1. Iimpawu zokusebenza kwe-polycarboxylate water reducer

I-Polycarboxylate water reducer luhlobo olutsha lwe-high-performance water reducer eyenziwe ngokwazisa amaqela amaninzi asebenzayo ane-polyether kunye ne-acrylic acid njenge-main chain. Ulwakhiwo lwayo lwe-molecular lwenziwe ngamaqela e-main chain adsorption kunye namaqela e-side chain steric victory, anomgangatho ophezulu woyilo kunye nokusebenza. Xa kuthelekiswa ne-naphthalene yendabuko okanye i-aliphatic water reducers, i-polycarboxylate water reducers inezi nzuzo zilandelayo ezibalulekileyo:

Izinga eliphezulu lokunciphisa amanzi: I-Polycarboxylate water reducer inokufikelela kwizinga lokunciphisa amanzi elingaphezulu kwama-20% ngedosi ephantsi, nto leyo enciphisa ngempumelelo umlinganiselo wamanzi nesamente kwikhonkrithi, ngaloo ndlela iphucula amandla ayo.

Ukusasazeka kakuhle kunye nokugcinwa kokuwa: Ulwakhiwo lwayo lweemolekyuli lunokwenza umaleko ozinzileyo wokufunxa phezu komphezulu weenxalenye zesamente, lunciphise ukutsalana phakathi kweenxalenye, kwaye lugcine ukunyibilika okuhle.

Ukulahleka okuphantsi kokuwa: Ngokulungisa ubude kunye noxinano lweketanga elisecaleni kwisakhiwo semolekyuli, ukusebenza kokugcinwa kokuwa kwekhonkrithi kunokuphuculwa kakhulu ukuhlangabezana neemfuno zokwakha ixesha elide.

Ukuhambelana okuhle: I-Polycarboxylate water reducer iyakwazi ukuziqhelanisa neentlobo ezahlukeneyo zesamente kunye ne-mineral admixtures (ezifana nothuthu oluphuma kwimpukane, umgubo we-slag, i-silica fume), nto leyo enceda ekuyilweni kakuhle kwenkqubo yekhonkrithi edibeneyo esebenza kakhulu.

Iluhlaza kwaye inobuhlobo nokusingqongileyo: Inkqubo yayo yokwenziwa inobuhlobo nokusingqongileyo, inemveliso ezimbalwa eziphumayo, kwaye ihlangabezana neemfuno zophuhliso oluzinzileyo.

2. Iimfuno ezisisiseko zekhonkrithi enamandla aphezulu

Ikhonkrithi enamandla aphezulu idla ngokubhekisa kwikhonkrithi enamandla okuxinana kwe-cubic ye-C60 nangaphezulu. Ukuze kufezekiswe amandla aphezulu, umlinganiselo wamanzi nesamente kufuneka uncitshiswe ngelixa kuqinisekiswa ukusebenza kakuhle kolwakhiwo (njengokumpompa, ukunyibilika) kunye nokuqina. Ngenxa yesi sizathu, kuyimfuneko ukusebenzisa izixhobo zokunciphisa amanzi ezisebenzayo ukuphucula ukusebenza kwekhonkrithi, kwaye izixhobo zokunciphisa amanzi ze-polycarboxylate zezona zilungileyo zokufezekisa le njongo.
