Cov xwm txheej zoo sib xws thiab kho cov txheej txheem ntawm Inorganic Sib tsoo pob zeb ntug kev puas tsuaj

Cov pob zeb sib tsoo tsis muaj zog (cement-raws li cov pob zeb sib tsoo) yog siv dav hauv kev kho kom zoo nkauj hauv pem teb thiab phab ntsa vim lawv cov tawv tawv thiab hnav zoo. Txawm li cas los xij, lawv nkig thiab muaj kev puas tsuaj ntawm cov npoo vim kev sib tsoo, thermal expansion thiab contraction, thiab kev tsim kho tsis raug. Cov hauv qab no muab cov lus piav qhia ntxaws los ntawm ob yam: kev puas tsuaj ntau thiab cov txheej txheem kho:

1, Kev puas tsuaj feem ntau ntawm inorganic sib tsoo pob zeb npoo
Lub kaum ntse ntse tawg: Thaum ntug cuam tshuam los ntawm sab nraud quab yuam (xws li rooj tog txav los yog cov khoom ntog), qhov sib koom ua ke ntawm cov cement puag thiab cov kab nrib pleb, tsim cov khoob me me los yog cov kab nrib pleb, uas yog hom kev puas tsuaj ntau tshaj plaws.
Peeling: Cov txheej txheej saum npoo (1-3mm) ntawm ntug sib cais los ntawm lub hauv paus txheej, feem ntau vim yog kev kho tsis raug ntawm lub hauv paus txheej (xws li tsis muaj plaub hau lossis roj stains), kev saib xyuas tsis txaus (tsis muaj zog los ntawm kev tsis txaus dej thaum ntxov), los yog dej noo mus ntev (dej nkag mus rau hauv daim ntawv cog lus tsis ua haujlwm).
Cov kab nrib pleb: Cov kab nrib pleb ntev los yog cov kab nrib pleb tshwm ntawm cov npoo, tshwm sim los ntawm thermal expansion thiab contraction (sib txawv expansion coefficients los ntawm cov ntaub ntawv uas nyob ib sab, tsis muaj expansion pob qij txha), hauv paus kev daws teeb meem (tsis sib xws hauv av, kev nyuaj siab hauv zos), los yog tsis muaj kev tsim kho pob qij txha.
Pores: Cov qhov me me tshwm sim ntawm cov npoo, feem ntau vim yog qhov tsis sib xws ntawm cov khoom sib sau ua ke (hauv zos tsawg dua aggregate, ntau cov cement, shrinkage tom qab ziab) los yog tsis tiav compaction ntawm cov ntaub ntawv thaum kho (cua tsis raug tshem tawm ua pores).
2, Inorganic sib tsoo pob zeb ntug kho txoj kev
Kev kho yuav tsum ua raws li cov txheej txheem tseem ceeb ntawm "kev tu → xim txuam → txhaws → kho → polishing", thiab ua raws li qhov xwm txheej:

(1) Lub kaum ntse ntse (qhov sib txawv me me, dav<5mm)
Cov ntaub ntawv / cov cuab yeej: inorganic sib tsoo pob zeb kho tus neeg saib xyuas (ua ke nrog cov xim qub), lub kaum sab xis (nrog pob zeb diamond sib tsoo disc), txhuam, txhuam, ntawv xuab zeb (240-600 mesh), dej, yas zaj duab xis (yeem).
Cov kauj ruam:

Ntxuav qhov chaw puas ntsoog: Siv lub kaum sab xis los txhuam cov npoo npoo tiaj tus, tshem tawm cov khoom xoob thiab cov plua plav ntab, ntxuav nrog txhuam, thiab ntub dej (tsis pom dej ntawm qhov chaw).
Kev sib tov kho tus neeg saib xyuas: Sib tov kho tus neeg saib xyuas (A: B Cheebtsam) raws li cov lus qhia, ntxiv me me ntawm inorganic pigment rau kev hloov xim (raws li cov xim qub ntawm cov pob zeb sib tsoo, thiab siv cov pob zeb sib tsoo thawj zaug los ua cov xim auxiliary hloov).
Sau qhov sib txawv: Siv lub scraper los sau qhov sib txawv nrog tus neeg saib xyuas kho, ua kom nws zoo, thiab du ntawm ntug (me ntsis siab dua li qhov qub, raws li tus neeg saib xyuas kho yuav ntsws).
Kev Kho: Npog nrog yas zaj duab xis ntawm chav tsev kub (5-35 degree) thiab tuav rau 24-48 teev (tsis txhob trampling thiab dej ntws).
Polishing: Tom qab kho, siv cov ntawv xuab zeb los txhuam los ntawm ntxhib kom zoo (240 grit kom tshem tawm qhov siab, 600 grit kom du), thiab thaum kawg siv cov pob zeb sib tsoo tshwj xeeb polishing tus neeg saib xyuas lossis siv quav ciab los kho cov luster.
(2) Peeling off (surface peeling, depth>3 hli)
Cov khoom siv / cov cuab yeej: kho tus neeg saib xyuas, tus neeg saib xyuas interface (xws li tus neeg saib xyuas epoxy), lub kaum sab xis, txhuam, txhuam, ntawv xuab zeb.
Cov kauj ruam:

Cleaning the base layer: Use an angle grinder to polish the peeling area to a solid base layer (exposing the cement base), remove loose layers, clean with a brush, and wet with water.
Brushing interface tus neeg saib xyuas: Siv tus neeg saib xyuas inorganic rau ntawm lub hauv paus polished thiab tev nto los txhim kho qhov adhesion ntawm tus neeg saib xyuas kho thiab lub hauv paus.
Xim puv: Kho tus neeg saib xyuas kho thiab sau qhov khoob raws li cov kauj ruam "kaum tawg", compact thiab du me ntsis saum npoo.
Kev saib xyuas polishing: Tom qab 24-48 teev ntawm kev saib xyuas, polish nrog 240-600 grit sandpaper kom rov qab tau cov luster.
(3) Crack (dav<2mm)
Cov khoom siv / cov cuab yeej: Inorganic grout (tsawg viscosity, siab zog), lub kaum sab xis grinder, txhuam, scraper, sandpaper, daim npog ntsej muag.
Cov kauj ruam:

Qhib V-shaped zawj: Siv lub kaum sab xis los qhib V- zoo li zawj raws qhov tawg (qhov tob 2-3mm, dav 3-5mm), tshem tawm cov khoom xoob, ntxuav nrog txhuam, thiab ntub dej.
Paste decorative paper: Muab cov ntawv zoo nkauj tso rau ntawm ob sab ntawm qhov tawg (kom tiv thaiv tus neeg kho kom tsis txhob kis kab mob ib puag ncig).
Grouting kho: Siv lub scraper los sau cov nplaum nplaum rau hauv V-zoo li zawj, compact nws, thiab du nto (me ntsis siab dua qhov qub nto).

Kev tu polishing: Tom qab 24 teev ntawm kev saib xyuas, rhuav tshem cov ntawv zoo nkauj thiab txhuam nws nrog cov ntawv xuab zeb (240-600 mesh) los kho nws cov luster.
(4) Qhov (qhov me me, txoj kab uas hla<5mm)
Cov ntaub ntawv / cov cuab yeej: kho tus neeg saib xyuas, lub kaum sab xis grinder, txhuam, scraper, sandpaper.
Cov kauj ruam:

Ntxuav lub qhov: txhuam cov npoo ntawm qhov nrog lub kaum sab xis kom tshem tawm cov khoom xoob, ntxuav nrog txhuam, thiab ntub dej.
Xim puv: Kho tus neeg saib xyuas kho thiab sau lub qhov raws li cov kauj ruam "kab tawg", compact thiab du me ntsis saum npoo.
Kev saib xyuas polishing: Tom qab 24-48 teev ntawm kev saib xyuas, polish nrog 240-600 grit sandpaper kom rov qab tau cov luster.
(5) Large area damage (missing corners>5 cm)
Cov khoom siv / cov cuab yeej: Inorganic sib tsoo pob zeb prefabricated blocks (sib piv nrog cov xim qub thiab sib sau), cov nplaum nplaum (marble nplaum), lub kaum sab xis grinder, txhuam, scraper, ntawv xuab zeb.
Cov kauj ruam:

Ntxuav lub hauv paus txheej: txhuam cov chaw puas rau hauv cov txheej txheem txheej, tshem tawm cov khaubncaws sab nraud povtseg, ntxuav nrog txhuam, thiab ntub dej.
Txiav cov blocks prefabricated: Txiav inorganic sib tsoo pob zeb prefabricated blocks raws li cov duab ntawm qhov kev puas tsuaj (me ntsis loj dua qhov chaw puas, ua kom muaj kev tiv thaiv).
Adhesive fixation: Siv cov txheej txheem nplaum (marble nplaum) nyob rau sab nraum qab ntawm lub hauv paus txheej thiab prefabricated thaiv, compact thiab kho txoj hauj lwm (ntxuav nrog thaj chaw ib puag ncig) tom qab pasting.
Kev sib koom ua ke: Tom qab 24 teev ntawm kev kho, siv lub kaum sab xis los txhuam cov ntug ntawm lub pob zeb prefabricated (seamlessly txuas nrog lub pob zeb sib tsoo thawj), thiab tom qab ntawd siv cov ntawv xuab zeb (240-600 mesh) los txhuam nws kom du thiab rov qab nws cov luster.
3, Kho kev ceev faj
Xim sib txuam: Ua ntej kho, muab cov pob zeb sib tsoo qub los yog cov khoom me me, sib tov nrog tus neeg saib xyuas kho (me me ntau zaus), sib piv cov xim ntawm cov blocks, thiab tom qab ntawd kho lawv ntau heev tom qab lawv nyob ze.
Kev tu ib puag ncig: kub 5-35 degree, av noo<85%, avoid direct sunlight and wind (plastic film can be used to cover and moisturize).
Expansion Joint Treatment: Tom qab kho, xyuas cov pob qij txha nyob ib puag ncig (dav 5-10mm). Yog tias lawv ploj lawm, lawv yuav tsum tau muab txiav rov qab thiab ntim nrog elastic sealant (xws li silicone sealant) kom tsis txhob tawg ntxiv.
Kev saib xyuas txhua hnub: Tsis txhob muaj cov khoom hnyav los tsoo cov npoo tom qab kho, tsis tu ncua siv quav ciab (txhua 3-6 lub hlis) los tiv thaiv qhov chaw thiab txo qhov hnav thiab tsim kua muag.
Los ntawm kev siv cov txheej txheem saum toj no, qhov teeb meem ntawm kev sib tsoo pob zeb ntug kev puas tsuaj tuaj yeem raug tsom los kho cov nyhuv zoo nkauj thiab siv tau.
