FC-610S Cov tshuaj ntxiv rau kev tswj cov kua dej poob
• FC-610S yog ib qho tshuaj polymer uas ua rau cov cement poob dej siv rau hauv cov qhov dej roj uas tau tsim los ntawm kev sib xyaw ua ke nrog AMPS ua lub monomer tseem ceeb thiab lwm cov monomers tiv thaiv ntsev. Nws muaj kev tiv taus kub thiab ntsev zoo. Cov khoom muaj cov pab pawg ntxiv uas nyuaj rau hydrolyze, ua rau kev tiv taus kub siab zoo dua. Qhov muaj ntau pawg adsorptive heev hauv cov molecules, xws li CONH2, SO3H, thiab COOH, yog qhov tseem ceeb rau cov molecules lub peev xwm tiv taus ntsev, tswj qhov kub tas li, nqus dej dawb, thiab txo cov dej poob, ntawm lwm yam khoom.
• FC-610S 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-610S siv tau rau qhov kub thiab txias dav dav nrog kev tiv taus kub siab txog li 230 ℃. Tom qab siv, qhov dej ntawm cov cement slurry system zoo, ruaj khov nrog cov kua tsawg dua thiab tsis muaj kev ncua kev teeb tsa thiab lub zog tsim sai.
• FC-610S yog tsim 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 tshwj xeeb uas tau tsim tshwj xeeb rau kev siv hauv cov chaw roj kub siab. FC-610S yog ib hom tshuaj tswj kev poob kua thiab nws tsim nyog rau kev lag luam Middle East.

Tau ntau tshaj 20 xyoo, cov tshuaj tswj kev poob kua tau ntxiv rau hauv cov roj av cement slurries thiab tam sim no nws tau lees paub hauv kev lag luam tias qhov zoo ntawm cov haujlwm cementing tau zoo dua qub. Tseeb tiag, nws feem ntau lees paub meej tias tsis muaj kev tswj kev poob kua yuav yog lub luag haujlwm rau kev ua tsis tiav ntawm cov cementing thawj zaug, vim yog qhov ntom ntom 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 tsuas yog tuaj yeem tswj tau qhov poob kua ntawm cov cement slurry, tab sis kuj tiv thaiv cov roj thiab cov roj txheej kom tsis txhob raug kuab paug los ntawm cov kua lim thiab yog li ua rau kom muaj kev rov zoo dua.
