Ngokuqhubeka kweThe Times, i-retarder nayo inokweqa okufanelekile.I-sodium hexametaphosphatei-retarder evame ukusetshenziswa ku-polycarboxysalt.Kuwuhlobo lokuxutshwa okungabambezela ukusabela kwe-cement hydration, ukuze kwandiswe isikhathi sokumiswa kukakhonkolo, ukuze ukhonkolo omusha esikhathini eside ulondoloze ipulasitiki, ukuthululwa okulula, ukuthuthukisa ukusebenza kahle kokwakhiwa, futhi ngesikhathi esifanayo, ukusebenza kokhonkolo esikhathini sekwephuzile ngeke kubangele imiphumela emibi.

Indlela eyinhloko yokuhlanganisa yei-sodium hexametaphosphate, i-sodium hexametaphosphatengemva kokumunca amanzi ku-viscose, inobuhlobo obuseduze nezakhiwo zei-sodium hexametaphosphatengokwayo, ifomula yei-sodium hexametaphosphateiyingxenye yokwakhiwa kwe-phosphate,i-sodium hexametaphosphateI-anion inesisindo samangqamuzana aphezulu, ngokuvamile iqukethe inombolo yofuzo engu-PO3 iphezulu njengo-20-100, futhi yakha iketango elide.
Izimo zokusebenza:
1. Khetha izinhlobo ze-admixture ngokuvumelana nezidingo zokusebenza ezikhonkolo
2. Umthamo we-admixture kufanele unqunywe ngokulingana kwesivivinyo
3. Yenza ukudalulwa komsebenzi wobuchwepheshe kubasebenzi ngaphambi kokuqala umsebenzi.
4. Khetha umuntu okhethekile ozogada umsebenzi wokulinganisa
5. Lungiselela inani lenhlanganisela yalo msebenzi
