Karolo ea hydroxypropyl methylcellulose ke efe ka konkreite ea foam

Bophahamo bo fokotsehileng ba boloko ba teko ka har'a hlobo ka mor'a ho bōptjoa bo bontša phello ea hydroxypropyl methylcellulose holim'a botsitso ba molumo oa konkreite e foamed. Ho ka bonoa hore tekanyo ea 0.05% hydroxypropyl methylcellulose ke tekanyo e nepahetseng, 'me ha tekanyo ea hydroxypropylmethylcellulose e le 0.05%, bophahamo ba phokotso bo ntse bo eketseha butle-butle. Tlhahlobo e bontša hore ha hydroxypropyl methylcellulose e loketse, e ka fokotsa ho fokotseha ha molumo oa 'mele o thata ha o ntse o ntlafatsa ho phalla ha slurry. Nakong ea ho thatafala ha slurry, metsi a lula a lahleha. Foam e ka hare e boetse e lula e nyahame, 'me ho khutsufatsoa ha' mele o thata ho ke ke ha qojoa. Sena se etsa hore molumo oa 'mele o thata o se ke oa tsitsa,' me motsoako oa hydroxypropyl methylcellulose ha o fane feela ka 'mele o thata Ha o na le phello e ntle ea ho boloka metsi, empa o boetse o tsitsisa le ho thatafatsa foam ea pele ka litšobotsi tsa slurry harding le hydroxypropyl. filimi ea methylcellulose e thatafatsa ka nako e le 'ngoe, e le ho bapala foam e ntle ea ho tsitsisa le ho fokotsa ho fokotseha ha molumo oa' mele o thata.

Ho tsitsisa foam e thusang

Ha palo ea hydroxypropyl methylcellulose e eketsoa ho 0.5%, ho putlama ho ile ha fokotseha hanyane. Lintlha li bonts'a hore ha litaba tsa hydroxypropyl methylcellulose li sa fete 0.05%, ho eketsoa ha hydroxypropyl methylcellulose ho ka ntlafatsa haholo mokelikeli le viscosity ea slurry ea konkreite e foamed. Ka mor'a hore hydroxypropyl methylcellulose e qhibilihe, filimi e mongobo e tsitsitseng e tsitsitseng e thehoa pakeng tsa likaroloana tse tiileng tsa karolo le likhase tsa khase, tse nang le phello e ntle haholo nakong ea ho kopanya. Slurry ke "bolo" e sa lefelloeng le e ts'oanang, e ntlafatsang ka katleho metsi a slurry e sa tsoa tsoakoa: empa haeba palo ea hydroxypropyl methylcellulose e feta 0.5%, slurry e tla fetoha viscous haholo 'me mokelikeli o tla fokotseha haholo. Leha ho le joalo, 0.05% hydroxypropyl methylcellulose ha e tiise feela ho theoha, empa hape e tsitsisa li-bubble tsa moea, tse loketseng ho eketsa batho.
