Kev tsom xam ntawm cov ua rau muaj kev xeb hauv cov granulators yas

Thaum lub sijhawm ua haujlwm ntawm cov yas granulators, vim hais tias muaj kev cuam tshuam ntawm ib puag ncig lossis tshuaj lom neeg, qee cov khoom siv ntawm cov khoom siv tau puas. Qhov kev puas tsuaj no yog hu ua cov cuab yeej corrosion. Txoj kev corrosion tshwm sim ntawm cov granulators yog feem ntau yog manifested raws li: kab nrib pleb, pits, hnav thiab lwm yam tshwm sim hauv qee cov khoom siv. Lub hauv paus corrosion yog nyob rau hauv huab cua lossis dej, cov hlau nto undergoes tshuaj oxygen nrog cov electrolyte tov, yog li ua kom cov khoom siv hlau. Thaum lub sij hawm corrosion ntawm cov ntaub ntawv metallic, lawv maj mam plam lawv cov thawj lus piv thiab tawv ncauj, thiab tej zaum yuav ua rau cov khoom puas lossis ua haujlwm tsis ua haujlwm. Yog li, kev tiv thaiv thiab tswj cov qhov tshwm sim corrosion ntawm yas granulators yog qhov tseem ceeb rau kev ncua lub neej ntawm cov khoom siv thiab ua kom muaj kev txhim kho ntau dua. Cov hauv qab no yog kev tsom xam ntawm cov laj thawj ntawm cov huab cua yas: 1. Cov tshuaj corrosion no feem ntau yog ua rau muaj kev tsim cov xeb, cov roj av hauv av hauv cov dej sib tw Qhov kev corrosion no feem ntau yog ua kom pom raws li cov pits, tawg los yog xeb ntawm cov hlau nto. Chloride ions, sulfates thiab lwm cov tshuaj electrolytes yog siv nyob rau hauv ib puag ncig cov tshuaj lom neeg uas ua rau cov tshuaj lom neeg nrog cov hlau nto, ua rau cov hlau corrosion. Qhov kev corrosion no feem ntau yog ua rau kev yaig lossis kev sib cais ntawm cov hlau. Cov ntsiab lus tseem ceeb ntawm cov tshuaj corrosion xws li acids, alkalis thiab ntsev rau hauv kev sib cuag nrog cov tshuaj electrolyte thiab muaj qhov muaj peev xwm sib txawv. Qhov kev corrosion no feem ntau yog ua rau muaj kev corrosion hauv zos lossis pitting ntawm cov hlau. Electrochemical corrosion yog ib qho txheej txheem corrosion tshwm sim los ntawm kev ntws ntawm cov hluav taws xob ntawm cov hlau ntawm cov hlau.
