FC-605S Cov Tshuaj Ntxiv rau Kev Tswj Xyuas Kev Poob Kua
• FC-605S 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 ua cov monomer tseem ceeb nrog kev tiv taus kub thiab ntsev zoo thiab ua ke nrog lwm cov monomers tiv thaiv 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-605S 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 thiab ua lub luag haujlwm hauv kev txhawb nqa viscosity thiab kev ncua vim nws qhov hnyav molecular loj.
• FC-605S yog tsim rau qhov kub thiab txias dav dav nrog kev tiv taus kub siab txog li 180 ℃. Tom qab siv, qhov fluidity ntawm cov cement slurry system zoo, ruaj khov nrog tsawg dua cov kua dawb thiab tsis muaj kev ncua kev teeb tsa thiab lub zog tsim sai.
• FC-605S yog tsim rau kev npaj cov dej tshiab/dej ntsev.
Foring Chemical FLCA yog cov tshuaj polymeric pheej yig uas tsim los txo cov kua dej poob hauv qhov kub thiab txias siab (HTHP) uas siv tau zoo rau ntau yam xwm txheej thiab kev xav tau, xws li qhov kub thiab txias siab thiab cov ntsev ntau. FC-605S yog ib qho kev daws teeb meem txhim khu kev qha thiab zoo rau kev daws teeb meem cov kua dej poob thaum lub sijhawm ua cov roj av cementing.

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.
