Dej khov qhuav blastingThev naus laus zis yog ib qho kev lag luam tu tau zoo uas muaj cov tsis muaj abrasive, eco-phooj ywg hloov kho rau cov kev coj ua ib txwm muajSandblasting los yog tshuaj lom neeg tu {. Lub hauv paus ntsiab lus ntawm cov dej khov qhuav yog qhov yooj yim: nws cabagages qhov kub thiab txias thiab kub sai saidej khov nab kuabHais kom tshem tawm cov tawv ncauj paug .}}}} Tab sis vim li cas particle loj me ntsis thiaj li? Nws cuam tshuam li cas tu kev tu ua ua haujlwm, ua tau zoo, thiab kev nyab xeeb? Cov lus sau no rho tawm rau hauv lub nuances ntawm cov khoom siv dej khov me me, thiab muab cov lus qhia tseem ceeb rau cov neeg siv khoom siv, thiab muab kev ua haujlwm zoo {}}
Vim li cas cov teeb meem loj me me hauv cov dej khov qhuav
Dej khov kho dej khov rau cov pa roj carbon dioxide (co) Cov khoom noj qhuav me me cuam tshuam rau kev ua tiav, "cov lus teb nyob rau hauv kev nkag siab qhov loj me me, koj tuaj yeem txhim kho cov khoom siv kom huv, thiab txawm tias txo cov nqi kev ua haujlwm {}}
Cov tub ntxhais tseem ceeb ntawm cov dej khov qhuav
Txhawm rau kom nkag siab qhov cuam tshuam ntawm qhov loj me me, cia thawj zaug tshawb peb lub tsev kawm qib thawj tsav tsheb qhuav txias:
- Kev cuam tshuam kev cuam tshuam: Cov dej khov qhuav, tau tawm ntawm cov kev ua haujlwm nrawm, tsis zoo li cov neeg kho tshuab, tsis muaj kev cuam tshuam lossis tsis muaj qab hau .
- Thermal poob siab: ntawm -78.5 degree, ua rau cov dej khov kom qhuav sai sai, ua rau lawv loj tuaj tshem tawm thiab yooj yim dua.
- Sublimation tawg ntho: thaum cuam tshuam, qhuav cov lus qhia tam sim ntawd hloov mus rau roj av {} Lub pob tw me me no tawm ntawm qhov chaw tsis huv.
Qhov loj me me cuam tshuam rau kev sib npaug thiab kev siv cov txheej txheem ntawm cov txheej txheem no, sau cov txiaj ntsig tu cov txiaj ntsig uas yuav tsum ua tib zoo xav txog {}}
Cov dej khov kom qhuav: Kev Ua Haujlwm thiab Cov yam ntxwv
Cov dej khov qhuav feem ntau feem ntau ntawm 0 {{{{}} 05mm mus rau 10mm, txhua qhov haum rau cov ntawv thov tshwj xeeb. Ntawm no yog kev tawg ntawm cov pawg tseem ceeb:
- Cov khoom me me (0 {. 05-3mm): zoo li cov khoom siv hluav taws xob kom zoo nkauj {}} Txawm li cas los xij, lawv qis dua kev txhawb nqa lub zog kev lim hiam ua hauj lwm zoo rau tuab, cov khoom siv tawv ntoo.
- Nruab nrab teev (3-5mm): cov txheej txheem pelaste loj heev tab sis siv ntau yam kev ua tau zoo, suav nrog cov roj uas tsis muaj zog, nrog rau cov roj ntsha ua kom muaj zog me me lossis cov carbon monoxide)
- Cov khoom loj (5-10mm): chunky thiab muaj zog rau cov steel lossis cov roj hmab uas muaj kev puas tsuaj ceev ceev rau cov ntaub ntawv so ceev ceev rau cov ntaub softer .
Nkag siab cov yam ntxwv no yog thawj kauj ruam mus rau tailoring particle loj rau koj cov kev ntxuav tu tshwj xeeb .
Yuav ua li cas particle loj cuam tshuam rau cov txiaj ntsig
The choice of particle size impacts several critical aspects of dry ice blasting. Let's explore how:
1.}}} Kev ntxuav tawm
Cov khoom loj dua (5-10 hli) xa cov khoom siv roj hmab ntau dua, ua rau cov pa roj hmab ntau dua, cov khoom siv me me (0}} 05-33mm) excel nyob rau hauv precision Cov haujlwm, ua tau zoo tshem tawm cov yeeb yaj kiab nyias lossis cov ntawv me me ntawm cov chaw sib txawv, xws li Circuit Court Cam lossis Pwm.
2.}}} Tu cov meej
Cov khoom me dua kev ua kom qis dua thiab cov khoom siv ua kom zoo nkauj, qhib cov chaw ua kom zoo nkauj, qhib cov chaw ua kom huv si, qhib cov khoom noj khoom haus kom meej yog tsawg dua txog qhov tseeb thiab ntxiv txog Brute Force .
3.} substrate kev nyab xeeb
Kev tiv thaiv lub hauv qab saum npoo yog qhov tseem ceeb hauv ntau cov ntawv thov zoo li cov hlau, muaj kev nyab xeeb rau cov khoom sib xyaw ua ke, yog qhov ua tau zoo ntawm Genterved .
4.}} Cov dej khov qhuav thiab muaj txiaj ntsig
Cov khoom loj dua feem ntau xav tau cov dej khov ntau dua vim lawv cov kev siv hluav taws xob siab, ua rau lawv muaj kev pheej hmoo me ntsis txawm hais tias nws yuav raug teeb meem sai sai
Cov xwm txheej no yog vim li cas qhov loj me me tsis yog ib qho loj-haum-txhua qhov kev txiav txim siab kom loj rau koj qhov kev sib tw tu kom loj rau kev ua tau zoo {}}
Xaiv txoj cai txoj cai loj rau koj daim ntawv thov
Xaiv cov kev xaiv qhov loj me tshwm sim nyob ntawm cov hom paug, cov khoom siv substrate, thiab cov khoom siv tu} Tam sim no yog cov qauv qhia tswv yim:
- Precision tu (e {.}}}}} Lawv cov khoom siv khoom noj kom huv si kom huv si yam tsis muaj kev ua kom huv.
- Kev tu siab dav (e {. g}}}}}}
- Hnyav-Luag Tu (E {{1} gase, tuab}, cov roj ntsha (5)
Piv txwv li, cov khoom noj ua khoom noj tsis huv stainless hlau tuaj yeem tshem tawm cov txheej txheem hluav taws xob tuaj yeem tau txais txiaj ntsig los ntawm 5mm pellots rau sai dua kev tshwm sim {}}
Qhia peb cov PCBA Qhuav Khov Tshuab
Qhov no qhuav lub cav qhuav nta ib qho kev tsim qauv hluav taws xob, ua rau nws ruaj khov thiab siv cov khoom siv hluav taws xob tsis sib xws nrog cov txheej txheem hauv hluav taws xob xws li nthwv dej Soldering . Raws li cov neeg siv dej num, cov dej khov nab kuab, cov dej khov nab kuab tuaj yeem yog 05-0- hli lossis 0.2-0.6 hli.
Synerozing particle loj nrog cov khoom tsis muaj
Qhov loj me me tsis ua haujlwm cais-nws yuav tsum tau ua khub nrog cov khoom siv tau zoo los qhib nws cov peev txheej tag nrho:
- Tawg siab: cov khoom me me tuaj yeem rub tawm cov kev ntsuas siab dua kom them nyiaj rau qis dua kev txhawb nqa kom tiv thaiv kev ua kom muaj zog.
- Nozzle tsim: Nozzles cuam tshuam rau particle thiab faib {{{{lazing {partanzles txhim kho loj-particle cuam tshuam ....
- Blast nrug thiab kaum: Ua kom muaj qhov zoo tshaj plaws ntawm cov cua sov sov, thaum muaj kev ncua ntev mus txog siab ntev tshaj {}}
- Pub tus nqi thiab cua-rau-dej khov piv txwv: Kev ntxuav cov khoom siv tsis sib xws
Los ntawm kev nplua-tu cov tsis sib xws, koj tuaj yeem ua kom pom tseeb qhov ua tau zoo ntawm koj xaiv cov particle thiab ua tiav cov txiaj ntsig zoo {}}
Kev txiav txim siab kev nyab xeeb rau kev sib txawv ntau thiab tsawg
Qhuav dej khov kho yog inherently muaj kev nyab xeeb dua cov txheej txheem abrasas, tab sis particle loj qhia txog kev txiav txim siab muaj kev nyab xeeb:
- Cov khoom loj me: lawv cov kev cuam tshuam zoo heev tuaj yeem ua rau muaj kev tiv thaiv kev tiv thaiv, nrog rau kev deb ntawm thaj chaw ua kom sov .
- Cov me nyuam me me: Subblimation nce ntau dua kev ua pa kom tiv thaiv cov chaw muaj txiaj ntsig, thiab saib xyuas cov sensors kom tsim nyog {}}
Kev ua raws kev nyab xeeb txoj kev nyab xeeb tsis yog cuam tshuam rau ob tus neeg ua haujlwm thiab khoom siv .
Xaus:
Qhov loj me ntawm cov dej khov cov dej khov tau tuaj yeem siv rau cov khoom siv tu lossis cov khoom siv kom muaj zog, koj tuaj yeem ua tiav sai dua, nyab xeeb, thiab ntau dua nqi-siv tau tu ua kom zoo {4 4}}} allt download peb tam sim no kom paub ntau ntxiv txog pebdej khov qhuav blasting daws .
