Ukuqhathaniswa kwe-HEC nabanye abakhulu

Abakhulu basetshenziswa kabanzi ekukhiqizeni kwezimboni, okubandakanya ukugqoka, izinto zokwakha, izimonyo, ukudla nomuthi. IHydroxYethyl Cellulose (HEC) ingumkhulu obalulekile odonsele ukunakwa ngezakhiwo zayo ezihlukile nohlelo lokusebenza olubanzi.

1. Ukwakheka kanye nomthombo
I-HEC iyi-ether ye-cellulose eyenziwe ngokuphendula i-cellulose yemvelo nge-oxide ye-ethylene oxide. I-polymer engenawo amanzi angenawo ama-ionic anokuqina okuhle kwamakhemikhali. Ngokuphambene, abanye abakhulu banemithombo ehlukahlukene, kufaka phakathi okulandelayo:

Abakhulu be-Natural PolysacCharide: Njenge-Xanthan Gum kanye neGum Gum, laba bakhulu bathathwa ezitshalweni zemvelo noma ukuvutshelwa kwe-microbial futhi bavikeleke kakhulu imvelo.

Okwenziwanisi Abakhulu: Njengama-acrylic acid polymers (carbomer), asuselwa ku-petrochemicals, anokusebenza okuzinzile, kodwa i-biodegrade engeyinhle.

Ama-Protein Friseners: njenge-gelatin, ikakhulukazi athathwe ezicutshini zezilwane futhi alungele ukudla nomuthi.
I-HEC inokuvikelwa kwemvelo kwe-cellulose yemvelo kanye nokusebenza okuhle kakhulu kokuguqulwa kwamakhemikhali ekwakhiweni, ekutholeni ibhalansi phakathi kobungane bezemvelo nokusebenza okuhlukahlukene.

2. Ukuqina kokuqina
I-HEC inezimpawu ezilandelayo ekusebenzeni kokuqina:

I-Solubinity: I-HEC ingachithwa emanzini abandayo namanzi ashisayo ukwakha isixazululo esibonakalayo se-viscous ngesilinganiso sokuchithwa okusheshayo. I-Xanthan Gum imvamisa idinga amandla we-shear ukusiza ukuchitheka, futhi isixazululo singase sibe ne-turbidity ethile.
Ububanzi bokulungiswa kwe-viscosity obubanzi Ngokuphambene nalokho, uhla lwe-viscosity lokulungiswa kweGuar Gum luncane. Yize i-acrylic acid polymer inomphumela omuhle kakhulu, iyazwela kakhulu ngenani le-PH.
Ukusebenza kwe-Shear Switning Ukusebenza: I-HEC inokuziphatha okunciphisayo okunciphisayo futhi ilungele izikhathi lapho i-visputy ethile yehlelekile idinga ukugcinwa khona. I-Xanthan Gum inobuqili be-pseudoplasticity ebalulekile futhi ilungele ukusetshenziswa kwezimbozo nama-emulsions okudla.

3. Ukuqina kwamakhemikhali
I-HEC inokuqina okuhle ebangeni elibanzi le-PH (2-12), futhi imelana nokushisa okuphezulu nosawoti, futhi ilungele izinhlelo zokusebenza ezinhlelweni eziqukethe usawoti noma ezindaweni eziphakeme zokushisa. Ngokuqhathanisa:

I-Xanthan Gum inokumelana nosawoti okungcono kune-HEC, kepha iyonakala kalula ngaphansi kwezimo ezinamandla ze-acid kanye ne-alkali.
Ama-acrylic acrymers azwela i-acid ne-alkali, futhi athambekele ekwehlulekeni ngaphansi kwezimo zokuhlushwa usawoti okuphezulu.
Ukuqina kwamakhemikhali kwabakhudlwana be-polysaccharide bemvelo ngaphansi kwezimo eziphakeme zokushisa kanye nezimo ze-oxidative imvamisa akukuhle njenge-hec.

4. Umehluko ezindaweni zohlelo lokusebenza
I-Coatings nezinto zokwakha: I-HEC ivame ukusetshenziswa egqokeni elisekelwe emanzini, ama-powders ama-putty kanye nodaka, enikeza imiphumela emihle yokuqina kanye nezindawo zokugcina amanzi. I-Xanthan Gum isetshenziswa kakhulu ezintweni ezingenamanzi, ikakhulukazi ngenxa yezakhiwo zayo ezinciphayo.
Izimonyo nemikhiqizo yamakhemikhali yansuku zonke: I-HEC inganikeza ngesikhumba esibushelelezi futhi umphumela omuhle wokuqina, futhi isetshenziswa kabanzi kubahlanza bobuso kanye ne-lotions. Ama-acrylic ama-polymers anenzuzo emikhiqizweni ye-gel ngenxa yokubonakala kwawo okuphezulu kanye nekhono eliqinile lokuqina.
Ukudla nomuthi: I-Xanthan Gum kanye neGuar gum kusetshenziswa kakhulu ekudleni nasezokwelapha ngenxa yemvelaphi yabo yemvelo nokuba khona okuhle. Yize i-HEC ingasetshenziswa futhi kumalungiselelo okukhishwa kwezidakamizwa, inezicelo ezimbalwa zebanga lokudla.

I-5. Imvelo Nezindleko
I-HEC inobungani bemvelo futhi iyadinwa ngoba ikhiqizwa ngokususelwa ku-cellulose yemvelo. Inqubo yokukhiqiza yama-acrymers anomthelela omkhulu emvelweni futhi kunzima ukungcola ngemuva kokulahlwa. Yize uXanthan Gum kanye neGum Gum banobungane bemvelo, amanani abo avame ukuphakama kune-hec, ikakhulukazi yemikhiqizo eguquliwe kuzinhlelo ezikhethekile.

Njengomkhulu onokusebenza okulinganiselayo, i-HEC inezinzuzo ezihlukile emikhakheni eminingi. Qhathanisa ne-xanthan gum ne-guar gum, i-HEC iyancintisana ngokuqina kwamakhemikhali kanye nokusebenza kwezindleko; Uma kuqhathaniswa nama-acrylic acrymers, i-HEC inobungane kakhulu imvelo futhi inokuguquguquka okubanzi. Ekukhetheni kwangempela, izici ezinjengokusebenza kokuqina, ukuqina kwamakhemikhali nezindleko kufanele kubhekwe ngokunjalo ngokwezidingo ezithile zohlelo lokusebenza ukufeza umphumela omuhle kakhulu nenani.
