Painting & Txheej
Kev kho deg ntawm cov yeeb nkab steel: txhawm rau txhim kho lub neej kev pab cuam ntawm cov kav dej, kev kho deg feem ntau yog ua los pab txhawb kev sib xyaw ua ke ntawm cov yeeb nkab steel thiab cov txheej txheem tiv thaiv corrosion.Cov txheej txheem ua haujlwm feem ntau yog: tu, cuab yeej derusting, pickling, tua blasting derusting. plaub pawg.
1.Tshuaj Roj, plua plav, roj nplua nyeem, organic teeb meem adhered rau saum npoo ntawm cov yeeb nkab steel, feem ntau yog siv cov kuab tshuaj, emulsion los ntxuav qhov chaw.Txawm li cas los xij, cov xeb, oxide daim tawv nqaij thiab vuam slag ntawm cov yeeb nkab steel tsis tuaj yeem raug tshem tawm, yog li lwm txoj kev kho mob yuav tsum tau.Tool xeb tshem tawm steel yeeb nkab nto oxide, xeb, vuam slag, tuaj yeem siv steel hlau txhuam los ntxuav thiab txhuam qhov chaw kho.
2.Tool derusting tuaj yeem muab faib ua phau ntawv thiab lub zog, phau ntawv cuab yeej derusting tuaj yeem ncav cuag Sa 2 qib, lub cuab yeej hluav taws xob derusting tuaj yeem ncav cuag Sa3 qib. cov xeb nrog kev pab ntawm cov cuab yeej, yog li peb yuav tsum nrhiav lwm txoj hauv kev.
3.Pickling Common pickling txoj kev muaj xws li chemistry thiab electrolysis.Tab sis tsuas yog cov tshuaj pickling yog siv rau pipeline corrosion tiv thaiv.Chemical pickling yuav ua tau ib tug tej yam kev huv si thiab roughness nyob rau saum npoo ntawm cov yeeb nkab steel, uas yog yooj yim rau tom ntej thauj tog rau nkoj kab. txhaj tshuaj (xuab zeb) tom qab reprocessing.
4.Shot blasting rau xeb tshem tawm.By siab zog lub cev muaj zog tsav lub high-speed rotating hniav, steel grit, steel txhaj, ntu, minerals thiab lwm yam abrasive hlau nyob rau hauv qhov kev txiav txim ntawm centrifugal quab yuam ntawm steel yeeb nkab nto tshuaj tsuag thiab loj ejection, kom huv si tshem tawm. xeb, oxides thiab av ntawm ib sab tes, ntawm qhov tod tes, cov yeeb nkab steel nyob rau hauv qhov kev txiav txim ntawm abrasive hnyav cuam tshuam thiab kev sib txhuam quab yuam, kom ua tiav qhov yuav tsum tau ua kom zoo li qub. cev derust.Feem ntau, txhaj tshuaj blasting thiab derusting yog tsuas yog siv rau sab hauv kev kho mob ntawm cov yeeb nkab steel, thiab tua blasting thiab derusting yog tsuas yog siv rau sab nrauv kho cov yeeb nkab steel.
