Yuav ua li cas kho cov kauj ruam hauv zos hollowing los yog tawg hauv terrazzo slabs? Yuav ua li cas kom tsis txhob muaj xim txawv?

Kho cov kauj ruam rau hauv zos hollowing los yog tawg nyob rau hauv terrazzo slabs
1, Cov kauj ruam rau kev kho lub zos hollowing
Txoj hauj lwm thiab tu
Siv ib tug me me rauj maj mam coj mus rau hauv av, txiav txim siab qhov hollow cheeb tsam los ntawm lub suab, thiab kos lub ntau yam.
Tshem tawm cov plua plav, roj stains, thiab cov khoom xoob ntawm qhov chaw ntawm qhov khoob kom ntseeg tau tias qhov chaw kho kom qhuav thiab tsis muaj impurities. Yog tias lub ntug ntawm lub nruas hollow yog nruj nreem txuas rau hauv av tsis zoo, lub tshuab txiav yuav tsum tau siv los txiav cov duab tsis tu ncua (xws li cov duab plaub) raws tus ciam teb ntawm lub nruas hollow, nrog rau kev txiav qhov tob me ntsis siab dua qhov siab ntawm lub nruas hollow (feem ntau yog 5-10mm), kom tsis txhob ua rau lub hauv paus txheej.
kev kho mob hauv paus
Tshawb xyuas lub zog ntawm lub hauv paus txheej. Yog hais tias lub hauv paus txheej yog xoob los yog muaj kab nrib pleb, nws yuav tsum tau muab tshem tawm mus rau ib tug khoom txheej thiab kho nrog cement mortar kom nws du.
Ntxuav qhov txiav substrate nrog lub siab - rab phom cua los yog txhuam kom paub tseeb tias tsis muaj hmoov av ntab.
Filling khoom xaiv thiab kev tsim kho
Cov cheeb tsam me me hollowing: Siv epoxy resin putty los yog tshwj xeeb kho tus neeg saib xyuas uas zoo ib yam li xim rau cov thawj terrazzo. Tom qab sib tov sib xyaw cov ntaub ntawv raws li qhov kev faib ua feem, sau lub hollow cheeb tsam thiab siv ib tug scraper kom compact thiab du, kom ntseeg tau tias nws yog theem nrog thawj av.
Loj cheeb tsam hollowing: txoj kev grouting yog siv. Laum qhov (nrog rau txoj kab uas hla ntawm 6-8mm thiab qhov sib nrug ntawm 300-500mm) nyob rau hauv qhov chaw hollow, nruab grouting nozzles, thiab kaw cov phaj pob qij txha. Siv lub tshuab ua kom lub zog siab kom txhaj cov viscosity tsawg, lub zog siab grouting resin rau hauv lub nruas hollow kom txog thaum cov slurry puv thiab tsis muaj dej ntws. Tom qab grouting, npog thaj chaw kho nrog ib daim ntaub ntub dej thiab ua kom nws ntub rau 3-7 hnub.
kho saum npoo
Tom qab ua tiav qhov pib ntawm cov khoom siv, siv lub log sib tsoo los yog cov ntawv xuab zeb los txhuam qhov chaw kho kom nws ua tau raws li qhov qub nto tiav.
Yog tias qhov sib txawv ntawm cov xim yog pom tseeb, siv cov xim pleev xim uas phim cov xim hauv av hauv zos, thiab txhuam nws tom qab ziab.

2, Kho cov kauj ruam
Kev ntsuam xyuas tawg
Cov kab nrib pleb me me uas muaj qhov dav tsawg dua 0.3 hli tuaj yeem ua tiav ncaj qha nrog epoxy resin nplaum los yog cement tawg muab tshuaj txhuam.
Cov kab nrib pleb uas muaj qhov dav Ntau dua lossis sib npaug li 0.3 hli: V- cov grooves (qhov tob Ntau dua lossis sib npaug li 10 hli) yuav tsum tau txiav raws qhov tawg, thiab tom qab tshem cov khib nyiab, lub hauv paus txheej yuav tsum tau ntxiv nrog cov hlau xaim mesh, thiab tom qab ntawd nchuav nrog cov cement mortar lossis epoxy resin.
Kho cov khoom siv
Epoxy resin adhesive kho: Sib tov epoxy resin thiab curing tus neeg sawv cev hauv kev faib ua feem, do tusyees, sau cov kab nrib pleb, thiab siv lub scraper kom compact thiab du. Yog tias qhov tawg yog qhov sib sib zog nqus, nws tuaj yeem sau rau hauv cov theem, nrog lub sijhawm ntawm 2-4 teev ntawm txhua qhov txhaws.
Cement mortar kho: Siv tus neeg sawv cev cuam tshuam hauv cov kab nrib pleb los txhim kho kev sib raug zoo. Sau cov kab nrib pleb nrog cov cement mortar (dej cement ratio Tsawg dua lossis sib npaug li 0.4), compact nrog vibrating pas nrig, du nto, thiab npog nrog yas zaj duab xis rau 7 hnub ntawm kev kho.
kho saum npoo
Tom qab cov khoom kho kom ruaj khov, siv lub log sib tsoo los txhuam thaj tsam tawg thiab ua kom nws hloov mus rau qhov qub av.
Yog tias xav tau kev kho kom zoo nkauj ntxiv, cov xim pleev xim lossis terrazzo tshwj xeeb txheej uas phim cov xim hauv pem teb tuaj yeem siv tau.

3, Kev ntsuas tseem ceeb kom tsis txhob muaj xim sib txawv
Kev xaiv cov khoom siv thiab sib xyaw
Kev tswj cov khoom raw: Xaiv cov pob zeb mined los ntawm tib txoj hlab ntsha kom paub meej cov xim zoo ib yam thiab qhov loj me. Kev yuav khoom kom muaj nuj nqis rau txhua batch yog tswj ntawm 30-50 tons kom tsis txhob sib xyaw cov khoom los ntawm cov khoom sib txawv.
Pigment matching: Thaum kho, siv tib hom thiab qauv ntawm cov xim raws li cov hauv paus ntsiab lus, thiab xyuas kom meej xim sib xws los ntawm cov xim sib piv (Δ E Tsawg dua los yog sib npaug rau 1.5). Yog tias cov av qub yog sib xyaw ntawm ntau cov xim, cov ntaub ntawv kho yuav tsum tau muab sib xyaw ua ke raws li qhov qub.
Kev tsim kho txheej txheem optimization
Kev tsim kho txheej txheem: Thaum kho, ua ntej siv cov txheej txheej primer nrog cov xim zoo ib yam li cov hauv av qub, tom qab ntawd sau cov khoom siv kho, thiab thaum kawg ua qhov kev kho saum npoo kom txo cov xim sib txawv.
Kev tswj teeb pom kev zoo: Kev tsim kho ib puag ncig illumination yuav tsum siab dua lossis sib npaug ntawm 1000lux kom tsis txhob muaj xim kev txiav txim siab yuam kev los ntawm lub teeb tsis txaus. Tom qab kho, tsis txhob raug tshav ntuj ncaj qha los tiv thaiv lub zos fading.
Cov txheej txheem kho xim sib txawv
Acid ntxuav cov xim txhim kho: Soak thaj chaw kho hauv 5% oxalic acid tov rau 20 feeb kom tshem tawm cov tshuaj alkaline thiab txhim kho xim saturation. Tam sim ntawd yaug nrog dej huv thiab neutralize tus nqi pH rau 7.0 ± 0.5 tom qab ntxuav cov kua qaub.
Crystallization sealing kev kho mob: Silicon dioxide nano txheej (thickness Tsawg dua los yog sib npaug li 5 μ m) yog siv los kaw qhov chaw kho, stabilizing qhov sib txawv xim Δ E tus nqi ntau dua los yog sib npaug rau 98% thaum txhim kho hnav tsis kam.
Kev Ntsuam Xyuas Zoo thiab Kev Kho Kom Zoo
Qauv ua ntej tso: Npaj 1: 1 cov qauv rau txhua 1000 square metres ntawm thaj chaw tsim kho, thiab ua qhov kev soj ntsuam spectral (qhov sib txawv ntawm qhov sib txawv tsawg dua lossis sib npaug li 3%) tom qab 7 hnub ntawm kev kho kom ntseeg tau cov xim sib xws ua ntej loj - nplai siv.
Kev saib xyuas tsis tu ncua: Tom qab kho tiav, tsis tu ncua siv cov tshuaj ntxuav tshwj xeeb los ntxuav hauv pem teb thiab tsis txhob stains los ntawm kev nkag mus thiab ua rau muaj xim sib txawv. Kev kho waxing lossis crystallization yuav tsum tau nqa tawm txhua 2-3 xyoos kom tswj tau qhov zoo nkauj ntawm lub ntsej muag.
