Pickling Steel Tubes siv ntau lub tank thiab ib lub tank txoj kev

Nyob rau hauv ntau lub tank txoj kev ntawm pickling steel hlab, cov hlab yog thawj pre-pickled nyob rau hauv lub tank nrog ib tug kuj tsis tshua muaj acid concentration tab sis siab hlau ntsev ntsiab lus. Nyob rau theem no, qhov kub ntawm cov kua qaub tuaj yeem nce siab dua, muab ntau yam txiaj ntsig. Ua ntej, nws pab tshem tawm cov kab mob me me thiab lwm yam impurities nyob rau saum npoo ntawm cov hlab steel. Thib ob, nyob rau hauv high-temperature acid pickling tov, lub dissolution tus nqi ntawm tuab zeb nplai accelerates, yooj yim rau diffusion ntawm hydrogen atoms rau hauv cov hlau substrate thiab tom qab tsim hydrogen gas. Raws li cov roj hydrogen khiav tawm, nws ua rau cov nplai zeb tev tawm. Thirdly, txij li thaum muaj ntau ntawm zeb nplai thiab lwm yam av tau khaws cia rau hauv lub tank ua ntej pickling, qhov no ua kom huv si ntawm cov tshuaj pickling hauv qhov kawg pickling tank.
