EVA Sheet Tshuab Kab

Eva (Ethylene Vinyl acetate Copolymer) daim ntawv yog cov khoom siv khau, khoom siv hluav taws xob, kev ua si, hloov kho cov tshuaj, thiab kev ua haujlwm zoo.

 

Lub ntsiab ntawm kev tsim cov ntawv E VAFs yog extrusion molding, thiab cov khoom siv sib xws yog EVA ntawv extrusion kab. Cov kab ntau lawm tau zoo sib xws nrog cov kab ntawv PP / PE daim ntawv uas tau hais tawm ntxov, thiab qhov ua tau zoo nkauj, thiab cov khoom siv kuj muaj nws cov nta.

 

 

Ua tiav EVA ntawv tshuab kab feem ntau muaj cov ntu hauv qab no:

1. Cov Khoom Siv Khoom Ua Haujlwm

LOMIC FAIV NEEG: Cov ntaub ntawv eva raw feem ntau yog nyob rau hauv daim ntawv granular. Yog tias tsim cov ntawv sau ua yeeb yam, nws yog ib qho tsim nyog yuav tsum tau muab cov tshuaj tiv thaiv foaming (xws li AC foaming cov neeg sawv cev) thiab lwm yam kev sib ntxiv (crosslinking cov neeg sawv cev, cov roj nplua nyeem, thiab lwm yam).

Yehixyau · Ehixyau:

· Tsis siv neeg pub mis tshuab: Thauj Eva hais los ntawm silo rau extruder hopper.

· Kev pub mis cov txheej txheem: Qhov no yog cov khoom siv tseem ceeb rau kev tsim cov ntawv ua npuas ncauj. Feem ntau, qhov hnyav ntsuas ntsuas ntsuas yog siv los ua kev sib npaug ntawm cov qauv sib npaug ntawm cov qauv ua haujlwm, cov xim ua npuas ncauj kom tau txais cov khoom ua kom zoo nkauj ua kom zoo.

 

2. Extruder

· Ua kom tiav: yaj, yas yas, thiab tusyees sib xyaw ntawm Evas cov khoom siv. Rau cov ntaub ntawv ua npuas ncauj, nws tseem tsim nyog rau tusyees disperse tus neeg sawv cev foaming hauv cov yaj.

Typha:

Tus Extruder: Extrude Extruder: Tsim nyog rau kev tsim cov khoom siv tsis muaj kev ua kom zoo nkauj lossis cov qauv ua npuas thiab cov nqi yooj yim thiab tus nqi qis.

· Partalel thiab sib tw Twin -} ntsia hlau extruder: ib qho kev xaiv zoo dua thiab muaj txiaj ntsig zoo. Nws cov kev sib xyaw ua tau zoo heev, uas tuaj yeem hloov kho cov ua npuas ncauj thiab cov pigments, kom ntseeg tau tias nws muaj zog ruaj khov. Tshwj xeeb tshaj yog haum rau kev sau siab thiab ua npuas dej EVA.

 

3. Network Changer

· Muaj nuj nqi: Lim impenities thiab tsis muaj cov khoom siv tsis tau muaj nyob rau hauv cov melt, tiv thaiv cov pwm pulity, thiab ua kom cov khoom siv huv thiab cov khoom lag luam zoo. Feem ntau, nws yog lub hydraulic tsis siv neeg screen cabger uas tuaj yeem hloov lub lim screen tsis tas yuav tsum nres lub tshuab, ua kom tiav ntau lawm.

 

4. Mould

LOM QAB: Sharmed lub extruded molten yas rau hauv qhov xav tau dav thiab tuab.

· Type: Feem ntau yog siv tus Khuam Kanger ntaus lub taub hau tiaj tus tub, nws tau faib cov ntawv dav dav, yog li tau txais cov ntawv sau nrog tuab tuab.

· DACE: Cov pwm puab feem ntau los nrog kev nplua- hloov tau qhov sib txawv ntawm cov haujlwm sib txawv los tswj cov ntawv tuab.

 

5. Peb Roll Cegender

· Ua Haujlwm: Qhov no yog cov khoom siv tseem ceeb hauv EVA daim ntawv ntau lawm.

· Txias thiab shaping: lub siab {{0} kub}

· Txiav tawm cov nyhuv tuab thiab cov nyhuv npoo av thiab gloss los yog txiav txim siab los ntawm kev sib txawv ntawm peb chais thiab lub ntsej muag du ntawm cov chais.

· DACE: Peb cov zaub tuaj yeem hloov kho qhov nrawm thiab kub kom tau raws cov txheej txheem sib txawv.

 

6. Cov chav tsev

LOM ZAUM: Coj ncaj qha rau cov ntawv txias thiab cov ntawv nyeem ntawm cov khoom winding.

· Muaj tshuaj: Feem ntau muaj ntawm ib lossis ntau khub ntawm cov roj hmab lossis silicone chais, muab cov kev sib txuam thiab tiv thaiv kev tawm tsam.

 

7. Cov khoom siv online kuaj xyuas (yeem tab sis tseem ceeb)

Betha Ray lossis Retrared Thoockness Thermness ntsuas: lub sijhawm ntsuas phoo thiab muab cov lus sib txuas ntawm cov ntaub ntawv hloov chaw ntawm cov ntaub ntawv kom ua tiav cov ntaub ntawv tsis siv neeg (ATC), txhim kho kom zoo sib xws.

 

8. Cua

Thaum ua haujlwm: Yob daim ntawv rau hauv cov qauv yob. Vim kev softness ntawm EVA cov ntawv txheeb, tswj cov winding winding yog qhov tseem ceeb heev.

Typha:

· Lub tshuab cua tshuab hluav taws xob: winding cua los ntawm tsav lub tub ntxhais kom tig, haum rau ntau qhov kev qhia tshwj xeeb.

Ist Deg tshuab winding: Nws yog ib qho kev siv winding rau EVA cov ntawv txheeb.

· The {-}}} Cov khoom siv kawg tau rov qab ua dua tshiab tsis nres lub tshuab, ua tiav tsis siv neeg tsis siv neeg ntau lawm.

 

9. Hluav taws xob tswj hwm

Bicte aun: 'Hlwb Hlwb' ntawm Kab Ntau Lawm. Txais cov PLC tswj thiab muab cov txheej txheem kov, txhua cov txheej txheem tsis xws li kub, cov qhob ntsia hlau ceev, tracting nro ntawm txhua ntu tuaj yeem yog teeb tsa thiab tswj tau.

Cov yam ntxwv ua npuas ncauj sau cov ntaub ntawv EVA ntawv EVA cov khoom siv

Tus raw khoom siv cov khoom siv yuav tsum tau nruab nrog high - precision ceeb thawj poob ntsuas ntsuas cov npuas dej. Ib lub tshuab pub mis noj mov tuaj yeem ua tau raws li qhov yuav tsum tau ua.

Tus Extruder muaj cov kev xav tau siab heev rau cov kev sib xyaw ua ke thiab tawg paj lug ntawm cov ntsia hlau, thiab ntxaib {{0} ntsia hlau ib yam yog nyiam. Tib lub hau ntswj lossis ntxaib ntsia hlau tuaj yeem siv.

Cov txheej txheem tswj yuav tsum muaj qhov tseeb dua. Tswj kub ncaj qha cuam tshuam rau cov foaming piv thiab cov qauv cell. Kuj yooj yim.

Cov qauv pwm zoo ib yam, tab sis tus qauv tsim nyog xav tau xav txog cov fluidity ntawm cov melt muaj cov ua npuas ncauj. Txheem hau txaj muag style taub hau taub hau.

Cov cuab yeej tom ntej, peb lub yob taws, yog qhov tseem ceeb rau kev tswj kom tuab thiab nto ntawm cov ntawv ua npuas ncauj. Yuav tsum muaj peb lub Coll Civ qab yog yuav tsum tau ua.

 

 

1. Cov Khoom Qhia: Qhia meej seb lub ntsiab ntau lawm yog ua npuas ncauj lossis tsis ua npuas ncauj nplooj ntawv? Dab tsi yog foaming piv? Qhov no ncaj qha txiav txim siab cov kev xaiv ntawm extruders thiab pub mis.

2. Cov Khoom Siv Khoom Muag: Qhov siab tshaj plaws qhov dav (xws li 1000mm, 1300mm, 1500mm, thiab lwm yam) thiab ntau dua 0.5mm-10mm).

3. Qeb theem: Koj puas xav tau kev pub siv hluav taws xob pub ntxiv, tsis siv neeg ntxaij hloov, ATCNANNESS cov lus qhia (ATC), thiab tsis siv neeg winding? Cov no tuaj yeem txhim kho cov khoom lag luam zoo thiab ruaj khov, tab sis kuj tseem nce nqi.

4. Kev tsim cov khoom lag luam: txiav txim qhov loj me ntawm Extruder Model (ntsia hlau txoj kab no).

5. Cov Chaw Muag Khoom Xaiv: Kev coj Yu Yuav tsum muaj cov txheej txheem kev paub qib siab. Cov Khoom Siv Khoom Siv Khoom Siv nrog cov txheej txheem thev naus laus zis, muaj peev xwm muab cov kev taw qhia hauv cov qauv, kev teeb tsa thiab kev cob qhia ua haujlwm, thiab kev kawm ua haujlwm yuav tsum raug xaiv.

Ntsiab lus: EVA ntawv cov khoom siv yog cov thev naus laus zis extrusion cov kab ntau lawm, tab sis nws cov kev teeb tsa tseem txawv nyob ntawm kev tsim cov foamed lossis tsis muaj cov khoom lag luam. Cov tub ntxhais nyob hauv cov khoom thauj khoom nyoos sib piv, ua tau zoo me ntsis sib xyaw, thiab ua kom muaj cua txias. Ua ntej nqis peev, nws yog qhov tseem ceeb kom sib txuas lus tag nrho koj cov khoom xav tau nrog cov khoom siv khoom siv.
