Kev siv cov iav ua kua rau cov plag tsev tsis muaj dej, nws cov yam ntxwv, qhov zoo thiab qhov tsis zoo, kev npaj saum npoo thiab thev naus laus zis ntawm kev siv cov tshuaj silicate tov rau nws. Ntxiv nrog rau cov npe muaj txiaj ntsig zoo, kev tiv thaiv hauv pem teb nrog cov iav kua muaj qee qhov tsis zoo:
- Ib puag ncig alkaline ntawm cov kua iav xav tau cov cuab yeej tiv thaiv thaum ua haujlwm nrog nws: tsom iav tshwj xeeb thiab hnab looj tes roj hmab.
- Vim yog lub sijhawm teeb tsa luv ntawm cov khoom siv hauv kev sib xyaw, cov txuj ci ntawm cov neeg ua haujlwm ua haujlwm yuav tsum muaj txaus txaus.
- Cov iav kua tsis pom zoo rau kev ua cov hauv paus cib, qhov no tuaj yeem ua rau nws puas tsuaj.
- Thaum cov iav ua kua tau thov hauv nws daim ntawv dawb huv rau hauv pem teb, nws ua rau lub ntsej muag du, uas qee cov ntaub ntawv ua tiav, xws li xim, yuav tsis ua zoo. Yog li, cov tshuaj khib nyiab feem ntau siv los ua tshuaj ntxiv rau cov cement sib tov lossis pob zeb ua ke.
Kev npaj saum npoo rau rwb thaiv tsev
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 lub cev Qhov no tuaj yeem ua tiav nrog txhuam txhuam, txhuam nrog cov ntawv txuas thiab tshuaj lom neeg.
Tom qab ntxuav tas, cov khib nyiab thiab hmoov av yuav tsum tau muab tshem tawm ntawm qhov chaw hauv pem teb. Txog kev ua haujlwm zaum kawg, koj tuaj yeem siv tsev neeg lossis lub tshuab nqus tsev muaj. Kev ntxuav hauv pem teb ua rau nws muaj peev xwm nthuav qhia tag nrho nws qhov tsis xws luag. Cov no suav nrog cov kab nrib pleb, nti, nthuav cov pob qij txha nthuav dav, thiab zoo li. Ib qho ntxiv, kev ua kom huv ntawm lub hauv paus ntxuav nws cov pores, uas txuas ntxiv ua kom tob tob hauv av hauv av nrog cov tshuaj tiv thaiv dej ntawm cov iav kua.
Pom cov kab nrib pleb thiab kev puas tsuaj zoo ib yam rau lub hauv paus yuav tsum tau ua tib zoo kho nrog kev tsim kho cov cement mortar. Qhov no yuav txo cov cua sov poob hauv chav thiab tiv thaiv cov plag tsev hauv qab no los ntawm kev xau.
Kev ua tiav ntxiv ntawm cov av hauv av yuav tsum tau ua los ntawm tus lej ntawm nws txoj kev ua tiav. Piv txwv li, cov tshuaj txhuam hniav tau thov kom ua kom tiav qib ntawm cov nplaim ntawm cov qauv rau kev pleev xim, thiab kev siv ua ntej yog siv los xyuas kom cov nplaum ntawm lub hauv paus mus rau cov khoom kom tau glued.
Cov lus qhia rau kev thov iav iav rau hauv pem teb
Ua ntej sau hauv av nrog iav iav, koj yuav tsum npaj cov cuab yeej thiab cov khoom tsim nyog. Rau kev ua haujlwm me me hauv ib puag ncig hauv tsev, koj yuav xav tau: lub thoob, lub laum nrog lub taub dej sib tov, txhuam lossis tshuaj tsuag xim, Portland MAAs, xuab zeb, dej, spatula thiab tag nrho.
Cov txheej txheem ntawm kev tiv thaiv dej hauv av muaj ob theem tseem ceeb: kev npaj cov tshuaj silicate thiab nws daim ntawv thov rau saum npoo.
Dilute kua iav hauv dej thiab sib tov nrog lwm cov khoom sib xyaw ua ke uas tau pom zoo rau qee yam haujlwm. Nrog txo cov nplaum ntawm cov tshuaj silicate rau hauv pem teb, koj tuaj yeem txo cov dej hauv qhov sib xyaw lossis nce cov ntsiab lus ntawm cov cement hauv nws. Tsuas yog dej txias tuaj yeem ntxiv rau iav kua. Txog nws qhov ntau npaum li cas, koj yuav tsum siv ntsuas lub ntim ntawm qhov xav tau ntim.
Txhawm rau kom tau txheej txheej tsis muaj dej, nws yog qhov tsim nyog yuav tsum tau siv cov khoom sib xyaw ua ke hauv qhov sib piv ntawm 1:10, uas yog, 10 liv ntawm cov pob zeb lossis cov tshuaj khib yuav tsum tau ntxiv rau ib litre ntawm cov kua iav. Ua ntej, cov cement thiab cov xuab zeb yuav tsum tau sib xyaw nrog dej, thiab tom qab ntawd ntxiv iav ua kua rau qhov sib xyaw ua ke. Txhawm rau muab cov khoom sib tov sib xyaw rau hauv ib lub taub ntim, siv lub laum nrog cov khoom sib tov sib xyaw.
Cov tshuaj silicate npaj yuav tsum tau nchuav mus rau lub screed hauv daim ntawv ntawm cov khoom sib npaug hauv cov kab ib puag ncig sib luag rau ntawm phab ntsa. Tom qab ntawd, siv cov spatula dav, cov khoom sib xyaw yuav tsum tau muab faib sib npaug ntawm lub dav hlau hauv av. Tom qab qib sib tov sib xyaw, qhov saum npoo yuav tsum tau kho nrog rab koob rau menyuam, siv nws tshem tawm cov npuas thiab qhov tsis sib xws me me hauv txheej.
Ib txheej ntawm rwb thaiv tsev yuav tsum ua tiav hauv ib kis. Nws cov tuab yuav tsum yog 3-5 hli. Hauv cov txheej txheem ua haujlwm, koj yuav tsum xyuas kom tsis muaj thaj chaw uas tsis kho nrog tshuaj khib rau hauv pem teb. Nws yuav siv sijhawm qee lub sijhawm rau cov kua iav nkag mus rau hauv qhov hws thiab microcracks ntawm qhov chaw. Yog li ntawd, txheej txheej thib ob thiab tom qab yuav tsum tau siv nyob rau ntawm 0.5 teev.
Qee zaum cov kua iav tau siv rau hauv pem teb thaum sib xyaw cov tshuaj screed. Hauv qhov no, txoj haujlwm yuav tsum tau ua sai sai, vim qhov sib xyaw ua kom tawv tawv heev.
Tom qab cov txheej txheej txheej txheej tiv thaiv dej tau qhuav tag, nws tuaj yeem kho nrog epoxy lossis polyurethane-based varnish. Nyob rau tib lub sijhawm, saum npoo yuav tau txais ci, pob tshab thiab ntxiv dag zog. Ib hnub tom qab ua haujlwm tas, nws yuav tuaj yeem taug kev hauv pem teb.
Yuav ua li cas npog hauv av nrog iav iav - saib cov vis dis aus:
Dua li ntawm qhov tseeb tias niaj hnub no kev tsim kho kev lag luam muaj ntau yam kev sib xyaw insulating niaj hnub no, kua iav tseem yog cov khoom siv nrov vim nws muaj ntau yam. Qhov tseeb, ntxiv rau kev tiv thaiv cov plag tsev, nws tau nquag siv los tiv thaiv cov tso tsheb hlau luam, lub qhov cub tawg thiab lwm qhov chaw ntawm kev tsim kho. Lub tshuab siv cov khoom no tsis nyuaj tshwj xeeb. Qhov tseem ceeb hauv nws yog ua raws li cov lus pom zoo cuam tshuam nrog kev nyab xeeb ntawm kev siv iav ua kua thiab kev ua raws ntawm kev faib ua feem hauv kev tsim cov khoom sib xyaw silicate.
