1.PE Stretch Zaj duab xis txhais
PE stretch zaj duab xis (tseem hu ua stretch wrap) yog ib zaj duab xis yas uas muaj cov nplaum rau nws tus kheej uas tuaj yeem ncab thiab nruj nreem qhwv ib ncig ntawm cov khoom, ob sab ntawm ib sab (extrusion) lossis ob sab (tshuab).Cov nplaum tsis ua raws li qhov chaw ntawm cov khoom, tab sis tseem nyob rau ntawm zaj duab xis nto.Nws tsis tas yuav tsum muaj cua sov shrinking thaum lub sij hawm ntim cov txheej txheem, uas yuav pab txuag hluav taws xob, txo cov nqi ntim, ua kom yooj yim thauj cov thawv, thiab txhim kho logistics efficiency.Kev sib xyaw ua ke ntawm pallets thiab forklifts txo cov nqi tsheb thauj mus los, thiab cov pob tshab siab ua kom yooj yim rau kev txheeb xyuas cov khoom, txo cov khoom tsis raug.
Specifications: Tshuab zaj duab xis dav 500mm, phau ntawv zaj duab xis dav 300mm, 350mm, 450mm, 500mm, thickness 15um-50um, yuav slit rau ntau yam specifications.
2.Classification ntawm PE Stretch Film Siv
(1) Phau ntawv Stretch Film:Txoj kev no tsuas yog siv phau ntawv ntim, thiab phau ntawv stretch zaj duab xis feem ntau muaj qis dua qhov yuav tsum tau ua.Txhua yob hnyav ib ncig ntawm 4kg lossis 5kg rau kev ua haujlwm yooj yim.
(2) Tshuab Stretch Zaj duab xis:Tshuab stretch zaj duab xis yog siv rau txhua yam ntim, feem ntau yog tsav los ntawm kev txav ntawm cov khoom kom ua tiav ntim.Nws yuav tsum muaj zog tensile ntau dua thiab stretchability ntawm zaj duab xis.
Qhov dav dav dav yog 300%, thiab yob hnyav yog 15kg.
(3) Tshuab Pre-stretch Zaj duab xis:Hom stretch zaj duab xis no tsuas yog siv rau cov khoom ntim khoom.Thaum lub sij hawm ntim, lub tshuab ntim thawj zaug nthuav cov zaj duab xis rau ib qho piv txwv thiab tom qab ntawd qhwv nws ib ncig ntawm cov khoom yuav ntim.Nws cia siab rau zaj duab xis elasticity kom compactly ntim cov khoom.Cov khoom muaj lub zog tensile siab, elongation, thiab puncture kuj.
(4) Xim Zaj duab xis:Coloured stretch films muaj nyob rau hauv xiav, liab, daj, ntsuab, thiab dub.Cov neeg tsim khoom siv lawv los ntim cov khoom thaum sib txawv ntawm cov khoom sib txawv, ua kom yooj yim rau kev txheeb xyuas cov khoom.
3.Control ntawm PE Stretch Film Adhesiveness
Zoo adhesiveness xyuas kom meej tias cov txheej txheej ntawm ntim zaj duab xis adhered rau ib leeg, muab kev tiv thaiv nto rau cov khoom thiab tsim ib tug sib sib zog nqus tiv thaiv txheej nyob ib ncig ntawm cov khoom.Qhov no pab tiv thaiv plua plav, roj, noo noo, dej, thiab tub sab.Qhov tseem ceeb, stretch film ntim tusyees faib quab yuam nyob ib ncig ntawm cov khoom ntim, tiv thaiv kev ntxhov siab tsis sib xws uas tuaj yeem ua rau cov khoom puas tsuaj, uas tsis tuaj yeem ua tiav nrog cov txheej txheem ntim khoom xws li strapping, bundling, thiab daim kab xev.
Cov txheej txheem kom ua tiav cov nplaum feem ntau suav nrog ob hom: ib qho yog ntxiv PIB lossis nws cov khoom siv rau cov khoom siv polymer, thiab lwm qhov yog sib xyaw nrog VLDPE.
(1) PIB is a semi-transparent, viscous liquid.Kev sib ntxiv ncaj qha yuav tsum tau siv cov cuab yeej tshwj xeeb lossis hloov kho cov cuab yeej.Feem ntau, PIB masterbatch yog siv.PIB muaj cov txheej txheem tsiv teb tsaws, uas feem ntau siv peb hnub, thiab tseem cuam tshuam los ntawm qhov kub thiab txias.Nws muaj zog adhesiveness ntawm qhov kub thiab txias thiab tsawg adhesiveness ntawm qhov kub thiab txias.Tom qab ncab, nws adhesiveness txo qis heev.Yog li ntawd, cov zaj duab xis tiav yog qhov zoo tshaj plaws khaws cia nyob rau hauv ib tug tej yam kub thiab txias (pom zoo cia kub: 15 ° C mus rau 25 ° C).
(2) Kev sib xyaw nrog VLDPE muaj qhov nplaum me ntsis tab sis tsis xav tau cov cuab yeej tshwj xeeb.Adhesiveness yog qhov ruaj khov, tsis raug rau lub sijhawm txwv, tab sis kuj cuam tshuam los ntawm qhov kub thiab txias.Nws yog cov nplaum nplaum ntawm qhov kub siab tshaj 30 ° C thiab tsawg dua nplaum ntawm qhov kub hauv qab 15 ° C.Kho tus nqi ntawm LLDPE hauv cov nplaum txheej tuaj yeem ua tiav qhov xav tau viscosity.Txoj kev no feem ntau yog siv rau peb-txheej co-extrusion films.
4.Cov yam ntxwv ntawm PE Stretch Film
(1) Kev sib koom ua ke: Qhov no yog ib qho ntawm cov yam ntxwv loj tshaj plaws ntawm kev ntim zaj duab xis, uas nruj nreem khi cov khoom rau hauv ib qho kev cog lus, ruaj khov, txawm tias nyob rau hauv cov xwm txheej tsis zoo, tiv thaiv kev xoob lossis sib cais ntawm cov khoom.Lub ntim tsis muaj cov npoo ntse lossis nplaum, yog li zam kev puas tsuaj.
(2) Kev Tiv Thaiv Thawj: Kev tiv thaiv thawj zaug muab kev tiv thaiv nto rau cov khoom, tsim kom muaj kev tiv thaiv sab nrauv.Nws tiv thaiv plua plav, roj, noo noo, dej, thiab tub sab.Stretch zaj duab xis ntim tusyees faib quab yuam nyob ib ncig ntawm cov khoom ntim, tiv thaiv kev txav thiab txav mus los thaum thauj, tshwj xeeb tshaj yog nyob rau hauv kev lag luam luam yeeb thiab textile, qhov twg nws muaj qhov tshwj xeeb ntim cov teebmeem.
(3) Txuag Nqi: Siv cov zaj duab xis ncab rau cov khoom ntim tuaj yeem txo cov nqi siv tau zoo.Stretch zaj duab xis tsuas yog siv li ntawm 15% ntawm thawj lub thawv ntim, txog 35% ntawm cov yeeb yaj kiab tshav kub, thiab li 50% ntawm cov thawv ntim khoom.Nws kuj tseem txo qis kev siv zog, txhim kho kev ntim khoom, thiab txhim kho qib ntim.
Nyob rau hauv cov ntsiab lus, daim ntawv thov teb ntawm stretch zaj duab xis yog dav heev, nrog rau ntau qhov chaw hauv Suav teb tseem tsis tau tshawb nrhiav, thiab ntau qhov chaw uas tau tshawb fawb tseem tsis tau siv dav.Raws li daim ntawv thov teb nthuav dav, kev siv cov yeeb yaj kiab stretch yuav nce ntxiv, thiab nws txoj kev lag luam muaj peev xwm ua tsis tau.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum muaj zog txhawb kev tsim khoom thiab siv cov yeeb yaj kiab stretch.
5.Kev siv ntawm PE Stretch Film
PE stretch zaj duab xis muaj lub zog tensile siab, tsim kua muag tsis kam, pob tshab, thiab cov khoom zoo rov qab.Nrog rau qhov sib piv ua ntej ntawm 400%, nws tuaj yeem siv rau kev ntim khoom, kev tiv thaiv dej, plua plav pov thawj, tiv thaiv tawg, thiab tiv thaiv tub sab lub hom phiaj.
Kev Siv: Nws yog siv rau pallet wrapping thiab lwm yam ntim ntim thiab yog siv dav hauv kev lag luam tawm txawv teb chaws, lub raj mis thiab tuaj yeem tsim, ntawv ua, kho vajtse thiab khoom siv hluav taws xob, yas, tshuaj, khoom siv hauv tsev, khoom siv ua liaj ua teb, zaub mov, thiab lwm yam lag luam. .
