I-Hydroxyethyl cellulose (HEC) kunye ne-hydroxypropyl methyl cellulose (HPMC) zezona zisetyenziswa ngokuqhelekileyo zityebe.Ziyi-adhesives ze-elastic adhesives ezingasetyenziselwa ukubonelela ukuchasana, ukwandisa i-viscosity, okanye ukubonelela nge-ductility.Ukwakheka kweekhemikhali zabo kuyafana, kodwa kukho umahluko ocacileyo.
I-HEC yi-analogue ye-ethylene-acetate equka ikakhulu i-formaldehyde, i-methanol kunye ne-sodium hydroxide.I-thixotropic kakhulu kwaye inokusetyenziswa njengezinto zokuthambisa, ii-agent zonyango ezingaphezulu kunye ne-adhesives kwizixhobo zombane kunye nezoshishino.I-Hecs inokusetyenziswa njengezinto ezityebileyo, ii-dispersants kunye ne-scale inhibitors.
HPMC yenye analogue ethylene-acetate, equlathe ikakhulu methanol, sodium hydroxide, kunye carbonate.Ine-viscosity ephezulu, i-elasticity kunye nokwandiswa, ingasetyenziswa njengezinto zokuncamathelisa, iipeyinti, izicoci kunye nezongezo ze-inki.Ukongeza, ingasetyenziselwa ukulungiswa kwekristale kwaye inozinzo lwenkqubo egudileyo.
I-Hydroxyethyl cellulose HEC, njenge-surfactant engeyiyo i-ionic, inezi mpawu zilandelayo ngaphezu kokuqina, ukumiswa, ukunamathela, ukudada, ukubunjwa kwefilimu, ukusabalalisa, ukugcinwa kwamanzi kunye nemiphumo ekhuselayo ye-colloidal:
I-1, i-hydroxyethyl cellulose HEC inokuchithwa kumanzi ashushu okanye abandayo, ukushisa okuphezulu okanye ukubilisa akunqandeki, ukwenzela ukuba ibe noluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye nepropati ye-gel engeyiyo eshushu;
I-2, i-hydroxyethyl cellulose HEC ngokwayo uhlobo lwe-non-ionic lunokubambisana kunye noluhlu olubanzi lwezinye iipolymers ezinyibilikayo zamanzi, i-surfactants, i-salts, luhlobo lwe-colloidal thickener equlethe isisombululo esiphezulu se-electrolyte;
I-3, i-hydroxyethyl cellulose i-HEC umthamo wokugcina amanzi uphindwe kabini kune-methyl cellulose, kunye nokulawulwa kokuhamba;
4. Ikhono lokusasazwa kwe-hydroxyethyl cellulose HEC ihlwempuzekile xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose, kodwa ukukhuselwa kwekhono le-colloid kunamandla.
Injongo: Ngokuqhelekileyo isetyenziswa njenge-agent agent, i-agent ekhuselayo, i-adhesive, i-stabilizer kunye nokulungiswa kwepeyinti ye-latex, i-lacquer, inki.Izongezo ezisetyenziselwa ukugaya ioli, i-gel, i-ointment, i-lotion, i-eye clearers, i-suppositories kunye neepilisi, ezikwasetyenziswa njenge-hydrophilic gels, izinto ze-skeleton, ukulungiswa kwe-skeleton eqhubekayo yokukhululwa, kwaye inokusetyenziswa njengezinzisi ekutyeni.
