Lilemong tse 'maloa tse fetileng, indasteri ea kaho e bile le kholo le nts'etsopele e kholo. Sena se entse hore ho be le tlhokahalo ea ntlafatso ea li-admixtures le li-additives tsa morao-rao. Li-additives le li-admixtures bakeng sa konkreite ke lintho tsa lik'hemik'hale tse kenyelletsoeng konkreite ho ntlafatsa thepa ea eona ea 'mele le ea lik'hemik'hale. Likarolo tsena li emela lihlahisoa tse ngata tse nang le mefuta e fapaneng ea lik'hemik'hale.
Phapang e kholo pakeng tsa li-admixtures le li-additives ke mekhahlelo eo lintho li kenngoa ka konkreite kapa samente. Li-additives li eketsoa ts'ebetsong ea ho etsa samente, ha ho eketsoa ha metsoako ho etsoa ha ho etsoa metsoako ea konkreite.
Li-Additives ke Eng?
Li-additives li kenngoa ho samente nakong ea tlhahiso ho ntlafatsa thepa ea eona. Ka tloaelo, lisebelisoa tse tala tse amehang tlhahisong ea samente li kenyelletsa alumina, lime, iron oxide le silika. Ka mor'a ho kopanya, lisebelisoa li futhumatsoa hoo e ka bang 1500 ℃ ho lumella samente ho finyella thepa ea eona ea ho qetela ea lik'hemik'hale.
Li-Admixtures ke Eng?
Li-admixtures bakeng sa konkreite e ka ba tsa mefuta e 'meli, metsoako ea organic le inorganic. Li-multifunctional admixtures ke tse fetolang thepa e fetang e le 'ngoe ea' mele kapa ea lik'hemik'hale tsa motsoako oa konkreite. Ho na le mefuta e mengata ea li-admixtures tse fumanehang bakeng sa ho fetola likarolo tse fapaneng tsa konkreite. Li-admixtures li ka aroloa ka:
Metsoako e Fokotsang Metsi
Tsena ke metsoako e sebetsang e le li-plasticizers, tse fokotsang metsi a motsoako oa konkreite ka hoo e ka bang 5% ntle le ho fetola ho lumellana ha eona. Metsoako e fokotsang metsi hangata ke li-polycyclic derivatives kapa phosphates. Ha li eketsoa, metsoako ena e eketsa matla a khatello ea motsoako oa konkreite ka ho etsa hore e be polasetiki e ngata. Mofuta ona oa motsoako o atisa ho sebelisoa ka konkreite ea fatše le ea litsela.
Lisebelisoa tsa Metsi a Phahameng a Phahameng
Tsena ke li-superplasticizers, haholo-holo metsoako ea konkreite ea polymer e fokotsang metsi ka hoo e ka bang 40%. Ka li-admixtures tsena, porosity ea motsoako e fokotseha, ka hona e ntlafatsa matla le ho tšoarella ha eona. Metsoako ena hangata e sebelisoa bakeng sa ho itlama le ho fafatsa konkreite.
Ho Potlakisa Metsoako
Hangata konkreite e nka nako ho fetoha ho tloha ho polasetiki ho ea boemong bo thata. Polyethylene glycols, chloride, nitrate, le metal fluoride hangata li sebelisoa ho etsa mefuta ena ea metsoako. Lintho tsena li ka kenyelletsoa motsoako oa konkreite ho khutsufatsa nako eo e e nkang ho kopanya le ho beha.
Metsoako e Kenyelletsang Moea
Metsoako ena e sebelisoa ho etsa metsoako ea konkreite e kentsoeng moeeng. Li etsa hore ho kenngoe lipululana tsa moea ka har'a motsoako oa konkreite ka hona ho ntlafatsa thepa e kang ho tšoarella le matla ka ho fetola ho qhibiliha ha samente.
Li-admixtures tsa morao-rao
Ho fapana le ho potlakisa li-admixtures tse khutsufatsang tlamahano le maemo, li-admixtures tsa morao-rao li eketsa nako eo konkreite e e nkang ho e beha. Metsoako e joalo ha e fetole karo-karolelano ea samente ea metsi empa e sebelisa li-oxide tsa tšepe le tsoekere ho sitisa mokhoa oa ho tlama.
Li-additives le li-admixtures tsa konkreite hajoale ke sehlopha sa lihlahisoa tse sebetsang hantle ka ho fetisisa tsa lik'hemik'hale tsa kaho. Ho Jufu Chemtech, re sebetsa le lik'hamphani tse kopanyang tsa lehae le tsa machaba ho netefatsa hore bareki ba rona ba fumana lihlahisoa tse ntle ka ho fetisisa bakeng sa mesebetsi ea bona ea kaho. Etela sebaka sa rona sa Marang-rang ho bona le ho reka litlatsetso tsa konkreite tse sebetsang hantle le tse tšepahalang lefatšeng ka bophara.(https://www.jufuchemtech.com/)
