I-Hydroxyyethyl celtulose (HEC), i-White noma elula noma ekhanyisiwe, engenasici, i-non-actic fibrous noma i-powdery eqinile, elungiselelwe yi-alkaline cellulose ne-ethylene oxide (noma i-chlorohydrin), i-genunes ancition infelle Because HEC has good properties of thickening, suspending, dispersing, emulsifying, bonding, film-forming, protecting moisture and providing protective colloids, it has been widely used in oil exploration, coatings, construction, medicine and food, textiles, papermaking and polymers. Polymerization kanye nezinye izinkambu.
Ngemuva kokuthi i-hydroxyethyl cellulose ihlangana nopende osuselwa emanzini?
Njenge-exfractant engeyona eye-ionic, i-hydroxyyethyl cellulose inezinto ezilandelayo ngokungeziwe, ukumisa, ukubopha, ukukhishwa, ukugcinwa kwamafilimu, ukugcinwa kwamanzi, ukugcinwa kwamanzi kanye nokuhlinzeka ngokuvikela ama-colloids:
I-HEC incane emanzini ashisayo noma abandayo, futhi ayinqamuleli ekushiseni okuphezulu noma ukubilisa, okwenza kube nohlu oluningi lwe-soubity kanye ne-viscosity, kanye nokugugulwa okungeyona okushisayo;
Umthamo wokugcinwa kwamanzi kabili lokho ku-methyl cellulose, futhi kunemithetho engcono yokugeleza;
Qhathanisa ne-methyl cellulose ye-methyl kanye ne-hydroxypropylm methyl celtule, amandla asabalalisayo ka-HEC yimbi kakhulu, kepha amandla avikelayo anamandla kakhulu;
Akukona-ionic futhi kungahle kube nobubanzi obuningi bakwamanye ama-polymers ancibilikayo, ama-surfactants, nosawoti. Kungumkhulu we-colloidal omkhulu omuhle kakhulu wezixazululo eziphakeme ze-electrolyte.
Ungayisebenzisa kanjani i-Hydroxyethyl cellulose?
Faka ngqo ngesikhathi sokukhiqiza - le ndlela ilula futhi ithathe isikhathi esincane:
Qala ukushukumisa ngokuqhubekayo ngejubane eliphansi bese ulungisa kancane i-hydroxyethyl cellulose ngokulinganayo kwikhambi bese uqhubeka nokuvusa kuze kube yilapho zonke izinhlayiya zimanzi. Bese ungeza okulondoloziwe kanye nezithasiselo ezahlukahlukene. Njengombala, izinsiza ezihlakazayo, i-ammonia, njll. Govuza kuze kube yilapho yonke i-hydroxyethyl cellulose ichinjiswa ngokuphelele (i-viscoxyethyls ichitshiyelwa ngokuphelele (i-viscosity yesisombululo inyuka kakhulu) ngaphambi kokungeza ezinye izakhi ezisefomula ukuze zifeze ukusabela.
Ifakwe notshwala bamama
Kungukulungiselela utshwala bomama onolohlo oluphakeme kuqala, bese ulufaka kumkhiqizo. Inzuzo yale ndlela ukuthi inokuguquguquka okukhulu futhi kungangezwa ngqo kumkhiqizo oqediwe, kepha kufanele kugcinwe kahle. Izinyathelo zale ndlela ziyefana nezinyathelo eziningi ngendlela 1; Umehluko ukuthi asikho isidingo se-agaritator ephezulu, futhi ezinye izikhuthazi ezinamandla anele okugcina i-hydroxyethylllurl purcile efanelwe ngokulinganayo kusatshalaliswa ngesisombululo esingasebenza, futhi qhubekani nivusa kuze kube yisixazululo esibonakalayo. Kodwa-ke, kufanele kuqashelwe ukuthi umenzeli we-antifungal kumele angezwe kuphuzo lotshwala masinyane.
Izeluleko Zomusa:
Kusukela i-Hydroxyyethyls ephethwe yi-PerdroxyYethyl i-powdery noma i-fibrous swolid, lapho ulungiselela i-hydroxyethyyl cellulose mama makeome, ngikukhumbuze ukuthi unake amaphuzu alandelayo:
Ngaphambi nangemva kokungeza i-hydroxyethyl cellulose, kufanele igcinwe ivuselelwa kuze kube yilapho ikhambi lisobala futhi licacile;
Kufanele ibonakale emgqonyeni wokuxuba kancane, futhi ungaxhumeki ngokuqondile izigaxa noma ama-sproids kanye ne-hydroxyethyl cellulose emgqonyeni wokuxuba;
Izinga lokushisa lamanzi nenani le-PH lamanzi linobudlelwano obukhulu nokuchithwa kweHydroxyethyl cellulose, ngakho-ke kufanele kukhokhwe kuwo;
Ungangezi ezinye izinto ze-alkaline engxube ngaphambi kwe-hydroxyethyl cellulose powder ifakwe emanzini. Ukuphakamisa Inani le-PH ngemuva kokuthambisa kuzosiza ukuncibilikisa;
Ngokwazi, engeza i-antifungal ejenti kusengaphambili;
Lapho usebenzisa i-helcoxyyethylyls ephakeme, ukugcwaliseka kotshwala mama akufanele kube ngaphezulu kuka-2,5-3% (ngesisindo), uma kungenjalo kunzima ukusingatha.
