Dab tsi yog qhov muaj pes tsawg leeg thiab cov qauv ntawm cov pob zeb accelerator?
Apr 07, 2024
Accelerators yog ib hom kev tsim cov khoom siv ntxiv, siv los txhawb qhov kev teeb tsa thaum ntxov ntawm cov pob zeb, txhim kho lub zog thiab hardness ntawm pob zeb, thiab txo cov sij hawm teeb tsa ntawm pob zeb. Accelerators muab kev yooj yim, kev ua tau zoo, thiab cov txiaj ntsig ib puag ncig, yog li tau siv dav hauv ntau yam kev tsim vaj tsev, xws li txuas hniav, tunnels, thiab hydraulic engineering tej yaam num.
Accelerators muaj ntau yam khoom, feem ntau suav nrog silicates, calcium carbonate, calcium hydroxide, aluminates, thiab sulfates. Ntawm cov no, silicates yog cov khoom tseem ceeb ntawm cov accelerators, muaj peev xwm txhim kho cov dej noo thiab compactness ntawm cov pob zeb, txhawb kev teeb tsa thaum ntxov ntawm cov pob zeb kom tau txais lub zog zoo thiab hardness hauv lub sijhawm luv luv. Calcium carbonate tuaj yeem maj mam tso cov pa roj carbon dioxide, txhawb nqa cov tshuaj tiv thaiv hardening ntawm pob zeb, ua kom nws qhov ntom thiab tawv. Calcium hydroxide tuaj yeem nce PH tus nqi ntawm pob zeb, txhawb nws qhov teeb meem tshwm sim. Aluminates tuaj yeem ua rau kom cov pob zeb compactness, txhim kho nws lub zog thiab hardness. Sulfates tuaj yeem txhawb nqa cov tshuaj tiv thaiv tawv tawv ntawm cov pob zeb, tab sis cov ntsiab lus ntau dhau tuaj yeem ua rau muaj kev cuam tshuam rau kev ua haujlwm ntawm pob zeb.
Raws li kev xav tau ntawm kev tsim vaj tsev sib txawv, qhov sib xyaw thiab kev tsim cov accelerators kuj sib txawv. Feem ntau, kev tsim cov accelerators yuav tsum xav txog cov hauv qab no: ua ntej, pob zeb muaj zog thiab hardness yuav tsum tau; thib ob, kev teeb tsa lub sijhawm; thib peb, pob zeb cement thiab aggregate hom; plaub, pob zeb kub thiab av noo; thib tsib, hom thiab cov khoom ntawm accelerators. Nyob rau hauv qhov tseeb kev npaj ntawm accelerators, cov kev ntsuam xyuas yuav tsum tau ua ua ntej los txiav txim qhov zoo tshaj plaws Cheebtsam thiab formulations los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm pob zeb.
Raws li ib hom kev tsim kho cov khoom siv ntxiv, cov accelerators tuaj yeem txhim kho cov pob zeb ua kom muaj zog thiab tawv, thiab ua kom lub sijhawm ua vaj tse, txhim kho kev tsim kho thiab txo cov nqi tsim kho. Qhov yooj thiab ib puag ncig tus phooj ywg ntawm accelerators kuj ua rau lawv yog ib qho tseem ceeb hauv kev tsim kho engineering. Nrog kev txhim kho thev naus laus zis tsis tu ncua, cov qauv tsim thiab cov khoom siv ntawm cov accelerators yuav txuas ntxiv txhim kho thiab txhim kho, txhaj tshuaj tshiab tseem ceeb thiab lub zog rau hauv kev tsim kho kev lag luam.
