Lub slate ntawm lub rooj billiard yog cov khoom tseem ceeb cuam tshuam rau kev txhaj tshuaj raug thiab pob trajectory stability. Nws cov khoom siv thiab kev siv tshuab ncaj qha txiav txim siab qhov flatness thiab lifespan ntawm lub rooj saum npoo. Tam sim no, cov ntaub ntawv tseem ceeb xws li bluestone, marble, thiab granite. Cov khoom sib txawv muaj cov yam ntxwv sib txawv. Cov hauv qab no yog cov ncauj lus kom ntxaws sib piv:
Bluestone (tsuas yog limestone)
Bluestone yog cov khoom siv slate tshaj plaws thiab siv dav rau cov rooj billiard, tshwj xeeb tshaj yog thawj qhov kev xaiv rau kev sib tw kev tshaj lij thiab siab - cov rooj zaum kawg. Nws cov ntsiab lus tseem ceeb yog calcium carbonate, nrog rau nruab nrab hardness (Mohs hardness 3-4).
Zoo heev flatness: Nws cov qauv ntuj yog ntom thiab nws cov crystals zoo. Tom qab polishing precision, qhov kev ua yuam kev flatness tuaj yeem tswj tau nyob rau hauv 0.1 hli, ua kom ruaj khov rolling trajectories rau lub pob cue thiab cov khoom pob, zam "dhia" thiab "tawm- taug qab" teeb meem tshwm sim los ntawm qhov chaw tsis sib xws.
Kev poob siab zoo: Nws muaj qee qhov elasticity, uas tuaj yeem cuam tshuam qhov cuam tshuam ntawm lub pob thiab lub rooj saum npoo, txo cov pob cue "bouncing" thiab txo suab nrov thaum txhaj tshuaj.
Kev ruaj ntseg siab: Tsis muaj kev cuam tshuam los ntawm qhov kub thiab av noo hloov pauv, nrog qhov sib txawv ntawm cov thermal expansion thiab contraction, nws tsis yooj yim deformed ntev - siv sij hawm (tshwj xeeb tshaj yog hnub nyoog bluestone kho nrog "kev laus kho," uas muaj kev ruaj ntseg zoo dua).
High Adaptability: Nws lub ntsej muag zoo nkauj zoo nkauj tso cai rau kev sib raug zoo nrog cov ntaub pua rooj, txo qis los yog wrinkling thiab ncua nws txoj sia.
Marble (sawv cev los ntawm "Yun Shi") Marble yog ib lub pob zeb metamorphic pom nyob rau hauv lub ntiaj teb crust, feem ntau muaj xws li calcium carbonate thiab magnesium carbonate. Nws los ntawm ntau yam xim (xws li dawb, dub, thiab grey nrog cov qauv) thiab muaj Mohs hardness ntawm 3-3.5, me ntsis qis dua bluestone.
Qhov zoo:
Kev zoo nkauj zoo nkauj: Cov khoom siv ntuj tsim tshwj xeeb ua rau nws muaj kev xaiv tsim nyog rau "cov rooj zoo nkauj billiard," zoo tagnrho rau cov tsev neeg nrhiav kev sib koom ua ke hauv tsev (xws li villas lossis club lounge).
Tus Nqi Nruab Nrab: Ntau dua li bluestone, nrog kev ua haujlwm yooj yim, nws yog pheej yig dua li siab -bluestone zoo, tsim nyog rau cov peev nyiaj- cov neeg siv paub zoo uas tseem ceeb rau kev zoo nkauj (feem ntau hauv tsev billiard rooj nqi ntawm 8,000-15,000 yuan). Ib qho yooj yim rau polish: Qhov saum npoo yog qhov yooj yim rau kev ua kom tiav, thiab pib flatness tau txais.
Granite
Granite yog pob zeb tsis muaj zog, feem ntau yog tsim los ntawm quartz thiab feldspar, nrog Mohs hardness ntawm 6-7, ua rau nws nyuaj tshaj plaws ntawm peb cov ntaub ntawv.
Qhov zoo: Siab hardness thiab muaj zog hnav tsis kam: Qhov saum npoo muaj kev khawb zoo heev; Txawm hais tias ntaus golf los yog cov khoom nyuaj, nws tsis yooj yim cim, ua rau lub neej ua haujlwm ntev (tshwj xeeb yog haum rau siab - siv zaus hauv pej xeem qhov chaw).
High density and heavy texture: The density is approximately 2.8-3.0 g/cm³, with a hard structure, and the flatness is relatively stable in the short term (1-3 years).
