Nyob rau hauv cov txheej txheem ntawm kev tsim cov cement pipelines, dej txo tus neeg sawv cev, ua ib qho tseem ceeb additive, plays lub luag hauj lwm indispensable. Cov dej-txo cov neeg ua haujlwm tuaj yeem txhim kho kev ua haujlwm ntawm cov pob zeb ua haujlwm, txhim kho kev tsim kho kom zoo, thiab ua kom qhov project zoo. Cement yeeb nkab chaw tsim tshuaj paus Zhangda Cement Cov Khoom lag luam yuav sib tham txog kev siv cov dej txo cov neeg ua haujlwm thiab lawv cov txheej txheem ntawm kev nqis tes ua thaum siv cov yeeb nkab cement.
1. Txhim kho kev ua haujlwm ntawm pob zeb
Dej txo tus neeg sawv cev yog siv los ua cov khoom sib xyaw hauv cov cement pipeline tsim. Nws tuaj yeem txo cov dej siv ntawm cov pob zeb thaum tswj cov dej ntws ntawm cov pob zeb. Tus neeg saib xyuas dej txo qis qhov nro ntawm cov dej los ntawm dispersing cement particles, kom cov pob zeb tseem muaj peev xwm tuav tau zoo fluidity thiab scalability ntawm ib tug tsawg dej-cement ratio. Qhov no ua rau cov pob zeb yooj yim dua rau ncuav, vibrate thiab compact, txo jamming thiab cais thaum tsim kho.
2. Txhim kho pob zeb ua kom muaj zog
Kev siv cov dej-txo cov neeg ua haujlwm tuaj yeem txo cov cement hauv pob zeb thiab txo cov dej-cement piv, yog li txhim kho lub zog compressive ntawm pob zeb. Dej txo tus neeg sawv cev tuaj yeem txhim kho lub zog sib txuas ntawm cov cement thiab aggregate, txo qhov shrinkage thiab txo qhov kev pheej hmoo ntawm pob zeb tawg. Yog li ntawd, kev siv cov dej txo cov neeg ua haujlwm pab txhim kho lub zog compressive thiab durability ntawm cov kav dej cement.
3. Txhim kho kev ua haujlwm tiv thaiv permeability
Cov dej-txo cov neeg ua haujlwm tuaj yeem txhim kho cov qauv pore hauv pob zeb thiab ua kom nws denser, yog li txhim kho cov impermeability ntawm pob zeb. Kev txhim kho ntawm impermeability tuaj yeem pab txuas ntxiv lub neej kev pab cuam ntawm cov cement pipelines thiab txo qhov tshwm sim ntawm to thiab corrosion.
4. Txhim kho kev tsim kho kom zoo
Hauv kev tsim cov kav dej cement, kev siv cov dej txo cov neeg ua haujlwm tuaj yeem txhim kho kev tsim kho kom zoo. Vim tias cov dej txo cov neeg ua haujlwm tuaj yeem txhim kho kev ua haujlwm ntawm cov pob zeb ua haujlwm, ua rau cov dej ntws, vibrating thiab lwm yam kev tsim kho sai thiab ua haujlwm zoo dua. Nyob rau tib lub sijhawm, cov neeg ua dej txo qis tuaj yeem txo qhov kev teeb tsa thawj zaug thiab lub sijhawm kawg ntawm kev ua vaj tse, ua kom cov kev tsim kho kom zoo, thiab txo cov nqi tsim kho.
5. Txo cov nqi kho cov kav dej cement
Kev siv cov dej txo cov neeg ua haujlwm pab txhim kho qhov zoo thiab kav ntev ntawm cov kav dej cement, yog li txo cov nqi tu cov kav dej thaum siv. Vim hais tias cov dej-txo tus neeg sawv cev tuaj yeem txhim kho lub zog thiab impermeability ntawm pob zeb, nws txo cov teeb meem los ntawm kev xau thiab corrosion, thiab txo qhov zaus ntawm kev kho thiab hloov. Qhov no tsis tsuas yog txuag cov nqi txij nkawm, tab sis kuj ua kom muaj kev ua haujlwm zoo ntawm lub nroog.
Hauv cov ntsiab lus, cov dej txo cov neeg ua haujlwm ua lub luag haujlwm tseem ceeb hauv kev tsim kho cov kav dej cement. Los ntawm kev txhim kho kev ua haujlwm ntawm cov pob zeb, ua kom muaj zog thiab impermeability, txhim kho kev tsim kho, thiab txo cov nqi kho, cov neeg ua dej txo qis muab kev txhawb zog rau kev tsim cov kav dej cement. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, daim ntawv thov ntawm cov dej txo cov neeg ua haujlwm yuav txuas ntxiv txhim kho thiab txhim kho, muab kev txhawb nqa kev txhim khu kev qha rau yav tom ntej engineering. Yog li ntawd, kev siv cov dej-txo cov neeg ua haujlwm kom muaj nuj nqis thaum lub sij hawm tsim kho cov kav dej cement muaj qhov tseem ceeb ntawm kev siv thiab kev txhawb nqa tus nqi.
