Yintoni uMahluko we-HPMC kunye ne-HEC?

I-HPMC yiHydroxypropyl methyl cellulose ether kwaye iHEC yihydroxyethyl cellulose ether.

Intshayelelo yeHydroxypropyl methyl cellulose (HPMC):

1, ishishini lolwakhiwo: njengamanzi kunye nentlenga yentlenga yokugcina amanzi, iretarder ukwenza ukumpompa okudaka. Kwi-plastering, i-gypsum, i-putty powder okanye ezinye izinto zokwakha njenge-adhesive, phucula i-daub kunye nokwandisa ixesha lokusebenza. Isetyenziselwa ukuncamathelisa ithayile ye-ceramic, ilitye lebhastile, ukuhombisa iplastiki, intlama yokuqinisa i-arhente, isenokunciphisa idosi yesamente.HPMCukusebenza kokugcinwa kwamanzi kwenza i-slurry emva kokusetyenziswa akuyi kuba ngenxa yokoma ngokukhawuleza kunye nokuqhekeka, ukuphucula amandla emva kokuqina.

I-2, ukwenziwa kwe-ceramic: isetyenziswa ngokubanzi njengento yokuncamathelisa kwimveliso ye-ceramic.

I-3, i-coating industry: kwi-coating industry njenge-thickener, i-dispersant kunye ne-stabilizer, emanzini okanye i-solvents ye-organic ine-solubility efanelekileyo. Njengento yokususa ipeyinti.

I-4, inki yoshicilelo: kwishishini le-inki njenge-thickener, i-dispersant kunye ne-stabilizer, emanzini okanye i-solvents ye-organic ine-solubility efanelekileyo.

I-5, iplastiki: ukwenza i-arhente yokukhululwa, i-softener, i-lubricant, njl.

I-6, i-PVC: imveliso ye-PVC njenge-dispersant, ukulungiswa kwe-polymerization yokumiswa kwee-PVC eziphambili. I-7, Abanye: le mveliso ikwasetyenziswa ngokubanzi kwimveliso yesikhumba, imveliso yephepha, ukugcinwa kweziqhamo kunye nemifuno kunye noshishino lwamalaphu.

Intshayelelo ye-Hydroxyethyl cellulose (HEC):

HEC Iselulosi yeHydroxyethyl, njengohlobo lwe-nonionic surfactant, ngaphandle kokuqina, ukudada, ukudada, kunye nokwenza ifilimu, ukusasazwa, amanzi, kunye nokubonelela nge-colloid ekhuselayo, nayo ineempawu ezilandelayo:

I-1, i-HEC i-soluble emanzini ashushu okanye amanzi abandayo, ashushu okanye abilayo kungekhona imvula, yenza ukuba ibe noluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gel non thermal;

I-2, i-non-ionic yayo inokuhlalisana kunye noluhlu olubanzi lwezinye iipolymers ezinyibilikayo zamanzi, i-surfactants, i-salts, i-colloidal thickener egqwesileyo equlethe i-concentration ephezulu yesisombululo se-electrolyte;

I-3, amandla okugcina amanzi aphindwe kabini ngaphezu kwe-methyl cellulose, kunye nolawulo oluhle lokuhamba, i-4, i-HEC isakhono sokusasazeka xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose isakhono sokusasazeka yeyona nto imbi kakhulu, kodwa amandla okukhusela i-colloidal yeyona nto inamandla.

Ukusetyenziswa: ngokuqhelekileyo isetyenziswe njenge-agent edibeneyo, i-agent ekhuselayo, i-adhesive, i-stabilizer kunye ne-additive ekulungiseleleni i-emulsion, i-jelly, i-ointment, i-lotion, i-ejenti yokucoca amehlo, i-suppository kunye ne-tablet, ekwasetyenziswa njenge-hydrophilic gel, i-skeleton material, ukulungiswa kwe-skeleton yohlobo lokukhululwa okuqhubekayo. ukulungiswa, kusenokusetyenziswa njenge-stabilizer ekutyeni.
