1. Ua ntej-Kev Npaj Kev Txhim Kho
(1) Substrate Requirements
Lub substrate yuav tsum ua tau raws li plaub tus qauv tseem ceeb:firmness, flatness, dryness, thiab huv.
Qhob substrate: Yuav tsum muaj lub sijhawm kho yam tsawg kawg 28 hnub kom muaj kev ruaj ntseg ntawm cov qauv. Cov ntsiab lus noo noo yuav tsum yog qis dua 6% txhawm rau tiv thaiv kev sib txuas tsis ua haujlwm lossis kev nqa mosaic.
Ntoo substrate: Yooj yim rau ya raws deformation, yog li ntxiv cov dej tsis muaj dej (xws li, cov ntaub thaiv dej tsis zoo lossis cov txheej txheej) thiab cov khoom siv ntxiv (piv txwv li, plywood) yog qhov tsim nyog los txhim kho cov load-cov kabmob muaj peev xwm thiab tiv thaiv kev tawg.
(2) Kev suav cov khoom siv
Kev kwv yees cov khoom raug tiv thaiv tsis txaus lossis pov tseg:
Cov ntaub ntawv tseem ceeb: Ntxiv 10%-15% ntxiv rau qhov chaw tiag tiag kom suav rau kev txiav thiab kho qhov poob. Paub meej specifications thiab ntau npaum li cas ib square meter nrog lwm tus neeg.
Cov khoom siv pabcuam: suav nrogpebble mosaic-cov nplaum tshwj xeeb (kom muaj kev sib raug zoo thiab kev sib raug zoo), cov dej tsis sib haum (tshwj xeeb tshaj yog rau cov chaw ntub dej xws li chav dej thiab pas dej), thiab nkag mus rau sealer (los txhim kho stain resistance). Xam cov nyiaj raws li cov lus qhia khoom thiab qhov project loj.
2. Cov kauj ruam txhim kho kom ntxaws
Kev kho substrate
Ua tib zoo ntxuav lub substrate nrog ib tug txhuam los yog lub tshuab nqus tsev, ces so nrog ib daim ntaub ntub dej kom tshem tawm cov seem. Kho cov kab nrib pleb lossis kev nyuaj siab nrog cov cement mortar (pob zeb) lossis tshwj xeeb muab tub lim (ntoo). Tom qab ziab, xuab zeb saum npoo kom du thiab tsis muaj protrusions.
Layout Marking
Siv cov kab chalk los cim kab rov tav thiab ntsug raws li tus qauv tsim. Ua raws li cov kab xev xaim yog xav tau los xyuas kom meej qhov sib txawv thiab cov qauv raug (xws li, symmetry, qhov sib txawv qhov dav).
Daim ntawv thov Adhesive
Sib tov cov nplaum tshwj xeeb nrog dej raws li cov lus qhia kom txog thaum tus. Cia nws so rau 5-10 feeb, ces remix. Siv ib qho trowel (6-8mm hniav loj), siv cov nplaum ntawm lub kaum sab xis 45℃raws li cov lus qhia. Ua hauj lwm hauv 1-2 sqm seem kom tiv thaiv kom qhuav ntxov ntxov.
Mosaic Installation
Pib nteg mosaics raws li cov lus qhia, tswj qhov khoob (feem ntau 1-2mm). Rau cov qauv tsim, qhuav-ntev daim ua ntej kom paub meej seamless hloov thiab zam misalignment.
Compaction thiab Leveling
Maj mam coj mus rhaub rau saum npoo nrog cov roj hmab mallet kom ntseeg tau tias tag nrho cov adhesion thiab tshem tawm cov hnab ntim cua. Xyuas flatness nrog ib tug leveler thiab kho tej qhov chaw tsis sib xws tam sim.
Grouting
Tos 24 teev rau cov nplaum los kho. Siv cov dej tsis sib haum (xim - sib phim rau cov mosaic) nrog cov nplais pobzeb, txhaws qhov khoob kom tiav. Tshem tawm cov grout tshaj tam sim ntawd.
Kev Tu Nto
Tsis pub dhau 30 feeb ntawm grouting, so qhov chaw nrog ib daim txhuam cev ntub dej los yog daim ntaub mos muag ntawm qhov khoob kom tshem tawm cov khoom seem. Tsis txhob txhuam hnyav kom tiv thaiv kev puas tsuaj.
Kev tiv thaiv sealing
Tom qab qhov kev kho mob tag nrho (∼72 teev), siv lub tshuab nqus dej nrog cov txhuam mos los yog cov menyuam hauv ib qho kev coj ua. Cia thawj lub tsho tiv no kom qhuav (2-4 teev), tom qab ntawd siv lub tsho thib ob rau kev ua kom zoo dua qub thiab dej tsis kam.
3. Kev tu thiab tu
(1) Kev tu txhua hnub
Cov cuab yeej thiab cov tshuaj ntxuav: Siv pH- cov tshuaj tsis huv (pH 7-8) nrog cov ntaub mos mos, daim txhuam cev, lossis txhuam hniav. Tsis txhob siv cov cuab yeej abrasive xws li cov ntaub plaub los yog cov txhuam tawv tawv.
Tsis txhob acids/alkalis: Tsis txhob siv cov kua qaub (xws li, hydrochloric acid) los yog alkaline (xws li, xab npum muaj zog) cov tshuaj ntxuav tes, vim lawv tuaj yeem ua rau lub ntsej muag thiab ua rau lub sealant puas.
Txhaum teb: Tam sim ntawd tshem tawm cov dej nchuav (xws li kas fes, roj) nrog cov ntaub so ntswg thiab ntxuav nrog cov tshuaj ntxuav tes kom tsis txhob muaj qhov staining mus tas li.
(2) Kev saib xyuas tsis tu ncua
Kev rov ua dua tshiab: Rov muab cov ntaub nplaum nkag rau txhua 6-12 lub hlis (6 lub hlis rau qhov chaw ntub dej, 12 rau qhov qhuav) yog dej tsis muaj hlaws dai rau saum npoo.
Kev tshuaj xyuas Grout: Tshawb xyuas txhua 3-6 lub hlis kom pom cov kab nrib pleb, 脱落, lossis tsis muaj xim. Kho nrog waterproof grout kom tsis txhob ya raws infiltration.
Kev tiv thaiv lub cev: Zam tsis txhob cuam tshuam (piv txwv li, riam, cov khoom hlau). Siv cov ntaub mos muag hauv qab rooj tog kom txo qhov kev puas tsuaj.
(3) Kev daws teeb meem
Localized puas: Tshem tawm cov grout nyob ib ncig ntawm cov khoom puas, hloov nrog mosaics tshiab, regrout, thiab reseal kom sib xws.
Ua npaws: ntiav cov kws tshaj lij rau kev kho dua tshiab -lub teeb polishing kom tshem tawm oxidation, ua raws li kev rov ua dua kom rov qab ci.
Cov tawv nqaij tawv: Siv cov cuab yeej tshwj xeeb hauv kev sib sib zog nqus (kuaj kev sib tw ua ntej) rau cov stains nkag mus (xws li, number case, roj). Ua raws li cov lus qhia kom tsis txhob muaj kev puas tsuaj.
