Hydroxyethyl cellulose (HEC) yakakosha mvura-inonyungudika polima inoita basa rakakosha mukuchera oiri. Seyakagadzirwa neselulosi ine yakasarudzika yemuviri uye makemikari zvimiro, HEC inoshandiswa zvakanyanya mukuchera munhandare yemafuta uye mapurojekiti ekugadzira oiri.
1. Basic zvimiro zvehydroxyethyl cellulose (HEC)
Hydroxyethyl cellulose (HEC) isiri-ionic mvura-soluble polymer compound inowanikwa nekugadziriswa kwemakemikari echisikigo cellulose. Nekuunza mapoka e-hydroxyethyl muchimiro chemolecular ye cellulose, HEC ine hydrophilicity yakasimba, saka inogona kunyungudika mumvura kuti iite colloidal solution ine imwe viscosity. HEC ine yakagadzikana mamolecular chimiro, yakasimba kupisa kupisa, inert inert makemikari ehupfumi, uye haina chepfu, haina kunhuwa, uye ine biocompatibility yakanaka. Aya maitiro anoita HEC yakanakira kemikari yekuwedzera mukuchera oiri.
2. Mechanism yeHEC mukuchera mafuta
2.1 Kudzora kuchera fluid viscosity
Munguva yekuchera oiri, mvura yekuchera (inozivikanwawo sedhaka rekuchera) imvura yakakosha inoshanda, inonyanya kushandiswa kutonhodza nekuzora bhiti rekuchera, kutakura zvicherwa, kudzikamisa madziro etsime, uye kudzivirira kubuda. HEC, seyakakora uye rheology modifier, inogona kuvandudza kushanda kwayo nekugadzirisa viscosity uye rheological properties yekuchera mvura. Mushure mokunge HEC yanyunguduka mumvura yekuchera, inoumba hutatu-dimensional network structure, iyo inovandudza zvakanyanya viscosity yemvura yekuchera, nekudaro ichiwedzera simba rekutakura jecha remvura yekuchera, kuve nechokwadi chokuti kucheka kunogona kubudiswa zvakanaka kubva pasi petsime, uye kudzivirira kuvharika kwetsime.
2.2 Zvakanaka kugadzikana kwemadziro uye kudzivirira kudonha kwetsime
Zvakanaka kugadzikana kwemadziro inyaya yakakosha mukuchera engineering. Pamusana pekuoma kwechimiro chepasi pevhu uye kusiyana kwekumanikidzwa kunogadzirwa panguva yekuchera, tsime remadziro rinowanzoita kuparara kana kusagadzikana. Kushandiswa kweHEC mukuchera mvura kunogona kunyatso vandudza kusefa kudzora kugona kwemvura yekuchera, kuderedza kufirita kurasikirwa kwemvura yekuchera kusvika pakuumbwa, uyezve kugadzira keke rakasviba rematope, kunyatsovhara madiki madiki emadziro etsime, uye kudzivirira tsime remadziro kubva pakusagadzikana. Mhedzisiro iyi yakakosha zvikuru kuchengetedza kutendeseka kwemadziro etsime uye kudzivirira kudonha kwematsime, kunyanya mukuumbwa nekupenya kwakasimba.
2.3 Yakaderera yakasimba chikamu system uye zvakatipoteredza zvakanakira
Huwandu hwakakura hwezvimedu zvakasimba zvinowanzowedzerwa kune yechinyakare yekuchera mvura sisitimu yekuvandudza viscosity uye kugadzikana kwemvura yekuchera. Nekudaro, masisitimu akasimba akadai anowanzopfeka pamidziyo yekuchera uye anogona kukonzera kusvibiswa kwedhamu mukugadzirwa kwemafuta kunotevera. Semukobvu unoshanda, HEC inogona kuchengetedza yakanakira viscosity uye rheological zvimiro zvemvura yekuchera pasi pemamiriro eiyo yakaderera yakasimba yemukati, kuderedza kusakara pamidziyo, uye kuderedza kukuvadzwa kune reservoir. Mukuwedzera, HEC ine biodegradability yakanaka uye haizokonzeri kusvibiswa kusingaperi kune zvakatipoteredza. Naizvozvo, nekuwedzera kuomarara kwezvakatipoteredza zvinodiwa nhasi, mabhenefiti ekushandisa eHEC ari pachena.
3. Zvakanakira HEC mukuchera mafuta
3.1 Yakanaka solubility yemvura uye thickening maitiro
HEC, semvura inonyungudika yepolymer zvinhu, ine kunyungudika kwakanaka pasi pemamiriro akasiyana emhando yemvura (semvura yakachena, mvura yemunyu, nezvimwewo). Izvi zvinoita kuti HEC ishandiswe munzvimbo dzakasiyana-siyana dzakaoma dze geological, kunyanya munzvimbo dzakakwirira-munyu, uye inogona kuramba ichichengetedza kunaka kwekuita. Kuwedzera kwayo kwakakosha, iyo inogona kunyatso kuvandudza rheological zvimiro zvekuchera zvinwiwa, kuderedza dambudziko rekucheka deposition, uye kunatsiridza kuchera.
3.2 Yakanakisa tembiricha uye munyu kuramba
Mumvura yakadzika uye yakadzika-yakadzika mutsime, tembiricha yekugadzira uye kudzvanywa kwakakwira, uye mvura yekuchera inobatwa nyore nekupisa kwepamusoro uye kudzvinyirira kwakanyanya uye inorasikirwa nekuita kwayo kwepakutanga. HEC ine yakagadzika mamorekuru chimiro uye inogona kuchengetedza viscosity yayo uye rheological properties pakupisa kwakanyanya uye kumanikidza. Pamusoro pezvo, munzvimbo dzakagadzirwa nemunyu wakanyanya, HEC inogona kuramba yakakora yakanakira kudzivirira mvura yekuchera kubva mukudonhedza kana kukanganisa nekuda kwekukanganiswa kweion. Naizvozvo, HEC ine yakanakisa tembiricha uye munyu kuramba pasi pezvakaoma geological mamiriro uye inoshandiswa zvakanyanya mumatsime akadzika uye yakaoma mapurojekiti ekuchera.
3.3 Kunyatsoita lubrication kuita
Matambudziko eFriction panguva yekuchera zvakare chinhu chakakosha chinokanganisa kudhirowa. Seimwe yemafuta ekuchera mumvura yekuchera, HEC inogona kuderedza zvakanyanya friction coefficient pakati pematurusi ekuchera uye madziro emadziro, kuderedza kupfeka kwemidziyo, uye kuwedzera hupenyu hwebasa rematurusi ekuchera. Iyi ficha inonyanya kuzivikanwa mumatsime akatwasuka, akarerekera matsime uye mamwe matsime emhando, ayo anobatsira kudzikisa kuitika kwekutadza kwegomba uye kuvandudza kushanda kwese kushanda zvakanaka.
4. Kushanda kunoshanda uye zvidziviriro zveHEC
4.1 Dosing nzira uye yekutarisa kudzora
Iyo dosing nzira yeHEC inokanganisa zvakananga kupararira kwayo uye kupera kwemhedzisiro mukuchera mvura. Kazhinji, HEC inofanira kuwedzerwa zvishoma nezvishoma kumvura yekuchera pasi pemamiriro ezvinhu anomutsa kuti ive nechokwadi chokuti inogona kunyungudutswa zvakaenzana uye kudzivirira kusangana. Panguva imwecheteyo, kushandiswa kwekushandiswa kweHEC kunoda kudzorwa zvine musoro maererano nemamiriro ekuumbwa, kudhirowa kwemvura yekushanda zvinodiwa, nezvimwewo. nepo yakadzikira yakawandisa inogona kusakwanisa kushandisa zvizere kukora kwayo uye lubrication mhedzisiro. Nokudaro, kana uchishandisa HEC, inofanira kugadziriswa uye kugadziriswa maererano nemamiriro chaiwo.
4.2 Kuenderana nezvimwe zvinowedzera
Mune chaiyo yekuchera mvura masisitimu, akasiyana emakemikari ekuwedzera anowanzo kuwedzerwa kuti aite mabasa akasiyana. Naizvozvo, kugarisana pakati peHEC nezvimwe zvinowedzera zvakare chinhu chinoda kutariswa. HEC inoratidza kuwirirana kwakanaka nevakawanda vakajairika kudhiraivha zvinwiwa zvinowedzera senge fluid kurasikirwa reducers, lubricant, stabilizers, nezvimwewo, asi mune mamwe mamiriro ezvinhu, zvimwe zvinowedzera zvinogona kukanganisa kukora mhedzisiro kana solubility yeHEC. Naizvozvo, kana uchigadzira fomula, zvinodikanwa kunyatso funga nezvekudyidzana pakati pezviwedzere zvakasiyana-siyana kuti ive nechokwadi chekugadzikana uye kuwirirana kwekuita kwemvura yekuchera.
4.3 Kuchengetedzwa kwezvakatipoteredza uye kurapwa kwemvura yemarara
Nekuwedzera kuomesera kwemitemo yekuchengetedza kwezvakatipoteredza, hushamwari hwezvakatipoteredza hwemvura yekuchera hwakagamuchira zvishoma nezvishoma kutariswa. Sezvinhu zvine biodegradability yakanaka, kushandiswa kweHEC kunogona kunyatso kudzikisa kusvibiswa kwemvura yekuchera kune zvakatipoteredza. Zvisinei, mushure mokunge kuchera kwapera, tsvina yemvura ine HEC ichiri kudiwa kunyatsogadziriswa kuti irege migumisiro yakaipa pane zvakatipoteredza. Mukuita kurapwa kwemvura yemarara, nzira dzesainzi dzekurapa senge tsvina yekudzoreredza uye kushatisa dzinofanirwa kugamuchirwa pamwe chete nemirairo yekuchengetedzwa kwezvakatipoteredza uye zvinodiwa zvehunyanzvi kuona kuti kukanganisa kwezvakatipoteredza kunoderedzwa.
Hydroxyethyl cellulose (HEC) inoita basa rakakosha mukuchera oiri. Nekunyungudika kwayo kwemvura, kukora, tembiricha uye munyu kuramba uye lubrication maitiro, inopa mhinduro yakavimbika yekuvandudza mashandiro emvura yekuchera. Pasi pemamiriro ezvinhu akaoma e geological uye hutsinye hwekushanda nharaunda, kushandiswa kweHEC kunogona kunyatso vandudza kuchera, kuderedza kupfeka kwemidziyo, uye kuona kugadzikana kwegorofu. Nekuenderera mberi nekuenderera mberi kwehunyanzvi hweindasitiri yemafuta, tarisiro yekushandiswa kweHEC mukuchera oiri ichave yakakura.
