Uyini Umehluko we-HPMC ne-HEC?

I-HPMC iyi-Hydroxypropyl methyl cellulose ether futhi i-HEC iyi-hydroxyethyl cellulose ether.

Isingeniso se-Hydroxypropyl methyl cellulose (HPMC):

1, imboni yezokwakha: njenge-ejenti yokugcina amanzi nodaka, i-retarder ukwenza ukupompa okunodaka.Ekukhometheni, i-gypsum, i-putty powder noma ezinye izinto zokwakha njenge-adhesive, thuthukisa i-daub futhi andise isikhathi sokusebenza.Isetshenziselwa ukunamathisela ithayela le-ceramic, imabula, umhlobiso wepulasitiki, i-ejenti yokuqinisa unamathisele, isenganciphisa umthamo usimende.I-HPMCukusebenza kokugcinwa kwamanzi kwenza i-slurry emva kokufaka isicelo ngeke ibe ngenxa yokoma ngokushesha kakhulu nokuqhekeka, kuthuthukise amandla ngemva kokuqina.

2, ukukhiqizwa kwe-ceramic: kusetshenziswa kabanzi njenge-adhesive ekukhiqizeni umkhiqizo we-ceramic.

I-3, imboni yokuhlanganisa: embonini yokumboza njenge-thickener, dispersant kanye ne-stabilizer, emanzini noma ku-organic solvents kune-solubility enhle.Njengesikhiphi sikapende.

I-4, ukuphrinta kwe-inki: embonini ye-inki njenge-thickener, dispersant kanye ne-stabilizer, emanzini noma izincibilikisi eziphilayo zine-solubility enhle.

5, ipulasitiki: ukwakha i-ejenti yokukhululwa, isithambile, okokugcoba, njll.

I-6, i-PVC: Ukukhiqizwa kwe-PVC njenge-dipersant, ukulungiswa kwe-polymerization yokumiswa kwezinsiza eziyinhloko ze-PVC.7, Abanye: lo mkhiqizo usetshenziswa kabanzi embonini yesikhumba, yemikhiqizo yephepha, ukulondolozwa kwezithelo nemifino kanye nomkhakha wezindwangu.

Isingeniso se-Hydroxyethyl cellulose (HEC):

I-HEC Hydroxyethyl cellulose, njengohlobo lwe-nonionic surfactant, ngaphandle kokujiya, ukuntanta, ukuntanta, nokwenza ifilimu, ukusabalalisa, amanzi, kanye nokuhlinzeka nge-colloid evikelayo, nayo inezindawo ezilandelayo:

I-1, i-HEC encibilika emanzini ashisayo noma emanzini abandayo, kushisa noma abilayo hhayi imvula, iyenze ibe nezinhlobonhlobo zezakhiwo ze-solubility kanye ne-viscosity, kanye nejeli engashisi;

2, i-non-ionic yayo ingahlala nohlu olubanzi lwama-polymers ancibilikayo emanzini, ama-surfactants, usawoti, i-colloidal thickener enhle kakhulu equkethe ukuhlushwa okuphezulu kwesisombululo se-electrolyte;

3, umthamo wokugcina amanzi uphakeme kabili kune-methyl cellulose, enomthetho wokugeleza okuhle, i-4, ikhono lokuhlakazeka kwe-HEC uma liqhathaniswa ne-methyl cellulose eyaziwayo kanye nekhono lokuhlakazeka kwe-hydroxypropyl methyl cellulose libi kakhulu, kodwa ikhono lokuvikela i-colloidal liqine kakhulu.

Ukusetshenziswa: ngokuvamile kusetshenziswa njenge-ejenti yokuqina, i-ejenti evikelayo, i-adhesive, stabilizer kanye nesengezo ekulungiseleleni i-emulsion, i-jelly, i-ointment, i-lotion, i-ejenti yokuhlanza amehlo, i-suppository kanye nethebhulethi, ebuye isetshenziswe njengejeli le-hydrophilic, i-skeleton material, ukulungiswa kohlobo lwamathambo ukukhululwa okuqhubekayo. ukulungiselela, ingasetshenziswa futhi njenge-stabilizer ekudleni.
