Uhlalutyo lobugcisa oludityanisiweyo:

1. Ukudibanisa imiba ngotywala bukamama

I-agent yokunciphisa amanzi e-Polycarboxylate luhlobo olutsha lwe-agent ephezulu yokunciphisa amanzi. Xa kuthelekiswa neearhente zemveli zokunciphisa amanzi, ine-dispersibility enamandla kwikhonkrithi kwaye inezinga eliphezulu lokunciphisa amanzi. Ukudityaniswa kotywala be-arhente yokunciphisa amanzi kunokuphunyezwa kwinqanaba elithile. Ukulungelelanisa ingxinano yeemveliso zemolekyuli yecala lamatyathanga, ukuthetha ngokubanzi, ukudibanisa phakathi kotywala boomama kunokufikelela iziphumo ezilungileyo. Utywala obungumama ongatshatanga bunokudityaniswa kunye notywala boomama abaninzi ukufezekisa imisebenzi yabo, kodwa kufuneka kuqatshelwe ukuba umgangatho ophezulu, umgangatho ophezulu wee-monomer liquers kufuneka zikhethwe. Ngelo xesha, i-polycarboxylic acid ayinakudityaniswa kunye nezinye ii-agent zokunciphisa amanzi, ezifana ne-naphthalene series kunye ne-aminoxantholate.

2. Ukudibanisa imiba kunye nezinye izithako ezisebenzayo

Kwinkqubo yokwakhiwa kwangempela, ukwenzela ukuxazulula iingxaki ezijongene nokwakhiwa kweprojekthi, kuyimfuneko ukuphucula ukusebenza kwekhonkrithi. Ukuba i-compound yotywala yomama yedwa ayikwazi ukuhlangabezana neemfuno, kulo mzekelo, ezinye izinto ezincinci ezisebenzayo, ezibandakanya i-thickeners, njl., kufuneka zongezwe ukuphucula ukusebenza kwekhonkrithi. . I-retarder inokongezwa kwikhonkrithi, into encinci elungisa i-arhente yokunciphisa amanzi ukuze ivumelane nexesha lokubeka phantsi kweemeko ezahlukeneyo zokushisa. Ukongeza inxalenye ye-retarder kuya kunciphisa ubuninzi be-concrete slump. Ngexesha elifanayo, xa udibanisa i-retarder, kufuneka kuqatshelwe ukuba i-retarder ngokwayo inomphumela wokunciphisa amanzi, kwaye le nto kufuneka iqwalaselwe ngexesha lokudibanisa i-agent yokunciphisa amanzi. Ingxaki yokuvuza kwamanzi kwikhonkrithi ikwaxhaphakile kwiiprojekthi. Kule meko, i-thickeners kunye ne-air-entraining agents zingasetyenziselwa ukuphucula ingxaki, kodwa umxholo womoya wekhonkrithi kufuneka ulawulwe ngokufanelekileyo, ngaphandle koko amandla ekhonkrithi aya kuncitshiswa.
