Plastering qhuav hmoov mortar hom thiab cov qauv yooj yim
1. Kev faib khoom
① Raws li kev ua haujlwm ntawm plastering mortar, nws tuaj yeem muab faib ua:
Feem ntau, plastering mortar tuaj yeem muab faib ua cov plastering mortar zoo tib yam, zoo nkauj plastering mortar, waterproof plastering mortar thiab plastering mortar nrog qee qhov tshwj xeeb ua haujlwm (xws li rwb thaiv tsev kub, acid tiv thaiv, thiab hluav taws xob pov thawj mortar).
② Kev faib tawm raws li cov khoom siv cementitious siv hauv plastering mortar
A.Plastering mortars nrog inorganic binders (cement, gypsum los yog slaked txiv qaub).
B.Kho kom zoo nkauj stucco mortars siv cov cement, redispersible hmoov los yog slaked txiv qaub li khi.
C.cement-based plasters yog siv rau sab nrauv daim ntaub ntawv thiab chav ntub dej, thaum gypsum-based plasters yog siv tshwj xeeb rau cov phab ntsa sab hauv.
2. Reference formula
Rau cov plastering mortar rau sab hauv thiab sab nrauv phab ntsa ntawm cov phab ntsa uas tsis yog tshwj xeeb ua haujlwm cib, nws yog feem ntau xaiv lub zog compressive ntawm 10MPa lossis 15MPa, tab sis cov khoom siv qis thiab lub zog siab kuj tuaj yeem ua raws li cov khoom tshwj xeeb. kev xav tau.
Cov lus pom zoo yog ntxiv 1% ~ 4% RE5010N rau cov cement lossis txiv qaub-cement raws li plaster tiav, uas tuaj yeem txhim kho nws cov adhesion, hnav tsis kam thiab yoog raws.Tsis tas li ntawd, nws tseem pom zoo kom ntxiv 0.2% ~ 0.4% ntawm cellulose ether, starch ether los yog sib tov ntawm ob qho tib si.Nws yog tshwj xeeb tshaj yog pom zoo kom siv redispersible polymer hmoov RI551Z thiab RI554Z nrog hydrophobicity los txhim kho cov kev ua tau zoo ntawm plastering thiab plastering.
Mortar Additive Masterbatch Taw Qhia
Lub mortar additive masterbatch muaj cov khoom nram qab no: sodium fatty cawv polyethylene sulfonate, cellulose, sodium sulfate, starch ether, thiab lwm yam.
Lub luag haujlwm tseem ceeb: huab cua-entraining, thickening, yas-retaining, kev ua tau zoo-txhim kho thiab lwm yam tshwj xeeb los, tsuas yog cov khoom nyob rau hauv lub teb chaws uas tsis sib tov raws li cov cement loj piv.Txuag cov cement nyob rau hauv cov mortar sib tov tsis tsuas yog ua kom lub zog tab sis kuj txhim kho lub durability, impermeability thiab tawg kuj.
Cov yam ntxwv thiab kev ua tau zoo thiab kev ua tau zoo thiab kev ua tau zoo thiab kev ua tau zoo:
1. Txhim kho mortar workability thiab ua hauj lwm efficiency
Thaum lub sij hawm masonry thiab plastering, lub mortar yog loj, mos, thiab muaj zog cohesive quab yuam.Cov nplaum nplaum nplaum tsis nplaum rau lub duav, txo cov av tshauv thiab cov nqi, thiab cov mortar muaj qhov siab ntawm qhov puv.Nws muaj qhov yuav tsum tau tsawg ntawm cov dej ntub dej ntawm phab ntsa, thiab qhov shrinkage ntawm mortar yog me me, uas kov yeej cov teeb meem xws li tawg, hollows, shedding, thiab foaming ntawm phab ntsa, thiab daws cov teeb meem ntawm mortar workability.Lub mortar yog khaws cia rau 6-8 teev yam tsis muaj sedimentation, khaws dej zoo, tsis muaj kev sib cais ntawm cov tshuaj khib hauv cov hmoov tshauv, thiab tsis tas yuav rov ua dua, uas ua rau kev tsim kho sai thiab txhim kho kev ua haujlwm.
2. Cov nyhuv thaum ntxov
Lub mortar tov nrog mortar additives muaj affinity thiab ntxiv dag zog rau cov cement.Los ntawm cov txheej txheem plasticizing, nws ncav cuag ib lub zog tom qab 5-6 teev ntawm kev siv, thiab tom qab ntawd lub zog zoo dua.
3. Kev txuag dej
Lub mortar npaj nrog mortar additives muaj kev sib cais ntawm cov dej, uas tuaj yeem txo cov dej haus, txo qhov shrinkage ntawm plastered phab ntsa thiab txhim kho lub zog.
4. Cov haujlwm ntxiv
Lub mortar npaj nrog mortar additives muaj lub luag haujlwm ntawm kev tuav dej, txo suab nrov, txuag hluav taws xob, rwb thaiv tsev kub, thiab Frost tsis kam.
