Funda malunga neearhente ezisebenzayo zokunciphisa amanzi: i-polycarboxylated vs naphthalene superplastikizer
1. Yintoni i-superplastikizer? Kutheni le nto iyimfuneko kwikhonkrithi?
I-Superplastickibers iphucula ukusebenza kwekhonkrithi kwaye inciphise umyinge wamanzi, obaluleke kakhulu ukufezekisa ulwelo olufunekayo namandla kwiiprojekthi zokwakha zale mihla.
I-2. UNaphthalene Superplaistiber: Ukhetho lwendabuko olufikelelekayo
I-Naphthalene Superplaistivers idla ngokuba yinto entle ngenxa yokungabikho kwabo ngexabiso lendleko zokunyusa amandla ekhonkrithi ngokunciphisa umlinganiselo wamanzi wesamente. Ngaphandle kokufikelelwa, banexesha elifutshane lokugcina umhlaba, banciphise ukusetyenziswa kwabo kwezinye izicelo zanamhlanje.
I-3. I-Polycarbarlex
I-Polycarbants uposplasticylates imela itekhnoloji ephucukileyo ephucula kakhulu iprosisanes kunye namandla. Benza kakuhle kwizicelo eziphezulu zomsebenzi, bebonelela ixesha elide kalwutmber kunye ne-cement yesahlulo esifanelekileyo.
Ukuthelekisa intsebenzo: Ukuncitshiswa kwamanzi kunye nokuqina
Xa uthelekisa intsebenzo ye-Polycarbacyad Enye yezona zinto zibalulekileyo zePCE yireyithi yokuphelisa amanzi aphezulu, enokufikelela kwi-30-55%, ngelixa i-PNS yi-20-25% kuphela. Esi sikhundla siphezulu sokuncitshiswa kwamanzi sinciphisa umxholo wamanzi kwikhonkrithi ngelixa sigcina ubisi olufunwayo, olukhokelela kwikhonkrithi eyomeleleyo, eyomeleleyo ngakumbi.
Ukongeza, i-PCE inezakhono ezigqwesileyo ukuqinisekisa ukuba amasuntswana ethutyana asasazwa ngokulinganayo kuwo wonke umxube wekhonkrithi. Oku kuphucula ulwahlulo kunye nokusebenza, oko kubalulekile ukuthintela ukuqhekeka ngokukhuthaza unyango olufanayo nolwalamano. Ezi mpawu ziluncedo kakhulu kwiiyilo ezintsonkothileyo okanye ezinobuchule ezifuna ulwelo oluphezulu.
I-PCE ikwandisa ixesha lokuqala elisetiweyo, ukubonelela ngokuguquguquka ngakumbi ngokwakhiwa, ngakumbi kwiiprojekthi ezinkulu ezifuna iiyure ezininzi zokusebenza. Esi sisibonelelo esibalulekileyo kumandla aphezulu kunye nezicelo eziphezulu eziphezulu, ezinjenge-CR0 Ikhonkrithi, apho imfuneko yekhonkrithi yokusebenza kakuhle enokumelana nemithwalo enkulu kunye noxinzelelo lubalulekile. Ngokwahlukileyo, uNaphthalene Superplaichie, nangona esebenza ngendleko, azilunganga njenge-PCE ekunciphiseni amanzi okanye adibanise ukusebenza, ukuze i-PCE ithanda iiprojekthi ezinemfuno zokusebenza ezingqongqo.
