Lub hauv paus granite yog ib yam khoom siv nrov siv rau hauv kev tsim cov khoom siv ua duab. Qhov laj thawj tseem ceeb rau qhov no yog vim nws qhov kev ruaj khov thiab kev siv tau ntev. Cov yam ntxwv no ua rau granite yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom siv ua duab uas xav tau kev ua kom raug, kev ruaj khov, thiab kev ntseeg tau.
Yuav kom tswj tau qhov chaw ua haujlwm ntawm cov khoom siv ua duab, nws yog ib qho tseem ceeb kom ua tau raws li qee qhov yuav tsum tau ua. Cov hauv qab no yog qee qhov yuav tsum tau ua:
1. Kev Tswj Kub: Qhov chaw ua haujlwm ntawm cov khoom siv ua duab yuav tsum khaws cia rau qhov kub thiab txias sib xws. Qhov no yog kom ntseeg tau tias lub hauv paus granite tseem ruaj khov thiab tsis nthuav dav lossis cog lus vim qhov kub thiab txias hloov pauv. Qhov kub zoo tshaj plaws rau granite yog nyob ib puag ncig 20 ° C txog 25 ° C.
2. Kev Tswj Xyuas Dej Ntswg: Nws yog ib qho tseem ceeb kom tswj tau qhov chaw ua haujlwm qhuav rau cov khoom siv ua duab. Qhov no yog vim tias dej noo tuaj yeem ua rau granite nqus dej uas tuaj yeem cuam tshuam rau nws qhov ruaj khov thiab ua rau nws tawg lossis warp. Qhov dej noo zoo tshaj plaws rau kev tswj hwm qhov chaw ua haujlwm ruaj khov yog ntawm 35% thiab 55%.
3. Kev Huv Si: Qhov chaw ua haujlwm ntawm cov khoom siv ua duab yuav tsum huv si, tsis muaj hmoov av thiab av qias neeg. Qhov no yog vim tias cov khoom me me uas nyob rau ntawm lub hauv paus granite tuaj yeem khawb qhov chaw thiab ua rau cov khoom puas tsuaj.
4. Kev Tswj Kev Co: Kev co tuaj yeem ua rau lub hauv paus granite txav mus los, cuam tshuam rau kev ruaj khov ntawm cov khoom. Nws yog ib qho tseem ceeb kom ntseeg tau tias qhov chaw ua haujlwm tsis muaj qhov chaw co xws li cov tshuab hnyav lossis tsheb khiav.
Yuav kom tswj tau qhov chaw ua haujlwm ntawm cov khoom siv ua duab, nws yog ib qho tseem ceeb uas yuav tsum tau ua kev saib xyuas tsis tu ncua. Kev saib xyuas kom zoo yuav tsis tsuas yog ua kom muaj kev ruaj khov thiab kev ua haujlwm ntev ntawm lub hauv paus granite tab sis kuj ua kom muaj kev ua haujlwm zoo tshaj plaws ntawm cov khoom. Cov lus qhia hauv qab no yog qee cov lus qhia txog kev saib xyuas uas tuaj yeem siv tau:
1. Kev Ntxuav Tsis Tu Ncua: Yuav tsum so lub hauv paus granite kom huv si kom tshem tawm cov hmoov av lossis av uas yuav tau sib sau ua ke. Siv daim ntaub mos mos lossis txhuam uas tsis txhuam tau los ntxuav qhov chaw.
2. Kev Siv Tshuaj Sealant: Kev siv tshuaj sealant rau ntawm lub hauv paus granite txhua ob peb xyoos tuaj yeem pab tswj nws qhov ruaj khov. Cov tshuaj sealant yuav pab tiv thaiv granite ntawm cov dej noo thiab lwm yam uas tuaj yeem ua rau puas tsuaj.
3. Tsis txhob hnyav dhau: Qhov hnyav dhau lossis kev ntxhov siab ntau dhau rau ntawm lub hauv paus granite tuaj yeem ua rau nws tawg lossis warp. Nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom tsis muaj qhov hnyav lossis kev ntxhov siab ntau dhau.
Xaus lus, qhov yuav tsum tau ua ntawm granite base rau cov khoom siv ua duab ntawm qhov chaw ua haujlwm yog kev tswj qhov kub thiab txias, kev tswj dej noo, kev huv, thiab kev tswj kev co. Txhawm rau kom tswj tau qhov chaw ua haujlwm, kev ntxuav tas li, kev siv sealant, thiab kev zam qhov hnyav ntau dhau tuaj yeem siv tau. Kev ua tau raws li cov kev cai no thiab kev ua haujlwm tas li yuav pab kom ntseeg tau tias cov khoom siv ua duab ruaj khov, ruaj khov, thiab kev ua haujlwm zoo tshaj plaws.
