Hnub Kawg: 10 Lub Kaum Hli, 2023
Cov kev ua tau zoo superplasticizer sawv cev los ntawm polycarboxylate superplasticizer muaj qhov zoo ntawm cov ntsiab lus tsawg, cov dej txo qis, zoo slump tuav kev ua tau zoo thiab qis shrinkage, thiab polycarboxylate superplasticizer superplasticizer muaj qee qhov ua rau, uas ua rau lub fluidity, Frost tsis kam thiab dej tuav. ntawm pob zeb zoo dua li cov tsoos superplasticizer. Vim muaj ntau hom kev sib xyaw ua ke ntawm polycarboxylate superplasticizer, cov khoom lag luam zoo ntawm cov tuam txhab sib txawv sib txawv heev, ua ke nrog cov txheej txheem tsim khoom, vim qhov hloov pauv ntawm qhov zoo ntawm cov khoom siv raw, kev hloov ntawm cov dej hauv cov xuab zeb, qhov yuam kev ntawm cov kev ntsuas qhov system thiab lwm yam laj thawj, ua rau kev ua haujlwm tsis ruaj khov ntawm kev sib xyaw ua ke (yooj yim rau kev sib cais lossis kev poob qis sai heev) hauv kev tsim kho ntawm polycarboxylate superplasticizer. Tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. Yuav ua li cas xaiv polycarboxylate superplasticizer uas yooj yim los tswj thiab yooj yim los tsim cov khoom ruaj khov yog ib qho tseem ceeb kom ua tiav qhov zoo ntawm cov pob zeb.
Nyob rau hauv kev xaiv ntawm polycarboxylate superplasticizer ntxiv rau cov kev ntsuam xyuas kev ua tau zoo, xws li cov ntsiab lus ntawm cov khoom, cov dej txo tus nqi, slump retention thiab lwm yam kev ntsuam xyuas kev ua tau zoo, qhov rhiab heev ntawm polycarboxylate superplasticizer yuav tsum tau sim kom nkag siab txog qhov zoo ntawm polycarboxylate superplasticizer.
(1) Kev tshawb pom rhiab heev rau kev hloov pauv ntau npaum
Kho qhov kev ntsuas qhov sib xyaw ua ke rau qhov xwm txheej uas qhov ua haujlwm tau zoo thiab poob qis ntawm cov pob zeb sib xyaw ua tau raws li qhov yuav tsum tau ua, khaws cov khoom siv ntawm lwm cov khoom siv raw ntawm cov pob zeb tsis hloov, nce lossis txo cov khoom sib xyaw los ntawm 0.1% lossis 0.2% feem, thiab xyuas qhov slump thiab expansion ntawm qhob feem. Qhov me dua qhov sib txawv ntawm qhov ntsuas tus nqi thiab qhov sib xyaw ua ke, qhov tsis tshua muaj siab yog qhov hloov pauv ntawm qhov sib xyaw. Nws tau pom tias cov dej txo tus neeg sawv cev muaj qhov zoo rhiab heev rau cov tshuaj. Lub hom phiaj ntawm qhov kev tshawb nrhiav no yog txhawm rau tiv thaiv lub xeev ntawm cov pob zeb sib tov los ntawm kev hloov pauv sai vim qhov yuam kev ntawm qhov ntsuas qhov system.
(2) Txheeb xyuas qhov rhiab heev rau kev hloov pauv hauv kev siv dej
Ib yam li ntawd, raws li qhov sib xyaw ua ke ntawm cov pob zeb sib xyaw thaum nws ua tau raws li qhov yuav tsum tau ua, tus nqi ntawm lwm cov ntaub ntawv raw tseem tsis hloov pauv, thiab cov dej siv ntawm cov pob zeb tau nce los yog txo los ntawm 5-8kg / cubic meter feem, uas yog, qhov hloov pauv ntawm xuab zeb cov ntsiab lus yog simulated los ntawm 1%, thiab cov slump thiab expansion ntawm qhob mix yog ntsuas raws li. Qhov sib txawv me me ntawm qhov sib xyaw ua ke thiab qhov sib xyaw ua ke yooj yim, qhov zoo dua qhov rhiab heev ntawm kev siv dej ntawm cov dej reducer. Yog tias qhov kev hloov pauv ntawm kev siv dej tsis zoo, nws tuaj yeem yooj yim los tswj kev tsim khoom.
(3) Ntsuas qhov hloov pauv ntawm cov khoom siv raw
Khaws qhov sib xyaw ua ke ntawm qhov sib piv tsis hloov pauv, hloov cov khoom siv raw, raws li kev ntsuas qhov poob qis thiab kev nthuav dav ntawm cov pob zeb sib xyaw tom qab kev hloov pauv, thiab ntsuas qhov universality ntawm kev hloov mus rau cov khoom siv raw.
(4) Adaptability rau kub hloov
Ua kom qhov sib xyaw ua ke tsis hloov pauv, raws li ntsuas qhov kev hloov pauv ntawm kev poob qis thiab nthuav dav ntawm kev sib xyaw ua ke tom qab kev hloov pauv, ntsuas lub universality ntawm adaptation rau raw cov ntaub ntawv.
(5) Hloov cov xuab zeb
Nce lossis txo cov xuab zeb los ntawm 1%, saib xyuas lub xeev ntawm cov pob zeb sib xyaw, ntsuas qhov hloov pauv ntawm cov xuab zeb thiab pob zeb, thiab seb lub xeev pob zeb tau hloov pauv loj npaum li cas.
