Izinzuzo ezibalulekile zezobuchwepheshe nezomnotho ze-ejenti yokungena komoya ezisetshenziswa ngokhonkolo kwezentengiso
Ukuhlanganiswa komoya okubangelwa komoya kungukuhlanganiswa okunamandla okungakhiqiza inani elikhulu lama-bubble amancane, aminyene futhi azinzile lapho kuxutshwa ukhonkolo. Ukuqina okunjengokumelana nesithwathwa nokungapheli. Ukungezwa kwe-ejenti yokungena komoya kukhonkolo wezentengiselwano kungavimbela ama-adsorption wesibili amakhaza ahlakazekile kakhonkolo kukhonkolo futhi athuthukise ukusebenza kwekhonkolo okuthengiswa kokhonkolo wezohwebo. Njengamanje, i-ejenti yokungena komoya ingenye yezinto ezisemqoka ekuhlanganiseni kokhonkolo kwezohwebo (abanye banciphisa amanzi kanye ne-retarder). Emazweni aseJapan nasentshonalanga, cishe akukho kokhonkolo ngaphandle kwe-ejenti yokungena komoya. EJapan, ukhonkolo ngaphandle kwe-ejenti yokungena komoya ibizwa ngokuthi ukhonkolo okhethekile (njengokukhonkolo okuvunyelwe, njll.).
Ukufakwa komoya kuzothinta amandla kakhonkolo, okusho imiphumela yokuhlolwa ngaphansi kwesimo sikakhonkolo kanye nosimende wamanzi. Lapho okuqukethwe komoya kukhuphuka ngo-1%, amandla kakhonkolo azoncishiswa ngo-4% kuya ku-6%, futhi ukungezwa komenzeli wokufaka umoya kuzonciphisa namandla kakhonkolo. Izinga lamanzi landa kakhulu. Kuhlolwe nge-superplastizer esekelwe ku-naphthalisane. Lapho isilinganiso sokhonkolo sokuncipha kwamanzi singama-15.5%, izinga lokuncipha kwamanzi ukhonkolo lifinyelela ngaphezu kwama-20% ngemuva kokungeza inani elincane kakhulu le-ejenti yokungena komoya, okungukuthi, izinga lokuncipha kwamanzi likhuphuka ngo-4.5%. Kuwo wonke ama-1% ukukhuphuka kwezinga lamanzi, amandla ukhonkolo azokwanda ngo-2% kuya ku-4%. Ngakho-ke, inqobo nje uma inani lokufaka umoya
Umenzeli ulawulwa ngokuqinile, hhayi kuphela amandla kakhonkolo ngeke anciphe, kodwa kuzokwanda. Ukulawulwa kokuqukethwe komoya, izivivinyo eziningi zikhombisile ukuthi okuqukethwe komoya kokhonkolo wamandla aphansi kulawulwa ngo-5%, ukhonkolo wamandla aphakathi nendawo alawulwa ngo-4% kuya ku-5%, kanti ukhonkolo wamandla aphezulu alawulwa ngo-3 %, futhi amandla ukhonkolo ngeke ancishiswe. . Ngoba i-ejenti yokungena komoya inemiphumela ehlukene emandleni kakhonkolo anezilinganiso ezihlukile zamanzi.
Uma kucatshangelwa umphumela oncishisiwe wamanzi we-ejenti yokungena emoyeni, lapho ulungiselela ukuhlanganiswa kokhonkolo kwezohwebo, uphuzo olwenziwe ngomama we-ejenti lokunciphisa amanzi kungancishiswa kakhulu, futhi inzuzo yezomnotho iyabonakala.
