Phapang e ka Sehloohong - Additives vs Admixtures

Li-additives le li-admixtures ke likarolo tsa lik'hemik'hale tse kenyelletsoeng lisebelisoa tse ling ho ntlafatsa lik'hemik'hale tsa tsona le tsa 'mele. Le hoja ka bobeli e le likarolo tse kenyelletsoeng ho lisebelisoa tse ling, ho na le phapang pakeng tsa li-additives le li-admixtures ha ho tluoa tabeng ea metsoako ea samente le ea konkreite. Li-additives e ka ba li-additives tsa lijo kapa ntho leha e le efe e 'ngoe e kentsoeng nthong e nyenyane ho ntlafatsa kapa ho e boloka. Li-admixtures, ka lehlakoreng le leng, ke likarolo tse kenyelletsoeng motsoako oa konkreite ha li ntse li kopanya. Phapang e kholo lipakeng tsa li-additives le li-admixtures ke hore li-additives li eketsoa ka samente nakong ea tlhahiso ho fumana thepa e ncha ea samente athe li-admixtures li eketsoa metsoako ea konkreite ha li ntse li kopanya ho fumana thepa e ncha.

Li-additives ke eng

Li-additives ke likarolo tsa lik'hemik'hale tse kentsoeng samenteng nakong ea tlhahiso ho fumana thepa e ncha ea samente. Lisebelisoa tse sebelisoang ha ho etsoa samente ke lime, silica, alumina le iron oxide. Lintho tsena li siloa hore e be phofo e ntle 'me li kopantsoe le ho besoa. Ho futhumala ha motsoako ona hoo e ka bang 1500oC ho tla qala liphetoho tse ngata tsa lik'hemik'hale tse fanang ka lik'hemik'hale tsa ho qetela tsa samente.

E le ho fumana thepa e lakatsehang, li-additives tse fapa-fapaneng li kenngoa ho samente ha ho etsoa.

Li-accelerator
Li-accelerator li eketsoa ho fokotsa nako ea ho lokisa samente le ho potlakisa nts'etsopele ea matla a khatello.

Bahlaseli
Li-retarders li eketsa nako ea ho lokisa samente. Sena se thusa samente hore e be le nako e lekaneng ea ho bea leretse lilibeng tse tebileng.

Li-disperants
Lisebelisoa li eketsoa ho fokotsa viscosity ea seretse sa samente le ho netefatsa ho tlosoa ha seretse hantle nakong ea ho beoa.

Liemeli tsa Tahlehelo ea Mokelikeli
Lisebelisoa tsa ho laola tahlehelo ea metsi li laola tahlehelo ea metsi ho tloha samente ho ea ho sebopeho.

Li-accelerator tse ling tse kentsoeng samenteng ke calcium chloride (CaCl2), sodium chloride (NaCl), metsi a leoatle le potassium chloride (KCl).

Li-Admixtures ke eng
Li-admixtures ke likarolo tsa lik'hemik'hale tse kenyelletsoang metsoako ea konkreite ha li ntse li kopanya ho fumana thepa e ncha. Li-admixtures ke likarolo tsa konkreite ntle le samente, metsi le li-aggregates. Li-admixtures li kenngoa ka samente hang-hang pele kapa nakong ea ho kopanya motsoako oa konkreite.

Li-admixtures li eketsoa ho:

-E kenya moea ka boomo
- Fokotsa tlhoko ea metsi
-Eketsa bokhoni ba ho sebetsa
- Fetola nako ea ho phomola
- Fetola matla

Ho na le mefuta e fapaneng ea metsoako e thathamisitsoeng ka tlase ka mehlala e meng.

Metsoako ea ho kenya moea - letsoai la li-resin tsa patsi, li-detergents tse ling, letsoai la li-acids tsa petroleum.
Lisebelisoa tsa polasetiki
Metsoako e fokotsang metsi - lignosulfonates, hydroxylated carboxylic acid, joalo-joalo.
Ho potlakisa metsoako - calcium chloride, sodium thiocyanate, joalo-joalo.
Metsoako ea morao-rao - lignin, borax, tsoekere, joalo-joalo.
Corrosion inhibitors, joalo-joalo.

Tlhaloso
Li-additives: Li-additives ke likarolo tsa lik'hemik'hale tse kentsoeng samenteng nakong ea tlhahiso ho fumana thepa e ncha ea samente.

Li-admixtures: Li-admixtures ke likarolo tsa lik'hemik'hale tse kenyelletsoang metsoako ea konkreite ha li ntse li kopanya ho fumana thepa e ncha.

Lisebelisoa tse so ntlafatsoe
Li-additives: Li-additives li kenngoa ho samente.

Li-admixtures: Li-admixtures li kenngoa ka konkreite.

Keketso
Li-additives: Li-additives li kenngoa ho samente ha ho etsoa.

Li-admixtures: Li-admixtures li kenngoa ka konkreite pele kapa nakong ea ho kopanya.

Mefuta e fapaneng
Li-additives: Li-additives tse fapaneng li khetholloa e le li-accelerator, li-retarders, dispersants, li-agent tse laolang tahlehelo ea metsi, joalo-joalo.

Li-admixtures: Li-admixtures tse fapaneng li khetholloa e le li-admixtures tse bolokang moea, li-plasticizers, li-admixtures tse fokotsang metsi, joalo-joalo.

Qetello
Li-additives li kenngoa ho samente ha ho etsoa tlhahiso. Li-admixtures li kenngoa motsoako oa konkreite pele kapa nakong ea ho kopanya. Phapang e kholo lipakeng tsa li-additives le li-admixtures ke hore li-additives li eketsoa ka samente nakong ea tlhahiso ho fumana thepa e ncha ea samente athe li-admixtures li eketsoa metsoako ea konkreite ha li ntse li kopanya ho fumana thepa e ncha.
