Vim li cas Terrazzo Slabs xav tau kev faib cov sawb thaum siv hauv av? Lub luag haujlwm ntawm Grid Bar yog dab tsi?

Thaum lub sij hawm kev tsim kho ntawm terrazzo slabs rau hauv av, faib strips yog tsim los ntawm lawv cov khoom siv thiab kev tsim kho. Lub luag haujlwm tseem ceeb ntawm kev faib cov strips tuaj yeem raug sau tseg rau hauv plaub lub ntsiab lus hauv qab no:

1, Tiv thaiv qhov tshwm sim ntawm qhov tsis sib xws
Thaum lub sij hawm tsim kho thiab ziab, cov ntaub ntawv terrazzo tuaj yeem ua rau tsis sib xws vim muaj qhov hloov pauv kub, dej evaporation, lossis kev sib haum xeeb hauv paus. Yog hais tias hauv av yog nchuav tag nrho, qhov concentration ntawm shrinkage stress tau yooj yim ua rau loj - nplai tawg, uas yuav nkag mus rau tag nrho hauv av thiab cuam tshuam rau kev nyab xeeb thiab zoo nkauj ntawm cov qauv. Daim phiaj kab sib faib hauv av rau hauv thaj chaw me me (xws li kab sib chaws), txwv qhov kev sib txawv ntawm txhua qhov thaiv thiab cuam tshuam kev ntxhov siab rau cov cheeb tsam hauv zos, yog li txo qhov tshwm sim ntawm cov kab nrib pleb. Txawm hais tias cov kab nrib pleb tshwm sim, lawv raug txwv rau cov blocks me me faib los ntawm kab sib chaws, zam kev nthuav dav ntawm cov kab nrib pleb mus rau thaj chaw uas nyob ib sab.

2, Yooj yim rau kev tu thiab hloov hauv zos
Tom qab siv sijhawm ntev -, cov plag tsev terrazzo tuaj yeem ntsib kev puas tsuaj hauv zos (xws li hollowing thiab cracking) vim hnav, cuam tshuam, los yog teeb meem substrate. Yog tias tsis muaj kab sib chaws rau hauv av, qhov kev puas tsuaj tuaj yeem cuam tshuam rau thaj chaw loj, thiab tag nrho cov txheej txheem kho yuav tsum tau muab tshem tawm thiab rov ua dua, uas yog kim thiab siv sij hawm- siv. Daim phiaj sawb faib cov av rau hauv cov khoom me me, thiab thaum puas lawm, tsuas yog qhov chaw sib raug zoo yuav tsum tau kho yam tsis muaj kev puas tsuaj rau tag nrho cov qauv. Kev kho kom meej meej, kev ua haujlwm yog yooj yim, thiab nws tuaj yeem txo cov nqi kho mob.

3, Txhim kho av flatness thiab kev tsim kho raug
Thaum lub sij hawm tso cov txheej txheem ntawm terrazzo, me ntsis unevenness yuav tshwm sim nyob rau hauv av vim cov khoom tsis raug, kev tsim kho, los yog flatness ntawm lub hauv paus txheej. Daim phiaj kab tuaj yeem siv los ua cov cuab yeej hloov kho kom ua tiav qhov khoob lossis ua kom zoo nkauj qhov siab, them nyiaj rau kev tsim kho yuam kev thiab ua tiav qhov siab dua hauv av. Tsis tas li ntawd, qhov chaw ruaj khov ntawm daim phiaj sawb (xws li embedded raws li tus qauv number case kab) tuaj yeem pab tswj kev tsim kho qhov siab, kom ntseeg tau tias qhov kev nce siab zoo ib yam thiab txhim kho kev tsim kho kom zoo.

4, Txhim khu kev zoo nkauj thiab kho kom zoo nkauj
Daim phiaj strips tsis yog tsuas yog cov khoom siv ua haujlwm xwb, tab sis kuj tseem tuaj yeem ua cov khoom zoo nkauj. Los ntawm kev xaiv cov kab hluav taws xob ntawm cov khoom sib txawv (xws li tooj liab, txhuas, iav) lossis xim, cov qauv geometric, ciam teb, lossis ib cheeb tsam tuaj yeem muab faib ua kom muaj txiaj ntsig zoo hauv av. Piv txwv li, nyob rau hauv cov chaw pej xeem, daim phiaj kab tuaj yeem siv los faib cov chaw ua haujlwm (xws li txoj kev hauv tsev thiab cov chaw so), los yog kev sib koom tes nrog kev kho kom zoo nkauj tag nrho, txhim kho kev nkag siab ntawm kev tsim qauv.

Khoom siv thiab kev tsim cov ntsiab lus ntawm kev faib cov strips
Kev xaiv cov khoom siv: Feem ntau siv tooj liab, txhuas, lossis iav strips yuav tsum muaj kev tiv thaiv corrosion thiab cov yam ntxwv siab zog kom hloov mus rau qhov chaw siv terrazzo.
Txoj kev tsim kho:
Pop li faib cov kab ntawm cov txheej txheem tswj kom zoo;
Txiav thiab faib daim phiaj raws li txoj kab, thiab kho nws nrog cov cement slurry (hauv qab yog smoothed rau hauv daim duab yim zoo);
Xyuas kom meej tias daim phiaj strips ruaj khov, cov pob qij txha nruj, thiab tsis muaj qhov khoob;
Tom qab kev tsim kho, tuav tsawg kawg 2 hnub kom tsis txhob xoob ntawm cov kab sib faib.
Ceeb Toom: Qhov dav ntawm qhov sib faib sawb yuav tsum zoo ib yam kom tsis txhob cuam tshuam qhov tsos; Thaum lub sij hawm tsim kho, nws yog ib qho tsim nyog los tswj qhov siab ntawm cov cement slurry los xyuas kom meej tias cov sawb faib yog theem nrog hauv av.
