Makhalidwe ndi Ntchito za Hydroxyethyl Methyl Cellulose HEMC

Waukulu makhalidwe ahydroxyethyl methyl cellulose (HEMC)ndi:

1. Kusungunuka: kusungunuka m'madzi ndi zina zosungunulira zamoyo, HEMC ikhoza kusungunuka m'madzi ozizira, kusungunuka kwake kwakukulu kumangotsimikiziridwa ndi kukhuthala, kusungunuka kumasiyana ndi mamasukidwe akayendedwe, kutsika kwa kukhuthala, kumapangitsanso kusungunuka.

2. Kukana kwa mchere: Mankhwala a HEMC ndi osakhala a ionic cellulose ethers ndipo si polyelectrolytes, kotero pamaso pa mchere wachitsulo kapena ma electrolyte achilengedwe, amakhala okhazikika muzitsulo zamadzimadzi, koma kuwonjezera kwambiri kwa electrolyte kungayambitse gelation ndi mpweya.

3. Ntchito yapamtunda: Chifukwa njira yamadzimadzi imakhala ndi ntchito yapamtunda, imatha kugwiritsidwa ntchito ngati chitetezo cha colloid, emulsifier ndi dispersant.

4. Thermal gel osakaniza: PameneMtengo HEMCmankhwala amadzimadzi njira ndi usavutike mtima ndi kutentha kwina, amakhala opaque, gel osakaniza, ndi kupanga mpweya, koma pamene mosalekeza utakhazikika, amabwerera ku njira yothetsera vutoli, ndipo gel osakaniza ndi mpweya zimachitika. Kutentha makamaka kumadalira mafuta awo, kuyimitsa zothandizira, zoteteza colloids, emulsifiers, etc.

5. Metabolic inertness ndi fungo lochepa ndi fungo labwino: HEMC imagwiritsidwa ntchito kwambiri muzakudya ndi zamankhwala chifukwa siyimapangidwa ndipo imakhala ndi fungo lochepa komanso fungo labwino.

6. Antifungal: HEMC ili ndi mphamvu yabwino ya antifungal komanso kukhazikika kwa viscosity panthawi yosungirako nthawi yayitali.

7. Kukhazikika kwa PH: Kuthamanga kwa mankhwala a HEMC amadzimadzi amadzimadzi sikukhudzidwa kwambiri ndi asidi kapena alkali, ndipo pH mtengo ndi wosasunthika pakati pa 3.0-11.0.

Kugwiritsa ntchito kwaHydroxyethyl methyl cellulose (HEMC):

Hydroxyethyl methyl cellulose angagwiritsidwe ntchito ngati colloid zoteteza wothandizila, emulsifier ndi dispersant chifukwa pamwamba yogwira ntchito mu njira amadzimadzi. Chitsanzo cha ntchito yake ndi motere: Zotsatira za hydroxyethyl methyl cellulose pa katundu wa simenti. Hydroxyethyl methyl cellulose ndi ufa woyera wopanda fungo, wosakoma, wopanda poizoni womwe umasungunuka m'madzi ozizira kuti ukhale wowoneka bwino, wowoneka bwino. Lili ndi mphamvu zowonjezera, kumanga, kubalalika, emulsifying, kupanga mafilimu, kuyimitsa, kutsatsa, gelling, pamwamba, kusunga chinyezi ndi kuteteza colloids. Chifukwa cha ntchito yogwira ntchito ya njira yamadzimadzi, imatha kugwiritsidwa ntchito ngati colloid protective agent, emulsifier ndi dispersant. Hydroxyethyl methyl cellulose aqueous solution ili ndi hydrophilicity yabwino ndipo ndi yosunga bwino madzi.
