Qhov sib xyaw tsis raug: Qhov sib xyaw ua ke ntawm mortar, suav nrog qhov piv ntawm cov cement rau xuab zeb, dej, thiab lwm yam khoom ntxiv, yog qhov tseem ceeb. Yog tias qhov sib tov tsis raug, nws tuaj yeem ua rau cov mortar uas tsis muaj qhov tsim nyog cohesion thiab lub zog. Xyuas kom tseeb tias koj tau ua raws li cov chaw tsim khoom cov lus pom zoo lossis cov qauv kev lag luam rau cov khoom sib tov sib xyaw.
Cov ntsiab lus xuab zeb ntau dhau: Mortar nrog cov xuab zeb ntau dhau ntawm cov ntsiab lus ntawm cov cement tuaj yeem tsis muaj zog thiab ua rau tawg. Kev sib xyaw ua ke nrog qhov tseeb ntawm cov xuab zeb rau cov cement yog qhov tseem ceeb rau kev ua tiav lub zog xav tau.
Dej tsis txaus: Cov dej tsis txaus hauv qhov sib tov tuaj yeem ua rau qhuav thiab crumbly mortar. Kev tsim nyog hydration ntawm cov cement hais yog tsim nyog rau mortar kom ua tiav nws lub zog thiab cohesion. Xyuas kom tseeb tias koj siv cov dej sib xyaw kom raug.
Kev sib xyaw tsis raug: Kev sib xyaw kom zoo thiab sib xws yog qhov tseem ceeb rau cov khoom sib xws. Kev sib xyaw tsis txaus tuaj yeem ua rau cov khoom tsis sib xws thiab ua rau tawg. Sib tov mortar rau lub sijhawm pom zoo kom ua tiav homogeneity.
Kev kho tsis zoo: Curing mortar yog ib qho tseem ceeb kom tso cai rau nws kom muaj zog thiab kav ntev. Yog tias lub mortar tsis kho kom zoo los ntawm kev ua kom nws ntub rau lub sijhawm xav tau, nws tuaj yeem nyob tsis muaj zog thiab crumbly.
Kev siv cov khoom tsis zoo lossis cov khoom tsis zoo: Cov kab mob hauv cov xuab zeb lossis cov cement, xws li av nplaum lossis cov organic teeb meem, tuaj yeem cuam tshuam tsis zoo rau cov khoom khib nyiab. Ib txwm siv cov ntaub ntawv huv, zoo hauv koj cov mortar mix.
Txias-Thaw Damage: Yog tias mortar raug rau lub voj voog khov-thaw ua ntej nws kho kom txaus, nws tuaj yeem raug kev puas tsuaj uas ua rau nws tawg.
Kev sib khi tsis txaus: Kev sib txuas tsis zoo ntawm cov mortar thiab cov masonry tuaj yeem ua rau cov pob qij txha tsis muaj zog uas tawg thaum lub sijhawm. Xyuas kom meej tias qhov chaw huv si, npaj kom zoo, thiab cov tshuaj khib tau siv thiab compacted zoo.
Ua haujlwm dhau: Kev siv ntau dhau lossis rov ua haujlwm ntawm cov tshuaj khib nyiab tuaj yeem ua rau poob ntawm kev sib koom ua ke thiab lub zog. Tsis txhob overworking mortar thaum siv.
Teeb meem ntawm tus qauv: Qee qhov xwm txheej, cov khib nyiab khib nyiab tuaj yeem yog cov tsos mob ntawm cov teeb meem ntawm cov txheej txheem los yog txav mus rau hauv cov masonry, ua rau muaj kev ntxhov siab ntawm cov pob qij txha. Cov teeb meem zoo li no yuav xav tau kev ntsuam xyuas thiab kho dua.
Txhawm rau tiv thaiv cov khib nyiab khib nyiab, nws yog ib qho tseem ceeb los txheeb xyuas qhov laj thawj tshwj xeeb thiab siv cov kev ntsuas tsim nyog. Qhov no yuav suav nrog kev kho qhov sib xyaw ua ke, txhim kho cov txheej txheem sib xyaw, ua kom muaj kev kho kom zoo, thiab daws cov teeb meem ntawm cov txheej txheem yog tias tsim nyog. Kev sab laj nrog tus kws tshaj lij mason lossis tus neeg cog lus tuaj yeem pab txheeb xyuas qhov teeb meem thiab muab kev taw qhia txog kev ua haujlwm zoo tshaj plaws.
Peb Saner Heavy Industry (SEZG) tau tsim muaj nyob rau xyoo 2010, Peb tshwj xeeb hauv kev tsim ntau yam khoom siv twj tso kua mis, suav nrog kev teeb tsa lub tshuab, lub zog mining machinery, ib puag ncig engineering machinery, thiab kev tshawb fawb thiab kev tsim khoom tsim kev daws teeb meem rau underground engineering machinery.
