1. Ua ntej, paub qhov txawv ntawm "cov khoom siv raw" thiab "cov khoom tiav": Bluestone yog cov ntsiab lus dav dav rau cov pob zeb ntuj, feem ntau yog hais txog bluish - grey limestone lossis sandstone. Nws yog ib qho uas tsis tau ua tiav, pob zeb nyoos uas khaws nws cov kev ntxhib los mos. Bluestone slabs, ntawm qhov tod tes, yog cov slabs tiav lawm uas tau txiav, polished, thiab lwm yam. Lawv muaj qhov du, feem ntau yog 2-5cm tuab, thiab feem ntau yog siv rau thaj tsam loj. Yooj yim tso: bluestone yog "cov khoom siv raw," thaum bluestone slabs yog "cov khoom tiav tiav."
2. Sib piv los ntawm peb qhov loj me:
① Cov yam ntxwv ntawm cov khoom siv: Bluestone (raws li cov khoom siv): Ib txwm tsim, nrog cov qauv tsim tshwj xeeb (cov qauv dej khov ua ke, cov qauv dej ripple), nruab nrab hardness, huab cua -resistant tab sis nrog ib qho xim (feem ntau yog xiav - grey), yuav tsum tau ua haujlwm thib ob tom qab quarrying.
Bluestone slabs (cov khoom tiav): Ua tiav los ntawm bluestone lossis lwm lub pob zeb, nrog rau qhov chaw ntau dua thiab cov xim tsis sib xws (feem ntau txhim kho los ntawm dyeing lossis polishing). Hardness thiab hnav tsis kam sib txawv nyob ntawm qhov kev siv tshuab. Qhov ntau thiab tsawg muaj xws li 60 × 60cm thiab 80 × 80cm.
② Cov xwm txheej siv tau
Bluestone (raw khoom): Tsim nyog rau me me - kho kom zoo nkauj hauv cheeb tsam, xws li cov pob zeb carvings, lub tshav pob zeb, cov rooj pob zeb thiab cov rooj zaum (natural textures tsim ib qho chaw).
Bluestone slabs (cov khoom tiav): Ntau qhov tsim nyog rau thaj chaw loj - paving, xws li cov plag tsev, chaw ua si, thiab villa sab nrauv phab ntsa (nplaum du, yooj yim rau nruab, kev tsim kho sai).
3. Cov neeg zoo tib yam yuav tsum xaiv li cas?
① Cov peev nyiaj tsawg + loj- thaj chaw paving: Xaiv cov pob zeb bluestone (ua ntej cov khoom siv bluestone ua ntej, ntsuas kev ntxhib los mos thiab nqi).
② me me- thaj chaw kho kom zoo nkauj + cov kev xav tau ntawm tus kheej: Xaiv bluestone (rau pob zeb carvings lossis toj roob hauv pes embellishments, ntuj thiab tshwj xeeb).
③ Tsis txhob muaj qhov cuam tshuam: Tsis txhob yuav "dyed bluestone slabs." Ntuj bluestone muaj cov xim ntuj hloov, thaum cov dyed slabs muaj cov xim tsis zoo uas zoo li tsis muaj tseeb, thiab lawv muaj feem cuam tshuam nrog lub hnub ci ntev.
