Dab tsi yog Cov Kev Txiav Txim Rau Kev Xaiv Pob Zeb?

Pob zeb yog siv nyob rau hauv lub tshav pob ntawm architectural kho kom zoo nkauj. Piv nrog rau lwm cov khoom siv kho kom zoo nkauj, nws qhov tseem ceeb tshaj plaws yog tias pob zeb yog cov ntxhia hauv ntuj thiab muaj cov khoom zoo nkauj tshwj xeeb ntawm cov xim, kev ntxhib los mos, qauv thiab hardness. Ntxiv nrog rau hom thiab xim ntawm pob zeb, tus nqi, zoo thiab kav ntev ntawm lub pob zeb kuj tseem ceeb heev:

1. Pob zeb nqe

Pob zeb yog tej yam ntuj tso minerals. Cov qib sib txawv ntawm cov pob zeb muaj cov nqi sib txawv vim lawv qhov zoo, ntau, thaj chaw mining thiab kev siv tshuab. Qhov no xav kom cov tswv thiab cov tsim qauv xaiv lub pob zeb zoo raws li qhov project pob nyiaj siv. Ua li no, koj yuav tsum muaj kev nkag siab zoo txog tus nqi ntawm pob zeb. Tam sim no cov neeg siv pob zeb feem ntau tau nkag mus rau qhov tsis to taub: pob zeb uas muaj nqi siab yog lub pob zeb zoo, lossis cov pob zeb txawv teb chaws yog qhov zoo dua li pob zeb hauv tsev.

Tau kawg, nws yuav tsum tau lees paub tias cov pob zeb xiav xiav, Indian liab thiab lwm yam pob zeb muaj cov yam ntxwv zoo nkauj tshwj xeeb thiab cov teebmeem zoo nkauj tsis tuaj yeem hloov tau. Tab sis peb kuj yuav tsum pom: Dahua Ntsuab, Baoxing Dawb, Dub thiab Dawb, Yixing Kas fes, Tuam Tshoj Dub, Fengzhen Dub thiab lwm yam pob zeb hauv tsev tsis yog phem dua li cov pob zeb txawv teb chaws, xws li Brazil dawb, imperial pob zeb, dub granite, thiab txawm tias qee hom. yog zoo dua li cov khoom lag luam.

Yog tias peb sib piv cov nqi ntawm cov ntau yam no, nws tsis yooj yim pom tias tus nqi ntawm cov khoom tuaj txawv teb chaws yog 3 mus rau 5 npaug ntawm cov khoom zoo sib xws hauv Suav teb. Yog li vim li cas peb cov neeg siv khoom tsis xaiv cov pob zeb zoo thiab pheej yig hauv tsev?

2. Pob zeb zoo

Xim: Ntxiv nrog rau kev zam ntawm kev siv pob zeb nrog pom tseeb xim sib txawv, kev siv cov xim pob zeb yuav tsum zam.

Cov pob zeb muaj pes tsawg leeg: Ib qho yog kom tsis txhob siv cov khoom siv pob zeb nrog cov ntsiab lus siab ntawm cov hlau sulfide, ntsev, carbon, av nplaum, thiab lwm yam; thib ob, kom tsis txhob siv cov khoom siv pob zeb thiab cov khoom siv thermally conductive nrog kev nthuav dav coefficients siab.

3. Kev pab lub neej thiab kav ntev

Pob zeb nyob hauv txoj haujlwm siab hauv cov khoom siv kho kom zoo nkauj thiab muaj cov khoom zoo nkauj irreplaceable. Feem ntau siv rau" facade" ntawm lub tsev, tus tswv cia siab tias lub pob zeb muaj qhov tseem ceeb ntawm lub tsev. Pob zeb nrog zoo durability tsis tau tsuas yog xyuas kom meej qhov zoo nkauj ntawm lub tsev, tab sis kuj prolong lub renovation voj voog ntawm lub tsev. Yog li ntawd, thaum pob zeb siv los ua cov khoom siv kho kom zoo nkauj rau sab nrauv phab ntsa, hauv pem teb thiab cov chav, cov nram qab no ntawm pob zeb yuav tsum tau tshawb xyuas:

1. Lub cev muaj zog. Pob zeb yuav tsum tiv taus ntau lub zog sab nraud, suav nrog lub ntiajteb txawj nqus, cua, kev co, kub hloov, hnav thiab thauj khoom. Qhov no yuav tsum muaj lub zog ntawm lub pob zeb siab heev, tshwj xeeb tshaj yog cov pob zeb ntsia ntawm qhov chaw siab.

2. Cov khoom siv tshuaj. Lub pob zeb yuav tsum muaj kev tiv thaiv zoo rau cov tshuaj tua kab mob xws li huab cua, dej, tawg, lub cev qhuav dej, acidification, txo qis thiab carbonate. Rau qhov no, lub pob zeb yuav tsum tsis muaj dej.

3. Lub zog muaj zog. Thaum xaiv cov pob zeb taw qhia xws li slate thiab shale, yuav tsum tau them nyiaj rau lub zog ntawm cov txheej txheem sib txawv.

4. Kev nqus dej. Cov qauv molecular ntawm lub pob zeb yog qhov ruaj khov thaum nws raug mined, tab sis thaum raug rau huab cua, cov ntxhia hauv pob zeb muaj kev sib koom ua haujlwm tsis zoo. Piv txwv li, thaum limestone ntsib cov kua qaub (cov tshuaj tiv thaiv cov khoom ntawm sulfite gas thiab dej), nws dissolves thiab tsim calcium sulfate rau ntawm qhov chaw, ua rau Sandstone vau, thiab lwm yam. Yog li ntawd, thaum xaiv pob zeb, sim xaiv pob zeb nrog uniform pore faib, me pore loj thiab tsawg nqus dej.
