Sodium carboxymethyl cellulose (CMC-Na mwachidule) ndi yofunika kusungunuka polima polima pawiri ndipo amagwiritsidwa ntchito kwambiri pobowola mafuta. Makhalidwe ake apadera amapangitsa kukhala chinthu chofunikira kwambiri pakubowola madzimadzi.
1. Zinthu zofunikira za sodium carboxymethyl cellulose
Sodium carboxymethyl cellulose ndi anionic cellulose ether yopangidwa ndi mapadi pambuyo pa mankhwala amchere ndi chloroacetic acid. Mapangidwe ake a maselo ali ndi magulu ambiri a carboxymethyl, omwe amachititsa kuti azikhala ndi madzi osungunuka komanso okhazikika. CMC-Na imatha kupanga njira yowoneka bwino kwambiri m'madzi, yokhala ndi makulidwe, kukhazikika komanso kupanga mafilimu.
2. Kugwiritsa ntchito sodium carboxymethyl cellulose pobowola madzimadzi
Thickener
CMC-Na imagwiritsidwa ntchito ngati thickener pobowola madzimadzi. Ntchito yake yayikulu ndikuwonjezera kukhuthala kwamadzi obowola ndikukulitsa luso lake lonyamula miyala yodula ndikubowola. Kukhuthala koyenera kwamadzi obowola kungalepheretse bwino kugwa kwa khoma ndikusunga bata la chitsime.
Fluid loss reducer
Pa kubowola ndondomeko, pobowola madzimadzi kulowa mu pores mapangidwe, kuchititsa kutaya madzi mu madzimadzi pobowola, amene osati zinyalala pobowola madzimadzi, komanso kungachititse chitsime kugwa ndi posungira kuwonongeka. Monga chochepetsera kutaya madzimadzi, CMC-Na imatha kupanga keke wandiweyani wosefera pakhoma la chitsime, kuchepetsa kutayika kwa kusefera kwamadzi obowola ndikuteteza mapangidwe ndi khoma la chitsime.
Mafuta
Pobowola, kukangana pakati pa bowolo ndi khoma la chitsime kumapangitsa kutentha kwambiri, zomwe zimapangitsa kuti chida chobowola chiwonjezeke. Kupaka mafuta a CMC-Na kumathandiza kuchepetsa mikangano, kuchepetsa kuwonongeka kwa chida chobowola, komanso kukonza bwino pobowola.
Stabilizer
Kubowola madzimadzi akhoza flocculate kapena kunyozeka pansi pa kutentha ndi kuthamanga kwambiri, motero kutaya ntchito yake. CMC-Na ili ndi kukhazikika kwamafuta abwino komanso kukana kwa mchere, ndipo imatha kusunga kukhazikika kwamadzi obowola pansi pamikhalidwe yovuta ndikukulitsa moyo wake wautumiki.
3. Njira yogwiritsira ntchito sodium carboxymethyl cellulose
Kusintha kwa viscosity
Maselo a CMC-Na ali ndi magulu ambiri a carboxymethyl, omwe amatha kupanga ma hydrogen bond m'madzi kuti awonjezere kukhuthala kwa yankho. Posintha kulemera kwa maselo ndi kulowetsa digiri ya CMC-Na, kukhuthala kwamadzimadzi obowola kumatha kuyendetsedwa kuti zikwaniritse zosowa zosiyanasiyana zoboola.
Kuwongolera kusefera
Mamolekyu a CMC-Na amatha kupanga maukonde amitundu itatu m'madzi, omwe amatha kupanga keke wandiweyani pakhoma la chitsime ndikuchepetsa kutayika kwa kusefera kwamadzi obowola. Mapangidwe a keke ya fyuluta sizitengera kuchuluka kwa CMC-Na, komanso kulemera kwake kwa maselo ndi digirii yolowa m'malo.
Kupaka mafuta
Mamolekyu a CMC-Na amatha kudyedwa pamwamba pa kubowola ndi khoma la chitsime m'madzi kuti apange filimu yopaka mafuta ndikuchepetsa kugundana. Kuphatikiza apo, CMC-Na imathanso kuchepetsa kukangana pakati pa kubowola ndi khoma lachitsime mwakusintha kukhuthala kwamadzi obowola.
Kukhazikika kwamafuta
CMC-Na ikhoza kukhalabe yokhazikika pamapangidwe ake a maselo pansi pa kutentha kwakukulu ndipo sichimakonda kuwonongeka kwa kutentha. Izi ndichifukwa choti magulu a carboxyl m'mamolekyu ake amatha kupanga zomangira zokhazikika za haidrojeni ndi mamolekyu amadzi kuti asawonongeke ndi kutentha kwakukulu. Kuphatikiza apo, CMC-Na ilinso ndi kukana kwa mchere wabwino ndipo imatha kupitilizabe kugwira ntchito kwake pamapangidwe a saline.
4. Zitsanzo za Kugwiritsa Ntchito Sodium Carboxymethyl Cellulose
Pobowola kwenikweni, kugwiritsa ntchito sodium carboxymethyl cellulose ndikodabwitsa. Mwachitsanzo, pobowola chitsime chakuya, makina obowola omwe ali ndi CMC-Na adagwiritsidwa ntchito kuti azitha kukhazikika komanso kusefera kwa chitsime, kuwonjezera liwiro la kubowola, komanso kuchepetsa mtengo wobowola. Kuphatikiza apo, CMC-Na imagwiritsidwanso ntchito kwambiri pobowola panyanja, ndipo kukana kwake bwino mchere kumapangitsa kuti izichita bwino m'malo am'madzi.
Kugwiritsa ntchito sodium carboxymethyl cellulose pobowola madzimadzi makamaka kumaphatikizapo zinthu zinayi: makulidwe, kuchepetsa kutayika kwa madzi, kuthira mafuta ndi kukhazikika. Kapangidwe kake kapadera ka thupi ndi mankhwala kumapangitsa kukhala chinthu chofunikira kwambiri pakubowola madzimadzi. Ndikukula kosalekeza kwaukadaulo wakubowola, chiyembekezo chogwiritsa ntchito sodium carboxymethyl cellulose chidzakhala chokulirapo. Pakafukufuku wamtsogolo, mawonekedwe a mamolekyu ndi njira zosinthira za CMC-Na zitha kukonzedwa kuti zipititse patsogolo magwiridwe antchito ake ndikukwaniritsa zosowa za malo ovuta kwambiri obowola.
