Ukusetshenziswa kwe-hydroxyethyl cellulose

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 iyancibilika emanzini ashisayo noma emanzini abandayo, futhi ayidli ngokushisa okuphezulu noma ukubila, ukuze ibe nezici eziningi zokuncibilika kanye nezici ze-viscosity, kanye ne-gelation engashisi;

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.

Izinyathelo zokuqapha lapho usebenzisa:

Njengoba i-hydroxyethyl cellulose ehlanjululwe phezulu iyimpushana noma i-cellulose eqinile, kulula ukuyiphatha futhi iyincibilikise emanzini inqobo nje uma izinto ezilandelayo zinakwa.

1. Ngaphambi nangemva kokwengeza i-hydroxyethyl cellulose, kufanele inyakaziswe ngokuqhubekayo kuze kube yilapho isisombululo sisobala ngokuphelele futhi sicacile.

2. Kumele ihlungwe kancane kancane ethangini lokuxuba, ungafaki ngokuqondile inani elikhulu le-hydroxyethyl cellulose eyenze izigaxa noma amabhola ethangini lokuxuba.

3. Izinga lokushisa lamanzi kanye nenani le-PH emanzini kunobudlelwane obusobala nokuqedwa kwe-hydroxyethyl cellulose, ngakho-ke kufanele kuqashelwe ngokukhethekile.

4. Ungafaki ezinye izinto ezine-alkali engxubeni ngaphambi kokuba i-hydroxyethyl cellulose powder ifudunyezwe ngamanzi. Ukuphakamisa inani elingu-PH ngemva kokufudumala kuzosiza ukuncibilika.

I-HEC isebenzisa:

1. Ngokuvamile isetshenziswa njenge-thickener, i-ejenti evikelayo, i-adhesive, stabilizer, kanye nesengezo sokulungiselela ama-emulsions, ama-jellies, amafutha okugcoba, ama-lotions, izihlanzi zamehlo, ama-suppositories namaphilisi, futhi isetshenziswa njengejeli le-hydrophilic kanye ne-skeleton Materials, ukulungiswa kohlobo lwe-matrix amalungiselelo okukhululwa okuqhubekayo, futhi kungasetshenziswa njengesiqinisi ekudleni.

2. Isetshenziswa njenge-ejenti yokulinganisa embonini yendwangu, futhi njenge-ejenti eyisizayo yokuhlanganisa, ukujiya, ukuqinisa, nokusimamisa emikhakheni ye-electronics kanye nemboni yokukhanya.

3. Isetshenziswa njengesinciphisi sokujiyisa kanye nesinciphisi sokulahlekelwa uketshezi kuketshezi lokumba olusekelwe emanzini kanye noketshezi oluqedayo, futhi umphumela wokujiya ubonakala oketshezini lokumba olune-brine. Ingasetshenziswa futhi njengesinciphisi sokulahlekelwa uketshezi losimende womthombo wamafutha. Ingaxhunyaniswa ne-polyvalent metal ions ukwenza ijeli.

4. Lo mkhiqizo usetshenziswa njenge-dispersant ye-polymerization ye-petroleum yamanzi-based gel fracturing fluid, i-polystyrene ne-polyvinyl chloride, njll. Ingasetshenziswa futhi njenge-emulsion thickener embonini yepende, i-hygrostat embonini ye-electronics, i-anticoagulant ye-cement kanye ne-ejenti yokugcina umswakama embonini yezokwakha. I-Ceramic industry glazing kanye ne-toothpaste binder. Ibuye isetshenziswe kabanzi ekunyatheliseni nasekudayeni, izindwangu, ukwenza amaphepha, imithi, inhlanzeko, ukudla, ugwayi, izibulala-zinambuzane kanye nezinto ezicisha umlilo.
