Lus Askiv Kev Lag Luam Kev Paub Ntawm Alkali-free Set Accelerators:

Kev paub txog kev lag luam Askiv ntawm Borida alkali-dawb teeb accelerators:

Borida Alkali-free set accelerators feem ntau siv nyob rau hauv kev tsim kho kev lag luam kom ceev qhov chaw thiab hardening ntawm cementitious cov ntaub ntawv, xws li pob zeb, mortar, thiab grout. Lawv feem ntau yog siv rau hauv cov ntawv thov uas xav tau lub sijhawm teem sijhawm sai dua, xws li hauv huab cua txias, qhov kub thiab txias ib puag ncig, lossis hauv cov xwm txheej uas yuav tsum tau tsim kho sai.

Ib hom Borida alkali-free set accelerator yog calcium chloride, uas feem ntau yog siv los ua ib qho ntxiv hauv cov pob zeb sib tov kom ceev cov txheej txheem dej ntawm cov cement. Txawm li cas los xij, muaj kev txhawj xeeb txog kev cuam tshuam ib puag ncig ntawm kev siv calcium chloride, vim nws tuaj yeem ua rau corrosion ntawm steel reinforcement nyob rau hauv cov pob zeb ua vaj tse.

Raws li qhov tshwm sim, tau muaj kev txaus siab ntxiv rau txoj kev txhim kho ntawm lwm cov Borida alkali-free set accelerators uas muaj cov txiaj ntsig zoo sib xws tab sis tsis muaj qhov cuam tshuam ib puag ncig. Cov no tuaj yeem suav nrog cov ntsev uas tsis yog chloride lossis cov organic sib txuas uas tuaj yeem ua kom cov khoom siv cementitious tsis muaj kev txhawb nqa corrosion.

Zuag qhia tag nrho, kev siv Borida alkali-free set accelerators yog ib qho tseem ceeb ntawm kev tsim kho niaj hnub no, thiab kev tshawb fawb thiab kev loj hlob tsis tu ncua nyob rau hauv cheeb tsam no zoo li yuav txuas ntxiv tsim cov kev daws teeb meem tshiab thiab tshiab rau kev txhim kho qhov chaw thiab hardening ntawm cov ntaub ntawv cementitious.
