Kukhona i-industrial monosodium glutamate, i-carboxymethyl cellulose, i-hydroxypropyl methyl cellulose, kanyei-hydroxyethyl cellulose, okuyizona ezisetshenziswa kakhulu. Phakathi kwezinhlobo ezintathu ze-cellulose, okunzima kakhulu ukuhlukanisa i-hydroxypropyl methylcellulose ne-hydroxyethyl cellulose. Ake sihlukanise lezi zinhlobo ezimbili ze-cellulose ngokusetshenziswa nemisebenzi yazo.
Njenge-surfactant engeyona i-ionic, i-hydroxyethyl cellulose inalezi zinto ezilandelayo ngaphezu kokumisa, ukujiya, ukuhlakaza, ukuntanta, ukubopha, ukwenza ifilimu, ukugcinwa kwamanzi nokuhlinzeka ngama-colloid avikelayo:
1. I-HEC ngokwayo ayiyona i-ionic futhi ingahlala nohlu olubanzi lwama-polymers ancibilika emanzini, ama-surfactants, nosawoti. Kuyi-thickener enhle kakhulu ye-colloidal equkethe izixazululo ze-electrolyte zokugxila okuphezulu.
2. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa i-colloid evikelayo inamandla amakhulu.
3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono.
4. I-HEC iyancibilika emanzini ashisayo noma abandayo, futhi ayidli ekushiseni okuphezulu noma ekubiliseni, ngakho-ke inohlu olubanzi lwezimpawu ze-solubility kanye ne-viscosity, kanye ne-gelation engashisi.
Ukusetshenziswa kwe-HEC: ngokuvamile kusetshenziswa njenge-ejenti yokuqina, i-ejenti evikelayo, i-adhesive, stabilizer kanye nokulungiswa kwe-emulsion, i-jelly, i-ointment, i-lotion, i-eye clearing.
Isingeniso sohlelo lokusebenza lwe-Hydroxypropyl methylcellulose (HPMC):
1. Imboni yokugqoka: njenge-thickener, dispersant kanye ne-stabilizer embonini yokugqoka, inokuhambisana okuhle emanzini noma ku-organic solvents. njengesikhiphi sikapende.
2. Ukwenziwa kwe-Ceramic: isetshenziswa kabanzi njengesibophezelo ekwenzeni imikhiqizo yobumba.
3. Abanye: Lo mkhiqizo futhi usetshenziswa kabanzi embonini yesikhumba, yemikhiqizo yephepha, ukulondolozwa kwezithelo nemifino kanye nemboni yendwangu, njll.
4. Ukuphrinta kukayinki: njenge-thickener, dispersant kanye ne-stabilizer embonini ye-inki, inokuhambisana okuhle emanzini noma ku-organic solvents.
5. Ipulasitiki: isetshenziswa njenge-ejenti yokukhulula isikhunta, isithambile, isithambiso, njll.
6. I-Polyvinyl chloride: Isetshenziswa njengesisabalalisi ekukhiqizeni i-polyvinyl chloride, futhi iyisisetshenziswa esiyinhloko sokulungiswa kwe-PVC ngokumiswa kwe-polymerization.
7. Imboni yezokwakha: Njenge-ejenti egcina amanzi kanye ne-retarder ye-slurry yesihlabathi sikasimende, yenza udaka lwesihlabathi lumpompeke. Isetshenziswa njengesibophezelo ekunamekelweni kokunamathisela, i-gypsum, i-putty powder noma ezinye izinto zokwakha ukuze kuthuthukiswe ukusabalala nokwelula isikhathi sokusebenza. Isetshenziswa njenge-paste ye-ceramic tile, imabula, umhlobiso wepulasitiki, njengesithuthukisi sokunamathisela, futhi inganciphisa inani likasimende. Ukugcinwa kwamanzi kwe-HPMC kungavimbela udaka ekuqhekekeni ngenxa yokoma ngokushesha ngemva kokufaka isicelo, futhi kuthuthukise amandla ngemva kokuqina.
