Carboxymethyl cellulose (CMC) ndeyepamusoro molecular polymer inoshandiswa zvakanyanya mukuchera zvinwiwa zvine yakanaka rheological zvimiro uye kugadzikana. Iyo yakagadziridzwa cellulose, inonyanya kuumbwa nekuita seruseru ine chloroacetic acid. Nekuda kwekuita kwayo kwakanaka, CMC yakashandiswa zvakanyanya muminda yakawanda senge kuchera oiri, migodhi, kuvaka uye indasitiri yechikafu.
1. Zvivakwa zveCMC
Carboxymethyl cellulose ichena kusvika kuchiedza yeyero poda inoumba inoonekera colloidal mhinduro kana yakanyungudutswa mumvura. Chimiro chayo chemakemikari chine carboxymethyl mapoka, izvo zvinoita kuti ive yakanaka hydrophilicity uye lubricity. Pamusoro pezvo, iyo viscosity yeCMC inogona kudzorwa nekugadzirisa huremu hwayo hwemamorekuru uye kutarisisa, izvo zvinoita kuti kushandiswa kwayo mukuchera zvinwiwa zvive zvakanyanya kushanduka.
2. Basa mukuchera zvinwiwa
Panguva yekuchera, kuita kwemvura yekuchera kwakakosha. CMC inotamba anotevera mabasa makuru mukuchera zvinwiwa:
Thickener: CMC inogona kuwedzera viscosity yemvura yekuchera, nekudaro ichiwedzera kutakura kwavo, kuchengetedza yakaturikwa yakasimba particles, uye kudzivirira sedimentation.
Rheology modifier: Nekugadzirisa rheological zvimiro zvekuchera mvura, CMC inogona kuvandudza kuyerera kwayo kuitira kuti irambe ichichengetedza mvura yakanaka pasi petembiricha yakanyanya uye yakanyanya kudzvanywa mamiriro.
Plug agent: CMC zvimedu zvinogona kuzadza matombo akatsemuka, zvinonyatso kudzikisa kurasikirwa kwemvura uye kunatsiridza kuchera.
Lubricant: Kuwedzerwa kweCMC kunogona kuderedza kupokana pakati pechibooreso uye madziro etsime, kuderedza kupera uye kuwedzera kumhanya kwekuchera.
3. Zvakanakira CMC
Kushandisa carboxymethyl cellulose sekuwedzera kwemvura yekuchera kune zvinotevera zvakanakira:
Iine hushamwari kwezvakatipoteredza: CMC ndeye yakasikwa polymer zvinhu zvine yakanaka biodegradability uye kushoma kukanganisa nharaunda.
Mutengo-kushanda: Kuenzaniswa nemamwe mapolymer ekugadzira, CMC ine mutengo wakaderera, kuita kwakanakisa uye kudhura kwakanyanya.
Tembiricha uye salinity kuchinjika: CMC inogona kuramba yakagadzikana kuita mukupisa kwakanyanya uye yakakwirira munyu nharaunda uye inoenderana neakasiyana emamiriro e geological.
4. Mienzaniso yekushandisa
Mukushandisa chaiko, makambani mazhinji emafuta akabudirira kushandisa CMC kune akasiyana mapurojekiti ekuchera. Semuyenzaniso, mune mamwe tembiricha yakakwira uye matsime ekumanikidza, kuwedzera huwandu hwakakodzera hweCMC kunogona kunyatso kudzora rheology yedhaka uye kuve nechokwadi chekuchera. Uye zvakare, mune mamwe maumbirwo akaomarara, kushandisa CMC senge plugging agent inogona kuderedza zvakanyanya kurasikirwa kwemvura uye kunatsiridza kuchera.
5. Chengetedzo
Kunyangwe CMC ine akawanda mabhenefiti, anotevera mapoinzi anofanirawo kucherechedzwa panguva yekushandiswa:
Chikamu: Gadzirisa huwandu hweCMC yakawedzerwa zvinoenderana nemamiriro chaiwo. Kushandisa zvakanyanya kunogona kukonzera kuderera kwemvura.
Mamiriro ekuchengetedza: Inofanirwa kuchengetwa munzvimbo yakaoma uye inotonhorera kudzivirira hunyoro hunokanganisa kushanda.
Kusanganisa zvakaenzana: Paunenge uchigadzira mvura yekuchera, ita shuwa kuti CMC yanyungudika zvizere kudzivirira kuunganidzwa kwechikamu.
Kushandiswa kwecarboxymethyl cellulose mukuchera mvura hakungonatsiridza kugona kuchera uye kuderedza mutengo, asi zvakare kunosimudzira kuvandudzwa kwehunyanzvi hwekuchengetedza nharaunda kusvika pamwero wakati. Nekufambira mberi kwesainzi uye tekinoroji, huwandu hwekushandisa kweCMC huchawedzerwa, uye tinotarisira kuita basa rakakura mumapurojekiti ekuchera.
