Cov kab ntau lawm ntawm high-resistance multi-layer squeezing ntsiav tshuaj tuaj yeem ua rau cov viscosity soluble ntawm PP, AD, thiab EVOH cov khoom xyaw sib txawv, los ntawm thermal fusion ntawm PP, AD, thiab EVOH los ntawm peb lub squeezers ntawm A, B, thiab C. Lub distributor tsim PP / AD / EVOH / AD / PP khoom txheej. Lub tswv yim tsim qauv ntawm cov khoom xa tawm tau hloov kho cov nplooj los kho cov nyias nyias thiab kev faib ua feem ntawm cov txheej nruab nrab hauv nruab nrab ntawm ob txheej. Nyob rau hauv lub distributor, xaiv ib co grooves los txhim kho tag nrho cov ndlwg ntawm cov khoom los kho, thiab kho cov nyias thickness ntawm nruab nrab txheej. Tom qab cov tailoring ntawm ntug ntawm ntug ntawm lub nyem, lub squeezing neeg rau zaub mov warehouse yog xa rov qab mus rau qhov ntau lawm.
High-resistant ob-txheej co-squeezed tawm -of -sheet tshuab khoom Cov khoom ntim yas ntawm cov khoom rhiab ntau rau cov khoom siv oxygen. Lub sij hawm cia ntawm cov khoom rhiab heev ntawm cov khoom siv tsis yog nyuaj li cov khoom siv hlau thiab cov khoom siv iav.
Cov txheej txheem tseem ceeb ntawm cov tshuab thiab cov khoom siv: Cov txheej txheem nyias thiab tuab ntawm cov ntaub ntawv raw yog rhuab thiab nyem tawm raws li lub tshuab loj loj (C), thiab lub tshuab hydraulic sai hloov lub mesh kom ncav cuag tus neeg xa khoom. Lub tshuab (A) thiab lub boiler auxiliary tshuab (B) extruder nrog sov melting thiab squeezing, thiab cov mesh yog converged nyob rau hauv distributor, stabilized rau lub co-squeeze cav tsim, thiab peb-roller hmoov pads yog tsau rau refrigerate. Tau kawg, tom qab lub tub yees, cov ntawv xa mus rau hauv cov khoom siv inverter los ntawm cov traction band roller, thiab lub vaj huam sib luag yog ntim raws li cov khoom tsim khoom (C \ B \ A \ B \ C daim qauv), thiab txiav cov ntug khib nyiab. ncaj qha nkag mus rau ntawm ntug ntawm ntug kom nkag ncaj qha mus nkag Tom qab lub crusher rov qab lub extruded neeg rau zaub mov warehouse, nws kuj yuav bundled los ntawm lub squeezed siege los ntawm lub tso tseg sab yob cov khoom.
Tus yuam sij rau ob-txheej squeezing yog cov khoom faib. Lub thermal fusion ntawm PP, AD, thiab EVOH los ntawm peb lub squeezers los ntawm peb lub squeezers los ntawm A \ B \ C yog tsim los ntawm ib tug distributor los tsim PP / AD / EVOH / AD / PP khoom. Tus yuam sij rau txheej txheej yog cov txheej txheem ntws ntws, uas ua rau PP txheej sib npaug sib npaug rau ib lossis tsib txheej, AD txheej muab faib ua ob lossis plaub txheej, thiab EVOH txheej yog txheej sab hauv. Lub tswv yim tsim ntawm tus neeg faib khoom ntws channel tau kho cov nplooj los kho cov nyias nyias thiab kev faib ua feem ntawm cov txheej hauv nruab nrab ntawm ob txheej. Tom qab lub sijhawm, siv lub twj tso kua mis soluble iav roj kom muaj nuj nqis tsom xam thiab kev tswj xyuas. Solute viscosity ntawm PP, AD, thiab EVOH ntawm qhov kub ntawm cov khoom siv lub raj yog txawv, uas yuav ua rau lub thickness ntawm kab rov tav ntawm txhua txheej ntawm daim ntawv. Tag nrho cov ntws ntawm cov khoom raug kho, thiab lub thickness ntawm nruab nrab ntawm cov khoom yog kho.
Ob txheej txheej txheej ntawm cov khoom sib txawv yuav tsum tau muab txiav rau ntawm ob sab. Cov seem ntawm trimming muaj cov khoom sib txawv ntawm ob txheej txheej. Txhawm rau kom ua tiav qhov kev sib tw ntawm ntug ntawm ntug ntug, raws li kev txhim kho ntawm kev nyem ntawm ciam teb strip, hloov cov distributor txaus channel, kom cov binding lub cev muaj kev nyab xeeb raws ntawm ob sab, cov kua dej thiab cov sib xyaw ua ke nyob rau hauv sideline. streaming channel kev nyab xeeb channel Hom txheej txheej converges rau hauv ib qho khoom ntawm qhov nkag thiab tawm ntawm qhov tawm. Lub hnab ntim dej nyob rau sab ntawm lub cev ntug yog ntawm ob sab ntawm cov khoom. Lub kaum sab xis ntawm cov ces kaum uas raug txiav thaum cov npoo yog cov khoom siv tib yam ntawm cov kua dej, uas yog qhov tsim nyog rau kev yuav khoom.
