HPMC (Hydroxypropyl Methyl Cellulose) le HEMC (Hydroxy Ethyl Methyl Cellulose) ke li-ether tsa cellulose tse sebelisoang hangata thepa ea kaho ka lebaka la thepa ea tsona e ikhethang. Ke li-polymer tse qhibilihang ka metsing tse tsoang ho cellulose, polymer ea tlhaho e fumanoang maboteng a sele ea limela. HPMC le HEMC li sebelisoa e le lintho tse tlatsetsang lihlahisoa tse fapaneng tsa kaho ho ntlafatsa thepa ea tsona le ho ntlafatsa mokhoa oa ho sebetsa.
Tse latelang ke tse ling tsa lits'ebetso tsa HPMC le HEMC thepa ea kaho:
Likhomaretsi tsa Lithaele: Hangata HPMC le HEMC li eketsoa ho likhomaretsi tsa lithaele ho ntlafatsa ho sebetsa le matla a ho kopana. Li-polymer tsena li sebetsa e le li-thickeners, li fana ka nako e ntle ea ho buleha (nako eo sekhomaretsi se lulang se ka sebelisoa ka eona) le ho fokotsa ho thekesela ha lithaele. Li boetse li ntlafatsa ho khomarela ha sekhomaretsi ho li-substrate tse fapaneng.
Li-mortar tsa samente: HPMC le HEMC li sebelisoa ka har'a li-mortar tsa samente tse kang li-plaster, li-plaster le litsamaiso tsa ho qetela tsa ho kenya mocheso ka ntle (EIFS). Li-polymer tsena li ntlafatsa ho sebetsa ha seretse, li etsa hore ho be bonolo ho se hasanya le ho se sebelisa. Li boetse li ntlafatsa ho kopana, li fokotsa ho monngoa ha metsi le ho ntlafatsa ho khomarela ha li-mortar ho li-substrate tse fapaneng.
Lihlahisoa tse entsoeng ka gypsum: HPMC le HEMC li sebelisoa linthong tse entsoeng ka gypsum tse kang li-plaster tsa gypsum, metsoako ea manonyeletso le li-underlayment tse ikamahanyang le maemo. Li sebetsa e le lintho tse bolokang metsi, li ntlafatsa ho sebetsa le ho lelefatsa nako ea ho beha thepa. Li-polymer tsena li boetse li ntlafatsa ho hanyetsa mapetso, li fokotsa ho honyela le ho ntlafatsa ho khomarela.
Metswako e Itekanelang: HPMC le HEMC di eketsoa metswakong e iketsang e lekantsoeng ho ntlafatsa phallo le thepa ea ho leka-lekanya. Li-polymer tsena li thusa ho fokotsa ho teteana, ho laola ho monyela metsi le ho fana ka qetello e betere ea bokaholimo. Li boetse li ntlafatsa ho khomarela ha motsoako ho substrate.
Ho kopanya lithaele: HPMC le HEMC li ka sebelisoa bakeng sa ho kopanya lithaele le ho kopanya lithaele. Li sebetsa e le li-rheology modifiers, li ntlafatsa phallo le ho sebetsa ha li-grout. Li-polymer tsena li boetse li fokotsa ho kenella ha metsi, li ntlafatsa ho khomarela le ho ntlafatsa ho hanyetsa mapetso.
Ka kakaretso, HPMC le HEMC li sebelisoa haholo thepa ea kaho ka lebaka la bokhoni ba tsona ba ho ntlafatsa ts'ebetso, ho khomarela, ho boloka metsi le ts'ebetso e akaretsang ea lihlahisoa. Li khothalletsa mekhoa e metle ea kaho ka ho ntlafatsa ho tšoarella le boleng ba likarolo tse fapaneng tsa kaho.
