: Los ntawm kev tshem tawm xeb, adhesion ntawm anti-corrosion txheej tuaj yeem nce ntxiv, ua rau cov yeeb nkab steel ntau dua corrosion-resistant.
2. Kev pab cuam lub neej ntev: tshem tawm cov tawv nqaij oxidized thiab xeb txheej ntawm cov yeeb nkab steel tuaj yeem pab kom ntev kev pab cuam lub neej ntawm cov yeeb nkab steel.
3. Txhim kho qhov tsos: qhov saum npoo ntawm cov yeeb nkab steel tom qab descaling yog ntau du thiab zoo nkauj, nyob rau hauv txoj kab nrog cov kev xav tau ntawm qhov project tsim.
4. Yooj yim rau kev ua haujlwm tom ntej: tom qab descaling, nws yog qhov yooj yim rau kev tsim kho txheej thiab anticorrosion txheej los txhim kho kev tsim kho kom zoo thiab zoo.
Cov txheej txheem ntawm descaling steel yeeb nkab
1. Phau ntawv descaling
Siv hlau txhuam, ntawv xuab zeb, scrapers thiab lwm yam cuab yeej siv los tshem tawm xeb.
Qhov zoo: tus nqi qis, tsim nyog rau thaj chaw me me lossis kaum qhov chaw.
Disadvantages: tsawg efficiency, tsis sib npaug descaling nyhuv, tsis haum rau loj cheeb tsam descaling.
2. Mechanical xeb tshem tawm
Siv cov cuab yeej hluav taws xob lossis pneumatic, xws li sanders thiab grinders kom tshem tawm xeb.
Qhov zoo: kev ua haujlwm siab dua li phau ntawv descaling, haum rau nruab nrab qhov chaw descaling.
Qhov tsis zoo: nws yog qhov nyuaj rau kev ua tiav cov txheej txheem siab ntawm kev kho deg, thiab cov nyhuv cuam tshuam los ntawm cov cuab yeej.
3. Sandblasting xeb tshem tawm (los yog tua blasting xeb tshem tawm)
Kev siv cov cua compressed yuav yog abrasive (xws li xuab zeb, steel tua) high-speed dav hlau mus rau saum npoo ntawm cov yeeb nkab steel kom tshem tawm cov xeb txheej.
Qhov zoo: kev ua haujlwm siab, zoo xeb tshem tawm zoo, tuaj yeem ua tiav qib siab ntawm kev huv.
Qhov tsis zoo: cov khoom siv kim, cov txheej txheem tsim cov plua plav thiab suab nrov, haum rau kev ua haujlwm sab nraum zoov lossis thaj chaw loj.
4. Tshuaj tshem tawm xeb
Siv cov txheej txheem tshuaj xws li pickling kom tshem tawm cov xeb txheej los ntawm acidic tov.
Qhov zoo: haum rau cov duab ntawm cov yeeb nkab steel, tuaj yeem tshem tawm cov txheej txheej tuab.
Disadvantages: corrosive, yuav tsum tau neutralized, unfriendly rau ib puag ncig, siab kho nqi.
5. High-pressure dej dav hlau descaling
Siv dav hlau dej siab los cuam tshuam rau saum npoo ntawm cov yeeb nkab steel kom tshem tawm xeb txheej, av thiab txheej txheej qub.
Qhov zoo: tsis muaj plua plav, kev tiv thaiv ib puag ncig, haum rau cov txheej txheem xeb tuab.
Disadvantages: Tom qab tshem tawm xeb, qhov saum npoo yog ntub thiab yuav tsum tau qhuav tam sim ntawd.
6. Laser xeb tshem tawm
Siv high-zog laser beam ua nyob rau saum npoo ntawm cov yeeb nkab steel kom vaporize lub xeb txheej.
Qhov zoo: kev tiv thaiv ib puag ncig, siab precision, haum rau cov xwm txheej xav tau.
Disadvantages: khoom kim heev, haum rau cov kev xav tau tshwj xeeb.
Kev kho mob tom qab xeb tshem tawm
Tom qab ua tiav ntawm cov yeeb nkab steel descaling, qhov saum npoo yog feem ntau raug rau huab cua thiab yooj yim rov oxidized, yog li nws yog feem ntau yuav tsum tau ua raws li kev kho mob tam sim ntawd:
1. Siv cov tshuaj tiv thaiv corrosion: Siv cov tshuaj tiv thaiv corrosion los yog pleev xim rau ntawm qhov chaw ntawm cov yeeb nkab steel kom tsis txhob rov xeb.
2. Kub-dip galvanizing: Txhim kho corrosion kuj ntawm steel yeeb nkab los ntawm galvanizing, haum rau kev siv ntev ntawm cov yeeb nkab steel.
3. Kev kho mob Passivation: Kev kho Passivation yog ua los ua kom oxidation tsis kam.
4. Phosphating kev kho mob: Pab kom cov adhesion ntawm txheej thiab muab kev tiv thaiv corrosion ntxiv.
Cov cheeb tsam thov
1. Kev tsim kho: siv rau kev tsim vaj tsev,scaffolding, thiab lwm yam kom nce kev pab cuam lub neej.
2. Petrochemical engineering: siv rau descaling ntawm kev thauj mus los pipelines thiab khoom siv los txhim kho corrosion kuj.
3. kev kho dej engineering: siv rau cov kav dej thiab cov kav dej phwj kom tsis txhob muaj corrosion.
4. Marine kev lag luam: tiv thaiv xeb thiab descaling kho rau nkoj hulls thiab marine pipelines.
5. Cov chaw tsheb thauj mus los: xws li txuas hniav, cov chaw zov me nyuam thiab lwm qhov chaw kom tshem tawm xeb thiab tiv thaiv corrosion.
