Kodi MHEC ndi chiyani?

Methyl Hydroxyethyl Cellulose (MHEC) ndi chochokera ku cellulose ether yomwe imagwiritsidwa ntchito kwambiri m'mafakitale monga zomangamanga, zamankhwala, ndi zinthu zosamalira anthu.Amapangidwa ndikuchitapo kanthu pa cellulose ndi ethylene oxide ndi methyl chloride, zomwe zimapangitsa kuti pakhale gulu limodzi ndi magulu onse a hydroxyethyl ndi methyl omwe amamangiriridwa ku msana wa cellulose.

MHEC imagawana katundu wambiri ndi ma cellulose ethers monga Hydroxypropyl Methylcellulose (HPMC) ndi Hydroxyethyl Methylcellulose (HEMC), kuphatikizapo:

1. Kusungirako Madzi: MHEC imatha kuyamwa ndi kusunga madzi, ndikupangitsa kuti ikhale yothandiza pazinthu zomangira monga matope, ma grouts, ndi zomatira za matailosi kuti ateteze kuyanika msanga ndikuwongolera magwiridwe antchito.
2. Kunenepa: Kutha kuwonjezera mamasukidwe amadzimadzi amadzimadzi, omwe amakhala opindulitsa pakugwiritsa ntchito utoto, zokutira, ndi zinthu zosamalira munthu kuti akwaniritse mayendedwe omwe mukufuna.
3. Kukhazikika: MHEC imathandiza kukhazikika kwa emulsions ndi kuyimitsidwa, kuteteza kupatukana kwa gawo ndi kusunga homogeneity ya mankhwala.
4. Kupanga Mafilimu: Mofanana ndi ma cellulose ethers ena, MHEC ikhoza kupanga filimu yopyapyala ikagwiritsidwa ntchito pamtunda, kupereka chitetezo ndi kupititsa patsogolo kumamatira.
5. Katundu Woyenda Bwino: Itha kuwongolera mawonekedwe amayendedwe, kuwongolera kukonza ndi kugwiritsa ntchito.

MHEC nthawi zambiri imasankhidwa chifukwa cha kuphatikizika kwake kwapadera, monga kuthekera kwake kosungira madzi bwino ndikusunga mamasukidwe otsika poyerekeza ndi ma cellulose ethers ena.Izi zimapangitsa kuti zikhale zoyenera makamaka kwa ntchito zomwe kusungirako madzi kwakukulu kumafunika popanda kuonjezera kukhuthala kwa mapangidwe.

Methyl Hydroxyethyl Cellulose (MHEC) ndi yosunthika yochokera ku cellulose ether yokhala ndi ntchito zambiri, pomwe katundu wake monga thickener, stabilizer, water-reservation agent, and film kale ndi ofunika kwambiri.
