I-HEC I-Hydroxyethyl Cellulose, ikhompawundi ebalulekileyo yeekhemikhali efumana ukusetyenziswa ngokubanzi kumashishini ahlukeneyo, ngakumbi kwindawo yeemveliso zokhathalelo lomntu, amayeza, kunye nezinto zokwakha. Ngeempawu zayo ezizodwa kunye nokusetyenziswa kwezinto ezininzi, i-HEC idlala indima ebalulekileyo ekwandiseni umgangatho kunye nokusebenza kweemveliso ezininzi.
Kwisiseko sayo, i-HEC i-non-ionic, i-polymer e-soluble yamanzi ephuma kwi-cellulose ngokuguqulwa kweekhemikhali. I-Cellulose, i-polymer yendalo efunyenwe kwiindonga zeeseli zesityalo, ifumana impendulo elawulwayo kunye ne-ethylene oxide, ekhokelela ekuqalisweni kwamaqela e-hydroxyethyl kwi-backbone ye-cellulose. Olu hlengahlengiso lunika ukunyibilika kwamanzi kunye nezinye izinyibilikisi zepolar kwisiphumo se-HEC yepolymer, iyenza ibe yinto eguquguqukayo kakhulu kwizicelo ezahlukeneyo.
Olunye lweempawu eziphambili ze-HEC kukukwazi ukujiya. Ngenxa yobume bayo beemolekyuli kunye nokusebenzisana kunye neemolekyuli zamanzi, i-HEC inokunyusa kakhulu i-viscosity yezisombululo zamanzi kwiindawo eziphantsi kakhulu. Le propathi iyenza ibe sisithako esiphambili ekwenziweni kweemveliso ezininzi zokhathalelo lomntu ezinje ngeeshampu, iiconditioners, lotions, kunye necreams. Ngokulungelelanisa ukugxininiswa kwe-HEC, abavelisi banokulawula ukuhambelana kunye nokuthungwa kwezi mveliso, ukuqinisekisa ukusebenza kakuhle kunye namava omsebenzisi.
Ukongeza kwiipropathi zayo ezityebileyo, i-HEC ikwasebenza njenge-rheology modifier esebenzayo. I-Rheology ibhekisa kuphononongo lokuhamba kunye nokuguqulwa kwezinto, kwaye izilungiso ze-rheology ezifana ne-HEC zinokuchaphazela i-viscosity, i-shear thinning behavior, kunye nezinye iimpawu zokuhamba kwamanzi. Kwipeyinti kunye neengqungquthela zokugqoka, umzekelo, i-HEC inceda ukufezekisa iipropati ezifunwayo zesicelo, ezifana ne-brushability, ukumelana ne-spatter, kunye nokwakhiwa kwefilimu.
Ngaphezu koko, i-HEC isebenza njenge-stabilizer kunye ne-arhente yokumisa kwiifom ezininzi. Ikhono layo lokwenza isakhiwo sothungelwano oluzinzile kwizisombululo kunceda ukuthintela ukuhlalisa okanye ukuhlukana kwesigaba samaqhekeza aqinile okanye amaconsi e-emulsified. Oku kwenza i-HEC ixabiseke kakhulu kwimveliso yokumiswa kwamachiza, i-ceramic glazes, kunye ne-drilling fluids, apho ukusabalalisa okufanayo kunye nokuzinza kwamacandelo kubalulekile.
Umthamo wokugcina amanzi we-HEC ngomnye umba obalulekileyo onegalelo ekusebenzeni kwayo kwizicelo ezahlukeneyo. Ngokuthabatha kunye nokugcina iamolekyu zamanzi, i-HEC inokwandisa ixesha lokuhamba kunye nokukhululwa kwezithako ezisebenzayo ekuqulunqweni, ukuphucula ukusebenza kwazo kunye nokusebenza ngexesha. Olu phawu lunenzuzo ngokukhethekileyo kushishino lokwakha, apho i-HEC iqeshwe kwizinto ze-cementitious, i-adhesives tile, kunye ne-grouts ukuphucula ukusebenza, ukubambelela kunye nokuqina.
I-HEC ibonisa ukuhambelana okugqwesileyo kunye nezinye izithako ezisetyenziswa ngokuqhelekileyo ekuqulunqweni, kubandakanywa i-surfactants, i-salts, kunye ne-preservatives. Oku kuhambelana kuvumela ukudityaniswa lula kwiindlela ezahlukeneyo zemveliso ngaphandle kokubeka esichengeni uzinzo okanye ukusebenza.
Iingqwalasela zokusingqongileyo zikwadlala indima ekusetyenzisweni kwe-HEC. Njengepolymer evuselelekayo kunye ne-biodegradable evela kwi-cellulose, i-HEC inikezela ngenye indlela ezinzileyo kwii-synthetic thickeners kunye nezinzisi ezivela kwimithombo yepetrochemical. Ngaphezu koko, i-biocompatibility yayo kunye nendalo engeyiyo ityhefu iyenza ilungele ukusetyenziswa kwiimveliso ezininzi zabathengi, ukunciphisa umngcipheko wezempilo kunye nokusingqongileyo.
I-HEC yikhompawundi yeekhemikhali ezisebenzayo ezinoluhlu olubanzi lwezicelo kuwo wonke amashishini ahlukeneyo. Iimpawu zayo ezizodwa njenge-thickener, i-rheology modifier, i-stabilizer, kunye ne-arhente yokugcina amanzi yenza ukuba ibe yinto ebaluleke kakhulu ekuqulunqweni kweemveliso ezininzi, ukusuka kwizinto zokunyamekela komntu ukuya kwizinto zokwakha. Njengoko amashishini aqhubeka nokubeka phambili ukusebenza, ukuzinza, kunye nokhuseleko lwabathengi, ukubaluleka kwe-HEC kwizicelo zeekhemikhali kunokwenzeka ukuba kunyamezele kwaye kuguquke kwiminyaka ezayo.
