Vertical Kneader vs. Kab rov tav Kneader
Hauv kev lag luam xws li yas, roj hmab, tshuaj lom neeg, kev ua zaub mov, thiab cov khoom sib xyaw, lub tshuab kneader yog ib qho khoom siv tseem ceeb rau kev sib tov, ua yas, thiab sib xyaw cov khoom siv. Raws li kev taw qhia ntawm cov ncej sib tov, cov tshuab kneader feem ntau yog muab faib ua kab rov tav thiab ntsug . Kev nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb rau kev xaiv cov khoom siv kom raug thiab kev ua kom zoo dua qub. Nov yog kev sib piv ntxaws ntxaws:
1. Cov Qauv thiab Txoj Cai Ua Haujlwm
Kab rov tav Kneader
Qauv : Nws muaj ob lub hniav Z-puab lossis Sigma-puab kab rov tav uas tau teeb tsa sab hauv lub qhov kab rov tav W-puab.
Txoj Cai Ua Haujlwm : Ob lub hniav tig mus rau ib leeg ntawm qhov ceev sib txawv. Qhov kev ua no yuam kom cov khoom siv rov ua dua, ncab, thiab txiav raws ob qho kev taw qhia axial thiab radial, tsim cov kev sib xyaw ua ke thiab cov yas. Cov khoom siv raug tig tas li hauv lub chamber, ua tiav kev sib kis sib npaug ntawm ob qho tib si macro thiab micro theem.
Ntsug Kneader
Qauv : Cov ncej sib tov tau teeb tsa ntsug. Cov hom feem ntau suav nrog ib lub ncej, tab sis qhov tsim qauv zoo dua yog hom planetary ob lossis ntau lub ncej. Lub thoob sib tov feem ntau yog zoo li lub thoob thiab feem ntau tshem tawm.
Txoj Cai Ua Haujlwm : Hauv kev tsim qauv planetary, ib lossis ntau lub hniav sib tov (feem ntau nruab nrog cov cuab yeej khawb phab ntsa) tig ib ncig ntawm qhov chaw nruab nrab ntawm lub qhov thaum tib lub sijhawm tig ntawm lawv tus kheej axes ntawm qhov ceev ceev. Qhov kev txav mus los nyuaj no ua kom txoj kev sib tov npog tag nrho lub qhov tsis muaj qhov chaw tuag, muab kev sib tov thiab kev sib tov zoo txawm tias rau cov ntaub ntawv viscosity siab.
2. Kev Ua Tau Zoo thiab Cov Yam Ntxwv Ua Haujlwm
Cov Txheej Txheem Tso Tawm :
Kab rov tav : Cov txheej txheem feem ntau suav nrog kev tilting tag nrho lub qhov rau kev pov tseg, tso tawm los ntawm lub tshuab extruder hauv qab, lossis los ntawm lub valve hauv qab. Rau cov ntaub ntawv viscosity siab, kev nias pab lossis kev pab los ntawm lub hau feem ntau xav tau.
Ntsug : Feem ntau cov dej tawm los ntawm kev txo thiab txav lub thoob uas tshem tau (hydraulically) lossis los ntawm lub qhov tso dej tawm hauv qab. Kev siv cov thoob uas txav tau ua rau kev hloov khoom thiab kev ntxuav yooj yim heev.
Kev Ntxuav thiab Kev Txij Nkawm :
Kab rov tav : Kev ntxuav tuaj yeem siv sijhawm ntau thiab siv zog ntau, tshwj xeeb tshaj yog thaum cuam tshuam nrog cov khoom siv viscosity siab uas lo rau ntawm cov hniav thiab phab ntsa.
Ntsug : Tus qauv tsim ntawm lub thoob uas tshem tau thiab cov hniav khawb uas ntxuav tau ntawm lub taub hau sib tov ua rau kev ntxuav huv si thiab yooj yim. Qhov no yog qhov zoo dua thaum hloov cov xim lossis cov qauv ntawm cov khoom ntau zaus.
Kev Sealing thiab Purity :
Kab rov tav : Cov bearings thiab cov foob nyob hauv qab lossis ib sab ntawm thaj chaw khoom siv. Siv sijhawm ntev, muaj kev pheej hmoo ntawm kev ua qias tuaj me me vim yog kev hnav thiab tsim kua muag.
Ntsug : Qhov no yog qhov zoo tseem ceeb. Lub zog nkag rau cov ncej sib tov yog los ntawm sab saud, txhais tau tias cov bearings thiab cov foob raug cais tawm ntawm cov khoom siv . Qhov no tshem tawm txhua qhov kev pheej hmoo ntawm kev ua qias tuaj ntawm cov roj nplua nyeem lossis cov khoom siv hnav, ua rau nws zoo tagnrho rau cov lag luam nrog kev huv si thiab kev ua kom huv si (piv txwv li, tshuaj, khoom noj, cov khoom siv hluav taws xob). Cov qauv tsav sab saud kuj pab txhawb kev ua tiav thiab tswj hwm qib siab.
3. Cov Cheeb Tsam Siv Tau
Lub Tshuab Sib Xyaws Kab Rov Tav : Qhov no yog hom siv dav tshaj plaws thiab siv rau txhua yam . Haum rau kev tsim khoom ntau, ua ntau pawg, lossis ua tas mus li ntawm cov khoom siv xws li:
Cov roj hmab silicone, cov polymers muaj molecular siab
Cov kua luam ntawv, cov xim, cov xim pleev xim
Lub hauv paus ntawm cov pos hniav
Cov khoom siv av nplaum, cov khoom siv carbon
Lub Tshuab Sib Xyaws Ntsug : Lub hom phiaj tseem ceeb yog rau cov khoom tshwj xeeb thiab cov khoom muaj nqis ntxiv , tshwj xeeb tshaj yog qhov twg cov txheej txheem nruj (nqus tsev, kub) thiab cov khoom huv si yog qhov tseem ceeb, xws li:
Cov khoom sib xyaw ua ke hauv aerospace (piv txwv li, sib xyaw epoxy resin nrog carbon fiber)
Cov polymers kho mob, cov ntaub ntawv kho hniav
Cov nplaum uas muaj zog thermal/electrical conductive, cov ntaub ntawv encapsulation chip
Cov roj av khov kho, cov khoom siv hluav taws xob rhiab heev (xws li pyrotechnics)
Kev Txheeb Xyuas
Qhov kev xaiv ntawm lub tshuab kneader kab rov tav thiab ntsug nyob ntawm koj cov khoom siv, cov txheej txheem xav tau, thiab cov hom phiaj tsim khoom.
Xaiv lub tshuab sib tsoo kab rov tav rau kev ua cov khoom loj uas siv nyiaj tsawg thiab muaj cov txheej txheem zoo. Nws yog ib qho khoom siv txhim khu kev qha.
Yog koj tab tom tsim cov khoom siv thev naus laus zis siab heev uas xav tau cov khoom siv huv si, sib tov sib npaug, thiab ruaj khov hauv qhov chaw nqus tsev. Nws tsim tsis muaj kuab paug thiab kev sib tov zoo ua rau nws yog qhov kev daws teeb meem zoo tshaj plaws rau cov ntawv thov siab heev.
