Umahluko we-hydroxypropyl methylcellulose HPMC kunye ne-hydroxyethyl cellulose HEC

Kukho i-industrial monosodium glutamate, i-carboxymethyl cellulose, i-hydroxypropyl methyl cellulose, kunyei-hydroxyethyl cellulose, ezizezona zisetyenziswa kakhulu. Phakathi kweentlobo ezintathu zeselulosi, eyona nto inzima ukuhlula yi-hydroxypropyl methylcellulose kunye ne-hydroxyethyl cellulose. Makhe sahlule ezi ntlobo zimbini zeselulosi ngokusetyenziswa kwazo kunye nemisebenzi.

Njenge-non-ionic surfactant, i-hydroxyethyl cellulose inezi mpawu zilandelayo ukongeza ekumiseni, ukujiya, ukusabalalisa, ukudada, ukubopha, ukwenza ifilimu, ukugcinwa kwamanzi kunye nokubonelela ngee-colloids ezikhuselayo:

1. I-HEC ngokwayo ayinayo i-ionic kwaye inokuhlalisana kunye noluhlu olubanzi lwezinye iipolima ezinyibilikayo zamanzi, i-surfactants, kunye neetyuwa. Yinto egqwesileyo ye-colloidal thickener equlethe izisombululo eziphezulu ze-electrolyte.

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

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

4. I-HEC iyancibilika kumanzi ashushu okanye abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, ngoko inoluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gelation engeyona i-thermal.

Ukusetyenziswa kwe-HEC: ngokuqhelekileyo isetyenziswe njenge-agent edibeneyo, i-agent ekhuselayo, i-adhesive, i-stabilizer kunye nokulungiswa kwe-emulsion, i-jelly, i-ointment, i-lotion, i-eye clearing.

I-Hydroxypropyl methylcellulose (HPMC) ukuqaliswa kwesicelo:

1. Ishishini lokugubungela: njenge-thickener, dispersant kunye ne-stabilizer kwi-coating industry, inokuhambelana kakuhle kwamanzi okanye i-solvents eziphilayo. njengesixhobo sokususa ipeyinti.

2. Ukwenziwa kweCeramic: isetyenziswa ngokubanzi njenge-binder ekwenzeni iimveliso ze-ceramic.

3. Abanye: Le mveliso ikwasetyenziswa ngokubanzi kwesikhumba, ishishini lemveliso yephepha, ukugcinwa kweziqhamo kunye nemifuno kunye noshishino lwelaphu, njl.

4. Ukuprintwa kwe-Ink: njenge-thickener, dispersant kunye ne-stabilizer kwishishini le-inki, inokuhambelana kakuhle emanzini okanye kwi-solvents eziphilayo.

5. Iplastiki: isetyenziswe njenge-ejenti yokukhulula i-mold, i-softener, i-lubricant, njl.

6. I-Polyvinyl chloride: Isetyenziswa njenge-dispersant kwimveliso ye-polyvinyl chloride, kwaye iyeyona arhente incedisayo ekulungiseni i-PVC ngokumiswa kwepolymerization.

7. Ishishini lolwakhiwo: Njengearhente yokugcina amanzi kunye ne-retarder kudaka lwesanti yesamente, lenza ukuba udaka lwesanti lumpompeke. Isetyenziswe njengesibophelelo kwi-plastering paste, i-gypsum, i-putty powder okanye ezinye izinto zokwakha ukuphucula ukusasazeka kunye nokwandisa ixesha lokusebenza. Isetyenziswe njengentlama yethayile ye-ceramic, i-marble, i-plastic decoration, njenge-paste enhancer, kwaye inokunciphisa inani le-samente. Ukugcinwa kwamanzi kwe-HPMC kunokuthintela i-slurry ekuqhekekeni ngenxa yokoma ngokukhawuleza emva kwesicelo, kunye nokwandisa amandla emva kokuqina.
