IHydroxyethyl cellulose (HEC) iyi-fibrous emhlophe noma ekhanyayo, engenaphunga, engenabuthi noma eqinile eyimpuphu, elungiswa ngokusabela kwe-etherification ye-alkaline cellulose ne-ethylene oxide (noma i-chlorohydrin).I-Nonionic soluble cellulose ethers.Njengoba i-HEC inezakhiwo ezinhle zokuqina, ukumisa, ukuhlakazeka, ukuhlanganisa, ukubopha, ukwenza ifilimu, ukuvikela umswakama nokuhlinzeka nge-colloid evikelayo, iye yasetshenziswa kabanzi ekuhloleni amafutha, ukugqoka, ukwakhiwa, imithi, ukudla, izindwangu, ukwenza iphepha kanye ne-polymerization. nezinye izinkambu.Isilinganiso se-40 se-mesh sieving ≥ 99%;
Ukubukeka: okumhlophe kuya kokuphuzi okukhanyayo okuyi-fibrous noma okuqinile okuyimpuphu, okungewona ubuthi, akunambitheki, kuncibilika emanzini.Ayincibiliki kuzincibilikisi ezivamile zemvelo.
I-Hydroxyethyl celluloseukuqina
I-viscosity ishintsha kancane kububanzi bevelu engu-PH 2-12, kodwa i-viscosity yehla ngale kwalolu bubanzi.Inezici zokuqina, ukumisa, ukubopha, i-emulsifying, ukusabalalisa, ukugcina umswakama nokuvikela i-colloid.Izixazululo kumabanga ahlukene we-viscosity zingalungiswa.Ayizinzi ngaphansi kwezinga lokushisa elivamile nokucindezela, gwema umswakama, ukushisa, nezinga lokushisa eliphezulu, futhi ibe nokuncibilika okuhle kakhulu kukasawoti kuma-dielectrics, futhi isisombululo sawo esinamanzi sivumela ukugcwala okuphezulu kukasawoti ukuthi uhlale uzinzile.
Izakhiwo ezibalulekile:
Njenge-surfactant engeyona i-ionic, i-hydroxyethyl cellulose inalezi zakhiwo ezilandelayo ngaphezu kokuqina, ukumisa okwesikhashana, ukubopha, ukuntanta, ukwenza ifilimu, ukuhlakazeka, ukugcinwa kwamanzi kanye nokuhlinzeka nge-colloid evikelayo:
1. I-HEC iyancibilika emanzini ashisayo noma emanzini abandayo, futhi ayidli ngokushisa okuphezulu noma ukubilisa, ukuze ibe nezinhlobonhlobo zezimpawu ze-solubility kanye ne-viscosity, kanye ne-gelation engashisi;
2. Ayiyona i-ionic futhi ingahlala nohlu olubanzi lwama-polymers ancibilika emanzini, ama-surfactants, nosawoti.Kuyinto enhle kakhulu ye-colloidal thickener yezixazululo eziphezulu ze-electrolyte;
3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono.
4. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa ikhono le-colloid lokuvikela liqine kakhulu.
Inkambu yohlelo lokusebenza

Isetshenziswa njenge-polymeric dispersant ukuze kusetshenziswe i-petroleum water-based gel fracturing fluid, i-polyvinyl chloride ne-polystyrene.Ingasetshenziswa futhi njenge-emulsion thickener embonini yepende, i-samente anticoagulant kanye ne-ejenti yokugcina umswakama embonini yezokwakha, i-glazing agent kanye ne-toothpaste adhesive embonini ye-ceramic.Ibuye isetshenziswe kabanzi emikhakheni yezimboni njengokuphrinta nokudaya, izindwangu, ukwenza amaphepha, imithi, inhlanzeko, ukudla, ugwayi nezibulala-zinambuzane.
Ukusebenza Komkhiqizo
1. I-HEC iyancibilika emanzini ashisayo noma emanzini abandayo, futhi ayidli ngokushisa okuphezulu noma ukubilisa, ukuze ibe nezinhlobonhlobo zezimpawu ze-solubility kanye ne-viscosity, kanye ne-gelation engashisi;
2. Ayiyona i-ionic futhi ingahlala namanye ama-polymers ancibilika emanzini, ama-surfactants nosawoti ebangeni elibanzi.Kuyi-thickener ye-colloidal enhle kakhulu yezixazululo eziqukethe ama-dielectrics aphezulu;
3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono;
4. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa ikhono le-colloid lokuvikela liqine kakhulu.
Isetshenziswa kanjaniI-HEC?
kwengezwe ngokuqondile ngesikhathi sokukhiqiza
1. Faka amanzi ahlanzekile ebhakedeni elikhulu elifakwe umxube wokugunda okuphezulu.
2. Qala ukunyakazisa ngokuqhubekayo ngesivinini esiphansi bese uhlunga kancane kancane i-hydroxyethyl cellulose esixazululweni ngokulinganayo.
3. Qhubeka ugqugquzela kuze kube yilapho zonke izinhlayiya sezicwile.
4. Bese wengeza i-antifungal agent, izithasiselo ze-alkaline ezifana nezingulube, izinsiza ezihlakazayo, amanzi e-ammonia.
5. Hlanganisa kuze kube yilapho yonke i-cellulose ye-hydroxyethyl ichitheka ngokuphelele (i-viscosity yesisombululo ikhula kakhulu) ngaphambi kokwengeza ezinye izingxenye kufomula, futhi ugaye kuze kube umkhiqizo ophelile.
