1 Taw qhia
Nrog rau kev txhim kho sai ntawm kev lag luam txhuas thiab kev nce qib txuas ntxiv rau txhuas cov tshuab sib txuas lus puab pwm txhuas aluminium extrusion tau tshwm sim. Porous pwm aluminium extrusion tau zoo heev txhim kho kev ua haujlwm ntawm extrusion thiab kuj tseem muaj cov txheej txheem pwm thiab cov txheej txheem extrusion.
2 Kev Txiav Txim Siab
Qhov cuam tshuam ntawm cov txheej txheem extrusion ntawm kev ua tau zoo ntawm cov khoom siv puab tsaig puab txhuas mas feem ntau tau xav hauv kev tswj hwm ntawm peb yam: qhov ntsuas kub, thiab ntsuas kub.
2.1 sov kub
Cov khaub ncaws tsis zoo yog qhov cuam tshuam tseem ceeb rau kev rho tawm cov zis tawm. Hauv kev tsim khoom tiag tiag, cov tshuab extrusion tau siv mus rau saum npoo discoloration feem ntau tau siv cov nplaim hluavtaws ntau. Ntau-blendaces muab cov khoom sib txuam zoo dua thiab ua kom cua sov kom huv si nrog cov khoom rwb thaiv tsev zoo. Ib qho ntxiv, txhawm rau kom ntseeg tau tias siab ua haujlwm, qhov "tsawg kub thiab kev kub ceev" yog feem ntau ua haujlwm. Hauv qhov no, qhov ntsuas kub thiab txias thiab tawm kom sib phim rau kev hloov pauv ceev, nrog kev hloov pauv mus rau hauv tus account hloov pauv thiab cov xwm txheej ntawm qhov chaw seem. Cov chaw kub tsis pub dhau yog nyob ntawm cov txheej txheem ntau lawm, rau cov ntxaij puab ntau dua, nrog cov tuag tiaj tus me me los ntawm 10-20 ° C sib piv rau kev sib cais tuag.
2.2 pwm kub
Raws li kev paub txog kev tsim khoom, pwm kub yuav tsum tau tswj hwm ntawm 420-450 ° C. Lub sijhawm cua sov ntau dhau tuaj yeem ua rau pwm yaig thaum lub sijhawm ua haujlwm. Tsis tas li ntawd, kev pluah tsim kom tsim nyog thaum muaj cua sov yog qhov tseem ceeb. Cov pwm yuav tsum tsis txhob sib cais ib yam nkaus ua ke, tawm qee qhov chaw nruab nrab ntawm lawv. THAIV KHOOM RAU LUB CUA AIRFLOW NTAWM COV PWM RHAV LOSSIS TSIS TXAUS SIAB Yuav ua rau muaj cua sov thiab tsis sib haum.
3 muab cov khoom siv
Pwm Tsim, Pwm, thiab Pwm Siv, thiab Moulding Kev kos duab los ntawm kev coj ua ntau lawm thiab sib koom pwm tsim kev paub, peb soj ntsuam cov cai no.
3.1 Pwm Tsim
Pwm yog lub hauv paus ntawm cov khoom tsim thiab ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov duab, qhov tseeb yog, zoo nkauj, thiab cov khoom siv ntawm cov khoom. Rau cov ntxeem tau pwm nyob nrog qhov chaw siab zoo, txhim kho cov kev tso ua kom zoo nkauj thiab ua kom zoo nkauj ntawm cov choj txuas ntxiv kom tsis txhob muaj cov hniav sib txawv kom tsis txhob muaj qhov zoo nkauj zoo nkauj ntawm qhov profile. Ib qho ntxiv, rau cov tuag rov qab, siv cov ntws rov qab rau kev tsim qauv tuaj yeem ua kom cov hlau ua kom haum rau cov kab noj hniav tuag.
3.2 Pwm
Thaum pwm kev ua lag luam, txo qis kev tiv taus hlau ntws ntawm cov choj yog qhov tseem ceeb. Milling cov docation bridges du tau ntseeg tau qhov tseeb ntawm tus choj choj txoj haujlwm thiab pab kom ua tiav cov hlau sib dhos. Rau cov profiles nrog cov kev xav tau siab zoo, xws li cov vaj tsev hnub ci, xav txog qhov ua kom siab dua ntawm cov txheej txheem vuam kom ntseeg tau zoo.
3.3 Mould txij nkawm
Kev kho ib txwm mould yog ib qho tseem ceeb. Polishing cov pwm thiab siv Nitrogenization txij nkawm tuaj yeem tiv thaiv cov teeb meem xws li tsis sib haum xeeb hauv cov chaw ua haujlwm ntawm cov pwm.
4 dawb paug zoo
Qhov zoo tshaj ntawm qhov tsis zoo muaj qhov tseem ceeb tshaj plaws rau cov khoom lag luam zoo, ntxiv kev ua kom zoo, thiab pwm puas. Cov tsis zoo yuav ua rau muaj teeb meem zoo xws li grooves, discoloration tom qab oxidation, thiab txo pwm pwm. Blank zoo suav nrog cov muaj kev sib xyaw kom zoo thiab kev sib xyaw ntawm cov ntsiab lus, ob qho tib si uas cuam tshuam nrog cov extrusion tso tawm thiab ua tau zoo.
4.1 Kev teeb tsa kev teeb tsa
Siv cov vaj huam sib luag solar ua piv txwv, mg, thiab FE hauv cov khoom tshwj xeeb uas tsis muaj kev cuam tshuam cov khoom siv. Tag nrho cov nyiaj thiab kev sib npaug ntawm SI thiab mg yog qhov tseem ceeb heev, kev tswj hwm Si + MG hauv ntau yam ntawm 0.82-0.90% yog qhov tsim nyog rau tau txais cov khoom lag luam zoo.
Hauv kev tsom xam ntawm cov kab lus tsis raws nraim rau cov hnab tawv hnub ci, nws tsis ruaj khov los yog tshaj qhov txwv, cuam tshuam rau qhov chaw zoo. Qhov sib ntxiv ntawm cov ntsiab lus nyob rau hauv lub khw melting yuav tsum tau ua nrog kev saib xyuas kom tsis txhob muaj qhov tsis meej lossis ntau tshaj ntawm cov kab tseem ceeb. Hauv kev lag luam pov tseg kev ua haujlwm, cov khib nyiab pov tseg xws li cov khoom khib nyiab xws li cov khoom siv oxidation, thiab cov tshuaj thermal thiab cov khoom siv thermal ua ke. Oxidized profiles yuav tsum tau siv tshwj xeeb dawb, thiab feem ntau tsis muaj pov tseg, yuav muab ntxiv thaum cov ntaub ntawv muaj txaus.
4.2 Dawb Cov Txheej Txheem
Txhawm rau kom tau txais cov kab ke zoo, nruj me ntsis ua rau cov txheej txheem yuav tsum tau rau nitrogen purging ntev thiab txhuas lub sijhawm yog qhov tseem ceeb. Cov khoom siv alloy feem ntau ntxiv rau hauv block daim ntawv, thiab kev sib xyaw kom huv yog siv los ua kom nrawm lawv cov kev sib cais. Kev sib xyaw kom zoo tiv thaiv kev tsim ntawm cov cheeb tsam muaj cov chaw ntawm cov khoom ntawm almoy.
Tag
Aluminium alloys tau dav siv hauv cov tsheb hluav taws xob tshiab, nrog cov ntawv thov hauv cov qauv txheej txheem thiab qhov chaw xws li lub cav, lub cav, thiab lub log. Kev siv cov aluminium nce nyob hauv kev lag luam tsheb tau tsav los ntawm kev thov kom muaj zog thiab ib puag ncig nrog kev nce qib hauv aluminium thev naus laus zis. Rau profiles nrog cov khoom muaj nuj nqis zoo, xws li txhuas roj teeb xav tau, txhim kho kev ua tau zoo ntawm cov tuam txhab kev hloov pauv hauv lub zog hloov pauv.
