Hydroxyethyl cellulose (HEC) ndi polima wofunikira wosungunuka m'madzi yemwe amagwira ntchito yofunikira pakubowola mafuta. Monga chochokera ku cellulose chokhala ndi mawonekedwe apadera akuthupi ndi mankhwala, HEC imagwiritsidwa ntchito kwambiri pobowola malo opangira mafuta ndi kupanga mafuta.
1. Basic katundu wa hydroxyethyl cellulose (HEC)
Hydroxyethyl cellulose (HEC) ndi polima yosungunuka m'madzi yopanda maayoni yomwe imapezeka posintha ma cellulose achilengedwe. Poyambitsa magulu a hydroxyethyl m'maselo a cellulose, HEC ili ndi hydrophilicity yamphamvu, kotero imatha kusungunuka m'madzi kuti ipange njira yothetsera colloidal ndi viscosity inayake. HEC ili ndi mawonekedwe okhazikika a mamolekyu, kukana kutentha kwamphamvu, katundu wocheperako wamankhwala, ndipo ndi yopanda poizoni, yopanda fungo, ndipo ili ndi biocompatibility yabwino. Makhalidwewa amapangitsa HEC kukhala chowonjezera chamankhwala choyenera pakubowola mafuta.
2. Njira ya HEC pakubowola mafuta
2.1 Kuwongolera kukhuthala kwamadzimadzi
Pobowola mafuta, madzi akubowola (omwe amadziwikanso kuti matope obowola) ndi madzi ofunikira kwambiri, omwe amagwiritsidwa ntchito kwambiri kuziziritsa ndi kuthira mafuta pobowola, kunyamula zodulidwa, kukhazikika pakhoma la chitsime, ndikuletsa kuphulika. HEC, monga thickener ndi rheology modifier, akhoza kusintha magwiridwe ake ntchito ndi kusintha mamasukidwe akayendedwe ndi rheological katundu pobowola madzimadzi. Pambuyo HEC imasungunuka mumadzimadzi obowola, imapanga mawonekedwe atatu amtundu wa maukonde, omwe amathandizira kwambiri kukhuthala kwamadzimadzi obowola, potero kumawonjezera mphamvu yonyamula mchenga wamadzimadzi obowola, kuonetsetsa kuti zodulidwazo zitha kutulutsidwa bwino. pansi pa chitsime, ndikuletsa kutsekeka kwa zitsime.
2.2 Kukhazikika kwa khoma komanso kupewa kugwa kwa chitsime
Kukhazikika kwa khoma ndizovuta kwambiri pakubowola engineering. Chifukwa cha zovuta zamapangidwe apansi panthaka komanso kusiyana kwapakati komwe kumachitika panthawi yobowola, khoma lachitsime nthawi zambiri limakonda kugwa kapena kusakhazikika. Kugwiritsa ntchito HEC pobowola madzimadzi kumatha kuwongolera luso la kusefera pakubowola madzimadzi, kuchepetsa kusefera kwamadzimadzi obowola kuti apange mapangidwe, kenako kupanga keke yamatope, kumangika bwino ming'alu yaying'ono ya khoma la chitsime, ndikuletsa khoma bwino kusakhazikika. Izi ndizofunika kwambiri pakusunga umphumphu wa khoma la chitsime ndikupewa kugwa bwino, makamaka m'mapangidwe omwe ali ndi mphamvu zodutsa.
2.3 Low olimba gawo dongosolo ndi ubwino chilengedwe
Kuchuluka kwa particles olimba nthawi zambiri anawonjezera kuti mwambo pobowola madzimadzi dongosolo kusintha mamasukidwe akayendedwe ndi bata la pobowola madzimadzi. Komabe, tinthu tating'onoting'ono tomwe timatha kuvala pazida zobowolera ndipo titha kuwononga malo osungira popanga chitsime chamafuta. Monga thickener imayenera, HEC ikhoza kukhala ndi kukhuthala koyenera komanso mawonekedwe a rheological amadzimadzi obowola pansi pa zinthu zotsika zolimba, kuchepetsa kuvala kwa zida, ndikuchepetsa kuwonongeka kwa posungira. Kuonjezera apo, HEC ili ndi biodegradability yabwino ndipo sichidzayambitsa kuipitsa kwamuyaya kwa chilengedwe. Chifukwa chake, ndizomwe zikuchulukirachulukira zoteteza zachilengedwe masiku ano, zabwino zogwiritsira ntchito HEC ndizodziwikiratu.
3. Ubwino wa HEC pakubowola mafuta
3.1 Kusungunuka kwamadzi bwino komanso kukhuthala
HEC, monga ma polima osungunuka m'madzi, imakhala ndi kusungunuka kwabwino pansi pamikhalidwe yosiyanasiyana yamadzi (monga madzi abwino, madzi amchere, etc.). Izi zimathandiza HEC kuti igwiritsidwe ntchito m'malo osiyanasiyana ovuta a geological, makamaka m'malo okhala ndi mchere wambiri, ndipo ikhoza kukhalabe ndi ntchito yabwino yokhuthala. Kukhuthala kwake kumakhala kofunikira, komwe kumatha kusintha bwino ma rheological amadzimadzi obowola, kuchepetsa vuto la ma cuttings, ndikuwongolera kubowola bwino.
3.2 Kutentha kwabwino kwambiri komanso kukana mchere
Pobowola bwino kwambiri komanso mozama kwambiri, kutentha kwa mapangidwe ndi kupanikizika kumakhala kwakukulu, ndipo madzi obowola amakhudzidwa mosavuta ndi kutentha kwakukulu ndi kuthamanga kwambiri ndipo amataya ntchito yake yoyamba. HEC ili ndi dongosolo lokhazikika la maselo ndipo limatha kukhala ndi viscosity ndi rheological properties pa kutentha kwakukulu ndi kupanikizika. Kuonjezera apo, m'malo opangidwa ndi mchere wambiri, HEC ikhoza kukhalabe ndi mphamvu yowonjezera yowonjezera kuti madzi obowola asagwedezeke kapena kusokoneza chifukwa cha kusokonezeka kwa ion. Chifukwa chake, HEC imakhala ndi kutentha kwambiri komanso kukana kwa mchere pansi pazovuta za geological ndipo imagwiritsidwa ntchito kwambiri m'zitsime zakuya komanso ntchito zoboola zovuta.
3.3 Kuchita bwino kwa mafuta
Mavuto akukangana pakubowola ndi chinthu chofunikira kwambiri chomwe chimakhudza kuyendetsa bwino ntchito. Monga imodzi mwamafuta opangira madzi akubowola, HEC imatha kuchepetsa kwambiri mikangano pakati pa zida zobowola ndi makoma a chitsime, kuchepetsa kuvala kwa zida, ndikuwonjezera moyo wautumiki wa zida zobowola. Izi zimawonekera makamaka m'zitsime zopingasa, zitsime zokhotakhota ndi mitundu ina yachitsime, zomwe zimathandizira kuchepetsa kulephera kwa kutsitsa ndikuwongolera magwiridwe antchito.
4. Kugwiritsa ntchito moyenera ndi kusamala kwa HEC
4.1 Dosing njira ndi ndende kulamulira
The dosing njira HEC mwachindunji zimakhudza kubalalitsidwa ndi kuvunda zotsatira pobowola madzimadzi. Nthawi zambiri, HEC iyenera kuwonjezeredwa pang'onopang'ono kumadzimadzi obowola pansi poyambitsa mikhalidwe kuti iwonetsetse kuti imatha kusungunuka mofanana ndikupewa kuphatikizika. Panthawi imodzimodziyo, kugwiritsidwa ntchito kwa HEC kumafunika kuyendetsedwa moyenerera malinga ndi mapangidwe a mapangidwe, kukumba zofunikira zamadzimadzi, ndi zina zotero. pamene otsika kwambiri ndende mwina sangathe mokwanira thickening ndi kondomu zotsatira zake. Chifukwa chake, mukamagwiritsa ntchito HEC, iyenera kukonzedwa ndikusinthidwa malinga ndi momwe zilili.
4.2 Kugwirizana ndi zina zowonjezera
M'machitidwe enieni obowola madzimadzi, zowonjezera zosiyanasiyana za mankhwala nthawi zambiri zimawonjezeredwa kuti zikwaniritse ntchito zosiyanasiyana. Choncho, kugwirizana pakati pa HEC ndi zina zowonjezera ndizofunikiranso zomwe ziyenera kuganiziridwa. HEC imasonyeza kuyanjana kwabwino ndi zowonjezera zowonjezera zamadzimadzi zomwe zimagwiritsidwa ntchito pobowola monga zochepetsera kutaya madzi, mafuta odzola, stabilizers, ndi zina zotero, koma pansi pazifukwa zina, zowonjezera zina zingakhudze kuwonjezereka kapena kusungunuka kwa HEC. Chifukwa chake, popanga chilinganizo, ndikofunikira kuganizira mozama kugwirizana pakati pa zowonjezera zosiyanasiyana kuti zitsimikizire kukhazikika komanso kusasinthika kwa magwiridwe antchito amadzimadzi.
4.3 Kuteteza chilengedwe ndi chithandizo chamadzi otayira
Ndi malamulo okhwimitsa kwambiri oteteza chilengedwe, kuyanjanitsa kwachilengedwe kwamadzi akubowola pang'onopang'ono kwalandira chidwi. Monga zinthu zomwe zili ndi biodegradability yabwino, kugwiritsa ntchito HEC kumatha kuchepetsa kuipitsidwa kwamadzi obowola ku chilengedwe. Komabe, pambuyo pobowola, madzi otayika omwe ali ndi HEC amafunikabe kusamalidwa bwino kuti apewe zotsatira zoipa pa malo ozungulira. Pochiza zinyalala zamadzimadzi, njira zochiritsira zasayansi monga kubwezeretsedwa kwamadzi otayira ndi kuwonongeka ziyenera kutsatiridwa limodzi ndi malamulo amderali oteteza chilengedwe komanso zofunikira zaukadaulo kuti zitsimikizire kuti chilengedwe chikuchepa.
Hydroxyethyl cellulose (HEC) imagwira ntchito yofunikira pakubowola mafuta. Ndi bwino kusungunuka kwamadzi, kukhuthala, kutentha ndi kukana mchere komanso kutsekemera, kumapereka njira yodalirika yopititsira patsogolo ntchito zamadzimadzi obowola. Pansi pa zovuta zachilengedwe komanso malo ogwirira ntchito movutikira, kugwiritsa ntchito HEC kumatha kupititsa patsogolo kubowola bwino, kuchepetsa kuvala kwa zida, ndikuonetsetsa kuti chitsime chikhazikika. Ndi kupita patsogolo kosalekeza kwaukadaulo wamakampani amafuta, chiyembekezo chogwiritsa ntchito HEC pakubowola mafuta chidzakhala chokulirapo.
