Makhalidwe ndi Ntchito za Hydroxyethyl Methyl Cellulose HEMC

Makhalidwe akuluakulu ahydroxyethyl methyl cellulose (HEMC)ndi:

1. Kusungunuka: Kusungunuka m'madzi ndi zinthu zina zachilengedwe, HEMC imatha kusungunuka m'madzi ozizira, kuchuluka kwake kwakukulu kumangotsimikiziridwa ndi kukhuthala, kusungunuka kumasiyana malinga ndi kukhuthala, kukhuthala kutsika, kusungunuka kumakulirakulira.

2. Kukana Mchere: Zopangidwa ndi HEMC ndi ma ether a cellulose omwe si a ionic ndipo si ma polyelectrolyte, kotero pakakhala mchere wachitsulo kapena ma electrolyte achilengedwe, zimakhala zokhazikika m'madzi amadzi, koma kuwonjezera ma electrolyte kwambiri kungayambitse kufalikira kwa madzi ndi mvula.

3. Ntchito ya pamwamba: Popeza madzi amadzi ali ndi ntchito ya pamwamba, angagwiritsidwe ntchito ngati choteteza cha colloid, emulsifier ndi dispersant.

4. Gel yotenthetsera: PameneHEMCMadzi amadzi a chinthucho amatenthedwa kufika kutentha kwinakwake, amakhala osawoneka bwino, ma gels, ndipo amapanga precipitate, koma akazizira nthawi zonse, amabwerera ku momwe yankho lake linalili poyamba, ndipo gel iyi ndi mvula zimachitika. Kutentha kwake kumadalira makamaka mafuta awo, zothandizira zopachikira, ma colloids oteteza, ma emulsifiers, ndi zina zotero.

5. Kusagwira bwino ntchito kwa kagayidwe kachakudya komanso fungo lochepa: HEMC imagwiritsidwa ntchito kwambiri mu chakudya ndi mankhwala chifukwa siigwiritsidwa ntchito mopitirira muyeso ndipo ili ndi fungo lochepa komanso fungo lochepa.

6. Woletsa bowa: HEMC ili ndi mphamvu yabwino yolimbana ndi bowa komanso kulimba bwino kwa mabakiteriya akasungidwa kwa nthawi yayitali.

7. Kukhazikika kwa PH: Kukhuthala kwa yankho lamadzi la HEMC sikukhudzidwa kwambiri ndi asidi kapena alkali, ndipo pH ndi yokhazikika pakati pa 3.0-11.0.

Kugwiritsa ntchitoHydroxyethyl methyl cellulose (HEMC)：

Hydroxyethyl methyl cellulose ingagwiritsidwe ntchito ngati choteteza cha colloid, emulsifier ndi dispersant chifukwa cha ntchito yake yogwira ntchito pamwamba pa madzi. Chitsanzo cha momwe imagwiritsidwira ntchito ndi ichi: Mphamvu ya hydroxyethyl methyl cellulose pa makhalidwe a simenti. Hydroxyethyl methyl cellulose ndi ufa woyera wopanda fungo, wopanda kukoma, wopanda poizoni womwe umasungunuka m'madzi ozizira kuti upange yankho lomveka bwino komanso lokhuthala. Ili ndi makhalidwe monga kukhuthala, kumangirira, kufalitsa, kusakaniza, kupanga filimu, kuyimitsa, kusakaniza, gelling, kugwira ntchito pamwamba, kusunga chinyezi ndi kuteteza ma colloid. Chifukwa cha ntchito yogwira ntchito pamwamba pa madzi, ingagwiritsidwe ntchito ngati choteteza cha colloid, emulsifier ndi dispersant. Hydroxyethyl methyl cellulose aqueous solution ili ndi hydrophilicity yabwino ndipo ndi yothandiza kwambiri kusunga madzi.
