Izakhiwo kanye nokuphepha kwe-hydroxyethyl cellulose

I-Hydroxyyethyl cellulose (HEC) i-White noma ikhambi eliphuzi, eliphuzi, elingenasici I-Selloluc Soluble Cellulose Afers. Ngaphezu kokuqina, ukumisa, ukubopha, ukuntanta, ukuntanta, ukuhlasela, ukusabalalisa, ukugcinwa kwamanzi kanye nokuhlinzeka nge-colloid elandelayo, inezakhiwo ezilandelayo:

1. I-HEC incane emanzini ashisayo noma amanzi abandayo, izinga lokushisa eliphakeme noma elibilayo ngaphandle kwezulu, ukuze libe nohlu olubanzi lwe-soubity kanye ne-viscosity, ne-gelation engeyona eyeshisayo;

2 Kungumkhulu we-colloidal omkhulu omuhle kakhulu wezixazululo eziphakeme ze-electrolyte;

I-3. Umthamo wokugcina amanzi uphakeme kabili njenge-methyl cellulose, futhi inomthethonqubo ongcono wokugeleza.

4. Uma uqhathanisa ne-methyl cellulose ye-methyl kanye ne-hydroxypropylm methyl celtule, amandla asabalalisayo ka-HEC yimbi kakhulu, kepha ikhono le-colloid elivikelayo linamandla. Ngenxa yezakhiwo zayo ezinhle zokuqina, ukumisa, ukusabalalisa, ukunamathela, ukunamathela, ukuvikela amafilimu, ukuvikela umswakama nokunikeza umswakama, ukunikela, umuthi, i-polymerization kanye nezinye izinkambu.

Izinyathelo zokuzivikela:

Njengoba i-hydroxyyethyll ephethwe yi-cardroxyethyl ephethwe yi-powder noma i-cellulose iqinile, kulula ukuyiphatha futhi iwukhiphe ngamanzi inqobo nje uma izinto ezilandelayo zinakekelwa. le khasi

1. Ngaphambi nangemva kokungeza i-hydroxyethyl cellulose, kufanele ivuswe ngokuqhubekayo kuze kube yilapho isixazululo sisobala futhi sicacile. le khasi

2. Kumele itholakale kancane ethangini lokuxuba, ungangezi ngokuqondile inani elikhulu le-hydroxyethyl cellulose noma i-hydroxyethyl celtulose eyenziwe ama-lumps namabhola ethangini lokuxuba. le khasi

I-3. Izinga lokushisa lamanzi nenani le-PH emanzini linobudlelwano obusobala ekuchitheni kwe-hydroxyethyl cellulose, ngakho-ke kufanele kukhokhwe. le khasi

4. Ungangezi ezinye izinto ze-alkaline engxube ngaphambi kwe-hydroxyethyl cellulose powder kufudunyezwa emanzini. Ukuphakamisa Inani le-PH ngemuva kokufudumala kuzosiza ukuncibilikisa. le khasi

I-5. Ngokusemandleni akho, engeza i-anti-fungal agent ngokushesha ngangokunokwenzeka. le khasi

6. Lapho usebenzisa i-High-Viscoxyethyl cellulose, ukugcwaliswa kotshwala bamama akufanele kube ngaphezulu kuka-2,5-3%, ngaphandle kwalokho utshwala buzoba nzima ukuphatha. I-hydroxyyethylyl ephathekayo ephathisiwe ngokuvamile ayikho lula ukwakha izigaxa noma ama-sphere, futhi ngeke isebenzise ama-colloids we-infolluble spherical ngemuva kokungeza amanzi.
