Multi-layer tshuab moldingtsim ib lub thawv ntim phab ntsa los ntawm ob lossis ntau txheej yas, txhua qhov ua haujlwm sib txawv - txheej txheej thaiv los thaiv cov pa oxygen lossis roj vapor, cov tub ntxhais siv rov ua dua los txiav nqi, cov tawv nqaij nkauj xwb kom huv si. Lawv tau co-extruded ua ke los ntawm ib lub taub hau tuag, yog li cov phab ntsa tawm seamless thiab fused. Koj xav tau nws thaum ib qho khoom siv tsis tuaj yeem ua txhua yam: lub tank roj uas yuav tsum tsis txhob xau vapor, lub raj mis kua txiv uas yuav tsum tau khaws cov pa tawm mus rau ib xyoos, lub thawv uas yuav tsum tau siv cov ntsiab lus rov ua dua yam tsis muaj qhov paug tawm sab hauv. Kinggle's KGH curved-arm machines khiav 1 mus rau 6 txheej ntawm cov thawv los ntawm 5 mus rau 30 litres.
Feem ntau lub raj mis yas yog ib qho khoom siv, ib phab ntsa, ua tiav. Squeeze HDPE los ntawm kev tuag, tshuab nws, eject. Yooj yim, pheej yig, thiab txoj cai rau feem ntau ntawm cov ntim khoom. Tab sis qee cov khoom thov rau ib yam dab tsi ib qho yas xwb tsis tuaj yeem muab. Thiab qhov ntawd yog qhov uas multi-layer tuaj.
Peb tau txais ib qho kev sib tw tsis tu ncua ntawm cov neeg yuav khoom uas tau hais tias lawv xav tau "co-extrusion" lossis "rau-txheej tshuab" thiab tsis paub tseeb tias qhov twg tiag tiag yuav lawv - lossis seb lawv puas tau muag. Yog li ntawm no yog cov dawb version: dab tsi cov khaubncaws sab nraud povtseg ua, thaum lawv tsim nyog nws, thiab thaum koj nyob nraum zoo dua nyob ib leeg-txheej.
Dab tsi "multi-layer" txhais tau tias ntawm lub Hoobkas hauv pem teb
Ib txheej yog ib qho extruder pub ib lub taub hau tuag nrog ib qho khoom siv. Multi-txheej yog ob peb extruders - txhua melting ib tug txawv resin ntawm nws tus kheej kub - tag nrho cov pub ib tug sib koomco-extrusion tuag taub hau. Hauv lub taub hau ntawd, cov dej ntws sib cais tau muab tso rau hauv cov khaubncaws sab nraud povtseg, yog li cov parison poob tawm lawm txheej. Ces nws tshuab raws nraim li lwm yam parison.
Xav txog nws zoo li plywood, tsuas yog cov khaubncaws sab nraud povtseg yog tsim thiab fused nyob rau hauv ib tug txhaj koob tshuaj tivthaiv es glued li los xij. Thiab ob lo lus koj yuav hnov - "ntau txheej" thiab "co-extrusion" - piav qhia tib yam los ntawm qhov sib txawv. Co-extrusion yog txoj kev; ntau txheej yog qhov tshwm sim.
Cov txheej suav feem ntau tsaws ntawm 2, 3, 5, lossis 6, thiab txhua tus lej muaj qhov laj thawj tom qab nws. Peb yuav mus txog qhov ntawd. Ua ntej, cov khaubncaws sab nraud povtseg lawv tus kheej.
Dab tsi txhua txheej yog tiag tiag rau
Txheej txheej txheej - yog vim li cas feem ntau cov haujlwm ntau txheej muaj nyob
Plain HDPE thiab PET yog qhov zoo ntawm ntau yam, tab sis lawv tau me ntsis ntxeem tau rau cov pa roj thaum lub sijhawm. Rau feem ntau cov khoom, leej twg mob siab rau. Ntawm cov hoob kawm, nws yog tag nrho cov ballgame. Oxygen creeping nyob rau hauv cov zaub mov spoils. Roj vapor creeping tawm ntawm lub tank ua txhaum txoj cai emissions thiab yog ib qho teeb meem kev nyab xeeb. Ib qho hnyav hnyav maj mam ua haujlwm ntawm phab ntsa uas nws tsis nyiam.
Qhov ntawd yog qhov txheej txheem txheej txheem kho.EVOH(ethylene vinyl cawv) yog tus qauv kub rau thaiv cov pa oxygen thiab hydrocarbons;PA(nylon) yog lwm txoj kev xaiv.

| 6 | Roj tso tsheb hlau luam, xav tau txoj haujlwm permeation | Barrier + ties + regrind + qauv |
Yog tias ib qho khoom siv twb tau raws li koj cov khoom txee lub neej, tshuaj tiv thaiv, thiab cov ntsiab lus rov siv dua, tsis txhob them rau cov txheej uas koj yuav tsis siv. Multi-layer yog ib qho cuab yeej rau cov teeb meem tshwj xeeb, tsis yog kev hloov kho rau nws tus kheej.
Dab tsi ntau txheej xav tau los ntawm lub tshuab
Ntawm no yog qhov txheej txheej daim duab yuav tsis qhia koj: txhua txheej xav tau nws tus kheej extruder pub rau co-extrusion tuag taub hau. Lub 6-txheej tank tuaj yeem txhais tau tias tsib lossis rau rau qhov extruders nyob ib ncig ntawm ib lub taub hau, txhua qhov sib txawv ntawm nws tus kheej qhov kub thiab txias, txhua qhov ntsuas qhov tseeb yog li nws cov txheej tseem nyob ib puag ncig ib puag ncig ntawm parison. Qhov ntawd yog ib lub tshuab sib txawv los ntawm ib txheej txheej lub raj mis kab.
Kinggle covKGH nkhaus-caj npab seriesyog tsim rau txoj hauj lwm no - 1 mus rau 6 txheej ntawm ntim ntawm 5 mus rau 30 litres. Cov lej tom qab nws yog tiag tiag: clamping quab yuam los ntawm 200 txog 300 kN thoob plaws qhov ntau, HDPE plasticising txog 300 kg / hr ntawm KGH30D, thiab MOOG-tswj phab ntsa-thickness programming. Qhov kev tswj lub thickness tseem ceeb tshaj plaws ntawm ntau txheej ntau dua li ib leeg, vim tias koj tuav ob peb txheej nyias - nrog rau qhov thaiv uas tej zaum yuav yog ib feem ntawm ib millimeter - rau spec tib lub sijhawm, txhua txoj hauv kev. Tau txais nws tsis ncaj ncees lawm thiab koj lub qhov thaiv nyias nyias tawm ntawm lub xub pwg nyom, uas yog qhov tseeb uas koj tsis xav tau qhov sib txawv.
Nws kuj tseem tsim nyog paub txog dab tsi nyob hauv qhov kev tswj hwm, vim tias muaj ntau txheej txheej nyob los yog tuag ntawm kev sib koom ua ke ntawm cov extruders.

Cov lus nug uas nquag nug
Dab tsi yog qhov txawv ntawm ntau txheej thiab co-extrusion tshuab molding?
Lawv piav tib yam. Co-extrusion yog txoj kev - ob peb extruders txhua yaj ib tug sib txawv resin thiab pub ib tug sib koom tuag lub taub hau, uas stacks lawv mus rau hauv concentric txheej. Multi-layer piav txog qhov tshwm sim - lub thawv phab ntsa ua los ntawm ob lossis ntau txheej fused. Yog tias phab ntsa muaj ntau tshaj ib txheej, nws tau co-extruded.
Vim li cas EVOH thaiv txheej faus rau hauv nruab nrab es tsis txhob ntawm qhov chaw?
Ob qho laj thawj. EVOH yog kim, yog li koj siv tsawg li tsawg tau - ib tug nyias nyias ua txoj hauj lwm barrier thaum pheej yig dua polyethylene ua rau tej. Thiab EVOH absorbs ya raws, uas rhuav tshem nws cov kev ua haujlwm tsis zoo, yog li nws yuav tsum tau tiv thaiv ob sab los ntawm lwm cov khaubncaws sab nraud povtseg. Muab tso rau ntawm qhov chaw yuav nkim nws thiab nthuav tawm rau cov av noo.
Dab tsi yog khi txheej thiab kuv tuaj yeem hla lawv?
Cov khaubncaws sab nraud povtseg yog cov nplaum nplaum nyias txheej uas cov ntaub ntawv sib txuas uas tsis tuaj yeem ua ke - EVOH thiab nylon tsis khi rau polyethylene ntawm lawv tus kheej. Hla lawv thiab cov khaubncaws sab nraud povtseg delaminate, tev tawm zoo li lub laminate ua tsis tiav. Lawv tsis xaiv tau. Lub tank roj rau 6-txheej suav nrog khi cov khaubncaws sab nraud povtseg ntawm txhua tus khub sib txawv, uas yog ib feem ntawm vim li cas nws muaj rau txheej.
Yuav tsum muaj pes tsawg txheej ntawm cov roj tank yas?
Feem ntau yog rau. Ib qho qauv tsim yog txheej txheej HDPE sab nrauv, txheej txheej rov qab, txheej khi, EVOH thaiv, txheej thib ob khi, thiab txheej HDPE sab hauv. Lub EVOH nres hydrocarbon vapor los ntawm permeating phab ntsa, khi cov khaubncaws sab nraud povtseg tuav nws mus rau polyethylene, thiab lub regrind txheej reuses ntau lawm trim.
Kuv puas tuaj yeem khiav cov khoom siv rov ua dua tshiab hauv lub thawv ntau txheej?
Yog, thiab ntau txheej yog qhov huv tshaj plaws los ua nws. Koj faus cov khoom siv rov qab los yog tom qab cov neeg siv khoom (PCR) nyob rau hauv nruab nrab txheej thiab khaws cov nkauj xwb, cov khoom noj-qib resin rau sab hauv thiab sab nrauv. Cov tub ntxhais uas siv dua tshiab yeej tsis kov cov khoom lossis qhia sab nraud, yog li koj tuaj yeem ntaus cov ntsiab lus rov ua dua tshiab yam tsis muaj kev pheej hmoo kis kab mob.
Tsis paub meej pes tsawg txheej koj cov khoom xav tau?
