7. Xa i-polycarboxylic acid admixture ilingo-ixutywe (kwimveliso), xa kuphela i-dosage esisiseko ifikelelwe, ukusebenza kokuqala kwekhonkrithi kuya kwaneliswa, kodwa ilahleko yekhonkrithi iya kuba nkulu; ngoko ke, ngexesha lokuxuba uvavanyo (ukuveliswa), imali kufuneka inyuswe ngokufanelekileyo. Kuphela ngokulungelelanisa idosi (oko kukuthi, ukufikelela kwidosi ye-saturation) ingxaki yokulahleka okukhulu kwe-slump ingasonjululwa.

8.Emva kokunciphisa inani lezinto ze-cementitious, umlinganiselo wamanzi-samente kufuneka uqinisekiswe ngakumbi ngexesha lenkqubo yokuvelisa. Ukuba ilahleko ye-slump inkulu, indlela yodwa kukunyusa inani le-admixture kwaye ungeze i-admixture kabini. Musa ukongeza amanzi ukusombulula ingxaki, ngaphandle koko kuya kubangela ukuhla okukhulu kwamandla.

9. I-agent ye-Polycarboxylate yokunciphisa amanzi yimveliso enezinga eliphezulu lokunciphisa amanzi kunye nokusabalalisa okuphezulu. Kulawulo lwemveliso, isalathisi se-fluidity (ukwandiswa) kwekhonkrithi kufuneka isetyenziswe ukulinganisa ukusebenza kwekhonkrithi. I-slump ingasetyenziswa kuphela njengexabiso lereferensi.

10. Amandla ekhonkrithi ngokuyinhloko anqunywe ngumlinganiselo wokubopha amanzi. I-agent yokunciphisa amanzi e-Polycarboxylate ineempawu zokunciphisa izinga eliphezulu lokunciphisa amanzi, elinokunciphisa ngokulula ukusetyenziswa kwamanzi kwi-mix mix ratio, ngaloo ndlela ifezekise injongo yokunciphisa umlinganiselo wokubopha amanzi kunye nokunciphisa amandla ekhonkrithi. iindleko ezibanzi. Kuba imathiriyeli ekrwada iguquguquka ngakumbi ngexesha lemveliso kunangexesha lovavanyo, ukuze kusetyenziswe ngcono ukusebenza kweemveliso zepolycarboxylate superplasticizer, imixube kufuneka ihlengahlengiswe ngexesha elifanelekileyo ngokwempembelelo yeemeko zemathiriyeli ekrwada, utshintsho lobushushu obuphakathi, njl. ikhonkrithi ngexesha lemveliso. Umthamo.

11. I-Polycarboxylic acid i-agent yokunciphisa amanzi ayinakuxutywa kunye ne-naphthalene-based based-reduction agents. Xa usebenzisa i-polycarboxylic acid i-agent yokunciphisa amanzi, i-mixer kunye ne-mixer iloli eye yasebenzisa i-naphthalene-based based-reduction agents kufuneka ihlanjwe icocekile, ngaphandle koko i-agent ye-polycarboxylic acid yokunciphisa amanzi inokonakala. I-arhente yokunciphisa amanzi ilahlekelwa yimpembelelo yayo yokunciphisa amanzi.

12. I-Polycarboxylate superplasticizer kufuneka igweme ukudibanisa ixesha elide kunye nezixhobo zentsimbi. Kuba iimveliso ze-polycarboxylate zokunciphisa amanzi zihlala zine-asidi, ukudibana kwexesha elide kunye neemveliso zentsimbi kuya kubangela ukusabela okucothayo, okunokuthi kube mnyama okanye kube mnyama umbala, okukhokelela ekwehleni kokusebenza kwemveliso. Kunconywa ukusebenzisa iibhakethi zeplastiki ze-polyethylene okanye iibhakethi zensimbi ezingenasici zokugcina ukuqinisekisa ukuzinza kokusebenza.
