Descaling txoj kev thiab muab qhab nia ntawm steel qauv - Xov xwm - Qingdao Eihe Steel Structure Group Co., Ltd.

Descaling txoj kev thiab grading ntawm steel lug

Cov hlau loj yog xav tau nyob rau hauv kev tsim cov qauv steel, tab sis yog tias cov hlau siv hauv kev tsim rusts ntau, nws yuav ua rau lub neej ua haujlwm luv. Rau kev nyab xeeb ntawm tus kheej kuj yog ib qho kev sib tw, lub cev qhuav dej ntawm lub tsev yog qhov tshwm sim, nyob rau hauv xyoo tas los no ntau thiab ntau xim, hnub no Fangtong steel qauv yuav qhia koj qee txoj kev tshem tawm xeb!

1. Descaling los ntawm pickling

Nws yog yuav tsum tau muab cov tswv cuab hlau los pleev xim rau hauv lub pas dej ua kua qaub, thiab tshem tawm cov roj thiab xeb ntawm cov tswv cuab nrog cov kua qaub. Kev ua haujlwm ntawm cov txheej txheem pickling kuj yog siab, thiab kev tshem tawm xeb yog ntau dua, tab sis tom qab pickling, cov khoom yuav tsum tau muab yaug nrog dej kub lossis dej, thiab yog tias muaj cov kua qaub seem, qhov corrosion ntawm cov khoom yuav muaj zog dua.

2 、 Descale manually

Nws yog tshem tawm cov xeb ntawm cov khoom hlau los ntawm kev siv tes ua haujlwm nrog qee cov cuab yeej yooj yim, xws li scraper, sib tsoo log, emery daim ntaub, hlau txhuam thiab lwm yam cuab yeej. Txoj kev no muaj kev ua haujlwm tsawg, kev ua haujlwm tsis zoo thiab kev tshem tawm tsis tiav.

3, Sandblast thiab descale

Nws yog kev siv cov cua compressed, nruam quartz xuab zeb lossis hlau xuab zeb cuam tshuam rau saum npoo ntawm cov khoom siv hlau, qhov chaw ntawm cov hlau xeb, roj thiab lwm cov khib nyiab ntxuav, nthuav tawm cov hlau hlau xim ntawm txoj kev tshem tawm xeb. Txoj kev no muaj kev ua haujlwm siab, tshem tawm xeb kom huv si, thiab yog txheej txheem kev tshem tawm xeb ntau dua.

Yuav ua li cas cais cov qauv hlau xeb qib?

Qib A: Cov hlau nplaum uas tau npog tag nrho nrog cov tawv nqaij oxidized thiab yuav luag tsis muaj xeb.
Qib B: Hlau nto uas tau xeb thiab ib feem ntawm daim tawv nqaij oxide tau tev tawm.
Qib C: daim tawv nqaij oxide tau raug tev tawm vim yog xeb lossis tuaj yeem raug khawb tawm, thiab me me ntawm pitting ntawm steel nto
Qib D: Hlau qhov chaw uas cov tawv nqaij oxide tau raug tshem tawm tag nrho vim yog corrosion thiab generalized pitting tau tshwm sim.
