Li-additives tsa Konkreite tse bobebe | Li-Agents tse Foaming tse Phahameng ka ho Fetisisa bakeng sa Konkreite ea Cellular
Mokelikeli oa konkreite o foaming ke motsoako oa metsi, metsoako ea alkaline, le li-surfactants. Setsi sa ho phophoma se sebelisoa ho etsa konkreite e bobebe ea cellular, e tsejoang hape ka hore ke aircrete. Mofuta ona oa konkreite o bobebe ebile o matla haholo. E tšoauoa ka bokhoni ba ho etsa li-bubble tse nyane, e thusang ho dula sebakeng.
Ho hlophisoa ha moemeli oa foaming ho fapana le litšobotsi tse lakatsehang. Ke habohlokoa ho khetha motsoako o sa tloaelehang ho lik'hemik'hale kapa mekhoa ea 'mele. Ho feta moo, motsoako o tlameha ho lumellana le likaroloana tsa samente ho etsa bonnete ba hore moea o koahetsoe ka mokhoa o tsitsitseng..
Motsoako oa lik'hemik'hale oa moemeli oa foaming o kenyelletsa metsi, sodium laurerth succinate, lineralkyl benzene sulfonic acid, le alkyl ether sulfate. Lik'hemik'hale tsena li teng ka har'a mahloriso a seng ka tlase ho 0.04% ka boima ba samente.
Palo ea 40-45% metsi a qhibilihang alkylnaphtliylene sulphonate le 20-25% polyvinyl chloride e phofshoana e teng ka har'a sesebelisoa se phophomang. Metsoako ena e leka-lekanya metsi 'me e etsa hore ho be le porosity e tšoanang ka har'a foam.
Thepa e tlatselletsang ea samente joalo ka slag ea fatše ea granulated blast furnace e ka eketsoa ho ntho e phophomang.. Motsoako ona o fokotsa tšebeliso ea samente mme o eketsa matla a khatello ea foam e felileng.
Ho hlahisa konkreite e foamed ea boleng bo holimo, hoa hlokahala ho boloka tekanyo e sebetsang ea tlhahiso ea ho foaming. Sekhahla se khethoa ke karolo ea motsoako oa foaming le boima ba motsoako. Leha ho le joalo, ke habohlokoa ho hopola hore likarolo tse phahameng tsa moemeli oa foaming ha li eketse thepa e lakatsehang ea konkreite..
