Ukubaluleka nokusetshenziswa kwe-hydroxyethyl cellulose

1. Izakhiwo ze-hydroxyethyl cellulose

Lo mkhiqizo umhlophe noma ulula ophuzi wephunga eliphuzi futhi kulula ukugeleza kompunga, isilinganiso esingu-40 Mesh sches ≥99%; Ukushisa okuthambile: 135-140 ° C; Ubuningi obubonakalayo: 0.35-0.61G / ML; Ukushisa okuvumayo: 205-210 ° C; isivinini esivuthayo kancane; Ukushisa kwe-Equilibrium: 23 ° C; I-6% ku-50% RH, 29% ku-84% RH.

Kuyancibilika kuwo womabili amanzi abandayo namanzi ashisayo, futhi ngokuvamile awohliweyo ezinhlamvwini eziphilayo eziningi. I-viscosity ishintsha kancane ebangeni le-PH VAUR 2-12, kepha i-visa inciphisa ngaphezu kwaleli banga.

2. Izakhiwo ezibalulekile

Njenge-survic engekho, i-hydroxyyethyl cellulose inezinto ezilandelayo ngokungeziwe, ukumisa, ukubopha, ukuntanta, ukusabalalisa, ukusabalalisa, ukugcinwa kwamanzi kanye nokuhlinzeka ngamanzi nokuhlinzeka ngama-colloid avikelayo:

1. I-HEC incane emanzini ashisayo noma amanzi abandayo, futhi ayihlanganisi ekushiseni okuphezulu noma ukubilisa, okwenza kube nohlu olubanzi lwe-soubity, izici zokuvuselela kanye ne-gelation engeyona eye-armal.

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.

I-4. Uma uqhathanisa ne-methyl cellulose ye-methyl ne-hydroxypropyll methyl celtule, i-HEC inekhono elibi kakhulu lokusabalalisa, kepha amandla aqine kakhulu avikelayo.

3. Ukusetshenziswa kwe-hydroxyethyl cellulose

Ngokuvamile esetshenziswa njengabakhulu, ama-ejenti abavikelayo, ama-adhesive, abaqinisi kanye nezithasiselo zokulungiselela ama-emulsions, ama-jellies, ama-aintser, amaphilisi, futhi asetshenziswa ukulungiselela i-matrix-steres akulungiswa, futhi angasetshenziswa njenge-stabilizer ekudleni.
