Cov khoom siv hloov tau yooj yim, ib qho kev ua kom zoo nkauj tshiab ib puag ncig, sib txuas cov qauv ntawm ntuj nrog cov plasticity ntawm cov khoom siv hloov tau. Nws yog dav siv nyob rau hauv architectural sab hauv thiab sab nrauv phab ntsa kho kom zoo nkauj, kev tsim qauv tsim qauv, thiab lwm thaj teb. Nws cov cim tshwj xeeb thiab lub teeb ci ntsa iab muaj zog muab nws tseem ceeb zoo nyob rau hauv cov txheej txheem kev tsim kho nto. Cov ntsiab lus nram qab no txheem hloov pauv tau yooj yim Pob zeb tuav txoj kev los xyuas kom meej kev ua haujlwm zoo thiab tshwm sim.
I. Substrate Npaj
Ua ntej kev tsim kho, lub substrate yuav tsum tau tshuaj xyuas thiab npaj tau. Lub substrate yuav tsum yog tiaj, khoom, dawb ntawm hollows, tawg, lossis roj stains, thiab nws cov ntsiab lus noo yuav tsum tsawg dua 8%. Kev sib xyaw tsis ncaj yuav tsum tau kho nrog cov xis ntshiab los yog cov khoom siv tshwj xeeb qib kom ntseeg tau tias tsis muaj ntau tshaj 3mm. Yog hais tias lub substrate yog pob zeb lossis cugas cug, thov ib qho kev pom zoo tau pom zoo kom txhim kho adhesion.
Ii. Khoom npaj
Cov pob zeb hloov tau yog feem ntau muab rau hauv yob lossis cov ntawv txheeb thiab yuav tsum tau txiav rau cov qauv tsim ua ntej kev tsim kho. Siv cov cuab yeej txiav tshwj xeeb kom ntseeg tau cov npoo huv thiab tsis txhob muaj burrs uas yuav cuam tshuam rau cov nyhuv sib luag. Cov nplaum siv yuav tsum yog tus nplaum pob zeb yooj yim tshwj xeeb uas ua rau muaj kev sib xyaw nrog cov khoom siv hauv paus thiab lub pob zeb. Ua ntej thov, cov nplaum yuav tsum tau ua kom huv si thiab tso cai zaum rau 5-10 feeb kom tshem tawm cov pa npuas.
III. Daim ntawv thov paving
1.Apply cov nplaum: Siv ib qho chaw -} {}}}}}}}}}}}} Thov kev sib tw ntawm 2-3mm thiab qhov sib nrug muaj kwv yees li 15-20cm sib nrug.
2.LaLaying Pob Zeb: Dlhos lub pob zeb hloov tau thiab maj mam nias nws hauv qhov chaw. Siv cov roj hmab rauj lossis scraper kom du nws los ntawm nruab nrab sab nraud, tshem tawm cov hnab ris huab cua thiab ua kom muaj kev sib tw ua kom nruj.
3.Cougoecing: Tso pob zeb 2-3mm ntawm cov pob zeb nyob ib sab los pab txhawb nqa tom qab caulking. Siv cov caulk txuam lossis sib npaug kom txhim kho kom muaj kev zoo nkauj tag nrho.
IV. Post -} Kev Tu Xyuas
Tom qab daim ntawv thov, cia cov npoo mus zaum 24 teev kom ntseeg tau tias muaj kev sib raug zoo sib cog lus. Zam kev cuam tshuam hnyav lossis dej puas hauv 24 teev. Tom qab kev kho kom puv (feem ntau 48-72 teev), kev kho mob tom ntej xws li caulking, sanding, lossis xim ua tau.
Tus yuam sij rau kev siv pob zeb hloov cov lus dag hauv kev npaj ua ntu zus, kev xaiv nplaum, thiab kev tswj hwm ntawm cov txheej txheem tso khoom. Cov txheej txheem nruj me ntsis rau cov txheej txheem no ua kom zoo dua qub, hloov tau, ua tiav ntawm cov khoom, ua tiav siab- zoo nkauj ua kom zoo nkauj cuam tshuam.
