I-Hydroxyethyl Cellulose (HEC) yinto esetyenziswa ngokuqhelekileyo i-thickener, i-emulsifier kunye ne-stabilizer, esetyenziswa ngokubanzi kwiingubo, izithambiso, i-detergents, izinto zokwakha kunye nezinye iindawo. Umlinganiselo wokusetyenziswa kwawo udla ngokumiselwa ngokwemeko ethile yesicelo kunye neemfuno zokwenziwa.
1. Ishishini leeCoatings
Kwiingubo ezisekelwe emanzini, i-hydroxyethyl cellulose idla ngokusetyenziswa njenge-thickener kunye ne-agent yokumisa ukuncedisa ukulungelelanisa i-viscosity kunye ne-rheology yokugqoka. Ngokuqhelekileyo, umlinganiselo wokusetyenziswa ngu-0.1% ukuya kwi-2.0% (umlinganiselo wobunzima). Umlinganiselo othile uxhomekeke kuhlobo lokutyabeka, iipropati ezifunekayo ze-rheological kunye nokudibanisa kwezinye izithako.
2. Izithambiso kunye neemveliso zokhathalelo lomntu
Kwizinto zokuthambisa, i-hydroxyethyl cellulose isetyenziswa njenge-thickener kunye ne-stabilizer ukunceda ukuphucula ukuthungwa kunye nokusebenza kwesicelo semveliso. Umlinganiselo wokusetyenziswa oqhelekileyo ngu-0.1% ukuya kwi-1.0%. Ngokomzekelo, kwi-shampoo, isicoci sobuso, i-lotion kunye ne-gel, i-HEC inokubonelela kakuhle kunye nokuzinza.
3. Izicoci kunye nezokucoca
Kwizicoci zolwelo, i-hydroxyethyl cellulose isetyenziselwa ukulungelelanisa i-viscosity kunye nokumiswa kwemveliso kunye nokuthintela imvula yezinto eziqinileyo. Umlinganiselo wokusetyenziswa udla ngokuba yi-0.2% ukuya kwi-1.0%. Isixa se-HEC esisetyenziswe kwiintlobo ezahlukeneyo zeemveliso zokucoca zingahluka.
4. Izinto zokwakha
Kwizinto zokwakha, ezifana ne-cement slurry, i-gypsum, i-adhesives tile, njl., i-hydroxyethyl cellulose isetyenziselwa ukugcinwa kwamanzi kunye ne-thickener. Ngokuqhelekileyo, umlinganiselo wokusetyenziswa ngu-0.1% ukuya kwi-0.5%. I-HEC inokuphucula ukusebenza kokwakhiwa kwezinto, yandise ixesha lokusebenza, kwaye iphucule ipropathi echasene ne-sagging.
5. Ezinye izicelo
Iselulosi yeHydroxyethyl ikwasetyenziswa ngokubanzi kwezinye iindawo, ezinjengokutya namayeza. Umlinganiselo wokusetyenziswa udla ngokuhlengahlengiswa ngokweemfuno ezithile zesicelo. Ngokomzekelo, kwishishini lokutya, i-HEC ingasetyenziselwa njenge-thickener, i-stabilizer kunye ne-emulsifier, kwaye ukusetyenziswa kwayo ngokuqhelekileyo kuphantsi kakhulu.
Ukulumkela
Xa usebenzisa i-hydroxyethyl cellulose, kufuneka ubeke ingqalelo kula manqaku alandelayo:
Indlela yokuchithwa: I-solubility ye-HEC ichaphazeleka bubushushu, ixabiso le-pH kunye neemeko ezishukumisayo. Ngokuqhelekileyo kufuneka ifakwe kancinci emanzini kwaye ixutywe kakuhle.
Ukuhambelana kwefomula: Izithako zefomula ezahlukeneyo zinokuchaphazela ukusebenza kwe-HEC, ngoko ke uvavanyo lokuhambelana luyafuneka ngexesha lenkqubo yophuhliso loqulunqo.
Ulawulo lwe-Viscosity: Ngokweemfuno zemveliso yokugqibela, khetha uhlobo olufanelekileyo lwe-HEC kunye ne-dosage ukufezekisa i-viscosity efunekayo.
Umlinganiselo wokusetyenziswa kwe-hydroxyethyl cellulose yiparameter eguquguqukayo efuna ukulungiswa ngokwesicelo esithile kunye nokuqulunqwa. Ukuqonda ukusebenza kwe-HEC kwizicelo ezahlukeneyo kunokunceda ukwandisa ukusebenza kwemveliso kunye nomgangatho.
