FC-650S Cov tshuaj ntxiv rau kev tswj cov kua dej poob
• FC-650S yog cov tshuaj polymer uas ua rau cov kua dej poob rau cov cement siv rau hauv cov roj qhov thiab tsim los ntawm kev sib xyaw nrog AMPS/NN/HA ua cov monomer tseem ceeb uas tiv taus kub thiab ntsev zoo thiab ua ke nrog lwm cov monomers tiv taus ntsev. Cov molecule muaj ntau pawg adsorptive xws li - CONH2, - SO3H, - COOH, uas ua lub luag haujlwm tseem ceeb hauv kev tiv taus ntsev, tiv taus kub, nqus dej dawb, txo dej poob, thiab lwm yam.
• FC-650S muaj kev hloov pauv zoo thiab siv tau rau ntau yam kev siv cement slurry. Nws muaj kev sib raug zoo nrog lwm cov khoom ntxiv.
• FC-650S siv tau rau qhov kub thiab txias dav dav uas tiv taus kub txog li 230 ℃. Nws muaj kev ruaj khov zoo dua hauv qhov chaw kub thiab txias vim yog kev qhia txog humic acid.
• FC-650S siv tau ib leeg xwb. Qhov txiaj ntsig zoo dua thaum siv ua ke nrog FC-631S/ FC-632S.
• Nws tsim nyog rau kev npaj cov dej tshiab/dej ntsev.
Cov chaw roj kub siab ntsib ntau yam teeb meem tshwj xeeb thaum nws los txog rau kev sib xyaw ua ke qhov dej. Ib qho ntawm cov teeb meem no yog qhov teeb meem ntawm kev poob kua, uas tuaj yeem tshwm sim thaum cov av nkos lim dej nkag mus rau hauv qhov chaw thiab ua rau cov kua dej tsawg dua. Txhawm rau daws qhov teeb meem no, peb tau tsim cov khoom siv txo cov kua dej uas tsim tshwj xeeb rau kev siv hauv cov chaw roj kub siab.

Cov tshuaj tswj kev poob kua tau raug qhia rau cov roj av hauv cov roj av slurries tau ntau tshaj 20 xyoo, thiab kev lag luam tau nkag siab tias qhov no tau txhim kho qhov zoo ntawm cov haujlwm cementing. Qhov tseeb, nws tau lees paub zoo tias qhov tsis muaj kev tswj kev poob kua yuav yog qhov ua rau muaj kev ua tsis tiav ntawm cov cementing thawj zaug vim yog qhov nce ntau dhau lossis annulus bridging thiab tias kev tsim los ntawm cement filtrate tuaj yeem ua rau muaj kev phom sij rau kev tsim khoom. Cov tshuaj ntxiv rau kev poob kua tsis yog tsuas yog txo cov cement slurry kua poob xwb tab sis kuj tseem tiv thaiv cov kua lim kom tsis txhob ua rau cov roj thiab cov roj txheej ua qias tuaj, txhim kho kev ua haujlwm rov qab.
