Sellululose na Hydroxyl (HEC) shine ba-ionic, ruwa-ruwa mai narkewa ne daga pelullose, a zahiri abin da ke faruwa polymer wanda aka samo a jikin bangon tsirrai. Ana amfani dashi sosai a cikin masana'antu kamar man shafawa, kayan kwalliya, zane-zane, kayan zane-zane saboda ƙwararrun kayan aikinta kamar su na musamman. Koyaya, tattauna kimar PH na HEC na buƙatar mafificin fahimtar kayan aikinta, tsari, da aikace-aikace.
Fahimtar Hydroxyl Sellulose (HEC):
1. Tsarin sunadarai:
HEC ya hade ta hanyar amsawar sel tare da ethylene oxide, wanda ya haifar da gabatarwar Hydroxyl.
Matsayi na musanya (DS) yana nufin matsakaiciyar ƙimar hydroxyethyl a kowace ɓangaren glucose a cikin sarkar sel kuma yana ƙayyade kaddarorin HEC. DES DS dabi'u suna haifar da ƙara yawan ƙwarewar ruwa da ƙananan danko.
2. Properties:
Hec yana da narkar da mafita cikin ruwa da kuma siffofin share hanyoyin, wanda ya sa ya dace da aikace-aikace iri-iri suna buƙatar bayyananniyar ƙa'idodi bayyananne.
Yana nuna halayyar sauretillations, ma'ana dankalinta ya ragu a karkashin ƙarfin damuwa, yana ba da izinin aikace-aikace mai sauƙi da kulawa.
Maganin ƙwayoyin HEC yana rinjayi abubuwa masu mahimmanci kamar haɗuwa, zazzabi, ph, da kasancewar salts ko wasu ƙari.
3. Aikace-aikace:
Ana amfani da magunguna: hec ana amfani da shi azaman Thickerin da kuma magungunan magunguna iri iri kamar maganin shafawa, cream, da dakatarwar abinci.
Kayan kwalliya: Sinadarai gama gari ne a cikin samfuran kula da kayayyakin kula da na mutum ciki har da shamfu, lotions, da cream saboda cream ɗin sa.
Paints da Coftings: An ƙara HEC zuwa Paints, Coatings, da kuma adanar don sarrafa danko, inganta kayan haɓaka gudummawa, da haɓaka fim ɗin frows.
Masana'antar Abinci: A cikin kayayyakin abinci, HEC yana hidima a matsayin mai kauri, maimaitawa, da emulsifier a cikin abubuwa kamar suss, sutura, da kayayyakin kiwo.
phllularfin phlululoseth pellulose (hec):
1. Dogaro:
PH na maganin da ya ƙunshi hec na iya tasiri halayensa da aikin ta aikace-aikace daban-daban.
Gabaɗaya, HEC yana tsaye akan babban yanki na PH, yawanci tsakanin ph 2 da PH 12. Koyaya, matsanancin yanayin ph na iya shafar kaddarorin da kwanciyar hankali.
2. Sakamakon ph akan danko:
Darajojin HEC mafita na iya zama ph-dogara musamman, musamman a mawuyacin hali ko ƙananan pH.
Kusa da tsaka tsaki ph kewayon (PH 5-8), HEL mafita yawanci suna nuna girman danko.
A karancin orancin ko ƙimar pH, da sel cellulose na iya ɗaukar hydrolysis, wanda ya haifar da raguwar danko da kwanciyar hankali.
3.
A cikin tsari inda daidaitawar PH ya zama dole, ana amfani da buppers don kula da Lange na PH.
Abubuwan da aka yi kamar suna da cirrate ko fursunoni na phosphate sun dace da HEC kuma suna taimakawa ta ƙididdige ƙirar ta a cikin takamaiman kewayon PH.
4. La'akari da aikace-aikace:
Progulators dole ne la'akari da daidaituwa na HEC tare da wasu sinadarai a cikin tsari.
A wasu halaye, gyare-gyare zuwa PH na formular na iya buƙatar don inganta aikin HEC.
Sellululose na sel (HEC) polymer mai ban sha'awa tare da aikace-aikacen yaduwa a cikin masana'antu daban-daban. Duk da yake yanayin kwanciyar hankali na PH yana da ƙarfi gaba ɗaya akan kewayon da kewayon PH na iya tasiri aikinta da kwanciyar hankali. Fahimtar da distion diskirin da HEC yana da mahimmanci don tsara kayayyaki masu inganci da ingantattun samfuran, kayan kwalliya, zane-zane, masu zane-zane, da kayan zane-zane. Ta hanyar la'akari da daidaitaccen ph da kuma yin amfani da dabarun kirkirar da ya dace, Hec zai iya ci gaba da zama mai mahimmanci kayan aiki a cikin kewayon aikace-aikace dabam.
