HDPE yeeb nkab ntau lawm pib ntev ua ntej cov yeeb nkab mus txog lub tshuab nqus tsev sizing lub tes tsho los yog lub tank txias.

Thaum pib ntawm cov txheej txheem, cov khoom siv tsuas yog HDPE resin hauv daim ntawv pellet. Lub tshuab extrusion yuav tsum hloov cov khoom pellets rau hauv homogeneous molten polymer thiab xa cov yaj ntawd los ntawm kev tuag ntawm tus nqi ruaj khov.

Rau ib qho -txheej HDPE yeeb nkab, tsis muaj txheej txheej ntxiv los them rau cov khoom tawg tsis zoo. Tag nrho cov yeeb nkab phab ntsa los ntawm ib qho txuas ntxiv polymer yaj. Txhua yam tsis ruaj khov hauv plasticization, yaj kub, siab, lossis extrusion tso zis tuaj yeem tshwm sim tom qab qhov sib txawv ntawm qhov sib txawv, qhov tsis xws luag, tsis sib xws ntawm phab ntsa thickness, lossis tsis ruaj khov ntau lawm.

Kev nkag siab txog theem no pab piav qhia vim li cas extrusion tsis yog ib qho teeb meem ntawm cov yas yas thiab thawb nws los ntawm kev tuag.

1. Los ntawm HDPE Pellets mus rau ib qho kev sib txuas txuas ntxiv

HDPE pellets nkag mus rau hauv extruder los ntawm lub hopper thiab maj mam thauj mus rau pem hauv ntej los ntawm cov ntsia hlau tig.

Cov ntsia hlau feem ntau ua ntau yam haujlwm thaum lub sijhawm txav no. Nws xa cov khoom siv, hloov cov cua sov rau hauv cov polymer, tsim cov cua sov ntxiv, yaj cov khoom, sib tov cov yaj, thiab thaum kawg tsim kom txaus siab rau cov tuag.

Cov khoom yog li ntawd dhau los ntawm lub cev sib txawv thaum lub sij hawm extrusion:

Qhov zoo ntawm cov yeeb nkab zaum kawg yog nyob ntawm ntau npaum li cas cov kev hloov pauv no tshwm sim.

Yog tias ib feem ntawm cov polymer tseem yaj tsis txaus, cov yaj tuaj yeem ua tsis yog -uniform. Yog hais tias lub melting kub kub dhau heev lawm, thermal degradation yuav ua rau muaj kev txhawj xeeb. Yog hais tias lub yaj tsis txaus homogeneous, qhov ntev stability kuj yuav nyuaj rau tswj.

2. Ntsia Hlau Ceev thiab Extrusion Output

Extrusion tso zis yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws nyob rau hauv ib qho - txheej yeeb nkab ntau lawm.

Kev nrawm nrawm feem ntau nce cov khoom siv, tab sis kev sib raug zoo tsis yog "kev nrawm dua sib npaug ntau dua." Khoom noj khoom noj zoo, yaj kub, ntsia hlau geometry, rov qab siab, thiab polymer rheology tag nrho cuam tshuam rau qhov tseeb tso zis.

Rau cov yeeb nkab extrusion kab, kev sib raug zoo ntawm cov khoom tso tawm thiab thauj - tawm ceev yog qhov tseem ceeb tshwj xeeb.

Yog hais tias lub extruder muab ntau yaj thaum lub thauj -off ceev tseem tsis hloov, cov khoom ntau yog muab tso rau hauv cov yeeb nkab phab ntsa.

Yog hais tias lub thauj - tawm ceev nce thaum extrusion tso zis tseem nyob tas li, cov khoom tsawg dua raug faib rau ib chav tsev ntev.

Qhov kev sib cuam tshuam ncaj qha cuam tshuam rau qhov kawg qhov ntev.

Cov txheej txheem extrusion yog li yuav tsum muaj kev sib npaug ruaj khov ntawm:

Cov ntaub ntawv hla dhau → Melt Flow → Pipe Formation → Haul -Off

Qhov no yog ib qho laj thawj vim li cas tsis ruaj khov extrusion tso tawm tuaj yeem tsim qhov ntev ntawm qhov sib txawv txawm tias thaum lub tshuab nominal teeb pom kev hloov pauv.

3. Qhov kub thiab txias yog ntau tshaj qhov cua sov

HDPE tsis yaj ntawm ib qho kub ib yam li qhov qis - kua viscosity tsuas yog boil los yog khov ntawm ib qho chaw ruaj khov.

Lub polymer tau hloov pauv los ntawm cov khoom siv mus rau hauv lub xeev viscous molten. Qhov tseeb yaj yog nyob ntawm qib resin, qauv molecular, shear keeb kwm, lub sij hawm nyob, thiab thermal zog qhia los ntawm extruder.

Lub thoob tso cua sov muab cov cua sov sab nraud, tab sis cov ntsia hlau tig kuj ua rau lub zog siv hluav taws xob uas hloov mus rau hauv cov cua sov.

Yog li ntawd, qhov ntsuas kub ntawm qhov tso tawm tsis tas yuav tsum zoo ib yam li qhov ntsuas kub ntawm cov yaj nkag mus rau qhov tuag.

Rau kev tswj kev tsim khoom, cov yaj yuav tsum tau ua kom muaj plasticized txaus thiab homogeneous yam tsis muaj thermal raug ntau dhau.

Qhov nyiaj tshuav no dhau los ua qhov tseem ceeb tshwj xeeb rau cov kav dej loj dua - txoj kab uas hla vim tias cov khoom xav tau dhau los tuaj yeem siab dua.

4. Melt Pressure thiab Flow Stability

Ua ntej cov yaj mus txog qhov tuag, nws yuav tsum tsim kom muaj siab txaus kom dhau los ntawm cov dej ntws.

Melt siab yog qhov tseem ceeb raws li tus txheej txheem qhia vim tias qhov kev hloov siab tam sim ntawd tuaj yeem qhia txog kev hloov pauv ntawm cov khoom noj, yaj viscosity, kub, pom, lossis tuag tsis kam.

Lub kaw lus ruaj khov extrusion feem ntau ua rau cov kua nplaum ruaj khov nyob rau hauv kev ua haujlwm ruaj khov.

Kev hloov pauv yaj siab tuaj yeem ua rau cov zis tsis ruaj khov. Cov txiaj ntsig yuav tsis tshwm sim tam sim ntawm qhov tuag, tab sis qhov sib txawv ntawm qhov sib txawv tuaj yeem pom pom ntxiv mus rau hauv qab.

Vim li no, extrusion siab yuav tsum tsis txhob suav hais tias tsuas yog lub tshuab parameter. Nws kuj yog ib qho qhia txog kev ruaj ntseg ntawm cov polymer ntws nkag mus rau theem tsim.

5. Die Flow txiav txim qhov pib Geometry

Tom qab plasticization thiab homogenization, cov yaj nkag mus rau hauv lub annular tuag.

Cov tuag hloov cov khoom ntws los ntawm extruder mus rau hauv daim ntawv tubular.

Lub sijhawm no, cov yeeb nkab tseem tsis tau muaj nws qhov kawg qhov ntev. Cov polymer kub tseem deformable, thiab nws qhov ntev tuaj yeem hloov pauv thaum nws tawm hauv qhov tuag.

Ib qho tshwm sim tseem ceeb yogtuag swell.

Vim tias HDPE yog viscoelastic polymer, ib feem ntawm qhov deformation yuam hauv qhov tuag tuaj yeem rov qab tau tom qab cov yaj tawm ntawm qhov tuag. Cov extrudate tej zaum yuav yog li nthuav txheeb ze rau qhov qhib tuag.

Tus nqi ntawm cov tuag swell nyob ntawm yam xws li kub kub, shear npaum li cas, polymer rheology, tuag geometry, thiab extrusion tej yam kev mob.

Qhov no yog ib qho laj thawj vim li cas qhov tuag tsis tuaj yeem tsuas yog tsim los rau qhov kawg sab nraud txoj kab uas hla ntawm cov yeeb nkab.

Cov txheej txheem downstream sizing yog lub luag hauj lwm los tsim kom tau qhov kawg dimensional geometry.

6. Vim li cas Stable Extrusion Matters rau Mining HDPE Yeeb Nkab

Rau cov ntawv thov dej mine, qhov sib npaug ntawm qhov tseem ceeb vim tias cov kav dej feem ntau teev los ntawm nominal txoj kab uas hla, phab ntsa thickness, SDR thiab chav kawm siab.

Xav txog ob qhov sib txawv SDR11 qhov ntev:

Kev suav yog ncaj nraim:

Phab ntsa Thickness=Sab nraud Diameter ÷ SDR

Txawm li cas los xij, kev tsim cov yeeb nkab ze rau qhov theoretical ratio yuav tsum ruaj khov extrusion thiab downstream dimensional control.

Ib qho me me instability nyob rau hauv yaj tso zis yuav ua tau ntau yam tseem ceeb thaum ua ke nrog siab ntau lawm ceev los yog loj yeeb nkab qhov ntev.

7. Extrusion Variables uas tsim nyog mloog

Rau ib qho - txheej HDPE yeeb nkab extrusion, cov kev hloov pauv tseem ceeb tuaj yeem ua tiav raws li hauv qab no:

Cov kev hloov pauv no muaj kev sib tshuam.

Hloov ib qho chaw tuaj yeem cuam tshuam rau lwm qhov. Piv txwv li, kev tsim cov khoom tsim tawm tuaj yeem hloov pauv lub siab thiab qhov kub thiab txias, thaum hloov cov tsheb thauj mus los -off ceev tuaj yeem cuam tshuam qhov tshwm sim qhov ntev txawm tias cov khoom siv extrusion tseem tsis hloov.

8. Yuav ua li cas thaum Extrusion tsis ruaj khov?

Cov txheej txheem extrusion tsis ruaj khov tuaj yeem tsim ntau cov tsos mob hauv qab.

Cov yeeb nkab tuaj yeem pom qhov ntev ntawm qhov sib txawv. Qhov saum npoo tuaj yeem ua tsis sib xws. Phab ntsa thickness tswj yuav nyuaj dua. Lub downstream sizing system kuj yuav tau them nyiaj rau qhov kev hloov pauv tsis tu ncua.

Qhov no yog vim li cas extrusion stability yog lub hauv paus es tsis yog qhov kawg seem - tswj theem.

Lub tshuab nqus tsev sizing tuaj yeem tsim kom muaj txoj kab nruab nrab sab nraud, tab sis nws tsis tuaj yeem tshem tawm cov khoom tawg tsis ruaj khov.
