5 Tus dej sawv cev tus neeg sawv cev
superplasticizer, tseem hu ua dispersant lossis ntws tus neeg sawv cev ntawm cov cement, tuaj yeem ua rau plasticize lossis deflocculate castables, yog li nws tseem hu ua plasticizer lossis deflocculant, uas tuaj yeem txo cov dej haus ntawm kev sib xyaw, lossis nce fluidity lossis plasticization nyob rau hauv qhov xwm txheej ntawm kev haus dej tsis tu ncua. Kev siv dej ntawm cov dej nqus dej yog 0.2 ~ 1% ntawm cov phaus cement. Sodium tripolyphosphate (na2p3on0) tuaj yeem siv los ua cov ntsuas dej.
6 tus neeg sawv cev ua npuas ncauj
Tus neeg sawv cev ua npuas ncauj, tseem hu ua tus neeg sawv cev ua npuas, tuaj yeem tsim ua npuas dej ruaj khov dua. Nws yog cov khoom siv uas tuaj yeem ua rau cov khoom siv muaj qhov kaw (lossis txuas nrog) pore qauv. Cov xwm txheej ntawm foaming thiab ruaj khov yog txo qhov nro ntawm cov kua-roj interface thiab tsim cov zaj duab xis nyob ib puag ncig cov npuas, kom cov pa hauv npuas tsis yooj yim rau kev khiav dim thiab cov npuas tsis yooj yim rau txuas. Rosin xab npum feem ntau yog siv los ua tus neeg sawv cev ua npuas ncauj thaum tsim cov khoom hluav taws xob los ntawm kev ua npuas dej.
7 Tus neeg sawv cev nthuav dav
Cov neeg sawv cev nthuav dav rau cov khoom siv tsis tuaj yeem suav nrog kyanite, quartz, thiab lwm yam, ntawm qhov twg kyanite zoo dua thiab muaj qib siab ntawm kev nthuav dav. Nws tsis txawv txav hloov mus rau mullite thiab SO2 ntawm qhov kub, nrog cov yam ntxwv nthuav dav. Quartz (SO2) nws txawv nrog qhov kub thiab txias, nrog kev loj los ntim.
8 tawg
dispersant yog ib hom khoom sib txawv uas tuaj yeem ua rau cov pab pawg flocculent lossis kua dej ntawm cov khoom tawg ua kom sib cais mus rau hauv cov khoom tawg tau raug tshem tawm hauv cov kua, feem ntau yog surfactants. Nws tuaj yeem txo qhov adsorption ntawm cov khoom me me (lossis dej ntws) thiab tiv thaiv flocculation lossis agglomeration, yog li nws kuj tseem siv tau ua emulsifier lossis stabilizer. Superplasticizer, calcium lignosulfonate thiab zib suab thaj yuav siv tau los ua cov khoom siv tiv thaiv kom tsis txhob muaj cov pob zeb hauv av ua ke nrog cov nplais, kom thiaj li txhim kho cov npliag ntawm cov nplais roj nplua mias, txo kev los ntshav, thiab txhawb kom sai thiab zoo li qub hydration ntawm cov cement ntau, uas yog cov muaj txiaj ntsig. txhawm rau txhim kho cov khoom ua haujlwm ua haujlwm thiab cov qauv ntawm cov khoom.
muaj ntau hom admixtures uas tuaj yeem muab ntxiv rau qhov chaw pov, thiab tag nrho cov tau muaj txiaj ntsig zoo ntawm kev siv cov khoom. Cov quab yuam tuaj yeem pom kom meej meej, xws li txo cov dej noo hauv qhov khoom, tiv thaiv qhov ntim tsawg ntawm cov khoom, txhim kho nws cov kev ua haujlwm hauv kev tsim kho, thiab lwm yam. rau qhov xwm txheej ntawm cov khoom nws tus kheej, kev siv kub, thaj chaw tsim kho, thiab lwm yam kom txuas ntxiv xaiv cov khoom tsim nyog.
