Nrog rau kev nce qib ntawm Lub Sijhawm, cov neeg rov qab los kuj muaj qhov zoo tshaj plaws.Sodium hexametaphosphateyog tus retarder feem ntau siv hauv polycarboxysalt. Nws yog ib hom ntawm admixture uas tuaj yeem ncua cov cement hydration cov tshuaj tiv thaiv, thiaj li ua kom lub sijhawm teem sijhawm ntawm cov pob zeb, kom cov pob zeb tshiab nyob rau lub sijhawm ntev los tswj cov yas, yooj yim nchuav, txhim kho kev tsim kho, thiab tib lub sijhawm, kev ua tau zoo ntawm cov pob zeb hauv lub sijhawm lig yuav tsis ua rau muaj kev phom sij.

Lub ntsiab sib txuas mechanism ntawmsodium hexametaphosphate, sodium hexametaphosphateTom qab nqus dej hauv viscose, nws muaj kev sib raug zoo nrog cov khoom ntawmsodium hexametaphosphatenws tus kheej, tus qauv rausodium hexametaphosphatebelongs rau ib hom ntawm phosphate,sodium hexametaphosphateanion muaj qhov hnyav molecular, feem ntau muaj PO3 gene naj npawb yog siab li 20-100, thiab tsim cov saw ntev.
Cov xwm txheej ua haujlwm:
1. Xaiv hom kev sib xyaw ua ke raws li kev ua tau zoo
2. Qhov ntau npaum ntawm admixture yuav tsum tau txiav txim los ntawm kev sib tw sib tw
3. Ua kev tshaj tawm kev ua haujlwm rau cov neeg ua haujlwm ua ntej pib ua haujlwm.
4. Teem ib tus neeg tshwj xeeb los saib xyuas cov haujlwm ntsuas
5. Npaj tus nqi ntawm cov khoom sib tov rau kev ua haujlwm no
