Sodium carboxymethyl cellulose (CMC-Na kwenguva pfupi) yakakosha mumvura inonyungudika yepolymer compound uye inoshandiswa zvakanyanya mumafuta ekuchera mafuta. Hunhu hwayo hwakasiyana hunoita kuti ive chinhu chakakosha mudhill fluid system.
1. Zvinhu zvakakosha zve sodium carboxymethyl cellulose
Sodium carboxymethyl cellulose is anionic cellulose ether inogadzirwa ne cellulose mushure mekurapa alkali uye chloroacetic acid. Yayo molecular chimiro ine nhamba huru yemapoka e-carboxymethyl, iyo inoita kuti ive yakanaka yekunyungudika kwemvura uye kugadzikana. CMC-Na inogona kuumba yakakwira-viscosity mhinduro mumvura, ine gobvu, kudzikamisa uye firimu-kugadzira zvinhu.
2. Kushandiswa kwe sodium carboxymethyl cellulose mumvura yekuchera
Thickener
CMC-Na inoshandiswa seyakakora mumvura yekuchera. Basa rayo guru nderekuwedzera viscosity yemvura yekuchera uye kuwedzera kukwanisa kwayo kutakura matombo ekucheka uye kucheka kwekucheka. Iyo yakakodzera viscosity yekuchera mvura inogona kudzivirira zvakanaka kudonha kwemadziro uye kuchengetedza kugadzikana kwetsime.
Fluid loss reducer
Munguva yekuchera, mvura yekuchera inopinda mumapores ekuumbwa, ichikonzera kurasikirwa kwemvura mumvura yekuchera, iyo isingangoparadzi mvura yekuchera, asi inogona kukonzera kudonha kwemadziro uye kukuvadzwa kwemvura. Seyekuderedza kurasikirwa kwemvura, CMC-Na inogona kugadzira keke yakaonda sefa pamadziro etsime, ichinyatso kudzikisa kurasikirwa kwekusefa kwemvura yekuchera uye kudzivirira kuumbwa uye tsime madziro.
Lubricant
Munguva yekuchera, kupokana pakati pechibhorani nemadziro emugodhi kunoburitsa kupisa kwakawanda, zvichikonzera kuwedzera kupera kwechidhiro. Iyo lubricity yeCMC-Na inobatsira kuderedza kupokana, kuderedza kusakara kwechibooreso chekushandisa, uye kunatsiridza kuchera.
Stabilizer
Mvura yekuchera inogona kuyerera kana kudzikisira pasi pekupisa kwakanyanya uye kudzvanywa kwakanyanya, nekudaro kurasikirwa nebasa rayo. CMC-Na ine kugadzikana kwakanaka kwekupisa uye kuramba kwemunyu, uye inogona kuchengetedza kugadzikana kwemvura yekuchera pasi pemamiriro ezvinhu akaomarara uye kuwedzera hupenyu hwayo hwesevhisi.
3. Maitiro ekuita kwe sodium carboxymethyl cellulose
Viscosity kugadzirisa
Iyo molecular chimiro cheCMC-Na ine nhamba huru yemapoka e-carboxymethyl, ayo anogona kuumba hydrogen zvisungo mumvura kuwedzera viscosity yemhinduro. Nekugadzirisa huremu hwemamorekuru uye kutsiva dhigirii reCMC-Na, viscosity yemvura yekuchera inogona kudzorwa kuti isangane nezvinodiwa zveakasiyana mamiriro ekuchera.
Filtration control
CMC-Na mamorekuru anogona kugadzira matatu-dimensional network dhizaini mumvura, iyo inogona kugadzira dense sefa keke pamadziro etsime uye kuderedza kufirita kurasikirwa kwemvura yekuchera. Kuumbwa kwekeke resefa kunoenderana kwete chete nekusangana kweCMC-Na, asiwo pahuremu hwayo hwemamorekuru uye dhigirii rekutsiva.
Lubrication
CMC-Na mamorekuru anogona adsorbed pamusoro pechibooreso bhiti uye tsime rusvingo mumvura kuumba lubricating firimu uye kuderedza friction coefficient. Uye zvakare, CMC-Na inogona zvakare zvisina kunanga kuderedza kupokana pakati pechibooreso uye madziro etsime nekugadzirisa viscosity yemvura yekuchera.
Thermal kugadzikana
CMC-Na inogona kuchengetedza kugadzikana kweiyo molecular chimiro pasi pemamiriro ekushisa kwepamusoro uye haina kutarisana nekupisa kwekupisa. Izvi zvinodaro nekuti mapoka ecarboxyl mumamorekuru ayo anogona kuumba yakagadzikana mabhondi ehydrogen nemamorekuru emvura kuti arambe kukuvara kwakanyanya. Uye zvakare, CMC-Na zvakare ine yakanaka yemunyu kuramba uye inogona kuchengetedza kuita kwayo mukuumbwa kwesaline.
4. Mienzaniso Yekushandisa yeSodium Carboxymethyl Cellulose
Mukuita kuchera chaiko, mashandisirwo e sodium carboxymethyl cellulose zvinoshamisa. Semuyenzaniso, muchirongwa chekuchera tsime rakadzika, chidhiraivho chemvura chine CMC-Na chakashandiswa kunyatso kudzora kugadzikana uye kurasikirwa nekusefa kwegomba, kuwedzera kumhanya kwekuchera, uye kuderedza mutengo wekuchera. Pamusoro pezvo, CMC-Na inoshandiswawo zvakanyanya mukuchera mugungwa, uye kumira kwayo kwakanaka kwemunyu kunoita kuti iite zvakanaka munharaunda yegungwa.
Kushandiswa kwesodium carboxymethyl cellulose mukuchera mvura kunonyanya kusanganisa zvinhu zvina: kukora, kuderedza kurasikirwa kwemvura, kuzora uye kudzikamisa. Hunhu hwayo hwakasiyana hwepanyama uye hwemakemikari hunoita kuti ive chinhu chakakosha mukudhirowa kwemvura system. Nekuenderera mberi kwekuvandudza tekinoroji yekuchera, tarisiro yekushandiswa kwesodium carboxymethyl cellulose ichave yakakura. Mukutsvagisa kweramangwana, chimiro chemolecular uye nzira dzekugadzirisa dzeCMC-Na dzinogona kuvandudzwa kuti ienderere mberi nekuvandudza mashandiro ayo uye kusangana nezvinodiwa zvenzvimbo dzakaomesesa dzekuchera.
