Dab tsi yog Stretch Film Wrap Ua Los Ntawm

Cov khoom siv tseem ceeb: Polyethylene (PE)

Ntawm nws cov theem pib, stretch zaj duab xis feem ntau yog tsim los ntawmpolyethylene (PE), ib qho thermoplastic polymer muab tau los ntawm roj av lossis cov nkev ntuj. Polyethylene yog cov yas tsim ntau tshaj plaws hauv ntiaj teb, suav txog kwv yees li ib -feem peb ntawm tag nrho cov khoom yas. Hom tshwj xeeb ntawm polyethylene siv nyob rau hauv stretch film manufacturing yoglinear low -density polyethylene (LLDPE), uas muab cov stretchability zoo, lub zog, thiab clarity.

Vim li cas LLDPE?

LLDPE yog cov khoom ntawm kev xaiv rau stretch film vim nws cov qauv molecular tshwj xeeb. Tsis zoo li cov pa qis- ntom ntom polyethylene (LDPE), LLDPE muaj cov saw hlau uas muaj cov ceg luv luv. Cov qauv no tso cai rau cov khoom siv kom ncav cuag (txog li 300% lossis ntau dua) yam tsis muaj kev tawg, thaum tswj kev ua haujlwm zoo heev thiab lub zog tsim kua muag.

Cov txheej txheem tsim khoom: Los ntawm resin rau zaj duab xis

Txoj kev taug kev los ntawm cov khoom siv raw mus rau qhov ua tiav stretch zaj duab xis suav nrog ntau cov txheej txheem tsim khoom:

1. Polymerization

Cov txheej txheem pib nrog ethylene gas, uas yog muab los ntawm cov roj crude los yog natural gas los ntawm tus txheej txheem hu ua cracking. Nyob rau hauv lub xub ntiag ntawm catalysts thiab nyob rau hauv tshwj xeeb kub thiab siab tej yam kev mob, ethylene molecules bonds ua ke los tsim polyethylene chains. Rau LLDPE, qhov polymerization no tshwm sim siv cov pa roj-theem lossis kev daws teeb meem- theem txheej txheem.

2. Kev sib xyaw ua ke thiab kev sib xyaw ntxiv

Lub hauv paus LLDPE resin yog tom qab sib xyaw nrog ntau yam tshuaj ntxiv los txhim kho cov yeeb yaj kiab kev ua tau zoo. Cov additives no muaj xws li:

Slip tus neeg sawv cev: Txo kev sib txhuam ntawm cov txheej txheem zaj duab xis, ua kom yooj yim rau unwind thiab thov

Anti-tus neeg saib xyuas: Tiv thaiv cov khaubncaws sab nraud povtseg ntawm zaj duab xis los ua ke thaum lub sijhawm khaws cia

UV stabilizers: Tiv thaiv zaj duab xis los ntawm degradation thaum raug tshav ntuj

Antistatic tus neeg sawv cev: Txo cov hluav taws xob zoo li qub

Cov xim: Rau cov yeeb yaj kiab xim (txawm tias feem ntau cov yeeb yaj kiab yog qhov tseeb)

Tackifiers: Ua kom cov khoom sib txuas kom ruaj khov dua

3. Extrusion

Lub compounded resin yog yaj thiab yuam los ntawm ib ncig tuag los tsim ib tug nyias, nruam raj ntawm molten yas. Cov txheej txheem no, hu ua cua tshuab extrusion, tso cai rau kev tswj xyuas meej ntawm zaj duab xis thickness thiab cov khoom.

4. Stretching thiab Orientation

Lub molten zaj duab xis yog ces stretched nyob rau hauv ob qho tib si lub tshuab kev taw qhia (MD) thiab transverse kev taw qhia (TD) mus dlhos lub polymer molecules. Cov txheej txheem kev taw qhia no txhim kho cov zaj duab xis lub zog, clarity, thiab stretch zog. Lub℃ntawm stretching txiav txim seb cov zaj duab xis yuav cam khwb cia los yog tshuab.

5. Cua txias thiab cua txias

Thaum kawg, cov zaj duab xis stretched yog txias, trimmed mus rau qhov xav tau dav, thiab lub qhov txhab mus rau cores los tsim cov tiav rolls ntawm stretch zaj duab xis.

Hom Stretch Zaj duab xis Raws li Kev Tsim Khoom

Cast Stretch Zaj duab xis

Cam khwb cia stretch zaj duab xis yog tsim los siv cov txheej txheem uas cov yas molten yog extruded los ntawm ib tug ca tuag mus rau ib tug chilled roller. Txoj kev no tsim cov yeeb yaj kiab nrog:

Cam khwb cia zaj duab xis yog qhov zoo tagnrho rau cov ntawv thov uas qhov khoom pom tau yog qhov tseem ceeb, xws li cov khw muag khoom muag lossis thaum cov barcodes yuav tsum tau luam tawm los ntawm qhwv.

Blown Stretch Zaj duab xis

Blown stretch zaj duab xis yog tsim los ntawm extruding cov yas molten los ntawm lub voj voog tuag thiab inflating nws zoo li lub zais pa. Qhov no tsim ib npuas uas tom qab ntawd tawg thiab raug mob. Blown film muaj:

Superior zog thiab tsim kua muag kuj

Nco zoo dua (muaj peev xwm rov qab mus rau nws qhov qub qub)

Ntau dua load- tuav quab yuam

Kev zam txim ntau dua (tuaj yeem ncab ntau yam tsis muaj kev tawg)

Blown zaj duab xis feem ntau yog siv rau qhov hnyav dua lossis tsis xwm yeem zoo li cov loads uas yuav tsum tau muaj kev tiv thaiv ntau tshaj.

Cov khoom qib thiab cov yam ntxwv ua haujlwm

Standard Qib
