Qhov ntsuas kub li cas cuam tshuam rau kev siv terrazzo prefabricated panels

Thaum lub sij hawm tsim kho ntawm terrazzo prefabricated panels, ib puag ncig ib puag ncig kub muaj qhov cuam tshuam loj, feem ntau cuam tshuam rau plaub yam: kev pheej hmoo tawg, kev tsim kho kom zoo, cov khoom siv, thiab kev saib xyuas. Cov kev cuam tshuam tshwj xeeb thiab kev tiv thaiv yog raws li hauv qab no:

1, Qhov cuam tshuam ntawm qhov kub thiab txias ib puag ncig (xws li kev tsim kho lub caij ntuj no)
Muaj kev pheej hmoo ntawm kev tawg
Tus nqi solidification ntawm cement- cov ntaub ntawv raws li qeeb ntawm qhov kub thiab txias. Yog tias tsis muaj kev ntsuas rwb thaiv tsev, cov dej evaporation qeeb yuav ua rau muaj kev ntxhov siab sab hauv thiab ua rau tawg tawg. Tshwj xeeb tshaj yog thaum ambient kub qis dua 5 degree, cov cement hydration cov tshuaj tiv thaiv yuav luag nres. Yog tias kev tsim kho raug yuam nyob rau lub sijhawm no, hauv av yog qhov ua rau hollowing thiab tawg vim Frost heave los yog tsis sib xws.
Txo kev tsim kho efficiency
Qhov kub thiab txias tuaj yeem ua kom ntev lub sij hawm solidification ntawm cov ntaub ntawv, piv txwv li, mortar bonding txheej yuav siv sij hawm ob peb hnub kom ncav cuag lub zog tsim, uas ua rau ncua sij hawm ntawm kev tsim kho. Nyob rau tib lub sijhawm, qhov nyuaj ntawm kev ua haujlwm ntawm cov neeg ua haujlwm nce, thiab cov txheej txheem xws li grouting thiab sib tsoo yuav tsum tau tswj qhov kub thiab txias, txwv tsis pub nws yuav cuam tshuam rau qhov smoothness.
Cov khoom siv degradation
Yog tias prefabricated panels los yog mortar khaws cia ntawm qhov kub thiab txias, kev puas tsuaj sab hauv tuaj yeem tshwm sim vim khov -thaw cycles, manifested li xim hloov thiab tsis muaj zog. Piv txwv li, thaum qhov ntsuas kub qis dua 0 degree, cov yas hauv pem teb yuav tsum tau muab tso rau hauv chav tsev kub 24 teev ua ntej kom rov zoo, txwv tsis pub nws yuav ua rau deformation.
Kev tiv thaiv:

Kaw qhov chaw tsim kho thiab siv cov cuab yeej siv cua sov kom tswj tau qhov kub thiab txias ntawm ntau dua lossis sib npaug li 5 degree.
Npog lub hauv paus pob zeb thiab mortar bonding txheej nrog cov ntaub ntawv rwb thaiv tsev (xws li paj rwb quilts thiab yas zaj duab xis) ua ntej nws qhuav, thiab tswj qhov kub zoo.
Xaiv cov cement resistant los yog ntxiv cov neeg sawv cev thaum ntxov, tab sis nruj me ntsis tswj cov tshuaj kom tsis txhob muaj qhov nce ntawm cov nqi shrinkage.
2, Qhov cuam tshuam ntawm qhov kub thiab txias ib puag ncig (xws li kev tsim kho lub caij ntuj sov)
Dej evaporates sai heev
Kub kub ua rau evaporation sai ntawm noo noo nyob rau saum npoo ntawm mortar. Yog tias tsis ntxiv lossis kho raws sijhawm, nws yooj yim los tsim cov xuab zeb qhov thiab qhov pores, txo qhov ntom ntom. Piv txwv li, tom qab sib tsoo, cov slurry yuav tsum tau ntxuav tam sim ntawd thiab coated nrog cov cement slurry ntawm tib xim, txwv tsis pub cov slurry yuav sai sai solidify ntawm kub kub thiab nws yuav nyuaj rau sau qhov tsis xws luag.
Thermal expansion thiab contraction teeb meem
Terrazzo has a high coefficient of expansion and may crack due to thermal expansion and contraction in environments with large temperature differences (such as day night temperature difference>15 degree). Tshwj xeeb tshaj yog tom qab qhov nrov ntawm cov cua sov hauv qab, cov cua sov tsis sib xws hauv av yuav ua rau qhov teeb meem no ntau dua.
Cov khoom ruaj khov txo qis
High temperature may accelerate the precipitation of alkaline substances in cement, leading to alkali bleeding and affecting its appearance. Meanwhile, if the storage temperature is too high (such as>32 degree), lub prefabricated board yuav deform vim thermal stress.
Kev tiv thaiv:

Thaum lub sij hawm tsim kho, lub ambient kub yuav tsum yog 20-25℃thiab cov av noo yuav tsum yog 50% -70%. Qhov kub ntawm qhov chaw tuaj yeem txo los ntawm cov tshuaj tsuag lossis shading.
Cov cheeb tsam loj hauv av yuav tsum tau nruab nrog cov kab sib koom ua ke, ua raws li cov pob qij txha ntawm cov pob zeb ua pob zeb, kom tso cov thermal stress.
Ntxiv polypropylene fibers los yog nteg mesh daim ntaub los txhim khu kev tiv thaiv tawg, los yog siv tsawg expansion coefficient cov ntaub ntawv xws li epoxy sib tsoo pob zeb li hloov.

3, Qhov cuam tshuam ntawm qhov kub thiab av noo hloov pauv
Cov av tsis sib xws ua rau muaj xim sib txawv
Yog tias muaj qhov sib txawv loj ntawm cov av noo hauv thaj chaw tsim kho (xws li nyob ze ntawm lub qhov rooj, qhov rais, lossis qhov qhib qhov cua), qhov dej ntawm cov cement yuav txawv, uas yuav ua rau muaj xim sib txawv. Piv txwv li, thaum rov qab mus rau Nantian, cov plag tsev terrazzo uas tsis tau muaj dej tsis zoo tuaj yeem nqus dej noo thiab rov ua kom cov dej noo, cuam tshuam rau cov tsos.
Tej yam kev mob tseem ceeb
Tom qab sib tsoo, nws yog ib qho tsim nyog yuav tsum tau siv cov cement slurry ntau zaus thiab kho rau 3-4 hnub. Yog hais tias qhov curing ib puag ncig kub hloov pauv tau zoo heev, nws yuav ua rau lub zog tsis sib xws. Piv txwv li, tom qab kev sib tsoo thib peb, nws yog ib qho tsim nyog yuav tsum tau yaug nrog dej huv thiab kho kom txog thaum lub npoo yog du thiab tsis muaj xuab zeb qhov. Yog tias qhov kub thiab txias qis dhau, nws yuav ua rau lub sijhawm kho kom ntev.
Kev tiv thaiv:

Xyuas kom muaj kev kho dej tsis zoo ntawm lub hauv paus ua ntej kev tsim kho kom tsis txhob muaj kev cuam tshuam ntawm qhov chaw ntub dej.
Siv lub tshuab dehumidifiers lossis cov khoom siv cua tshuab los tswj cov av noo thiab tswj xyuas qhov chaw ruaj khov.
Tsis tu ncua tuav hauv av, ua kom lub ntsej muag du, thiab txo qhov kev pheej hmoo ntawm cov dej noo infiltration.

4, Cov lus qhia rau kev teb rau cov xwm txheej tshwj xeeb
Pem teb cua sov ib puag ncig: Qhov tseem ceeb yuav tsum tau muab rau kev siv cov pob zeb epoxy sib tsoo los yog cov ntaub ntawv nthuav dav qis, thiab cov txheej txheem tsis zoo yuav tsum tau nruab nruab nrab ntawm cov av thiab cov kav dej hauv pem teb kom txo tau cov kev ntxhov siab.
Cov chaw ntub dej (xws li chav dej): Ua ntej kev tsim kho, nteg cov yob tsis muaj dej (xws li SBS rolls) thiab ntxiv kev kho cov nplaum nplaum rau saum npoo kom tsis txhob muaj kev pheej hmoo ntawm kev ntog.
Qhov chaw me me lossis nyuaj: Zam tsis txhob nrum-hauv- qhov chaw terrazzo, siv cov vaj huam sib luag ua ntej kom txo tau cov teeb meem sib koom ua ke, thiab npog cov cim sib koom ua ke los ntawm cov xim sib xws lossis qauv tsim.
