Ukusetshenziswa okuyinhloko kanye nomehluko we-hydroxypropyl methylcellulose HPMC kanye ne-hydroxyethyl cellulose HEC

I-Carboxymethyl cellulose, i-hydroxypropyl methyl cellulose, ne-hydroxyethyl cellulose ene-industrial monosodium glutamate isetshenziswa ngenani elikhulu kakhulu.Okunzima kakhulu ukuhlukanisa phakathi kwalezi zinhlobo ezintathu ze-cellulose i-hydroxypropyl methylcellulose ne-hydroxyethyl cellulose.Ngezansi sizohlukanisa lezi zinhlobo ezimbili ze-cellulose ngokusetshenziswa nokusebenza kwazo.

Njenge-surfactant engeyona i-ionic, i-hydroxyethyl cellulose inalezi zakhiwo ezilandelayo ngaphezu kwemisebenzi yokumisa, ukuqina, ukuhlakaza, ukuntanta, ukubopha, ukwenza ifilimu, ukugcinwa kwamanzi nokuhlinzeka nge-colloid evikelayo:

1. I-HEC ngokwayo ayiyona i-ionic futhi ingahlala nohlu olubanzi lwama-polymers ancibilika emanzini, ama-surfactants, nosawoti.Kuyi-colloidal thickener enhle kakhulu yezixazululo eziqukethe ama-electrolyte agxile kakhulu.

2. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa ikhono le-colloid lokuvikela liqine kakhulu.

3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono.

4. I-HEC iyancibilika emanzini ashisayo noma emanzini abandayo, futhi ayidli ngokushisa okuphezulu noma ukubilisa, okwenza ibe nohlu olubanzi lwezimpawu ze-solubility kanye ne-viscosity, kanye ne-gelation engashisi.

Ukusetshenziswa kwe-HEC: ngokuvamile kusetshenziswa njenge-thickener, i-ejenti yokuzivikela, i-adhesive, stabilizer kanye nokulungiswa kwe-emulsion, i-jelly, i-ointment, i-lotion, iso elicacile.

Isingeniso sohlelo lokusebenza lwe-Hydroxypropyl methylcellulose (HPMC):

1. Imboni yokumboza: Isetshenziswa njenge-thickener, dispersant kanye ne-stabilizer embonini yokugqoka, futhi inokuhambisana okuhle emanzini noma ku-organic solvents.Njengesikhiphi sikapende.

2. Imboni yokukhiqiza i-Ceramic: Isetshenziswa kakhulu njengesibophezelo ekwenzeni imikhiqizo yobumba.

3. Abanye: Lo mkhiqizo usetshenziswa kakhulu esikhumbeni, emikhiqizweni yephepha, ekugcinweni kwezithelo nemifino kanye nezimboni zendwangu, njll.

4. Ukuphrinta kukayinki: Isetshenziswa njenge-thickener, dispersant and stabilizer embonini ye-inki, futhi inokuhambisana okuhle emanzini noma izincibilikisi zemvelo.

5. Ipulasitiki: isetshenziswa njengokwakha i-ejenti yokukhulula, isithambile, isithambiso, njll.

6. I-Polyvinyl chloride: Isetshenziswa njenge-disperant ekukhiqizeni i-polyvinyl chloride, futhi iyi-ejenti eyinhloko eyisizayo yokulungiselela i-PVC ngokumiswa kwe-polymerization.i

7. Imboni yezokwakha: Njenge-ejenti egcina amanzi kanye ne-retarder ye-slurry yesihlabathi sikasimende, ingenza udaka lumpompeke.Ku-plaster, i-gypsum, i-putty powder noma ezinye izinto zokwakha njengesibopho sokuthuthukisa ukusabalala nokwandisa isikhathi somsebenzi.Ingasetshenziswa njenge-paste tile, imabula, umhlobiso wepulasitiki, ukuqinisa unamathisele, futhi inganciphisa inani likasimende.Ukusebenza kokugcina amanzi kwe-HPMC kuvimbela udaka ekuqhekekeni ngenxa yokoma ngokushesha ngemva kokufakwa, futhi kuthuthukisa amandla ngemva kokuqina.
