Yini inani le-hydroxyethyl celtulose elingeziwe?

IHydroxYethyl Cellulose (HEC) i-polymer engenawo amanzi e-ionic asetshenziswa kabanzi kwezimonyo, ukumboza, izindwangu zokwakha, amakhemikhali omakhemisi kanye nemithi njenge-ejenti ye-ejenti kanye ne-ejenti ye-ejenti. Inomphumela omuhle wokuqina, ukumelana nosawoti, ukumelana no-alkali kanye ne-biodegrade enhle. Kuhlelo lwangempela, inani le-hydroxyethyl celtulose elingeziwe lizohluka ngokuya ngenkambu yesicelo, sebenzisa imvelo kanye nokusebenza okudingekayo.

Emkhakheni wezimonyo, i-hydroxyethyl cellulose ivame ukusetshenziswa njengomuntu omkhulu kanye ne-stabilizer. Isibonelo, emikhiqizweni efana ne-lotions, ama-gels, kanye nokuhlanza kobuso, i-hydroxyyethyl celtule Kulokhu, inani le-hydroxyethylllose elingeziwe livame phakathi kuka-0,1% no-1%, futhi inani elithile lidinga ukulungiswa ngokuya ngefomula ethile nezidingo zomkhiqizo. Uma ukuhlakanipha okuphezulu noma ukusebenza okungcono kokumiswa okudingekayo, inani elingeziwe lingakhuphuka ngendlela efanele; Uma kudingeka ukubonakala okuphansi, inani elingeziwe lizoncishiswa.

Ezintweni zokwakha, i-hydroxyyethyl cellulose ivame ukusetshenziswa emikhiqizweni efana nosimende, izinto ezisekelwa yi-gypsum, i-putty powder kanye nokumboza ukuqina, ukugcina amanzi, ukwenza ngcono ukusebenza futhi kuthuthukise ukusebenziseka futhi kuthuthukise ukukhiqizwa kwezinto ezibonakalayo. Kuzo ezifakiwe, inani le-hydroxyethyl celtulose elengeziwe livame phakathi kuka-0.2% no-0.5%. Leli nani eliphansi lanele ukuthuthukisa ukusebenza kahle kokusebenza kwezinto ezisebenzayo ngaphandle kokukhulisa ngokweqile izindleko zokwaziswa noma ezithinta ukusebenza kokugcina kwezinto ezibonakalayo. Kuzinhlelo zokusebenza ezisebenzayo, inani elithile elengeziwe lidinga ukulungiswa ngokuya ngokwakheka kwezinto, ukusebenza okudingekayo kwezokwakha kanye nezimo zemvelo.

Emakhemikhali e-oilfield, i-hydroxyyethyl cellulose isetshenziswa njengomuntu omkhulu kanye noketshezi lokunciphisa uketshezi lokumba, ukuqeda uketshezi oluphoqelela ngempumelelo i-viscosity, uzinze ngempumelelo i-viscosity ye-liquid. Kule nkambu, inani le-hydroxyethyl celtulose elengeziwe livame phakathi kuka-0.5% no-1.5%. Inani langempela elingeziwe lizothinteka ngezimo ze-Downhole (ezinjengokushisa, ingcindezi, izimo zezwe, njll.), Ngakho-ke kudinga ukulungiswa ngokuya ngendawo ethile yokwakha kanye nezidingo.

Embonini yezambane, inani lokungezwa le-hydroxyethyl celtulose livame phakathi kuka-0,1% no-0.5%, kuya ngohlobo lokukhomba kanye nokuvunywa okudingekayo. Ezimbozweni ezisuselwa emanzini, i-hydroxyyethyl cellulose ayihlinzeki kuphela umphumela wokuqina, kodwa futhi ithuthukisa i-thixotropy ye-coating (ie, impahla yokubonakala inciphisa lapho ivuselelwa futhi ilulama lapho imayo futhi ilwa nokudlalwa kwezindawo zokufunda. Ku-powder coathings, i-hydroxyyethyl celtule

Inani le-hydroxyethyl celtulose elifakiwe kuncike ezintweni ezifana nezidingo zalo ezisebenzayo kuhlelo lokusebenza oluthile, i-viscosity edingekayo, ukusebenza kwezindleko. Lapho uklama ifomula, kuvame ukudingekile ukuthola inani elifanele lokungezwa ngokusebenzisa izivivinyo kanye nesipiliyoni sokufeza ukusebenza komkhiqizo okulindelekile. Kungakhathalekile ukuthi injani insimu, inani elifanelekile lesengezo alikwazi ukuqinisekisa ukusebenza okuhle komkhiqizo, kepha futhi nokulawula izindleko futhi kuthuthukise ukusebenza kahle kokukhiqiza. Ekusebenzeni kwangempela, ochwepheshe bazokwenza kahle inani lokungeza elisuselwa kwimiphumela yokuhlola kanye nezidingo ezithile zokuqinisekisa ukuthi ikhwalithi nokusebenza komkhiqizo wokugcina kuhlangabezana namazinga alindelwe.
