Lisebelisoa tsa grouting tse sa nyenyefatseng li bohlokoa kahong bakeng sa ho tlatsa likheo le likheo ntle le phetoho e kholo ea molumo, ho netefatsa botsitso ba sebopeho le ho tšoarella. Karolo ea bohlokoa ea lisebelisoa tsena ke Hydroxypropyl Methylcellulose (HPMC), e tsoang ho cellulose ether e ntlafatsang thepa ea grout.
Ntlafatso ea ho boloka metsi
O mong oa melemo ea mantlha ea HPMC ka thepa e sa honyehang ea grouting ke bokhoni ba eona ba ho ntlafatsa haholo ho boloka metsi. HPMC e etsa filimi holim'a likaroloana tsa samente, e thusang ho fokotsa mouoane oa metsi. Metsi ana a bolokiloeng a bohlokoa bakeng sa ts'ebetso ea hydration ea samente, ho netefatsa hore metsi a felletse ebile a lekana. Ka ho boloka mongobo, HPMC e fokotsa kotsi ea ho fokotseha le ho phunyeha, e ka senyang botšepehi ba grout. Ho feta moo, ho bolokoa ha metsi ho ntlafetseng ho eketsa nako ea ho sebetsa ea grout, ho lumella ho sebelisoa hantle le ho qeta.
Mokhoa o Ntlafetseng oa ho sebetsa
HPMC e ntlafatsa ts'ebetso ea lisebelisoa tse sa honyehang tsa grouting, e etsa hore ho be bonolo ho li kopanya, ho li sebelisa le ho li etsa. Lintho tsa eona tse ikhethang tsa rheological li fetola viscosity ea grout, e fana ka motsoako o laolehang le o momahaneng. Viscosity ena e ntseng e eketseha e thusa kabong e tšoanang ea likaroloana tsa samente le li-filler, tse lebisang ho grout e ts'oanang le e boreleli. Ho feta moo, HPMC e fokotsa karohano le ho tsoa mali, ho etsa bonnete ba hore grout e boloka sebopeho se tsitsitseng nakong eohle ea ts'ebeliso ea eona le lits'ebetso tsa ho folisa. Ts'ebetso e ntlafetseng e boetse e fokotsa boiteko ba basebetsi le ho eketsa katleho ea kopo ea grout.
Keketseho ea ho khomarela
Thepa ea ho khomarela ea lisebelisoa tsa grouting tse sa honyehang li matlafatsoa haholo ke HPMC. Sena se bohlokoa haholo lits'ebetsong moo grout e tlamehang ho tlamahana le likaroloana tse fapaneng tse kang konkreite, tšepe kapa masonry. HPMC e ntlafatsa bokhoni ba ho kolobisa grout, e khothalletsa ho kopana hamolemo le substrate le ho eketsa matla a bond. Ho khomarela ho ntlafetseng ho thibela ho arohana le ho etsa bonnete ba hore grout e lula e tiile, e tlatsetsang botsitso le ho tšoarella ha mohaho.
Ho fokotseha ho Fokotseha le ho Petsoha
Ho fokotseha le ho phunyeha ke litaba tse tloaelehileng linthong tsa setso tsa grouting, tse ka lebisang mefokolong ea sebopeho le ho hlōleha. HPMC e bapala karolo ea bohlokoa ho fokotsa mathata ana ka ho tsitsisa ts'ebetso ea hydration le ho boloka maemo a mongobo. Ka ho laola tekanyo ea samente ea metsi le ho fokotsa tahlehelo ea metsi, HPMC e fokotsa kotsi ea ho fokotseha nakong ea phekolo. Botsitso bona bo bohlokoa bakeng sa ho boloka botsitso ba sebopeho sa grout, ho netefatsa hore se tlatsa likheo le likheo hantle ntle le ho holofala kapa ho honyela ha nako e ntse e ea.
Ntlafatso ea ho tšoarella
Ho kenyeletsoa ha HPMC linthong tse sa honyehang tsa grouting ho matlafatsa ts'ebetso ea tsona e tšoarellang ka ho ntlafatsa ho hanyetsa maemo a tikoloho joalo ka ho fetoha ha mocheso, ho fapana ha mongobo le ho pepesehela lik'hemik'hale. HPMC e etsa filimi e sireletsang ka har'a matrix ea grout, e sebetsang e le thibelo khahlanong le likarolo tse ka ntle. Lera lena le sireletsang le thusa ho thibela ho kenella ha lintho tse kotsi, ho fokotsa kotsi ea ho senya le ho senyeha. Ho tšoarella ho matlafalitsoeng ho netefatsa hore grout e boloka ts'ebetso ea eona le sebopeho sa eona ka nako e telele, ho fokotsa litšenyehelo tsa tlhokomelo le ho lelefatsa bophelo ba mohaho.
Hydroxypropyl Methylcellulose (HPMC) e fana ka melemo e mengata ho thepa e sa honyehang ea grouting, e e etsa tlatsetso ea bohlokoa mohahong oa sejoale-joale. Bokhoni ba eona ba ho ntlafatsa ho boloka metsi, ho ntlafatsa ts'ebetso, ho eketsa ho khomarela, ho fokotsa ho fokotseha, le ho ntlafatsa ho tšoarella ho kenya letsoho mosebetsing o akaretsang le ho tšepahala ha li-grouts. Ka ho sebetsana le litaba tse tloaelehileng tse kang shrinkage le cracking, HPMC e tiisa hore lisebelisoa tse sa fokotseheng tsa grouting li fana ka tharollo ea nako e telele, e tsitsitseng le e sebetsang bakeng sa ho tlatsa likheo le likheo lits'ebetsong tse sa tšoaneng tsa kaho. Ha litlhoko tsa kaho li ntse li tsoela pele ho fetoha, karolo ea HPMC ho ntlafatseng lisebelisoa tsa grouting e tla lula e le bohlokoa, ho ts'ehetsa nts'etsopele ea mekhoa ea kaho e tsitsitseng le e tsitsitseng.
