Customized Solutions and Best Practices for Txiav Marble Blocks rau hauv Slabs Siv Ultra-Thin Multi Wire Saw tshuab
Peb hom Marble txiav txoj kev
Marble blocks loj thiab hnyav. Cov ntsiab lus tseem ceeb rau kev txiav lawv rau hauv cov slabs yog "siab yield, tuab tuab, thiab tsis tshua muaj kev puas tsuaj." Qhov sib txawv tseem ceeb yog nyob rau hauv "brittleness," "kev ntxhib los mos qauv," thiab "cov ntsiab lus impurity." Cov txheej txheem txiav yuav tsum tau ua kom haum rau lub siab load thiab loj txiav ntim raws li qhov yuav tsum tau ua ntawm cov blocks slabs, yuav tsum tau tsom rau kev hloov kho rau lub pob zeb diamond hlau, txheej txheem, thiab cov txheej txheem pabcuam.
Cov kev daws teeb meem tshwj xeeb yog raws li hauv qab no:
1. High- lub teeb ci ntsa iab- xim marble blocks (xws li Calacatta, Snowflake White, Carrara Dawb)
Cov teeb meem tseem ceeb:
Tsis tshua muaj siab brittleness (lub zog flexural Tsawg dua lossis sib npaug li 8MPa), tsis sib xws kev ntxhov siab thoob plaws hauv qhov thaiv, yooj yim ua rau los ntawm -txiav npoo thiab kaum kab nrib pleb raws cov nplej thaum lub sij hawm txiav; lub teeb- xim slab nto yog khawb tau yooj yim los ntawm impurities nyob rau hauv lub block, thiab nruj gloss yuav tsum tau (Ntau tshaj los yog sib npaug rau 90GU) yuav tsum tau.
Txoj kev txiav rau slabs:
Pob zeb diamond hlau xaiv:0.5-0.6mm siab- lub zog electroplated pob zeb diamond hlau (abrasive particle loj 50-60 mesh, cov khoom siv hauv paus high-carbon steel hlau, tawg lub zog ntau dua lossis sib npaug li 2800MPa) raug xaiv kom ua tau raws li qhov siab nruj thiab siab load ntawm raw khoom slabs. Lub abrasive shedding tus nqi ntawm cov txheej electroplated yog tsawg dua los yog sib npaug li 8%, tsis txhob khawb ntawm qhov chaw slab.
Cov txheej txheem tsis (tsim rau daim ntawv thickness 30-80mm):
Kab ceev: 6-10m / s (tsawg-ceev, ruaj khov txiav kom txo tau qhov cuam tshuam ntawm hlau pom kev co ntawm cov khoom siv raw; kev co amplitude tswj Tsawg dua los yog sib npaug rau 0.02mm los xyuas kom meej cov ntawv flatness);
Pub ceev:Segmented tswj - theem pib (0-5mm): 0.1-0.2mm / min (qhib txiav kom tso tawm qhov kev ntxhov siab thiab tiv thaiv ntug chipping); Nruab nrab-theem (5mm - 80% ntawm raw khoom thickness): 0.4-0.6mm / min (ntsuas efficiency thiab daim ntawv zoo); Qhov kawg theem (tseem tshuav 20%): 0.2-0.3mm / min (tiv thaiv hauv qab ntug chipping thiab kaum tawg);
Kev tswj nruj:25-30N (tsim nyog rau raw khoom txiav load, tsis txhob muaj siab nro uas yuav ua rau sab hauv tawg ntawm daim ntawv kev ntxhib los mos, thaum ua kom cov pob zeb diamond hlau tsis plam thiab xyuas kom meej cov ntawv tuab).
Kev Tiv Thaiv Kev Pabcuam (Tsom ntsoov rau Kev Tiv Thaiv Cov Ntawv Ua tiav):
Txiav kua:Siv kev sib xyaw ua ke ntawm qis-kub dej-raws li kev txiav cov kua dej, tiv thaiv- tus neeg sawv cev dawb, thiab corrosion inhibitor (kub tsawg dua lossis sib npaug li 38 degree), siv los ntawm ntau- taw tes atomized txau (8-10 cov tshuaj tsuag nozzles, siab 0.6-0.8MPa, tee qhov loj me me, 10μ10-100m, qhov loj me thiab qhov loj me me) tshem tawm chips, tiv thaiv watermarks ntawm daim ntawv nto.
Raw Block Fixing:Kev siv lub tshuab nqus tsev vacuum adsorption, cov kab hluav taws xob nruj, thiab cov padding mos (10mm tuab polyurethane padding), nrog rau lub siab beam siab ntawm 0.3-0.5MPa, los tiv thaiv cov ntaub thaiv raw khoom thiab thickness sib txawv ntawm cov ntaub ntawv.
Kev tshem tawm nti:Lub nplhaib- zoo li qhov tsis zoo siab qhov chaw nres nkoj (tsis zoo siab -0.06MPa) + kev pom theem nrab (10μm precision) tshem tawm cov plua plav thiab gravel tam sim ntawd, tiv thaiv khawb ntawm daim ntawv nto.
2. Marble blocks uas muaj cov muaju tawv (xws li Jazz White, Carrara White, thiab Grey Vein Marble)
Cov teeb meem tseem ceeb:
Cov blocks muaj ntau cov quartz siv lead ua (Mohs hardness 7), ua rau muaj kev nce siab hauv zos txiav tsis kam ntawm ntau dua 30%. Qhov no yooj yim ua rau pob zeb diamond xaim dulling thiab tawg, thiab cov kev ntxhib los mos nyob ib ncig ntawm cov muaju yog qhov ua rau tawg, cuam tshuam rau kev ncaj ncees ntawm cov slabs. Qhov loj loj ntawm cov blocks kuj ua rau nws yooj yim rau thickness deviations tshwm sim thaum slab txiav vim hlau saw offset.
Slab txiav txoj kev:
Pob zeb diamond hlau xaiv: Siv 0.6-0.7mm resin-bonded pob zeb diamond hlau (abrasive particle loj 40-}50 mesh, muaj zog nws tus kheej-sharpening zog ntawm resin daim ntawv cog lus, ntau txheej kauv abrasive kev npaj, ceev 50% siab dua li cov hlau saws, kev txhim kho, txiav cov ntsiab lus ntawm kev ua haujlwm siab thiab kev ua haujlwm siab. xyuas kom tsis tu ncua slab txiav.
Cov txheej txheem tsis (tsim rau daim ntawv thicknesses ntawm 50-100mm):
Kab ceev: 8-12m / s (Ntau nrawm txo qis hauv zos compression ntawm abrasive los ntawm crystallization, ncua lub pob zeb diamond hlau lub neej thiab xyuas kom meej daim ntawv txiav);
Pub ceev: Txiav quab yuam kaw - voj tswj - teem caij quab yuam 30-35N. When the force exceeds 35N (contacting the densely crystallized area), the speed automatically decreases by 0.1-0.2mm/min (eg, from 0.5mm/min to 0.3mm/min). Kev nrawm dua ntxiv thaum lub zog qis dua 30N kom tsis txhob muaj ntau dhau ua rau daim ntawv chipping lossis xaim tawg;
Kev tswj nruj: 30-35N (Dynamic nyiaj them, 1.5N nro nyiaj them nyob rau hauv qhov chaw crystallized los tiv thaiv hlau pom sagging thiab xyuas kom meej ntawm daim ntawv txiav; thickness sib txawv tsawg dua los yog sib npaug rau ± 0.1mm).
Auxiliary Protection (Tsom rau Slab Precision thiab Kev Ncaj Ncees):
Txiav kua: Ntxiv "hnyav siab tiv thaiv-tus neeg sawv cev hnav" (xws li phosphate ester) kom txo cov kev sib txhuam coefficient ntawm cov muaju thiab pob zeb diamond hlau (txo txiav tsis kam los ntawm 20%), thiab nce tus nqi ntws mus rau 30-40L / min (txhim kho nti tshem tawm, tiv thaiv cov hmoov av siv lead ua kom tsis txhob khawb qhov abrasive);
Cov khoom siv Calibration: Ua ntej txiav, siv lub laser positioning ntsuas los ntsuas qhov sib luag ntawm cov kev taw qhia lub log sib dhos (yuam qhov tsawg dua lossis sib npaug li 0.015mm / m), thiab siv qib los ntsuas qhov kev tso kawm ntawm cov khoom nyoos ( kab rov tav yuam kev tsawg dua lossis sib npaug ntawm 0.1mm / m ).
3. Loose-textured marble blocks (xws li beige marble, golden beige marble, lub teeb xim av mesh marble)
Core Pain Points:
Cov qauv xoob ntawm cov pob zeb nyoos (porosity Ntau dua lossis sib npaug li 3%) yooj yim ua rau loj - thaj tsam kev ntxhib los mos thiab chipping thaum txiav rau hauv cov nplais, ua rau cov nplais seem; qhov loj ntawm cov kua dej nqus ntawm cov blocks nyoos yooj yim ua rau cov xim sib txawv ntawm cov slabs vim yog txiav cov kua dej nkag; qhov chaw txiav yog nquag fuzzing, cuam tshuam rau gloss ntawm cov slabs hauv kev ua haujlwm tom ntej.
Slab Cutting Method:
Pob zeb diamond hlau xaiv: 0.55-0.6mm electroplated pob zeb diamond hlau (abrasive particle loj 50-60 mesh, cov khoom tsis zoo, npib tsib xee plating rau kev txhim kho rigidity, tensile lub zog ntau dua los yog sib npaug rau 2600MPa) yog siv los txo tearing ntawm cov nplej xoob, hloov mus rau qhov chaw vibration ntawm cov ntaub ntawv raw khoom, thiab xyuas kom meej cov ntaub ntawv raw khoom.
Cov Txheej Txheem Txheej Txheem (Siv rau daim ntawv tuab 40-90mm):
Hlau Ceev: 10-14m / s (High-speed txiav shortens lub sij hawm sib cuag ntawm cov pob zeb diamond hlau thiab xoob nplej, txo cov qoob loo thiab chipping);
Pub Ceev: 0.5-0.7mm / min (Ntev pub kom tsis txhob muaj kev ntxhov siab tsis sib xws ntawm cov nplej hauv zos los ntawm kev hloov pauv ceev);
Kev Tswjhwm nruj: 32-36N (Kev nruj siab tso cai rau lub pob zeb diamond xaim "ceev txiav los ntawm" cov khoom siv raw, txo cov nplej txhuam thiab ua kom tawg, thaum ua kom ruaj khov hlau pom kev ua haujlwm thiab daim ntawv flatness).
Kev Tiv Thaiv Kev Pabcuam (Tsom ntsoov rau kev ntxhib los mos thiab xim sib txawv tiv thaiv):
Txiav kua: Ntxiv "waterproof sealant" (xws li tus neeg sawv cev silane coupling) kom txo tau cov kua nqus dej thiab xim sib txawv ntawm qhov chaw slab; siv "tsawg-siab loj- thaj tsam txau" (siab 0.4-0.6MPa, tshuaj tsuag thaj tsam ntau dua lossis sib npaug li 0.8m²) kom tsis txhob muaj kev kub ntxhov tawg tawg thiab ua rau cov slabs poob;
Slab Post-kev kho mob: Tam sim ntawd tom qab txiav rau hauv slabs, tshuaj tsuag tag nrho saum npoo nrog "raws li cov khoom siv- tshwj xeeb sealant" (hloov cov xim pob zeb) txhawm rau txhawm rau lub qhov hws thiab tiv thaiv kom tsis txhob muaj kev ntxhib los mos ntxiv thaum lub sij hawm thauj mus los thiab ua tiav, thaum tseem txhim kho qhov gloss ntawm qhov chaw txiav (gloss nce los ntawm 5-8U).
