Methylcellulose e bapala karolo ea bohlokoa ho thehoeng ha lirafshoa le li-plaster, haholo ho ntlafatsa thepa ea tsona e tlamang. Lits'ebetsong tsa kaho, lirafshoa le lipolasetere ke lisebelisoa tsa mantlha tse sebelisetsoang merero e fapaneng, ho kenyelletsa le masonry, stuccoing, rendering, le mesebetsi ea ho lokisa. Ho eketsoa ha methylcellulose ho metsoako ena ho sebetsa mesebetsi e mengata ea bohlokoa, e tlatsetsang ho sebetsa ka kakaretso le ho tšoarella ha sehlahisoa sa ho qetela.
1. Paballo ea Metsi:
Methylcellulose e sebetsa e le moemeli oa ho boloka metsi ka har'a seretse le li-plaster. Sebopeho sa eona sa hydrophilic se e lumella ho monya le ho boloka metsi ka har'a motsoako, ho thibela ho omisa pele ho nako. Nako ena e telele ea hydration e bohlokoa bakeng sa ho netefatsa pheko e nepahetseng le ho khomarela thepa ho substrate. Ka ho boloka mongobo o nepahetseng, methylcellulose e ntlafatsa ts'ebetso, e lumellang hore ho be bonolo ho sebelisa le ho sebetsana le seretse kapa samente.
2. Matlafatso a Ntlafetseng:
Ho khomarela ka katleho ho bohlokoa bakeng sa ts'ebetso ea nako e telele ea seretse le li-plaster. Methylcellulose e sebetsa e le tlamahano, e etsa maqhama a kopanetsoeng pakeng tsa likaroloana tsa motho ka mong tsa motsoako le bokaholimo ba substrate. Tlamahano ena e bohlokoa bakeng sa ho thibela delamination le ho netefatsa botšepehi ba sebopeho sa thepa e sebelisoang. Ho phaella moo, ho ba teng ha methylcellulose ho khothalletsa ho khomarela hantle ho li-substrates tse fapa-fapaneng, ho akarelletsa le konkreite, masonry, lehong le tšepe, ka tsela eo ho ntlafatsa mekhoa e mengata le ho sebetsa.
3. Momahano e Eketsehileng:
Ntle le ho matlafatsa ho khomarela, methylcellulose e kenya letsoho ho hokahaneng ha seretse le li-plaster. E sebetsa joalo ka setlamo, se kopanyang likaroloana tse kopaneng le likarolo tse ling tsa motsoako. Kopano ena e ntlafatsa matla a kakaretso le botsitso ba thepa, ho fokotsa monyetla oa ho senya, ho fokotseha, le mefuta e meng ea deformation. Ka lebaka leo, methylcellulose e thusa ho etsa lirekere tse matla le tse tšoarellang le li-plaster tse khonang ho mamella matla a ka ntle le maemo a tikoloho.
4. Crack Resistance:
Ho petsoha ke taba e tloaelehileng eo ho thulanoang le eona lits'ebetsong tsa seretse le samente, hangata e bakoang ke lintlha tse kang ho honyela, ho hola ha mocheso, le ho sisinyeha ha meralo. Methylcellulose e thusa ho fokotsa bothata bona ka ho ntlafatsa ho tenyetseha le ho tenyetseha ha thepa. Boteng ba eona bo lumella seretse kapa samente ho amohela metsamao e menyenyane le khatello ea maikutlo ntle le ho robeha, ka hona ho fokotsa kotsi ea ho phatloha le ho ntlafatsa ho tšoarella ha sebopeho ka kakaretso.
5. Ho sebetsa le ho hasana:
Ho eketsoa ha methylcellulose ho matlafatsa ts'ebetso le ho ata ha seretse le li-plaster. Bokhoni ba eona ba ho boloka metsi le ho tlotsa motsoako o thusa ho etsa ts'ebeliso e bonolo le ho fana ka tšireletso e ntle, e leng se etsang hore e be le sephetho se ts'oanang le se khahlisang. Ho feta moo, mokhoa o ntlafetseng oa ho sebetsa o lumella hore ho be bonolo ho bōptjoa, ho bōptjoa le ho qaqisa lintlha, ho nolofalletsa litsebi tsa mesebetsi ea matsoho ho finyella libopeho tse lakatsehang le lipaterone ka mokhoa o nepahetseng haholoanyane.
6. Phokotso ea ho sisinyeha le ho thella:
Ho sisinyeha le ho thella ke mathata a tloaelehileng a kopanang le ona nakong ea ts'ebetso ea lirafshoa tse otlolohileng kapa tse holimo le liplasetere. Methylcellulose e thusa ho rarolla mathata ana ka ho eketsa thepa ea thixotropic ea motsoako. Thixotropy e bua ka phetoho e fetohang ea thepa ho tloha boemong bo kang ba gel ho ea ho boemo ba mokelikeli o eketsehileng tlas'a khatello ea ho kuta, e lumellang hore e phalle habonolo nakong ea kopo empa e boele e fumane viscosity ha e sebelisoa. Ka ho ntlafatsa thixotropy, methylcellulose e thusa ho thibela ho theoha le ho theoha, ho netefatsa ho tšoana le botšepehi ba lera le sebelisitsoeng.
7. Tšebelisano ea Tikoloho:
Methylcellulose e nkoa e le botsoalle ba tikoloho ebile e se chefo, e etsa hore e loketse ho sebelisoa lits'ebetsong tsa kaho moo ts'ebetso le ts'ireletso e leng lintho tse amehang haholo. Ho fapana le litlama tse ling tsa maiketsetso, methylcellulose e ka senyeha habonolo ebile ha e lokolle lik'hemik'hale tse kotsi tikolohong. Tšebeliso ea eona e lumellana le melao-motheo ea mohaho o motala le mekhoa ea kaho e tsitsitseng, e tlatsetsang ho bophelo bo botle ba moea oa ka tlung le ho fokotsa tšusumetso ea tikoloho.
8. Ho lumellana le Li-additives:
Methylcellulose e lumellana le mefuta e mengata ea li-additives tse atisang ho sebelisoa ha ho etsoa seretse le samente, tse kang li-air-entraining agents, li-accelerator, li-retarders le li-pigments. Ho feto-fetoha ha eona ho lumella ho kenyelletsoa ha li-additives tse fapaneng ho fetola thepa e khethehileng ea motsoako, joalo ka ho beha nako, nts'etsopele ea matla, 'mala le sebopeho. Tšebelisano ena e ntlafatsa ho feto-fetoha ha maemo le ho etsoa ha seretse le samente, ho nolofalletsa litharollo tse lokiselitsoeng ho fihlela litlhoko tse khethehileng tsa morero le mekhoa ea ts'ebetso.
methylcellulose e bapala karolo e ngata ho ntlafatsa ts'ebetso, ho tšoarella, le ho sebetsa ha seretse le li-plaster. Bokhoni ba eona ba ho boloka metsi, ho ntlafatsa momahano le momahano, ho hanela ho peperana, ho matlafatsa ts'ebetso, ho fokotsa ho sisinyeha, le ho netefatsa ho lumellana ha tikoloho ho e etsa tlatsetso ea bohlokoa lits'ebetsong tsa kaho. Ka ho kenyelletsa methylcellulose ka har'a seretse le samente, lihahi le litsebi tsa mesebetsi ea matsoho li ka finyella liphello tse phahameng, ho netefatsa nako e telele le botšepehi ba mehaho ea bona.
