Yini i-Ultra-High Viscosity HEC?

I-Ultra-high viscosisisisision hydroxyyethyl celtulose (HEC) yi-poly-soluble polymer compact eyakhiwa ukusheshisa kwe-cellulose. Ngenxa yokuvunywa kwayo okumangalisayo nokuqina, i-HEC isetshenziswa kabanzi emikhakheni eminingi efana nezimonyo, amakhamishini, ukwakhiwa kanye nokukhishwa uwoyela.

(1), Indlela ye-HEC nendlela yokulungiselela

1.1 UHLELO
I-HEC iyinto etholwa etholwa etholakala ekwelashweni kwamakhemikhali kwe-cellulose yemvelo. Iyunithi yayo eyisisekelo yesakhiwo yi-β-d-glucose, exhunywe ngamabhondi we-β-1,4 glycosidic. I-Hydroxyl Group (-OH) e-cellulose ithathelwa indawo yi-ethylene oxide (eo) noma enye i-ejenti etheriness, ngaleyo ndlela ingenisa iqembu le-ethoxy (-ch2ch2oh) ukwakha i-hydroxyethyllll. I-Ultra-High-High Mocutity Hec inesisindo esiphakeme samangqamuzana, imvamisa phakathi kwezigidi namashumi ezigidi, okuvumela ukuthi ibonise ukubonakala okukhulu kakhulu emanzini.

1.2 Indlela Yokulungiselela
Ukulungiswa kwe-HEC kuhlukaniswe ngezinyathelo ezimbili: ukwehla kwe-cellulose nokuphendula okuthe xaxa.

Ukwehla kwe-cellulose: I-cellulose yemvelo (njengokotini, ipulpiti yezinkuni, njll.) Iphathwe amaketanga ama-alkali ukuwelula futhi ahlukanise amaketanga ama-cellulose ama-cellulose yokuphendula okulandelayo kwetherali.

Ukusabela kwe-Etherification: Ngaphansi kwezimo ze-alkaliwe, isellose esenziwe njenge-collulose ehleliwe yenziwa nge-oxide ye-ethylene oxide noma amanye ama-ejenti athembela ukwethula amaqembu e-hydroxyethyyl. Inqubo yokusabela iyathinteka yizinto ezifana nokushisa, isikhathi, kanye nokuthembela ukugxilisa i-ejenti, kanye ne-HEC eneziqu ezahlukahlukene zokufakwa esikhundleni (DS) kanye nokufakwa esikhundleni (MS) ukuqunjelwa. I-Ultra-High-High Chiskuthaka ngokuvamile idinga isisindo esiphakeme se-molecular kanye nezinga elifanele lokufaka esikhundleni sokuqinisekisa izici zalo zokuvuselela amanzi emanzini.

(2) Izici ze-HEC

2.1 I-Solubity
UHek uyancibilika emanzi abandayo nawashisayo, akha isixazululo esibonakalayo esibonakalayo noma esishisayo. Izinga lokuchithwa lithintwa yizici ezinjengesisindo se-molecular, degree of substiture, kanye nokushisa kwesisombululo. I-Ultra-High Movisity Hec ine-soubity ephansi emanzini futhi idinga ukushukumisela isikhathi eside ukuze kuncibilike ngokuphelele.

-Nenyelekile
I-Viscosity ye-Ultra-High Viscosity Hec ephakeme yisici sayo esiphawuleka kakhulu. I-viscosity yayo ivame ukusukela ezinkulungwaneni eziningana kuya kumashumi ezinkulungwane zemimoya (ama-MPA S), kuya ngokuhlushwa, izinga lokushisa, kanye nesixazululo sekhambi. I-viscosity ye-HEC ayigcini ngokuncika kwesisindo se-molecular, kepha futhi ihlobene kakhulu nezinga lokufaka esikhundleni sesakhiwo samangqamuzana.

2.3 Ukuqina
I-HEC inokuqina okuhle kuma-acid, ama-alkali kanye nama-solvents amaningi we-organic futhi awonakaliswa kalula. Ngaphezu kwalokho, izixazululo ze-HEC zinokuqina okuhle kwesitoreji futhi zingagcina ukubonwa kwazo nezinye izakhiwo zenyama nangamakhemikhali isikhathi eside.

2.4 Ukuvumelana Ukuvumelana
I-HEC iyahambisana namakhemikhali ahlukahlukene, kufaka phakathi ama-surfactants, usawoti kanye namanye ama-polymers ancibilikayo. Ukuhambisana kwayo okuhle kusenza sikwazi ukugcina ukusebenza okuzinzile ezinhlelweni eziwubumba eziwubumba.

(3) Ukusetshenziswa kwe-HEC

3.1 Izimonyo nemikhiqizo yokunakekelwa komuntu siqu
Kwezimonyo, i-HEC isetshenziswa kabanzi njengomuntu omkhulu, i-stabilizer kanye ne-ejenti eyakha ifilimu. I-Ultra-High Viscosity Hec inganikeza ukuthinta okuhle nokuqina okuhlala isikhathi eside futhi isetshenziswa kakhulu kwimikhiqizo efana ne-lotion, ama-shampoos, kanye nezimo.

3.2 Imboni Yezemithi
Njenge-Exepieint ye-Phamisi, i-HEC ivame ukusetshenziselwa ukulungiswa kwamathebulethi okukhishwa okuqhubekayo, ama-gels namanye amalungiselelo emithi. Impahla yayo ephezulu ye-viscosity ingalawula isilinganiso sokukhishwa kwezidakamizwa futhi ithuthukise ukungatholakali kwesidakamizwa.

3.3 Izinto zokwakha
Embonini yezokwakha, i-HEC isetshenziswa njenge-persener kanye ne-ejenti yokugcina amanzi yezinto zokwenziwa kosimende ne-gypsum. I-viscosity yayo ephezulu kanye nokugcinwa kwamanzi okuhle kusiza ukuthuthukisa ukusebenza kokwakha futhi kuvikele izinto zomiswe ngaphandle nokudambisa.

3.4 Ukukhishwa kwamafutha
Embonini kaPetroleum, i-HEC isetshenziswa ekuvutheni uketshezi kanye nokuphupha uketshezi njengoMkhulu nodonse. I-Ultra-High-High Chec ingathuthukisa umthamo wokumiswa kanye nomthamo othwala isihlabathi, ukuthuthukisa imiphumela yokushayela nokuphupha kwemisebenzi.

(4) Amathemba okuthuthuka kwe-HEC

Ngokuthuthuka kobuchwepheshe kanye nezinguquko ekufunweni kwemakethe, ubukhulu besicelo se-HEC siyaqhubeka ukwandisa. Izinkomba zokuthuthukisa ikusasa zifaka:

4.1 Ukuthuthukiswa kwe-hec yokusebenza okuphezulu
Ngokwandisa inqubo yokukhiqiza kanye nezilinganiso ezibonakalayo eziluhlaza, i-HEC enokubonakala okuphezulu, i-solubelity engcono nokuqina kungakhiwa ukuze kuhlangatshezwane nezimo zohlelo lokusebenza eziphakeme.

4.2 Ukuvikelwa Kwezemvelo Nentuthuko Esimeme
Thuthukisa izinqubo zokukhiqiza ezinobungani bemvelo kanye nezinto zokwakha ezivuthiwe, ukunciphisa ukusetshenziswa kwamandla nokukhishwa kwemfucuza ngesikhathi sokukhiqiza, futhi kuthuthukise ukuqina kwe-HEC.

Ukunwetshwa kwama-4.3 amasimu wohlelo lokusebenza amasha
Hlola amandla okufaka isicelo se-HEC emikhakheni yezinto ezintsha, imboni yokudla kanye nobunjiniyela bezemvelo ukukhuthaza uhlelo lokusebenza kuzimboni eziningi.

I-Viscosity ye-Ultra-High Izici zayo ezihlukile ze-viscosity kanye nokuqina okuhle kwamakhemikhali kwenza kube nendima ebalulekile ezimbonini ezahlukahlukene. Ngokuthuthuka kobuchwepheshe kanye nokwanda kwezinkambu zohlelo lokusebenza, amathemba emakethe ka-HEC azoba abanzi.
