Thaum xub thawj cov pob zeb sib xyaw tsuas yog siv los txuag cov cement, nrog rau kev tsim kho tshuab
Vim yog siv cov superplasticizers, high-fluidity pob zeb, nws tus kheej-compacting pob zeb, thiab high-strength pob zeb yog siv; vim qhov sib ntxiv ntawm cov thickeners, kev ua haujlwm ntawm cov pob zeb hauv qab dej tuaj yeem txhim kho; vim qhov sib ntxiv ntawm cov retarders, lub sij hawm nruab nrab ntawm cov cement tuaj yeem ua kom ntev Yog li, nws tuaj yeem txo qhov poob qis thiab ua kom lub sijhawm ua haujlwm ntev; vim yog siv cov tshuaj tiv thaiv kab mob, qhov chaw khov ntawm cov tshuaj tuaj yeem txo qis, lossis qhov deformation ntawm cov dej khov siv lead ua yuav tsis ua rau kev puas tsuaj. Kev tsim kho ntawm qhov kub tsis zoo yog ua tau.
Kev ceev faj rau kev siv Polycarboxylate hom superplasticizer
Polycarboxylic acid superplasticizer muaj dej txo, txhim kho thiab kev tiv thaiv slump, yog ib qho tseem ceeb ntxiv los txhim kho kev ua tau zoo ntawm pob zeb, tab sis, hauv kev siv, kuj tseem muaj qee yam yuav tsum tau them sai sai rau.
Kev ceev faj rau kev siv polycarboxylic dej reducer:
1, muaj teeb meem nrog kev hloov pauv ntawm cov cement. Rau ib tus neeg cov cement yuav tshwm sim cov dej txo qis, kev poob qis yog qhov tshwm sim loj dua, yog li ntawd, nyob rau hauv qhov kev hloov pauv tsis zoo nrog cov cement, qhov xav tau ntawm polycarboxylic acid water reducer test adjuster, txhawm rau xyuas kom muaj txiaj ntsig zoo.
2. Kev hloov pauv ntawm cov khoom siv raw. Thaum qhov zoo ntawm cov xuab zeb, pob zeb cov ntaub ntawv thiab cov khoom siv xws li ya tshauv, hmoov av thiab lwm yam khoom siv raw hloov pauv, nws yuav muaj qee yam cuam tshuam rau kev ua haujlwm ntawm pob zeb, thiab nws yuav tsum tau kho kom haum rau lub sijhawm no.
3. Vim tias cov dej txo qis ntawm Polycarboxylate type superplasticizer, cov dej haus yog rhiab heev rau cov slump ntawm coagulation txheej. Yog li ntawd, nyob rau hauv tus txheej txheem ntawm kev siv yuav tsum nruj me ntsis tswj tus nqi ntawm polycarboxylic acid dej txo tus neeg sawv cev thiab cov pob zeb siv dej. Ib zaug dhau lawm, pob zeb yuav tshwm sim cais, los ntshav, tawv thiab roj cov ntsiab lus yog loj heev thiab lwm yam tshwm sim tsis zoo.
4. Nws yog tshwj xeeb yog rhiab heev rau cov av nkos cov ntsiab lus, thiab cov av nkos ntau dhau yuav txo qhov kev ua tau zoo ntawm polycarboxylic acid dej reducer. Yog li ntawd, qhov zoo ntawm kev sib sau yuav tsum nruj me ntsis tswj thaum siv polycarboxylic acid dej reducer. Qhov ntau npaum ntawm polycarboxylic acid dej reducer yuav tsum tau nce ntxiv thaum cov av nkos cov ntsiab lus nce ntxiv.
5. Lub polycarboxylate superplasticizer tsis tuaj yeem tov nrog naphthalene superplasticizer. Kev siv cov polycarboxylate superplasticizer yuav tsum tau ntxuav nrog naphthalene superplasticizer tov khoom thiab tov khoom, txwv tsis pub nws yuav ua rau cov polycarboxylate superplasticizer poob dej. cuam tshuam.
6. Kev sib cuag ntev nrog cov ntaub ntawv ferrous yuav tsum zam. Vim tias cov khoom siv polycarboxylate superplasticizer feem ntau yog acidic, thiab kev sib cuag ntev nrog cov khoom siv hlau yuav hnov mob maj mam, thiab txawm ua rau cov xim tsaus thiab tsaus dua, ua rau txo cov khoom ua haujlwm. Nws raug nquahu kom siv polyethylene yas lossis stainless hlau nruas rau kev khaws cia kom ruaj ntseg ntawm nws qhov kev ua tau zoo.
