FC-634S Cov Tshuaj Ntxiv Rau Kev Tswj Xyuas Kev Poob Dej Kub Siab
• FC-634S 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 ua cov monomer tseem ceeb nrog kev tiv taus kub thiab ntsev zoo thiab ua ke nrog lwm cov monomers tiv thaiv ntsev. Cov khoom tau qhia cov pab pawg uas tsis yooj yim rau hydrolyze kom qhov kev tiv taus kub siab tau txhim kho ntau heev. Cov molecule muaj ntau cov pab 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-634S 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-634S muaj viscosity siab ntawm qhov nrawm qis, uas tuaj yeem txhim kho qhov ruaj khov ntawm lub kaw lus cement slurry, tswj qhov fluidity ntawm slurry, tiv thaiv kev sedimentation tib lub sijhawm, nws muaj kev ua tau zoo tiv thaiv roj channeling, qhov viscosity ntawm qhov nrawm qis qis dua FC-632S.
• FC-634S siv tau rau qhov kub thiab txias dav dav thiab tiv taus kub txog li 230 ℃. Tom qab siv, cov kua ntawm cov cement slurry system zoo, ruaj khov nrog cov kua tsawg dua thiab tsis muaj kev ncua thiab lub zog thaum ntxov ntawm qhov kub qis sai sai. Nws siv tau rau kev npaj cov dej tshiab/dej ntsev slurry.
Foring Chemical FLCA yog cov tshuaj polymeric pheej yig uas tsim los txo cov kua dej poob thaum kub thiab siab (HTHP) uas siv tau zoo rau ntau yam xwm txheej thiab kev xav tau, xws li kub thiab ntsev ntau. FC-634S yog cov tshuaj tswj kev poob dej kub thiab nws tsim nyog rau kev lag luam Lavxias thiab North American.

Cov tshuaj tswj kev poob kua tau raug qhia rau cov roj-qhov av cement slurries rau ntau tshaj 20 xyoo, thiab kev lag luam cementing tau pom tias muaj kev txhim kho zoo hauv 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 ntom ntom ntau dhau lossis annulus bridging, thiab tias cement filtrate nkag mus rau hauv qhov tsim yuav ua rau muaj kev puas tsuaj rau cov zis. Cov tshuaj ntxiv rau kev poob kua tuaj yeem pab cov cement slurry rov qab zoo dua los ntawm kev tiv thaiv cov roj thiab cov roj txheej ua qias tuaj nrog rau kev tswj kev poob kua ntawm cov cement slurry.
