Ka seretse sa konkreite, ho fihlela matla a ho qetela, samente e tlameha ho ba le metsi ka botlalo.Haholo-holo kahong ea lehlabula, seretse sa konkreite se lahleheloa ke metsi ka potlako, 'me litekanyo tsa hydration e feletseng li sebelisetsoa ho boloka le ho fafatsa metsi.Ho senyeha ha lisebelisoa le ts'ebetso e sa thabiseng, senotlolo ke hore metsi a holim'a metsi feela, 'me metsi a ka hare a ntse a sa fella, kahoo tharollo ea bothata bona ke ho eketsa hydroxypropyl methylcellulose kapa methylcellulose ho konkreite ea seretse, Tlhaloso ea viscosity e pakeng tsa 20000-60000cps, chelete ea tlatsetso e ka bang 2 ‰–3 ‰, 'me sekhahla sa ho boloka metsi se ka eketseha ho feta 85%.Mokhoa oa ho sebelisoa ka konkreite ea seretse ke ho eketsa metsi ka mor'a hore phofo e omeletseng e kopane ka ho lekana.
4. Ka plastering gypsum, bonding gypsum, caulking gypsum
Ka tsoelo-pele e potlakileng ea indasteri ea kaho, tlhokahalo ea batho ea thepa e ncha ea mohaho le eona e ntse e eketseha letsatsi le letsatsi.Ka lebaka la keketseho ea tlhokomeliso ea batho mabapi le ts'ireletso ea tikoloho le ntlafatso e tsoelang pele ea katleho ea kaho, lihlahisoa tsa gypsum tsa samente li tsoetse pele ka potlako.Hajoale, lihlahisoa tse atileng haholo tsa gypsum ke gypsum ea ho pola, gypsum e tlanngoeng, gypsum e kentsoeng, le sekhomaretsi sa lithaele.
Plastering gypsum ke thepa ea boleng bo holimo ea ho lipola mabota le siling.Sebaka sa lebota se entsoeng ka eona se setle ebile se boreleli, ha se theohe phofo, se tlamahane ka thata ho setsi, ha se na ho phunyeha le ho oa, 'me se na le mosebetsi o thibelang mollo;bonded gypsum ke mofuta o mocha oa sekhomaretsi sa boto ea leseli ke thepa e khomarelang e entsoeng ka gypsum e le thepa ea motheo le ho eketsa li-additives tse fapaneng.E loketse ho kopanya pakeng tsa lisebelisoa tse sa tšoaneng tsa lerako la mohaho.Ha e na chefo, ha e na tatso, Likarolo tse kang matla a pele, ho beha ka potlako, le ho tlamahanngoa ho tiileng, ke lisebelisoa tse tšehetsang liphanele tsa mohaho le mohaho oa li-block;gypsum caulking agent ke ho tlatsa lekhalo pakeng tsa liphanele tsa gypsum le ho lokisa marako le mapetsong.
Lihlahisoa tsena tsa gypsum li na le letoto la mesebetsi e fapaneng.Ntle le karolo ea gypsum le li-fillers tse amanang le tsona, taba ea bohlokoa ke hore li-additives tse ekelitsoeng tsa cellulose ether li bapala karolo e ka sehloohong.Hobane gypsum e arotsoe ka gypsum ea anhydrous le gypsum ea hemihydrate, gypsum e fapaneng e na le liphello tse fapaneng mosebetsing oa sehlahisoa, kahoo ho teteaneng, ho boloka metsi le ho lieha ho etsa qeto ea boleng ba thepa ea mohaho oa gypsum.Bothata bo tloaelehileng ba lisebelisoa tsena ke ho koala le ho phunyeha, 'me matla a pele a ke ke a finyelloa.Ho rarolla bothata bona, ke ho khetha mofuta oa selulose le mokhoa oa tšebeliso ea motsoako oa retarder.Tabeng ena, methyl kapa hydroxypropyl methyl 30000 hangata e khethoa.-60000cps, chelete e eketsehileng e pakeng tsa 1.5 ‰–2 ‰, selulose e sebelisoa haholo-holo bakeng sa ho boloka metsi le ho fokotsa lubrication.
Leha ho le joalo, ho ke ke ha khoneha ho itšetleha ka cellulose ether e le retarder, 'me hoa hlokahala ho eketsa retarder ea citric acid ho kopanya le ho sebelisa ntle le ho ama matla a pele.
Ho boloka metsi ka kakaretso ho bolela hore na metsi a tla lahleha hakae ka tlhaho ntle le ho monngoa ha metsi ka ntle.Haeba lerako le omme haholo, ho monya metsi le mouoane oa tlhaho holim'a metsi ho tla etsa hore thepa e lahleheloe ke metsi ka potlako, 'me ho phunyeha le ho phunyeha ho tla etsahala.
Mokhoa ona oa tšebeliso o kopantsoe le phofo e omileng.Haeba u lokisetsa tharollo, ka kopo sheba mokhoa oa ho lokisetsa tharollo.
5. Seretse se sireletsang mocheso
Seretse sa insulation ke mofuta o mocha oa thepa ea ka hare ea lebota sebakeng se ka leboea.Ke thepa ea lebota e entsoeng ka thepa ea ho kenya letsoho, seretse le binder.Tabeng ena, cellulose e phetha karolo ea bohlokoa ho tlamahaneng le ho eketsa matla.Ka kakaretso khetha methyl cellulose e nang le viscosity e phahameng (hoo e ka bang 10000eps), tekanyo e tloaelehileng e pakeng tsa 2 ‰ -3 ‰), 'me mokhoa oa ho sebelisa ke ho kopanya phofo e omileng.
6. Moemeli oa li-interface
Sekhomaretsi sa lithaele se lokela ho ba ka holimo ho 60,000cps, 'me se lokela ho sebelisoa e le motenya ka har'a moemeli oa li-interface, se ka ntlafatsang matla a thata le matla a khahlanong le motsu.
