Umphumela we-Superplasticizer kanye nomgomo

I-ejenti yokunciphisa amanzi esebenza kahle kakhulu ingathuthukisa kakhulu uketshezi lwe-slurry enyakazayo, ukuze udaka olunamagwebu lufinyelele ukuzilinganisa esikhunjeni, ukunciphisa noma ngisho kungekho isinkwa. Inganciphisa kakhulu ukusetshenziswa kwamanzi ngenkathi igcina ukuwohloka kukakhonkolo, futhi i-ejenti yokunciphisa amanzi ibizwa nangokuthi i-dispersant noma i-plasticizer. Yinhlanganisela esetshenziswa kakhulu.

Indima ye-ejenti yokunciphisa amanzi:

1. Yehlisa amandla esixhumi esibonakalayo esiqinile sezinhlayiya zikasimende

2.Ukunengwa okuqinile

3.Amandla anyanyekayo wendawo

4. Umphumela wokugcoba we-hydration ifilimu

Umgomo we-ejenti yokunciphisa amanzi:

Indawo ethize kasimende imvamisa ingu-350-400m2 / kg, kanye nosayizi wezinhlayiyana ezingaphezu kuka 90% yezinhlayiya zikasimende kububanzi be 7-80 ama-microns, okuyingxenye yezinhlayiya zempushana. Ngohlelo lukasimende lwamanzi, ingaphezulu lezinhlayiya zikasimende kanye nezinhlayiya zikasimende ezinama-hydrated zinendawo epholile futhi ine-hydrophilicity eqinile. Izinhlayiya zikasimende ezinhle zinamandla angaphezulu athile (amandla esibonakalayo aqinile-oketshezi). To reduce the total heat on the surface solid-liquid, izinhlayiya zikasimende ezinhle zivamise ukujiya zibe yi-floc ukuze kuncishiswe amandla esixhumi esibonakalayo sesistimu futhi zenze isistimu i-thermodynamic.. Gcina ukuzinza. Ngesikhathi esifanayo, esigabeni sokuqala usimende hydration, ubuso bezinhlayiya ze-C3A bukhokhiswa kahle, kuyilapho izinhlayiya ze-C3S ne-C2S zishajwa kabi. Ukukhangwa kwe-electrostatic kwamashaji avumayo kanye namabi nawo akhuthaza ukwakheka kwe-flocculation structure yezinhlayiya zikasimende..

Zintathu izindlela zamanzi kukhonkolo: amanzi mahhala angena emanzini kanye namanzi adsorbed. Esikhathini sokuqala sokuxuba usimende, kukhona amanzi amancane ahlanganiswe ngamakhemikhali kanye namanzi adsorbed, futhi amanzi axubile ikakhulukazi akhona ngesimo samanzi amahhala. Nokho, ngenxa yokwakheka kwe-flocculation yezinhlayiya zikasimende, 10% -30% amanzi avulekile azosongwa kuwo, ngaleyo ndlela kunciphisa kakhulu uketshezi lwengxube kakhonkolo. Indima eyinhloko ukubhubhisa isakhiwo se-flocculation yezinhlayiya zikasimende, ligcine lisesimweni sokuhlakazeka, futhi ukhulule amanzi amahhala ephaketheni kanye ne-floc, ngaleyo ndlela kuthuthukisa uketshezi lukakhonkolo olusha.

I-Cie-China.org ingumhlinzeki oholayo wezithasiselo zikakhonkolo wegwebu ohlinzeka nge-ejenti yokugwedla ukhonkolo, superplasticizer,isithuthukisi samandla kakhonkolo wegwebu kukhonkolo ongasindi, Amabhulokhi e-CLC. Uma ufuna si-uperplasticizer, sicela ukhululeke Xhumana nathi.
