Yuav Ua Li Cas Tshem Tawm Tawm Tus Neeg Saib Xyuas Residue los ntawm Composite Moulds Nrog Qhuav Ice

Tso tus neeg sawv cev residue ntawm cov pwm sib xyaw ua rau mob taub hau tiag tiag hauv kev tsim khoom. Hauv aerospace, automotive, thiab cua zog tsim, tsim los ntawm silicone-raws li, siv quav ciab-raws li, los yog ib nrab- cov neeg tso tawm mus tas li ua rau cov khoom nplaum, qhov tsis xws luag, flash, thiab lub neej luv luv. Kev tu cov txheej txheem ib txwm siv - cov kuab tshuaj tshuaj, phau ntawv scraping, los yog abrasive blasting - feem ntau yuav tsum tau txias pwm, disassembly tag nrho, thiab ntev downtime. Qhov phem tshaj, lawv muaj kev pheej hmoo ua rau cov khoom siv sib xyaw ua kom zoo nkauj lossis tawm hauv qhov chaw sib kis.

Qhuav dej khov blastingmuab kev daws teeb meem. Nws tshem tawm tus neeg sawv cev residue los ntawm cov pwm sib xyaw thaum lub cuab yeej kub thiab hauv xovxwm. Cov txheej txheem siv cov khoom CO₂ pellets uas cuam tshuam, embrittle, thiab sublimate, nqa cov kab mob tsis muaj kev puas tsuaj lossis cov khoom pov tseg. Ntau lub khw muag khoom tam sim no siv nws los txiav lub sijhawm tu txog li 75% thiab ua kom cov pwm khiav ntev dua ntawm kev saib xyuas.

Yog vim li cas tso tus neeg sawv cev residue dhau los ua qhov teeb meem loj ntawm cov pwm sib xyaw

Composite pwm, tshwj xeeb tshaj yog cov uas ua los ntawm epoxy tooling board, carbon fiber composites, los yog siab -precision hlau inserts, thov kom nruj nto tolerances. Cov neeg ua haujlwm tso tawm tau siv txhua lub voj voog los pab cov khoom ua kom huv. Thaum lub sij hawm, cov neeg ua hauj lwm no kho, sib tov nrog resin tawm- gassing, thiab tsim nyob rau hauv kab noj hniav, vents, parting kab, thiab nyuaj- mus rau - mus txog qhov chaw.

Qhov tshwm sim tshwm sim sai sai. Cov vents txhaws ua rau luv luv thiab hlawv cov cim. Accumulated residue alters nto tiav, ua rau pom qhov tsis xws luag ntawm qhov kawg. Hauv qhov xwm txheej hnyav, nws yuam kev hloov pwm thaum ntxov, uas yog kim rau cov cuab yeej loj xws li cua tshuab pwm lossis cov khoom siv dav hlau.

Cov kev coj ua niaj hnub ua rau qhov teeb meem loj dua. Cov tshuaj ntxuav tes tsim cov khoom pov tseg uas tsim kev puas tsuaj thiab tuaj yeem ua rau qhov chaw rhiab heev. Mechanical txoj kev hnav down qhov tseem ceeb. Qhov tseem ceeb tshaj plaws, lawv xav tau cov pwm kom txias thiab tawm ntawm cov xovxwm, tua lub sijhawm ntau lawm. Hauv siab -kev tsim khoom sib xyaw ua ke, lub sijhawm poob qis no ntxiv nrawm.

Cov dej khov qhuav qhuav hais txog cov teeb meem no ncaj qha los ntawm kev tso cai rau hauv - qhov chaw tu ntawm qhov chaw ua haujlwm kub. Tsis txias - cia. Tsis muaj disassembly. Tsuas yog tshem tawm cov tshuaj tso tawm thiab cov residue residue.

Yuav Ua Li Cas Qhuav Ice Blasting Ua Haujlwm ntawm Composite Tooling

Qhuav dej khov blasting cleans los ntawm peb ib txhij ua. Ua ntej, qhov siab - nrawm pellets xa cov kinetic cuam tshuam uas tawg thiab loosens cov seem seem. Thib ob, qhov txias txias ntawm -78.5℃ua rau thermal shock, ua rau tus neeg tso tawm nkig kom nws sib cais yooj yim dua los ntawm cov pwm nto. Thib peb, thaum cuam tshuam cov dej khov qhuav sublimes tam sim ntawd mus rau hauv cov pa, tsim kom muaj micro-expansion nyhuv uas nqa cov khib nyiab pov tseg.

Dab tsi ua rau txoj kev no haum rau cov pwm sib xyaw yog nws tsis yog -abrasive xwm. Tsis zoo li cov xuab zeb lossis iav hlaws blasting, cov dej khov qhuav tsis tuaj yeem ua rau pwm nto lossis hloov qhov tseem ceeb roughness qhov tseem ceeb (Ra feem ntau nyob hauv 0.1μm variation). Nws ua haujlwm ntawm Chav Kawm A mus rau Chav Kawm D tiav thiab ua haujlwm cov geometries nyuaj hauv RTM, prepreg layup, thiab infusion tooling.

Cov txheej txheem kuj yoojyim tsis muaj cov khib nyiab thib ob. CO₂ tsuas yog tig mus rau cov pa roj thiab cov pa tawm mus, yog li tsis muaj dej noo, tsis muaj tshuaj lom neeg, thiab tsis muaj xov xwm los ntxuav tom qab. Qhov no ua kom cov pwm npaj rau tam sim ntawd rov- daim ntawv thov tso tawm tus neeg sawv cev thiab rov qab mus rau ntau lawm.

Kauj ruam-los ntawm- Cov kauj ruam qhia: Tshem tawm Cov Tso Tawm Tso Tawm Nrog Dej Khov Qhuav

Ntawm no yog cov tswv yim ua ntu zus kuv pom zoo raws li kev paub dhau los nrog cov cuab yeej sib xyaw.

Kev npaj ua ntej ntxuav

Pib nrog kev nyab xeeb. Yuav tsum hnav cov hnab looj tes insulated rau cov dej khov qhuav qhuav, tsom iav kev nyab xeeb, ntev- tes tsho tiv thaiv- khaub ncaws zoo li qub, thiab tsis yog- khau khiab. Ua hauj lwm hauv qhov dej - qhov chaw cua nrog cov pa tawm kom ua kom CO₂ qib nyab xeeb - cov dej khov qhuav sublimates sai thiab tuaj yeem tso pa oxygen.

Tshawb xyuas koj cov khoom siv. Siv 3-5 hli qhuav ice pellets rau feem ntau cov pwm ua haujlwm. Cov blocks loj dua yuav tsum tau crushed ua ntej kom zoo sib xws. Cov dej khov qhuav blaster xav tau kev hloov kho siab, feem ntau teem ntawm 0.3-0.6 MPa. Muaj cov txhuam mos, cov phom cua compressed, thiab cov khoom me me ntawm cov ethanol uas tsis muaj dej txaus npaj rau cov tawv nqaij tawv.

Tshawb xyuas cov pwm ua ntej. Saib rau tej kab nrib pleb lossis qhov chaw tsis muaj zog hauv qhov chaw sib xyaw. Txheeb xyuas thaj chaw hnyav hnyav - feem ntau cov kab noj hniav, qhov cua, thiab cov kab sib cais - siv kev tshuaj xyuas qhov muag lossis UV teeb yog tias tus neeg sawv cev tso tawm muaj cov fluorescent tracers.

Qhov tseeb blasting txheej txheem

Teem koj cov parameter kom zoo:

• Siab: 0.3-0.6 MPa (pib qis ntawm polished lossis coated nto)
• Qhov deb: 30-50 cm los ntawm lub nozzle mus rau pwm
• Lub kaum sab xis: 75℃-90℃rau qhov siab tshaj plaws; qaij rau tob recesses

Txav lub nozzle nyob rau hauv tsis tu ncua cheb hla dhau qhov seem seem. Tsom ntsoov rau cov vents thiab nruj geometries uas tso tawm tus neeg sawv cev nyiam mus sau. Rau cov thicker buildup los yog kho prepreg residue, siv qhov chaw luv luv blasts ua ke nrog maj mam txhuam los pab tshem tawm cov khoom.

Ntxuav thaum pwm tseem kub thaum twg los tau. Qhov no txhim kho kev tso tawm tus neeg sawv cev embrittlement thiab tshem tawm qhov xav tau rov ua kom lub cuab yeej tom qab.

Tshaj tawm -Txoj kev ntxuav thiab pov thawj

Tom qab blasting, tos 5-10 feeb rau cov dej khov qhuav qhuav kom tag nrho sublimate thiab xoob cov khib nyiab kom poob. Siv txhuam txhuam los yog rab phom cua qhuav kom tshem tawm cov khoom uas tsis pub dawb - tsis txhob siv cov cuab yeej txhuam.

If stubborn organic residue remains, wipe lightly with a cloth dampened in anhydrous ethanol. This dissolves leftover release agent components without soaking the mold.

Thaum kawg, tshuaj xyuas qhov chaw. Nws yuav tsum tshwm sim huv si thiab tsis pub dawb los yog oily films. Rau cov ntawv thov tseem ceeb, ua qhov ntsuas dej ceev ntawm lub kaum sab xis - lub kaum sab xis qis qhia tau tias muaj kev huv zoo dua thiab kev npaj nto rau lub voj voog ntau lawm tom ntej.

Feem ntau cov pwm sib xyaw rov qab los rau kev pabcuam hauv 30-60 feeb siv txoj kev no.

Qhuav Ice Blasting vs. Lwm yam Pwm ntxuav txoj kev

Thaum xaiv ib txoj hauv kev tu rau cov pwm sib xyaw, qhov sib txawv tseem ceeb hauv kev ua haujlwm txhua hnub.

Cov tshuaj solvents dissolves tso cov neeg ua haujlwm tab sis tsim cov teeb meem pov tseg thiab kev pheej hmoo ntawm qhov etching los yog cov khoom seem hauv qhov pores. Mechanical scraping los yog sanding tshem tawm cov khoom tab sis maj mam hnav cov pwm kam rau ua thiab xav kom tshem tawm tag nrho cov pwm los ntawm cov xovxwm. Laser tu tuaj yeem ua tau meej tab sis feem ntau strips tiv thaiv cov txheej txheem thiab tawm tsam nrog cov polished los yog cov khoom sib xyaw ua ke.

Qhuav dej khov blasting sawv sib nrug vim nws ua haujlwm hauv online ntawm kev ua haujlwm kub. Koj zam lub sij hawm ntawm cooldown thiab reassembly. Qhov uas tsis yog - abrasive nkaus khaws cia qhov chaw tiav thiab qhov loj me. Tsis muaj cov khib nyiab thib ob txhais tau tias tsis muaj cov kauj ruam tu ntxiv ua ntej qhov txuas ntxiv mus.

Hauv kev xyaum, cov khw tshaj tawm tsawg dua qhov tsis lees paub thiab lub neej pwm ntev dua thaum lawv hloov mus rau kev tu dej khov qhuav.

Cov txiaj ntsig tiag tiag, kev txiav txim siab ntawm rooj plaub, thiab cov ntawv ceeb toom kev nyab xeeb

Nyob rau hauv aerospace cov qauv pwm thiab cov cuab yeej cua tshuab, cov dej khov qhuav blasting tsis tu ncua tshem tawm tus neeg sawv cev thiab cov resin buildup yam tsis muaj kev cuam tshuam qhov raug. Automotive teeb pom kev zoo thiab sab hauv vaj huam sib luag pwm pom txo qhov tsis xws luag tom qab tu zoo ib yam.

Txoj kev ci ntsa iab ntawm cov duab sib xyaw ua ke uas cov cuab yeej tsoos tsis tuaj yeem ncav cuag yam tsis muaj kev cuam tshuam. Vents nyob twj ywm qhib, cov kab sib cais nyob twj ywm ntse, thiab tag nrho cov seem seem poob.

Txawm li cas los xij, ob peb lub ntsiab lus tsim nyog tau txais kev saib xyuas. Ib txwm sim ib qho chaw me me ua ntej ntawm cov pwm tshiab los yog coated kom paub meej tias tsis muaj cov tshuaj tiv thaiv saum npoo. Cov pa roj carbon monoxide tuab heev yuav xav tau ntau qhov kev hla los yog kev pab cuam lub teeb ethanol. Cov dej khov qhuav yuav tsum tau muab cia rau hauv cov thawv insulated thiab siv tsis pub dhau 24 teev kom txo qis sublimation poob.

Kev nyab xeeb tseem tsis yog -negotiable. Kev ua pa kom zoo tiv thaiv CO₂ buildup. Cov neeg ua haujlwm xav tau PPE kom raug thiab kev cob qhia yooj yim ntawm kev teeb tsa siab. Thaum ua tiav lawm, cov txheej txheem yog ncaj qha thiab rov ua dua.
