Ukuhlaziywa kobuchwepheshe obuhlanganisiwe:

1. Izinkinga ezihlanganisa notshwala bamama

I-ejenti ye-polycarboxylate yamanzi iwuhlobo olusha lwe-ejenti yokunciphisa amanzi ephezulu. Uma kuqhathaniswa nama-ejenti ancishisiwe amanzi endabuko, kunokwehluleka okunamandla ngokhonkolo futhi kunesilinganiso esiphezulu sokunciphisa amanzi. Ukuhlanganiswa kotshwala be-ejenti oncishisiwe amanzi kungatholakala ngezinga elithile. Ukulungisa ubuningi bamaketanga aseceleni komkhiqizo, ngokuvamile ukukhuluma, ukuhlanganisa phakathi kotshwala bamama kungathola imiphumela emihle. Utshwala obuyedwa bomama bungahlanganiswa ngotshwala obuningi bamama ukufeza imisebenzi yalo, kepha kufanele kuqashelwe ukuthi iziphuzo ze-monomer ezisezingeni eliphakeme, zisebenza kakhulu kudingeka zikhethwe. Ngasikhathi sinye, i-polycarboxylic acid ayinakuhlanganiswa namanye ama-ejenti ancishisiwe amanzi, anjengochungechunge lwe-naphthalantholate.

2. Izinkinga ezihlanganisa ezinye izithako ezisebenzayo

Enqubweni yokwakha uqobo, ukuze kuxazululwe izinkinga ezabhekene nokwakhiwa kwephrojekthi, kuyadingeka ukuthuthukisa ukusebenza kokhonkolo. Uma umama utshwala elodwa engenakuhlangabezana nezidingo, kulokhu, ezinye izinto ezincane ezisebenzayo, kufaka phakathi izinhlanzi, njll., Kudingeka ukuthi zengezwe ukwenza ngcono ukusebenza kokhonkolo. . I-retarder ingangezwa kukhonkolo, okuyinto esetshenziselwa amanzi aguqula amanzi anciphisa i-ejenti ukuze azivumelanise nesikhathi sokushisa ngaphansi kwezimo zokushisa ezahlukene. Ukungeza ingxenye ye-retarder kuzonciphisa inani le-slump ekhonkolo. Ngasikhathi sinye, lapho uhlanganisa i-retarder, kufanele kuqashelwe ukuthi i-restaarder ngokwayo inomphumela wokunciphisa amanzi, futhi lesi sici sidinga ukubhekwa ngesikhathi senqubo eyenziwe ngamanzi. Inkinga yokuvuza kwamanzi kukhonkolo nayo ijwayelekile kumaphrojekthi. Kulokhu, abakhulu kanye nama-ejenti okufaka umoya bangasetshenziswa ukwenza ngcono inkinga, kepha okuqukethwe komoya ngokhonkolo kudinga ukulawulwa kahle, uma kungenjalo amandla kakhonkolo azoncishiswa.
