Qhov sib txawv ntawm ib qho ntsia hlau thiab ntxaib ntsia hlau
Ib leeg ntsia hlau Extruder
Cov ntsia hlau ntawm ib leeg-ntsia hlau extruder yog tsim los ntawm cov ncej txuas cov ntsia hlau ntawm ntau yam qauv. Tag nrho cov ntsia hlau muaj peb ntu: ntu pub, ntu kneading thiab melting thiab homogenizing seem. Tom qab cov khoom nkag mus rau hauv lub thoob los ntawm qhov chaw nres nkoj pub, nws nkag mus rau cov khoom thauj, yaj thiab homogenizing txheej txheem hauv cov ntsia hlau, kom cov khoom hloov pauv los ntawm lub xeev xoob mus rau lub khob noom cookie tas li.
Nyob rau hauv ib leeg-ntsia hlau extrusion chamber, cov khoom yog nyob ze ze ntawm lub ntsia hlau, nyob rau hauv daim ntawv ntawm ib tug kauv nruam band, thaum lub ntsia hlau tig, cov khoom txav mus rau pem hauv ntej raws li ib tug ntsia hlau, tab sis thaum muaj kev sib txhuam ntawm cov khoom thiab cov ntsia hlau yog ntau dua qhov kev sib txhuam ntawm cov khoom siv thiab lub thoob, cov khoom siv yuav muab sib xyaw nrog cov ntsia hlau, thiab qhov no tsis tuaj yeem ua tiav rau pem hauv ntej extrusion ntawm cov khoom thiab cov nyhuv conveying. Thaum cov dej noo thiab roj cov ntsiab lus ntawm cov khoom yog siab dua, qhov kev sib txawv no pom tseeb dua. Txhawm rau zam cov teeb meem no, feem ntau ntawm ib leeg-ntsia hlau extrusion extruder tam sim no tau txais segmented, ib leeg thiab ob npaug ntsia hlau, lub nplhaib siab thiab lub nplhaib kneading staggered kev npaj ntawm kev sib xyaw ntawm cov ntsia hlau thiab sab hauv phab ntsa grooving chim kom hloov mus rau qhov hloov ntawm cov khoom siv. hauv kab noj hniav.
Twin-ntsia hlau extrusion puffer
Twin-ntsia hlau extrusion puffer yog ib hom multi-ntsia hlau extrusion puffer, uas yog tsim los ntawm ib leeg-ntsia hlau extrusion puffer. Nyob rau hauv lub chim ntawm ntxaib-ntsia hlau extrusion puffer, ob tug ntsia hlau yog muab tso rau ib sab, yog li nws yog hu ua ntxaib-ntsia hlau extrusion puffer. Raws li tus txheeb ze txoj hauj lwm ntawm cov ntsia hlau yuav muab faib ua meshing thiab non-meshing hom, meshing hom yuav muab faib ua ib feem meshing hom thiab tag nrho meshing hom; Raws li cov ntsia hlau rotating kev taw qhia tuaj yeem muab faib ua tib qho kev taw qhia ntawm kev sib hloov thiab thim rov qab ntawm ob hom, thim rov qab tuaj yeem muab faib ua ob hom sab hauv thiab sab nraud.
Co-rotating ntxaib-ntsia hlau siab zones yog txawv nyob rau hauv cov xwm, cov khoom nyob rau hauv lub puab kab noj hniav ntawm lub tes tsho los ntawm cov ntsia hlau rotating kev txiav txim, uas ua rau cov high-pressure thiab low-pressure zones. Obviously, cov khoom yuav ntws raws ob qho kev qhia los ntawm qhov chaw siab-siab mus rau qhov chaw uas tsis tshua muaj siab: ib qho yog nrog cov kev taw qhia ntawm cov ntsia hlau tig raws phab ntsa sab hauv ntawm lub tes tsho los ua rau sab laug thiab sab xis ob C-zoo li cov khoom ntws, uas yog lub ntsiab ntawm cov khoom; lwm yam yog los ntawm cov ntsia hlau kev koom tes ib feem ntawm qhov sib txawv los ua ib tug countercurrent. Yog vim li cas rau qhov countercurrent yog tias sab laug ntsia hlau rub cov khoom rau hauv qhov sib txawv, thiab txoj cai ntsia hlau rub cov khoom tawm ntawm qhov sib txawv, qhov tshwm sim yog tias cov khoom yog "∞" zoo li rau pem hauv ntej, hloov cov kev taw qhia ntawm cov khoom ntws. Qhov no tsis tsuas yog pab txhawb rau kev sib xyaw thiab homogenization ntawm cov ntaub ntawv, tab sis kuj ua rau cov hniav ntsia hlau nruab nrab ntawm cov grooves los tsim kev sib tsoo (piv txwv li, shear) thiab cov nyhuv dov, cov nyhuv calendering, cov nyhuv no tsawg dua piv nrog cov nyhuv rov qab ntsia hlau calendering. Tau kawg, cov nyhuv calendering yog me me, cov khoom siv ntawm cov ntsia hlau hnav thiab tsim kua muag kuj txo, cov khoom siv yog li los ntawm kev thauj mus los, shear, sib tov thiab lub plhaub plhaub cua sov, nyob rau hauv qhov kub thiab txias, siab siab kom ua tiav kev loj hlob, thiab thaum kawg. extruded tawm ntawm lub thoob.
Rov qab kev sib hloov ntxaib-ntsia hlau extrusion puffer feem ntau siv ob lub hau ntawm tib qhov loj, tab sis nrog cov lus qhia sib txawv. Qhov sib txawv ntawm qhov sib txawv ntawm sab hauv thiab sab nraud yog nyob rau hauv qhov sib txawv ntawm qhov chaw siab, qhov ntxaib-ntsia hlau sab hauv kev sib hloov ua rau lub siab rau lub siab thiab qis qis, cov khoom siv los ntawm cov ntsia hlau ntxaib, hauv qhov nkag yuav ua rau muaj kev kub siab heev, ua rau muaj teeb meem pub mis, qhov kev sib hloov sab hauv no tsis tshua siv; ntxaib-ntsia hlau sab nraud kev sib hloov ua kom lub siab rau lub siab qis thiab siab, yog qhov zoo rau kev pub mis ntawm cov khoom. Tab sis qhov kev sib hloov rov qab thiab tib qhov kev sib hloov piv rau cov khoom siv hauv cov ntsia hlau los ua cov khoom siv C-zoo li tus ntws tsis tuaj yeem txav los ntawm ib lub ntsia hlau mus rau lwm cov ntsia hlau, cov khoom tsim los ntawm qib sib xyaw yog txo qis, thiab nws tus kheej- kev tu lub peev xwm tsis zoo ib yam li kev sib hloov ntawm ntxaib-ntsia hlau zoo thiab ruaj khov.
Rov qab-rotating ntxaib-ntsia hlau vim yog qhov sib txawv ntawm qhov sib txawv ntawm sab saum toj thiab hauv qab, ua rau cov ntsia hlau rau ob sab ntawm kev sib cais quab yuam F, ntsia hlau nyob rau hauv qhov kev txiav txim ntawm F siab mus rau lub thoob, ua kom lub cev hnyav ntawm lub thoob thiab ntsia hlau. , thiab qhov siab dua qhov kev sib hloov ceev, qhov F ntau dua, qhov hnyav dua qhov hnav thiab tsim kua muag, yog li txwv qhov ceev ntawm cov ntsia hlau; thiab isotropic rotating ntxaib-ntsia hlau tsis muaj nyob rau hauv kev sib cais ntawm ob lub screws ntawm lub zog, yog li qhov hnav thiab kua muag me me, tuaj yeem ua haujlwm siab, thiab tuaj yeem ua tiav cov txiaj ntsig siab heev, yog li isotropic rotating ntxaib-ntsia hlau. yog siv ntau dua. Yog li ntawd, co-rotating twin-screw yog dav siv.
Lub hauv paus ntawm cov cua sov yuav tsum tau ua los ntawm cov khoom siv, ntxiv rau tib qhov ntawm cov ntsia hlau ib leeg, feem ntau los ntawm qhov sib txawv meshing; los ntawm meshing threads ntawm shear, extrusion thiab mixing, tshav kub tiam, thiab tshav kub homogenization. Qhov loj ntawm qhov sib txawv muaj qhov cuam tshuam zoo rau qhov zoo ntawm puffing, qhov sib txawv me me, lub zog shear yog loj, tab sis tus nqi ntawm cov khoom los ntawm kev txo qis; Qhov sib txawv yog qhov loj, cov khoom siv los ntawm kev nce, tab sis lub zog shear raug txo. Twin-ntsia hlau yuam conveying thiab tus kheej tu tus yam ntxwv, kom cov khoom nyob rau hauv lub chim ntawm lub luv nyob thiab niaj hnub; ntxaib-ntsia hlau zoo sib xyaw ua tau zoo kom cov khoom kom tau txais cov cua sov hauv lub sijhawm kom homogenize cov khoom kom ceev cov qib ntawm kev loj hlob, txo qhov hloov pauv ntawm cov khoom kub los txhim kho cov txiaj ntsig thiab zoo ntawm cov khoom puffed.
Twin-ntsia hlau extrusion puffing tshuab muaj qhov zoo ntawm adaptability, swb conveying thiab nws tus kheej tu, tab sis nws cov qauv yog complex, siab peev nqi, tus coj tus txij nkawm thiab kev khiav hauj lwm cov nqi kuj siab dua. Yog li ntawd, ntxaib-ntsia hlau extruder feem ntau yog siv nyob rau hauv zus tau tej cov cov dej thiab tsiaj pub nrog siab nqi-ntxiv; Tsis tas li ntawd, qee qhov tshwj xeeb hauv dej pub xws li cov khoom noj hauv dej, cov dej muaj roj ntau thiab cov khoom noj nrog cov ntim me me tab sis feem ntau cov qauv hloov tau yuav tsum tau siv ntxaib-ntsia hlau extruder rau ntau lawm.
