Li-additives tsa Konkreite tse bobebe | Li-Agents tse Foaming tse Phahameng ka ho Fetisisa bakeng sa Konkreite ea Cellular
Konkreite ea foam is foamed by the foaming system of the foaming machine, and the foaming agent is fully foamed mechanically, and the foam and the cement slurry are uniformly mixed, and then casted by the pumping system of the foaming machine, and the natural curing station is adopted.
Compared with physical foaming cement, chemical foaming cement does not need to use a foaming agent, and its foaming is rapid, the efficiency is high, the foam is rich, and the foam stability is good. Ho feta moo, by adjusting the amount of foaming agent and the external environment, it is easy to adjust the amount of bubble generation and the size of the bubble, and produce products of different specifications, making it possible to produce low-weight products.
Mokhoa oa ho foamisa ka lik'hemik'hale o sebelisa reagent ea lik'hemik'hale ho itšoara ka lik'hemik'hale ka har'a slurry ho etsa khase, ka tsela eo ho hlahisa konkreite e foamed.
Kaha lik'hemik'hale tse ka hare tsa lik'hemik'hale li thata ho li hlokomela ebile li thata ho li laola, senotlolo sa ho phophoma ha lik'hemik'hale ke ho laola sekhahla sa karabelo ea lik'hemik'hale le sekhahla sa ho tiea ha slurry ho fihlela tekano e matla lipakeng tsa sebopeho sa khase le ho thatafala ha condensation..
Li-reagents tsa lik'hemik'hale tse sebetsang hona joale ho lokisoa ha konkreite ea foam li: khalsiamo carbide, phofo ea aluminium, letsoai la ammonium, hydrogen peroxide, le tse ling tse joalo.
Calcium hydroxide le acetylene ke phello ea karabelo ea calcium carbide ka metsi. Leha ho le joalo, ts'ebetso ea karabelo e matla haholo, 'me sekhahla sa tlhahiso ea khase se potlakile haholo ho feta lebelo la ho thatafatsa seretse, e le hore sebopeho sa li-bubble se se ke sa tsitsa ka ho lekaneng hore se ka tšela seretse ka nako e khuts'oane., ho etsa palo e kgolo ya mekoti e sa tsitsang ka hodimo.
Acetylene ke khase e tukang le ho phatloha, kahoo calcium carbide ha e loketse ho sebelisoa e le ntho e fokang.
Molao-motheo o ka sehloohong oa ho phophoma ha phofo ea aluminium ke hore phofo ea aluminium e kopana le metsi ka har'a slurry tlas'a tikoloho ea alkaline ho lokolla hydrogen..
Li-pores li thehoa ka ho atolosoa ha hydrogen ka har'a slurry. Leha ho le joalo, palo ea khase e hlahisoang e nyane, 'me e sebelisoa haholo bakeng sa konkreite e foamed e phahameng haholo.
Letsoai la ammonium le senyeha tikolohong ea alkaline ea konkreite ho hlahisa khase ea ammonia, mme sekhahla sa karabelo se ntse se sa lekana le haeba mocheso o phahamisitsoe.Ka hona, ntho e butsoelang letsoai la ammonium ha e khone ho khotsofatsa tlhoko ea ho phophoma ka lik'hemik'hale.
Hydrogen peroxide e ka tšeloa hape ka lisebelisoa tse ling tsa lik'hemik'hale ho fumana O2, 'me sekhahla sa karabelo le sekhahla sa ho tiea ha seretse se ka ba se leka-lekaneng, 'me phello e phophomang e ntle.
Hydrogen peroxide e na le phello e ntle joalo ka moemeli oa phoofo ea lik'hemik'hale, mme sekhahla sa tlhahiso ea khase se laoloa ka ho laola mocheso oa metsi, boemo ba hydrogen peroxide, le bokaalo ba ho kenya letsoho.
Hydrogen peroxide e hasanngoa habonolo ka slurry, le tse hlahisitsoeng 02 e na le matla a khoheli a khethehileng ho feta khase e hlahisoang ke lintho tse ling tse fokang, 'me e ka ba foamed ka mokhoa o ts'oanang le ka tatellano ho tloha tlase ho ea holimo. Ka hona, hydrogen peroxide ke moemeli ea loketseng oa ho foka.
Cie-China.org ke mofani ea ka sehloohong oa li-additives tsa konkreite ea foam e fanang ka konkreite e foqohang, superplasticizer,foam konkreite e matlafatsang bakeng sa konkreite e bobebe, Li-block tsa CLC. Haeba u batla ntho e phophomang, ka kopo ikutloe u lokolohile ho iteanye le rona.
