Dab tsi yog cov txheej txheem tseem ceeb rau kev ntub dej -Cov pov thawj Kev Kho Mob Ntawm Cov Khaub Ncaws Terrazzo hauv chav dej?

Cov txheej txheem tseem ceeb ntawm kev tiv thaiv- zoo li qub terrazzo hauv chav dej noo- pov thawj kev kho mob yuav tsum tau rov qab los ntawm kev kho lub hauv paus, kev ya raws- pov thawj txheej, xaiv cov khoom siv thiab kev tswj xyuas kev tsim kho, tiv thaiv- kev kho qhov skid, thiab kev saib xyuas tom qab. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:

1, Grassroots kev kho mob: tso lub hauv paus rau kev tiv thaiv noo noo
Ntxuav thiab kho
Ua tib zoo tshem tawm cov dej slurry, roj stains, plua plav, thiab cov khoom xoob los ntawm cov txheej txheej hauv qab kom ntseeg tau tias tsis muaj dej seem.
Kho qhov tsis xws luag xws li cov kab nrib pleb thiab qhov los ntawm kev sau lawv nrog siab - cov ntaub ntawv kho lub zog (xws li epoxy mortar) kom tsis txhob muaj dej nkag mus.
Kev kho roughness
Polish los yog chisel lub hauv paus pob zeb txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam nws
2, Moisture pov thawj txheej tsim: thaiv noo noo infiltration
Siv cov dej noo- pov thawj txheej
Siv cov dej tshwj xeeb- cov ntaub ntawv pov thawj (xws li polyurethane waterproof coatings, cement-raws li permeable crystalline waterproof coatings) nyob rau saum npoo ntawm lub hauv paus txheej los ua ib tug nruam waterproof zaj duab xis, zoo thaiv qhov nce ntawm cov dej hauv av.
Cov txheej txheej yuav tsum tsis sib xws, nrog lub thickness uas ua tau raws li cov khoom yuav tsum tau (feem ntau ntau dua los yog sib npaug rau 1.5 hli), kom tsis txhob muaj omissions lossis tsub zuj zuj.
Ntxiv txheej ntawm waterproofing membrane (yeem)
Ntxiv ib txheej ntxiv ntawm cov ntaub thaiv dej tsis zoo ntawm cov dej xau xws li chav dej hauv pem teb thiab cov yeeb nkab hauv paus los txhim kho cov dej noo hauv zos.

3, Kev xaiv cov khoom siv thiab kev tswj xyuas kev tsim kho: Ua kom muaj kev sib npaug ntawm kev ya raws thiab kev ua haujlwm tsis zoo
Xaiv cov khoom siv tiv thaiv- zoo li qub terrazzo
Cov khoom siv hluav taws xob: Kev sib txuas cov khoom siv hluav taws xob (xws li carbon fiber) lossis cov hmoov hluav taws xob (xws li graphite) kom ntseeg tau tias qhov chaw tiv thaiv ntawm terrazzo ua tau raws li cov kev cai tiv thaiv zoo li qub (feem ntau tsawg dua lossis sib npaug li 1 × 10 ⁶ Ω).
Cov tshuaj tiv thaiv dej noo: Siv cov cement hydrophobic-raws li cov ntaub ntawv los yog ntxiv cov tshuaj tiv thaiv dej kom txo tau cov dej nqus dej ntawm terrazzo (pom zoo tsawg dua lossis sib npaug li 5%) thiab txhim kho nws cov impermeability.
Anti slip aggregate: Quartz xuab zeb, granite fragments, thiab lwm yam ntaub ntawv uas muaj nruab nrab roughness yog siv los ua aggregates los txhim kho qhov kev sib txhuam coefficient ntawm qhov chaw kom tsis txhob muaj qhov txo qis hauv cov nyhuv los ntawm kev sib txhuam zoo heev.
Kev tsim kho txheej txheem tswj
Kev teeb tsa ntawm kev faib cov strips: Txhim kho cov kab sib faib (xws li tooj liab strips, iav strips) raws li tus qauv tsim, kom ntseeg tau tias cov kev faib cov seams yog ncaj thiab ruaj khov los tiv thaiv cov kab nrib pleb los ntawm shrinkage deformation.
Pob zeb slurry paving:
Tswj qhov sib xws ntawm cov pob zeb slurry (tsawg dua lossis sib npaug li 60mm), sib npaug sib npaug ntawm cov tuab (10-15mm), thiab zam lub zos thickening lossis thinning.
Ob sab thiab cov ces kaum ntawm cov kab sib faib yuav tsum flattened thiab compacted kom tsis txhob hollowing.
Rolling thiab smoothing: Siv cov menyuam los ua kom sib haum thiab tshem tawm cov npuas, tom qab ntawd siv cov hlau trowel kom du nto, kom ntseeg tau tias qhov sib txawv ntawm qhov sib txawv yog tsawg dua lossis sib npaug li 2 hli.
4, Anti-slip kho: txhim khu kev nyab xeeb thaum siv
Nto ntxhib sib tsoo thiab anti slip agent kho
Tswj kom tsim nyog roughness thaum lub sij hawm sib tsoo ntxhib theem (60-80 # sib tsoo log) txhawm rau txhim kho kev ua haujlwm tsis zoo.
Tom qab kev tsim kho tiav lawm, siv cov tshuaj tiv thaiv tshwj xeeb terrazzo los tiv thaiv plam kom nce qhov sib txhuam coefficient los ntawm kev siv tshuaj lom neeg thaum tswj kev ya raws.
Slope tsim
Lub chav da dej hauv pem teb yuav tsum muaj qhov kev nqes hav uas tsim nyog (Ntau dua lossis sib npaug li 1%) kom ua kom cov dej ntws zoo thiab tsis txhob ntev - lub sij hawm ntub dej ntawm cov dej noo - cov ntaub ntawv pov thawj vim muaj dej sib xyaw.
5, Kev saib xyuas tom qab: Consolidate ya raws cov nyhuv
Moisturizing tu
Tom qab kev tsim kho tiav, npog nrog cov yas zaj duab xis los yog cov hnab ntim ntub dej kom cov av noo. Lub sij hawm kho yuav tsum siab dua los yog sib npaug li 7 hnub los txhawb cov cement hydration thiab txo qhov shrinkage tawg.
Wax sealing
Tom qab lub sijhawm txij nkawm tas lawm, siv cov khoom siv dej tsis zoo los yog epoxy resin txheej txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm
6, Kev lees paub zoo
Moisture resistance:
Kev nqus dej tsawg dua lossis sib npaug li 5% (kuaj raws li "Code rau Kev Txais Kev Tsim Kho Zoo ntawm Lub Tsev Hauv Tsev Engineering" GB50209).
Tsis muaj qhov xau tom qab 24 teev ntawm kev ntsuas dej kaw.
Anti-slip kev ua tau zoo:
Kev sib txhuam coefficient Ntau dua lossis sib npaug ntawm 0.6 (hauv cov dej ntub dej).
Lub ntsej muag zoo:
Qhov saum npoo yog tiaj tus, tsis muaj kab nrib pleb lossis xuab zeb qhov, qhov sib faib strips yog ncaj thiab meej, thiab cov xim zoo ib yam thiab zoo ib yam.
