Pa kubowola, kubowola ndi workover mafuta ndi gasi zachilengedwe, khoma chitsime sachedwa kutaya madzi, kuchititsa kusintha kwa m'mimba mwake ndi kugwa, kotero kuti ntchito sangathe kuchitidwa bwinobwino, kapena ngakhale kusiyidwa theka.Choncho, m'pofunika kusintha magawo a thupi la matope obowola malinga ndi kusintha kwa chilengedwe cha dera lililonse, monga kuya, kutentha, ndi makulidwe.CMC ndiye chinthu chabwino kwambiri chomwe chimatha kusintha magawo awa.Ntchito zake zazikulu ndi izi:
Matope omwe ali ndi CMC amatha kupanga khoma lachitsime kukhala keke yopyapyala, yolimba komanso yocheperako, yomwe ingalepheretse kutsitsa kwa shale, kuteteza kudula kuti zisabalalike, ndikuchepetsa kugwa kwa khoma.
Matope okhala CMC ndi mtundu wa mkulu-mwachangu madzi kutaya kuwononga wothandizila, akhoza kulamulira kutaya madzi pa mlingo bwino pa mlingo wochepa (0.3-0.5%), ndipo sizidzachititsa mavuto ena katundu matope. , monga kukhuthala kwambiri kapena kumeta ubweya.
Matope okhala ndi CMC amatha kukana kutentha kwambiri, ndipo nthawi zambiri amatha kugwiritsidwa ntchito kumalo otentha kwambiri a 140 ° C, monga zinthu zolowa m'malo komanso zowoneka bwino kwambiri, zitha kugwiritsidwa ntchito kumalo otentha kwambiri a 150-170. °C.
Matope okhala ndi CMC samva mchere.Makhalidwe a CMC ponena za kukana kwa mchere ndi: sikungathe kukhalabe ndi mphamvu zabwino zochepetsera kutaya kwa madzi pansi pa mchere wina, koma zimatha kukhalabe ndi katundu wina wa rheological, womwe uli ndi kusintha pang'ono poyerekeza ndi malo a madzi abwino. ;ndi zonse Atha kugwiritsidwa ntchito pobowola dongo wopanda madzimadzi ndi matope m'malo amchere amchere.Madzi ena obowola amatha kukana mchere, ndipo mawonekedwe a rheological sasintha kwambiri.Pansi pa 4% mchere wa mchere ndi madzi abwino, kusintha kwa viscosity kusintha kwa CMC yosamva mchere kwawonjezeka kufika pa 1, ndiko kuti, kukhuthala sikungasinthidwe m'malo amchere wambiri.
Matope okhala ndi CMC amatha kuwongolera matope.CMCsangathe kuchepetsa kutaya madzi, komanso kuonjezera mamasukidwe akayendedwe.
1. Matope okhala ndi CMC amatha kupanga khoma lachitsime kukhala keke yopyapyala, yolimba komanso yocheperako, kuchepetsa kutaya kwa madzi.Pambuyo powonjezera CMC kumatope, chobowolacho chikhoza kupeza mphamvu yochepetsetsa yoyambira, kotero kuti matope amatha kumasula mpweya wokulungidwa mmenemo, ndipo panthawi imodzimodziyo, zinyalala zimatha kutayidwa mwamsanga mu dzenje lamatope.
2. Monga ma dispersions ena kuyimitsidwa, matope kubowola ali ndi alumali moyo.Kuwonjezera CMC kumatha kupangitsa kuti ikhale yokhazikika ndikutalikitsa moyo wa alumali.
3. Matope omwe ali ndi CMC samakhudzidwa kawirikawiri ndi nkhungu, ndipo palibe chifukwa chokhalira ndi pH yamtengo wapatali ndikugwiritsa ntchito zotetezera.
4. Matope okhala ndi CMC amakhala okhazikika bwino ndipo amatha kuchepetsa kutaya kwa madzi ngakhale kutentha kuli pamwamba pa madigiri 150.
