Kev rhuav tshem thiab tshem tawm cov nplai ntawm cov bolts muaj zog heev

Cov txheej txheem ntawm kev tshem tawm cov hlau oxide phaj ntawm cov hlau hlau txias yog stripping thiab descaling. Muaj ob txoj kev: mechanical descaling thiab tshuaj pickling. Hloov cov txheej txheem tshuaj pickling ntawm cov hlau hlau nrog mechanical descaling txhim kho kev tsim khoom thiab txo cov pa phem ib puag ncig. Cov txheej txheem descaling no suav nrog txoj kev khoov, txoj kev txau, thiab lwm yam. Cov nyhuv descaling zoo, tab sis cov hlau seem tsis tuaj yeem tshem tawm. Tshwj xeeb tshaj yog thaum qhov ntsuas ntawm cov hlau oxide nplai muaj zog heev, yog li qhov mechanical descaling cuam tshuam los ntawm qhov tuab ntawm cov hlau nplai, cov qauv thiab lub xeev kev ntxhov siab, thiab yog siv rau hauv cov hlau hlau carbon rau cov khoom siv tsis muaj zog. Tom qab mechanical descaling, cov hlau hlau rau cov khoom siv muaj zog siab dhau los ntawm cov txheej txheem tshuaj pickling kom tshem tawm tag nrho cov hlau oxide nplai, uas yog, compound descaling. Rau cov hlau hlau carbon qis, cov hlau ntawv tshuav los ntawm mechanical descaling yuav ua rau tsis sib xws hnav ntawm cov qauv nplej. Thaum lub qhov qauv nplej lo rau cov hlau ntawv vim yog kev sib txhuam ntawm cov hlau hlau thiab qhov kub sab nraud, qhov chaw ntawm cov hlau hlau tsim cov cim nplej ntev.
