IHydroxyethylcellulose (HEC) iyinhlanganisela ye-polymer encibilika emanzini esetshenziswa kabanzi esetshenziswa kakhulu emikhiqizweni yokunakekelwa komuntu siqu efana nejeli yeshawa nensipho ewuketshezi. Umsebenzi wayo oyinhloko ukusebenza njenge-thickener, stabilizer kanye ne-emulsifier ukuthuthukisa izakhiwo ezingokomzimba nolwazi lomsebenzisi lomkhiqizo.
(1). Ukusetshenziswa kwe-HEC kujeli yokugeza
Ijeli yeshawa wumkhiqizo wokunakekela umuntu osetshenziswa kabanzi umsebenzi wawo oyinhloko uwukuhlanza isikhumba. I-HEC idlala indima ebalulekile kujeli yokugeza, futhi ukusetshenziswa kwayo okuqondile kungokulandelayo:
1.1 Ukuqina komphumela
I-HEC ingakhuphula ngempumelelo i-viscosity yejeli yokugeza, inikeze ukuvumelana okuhle nokugeleza kwamanzi. Lokhu akusizi nje ukuthuthukisa ukuthungwa komkhiqizo, kodwa futhi kuvimbela umkhiqizo ukuthi ungahluli noma uzinze ebhodleleni. Ngokulawula inani le-HEC elingeziwe, i-viscosity yejeli yokugeza ingalungiswa ukuze ihlangabezane nezidingo zabathengi abahlukene.
1.2 Umphumela wokuzinzisa
Njenge-stabilizer, i-HEC ingavimbela izithako ezisebenzayo kujeli yokugeza ekuhlukaniseni noma ekuxazululeni. Ingenza ingxube efanayo phakathi kwesigaba samanzi kanye nesigaba samafutha, iqinisekise ukuthi umkhiqizo uhlala uzinzile ngesikhathi sokugcinwa nokusetshenziswa. Ukuba khona kwe-HEC kubaluleke kakhulu kuma-gel okugeza aqukethe amafutha abalulekile noma ezinye izithako ezingancibiliki.
1.3 Umphumela wokuthambisa
I-HEC inezinto ezinhle zokuthambisa futhi ingakha ifilimu emanzisa ebusweni besikhumba ukuvimbela ukulahlekelwa kwamanzi. Lokhu kusiza ukugcina isikhumba simanzi futhi kwenza abasebenzisi bazizwe benethezekile futhi beswakama ngemva kokusebenzisa ijeli yokugeza. Uma isetshenziswa ihlanganiswe namanye ama-moisturizers, i-HEC ingathuthukisa umphumela wokuthambisa womkhiqizo.
(2). Ukusetshenziswa kwe-HEC kunsipho ewuketshezi
Insipho ewuketshezi ingomunye umkhiqizo ojwayelekile wokunakekela umuntu, osetshenziselwa ukuhlanza izandla nomzimba. Ukusetshenziswa kwe-HEC ensipho ewuketshezi kufana nejeli yokugeza, kodwa futhi inezici zayo ezihlukile:
2.1 Ukwenza ngcono ukuthungwa kwegwebu
I-HEC ingathuthukisa ukuthungwa kwegwebu lensipho ewuketshezi, iyenze ibe ntekenteke futhi ihlale isikhathi eside. Nakuba i-HEC ngokwayo ingeyona i-ejenti enegwebu, ingasiza ekugcineni ukuzinza kwegwebu ngokwandisa i-viscosity nokuzinza koketshezi. Lokhu kwenza insipho ewuketshezi inothe ngegwebu futhi kulula ukuyihlanza uma isetshenziswa.
2.2 Ukulawula uketshezi
Insipho ewuketshezi ivamise ukupakishwa emabhodleleni epompo, futhi uketshezi lungenye yezici zayo ezibalulekile. Umthelela wokujiya we-HEC ungasiza ekulungiseni uketshezi lwensipho ewuketshezi, iyenze ingabi mncane kakhulu noma iminyene kakhulu lapho ikhishwa, okwenza kube lula kubasebenzisi ukuyisebenzisa. I-fluidity efanele ingagwema nokumosha ngokweqile futhi iqinisekise ukuthi umthamo osetshenziswa isikhathi ngasinye umaphakathi.
2.3 Ukunikeza umuzwa wokugcoba
Phakathi nenqubo yokugeza izandla, i-HEC inganikeza umuzwa othile wokugcoba futhi inciphise ukungqubuzana kwesikhumba. Lokhu kubaluleke kakhulu kubasebenzisi abavame ukusebenzisa insipho ewuketshezi, njengoba inganciphisa ingozi yesikhumba esomile nesimangelengele. Ikakhulukazi ezinsipho eziwuketshezi eziqukethe izithako ezilwa namagciwane, umphumela wokugcoba we-HEC ungadambisa ukungakhululeki kwesikhumba okubangelwa izithako zokuhlanza ezeqile.
(3). Izinyathelo zokuphepha zokusetshenziswa
Nakuba i-HEC inezinzuzo eziningi emikhiqizweni yokunakekelwa komuntu siqu, kukhona nezinye izinto okufanele uziqaphele lapho uyisebenzisa:
3.1 Ukwengezwa kwenani lokulawula
Inani le-HEC elengeziwe lidinga ukulungiswa ngokuvumelana nezidingo ezithile zomkhiqizo. I-HEC eningi kakhulu ingase yenze umkhiqizo ube ne-viscous kakhulu futhi kuthinte isipiliyoni somsebenzisi; I-HEC encane kakhulu ingase ingawufezi umphumela ofanele wokujiya. Ngokuvamile, inani le-HEC elisetshenzisiwe liphakathi kuka-0.5% no-2%, futhi kufanele lilungiswe ngokuvumelana nefomula ethile kanye nomphumela olindelekile.
3.2 Izinkinga zokuxazululeka
I-HEC idinga ukuncibilika ngokuphelele emanzini ukuze isebenze. Phakathi nenqubo yokukhiqiza, i-HEC ivame ukuxutshwa nezinye izithako ngaphambi kokwengeza amanzi kancane kancane ukuvimbela i-caking noma i-agglomeration. Ngesikhathi esifanayo, ukugqugquzela okwanele kuyadingeka ngesikhathi sokuchithwa ukuze kuqinisekiswe ukuthi i-HEC ihlakazeke ngokulinganayo esixazululweni.
3.3 Ukuhambisana nezinye izithako
I-HEC inokuqina okuhlukile kumanani e-pH ahlukene, ngakho-ke ukuhambisana nezinye izithako kudinga ukucatshangelwa lapho kwakhiwa ifomula. Ama-surfactants athile noma izincibilikisi zingathinta ukusebenza kwe-HEC futhi zibangele nokwehluleka komkhiqizo. Ngakho-ke, lapho wethula izithako ezintsha kufomula, ukuhlolwa kokuqina okwanele kufanele kwenziwe.
Ukusetshenziswa kwe-hydroxyethyl cellulose kujeli yokugeza kanye nensipho ewuketshezi kunezinzuzo ezibalulekile. Akuthuthukisi nje kuphela izici ezibonakalayo zomkhiqizo, kodwa futhi kuthuthukisa isipiliyoni somsebenzisi. Kodwa-ke, uma usebenzisa i-HEC, ukunakwa kufanele kukhokhwe ekulawuleni inani lokwengeza, izinkinga ze-solubility, nokuhambisana nezinye izithako ukuze kuqinisekiswe ukuphepha nokusebenza komkhiqizo. Ngokuthuthuka okuqhubekayo kobuchwepheshe, amathuba okusebenzisa i-HEC emikhiqizweni yokunakekelwa komuntu siqu azoba banzi.
