Ndi kupita patsogolo kwa The Times, retarder ilinso ndi chiwopsezo chapamwamba.Sodium hexametaphosphatendi retarder yomwe imagwiritsidwa ntchito kwambiri mu polycarboxysalt. Ndi mtundu wa admixture kuti akhoza kuchedwetsa simenti hydration anachita, kuti kutalikitsa kuika nthawi konkire, kuti konkire mwatsopano mu nthawi yaitali kukhala plasticity, yabwino kuthira, kusintha ntchito yomanga, ndipo nthawi yomweyo, kugwira ntchito kwa konkire kumapeto kwa nthawi sikudzabweretsa zotsatirapo zoipa.

Waukulu kugwirizana limagwirira wasodium hexametaphosphate, sodium hexametaphosphatemutatha kuyamwa madzi mu viscose, ili ndi ubale wapamtima ndi katundu wasodium hexametaphosphatepalokha, formula yasodium hexametaphosphateali amtundu wa phosphate,sodium hexametaphosphateanion ali ndi kulemera kwakukulu kwa maselo, nthawi zambiri amakhala ndi nambala ya jini ya PO3 yomwe imakhala yokwera kufika pa 20-100, ndipo imapanga unyolo wautali.
Momwe mungagwiritsire ntchito:
1. Sankhani mitundu yosakanikirana molingana ndi zofunikira za konkriti
2. Mlingo wa admixture uyenera kutsimikiziridwa ndi mayesero
3. Pangani ukadaulo waukadaulo kwa ogwira ntchito musanayambe ntchito.
4. Sankhani munthu wapadera kuti aziyang'anira ntchito yoyezera
5. Konzani kuchuluka kwa kusakaniza kwa ntchitoyi
