FC-620S Fluid Poob Control additives
• FC-620S yog ib tug polymer kua loss additiverau cement siv nyob rau hauvvaj avthiab tsim los ntawm copolymerization nrogAMPSraws li qhov tseem ceebmonomer nrog kub zoo thiab ntsev tsis kamthiab ua ke nrog lwm cov tshuaj tiv thaiv ntsevmonomers.Covmolecules muaj ib tug loj tus naj npawb ntawm adsorptive pawg xws li - CONH2, - SO3H, - COOH, uas ua sislub luag haujlwm tseem ceeb hauv kev tiv thaiv ntsev, kub tsis kam, nqus dej dawb, txo qis dej, thiab lwm yam.
• FC-620S haum rau qhov kub thiab txiasnrogkub kub tsis kam mus txog 150 ℃.Tom qab siv, lubfluidity ntawm cement slurry systemyog qhov zoo, ruaj khov nrog cov kua dej tsawg dua thiab tsis muaj teeb meem retarding thiab lub zog loj hlob sai.
•FC-620 Sishaum rau ntau yam dej hiav txwv cement slurry systems.Nws muaj zoo compatibility nrog lwm yam additives.
•FC-620S muaj qhov muaj zog dispersibility, tshwj xeeb tshaj yog tsim rau cov dej tshiab cement slurry systems nrog cov ntsiab lus siab lossis cov ntaub ntawv muaj txiaj ntsig zoo.
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.

Tau ntau tshaj 20 xyoo, cov neeg ua haujlwm tswj cov dej tsis zoo tau ntxiv rau cov roj-zoo cement slurries thiab tam sim no tau lees paub hauv kev lag luam tias kev ua haujlwm zoo ntawm cementing tau zoo dua.Qhov tseeb, nws yog feem ntau lees paub tias qhov tsis muaj kev tswj xyuas cov dej tsis zoo yuav ua rau lub luag haujlwm tseem ceeb hauv kev ua haujlwm cementing tsis ua haujlwm, vim tias qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom tsim cov khoom siv ua kom zoo nkauj.Cov kua dej poob additive tuaj yeem tsis tsuas yog tswj cov kua dej poob ntawm cov cement slurry, tab sis kuj tiv thaiv cov roj thiab roj txheej los ntawm kev ua qias tuaj los ntawm cov kua lim dej thiab yog li ua kom rov qab ua haujlwm tau zoo.
