HPMC (Hydroxypropyl Methyl Cellulose) le HEMC (Hydroxy Ethyl Methyl Cellulose) ke li-cellulose ethers tse atisang ho sebelisoa thepa ea kaho ka lebaka la thepa ea tsona e ikhethang.Ke li-polymers tse qhibilihang ka metsing tse nkiloeng ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela.HPMC le HEMC li sebelisoa e le litlatsetso lihlahisoa tse fapaneng tsa kaho ho ntlafatsa thepa ea tsona le ho ntlafatsa ts'ebetso.
Tse latelang ke tse ling tsa ts'ebeliso ea HPMC le HEMC thepa ea kaho:
Likhomaretsi tsa Lithaele: HPMC le HEMC hangata li eketsoa ho li-adhesives tsa lithaele ho ntlafatsa ts'ebetso le matla a tlamo.Li-polymer tsena li sebetsa e le li-thickeners, li fana ka nako e ntle ea ho bula (hore na sekhomaretsi se lula se sebelisoa halelele hakae) le ho fokotsa ho putlama ha lithaele.Li boetse li matlafatsa sekhomaretsi ho li-substrates tse fapaneng.
Litoeba tsa Cementitious: HPMC le HEMC li sebelisoa liretseng tsa samente tse kang lipolasetere, lipolasetere le litsamaiso tsa ho qetela tsa ho kenella ka ntle (EIFS).Li-polymer tsena li ntlafatsa ts'ebetso ea seretse, ho etsa hore ho be bonolo ho jala le ho sebelisa.Li boetse li ntlafatsa momahano, li fokotsa ho monya ha metsi le ho ntlafatsa ho khomarela liretse ho li-substrates tse fapaneng.
Lihlahisoa tse thehiloeng ho Gypsum: HPMC le HEMC li sebelisoa linthong tse entsoeng ka gypsum tse kang gypsum plasters, metsoako e kopantsoeng le liphahlo tse ikemetseng tsa ho ikemela.Li sebetsa e le lisebelisoa tsa ho boloka metsi, ho ntlafatsa ts'ebetso le ho lelefatsa nako ea ho beha thepa.Li-polymer tsena li boetse li ntlafatsa ho hanyetsa ha crack, ho fokotsa ho honyela le ho ntlafatsa ho khomarela.
Metsoako ea Boithaopo: HPMC le HEMC li eketsoa ho metsoako ea ho ikemela ho ntlafatsa phallo le thepa ea boemo.Li-polymer tsena li thusa ho fokotsa viscosity, ho laola ho monya ha metsi le ho fana ka pheletso e ntle ea bokaholimo.Li boetse li ntlafatsa ho khomarela motsoako ho substrate.
Grouting: HPMC le HEMC li ka sebelisoa bakeng sa ho kopanya lithaele le masonry.Li sebetsa e le liphetoho tsa rheology, ho ntlafatsa phallo le ho sebetsa ha li-grouts.Li-polymer tsena li boetse li fokotsa ho kenella ha metsi, li ntlafatsa ho khomarela le ho matlafatsa ho hanyetsa ha mapheo.
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 ea lihlahisoa ka kakaretso.Ba khothalletsa mekhoa e metle ea ho haha ka ho ntlafatsa ho tšoarella le boleng ba likarolo tse fapaneng tsa mohaho.
