Dab tsi yog qhov chaw qhib ntawm lub qhov taub perforated hlau ntawv?
Qhib cheeb tsam yog tag nrho cheeb tsam ntawm lub qhov muab faib los ntawm tag nrho cheeb tsam ntawm cov hlau ntawv thiab ib txwm qhia los ntawm persent.Qhib cheeb tsam qhia txog qhov piv ntawm perforated qhov ntawm cov ntawv hlau.Piv txwv li, ib daim ntawv hlau perforated yog 1m * 2m 锛寃ith puag ncig lub qhov ntawm 2 hli txoj kab uas hla, 60 ° stagger, 4 hli nruab nrab nrug.Qhov qhib ntawm daim ntawv no yog 23%, txhais tau tias tag nrho cheeb tsam ntawm lub qhov punched yog 0.465 Luas 1 m * 2 m * 23% 锛thiab 77% ntawm daim ntawv yog cov khoom siv.
Qhov feem pua ntawm qhov chaw qhib feem ntau yog nyob nruab nrab ntawm 30% thiab 50% txawm hais tias muaj ntau qhov chaw qhib muaj nyob ntawm qhov perforation.Txawm li cas los xij, tseem muaj ib qho tseem ceeb uas yuav tsum tau xav txog thaum xav tau qhov chaw qhib loj dua.Qhov loj dua qhov chaw qhib, qhov ntau cov khoom siv distortion tshwm sim, tshwj xeeb tshaj yog thaum tus qauv perforated ciam teb los ntawm cov npoo ntawm tag nrho plaub sab.Vim tias xuas nrig ntaus qhov hauv cov ntawv hlau ntxiv kev ntxhov siab yuav ua rau muaj kev cuam tshuam ntawm cov khoom.Yog li qee zaum qhov feem pua ntawm qhov chaw qhib yuav tsum qis dua kom muaj zog ntxiv thiab flatness ntawm cov ntawv hlau perforated tshwj xeeb tshaj yog thaum galvanizing.
Yuav ua li cas xam qhov qhib cheeb tsam ntawm puag ncig lub perforated hlau ntawv?
Round qhov perforated hlau ntawv muaj nyob rau hauv peb cov qauv: 60 ° staggered, 45 ° staggered thiab ncaj kab.
Round Qhov-60 ° staggered
Tus qauv 60 ° staggered yog qhov nrov tshaj plaws faib raws li nws muaj ntau dua cov qauv muaj zog thiab muaj ntau yam ntau yam ntawm thaj chaw qhib.
