Lub Siab Ua Haujlwm Superplasticizer sawv cev los ntawm Polycarboxylate tus nqi qis dua, thiab qis qis dua kev ua tau zoo superplasticizer muaj qee qhov kev ua rau, uas ua rau cov dej, uas ua rau muaj kev ua kom muaj dej ntawm cov pob zeb ua tau zoo dua li cov tsoos superplastictizer. Vim yog cov txheej txheem sib txawv ntawm polycarboxylate superplasticizer, vim muaj cov txheej txheem sib txawv ntawm cov khoom siv sib txawv, cov kev hloov ntawm cov dej sib txawv hauv cov xuab zeb, qhov yuam kev ntawm lub Kev ntsuas lub zog thiab lwm yam laj thawj, ua rau muaj kev tsis ruaj khov ua haujlwm ntawm cov txheej txheem kev tsim kho (yooj yim dua) hauv kev tsim kho ntawm polycarboxylate superplasticer. Yuav tsis tuaj yeem ntsib cov kev tsim kho cov kev tsim kho. Yuav ua li cas xaiv polycarboxylate superplasticizer uas yooj yim tsim tau qhov chaw ruaj khov yog ib qho tseem ceeb yog qhov ua tau ruaj khov zoo ntawm kev ua vaj tse.
Nyob rau hauv kev xaiv ntawm polycarboxylate superplasticizylate tus nqi kev ntsuam xyuas, qhov rhiab heev ntawm polycarcozylate super ntawm polycarboxylate superplasticer.
(1) Nrhiav tau cov kev paub txog kev hloov pauv ntawm kev noj tshuaj
Kho cov chaw kuaj ua ke sib piv rau cov xwm txheej uas ua haujlwm ntawm lwm cov khoom tsis hloov pauv, nce lossis txo tus nqi ntawm admixture los ntawm 0.1% lossis 0.2% feem, thiab Tshawb pom cov khau khiab thiab nthuav dav ntawm cov qhob luag. Qhov me me ntawm qhov sib txawv ntawm cov ntsuas ntsuas thiab cov kev sib xyaw ua ke sib xyaw, cov tsis tshua nkag siab nws yog qhov hloov pauv ntawm tus nqi sib tov. Nws yog qhia tias cov dej txo tus neeg sawv cev muaj qhov zoo rhiab rau ntau npaum li cas. Lub hom phiaj ntawm kev kuaj pom no yog tiv thaiv lub xeev ntawm cov pob zeb sib tov los sib xyaw ntawm kev hloov ceev vim qhov yuam kev ntawm kev ntsuas ntsuas.
(2) Ntsuas cov rhiab rau kev hloov pauv hauv kev noj dej
Ib yam li ntawd, raws li cov sib tov sib piv ntawm pob zeb sib tov thaum nws ua tau raws li cov khoom siv roj hmab, thiab cov khoom siv roj raw yog nce lossis poob qis ntawm 5-8kg suav, uas yog, kev hloov pauv ntawm Cov dej xuab zeb tau simulated los ntawm 1%, thiab cov swb thiab kev nthuav dav ntawm pob zeb sib tov yog ntsuas feem ntau. Qhov me me qhov sib txawv ntawm cov pob zeb sib xyaw thiab cov theem pib sib piv, qhov zoo dua cov rhiab ntawm cov dej haus dej. Yog tias qhov kev hloov hauv kev noj dej tsis yog rhiab, nws tuaj yeem yooj yim los tswj kev tsim khoom.
(3) Kuaj cov kev yoog tau ntawm cov ntaub ntawv raw
Khaws cov theem pib sib xyaw sib txawv tsis hloov pauv, hloov cov pob zeb raw cov ntaub ntawv, muaj kev ntsuas ntawm cov kev hloov pauv, thiab ntsuas cov thoob ntiaj teb ntawm kev yoog raws li cov khoom siv nyoos.
(4) yoog raws li qhov kub hloov
Khaws cov theem pib sib tov sib txawv tsis hloov pauv, feem kev hloov pauv ntawm pob zeb tawg thiab kev hloov pauv ntawm kev hloov pauv ntawm cov khoom siv raw.
(5) Hloov cov xuab zeb
Nce lossis txo qis cov xuab zeb tsawg los ntawm 1%, saib lub xeev ntawm cov pob zeb sib xyaw, ntsuas cov nyiaj txiag, thiab cov pob zeb ua tau hloov pauv.
