Indlela yokusebenza yearhente yokunciphisa amanzi

Ii-agent zokunciphisa amanzi, ezikwaziwa ngokuba zii-plasticizers, zizongezo ezisetyenziswa kwikhonkrithi nakwezinye izinto zesamente ukunciphisa ubungakanani bamanzi afunekayo ukufezekisa ukusebenza okufunwayo kunye namandla. Indlela yokusebenza ye-agent yokunciphisa amanzi inokuchazwa ngomphumo wabo kwiipropati ezibonakalayo zezinto ze-cementitious.

Ii-agent zokunciphisa amanzi zisebenza ngokubhengeza kumphezulu weengqungquthela zesamente kunye nokutshintsha iintlawulo ze-electrostatic kwiinqununu. Oku kunciphisa amandla aphikisayo phakathi kwamaqhekeza, okubavumela ukuba bapakishe kunye ngokuqinileyo. Ngenxa yoko, izithuba ezingenanto phakathi kwamaqhekeza ziyancitshiswa, kwaye amanzi afunekayo ukuzalisa ezo zithuba ayancipha.

Ukusetyenziswa kwee-agent zokunciphisa amanzi kunokuphucula ukusebenza kwekhonkrithi okanye i-cementitious material, okwenza kube lula ukuphatha kunye nokubeka. Oku kubangelwa ukunciphisa i-viscosity yomxube, okuvumela ukuphuculwa kokuhamba kunye nokudibanisa.

Ii-agent zokunciphisa amanzi zingahlelwa kwiindidi ezimbini eziphambili: i-lignosulfonates kunye neepolymers zokwenziwa. I-Lignosulfonates ithathwe kwi-pulp yomthi kwaye isetyenziswa ngokuqhelekileyo kwikhonkrithi yamandla aphantsi ukuya kwimodareyitha. Iipolymers zokwenziwa zenziwe ngeekhemikhali kwaye zinokubonelela ngokuncipha okukhulu kwimfuno yamanzi kunye nokuphuculwa kokusebenza, okwenza ukuba zilungele ukusetyenziswa kwikhonkrithi ephezulu yokusebenza.

Isishwankathelo, indlela yokusebenza ye-agent yokunciphisa amanzi ibandakanya i-adsorption kwi-particle ye-cement kunye nokutshintsha iintlawulo ze-electrostatic kwiinqununu. Oku kunciphisa amandla okuhlambalaza phakathi kwamaqhekeza kwaye kuvumele ukuba bapakishe kunye ngokuqinileyo, ukunciphisa izithuba ezingenanto kunye nokunciphisa umthamo wamanzi afunekayo. Ukusetyenziswa kwee-agent zokunciphisa amanzi kunokuphucula ukusebenza kwekhonkrithi okanye i-cementitious material, okwenza kube lula ukuphatha kunye nokubeka.
