Dab tsi yog cov haujlwm thiab cov kev xav tau ntawm ntau yam ntaub ntawv hauv gypsum-based self-leveling mortar?

Gypsum-based self-leveling mortar yog ib hom khoom siv hauv pem teb uas feem ntau siv hauv kev tsim kho.Nws yog ib qho kev sib xyaw ntawm cov khoom sib txawv, suav nrog gypsum, aggregates, thiab additives, uas yog tsim los tsim kom muaj qhov sib luag thiab qib.Hauv tsab xov xwm no, peb yuav tham txog cov haujlwm thiab cov kev xav tau ntawm ntau yam ntaub ntawv hauv gypsum-based self-leveling mortar.

1. Gypsum Gypsum yog cov khoom tseem ceeb hauv gypsum-based self-leveling mortar.Nws yog cov ntxhia ntuj uas yog mined los ntawm lub ntiaj teb thiab tom qab ntawd ua tiav rau hauv cov hmoov zoo.Gypsum muab ntau lub luag haujlwm tseem ceeb hauv tus kheej-leveling mortar, suav nrog:

• Kev khi: Gypsum ua raws li kev khi, tuav lwm cov ntaub ntawv hauv kev sib xyaw ua ke.
• Kev teeb tsa: Gypsum teeb sai sai thaum sib xyaw nrog dej, uas tso cai rau lub mortar kom tawv thiab tsim kom muaj qhov chaw.
• Smoothness: Gypsum yog ib txwm du thiab tuaj yeem pab tsim kom muaj qhov ua tiav ntawm qhov chaw ntawm lub mortar.

Qhov zoo ntawm gypsum siv hauv kev sib xyaw yog qhov tseem ceeb, vim nws tuaj yeem cuam tshuam lub zog thiab teeb tsa lub sijhawm ntawm cov tshuaj khib.Lub gypsum yuav tsum tsis pub dawb los ntawm impurities thiab cov kab mob, thiab yuav tsum muaj qhov loj me me.

2. Aggregates Aggregates yog siv nyob rau hauv tus kheej-leveling mortar los muab ntau thiab kev ntxhib los mos.Lawv feem ntau yog tsim los ntawm cov xuab zeb lossis lwm yam khoom zoo.Cov aggregates siv nyob rau hauv kev sib tov yuav tsum huv si, tsis muaj kab mob, thiab ntawm ib tug loj npaum li cas.

Tus nqi thiab qhov loj ntawm cov aggregates siv nyob rau hauv qhov sib tov tuaj yeem cuam tshuam qhov ntws thiab qib ntawm cov tshuaj khib nyiab.Kev sib sau ntau dhau tuaj yeem ua rau cov mortar tuab heev thiab nyuaj rau kev ua haujlwm nrog, thaum sib sau me me tuaj yeem ua rau qhov tsis muaj zog thiab nkig.

3. Additives Additives yog siv nyob rau hauv tus kheej-leveling mortar los txhim kho nws cov kev ua tau zoo thiab cov khoom.Muaj ntau ntau hom additives uas yuav siv tau, txhua tus muaj nws tus kheej muaj nuj nqi thiab yuav tsum tau.

• Dej reducers: Cov dej reducers yog siv los txo cov dej uas xav tau hauv kev sib tov, uas tuaj yeem txhim kho lub zog thiab kev ua haujlwm ntawm cov mortar.Lawv yuav tsum tau siv raws li cov chaw tsim khoom cov lus qhia thiab yuav tsum muaj kev ua tau zoo los xyuas kom muaj kev ua tau zoo.
• Retarders: Retarders yog siv los ua kom qeeb lub sijhawm teeb tsa ntawm lub mortar, uas tuaj yeem muab sijhawm ntau rau cov mortar ua haujlwm nrog thiab zoo li.Lawv yuav tsum tau siv nyob rau hauv qhov tseeb npaum li cas thiab yuav tsum tsis txhob cuam tshuam lub zog los yog durability ntawm lub mortar.
• Plasticizers: Plasticizers yog siv los txhim kho cov dej ntws thiab kev ua haujlwm ntawm cov mortar, ua kom yooj yim rau cov ncuav thiab qib.Lawv yuav tsum tau siv nyob rau hauv qhov tseeb npaum li cas thiab yuav tsum tsis txhob cuam tshuam lub sij hawm teem los yog lub zog ntawm lub mortar.
• Fiber reinforcement: Fiber reinforcement tuaj yeem muab ntxiv rau hauv kev sib xyaw kom txhim kho lub zog thiab ruaj khov ntawm cov mortar, txo kev tawg thiab lwm yam kev puas tsuaj.Hom thiab tus nqi ntawm cov fiber ntau siv yuav tsum tsim nyog rau daim ntawv thov thiab yuav tsum tsis txhob cuam tshuam rau qhov ntws los yog qib ntawm cov tshuaj khib nyiab.

Zuag qhia tag nrho, kev ua haujlwm thiab kev xav tau ntawm ntau yam khoom siv hauv gypsum-based self-leveling mortar yog qhov tseem ceeb rau kev ua tiav kev ua haujlwm zoo thiab cov txiaj ntsig.Los ntawm kev ua tib zoo xaiv thiab muab txhua yam khoom siv hauv cov khoom sib xyaw, koj tuaj yeem tsim qhov du thiab qib nto uas muaj zog, ruaj, thiab haum rau koj daim ntawv thov.
