Dab tsi yog qhuav mortar additives?

Dry mortar additives yog cov khoom siv ntxiv rau cov tshuaj khib nyiab qhuav los txhim kho lawv cov kev ua tau zoo thiab cov khoom.Lawv tuaj yeem siv los txhim kho kev ua haujlwm, ua haujlwm ntev, kev sib txuas, thiab teeb tsa lub sijhawm ntawm cov mortar, nrog rau txo qis qis, tawg, thiab lwm yam kev puas tsuaj.Muaj ntau ntau hom tshuaj khib nyiab qhuav muaj, txhua tus muaj nws tus kheej muaj nuj nqi thiab yuav tsum tau ua.

1. Cellulose ethers Cellulose ethers yog ib qho ntawm feem ntau hom qhuav mortar additives.Lawv yog cov dej-soluble polymers muab tau los ntawm cellulose, uas yog ib tug natural polymer pom nyob rau hauv cov nroj tsuag.Cellulose ethers tuaj yeem siv los txhim kho kev ua haujlwm, kev sib txuas, thiab kev tuav dej ntawm cov tshuaj khib, nrog rau txo kev tawg thiab shrinkage.Lawv muaj txiaj ntsig tshwj xeeb hauv cov cement-based mortars thiab tuaj yeem siv rau ntau yam kev siv, nrog rau hauv pem teb, tiling, thiab plastering.
2. Redispersible polymer hmoov Redispersible polymer hmoov yog lwm hom qhuav mortar additive.Lawv yog cov hluavtaws polymers uas tau ntxiv rau cov tshuaj khib nyiab qhuav los txhim kho lawv cov kev sib raug zoo, kev ua haujlwm, thiab ua haujlwm ntev.Redispersible polymer hmoov feem ntau yog tsim los ntawm yas acetate-ethylene copolymer los yog acrylics thiab tuaj yeem siv rau ntau yam kev siv, nrog rau cov masonry, flooring, thiab tiling.
3. Retarders Retarders yog siv los ua kom qeeb lub sijhawm teeb tsa ntawm lub mortar, tso cai rau ntau lub sijhawm rau cov mortar ua haujlwm nrog thiab zoo li.Lawv yog tshwj xeeb tshaj yog pab tau nyob rau hauv kub thiab qhuav tej yam kev mob, qhov twg lub mortar yuav teem sai heev.Retarders feem ntau yog tsim los ntawm cov organic acids lossis cov suab thaj thiab yuav tsum tau siv rau hauv cov nqi kom raug kom tsis txhob cuam tshuam rau lub zog lossis kev ua haujlwm ntawm cov tshuaj khib nyiab.
4. Accelerators Accelerators yog siv los ua kom lub sijhawm teeb tsa ntawm lub mortar, cia nws kho sai dua.Lawv muaj txiaj ntsig tshwj xeeb hauv qhov txias thiab ntub dej, qhov twg cov tshuaj khib tuaj yeem siv sijhawm ntev dua.Accelerators feem ntau yog tsim los ntawm calcium chloride los yog lwm yam ntsev thiab yuav tsum tau siv nyob rau hauv qhov tseeb npaum li cas kom tsis txhob cuam tshuam rau lub zog los yog durability ntawm mortar.
5. Cua entrainers Cua entrainers yog siv los tsim cov pa me me npuas nyob rau hauv lub mortar, txhim kho nws workability thiab khov-thaw kuj.Lawv muaj txiaj ntsig tshwj xeeb hauv cov cheeb tsam uas tsis tshua muaj khov-thaw mus, qhov twg cov tshuaj khib tuaj yeem raug puas los ntawm dej khov thiab nthuav dav hauv nws qhov pores.Cov cua entrainers feem ntau yog tsim los ntawm surfactants los yog xab npum thiab yuav tsum tau siv nyob rau hauv qhov tseeb npaum li cas kom tsis txhob cuam tshuam rau lub zog los yog durability ntawm lub mortar.
6. Fillers Fillers yog siv los txo cov binder xav tau nyob rau hauv mortar, txhim kho nws cov hauj lwm thiab txo nws cov nqi.Lawv feem ntau yog tsim los ntawm silica lossis lwm yam minerals thiab tuaj yeem siv rau hauv ntau hom kev siv, xws li masonry, flooring, thiab tiling.

Zuag qhia tag nrho, qhuav mortar additives yog ib qho tseem ceeb ntawm cov khoom siv niaj hnub tsim, muab ntau yam txiaj ntsig thiab qhov zoo uas yog qhov tseem ceeb rau kev ua tiav kev ua tau zoo thiab cov txiaj ntsig.Los ntawm kev ua tib zoo xaiv thiab noj txhua qhov ntxiv hauv qhov sib tov, koj tuaj yeem tsim cov mortars uas muaj zog, ruaj, thiab haum rau koj daim ntawv thov.
