Yini ama-water anciphise amanzi?

Amanzi anciphise amanzi (anjengeLiglosulfonates) uhlobo lokuhlanganiswa okungeziwe kukhonkolo ngesikhathi senqubo yokuxuba. Amanzi anciphise amanzi anganciphisa okuqukethwe kwamanzi ngo-12-30% ngaphandle kokuyekethisa ukusebenziseka kokhonkolo noma amandla okusebenza ngokhonkolo (esivame ukuveza ngokuya ngamandla acindezelwe). Kuneminye imigomo yokunciphiswa kwamanzi, okuyi-superplastifizer, amapulasitiki noma ama-subvucers amanzi aphezulu (HRWR).

Izinhlobo zokunciphisa amanzi ancishisiwe

Kunezinhlobo eziningi zokunciphisa amanzi. Izinkampani zokukhiqiza zinikeza amagama ahlukene kanye nezigaba ezihlukile kulokhu okumangalisa njengama-admixtures afana nabafakazela amanzi, abathengisi, aids, njll.

Ngokuvamile, singakwazi ukuhlukanisa ama-water-anciphise amanzi abe izinhlobo ezintathu ngokuya ngokwakheka kwamakhemikhali (njengasetafuleni 1):

I-Liglosulfonates, i-Hydroxycarboxbylic acid, kanye nama-poldmer ahlanganisiwe.

Iqhaqha livela kuphi?

ILignin iyinto eyinkimbinkimbi emelela cishe i-20% yokwakheka kwezinkuni. Ngesikhathi senqubo yokukhiqizwa kwepulpicu ye-Wood ngokhuni, kwakhiwa utshwala imfucuza njengoMkhiqizo oqukethe inhlanganisela eyinkimbinkimbi yezinto, kufaka phakathi imikhiqizo yokubola ye-lignin kanye ne-callulose, imikhiqizo ehlukahlukene ye-lignin, ama-carbohydrate ahlukahlukene (ushukela) kanye I-sulfurous acid noma i-sulfates yamahhala.

Ukungathathi hlangothi okulandelayo, izinqubo zemvula nezinqubo zokuvusa zikhiqiza uhla lwamandla ezinhlobonhlobo zokuhlanzeka okuhlukahlukene nokwakheka kuya ngezinto eziningi, njenge-alkali yokuvusa, izinga lobudala obusetshenzisiwe, izinga nobudala bokhuni obusetshenzisiwe njengoba I-Pulp Feedstock.

I-Liglosulfonates njengamanzi - anciphise ngokhonkolo

I-Liglosulfonate Superplastimizer Dose imvamisa ngamaphesenti angama-0,25, okungaholela ekunciphiseni kwamanzi okufika kumaphesenti ayi-9 kuye kwayi-12 ku-Cement Okuqukethwe (0.20-0.30%). Njengoba kusetshenziswe emthanjeni ofanele, amandla ukhonkolo athuthukiswa ngu-15-20% uma kuqhathaniswa nokhonkolo wereferensi. Amandla akhule ngamaphesenti angama-20 kuye kwangama-30 ngemuva kwezinsuku ezi-3, ngamaphesenti angu-15-20 ngemuva kwezinsuku eziyi-7, nangesamba esifanayo ngemuva kwezinsuku ezingama-28.

Ngaphandle kokushintsha amanzi, ukhonkolo kungahle kugeleze ngokukhululeka, okwenza kube lula ukusebenza nge (okungukuthi kwanda ukusebenziseka).

Ngokusebenzisa iTonne eyodwa yeLiglosulfonate Superplastimizer Powder In the Conment, ungagcina amathani angama-30- 40 ka usimende ngenkathi ugcina i-slump ekhonkolo efanayo, ukuqina, kanye nereferensi ukhonkolo efanayo.

Esimweni esijwayelekile, ukhonkolo oxutshwe nalolu melango angabambezela ukushisa okuphezulu kwe-hydration ngamahora angaphezu kwamahlanu, nesikhathi sokugcina sikakhonkolo ngaphezulu kwamahora amathathu uma kuqhathaniswa nokhonkolo ophansi kwamathathu ngokuqhathaniswa nokhonkolo. Lokhu kunenzuzo ukwakhiwa kwehlobo, ukuthutha kokhonkolo kwezompahla, kanye nokhonkolo omkhulu.

I-Liglosulfonate Superplastimizer engenela i-Micro-Ancraining ingathuthukisa ukusebenza kokhonkolo ngokuya nge-freeze-thaw engafanele.
