Nano silica Lub cev muaj zog:
Cov tsos ntawm nano silica yog amorphous dawb hmoov. Qhov loj ntawm cov khoom yog 1-100 nanometers, microstructures yog kheej kheej, thiab cov khoom yog floc thiab reticulate quasi granular qauv.
Dissolving zog: tsis tuaj yeem yaj hauv dej thiab kua qaub (tshwj tsis yog hydrofluoric acid) thiab cov kuab tshuaj organic, thiab tuaj yeem yaj hauv alkali thiab hydrofluoric acid.
Stability: kev ruaj ntseg
Daim ntawv thov tseem ceeb:
Kev siv nano silica yog siv dav heev, qhov hnyav yog 0.5 - 2%, thiab cov khoom lag luam tus kheej tuaj yeem ncav cuag ntau dua 10%. Tus yuam sij rau kev ua tau zoo ntawm cov khoom yog tias nws yog tag nrho dispersed rau hauv lub system. Raws li cov txheej txheem sib txawv, silica nanoparticles yog dispersed nyob rau hauv dej, acetone, alcohols los yog lwm yam kuab tshuaj raws li txawv systems. Rau cov roj-raws li tshuab, auxiliaries tuaj yeem ntxiv rau pretreatment.
Pob zeb yog cov khoom siv feem ntau siv rau kev tsim kho thiab lawv cov qauv siv yuav luag tag nrho cov cement ntau lawm hauv ntiaj teb. Kev siv cov cement ntau ua rau cov pa roj carbon monoxide nce ntxiv, thiab ua rau lub tsev ntsuab tshwm sim. Ib txoj hauv kev los txo cov ntsiab lus ntawm cov cement hauv cov pob zeb sib xyaw yog siv cov silica nplua. Ib qho ntawm cov silica nplua uas muaj peev xwm ua tau raws li kev hloov cov cement thiab cov pob zeb ntxiv yog nano-silica. Txawm li cas los xij, kev lag luam Nano silica yog synthesized nyob rau hauv ib txoj kev nyuaj, ua rau siab purity thiab complex txheej txheem uas ua rau lawv tsis muaj peev xwm rau kev tsim kho kev lag luam. Tsis tas li ntawd, daim ntawv thov ntawm Nano silica thiab nws cov nyhuv hauv pob zeb tseem tsis tau nkag siab tag nrho.
Nano silica hauv pob zeb:
Nano silica (sib npaug rau SY-SP30) tuaj yeem txhim kho qhov kev hloov pauv ntawm cov qauv sib xyaw thiab muab tshuaj txhuam hauv pob zeb, thiab ua pov thawj ntawm nano silica (sib npaug SY-SP30) ntawm cov khoom ntawm pob zeb los ntawm microcosmic lub kaum ntse ntse. Huab cua entraining tus neeg sawv cev tuaj yeem txhim kho cov pob zeb tawg tab sis nws tuaj yeem txo qis qhov nthuav dav me ntsis; tuaj yeem txo lub zog compressive ntawm pob zeb ntawm txhua theem; tuaj yeem txo tus kheej shrinkage hom ntawm pob zeb; txhim kho cov pob zeb tiv thaiv permeability thiab Frost tsis kam ntawm Cl-, tshwj xeeb tshaj yog Frost tsis kam thiab kav ntev. Txawm hais tias tus retarder tuaj yeem txo qis lub zog thaum ntxov ntawm cov pob zeb, nws muaj kev cuam tshuam me ntsis rau tom qab lub zog ntawm pob zeb.
