Chloride ion yog ib qho teeb meem hauv cov cement thiab cement raw cov ntaub ntawv.Nws muaj kev cuam tshuam ncaj qha rau preheater thiab kiln calcination hauv cov txheej txheem qhuav cement tshiab, ua rau muaj kev sib tsoo xws li lub nplhaib tsim thiab ntsaws, cuam tshuam rau cov khoom siv ua haujlwm thiab cov cement clinker zoo.Tam sim no, thaum cov ntsiab lus chloride ion hauv cov cement ntau tshaj ib. Tej yam nqi, nws yuav corrode steel bar hauv pob zeb, txo lub zog ntawm steel bar, kuj tuaj yeem ua rau pob zeb puas tsuaj los ntawm kev nthuav dav, thiab thaum loj heev, nws yuav ua rau pob zeb tawg thiab faus zais qhov phom sij rau qhov zoo ntawm qhov project, yog li nws yuav tsum tau nruj me ntsis tswj.Qhov yuav tsum tau rau chloride ion txwv yog ntxiv nyob rau hauv tsab xov xwm 7.1 ntawm GB 175-2007 Common portland cement.
Qhov yuav tsum tau muaj cov ntsiab lus chloride hauv cov cement tsis ntau dua 0.06%.Txawm li cas los xij, vim tias qhov ruaj khov ntawm cov nyiaj chloride tsis zoo, cov qauv ntawm cov nyiaj (chlorine) electrode tsis ruaj khov, thiab kev cuam tshuam ib puag ncig zoo dua, lawv ua rau tsis zoo rov ua dua thiab tsim nyog rau kev tshawb nrhiav cov tshuaj uas muaj cov ntsiab lus chloride siab.Ion chromatography, raws li txoj kev nyiam rau kev tshawb nrhiav cov tshuaj ionic, tuaj yeem siv los txheeb xyuas ntau yam ions ib txhij nrog ib qho kev txhaj tshuaj, thiab muaj cov yam ntxwv ntawm kev ceev thiab raug.
Nyob rau hauv daim ntawv no, ion chromatography yog siv los soj ntsuam thiab kuaj pob zeb additives thiab chloride ion nyob rau hauv cov cement.
