FC-651S Cov Khoom Kub Kub Kub Kub Loss Control Additives
• FC-651S muaj ntau yam zoo thiab tuaj yeem siv rau hauv ntau hom cement slurry systems.Nws muaj zoo compatibility nrog lwm yam additives.Raws li FC-650S, cov khoom tau txhim kho nws cov ntsev tiv thaiv thiab muaj cov ntsev ua haujlwm zoo dua.
• FC-651S yog qhov tsim nyog rau qhov kub thiab txias nrog kev kub siab txog li 230 ℃.Qhov kev ncua kev ruaj ntseg ntawm cov cement slurry system nyob rau hauv high-temperature ib puag ncig yog zoo dua vim yog qhia HA .
• FC-651S tuaj yeem siv ib leeg.Cov nyhuv zoo dua thaum siv ua ke nrog FC-631S / FC-632S.
• Nws yog tsim rau dej tshiab / dej ntsev slurry npaj.
Cov roj av kub kub ntsib ib qho teeb meem tshwj xeeb thaum nws los txog rau kev ua kom zoo.Ib qho ntawm cov teeb meem no yog qhov teeb meem ntawm cov kua dej poob, uas tuaj yeem tshwm sim thaum cov av nkos filtrate invades qhov tsim thiab ua rau txo cov kua ntim.Yuav kom daws tau qhov teeb meem no, peb tau tsim ib qho tshwj xeeb cov kua dej poob reducer uas yog tsim tshwj xeeb rau siv nyob rau hauv high-temperature roj teb.FC-651S yog qhov kub thiab txias ua kom tsis muaj kuab tshuaj ntxiv thiab nws tsim nyog rau kev lag luam Canadian.

Cov neeg ua haujlwm tswj cov dej poob tau ntxiv rau cov roj-zoo cement slurries rau ntau tshaj 20 xyoo, thiab kev lag luam cementing niaj hnub no lees paub tias kev ua haujlwm zoo ntawm cementing tau zoo heev.Qhov tseeb, nws tau lees paub tias kev tswj xyuas cov dej tsis zoo tuaj yeem ua rau cov cementing tsis ua tiav los ntawm kev nce siab ntau dhau los yog kev sib tsoo ntawm cov cement, thiab cov cement filtrate ntxeem tau ntawm kev tsim yuav ua rau muaj kev phom sij rau kev tsim khoom.Cov kua dej poob additives tuaj yeem txhawb kev rov ua haujlwm zoo los ntawm kev tiv thaiv cov roj thiab roj txheej paug los ntawm cov dej lim ntxiv rau kev tswj xyuas cov dej tsis zoo ntawm cov cement slurry.
