Ua ntej, lub tswv yim thiab qhov zoo thiab qhov tsis zoo ntawm mortar self-mixing
Mortar self-mixing yog hais txog qhov chaw tsim kho raws li ib feem ntawm nws tus kheej-kev npaj ntawm mortar, piv nrog npaj txhij-siv mortar, nws tus kheej sib xyaw mortar tuaj yeem hloov kho raws li qhov xwm txheej tshwj xeeb, tsim nyog rau kev tsim kho me me thiab qhov chaw nyob deb. los ntawm lub nroog. Txawm li cas los xij, tib lub sijhawm, kuj tseem muaj qhov tsis zoo xws li kev nyuaj siab hauv kev tswj xyuas kom zoo, lub sijhawm siv sijhawm ntev, thiab nyuaj rau lav lub zog.
Thib ob, cov kev cai tshwj xeeb ntawm mortar nws tus kheej sib tov
1. Qhov kev faib ua feem ntawm cov ntaub ntawv yuav tsum yog: mortar feem ntau yog tsim los ntawm peb cov ntaub ntawv: cement, xuab zeb thiab dej, thiab tus nqi tsim nyog yog cement: xuab zeb=1:3-4, thiab cov dej yuav tsum tswj kom tsim nyog, feem ntau tsis pub tshaj 50% ntawm cov cement. Thaum yuav cov khoom siv raw, nws yog ib qho tsim nyog yuav tsum xaiv cov cement, nplua xuab zeb thiab dej ntshiab.
2. Lub sij hawm stirring yuav tsum txaus: Lub sij hawm sib tov ntawm mortar yog ib qho tseem ceeb cuam tshuam rau nws lub zog, thiab lub sij hawm stirring feem ntau yuav tsum tsis pub tsawg tshaj 3 feeb los xyuas kom meej tias nws yog tag nrho tov. Lub stirring ceev thiab siv yuav tsum tau tswj thaum stirring kom tsis txhob muaj porosity thiab adhesion.
3. Kev tsim kho ib puag ncig yuav tsum ua tau raws li tus qauv: Thaum lub sij hawm siv tshuaj khib, qhov chaw tsim kho ib puag ncig yuav tsum tau ua kom qhuav thiab huv si, kom tsis txhob muaj plua plav thiab cov khoom sib xyaw ua ke rau hauv cov mortar, uas yuav cuam tshuam rau kev tsim kho kom zoo. thiab cuam tshuam. Nyob rau tib lub sijhawm, qhov ntsuas kub uas tsim nyog yuav tsum tau khaws cia thaum lub sijhawm tsim kho kom tsis txhob muaj teeb meem tshwm sim los ntawm kev sib xyaw ua ke qeeb dhau ntawm qhov kub thiab txias dhau los ntawm cov evaporation ceev heev ntawm cov dej kub.
4. Lub zog ntawm cov mortar yuav tsum tau ua kom ntseeg tau: lub zog ntawm tus kheej sib xyaw mortar muaj feem xyuam nrog cov khoom sib faib, cov dej sib tov, qib ntawm kev sib xyaw ntawm kev sib xyaw thiab lwm yam, txhawm rau kom ntseeg tau tias nws lub zog. ncav cuag tus txheej txheem, nws yuav tsum tau hloov kho kom tsim nyog thiab tsim ua raws li kev tsim kho tshwj xeeb. Lub zog compressive ntawm mortar feem ntau yuav tsum muaj ntau tshaj 10MPa.
