Daim ntawv thov ntawm Polycarboxylic Superplasticizer

Nrog rau acceleration ntawm lub ntiaj teb no urbanization thiab kev xav tau ntau ntxiv rau kev tsim kho vaj tse, qhov kev thov rau cov khoom siv ua haujlwm siab hauv kev tsim kho kev lag luam yog loj hlob.Polycarboxylate superplasticizer (PCE), raws li niaj hnub kev sib xyaw ua vaj tse, ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov pob zeb ua kom muaj zog, ua haujlwm tau zoo, thiab ua haujlwm ntev vim nws cov dej txo qis thiab cov khoom tawg. Daim ntawv thov ntawmPCETsis tsuas yog txo cov dej-cement piv hauv cov pob zeb, tab sis kuj txo qis kev siv cov cement, yog li txo cov pa roj carbon dioxide emissions thaum lub sij hawm tsim kho, ua raws li kev txhim kho thoob ntiaj teb.

Raws li cov2024 Ntiaj teb Resources Outlookdaim ntawv tshaj tawm, kev lag luam tsim kho thoob ntiaj teb ntsib ob qho kev sib tw ntawm kev siv peev txheej thiab kev cuam tshuam ib puag ncig. Kev tsim kho kev lag luam yog cov neeg siv khoom loj ntawm cov peev txheej ntuj thiab qhov tseem ceeb ntawm cov pa hluav taws xob hauv tsev cog khoom. Yog li ntawd, kev ua tiav kev siv cov khoom siv hauv tsev thiab kev txhim kho kom ruaj khov yog qhov teeb meem ceev. Hauv cov ntsiab lus no, lub luag haujlwm ntawmPCEtseem ceeb heev. Los ntawm kev txo qis cov ntsiab lus cement hauv pob zeb,PCETsis tsuas yog txo cov nqi tsim khoom tab sis kuj txo qis cov pa roj carbon dioxide, pab kev tsim kho kev lag luam kom ua tiav kev hloov pauv ntsuab.

Nyob rau hauv xyoo tas los no, qhov kev thov rauPCEtau nce sai heev. Cov ntaub ntawv qhia tias covPCEkev ua lag luam yuav tsum tswj hwm qhov kev loj hlob txhua xyoo ntawm ntau dua 10% hauv xyoo tom ntej. Qhov kev loj hlob no feem ntau yog tsav los ntawm kev siv dav dav ntawm cov phiaj xwm loj loj thiab cov pob zeb ua haujlwm siab thoob ntiaj teb. Piv txwv li, Tuam Tshoj tus "14th Tsib-xyoo Plan rau Lub Tsev Zog Efficiency thiab Green Building Development" qhia meej meej los txhawb kev siv cov khoom siv ntsuab ntsuab ua tau zoo, muab txoj cai txhawb nqa rau kev txhim kho lub tsev.PCEkev lag luam. Ib txhij, ntau lawm technology ntawmPCEyog tsis tu ncua innovating. Los ntawm kev txhim kho polymerization technology thiab optimizing molecular qauv, cov tsimPCEnthuav tawm ntau ruaj khov thiab ua haujlwm tau zoo. Cov thev naus laus zis tshiab no tsis yog txhim kho cov dej-txo cov nyhuv ntawmPCEtab sis kuj txhim kho nws txoj kev yoog raws thiab kev ruaj ntseg hauv qhov chaw sib txawv.

Ntiaj teb no kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov txoj cai muab kev cia siab dav rau kev sivPCE. Ntxiv nrog rau Tuam Tshoj txoj kev txhawb nqa, cov qauv vaj tsev ntsuab zoo sib xws tau raug txhawb nqa hauv Tebchaws Europe thiab North America, hais txog kev txo qis cov pa roj carbon hneev taw ntawm cov khoom siv hauv tsev thiab txhim kho kev siv peev txheej. Piv txwv li, EU's Green Building Action Plan txhawb kev siv cov khoom siv hauv tsev uas muaj cov pa roj carbon tsawg tsawg, txhawb kev txhim kho ntxiv.PCEkev ua lag luam.

Kev sib tw thiab kev cia siab

Txawm tias qhov tseem ceeb zoo ntawmPCE, nws txoj kev txhim kho kev lag luam ntsib qee qhov kev sib tw. Piv txwv li, kev hloov pauv ntawm tus nqi raw khoom yuav cuam tshuam rau tus nqi tsim khoom thiab tus nqi lag luam ntawmPCE. Tsis tas li ntawd, ua kom muaj kev ua haujlwm siabPCExav tau cov txheej txheem sib xyaw ua ke thiab kev tswj xyuas nruj, ua kom muaj kev xav tau ntau dua rau cov tuam txhab tsim khoom. Txawm li cas los xij, los ntawm kev nruam kev thev naus laus zis thiab kev lag luam nthuav dav, lubPCEkev lag luam tau cia siab tias yuav ua tiav kev txhim kho ntau dua yav tom ntej. Tshwj xeeb nrog kev nrov ntawm lub tsev ntsuab lub tswv yim thiab kev nce qib ntawm kev tiv thaiv ib puag ncig, kev ua lag luam ze rauPCEyuav ua kom dav.

Xaus

Polycarboxylate superplasticizer, raws li ib qho tseem ceeb admixture nyob rau hauv niaj hnub kev tsim kho engineering, yog ua ib tug tseem ceeb kev koom tes rau lub sustainable kev loj hlob ntawm kev tsim kho kev lag luam vim nws cov kev ua tau zoo heev thiab dav daim ntawv thov. Nyob rau hauv lub ntsej muag ntawm nce thoob ntiaj teb cov peev txheej thiab ib puag ncig kev nyuaj siab, lubPCEkev lag luam tau npaj rau txoj kev loj hlob dav dav los ntawm kev tsim kho thev naus laus zis thiab kev txhawb nqa txoj cai, muab kev txhawb zog rau kev ua tiav cov vaj tsev ntsuab, cov pa roj carbon tsawg.
