Kev lag luam kev lag luam thiab kev ua haujlwm kho dua tshiab ntawm cov pob zeb txhawb kev loj hlob ntawm cov khoom sib xyaw
Sib txawv ntawm qhov kev xav tau ruaj khov nkhaus ntawm kev lag luam cement, cov khoom siv sib xyaw muaj qee qhov kev loj hlob zoo, nrog rau qhov sib txawv ntawm qhov kev xav tau ntawm tag nrho downstream thiab chav noj. Admixtures feem ntau yog siv rau hauv cov pob zeb sib xyaw ua ke, thiab kev lag luam nce ntxiv ntawm cov pob zeb ua rau muaj kev nce ntxiv hauv tag nrho cov kev thov rau cov khoom sib xyaw. Txij li xyoo 2014, kev tsim cov cement tau ruaj khov, tab sis kev tsim cov pob zeb ua lag luam tau nce xyoo los ntawm xyoo, nrog kev loj hlob txhua xyoo ntawm 12% hauv tsib xyoos dhau los. Tau txais txiaj ntsig los ntawm kev txhawb nqa txoj cai, ntau thiab ntau qhov kev xav tau tiag tiag yog siv cov khoom lag luam npaj sib xyaw ua ke. Centralized zus tau tej cov pob zeb ua lag luam thiab kev thauj mus los rau qhov project site siv cov tsheb thauj khoom sib tov yog qhov zoo rau kev ua tiav cov kev tswj xyuas kom zoo, ntau cov khoom siv scientific proportioning, yooj yim dua pouring kev tsim kho, thiab zoo txo cov pa phem ib puag ncig los ntawm cov cement hauv kev tsim kho.
Cov khoom lag luam hloov pauv hloov tshiab muab kev loj hlob zoo heev rau cov khoom tshiab
Cov dej txo cov neeg ua haujlwm lawv tus kheej muaj peev xwm loj hlob zoo, feem ntau yog vim muaj kev hloov pauv dav dav coj los ntawm kev hloov tshiab tiam tshiab. Qhov thib peb tiam dej txo tus neeg saib xyuas, tseem hu ua kev ua haujlwm siab dej txo tus neeg sawv cev, nrog polycarboxylic acid ua cov khoom tseem ceeb, tau maj mam dhau los ua lub hauv paus ntawm kev ua lag luam. Nws cov dej txo tus nqi tuaj yeem ncav cuag ntau dua 25%, thiab nws txoj kev ywj pheej molecular yog qhov loj, nrog rau qib kev hloov kho siab thiab cov dej ntws zoo txhawb kev ua haujlwm. Qhov no zoo heev txhim kho kev lag luam ua tau zoo ntawm lub zog siab thiab ultra-siab zog ua vaj tse, thiab yog li qhov kev faib ua feem yog nce xyoo los ntawm xyoo.
Cov qauv kev lag luam ntawm kev lag luam additive: customization thiab siab viscosity
Lub hom phiaj cov neeg siv khoom ntawm cov dej txo cov neeg ua haujlwm yog cov tuam txhab ua vaj tse. Feem ntau muaj ob hom ntawm pawg, ib qho yog cov chaw tsim khoom ua vaj tsev ua lag luam, uas nws qhov chaw ua lag luam raug kho, feem ntau yog tawg rau thaj tsam 50 km ntawm qhov chaw sib tov. Hom kev tsim cov neeg siv khoom no feem ntau yog nyob ib puag ncig hauv nroog, feem ntau yog kev pabcuam vaj tsev, nroog pej xeem vaj tse, hauv nroog engineering thiab lwm yam haujlwm. Qhov thib ob yog engineering cov neeg siv khoom, xws li cov neeg ua haujlwm tsim kho rau kev thauj mus los loj thiab
kev txuag dej thiab kev tsim hluav taws xob. Vim yog qhov sib txawv ntawm cov phiaj xwm kev tsim kho vaj tse los ntawm thaj chaw hauv nroog thiab kev xav tau tawg, cov tuam txhab tsim kho feem ntau tsim cov pob zeb sib xyaw ua ke lawv tus kheej tsis yog siv cov khoom lag luam uas twb muaj lawm hauv nroog.
