Dab tsi Raw Materials Yuav Tsum Tau rau Lub Tshuab Txiv Hmab Txiv Ntoo?

Yog tias koj tab tom ntsuas lub tshuab txiv hmab txiv ntoo rau koj lub lag luam ntim hauv xyoo 2026, kev nkag siab nws cov ntaub ntawv raw yog ib qho tseem ceeb raws li kev paub txog tus nqi tshuab. Lub tshuab txiv hmab txiv ntoo feem ntau ua cov txheej txheem polyethylene-raws li cov resins rau hauv cov mos mos, stretchable tubular mesh tes tsho uas tiv thaiv cov txiv hmab txiv ntoo xws li txiv apples, pears, txiv duaj, thiab citrus thaum thauj thiab khaws cia. Kev xaiv cov khoom raug raug cuam tshuam ncaj qha rau cov khoom zoo, kev ruaj ntseg ntau lawm, thiab ib tus nqi -meter.

Primary Raw Khoom: LDPE

Cov khoom tseem ceeb rau yuav luag tag nrho cov txiv hmab txiv ntoo net ua haujlwm yog Tsawg-Density Polyethylene (LDPE) . LDPE muaj qhov zoo tshaj plaws melt flow index (feem ntau MFI 1.5–4.0 g / 10min), yooj, thiab softness yuav tsum tau rau txiv hmab txiv ntoo net extrusion. Nws feem ntau yog pub rau hauv daim ntawv nkauj xwb pellet, txawm hais tias qee tus neeg ua haujlwm sib xyaw 10-30% rov ua dua LDPE granules los txo tus nqi yam tsis muaj kev cuam tshuam net elasticity. Qib LDPE yuav tsum tau tsim tshwj xeeb rau foaming lossis net extrusion - dav dav -hom phiaj txhaj tshuaj{11}} qib LDPE yuav tsis tsim cov qauv mesh zoo ib yam.

Secondary Raw Khoom: EPE Resin

Ntau cov txiv hmab txiv ntoo niaj hnub siv tshuab siv Expandable Polyethylene (EPE) resin es tsis yog tus qauv LDPE. EPE muaj cov tshuab tshuab lub cev ua ntej- tawg mus rau hauv cov pellets. Thaum rhuab hauv lub extruder chim, tus neeg sawv cev tshuab expands, tsim cov yam ntxwv ua npuas ncauj kev ntxhib los mos uas muab cov txiv hmab txiv ntoo nets lawv cushioning zog. Ntshiab EPE resin raug nqi ntau dua ib kilogram dua li LDPE dawb tab sis tshem tawm qhov xav tau ntawm cov tshuaj ua npuas ncauj cais, ua kom yooj yim tswj cov txheej txheem, thiab tsim cov nets softer.

Additives thiab Auxiliary Materials

Peb hom additives feem ntau pub nrog rau lub ntsiab cob rau hauv lub tshuab txiv hmab txiv ntoo:

Foaming Agent​​ - Yog tias siv cov LDPE dawb es tsis txhob ua ntej - nthuav EPE resin, cov tshuaj foaming agent (feem ntau azodicarbonamide-raws li lossis endothermic foaming masterbatch) yuav tsum tau ntxiv ntawm 1-3% los ntawm qhov hnyav. Tus neeg sawv cev no decomposes ntawm extrusion kub los tsim cov pa npuas nyob rau hauv lub molten polymer, tsim cov cellular ua npuas ncauj qauv.

Xim Masterbatch - Cov txiv hmab txiv ntoo nets feem ntau muaj xim rau kev ua lag luam lossis kev txheeb xyuas lub hom phiaj. Txheem xim masterbatch (PE cab kuj raws li) yog ntxiv ntawm 2-5% piv. Cov xim muaj xws li ntsuab, liab, daj, txiv kab ntxwv, thiab dawb.

Anti-Static Agent / Slip Additive​ - Xaiv tau tab sis pom zoo thaum cov nets raug mob rau yob rau lub tshuab tes tsho uas siv tau. Cov additives tiv thaiv zoo li qub cling thiab txo qhov kev sib txhuam ntawm qhov chaw kom cov tes tsho nyias nyias nyias.

Cov khoom siv ntxiv

Tshaj li ntawm polymer nws tus kheej, lub tshuab txiv hmab txiv ntoo yuav tsum:

Cov dej txias rau lub nplhaib sizing thiab txias trough (kaw- voj voj voog yog tus qauv).

Compressed cua rau npuas inflation nyob rau hauv lub net tube.

Txiav hniav (hloov tau) rau lub tshuab txiav tsis siv neeg.

Winding cores (cov duab los qhia lossis cov yas yas) rau cov yob tiav.

Yam Khoom Noj Khoom Haus

Ib qho nruab nrab - tso tawm txiv hmab txiv ntoo net tshuab ua 10-20 kg / teev ntawm cov khoom tiav tiav siv kwv yees li:

92-96% LDPE lossis EPE resin

2-4% foaming masterbatch (yog siv LDPE dawb)

2-5% xim masterbatch

<1% other additives

Tag nrho cov khoom siv raw cov nqi feem ntau suav txog 55-70% ntawm tus nqi muag khoom kawg, ua cov khoom siv cob qhia yog qhov tseem ceeb hauv kev muaj txiaj ntsig.

Hauv cov ntsiab lus, cov ntaub ntawv raw khoom tseem ceeb rau txhua lub tshuab txiv hmab txiv ntoo yog LDPE lossis EPE resin ua lub hauv paus polymer, tus neeg sawv cev foaming yog tias xav tau, xim masterbatch rau kev pom kev sib txawv, thiab cov khoom siv me me. Cov neeg ua haujlwm yuav tsum sim cov khoom siv sib raug zoo nrog lawv cov txiv hmab txiv ntoo tshwj xeeb net tshuab ntsia hlau tsim thiab qhov kub thiab txias ua ntej cog lus rau kev yuav khoom ntau.
