Hydxyethyl cellulose yemhando yepetroleum (HEC), semuchina unokosha we polymer unonyungudika mumvura, rheology modifier, uye stabilizer, zvave zvichikosha zvikuru mumunda wekubvisa mafuta negasi mumakore achangopfuura. Nekuwedzera kuri kuramba kuchiita matsime akadzika, matsime akadzika zvakanyanya, uye kutsvaga mafuta negasi kusingawanzoitiki, kudiwa kukuru kuri kuiswa pakushanda kwemvura yekuboorera, mvura yekupwanya, uye mvura yekupedzisa. HEC, nekunyungudika kwayo kwakanaka, kugadzikana kwemakemikari, uye kugona kwayo kukora, yave chinhu chakakosha chekuvandudza kushanda kwemafuta negasi.
HEC yemhando yepeturu inoratidza kugona kunyungudika kwemvura uye kukora kwayo, ichikurumidza kugadzira sisitimu yakafanana pakugadzira mvura yekuboora, ichiwedzera kusimba kwemvura, uye nokudaro ichivandudza kugona kwekutakura zvidimbu. Panguva yekuboora, zvidimbu zviri pasi petsime zvinofanirwa kubviswa zvinobudirira mumamiriro ekupisa kwakanyanya, kumanikidzwa kwakanyanya, uye kutenderera nekukurumidza. Mvura yekuboora yakakora yeHEC inowedzera kugona kwekumisa nekutakurisa, nekukurumidza kutakura zvidimbu kuenda kumusoro wetsime uye kudzivirira njodzi yekunamira kwepombi yekuboora inokonzerwa nekuunganidzwa kwezvidimbu pasi petsime. Uyezve, HEC inoenderana zvakanaka nemvura ine mvura yegungwa, ichichengetedza kushanda kwakasimba kweviscosity kunyangwe munzvimbo dzine munyu wakawanda, zvichiita kuti ive yakakodzera zvakanyanya kumapuratifomu ekunze uye mashandiro akaomarara ekuumba.
HEC inoitawo basa rakakosha mukupedzisa nekugadzirisa masisitimu emvura. Inovandudza maitiro emvura, ichichengetedza kurasikirwa kwemvura kwakaderera uye inovandudza mhando yekeke rekusefa. Keke rekusefa remhando yepamusoro, rakatetepa, uye rakakora rinonyatsobvisa mvura yekuumbwa, richideredza kukuvara kwetangi uye richivimbisa kugadzikana kwekugadzirwa kunotevera. Pamusoro pezvo, HEC inovandudza zvakanyanya kuyerera uye kugona kwepropant suspension yemvura yekupedzisa, ichikurudzira kushanda zvakanaka uye kwakachengeteka.
Muhunyanzvi hwekupwanya, HEC yemhando yepetroleum chikamu chakakosha chemvura dzinopwanya dzinoshanda zvakanaka. Kugona kwayo kukora kunobvumira mvura inopwanya kuputika kutakura huwandu hwakawanda hwepropant mukuputika kwakadzika, zvichiita kuti igadziriswe zvakanaka. Munguva yekupwanya kuputika, tembiricha uye simba rekuchekwa kweganda zvakanyanya, asi HEC inochengetedza hunhu hwakanaka hwe viscoelastic, inoderedza kugadzika kwejecha uye inovandudza rutsigiro rwekupwanya kuputika. Kune rumwe rutivi, HEC ine hunhu hwekuora hunodzorwa; mushure mekuvakwa, inogona kuora mumamiriro ezvinhu akakodzera, ichisunungura kubva mukupwanya, ichideredza kuramba kwekudzokera shure, ichivimbisa kuyerera kwakanaka kwemafuta negasi, uye nokudaro ichiwedzera kugadzirwa. Panyaya yekuchengetedzwa kwezvakatipoteredza, HEC haina chepfu, inoora, uye haitsamwisi, zvichiita kuti ive makemikari akasvibirira uye ane hushamwari kune zvakatipoteredza. Zvichienderana nekusimbiswa kwenyika yese pasimba regirini nekukura kwakasimba, HEC haingosviki chete zvinodiwa pari zvino zvemakemikari emumunda wemafuta asiwo inobatsira makambani kuvandudza mazinga avo ekutarisira zvakatipoteredza. Kana ichienzaniswa nemapolymer echinyakare ekugadzira, HEC ine hushamwari huri nani kune zvakatipoteredza uye kuchengetedzeka kwekuchengetedza nekufambisa, zvichiita kuti pave nehurongwa hwemakemikoro hwakaderera uye hwakachengeteka mukugadzirwa kwemafuta negasi.
Kushandiswa kwemafuta emhando yepetroleumHECYakakurawo kusvika kunzvimbo dzakasiyana-siyana, kusanganisira kuwedzera kudzoreredzwa kwemafuta, kuchengetedzwa kwenzvimbo dzemvura, uye kugadzirisa mashandiro ehurongwa hwemvura inocherwa. Kuenderana kwayo muhurongwa hwakasiyana hwemvura kunoita kuti ishande pamwe chete nemakemikari akasiyana-siyana, munyu, uye zvinobatanidza kugadzira masisitimu emakemikari enzvimbo dzemafuta akawanda. Semuenzaniso, mukuburitsa mafuta akawanda, HEC inogona kuvandudza rheology yehurongwa hwemajekiseni uye kuwedzera kushanda zvakanaka kwejekiseni; mukushanda kwetsime regesi, sisitimu yekukora yeHEC inogona kutakura nekuburitsa mvura zvinobudirira, zvichivandudza kugadzirwa kwetsime regesi.
Nekukora kwayo kwakanaka, kusungirirwa kwayo, hunhu hwayo hwekugadzirisa rheological, uye hunhu hwakanaka hwezvakatipoteredza, HEC yemhando yepetroleum yave chinhu chakakosha pakubvisa mafuta negasi zvinobudirira mazuva ano. Ingave mukuchera, kuisima, kupwanya, kana kupedzisa, HEC inogona kuvandudza zvakanyanya kushanda zvakanaka uye kuchengetedzeka kwekushanda, zvichibatsira mukuvandudzwa kwakanaka uye kushandiswa kwenguva refu kwezviwanikwa zvemafuta negasi.
