Sebopeho sa Lik'hemik'hale sa MHEC
MHEC e hlahisoa kecellulose ea tlhaho e matlafatsanglelihlopha tsa methyl le hydroxyethylLiphetoho tsena li ntlafatsaho qhibiliha ha metsi, ho teteana le ho lumellana ha 'onaka thepa e fapaneng.
Matlotlo a Bohlokoa a MHEC:
- Ho qhibiliha ha metsi: Ho qhibiliha metsing a chesang le a batang, ho etsa ditharollo tse hlakileng.
- Bokhoni ba ho teteana: E fana ka viscosity e phahameng le taolo e ntle ea rheology.
- Ho Boloka Metsi: Ho thibela tahlehelo ea metsi lihlahisoa tse thehiloeng ho samente le tse thehiloeng ho gypsum, ho ntlafatsa ho khomarela le ho khomarela.
- Tlhaho e seng ea Ionic: E lumellana le lik'hemik'hale tse fapaneng, ho kenyeletsoa le letsoai le li-surfactants.
- Bokhoni ba ho Etsa Filimi: E etsa lifilimi tse tenyetsehang le tse tšoarellang, tse molemo bakeng sa ho penta le ho sebelisa meriana.
- Ho Tsitsisa Thempereichara: E hanela mocheso, e leng se etsang hore e lokele ho sebediswa maemong a mocheso o phahameng.

Melemo ea ho Sebelisa MHEC
✔ Ho Boloka Metsi ka Botle – Ho thibela ho oma pele ho nako mesebetsing ea kaho le ea botle.
✔ Ho khomarela ho Ntlafalitsoeng – Ho ntlafatsa matla a ho khomarela likhomaretsing tsa thaele le li-mortar.
✔ E tsitsitse ho pholletsa le mefuta e mengata ea pH - E sebetsa ka katleho libakeng tse nang le asiti, tse sa nke lehlakore le tse nang le alkaline.
✔ Ho lumellana le Non-Ionic – E sebetsa hantle le letsoai, li-surfactant le li-polymer tse ling.
✔ E ntlafatsa Rheology le Litšobotsi tsa Phallo – E lumella ho teteana ho laolehang, e thibela ho rotha le ho thella.
