Txawm hais tias cov hlau perforated muaj nuj nqis rau lawv cov kev ua kom zoo nkauj, lawv muaj ntau cov txiaj ntsig dhau lawv cov tsos. Thaum lawv txhim kho li cas ib yam khoom yuav zoo, lawv muaj qhov tshwj xeeb ntxiv rau kev ua tau zoo dua. Txij li lawv tuaj yeem hloov kho tau yooj yim thiab hloov kom tau raws li ntau yam kev siv, lawv tau dhau los ua ib feem ntawm cov txheej txheem kev tsim khoom.
Cov txiaj ntsig ntawm Perforated Metals
Suab txhawb -
Perforated hlau ua haujlwm rau ntau lub zog ntawm lub teeb pom kev zoo. Ib qho ntawm lawv cov haujlwm tseem ceeb tshaj plaws yog txoj hauv kev rau lub suab haum. Perforated panels txo cov suab nrov tsis zoo los ntawm kev xa tawm nws. Qhov txiaj ntsig no yog qhov zoo rau thaj chaw ua haujlwm uas lub suab lus nrov nrov tuaj yeem ua rau txob taus thiab tsis xis nyob. Lub qhov ntxeem thiab cov nplaim ntu nto ntawm cov nplaim hluav taws xob ua kom tawg suab nrov thiab muaj sab hauv thiab sab nraum zoov siv.
Qhov cua -
Thaum lub tsev xav tau kev txhim kho nws qhov cua, nws siv perforated hlau tiv thaiv lub hnub tiv thaiv txhawm rau txhim kho cua thiab ua kom qhov chaw ntxoov ntxoo ntau dua. Txoj kev tiv thaiv vaj tse no ua rau txo tus nqi tsim nqi rau cua sov, cua tshuab, thiab cua txias. Cov ntsiab lus tseeb, perforated vaj huam sib luag tuaj yeem ua rau kwv yees li 30% rau 45% nyiaj.
Yim Txaus Siab -
Kev hloov kho kom haum ntawm cov hlau perforated muaj cov neeg tsim qauv thiab cov kws tsim qauv ntau yam ntawm cov hauv kev los txhim kho lub tsev tsim kho uas yuav kav ntev. Txij li cov hlau perforated tuaj yeem ua tshwj xeeb ua kom haum rau ib qho xwm txheej, lawv tuaj yeem tsim kho tsis zoo los muab cov qauv ua lub sijhawm ntev thiab nyob mus ib txhis. Kev tsim khoom thiab tsim tawm ntawm cov tshuab hluav taws xob perforated tsim cov khoom uas muaj zog dua qub thiab huab cua tiv taus ntau dua li lwm cov khoom siv rau tib lub hom phiaj.
Tsis pub twg paub -
Ib qhov tshwj xeeb ntawm perforated panels yog lawv lub peev xwm los muab qhov kev xav ntawm kev ceev ntiag tug yam tsis muaj qhov cuam tshuam zoo tshaj plaws. Kaw rau hauv cov phab ntsa thiab cov duab ntoo zoo li kev txiav thiab cais tawm ntawm qhov chaw ntshoo. Los txhim kho cov vaj huam sib luag perforated, ib qho chaw ua haujlwm tau muab faib tab sis tseem tso cai rau cov cua nkag thiab pom kev. Lub suab nrov thiab echoes tsis tu ncua thiab nqus tau los ntawm cov panels tsim kom muaj kev nyab xeeb zoo thiab siab.
Tsis tshua muaj kev cuam tshuam txog ib puag ncig -
Raws li qhov kev txhawj xeeb txog kev nyob ruaj khov thiab kev txuag loj hlob, cov neeg tsim qauv thiab cov tub txawg nrhiav tas li rau cov khoom uas yuav txo qhov cuam tshuam ib puag ncig. Cov hlau siv rau perforated vaj huam sib luag yog siv tau dua tshiab thiab txo qhov xav tau ntawm cov hlau tshiab rau cov phiaj xwm. Txij li lawv muaj lub neej ntev siv, perforated panels tsis tshua xav tau txij nkawm lossis raug kev txom nyem hnav. Cov xwm txheej no ua rau kom muaj kev lag luam thev naus laus zis txuas ntxiv thiab ua rau kom lawv lub neej ntev.
Ntau Lawm -
Hauv cov txheej txheem ntau lawm, kev ua tau zoo thiab kev ua tau zoo yog qhov tseem ceeb. Cov roj perforated ua haujlwm kom yooj yim hauv cov khoom xa thiab khaws cia. Kev tawm tsam tau tso cai rau cov cua thiab tiv thaiv cov khoom los ntawm muaj ib daim ntawv tsim-tsim lossis khaws khib nyiab. Cov pob tawb feem ntau, cov tsheb, thiab cov khoom siv tuav cov khoom siv rau kev siv ntau lawm yog ua los ntawm cov hlau tsis xeb, galvanized steel, lossis txias txias-kuav los tiag hlau.
Tawg hluav taws xob -
Cov khoom siv hluav taws xob thiab khoom siv hluav taws xob tsim tawm EMI thiab RFI hluav taws xob uas yuav tsum muaj nyob thiab tswj. Perforated shielding muab 99% attenuation ntawm EMI thiab RFI hluav taws xob nrog kev tiv thaiv kev tiv thaiv ntawm 40 decibels, uas yog qhov tsawg kawg nkaus rau cov ntawv thov. Cov duab yaj thaiv tau zoo heev ntawm 7 gigahertz.
Perforated Lub Zog Hlau
Lub zog ntawm perforated hlau yog ntsuas los ntawm kev sib piv lawv mus rau cov khoom hlau, lub tswvyim uas tau raug xa mus ua qhov sib txig sib luag ntawm cov khoom siv. Txhawm rau pab cov neeg tsim qauv txiav txim siab seb cov khoom siv perforated los siv, cov kws ua choj, ua cov khoom sib npaug nrog cov khoom kuaj.
Cov qauv muaj zog tshaj plaws rau cov hlau tsis huv nyob hauv qhov puag ncig uas yog staggered ntawm 60o, uas muab lub zog thiab ntau qhov chaw qhib. Siv cov txheej txheem thev naus laus zis, tus tsim qauv ntsuas lub zog ntawm cov khoom siv perforated piv rau cov khoom siv khov.
Cov ntaub ntawv perforated muaj lub zog sib txawv nyob ntawm cov kev taw qhia ntawm kev thauj khoom. Cov zis muaj zog ntawm cov ntaub ntawv perforated yog qhov ua haujlwm ntawm qhov tawm los muaj zog ntawm cov khoom siv dag zog. Qhov kev txiav txim siab ntawm lub zog ntawm cov ntaub ntawv perforated yog ua raws lawv qhov tuab raws li kev sib piv rau cov khoom ua kom zoo.
Ib qho tseem ceeb ntxiv yog qhov txhav ntawm cov khoom siv perforated, uas tseem tau muab xam los ntawm kev sib piv rau cov khoom qub. Siv lwm cov mis, cov neeg txiav txim siab txiav txim siab qhov tsim nyog tuab ntawm perforated vaj huam sib luag xws li tias nws muab tib qho txhav zoo li cov khoom khov.
Perforated Tus Qauv Hlau
Cov qauv rau perforated hlau tau tsim los pab cov neeg tsim qauv thiab engineers xaiv cov khoom lag luam kom raug rau lawv daim ntawv thov. Cov qauv rau kev tiv thaiv perforated hlau tau tsim los ntawm lub koom haum Industrial Perforators.
Ntawv thiab Cov Ntawv Loj -
Qhov dav thiab ntev yuav tsum ua raws cov qauv dav dav rau kev txiav plaub hau, uas yuav tsum suav nrog kev ncab ntawm cov khoom thaum tawg.
Hlau Thickness -
Txhua cov hlau uas siv hauv cov txheej txheem perforating tau ua raws li US Standard Gauge rooj.
Cov duab ntawm Perforations -
Txawm hais tias 60 ° puag ncig yog tus qauv ua qauv, muaj cov kev hloov pauv, uas suav nrog cov kab ncaj nraim thiab staggered siv cov duab sib txawv xws li plaub fab, qhov qhib, thiab kev siv ntau yam ntawm lwm cov kev xaiv.
Spacing ntawm Perforations -
Perforated tus qauv hlau muaj qee lub cheeb nrog qhov sib txawv tsim nyog nrog qhov chaw qhib uas yog hlau tau raug tshem tawm los ntawm cov txheej txheem perforation.
Qauv Perforation -
Cov qauv staggered feem ntau yog 45 ° lossis 60 ° thiab siv tau thaum cov phiajcim khoov txij li nws tso cai rau khoov cov qhov ntev tau yooj yim. Cov qauv ncaj yog kab thiab kab ntawv uas zoo ib yam li daim phiaj. Nws tsis zoo yog kev siv tus qauv ncaj rau kev khoov.
Ntug Paj -
Cov npoo tau muab tso rau ntawm txhua sab ntawm lub vaj huam sib luag. Nws yog ib txwm muaj cov npoo nyob rau sab thiab tsis yog sab saum thiab hauv qab, uas yooj yim rau kev teeb tsa.
Flatness -
Txhua tus ntoo perforated yog xa ncaj nraim thiab nquag plooj raws li qhov ntawm cov txheej txheem perforation. Raws li cov xwm txheej tshwj xeeb, kev hloov pauv ntawm flatness tej zaum yuav tsum tau kho kom tau raws li cov qauv tsim tshwj xeeb.
