Marble slab yuav los ntawm Tuam Tshoj marble slab Hoobkas feem ntau yog qhov tsis xws luag - tswj kev tawm dag zog, tsis yog txheej txheem kev xaiv pom. Cov neeg yuav khoom ntsuas kev ncaj ncees los ntawm cov khoom ruaj khov zoo, mesh rov qab zoo li qub, thiab kev ua haujlwm ntog sib xws thoob plaws cov kab laib thiab cov tshuab polishing. Cov kev lees paub tseem ceeb feem ntau suav nrog kev nqus dej<0.40%, flexural strength >10-12 MPa, thiab thickness kam rau ua nyob rau hauv ± 1 hli.
1. Khoom siv hauv paus: Marble Slab tso tawm los ntawm Tuam Tshoj ntau lawm Systems
Kev lag luam marble slabs pib los ntawm block extraction nyob rau hauv cov chaw txua txiag zeb, ua raws li cov thawj txiav nyob rau hauv blocks yards thiab theem nrab tiav ntawm laib saws los yog multi- hniav infrared cutters.
Cov txiaj ntsig tseem ceeb ntawm lub cev siv hauv kev muab qhab nia export:
| Khoom | Standard Range (Export Qib) | Test Reference |
|---|---|---|
| Compressive zog | 80-140 MPa | ASTM C 170 Cov |
| Flexural zog | 8-14 MPa | TS EN 12372 |
| Kev nqus dej | 0.20%–0.45% | ASTM C 97 Cov |

Marble xaiv nyob rau theem no txiav txim downstream yield thaum lub sij hawm CNC dej - dav hlau txiav thiab slab nesting optimization rau countertop los yog façade fabrication.
2. Kev soj ntsuam lub moj khaum: Mesh Backing, Resin Filling, thiab cov qauv txuas ntxiv
Ntawm slab txoj kab tawm, kev tshuaj xyuas yog ua tiav ntawm qhov qhuav -ntev tshuaj ntsuam lub platform nyob rau hauv kev tswj teeb pom kev zoo (5000–6500K). Kev ntsuam xyuas tsom mus rau kev txhim kho kev tsim kho thiab kev pom kev txuas ntxiv.
Mesh Backing (Fiber Reinforcement Layer)
Siv rau slabs nrog tej yam ntuj tso fissure zones
Polyester lossis fiberglass mesh txuas nrog epoxy resin
Target adhesion strength: >1.5 MPa tev tsis kam
Tiv thaiv kev nthuav tawm cov kab nrib pleb thaum thauj kev vibration
Resin Filling System
Nqus -pab epoxy txhaj rau hauv micro- tawg
Xim-match resin siv rau dawb, grey, thiab beige marble pawg
Ncej - kho hardness: Ntug D > 80
Reject threshold: open crack width >2 hli los yog tsis ruaj khov
Phau ntawv-Matching Control (Vein Continuity)
Slabs ua ke ua ke los ntawm cov neeg laib pom cov khoom tso tawm
Maximum vein offset kam rau ua: Tsawg dua los yog sib npaug li 3 hli tshaj 2.4 m ntev
Orientation marking siv thaum lub sij hawm slab flipping theem
3. Surface Finishing Engineering: Gang Saw Output thiab Polishing Line Stability
Marble slab nto kev ua tau zoo yog txiav txim siab los ntawm ob lub tshuab ua ntu zus: laib pom txiav precision thiab automated polishing calibration.
Gang Saw Cutting System
Hniav suav: 80-120 steel hniav ib thav duab
Txiav voj voog stability: ± 0.5 hli slab thickness variation
Pub tus nqi tswj: 25-40 cm / teev nyob ntawm hardness index
Cov zis nto roughness (Ra): 12-18 μm ua ntej polishing
Automated Polishing Kab
Ntau - lub taub hau abrasive system (txog 16 lub taub hau ib kab)
Grit kev nce qib: 50 → 1200 → 3000 resin pads
Final gloss level: >90℃gloss meter nyeem ntawv rau qib hwm slabs
Kev lim dej tsis zoo: ntug nti nrhiav pom ntawm qhov muag pom qhov muag array
Nto uniformity ncaj qha cuam tshuam fabrication yield thaum lub sij hawm CNC dej - dav hlau txiav rau kev lag luam flooring layouts thiab countertop templating.

4. Xim Stability, Quarry Variation, thiab ntau lawm sorting logic
Marble yog lub pob zeb metamorphic nrog cov pob zeb hauv av sib txawv. Factory- theem tswj tsom rau batch segregation es tsis yog homogenization cuav.
Sorting Parameters:
Calcite crystal density variation index
Kev faib tawm ntawm cov leeg (linear vs chaotic)
Hlau oxide concentration zones ( cuam tshuam rau yellowing txaus ntshai)
Nto polish reflectivity variance (<5% deviation allowed per batch)
Kev sib xyaw xim yog ua tiav nyob rau hauv cov yards ua ntej slab txiav kom ntseeg tau tias cov dej ntws sib xws hauv façade lossis flooring tej yaam num.
5. Logistics Engineering: Crating, Load Control, thiab Seaworthy Protection
Export stability nyob ntawm txhua yam kev tiv thaiv kab mob thaum lub caij hla dej hiav txwv.
Seaworthy Ntoo Crates System
Thaum tshav kub kub- kho hardwood ncej (ISPM 15 raws)
Internal ua npuas ncauj + roj hmab cais txheej

FAQ (Engineering & Procurement Focus)
1. Dab tsi thickness yog tus qauv rau export marble slabs los ntawm Tuam Tshoj?
Feem ntau export slabs yog calibrated ntawm 18 hli los yog 20 hli. Thickness kam rau ua yog feem ntau tswj nyob rau hauv ± 1 mm nyob ntawm seb cov laib pom calibration thiab polishing kab stability.
2. Marble slabs puas tuaj yeem txhawb nqa phau ntawv- sib piv rau cov phab ntsa loj?
Yog lawm. Phau ntawv- kev sib piv yog raug tua nyob rau hauv pawg neeg pom sequencing theem. Slabs yog ua ke ua ke nrog cov leeg offset kam rau ua tswj tsis pub dhau 3 hli ib 2.4 m slab ntev.
3. Dab tsi yog qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis rau cov thawv xa khoom?
Standard MOQ yog ib lub thawv 20ft, feem ntau 400-600 m² nyob ntawm slab thickness thiab crate configuration. Mixed xim loading yog ua tau nrog ua ntej sorting txoj kev npaj.
