Ukusetyenziswa kwe-hydroxyethyl cellulose

Njenge-non-ionic surfactant, i-hydroxyethyl cellulose inezi mpawu zilandelayo ukongeza kwimisebenzi yokumisa, ukuqina, ukusabalalisa, ukudada, ukubopha, ukwenza ifilimu, ukugcinwa kwamanzi kunye nokubonelela nge-colloid yokukhusela:

1. I-HEC iyancibilika emanzini atshisayo okanye kumanzi abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, ukwenzela ukuba inoluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gelation engeyona i-thermal;

2. Xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose, ikhono lokusabalalisa i-HEC libi kakhulu, kodwa ikhono lokukhusela i-colloid linamandla.

3. Umthamo wokugcinwa kwamanzi uphindwe kabini kunalowo we-methyl cellulose, kwaye unolawulo olungcono lokuhamba.

Izilumkiso xa usebenzisa:

Ekubeni i-cellulose ye-hydroxyethyl ephathwayo i-powder okanye i-cellulose eqinile, kulula ukuyiphatha kunye nokuyinyibilika emanzini nje ukuba ezi zinto zilandelayo ziqwalaselwe.

1. Ngaphambi nangemva kokongeza i-hydroxyethyl cellulose, kufuneka iqhutywe ngokuqhubekayo de isisombululo sibonakale ngokucacileyo kwaye sicace.

2. Kufuneka ihlulwe ngokuthe chu kwi-tank yokuxuba, ungafaki ngokuthe ngqo inani elikhulu le-hydroxyethyl cellulose eyenze izibonda okanye iibhola kwi-tank yokuxuba.

3. Ubushushu bamanzi kunye nexabiso le-PH emanzini linobudlelwane obucacileyo bokuchithwa kwe-hydroxyethyl cellulose, ngoko ke ingqwalasela ekhethekileyo kufuneka ihlawulwe.

4. Musa ukongeza ezinye izinto zealkaline kumxube phambi kokuba umgubo we-hydroxyethyl cellulose ufudunyezwe ngamanzi. Ukuphakamisa ixabiso le-PH emva kokufudumala kuya kunceda ukunyibilika.

I-HEC isebenzisa:

1. Ngokuqhelekileyo isetyenziswe njenge-thickener, i-agent ekhuselayo, i-adhesive, i-stabilizer, kunye ne-additive yokulungiswa kwe-emulsions, i-jellies, i-ointments, i-lotions, i-eye cleaners, i-suppositories kunye neepilisi, kwaye iphinda isetyenziswe njenge-gel hydrophilic kunye ne-skeleton Materials. ukulungiswa kohlobo lwe-matrix oluzinzileyo lokukhululwa kwamalungiselelo, kwaye lunokusetyenziswa njengento yokuzinzisa ekutyeni.

2. Isetyenziswa njenge arhente yokulinganisa kushishino lwempahla olulukiweyo, kwaye njenge arhente encedisayo kwibhondi, ukujiya, emulsifying, kunye nokuzinzisa kumacandelo ombane kunye nokukhanya.

3. Isetyenziswa njenge-thickener kunye nesinciphisi sokulahleka kolwelo kulwelo olusekwe emanzini kunye nolwelo lokugqibezela, kwaye umphumo wokuqina uyabonakala kulwelo lokugrumba i-brine. Isenokusetyenziswa njengesinciphisi ilahleko ulwelo kwi oyile kakuhle isamente. Inokudityaniswa kunye ne-polyvalent metal ions ukwenza ijeli.

4. Le mveliso isetyenziselwa i-dispersant ye-polymerization ye-petroleum yamanzi-based gel fracturing fluid, i-polystyrene kunye ne-polyvinyl chloride, njl. Isenokusetyenziswa njenge-emulsion thickener kwishishini lepeyinti, i-hygrostat kwishishini le-electronics, i-anticoagulant ye-cement kunye ne-agent yokugcinwa komswakama kwishishini lokwakha. I-Ceramic industry glazing kunye ne-toothpaste binder. Ikwasetyenziswa ngokubanzi ekushicileleni nasekudayeni, amalaphu, ukwenza iphepha, amayeza, ucoceko, ukutya, imidiza, izibulali-zinambuzane kunye nezinto zokucima umlilo.
