XaivWalnut Plhaub SandblastingMedia: Tsom ntsoov rau Grit Loj, Hardness, thiab Zoo li
Walnut plhaub sandblasting xov xwm yog dav siv nyob rau hauv qhuav tumbling vim hais tias ntawm nws nruab nrab hardness thiab zoo toughness. Nws tuaj yeem pab tshem tawm cov teeb meem me me yam tsis tau khawb lub workpiece thaum xaiv qib raug. Lub abrasive yuav tsum tau sib phim rau qhov loj me thiab qhov yuav tsum tau ua kom tiav kom tsis txhob siv cov khoom uas ntxhib dhau, uas yuav ua rau khawb, lossis zoo heev, uas yuav txo tau kev ua haujlwm.
1. Xaiv Raws Li Grit Loj (Particle Loj)
Grit loj yog ntsuas hauv mesh. Qhov siab dua tus lej mesh, qhov zoo dua cov khoom. Qib tsim nyog nyob ntawm qhov pib ntawm qhov chaw ntawm lub workpiece thiab qhov xav tau.

2. Xaiv Raws li Hardness: Npaj rau 2.5–3.0 ntawm Mohs Scale
Lub hardness ntawm abrasive yuav tsum tsim nyog rau cov khoom siv ua haujlwm kom txo tau qhov kev pheej hmoo ntawm khawb.
Rau cov ntaub ntawv softer: Rau txhuas, yas, thiab lwm yam ntaub ntawv uas muaj ib tug hardness hauv qab no kwv yees li 2.5 Mohs, xaiv softer walnut plhaub sandblasting xov xwm nrog ib tug hardness nyob ib ncig ntawm 2.5 Mohs. Tsis kho walnut shells yuav tsim nyog, nyob ntawm seb lawv tus mob thiab qib.
Rau cov ntaub ntawv nyuaj: Rau steel, ceramics, thiab lwm yam ntaub ntawv uas muaj ib tug hardness saum toj no 5 Mohs, xaiv harder walnut plhaub xov xwm nrog ib tug hardness ze rau 3.0 Mohs, xws li degreased thiab qhuav plhaub, kom muaj kev txiav txim zoo thiab txhim kho kev ua tau zoo.
Ib qho yooj yim hardness check: Softer shells yuav zom nyob rau hauv lub teeb siab, thaum lub plhaub tawv yuav tsum tau ntau zog los ua txhaum. Qhov no tsuas yog ib txoj kev tshuaj ntsuam ntxhib xwb; kev tsim khoom zoo ib yam yuav tsum muaj cov khoom tsim nyog thiab kev sim.
3. Xaiv raws li Particle Shape: Irregular Granules nyiam dua
Cov duab ntawm walnut plhaub hais txog lawv qhov chaw sib cuag nrog lub workpiece thiab qhov sib xws ntawm cov khoom tshem tawm.
Pom zoo: Irregularly crushed hais nrog ntuj npoo uas tsis dhau ntse. Lawv muab kev sib cuag zoo dua nrog cov khoom ua haujlwm thiab tuaj yeem xa cov txiaj ntsig deburring thiab polishing.
Siv ceev faj: Cov kab sib npaug los yog kheej kheej feem ntau muaj kev txiav txim siab tsawg dua. Tej zaum lawv yuav tsim nyog rau kev ua tiav zoo tab sis tuaj yeem ua tsis tau zoo rau cov ntawv thov uas yuav tsum tau tshem tawm burr tseem ceeb.
4. Lwm yam kev qhia tseem ceeb
Cov ntsiab lus impurity: Khaws cov impurities, xws li plua plav thiab hmoov zoo plhaub, qis dua 3% yog tias ua tau. Cov kab mob ntau dhau tuaj yeem sau rau ntawm qhov chaw ua haujlwm thiab tawm cov cim tsaus. Kev tshuaj xyuas cov xov xwm nrog lub sieve sib haum rau qhov xav tau mesh loj ua ntej siv tuaj yeem pab tshem tawm cov nplua nplua thiab cov khoom loj.
Cov ntsiab lus noo noo: Cov ntsiab lus noo noo qis dua 5% yog pom zoo. Cov dej noo ntau dhau tuaj yeem ua rau cov xov xwm clump, ua rau tsis sib xws. Thaum cov khoom siv hlau thiab cov khoom siv sib xyaw ua ke, kev tswj tsis zoo ntawm cov dej noo kuj tseem tuaj yeem ua rau kev txhim kho corrosion lossis microbial loj hlob hauv cov txheej txheem sib tov.
Degreasing: Rau qhov tseeb lossis kev sib kis- cov khoom tseem ceeb, xws li cov khoom siv hluav taws xob, xaiv degreased walnut plhaub xov xwm kom txo cov roj seem ntawm cov khoom ua haujlwm. Rau kev siv dav dav - lub hom phiaj, cov xov xwm tsis kho yuav yog qhov kev xaiv pheej yig dua yog tias nws cov ntsiab lus roj tsis cuam tshuam rau cov txheej txheem.
Common Pitfalls: Peb Qhov Tseem Ceeb Ceev faj
1. Ua ib qho me me -Batch sim ua ntej
Ua ntej pib tag nrho - teev ntau lawm, sim kwv yees li 1-2 kg ntawm walnut plhaub sandblasting xov xwm nrog 50-100 mL ntawm tumbling compound thiab peb mus rau tsib workpieces. Khiav qhov kev ntsuam xyuas rau 10-30 feeb, tom qab ntawd tshuaj xyuas qhov chaw rau khawb thiab xyuas seb qhov xav tau gloss puas tau tiav.
Kho qhov mesh loj, qhov sib xyaw ua ke, thiab lub sijhawm ua haujlwm raws li cov txiaj ntsig ua ntej tsiv mus rau batch ntau lawm.
2. Tswj tus nqi ntawm Tumbling Compound
Raws li qhov pib taw tes, siv kwv yees li 1% -3% tumbling compound los ntawm qhov hnyav ntawm walnut plhaub tawm. Piv txwv li, 100 kg ntawm xov xwm yuav xav tau ib ncig ntawm 1-3 kg ntawm compound.
Kev sib xyaw ntau dhau tuaj yeem ua rau cov xov xwm sib txuas ua ke, txo qis kev sib cuag nrog cov khoom ua haujlwm thiab ua rau cov txiav txiav tsis muaj zog. Tsawg dhau tuaj yeem ua rau muaj kev sib txhuam qhuav, ua rau khawb thiab hnav tawm sai dua.
Tus nqi tsim nyog nyob ntawm qhov sib xyaw ua ke, cov khoom siv ua haujlwm, thiab cov khoom siv, yog li paub meej tias qhov ntau npaum li cas los ntawm kev sim.
3. Rov qab siv Walnut Plhaub Media kom raug
Siab - zoo walnut plhaub sandblasting xov xwm tuaj yeem rov qab siv peb mus rau tsib zaug, nyob ntawm seb cov khoom siv ua haujlwm, qib paug, thiab kev ua haujlwm. Ntxiv kwv yees li 5% -10% cov xov xwm tshiab rau ib lub voj voog raws li xav tau los them rau qhov poob thiab tswj kev ua haujlwm zoo ib yam.
Yog tias cov khoom ua haujlwm muaj roj lossis roj, ntxuav cov xov xwm ua ntej rov siv dua thiab ziab kom huv si nrog cua sov. Qhov no yuav pab tiv thaiv kom tsis txhob muaj kab mob sib kis thiab cuam tshuam rau cov khoom tom ntej.
Summary: Ib kauj ruam - los ntawm - Cov txheej txheem xaiv
Txhais cov kev xav tau: Txheeb xyuas cov khoom siv ua haujlwm (hlau lossis tsis yog{0}}hlau), lub hom phiaj ua haujlwm (deburring, polishing, lossis deg npaj), qhov luaj li cas ntawm qhov chaw ua haujlwm, thiab thawj qhov chaw roughness.
Xaiv cov walnut plhaub tawm: Xaiv cov theem ua thiab mesh loj ua ntej, ces xyuas qhov hardness thiab particle zoo. Ua ntej cov khoom tsis zoo nrog cov qib impurity tsawg thiab hardness haum rau lub workpiece.
Kuaj thiab ua kom zoo: Khiav ib qho me me -batch sim, kho cov txheej txheem tsis, thiab tom qab ntawd mus rau tag nrho - nplai ntau lawm.
Los ntawm kev ua raws li cov kauj ruam no, cov tuam txhab tsim khoom tuaj yeem ua tiav kev ua haujlwm qhuav tumbling nrog kev pheej hmoo ntawm kev puas tsuaj rau saum npoo thiab tswj tau zoo dua cov nqi khiav lag luam. Xaiv txoj cai walnut plhaub sandblasting xov xwm yuav pab txo qis qhov tsis tsim nyog rov ua haujlwm, tiv thaiv kev tsis lees paub ntawm qhov chaw ua haujlwm, thiab tswj xyuas kom zoo ib yam.
