Stretch zaj duab xisfeem ntau yog cov khoom tiv thaiv thiab tuaj yeem muab kev tiv thaiv nto rau cov khoom. Cov khoom tsim yog lub teeb heev, tiv thaiv cov tsos ntawm plua plav, roj, thiab noo noo, tsis muaj dej, thiab tiv thaiv tub sab. Stretch ntim tiv thaiv zaj duab xis tuaj yeem hloov kho tib lub sijhawm qhov nro tuaj yeem ua kom cov khoom nruj. Cov khoom muag muag, tshwj xeeb tshaj yog nyob rau hauv kev lag luam luam yeeb thiab kev lag luam textile, muaj cov nyhuv ntim tshwj xeeb. Cov nram qab no stretch film manufacturers yuav qhia rau koj mus yuav high-zoo stretch film. Cov txheej txheem yog dab tsi?
Ua ntej, saib cov pob tshab thiab ntsuas lub zog tensile.
Ua ntej los ntawm qhov ntev ntawm cov zaj duab xis stretch raws cov kev taw qhia ntawm lub kua muag, thiab tom qab ntawd los ntawm kab rov tav kev taw qhia ntawm lub kua muag, lub stretch ntawm stretch zaj duab xis nrog zoo tensile lub zog ntawm nws cov kev cuam tshuam muaj zog. Zoo-zoo stretch zaj duab xis stretch yuav ncav cuag 100% -300%. Cov txheej txheem cam khwb cia tau tsim los ntawm ib txheej mus rau ob-txheej thiab peb-txheej, thiab tam sim no txoj kev cam khwb cia yog siv los tsim LLDPE stretch zaj duab xis. Qhov no yog vim cam khwb cia cov kab ntau lawm muaj qhov zoo ntawm cov tuab tuab, pob tshab, thiab lwm yam, uas tuaj yeem siv rau cov kev xav tau ntawm tus nqi siab ntawm pre-stretching. Vim tias ib txheej txheej casting tsis tuaj yeem ua tau ntawm ib sab ntawm cov nplaum, cov chaw thov raug txwv. Ib leeg- thiab ob txheej cam khwb cia hauv kev xaiv cov ntaub ntawv tsis yog dav li peb-txheej cam khwb cia, thiab cov qauv kev txaus siab kuj siab, yog li peb txheej co-extruded qauv tseem zoo tagnrho. High-zoo stretch zaj duab xis yuav tsum muaj siab transparency, siab longitudinal elongation, ib tug siab yield point, siab transverse tear zog, thiab zoo puncture.
Qhov thib ob, ntsuas qhov tuab, saib seb cov yeeb yaj kiab puas muaj cov khoom me me, thiab ntsuas lub zog tensile.
Crystal point yog ib qho teeb meem zoo ntawm cov khoom siv stretch film; saib seb puas muaj cov khoom nyob rau saum npoo ntawm cov zaj duab xis stretch. Crystal point yog cov khoom siv zaj duab xis ncab ntawm cov pits me me, tseem hu ua qhov kaj; nws yog tsuas yog nyob rau hauv peb-txheej stretch zaj duab xis khoom siv ntau. Qhov laj thawj tseem ceeb yog vim kev siv silica gel synthesis; silica gel muaj kev txav mus los; Yog hais tias qhov saum npoo ntawm cov khoom siv stretch zaj duab xis ntsib qee qhov me me ntawm extrusion, nws yuav tsim ib qho chaw siv lead ua kom tsis txhob siv lead ua taw tes ntawm txoj kev, uas yog, los tiv thaiv qhov chaw ntawm cov zaj duab xis stretch.
Stretch zaj duab xis ntim ua rau cov khoom ntim kom muaj lub siab tsis sib xws, zam kev tsis sib xws uas ua rau cov khoom puas tsuaj, uas yog ib txoj kev ntim khoom (bundling, wrapping, taping, etc. ntim tsis tau). qhwv stretch zaj duab xis tus cwj pwm thiab retraction, compact, taag daim kab xev yuav khoom raws li ib tug unit, tag nrho dispersion yog me me, txawm nyob rau hauv unfavorable ib puag ncig cov khoom tsis muaj ib tug loosening thiab sib cais, tsis muaj ntse npoo thiab nplaum kom tsis txhob raug mob.
Tsis tas li ntawd, muaj cam khwb cia stretch zaj duab xis thiab tshuab stretch film.
Cast stretch film
Cam khwb cia stretch zaj duab xis ua los ntawm ib tug nruam manufacturing txheej txheem stands rau nws zoo heev clarity thiab du zoo nkauj. Cam khwb cia zaj duab xis yog notable rau nws nyob ntsiag to unwind thiab zoo heev tsim kua muag tiv thaiv uas tswj zoo heev load stability. Nws yog qhov zoo tagnrho rau cov ntawv thov uas xav tau kom meej meej thiab ua tau zoo ib yam thaum tseem tshuav nqi-zoo thiab ntau yam, ua rau nws yog qhov kev xaiv nrov thoob plaws hauv kev lag luam.
tshuab ncab zaj duab xis
Nyob rau hauv sib piv, tshuab stretch zaj duab xis undergoes ib tug siv zog-intensive txheej txheem uas extrusion thiab txias thiab muaj ntau dua puncture kuj thiab lub zog dua cam khwb cia zaj duab xis. Lub robustness ntawm cua tshuab ua rau nws zoo tagnrho rau hnyav los yog irregularly zoo li loads uas yuav tsum tau txhim khu durability thiab tsim kua muag kuj, ua rau nws yog qhov zoo tshaj plaws xaiv rau nyuaj ntim scenarios.
XH Championyog tus kws tshaj lij stretch zaj duab xis chaw tsim tshuaj paus thiab kev daws teeb meem; daws peb cov neeg siv khoom ntim cov teeb meem yog peb lub hom phiaj tseem ceeb.Tiv tauj pebtam sim no los customize koj ntim zaj duab xis.
