Li-additives tsa Konkreite tse bobebe | Li-Agents tse Foaming tse Phahameng ka ho Fetisisa bakeng sa Konkreite ea Cellular
protheine e thehiloeng foaming agent ke motsoako oa lik'hemik'hale o thusang ho etsoa ha foam joalo ka ntho e surfactant kapa e fokang.
Li-foaming agents li sebelisoa ka li-detergent tse ngata, sesepa le dihlahiswa tsa ho hlwekisa ho qhala dipudula tsa moya sebakeng se metsi kapa se tiileng. Setsi se setle sa ho phophoma se na le phello e khahlang ea bareki mme se ka ntlafatsa ts'ebetso ea ho hlatsoetsa liaparo, ho hlatsoa lijana, shampoo ea moriri, ho kuta, le litlolo tsa meno.
Thepa e phokang ea liprotheine tse sebelisoang mekhoeng ena e fetoloa ka hydrolysis le acylation kapa phetoho ea lik'hemik'hale ka succinic anhydride., mafura acid kapa metsoako e meng. Liphetoho li ka ama thepa ea protheine ho kenyelletsa le foamability, tsitsipano e kahodimo, le botsitso ba foam.
A protheine e thehiloeng foaming agent hangata e entsoe ka sehlahisoa sa phoofolo se kang mali, lesapo kapa nama. Lihlahisoa tsena li na le protheine e ngata e li lumellang hore li kenelle tšebetsong ea hydralization, e eketsang matla a konkreite e foamed.
Likaroloana tsena tsa protheine ea hydrate li na le sebopeho se rarahaneng sa lik'hemik'hale, e thusang ho ntlafatsa hydration ea samente mme ka hona e fella ka matla a matle a mochini a konkreite e foamed..
Khatello e ka holimo ea protheine ea hydrolyzed e ka fokotsoa ho 28 mN/m, e tlase haholo hofeta mefuta e meng ya disebediswa tse phokang makweba. Sena se fokotsa mosebetsi o hlokahalang ho theha foam le ho ntlafatsa botsitso ba eona ba colloidal ka ho thibela ho kopana ha li-bubble..
Elasticity ea konkreite ea cellular e hlahisoang ke ho protheine e thehiloeng foaming agent e phahame, e etsang hore e be boemong bo loketseng bakeng sa tshebediso ya ditshelo tse tebileng tsa lifti tse le nngwe. Konkreite ena e foamed le eona ha e khonehe, ho etsa hore e mamelle ho petsoha le ho senyeha.
