Isicelo soMsebenzi wokuNciphisa Amanzi oPhezulu oPhezulu

1. Ulwakhiwo lweMolekyuli

I-arhente yokunciphisa amanzi e-polycarboxylate enoxinaniso lwetyathanga elisecaleni elingu-≥1.2 nge-nm² nganye ikhethiwe. Impembelelo yayo yokuthintela i-steric inokunciphisa umonakalo we-adsorption layer obangelwa ukushisa okuphezulu. Xa kudityaniswe nge 30% fly uthuthu admixture, izinga lokunciphisa amanzi inokufikelela 35% -40%, kunye neyure enye ilahleko ukuwohloka ngaphantsi kwe-10%. Eli cala liphezulu loxinaniso lwe-polycarboxylate iarhente yokunciphisa amanzi yenza umaleko oshinyeneyo we-adsorption kumphezulu wamasuntswana esamente, ebonelela nge-steric repulsion eyomeleleyo, evumela amasuntswana esamente ukuba agcine imeko esasazeke kakuhle nakwindawo ezinobushushu obuphezulu. Ngaphaya koko, ukongezwa kothuthu lwempukane akunciphisi kuphela ukusetyenziswa kwesamente kwaye kwehlisa ubushushu be-hydration, kodwa kukwadala isiphumo se-synergistic kunye nearhente yokunciphisa amanzi, ngakumbi ukuphucula ukusebenza kunye nokuqina kwekhonkrithi.

2. I-Slump-Preserving Synergistic TechnologyUkuqaliswa kwe-methyl allyl polyoxyethylene ether monomer kudala i-dimensional network structure. Kwiindawo ezifaniswayo kwi-50 ° C, idibaniswe necandelo lokunciphisa, ukwandiswa kwekhonkrithi kunokugcinwa ngaphezu kwe-650mm imizuzu eyi-120, ukuhlangabezana neemfuno zokupompa izakhiwo eziphakamileyo eziphezulu. Ukuqaliswa kwe-methyl allyl polyoxyethylene ether monomers iguqula i-molecular structure ye-polycarboxylate superplasticizer, yenza isakhiwo senethiwekhi esine-dimensional-dimensional eyandisa amandla ayo okudibanisa kunye nokusabalalisa amaqhekeza e-samente. Kwiindawo eziphezulu zokushisa, esi sakhiwo sichasa ngokufanelekileyo ukuphazamiseka kwimveliso ye-samente ye-samente, ukugcina umbane kunye nokuchithwa kwekhonkrithi. Xa isetyenziswe ngokubambisana namacandelo okubuyiswa, inokulibazisa ngaxeshanye i-cement hydration kunye nokugcina i-slump, ihlangabezana neemfuno zokwakhiwa kwekhonkrithi ephezulu, njengokumpompa kwe-ultra-high-rise.
