Kev sim 1: Muab ib tus cwj mem tso rau tom qab ntawm lub pob zeb. Yog hais tias tus number case yog sai sai dispersed thiab leached nyob txhua qhov chaw, nws txhais tau hais tias lub sab hauv ntawm lub pob zeb yog xoob thiab tsis zoo; Txawm li cas los xij, yog tias tus number case poob tsis nkag mus, lub pob zeb yog ntom thiab zoo.
Marble
Qhov tseeb, qhov no yog qhov kev sim yooj yim ntawm kev nqus dej ntawm pob zeb. Yog hais tias tus number case poob tsis nkag mus, nws yuav qhia tau hais tias qhov kev ntxhib los mos ntawm pob zeb yog qhov ntom ntom thiab cov dej nqus dej tsawg. Marble feem ntau yog coated nrog ib txheej ntawm tus neeg sawv cev tiv thaiv kom tsis txhob nkag mus ntawm stains. Txawm hais tias tus neeg siv khoom pom tias tus number case poob yog impermeable, nws zoo li tus neeg sawv cev tiv thaiv tau ua lub luag haujlwm, tsis yog kev ua haujlwm ntawm lub pob zeb nws tus kheej. Tsis tas li ntawd, yog tias cov dej nyob tom qab ntawm lub pob zeb yog nyob rau hauv daim ntawv ntawm cov hlaws dai, nws txhais tau hais tias nws yog ib qho nyuaj rau nqus dej thaum nws tau coated nrog tus neeg sawv cev tiv thaiv, uas kuj yuav ua rau nws tsis haum nrog cov cement. Yog li ntawd, nws tuaj yeem txiav txim siab tias qhov me me ntawm qhov nqus dej ntawm lub hauv ntej ntawm marble yog, qhov zoo dua. Txawm li cas los xij, nws yuav tsum tau txiav txim siab seb lub nraub qaum ntawm marble tuaj yeem sib raug zoo nrog cov cement adhesives.
Kev sim 2: vinegar yuav hnov mob nrog marble los tsim cov calcium acetate, yog li tso kua txiv hmab txiv ntoo ntawm marble yuav ua rau lub pob zeb hloov pauv thiab ntxhib, yog li peb tuaj yeem pom seb nws puas yog marble tiag.
Qhov kev sim no yog qhov tsim nyog, tab sis vim qhov tsis muaj zog acidity ntawm acetic acid nws tus kheej, qhov kev sim yuav tsum tau siv sijhawm ntev. Cov neeg siv khoom tsis tuaj yeem pom cov txiaj ntsig tau ib ntus, tab sis cov txiaj ntsig ntawm kev siv dilute hydrochloric acid yog qhov pom tseeb.
Kev sim 3: Kov lub pob zeb thiab xyuam xim rau lub suab. Yog tias lub suab meej meej, nws qhia tau tias cov khoom zoo yog qhov zoo, thiab sab hauv yog zoo thiab zoo li tsis muaj kab nrib pleb; Yog hais tias lub suab ntxhib, nws qhia tau hais tias muaj cov kab nrib pleb thiab xoob zoo nkauj hauv marble.
Qhov kev ntsuam xyuas no tsuas tuaj yeem qhia tau tias qhov kev ntxhib los mos ntawm pob zeb yog tawv, nkig thiab siab zog. Nws tsis tuaj yeem siv los ua tus qauv los txiav txim seb lub pob zeb zoo li cas, vim tias lub suab tsim los ntawm lub pob zeb muaj qee qhov kev sib raug zoo nrog nws ntau yam thiab loj. Hom marble no muaj lub zog siab dua yog haum rau hauv av.
