Karolo ea Hydroxypropyl Methylcellulose (HPMC) ho Mortars and Renders
Likarolo tsa seretse le li-renders li bapala karolo ea bohlokoa kahong, ho fana ka sets'oants'o sa sebopeho, ho hanyetsa boemo ba leholimo le boipiletso bo botle meahong. Ho theosa le lilemo, tsoelo-pele ea thepa ea kaho e lebisitse ho nts'etsopele ea li-additives ho ntlafatsa thepa ea seretse le phetolelo. E 'ngoe ea litlatsetso tse joalo tse hlahelletseng ke Hydroxypropyl Methylcellulose (HPMC).
Ho utloisisa HPMC:
Hydroxypropyl Methylcellulose (HPMC)ke ether e seng ea ionic cellulose e nkiloeng ho lipolima tsa tlhaho, haholo-holo selulose. E entsoe ka karabelo ea alkali cellulose ka methyl chloride le propylene oxide. HPMC e sebelisoa haholo liindastering tse fapaneng, ho kenyeletsoa kaho, meriana, lijo le litlolo, ka lebaka la thepa ea eona e fapaneng.
Thepa ea HPMC:
Poloko ea Metsi: HPMC e etsa filimi e tšesaane ha e tsoakoa le metsi, e ntlafatsang matla a ho boloka metsi a liretse le ho fana. Sena se thibela ho omisoa pele ho nako, ho etsa bonnete ba hore lisebelisoa tsa samente li na le metsi a betere le ho matlafatsa ts'ebetso.
Ntlafatso ea Ts'ebetso e Ntlafetseng: Ho eketsoa ha HPMC ho fana ka phello ea ho tlotsa, ho thusa ho hasana le ho sebelisoa ha seretse le liphetolelo. E matlafatsa momahano le ho tsitsisa ha motsoako, e leng se etsang hore ho be le likhahla tse boreleli.
Adhesion: HPMC e ntlafatsa ho khomarela liretse le ho fana ka likaroloana tse fapaneng, tse kang konkreite, litene le majoe. Sena se khothalletsa maqhama a matla, ho fokotsa kotsi ea delamination kapa detachment ka nako.
Nako e Eketsehileng ea ho Bula: Nako ea ho bula e bolela nako eo seretse kapa tlhahiso e lulang e sebetsa pele e beha. HPMC e eketsa nako e bulehileng ka ho liehisa tlhophiso ea pele ea motsoako, ho lumella ts'ebeliso e ntle le ho phethela, haholo mererong e meholo.
Crack Resistance: Ho eketsoa ha HPMC ho ntlafatsa ho tenyetseha le ho tenyetseha ha liretse le ho fana, ho fokotsa monyetla oa ho phatloha ka lebaka la ho honyela kapa ho hola ha mocheso. Sena se ntlafatsa ho tšoarella le nako e telele ea sebopeho.
Melemo ea HPMC ho Mortars and Renders:
Ho lumellana:HPMCe netefatsa ho tšoana ha seretse le ho fana ka metsoako, ho fokotsa mefuta e fapaneng ea thepa e kang matla, ho teteana le ho khomarela. Sena se lebisa ts'ebetsong e tsitsitseng le boleng ho pholletsa le lihlopha tse fapaneng.
Ho feto-fetoha ha maemo: HPMC e ka kenyeletsoa seretseng se fapaneng 'me ea fana ka libopeho, ho kenyeletsoa litsamaiso tse thehiloeng ho samente, tse thehiloeng kalaka le gypsum. E ikamahanya hantle le li-substrates tse fapaneng le maemo a tikoloho, e etsa hore e tšoanelehe bakeng sa mefuta e mengata ea likopo.
Tšireletseho: Liretse le lihlahisoa tse matlafalitsoeng ka HPMC li bonts'a khanyetso e matlafalitsoeng ho maemo a tikoloho joalo ka mongobo, ho fetoha ha mocheso le ho pepeseha ha lik'hemik'hale. Sena se ntlafatsa ho tšoarella ka kakaretso le ho tiea ha sebopeho.
Tšebelisano: HPMC e lumellana le li-additives le li-admixtures tse ling tse atisang ho sebelisoa seretseng le ho fana ka metsoako, joalo ka li-air-entraining agents, plasticizers, le lisebelisoa tsa pozzolanic. Ha e kena-kenane le ts'ebetso ea li-additives tsena, e lumellang liphello tsa synergistic.
Likopo tsa HPMC ho Mortars le Renders:
Liqeto tsa Kantle: Liphetolelo tse ntlafalitsoeng tsa HPMC li atisa ho sebelisoa bakeng sa ho qeta ka ntle, ho fana ka tšireletso ea leholimo le liphahlo tse khabisitsoeng ho li-facade. Liphetolelo tsena li fana ka mokhoa o babatsehang oa ho khomarela, ho tenyetseha, le ho hanyetsa crack, ho ntlafatsa ponahalo le ho tšoarella ha mehaho.
Likhomaretsi tsa Lithaele: HPMC ke karolo ea bohlokoa ea likhomaretsi tsa lithaele, e ntlafatsang matla a tlamahano le ts'ebetso ea seretse sa sekhomaretsi. E etsa bonnete ba ho kolobisa hantle le ho koaheloa ha substrate le ho thibela ho omisoa pele ho nako ea sekhomaretsi.
Litokiso tsa ho Lokisa: Likarolo tse lokisoang tsa HPMC li sebelisoa bakeng sa ho lokisoa, ho hlahisa bocha le ho khutlisetsa meaho ea konkreite e senyehileng. Likarolo tsena li bonts'a ho khomarela hantle ho substrate le ho tsamaellana le konkreite e teng, ho netefatsa tokiso e se nang moeli.
Lijase tsa Skim: Lijase tsa Skim, tse sebelisetsoang ho lekanya le ho bebofatsa libaka tse sa lekaneng, li rua molemo ka ho eketsoa ha HPMC. E fana ka ho tsitsisa ha tranelate ho seaparo sa skim, se lumellang hore ho sebelisoe habonolo le ho finyella qetello e boreleli, e ts'oanang.
Hydroxypropyl Methylcellulose (HPMC)e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso, ts'ebetso, le ho tšoarella ha seretse le lits'ebetso tsa kaho. Lintho tsa eona tse ikhethang, tse kang ho boloka metsi, ts'ebetso e ntlafetseng, ho khomarela, le ho hanyetsa ho phatloha, ho etsa hore e be tlatsetso ea bohlokoa bakeng sa ho finyella lisebelisoa tsa boleng bo phahameng le mehaho e tšoarellang nako e telele. Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, ts'ebeliso ea HPMC e lebelletsoe ho eketseha, ho tsamaisa boqapi le botsitso ho thepa ea moaho.
