Hauv kev lag luamsandblasting rau xeb tshem tawmlos ntawm steel, xaiv txoj cai abrasive - txhais los ntawmmesh lojthiabkev huv - ncaj qha cuam tshuam rau ob qho tib sicov ntaub ntawv tshem tawm tus nqithiabresulting nto profile. Ib qho kev sib piv yog88 mesh (88% SiC)piv100 mesh (90% SiC). Txawm hais tias lawv tshwm nyob ze ntawm tus lej, tuscoarser/finer balancethiabpurity sib txawvhloov li cas lawv ua raws liceevthiabua kom zoo.
NtawmZhenAn, nrog30 xyoo ntawm kev paubMuab SiC rau abrasive blasting, peb txheeb xyuas qhov kev xaiv tshem tawm xeb sai dua ntawm cov hlau thiab yuav ua li cas txhua qhov cuam tshuam rau qhov chaw tiav.
1. Sandblasting xeb tshem tawm: Cov txheej txheem tseem ceeb
Sandblasting tshem tawm xeb thiab zeb nplai los ntawmmicro- txiav, tawg, thiab kinetic cuam tshuam:
Particle lojtswj qhov tob ntawm kev txiav ib feem thiab tus nqi ntawm cov khoom tshem tawm ib lub sij hawm.
Puritycuam tshuam rau kev hnav tsis kam ntawm cov abrasive (ntev ntev hauv kev rov ua dua tshiab) thiab qhov kev pheej hmoo ntawm cov kab mob ntawm cov khoom tsis huv.
Hardness & sharpnessntawm SiC xyuas kom nruj tshem tawm txawm nyob rau ntawm cov oxides nyuaj.
Lub hom phiaj yuav yogceev tshaj plaws(piv txwv li, hnyav xeb ntawm cov qauv hlau) lossistswj tiav(piv txwv li, ua ntej- txheej txheej prep).
2. Mesh Loj: 88 vs . 100 - Coarser lossis Finer?
Mesh naj npawb=qhib rau ib kab inch;qis tus lej=loj dua.
88 mesh≈ 180 µm particles -coarser
100 mesh≈ 150 µm particles -zoo dua
Kev cuam tshuam rau tus nqi tshem tawm:
Coarser (88 mesh): Loj loj thiab thaj chaw tiv tauj → tshem tawm xeb sai dua hauv ib qho dhau los; zoo dua rau tuab, hnyav xeb.
Qhov loj me (100 mesh): Cov khoom me me → txo cov khoom tshem tawm ib qho cuam tshuam → qeeb xeb tshem tawm, tab sis kev tswj xyuas ntau dua.
Yog li ntawd rauceev ceev, 88 meshmuaj qhov zoo.
3. Purity: 88% vs . 90% SiC - Hnav & Qhov cuam tshuam
88 mesh (88% SiC): Cov ntsiab lus impurity siab dua (~ 12% SiO₂, dawb C, hlau oxides) → kev tawg sai dua hauv kev rov ua dua tshiab, tuaj yeem ua rau muaj kab mob.
100 mesh (90% SiC): Cov ntsiab lus qis dua impurity (~ 10%) → kev txiav ntau dua, lub neej ntev dua, huv si nrog cov khoom seem tsawg dua.
Kev cuam tshuam rau saum npoo tiav:
88% SIB: Cov impurities tuaj yeem ua rau cov pob txha tsis sib xws thiab qee zaus cov qhov tob tob; tuaj yeem tso cov kab silica residue cuam tshuam rau txheej adhesion.
90% SiC: Kev txiav cov tshuaj ntxuav tu, ntau qhov sib xws ntawm qhov profile, zoo dua rau cov ntawv thov uas yuav tsum tau ua kom zoo ib yam Ra thiab qhov paug tsawg.

88 mesh (88% SiC)tshem tawm xebsai dua vim qhov loj me me - zoo tagnrho rau hnyav xeb tshem tawm qhov twg ceev trumps tiav.
100 mesh (90% SiC)yield afiner, huv si nto nrog kev sib kis tsawg dua - zoo dua rau ua ntej- txheej lossis cov hlau ua haujlwm zoo.
5. Cov txheej txheem xaiv tswv yim
Heavy Rust / Thick Mill Scale→ Xaiv88 mesh (88% SiC)rau qhov siab tshaj plaws tshem tawm.
Lub Teeb Rust / Final Surface Prep→ Xaiv100 mesh (90% SiC)rau kev tswj kom tiav thiab tsis muaj paug.
Recycling Systems→ 100 mesh (90% SiC) kav ntev dua thiab ua kom zoo ib yam ntawm ntau lub voj voog.
Txheej Adhesion Critical→ Ntau dua purity (90% SiC) txo qhov kev pheej hmoo ntawm cov ciam teb tsis muaj zog los ntawm impurity residues.
Nqi vs. Lifecycle→ 88 mesh yuav pheej yig dua ib kg tab sis hnav sai dua; 100 mesh yuav txo tau tag nrho cov abrasive noj nyob rau hauv reusable systems.
6. Kev lag luam piv txwv
Ib tus neeg ua haujlwm steel ua haujlwm ua haujlwm ntawm kev txhim kho choj:
Siv88 mesh (88% SiC)rau thawj zaug hnyav xeb tshem tawm ntawm lub ntsiab girders → ceev Tshuag tshem tawm.
Hloov mus rau100 mesh (90% SiC)rau qhov kawg dhau ntawm kev sib txuas daim hlau thiab welds → xyuas kom zoo ib yam profile thiab huv si nto rau xim adhesion.
Qhov tshwm sim: Txo rework, ua tau raws li txheej spec nrog tsawg dua abrasive hloov.
