Firimu rakatambanudzwa rinowanzo shandiswa kune multilayer polyethylene elastic mafirimu, ayo anogadzirwa kushandisa firimu extrusion tekinoroji inonzi "CAST".Iyo firimu inoreva kuti chidimbu chakatetepa chezvishandiso izvi chine kunyatsoenderana uye kuchinjika kwepamusoro.
Firimu reStretch ifirimu rinotambanuka kwazvo repurasitiki rakagadzirwa nepolyethylene (PE) yakavakirwa zvinhu uye rinoshandiswa zvakanyanya kuputira pallet kuchengetedza kurodha kuitira kubata zvakanaka kwekufambisa uye kuchengetedza.
Linear yakaderera-density polyethylene (LLDPE) ndiyo yekutanga zvinhu kupa firimu kutambanudza.Mafirimu edu ane mhando yemhando yepamusoro nekuda kwemitsara yekugadzira yechizvino-zvino uye tekinoroji yepamusoro, pamwe nekushandisa zvigadzirwa zvinopihwa nevagadziri vanozivikanwa.Mafirimu e-polyethylene akarebeswa akagadzirwa kubva kune yakaderera density Polyethylene metallocene resins) m- LLDPE), Linear low-density polyethylene (LLDPE) uye yekupedzisira-yakaderera-density polyethylene (ULDPE) ine 0 uye 8% polyisobutylene (PIB).
Application
Stretch wrap/ firimu rinoshandiswa kwekutanga kuputira nekudzivirira mitoro yakarongedzwa pamapallet kune zvinhu zvega zvine hukuru hwakakura, kushandisa iyo yakatambanuka firimu ndiyo nzira inoshanda kwazvo yekurongedza nekuputira zvigadzirwa nekuda kwekudzikira kwayo uye kusimba kwepamusoro kunovimbisa kugadzikana kwemutoro. .
Tambanudza firimu / kuputira Super Power uye Simba
Ukobvu hwefirimu hwakagadzirwa hwakagadzirwa kubva pagumi kusvika pamakumi matatu neshanu micrometer yekuputira nekudzivirira zvigadzirwa uchishandisa machira ekurongedza.Yakajairwa firimu hupamhi: 500 mm, zvinogoneka kugadzira imwe hupamhi firimu mukuwanza kwe250 mm.
Chii chinonzi stretch film?
Stretch film ifirimu repurasitiki rakatetepa, rinowedzera (kazhinji rinogadzirwa nepolyethylene) rinoshandiswa kukiya nekusunga zvinhu zvinodzivirira pamapallet.Sezvo firimu rakatambanudzwa rakaputirwa pamubhedha, kukakavara kunogadzirwa uye kunoita kuti firimu riwedzere kureba kusvika ku300 times.Kukakavadzana uku kunobva kwagadzira simba rechibvumirano rakatenderedza mutoro uye rinoita kuti rirambe riri panzvimbo yawo.
Mhando dzemafirimu ekutambanudza
Kune marudzi maviri makuru eakatambanudzwa firimu: bhuku remanyorero firimu uye muchina wakatambanudza firimu.
1. Manual kutambanudza firimu
Iyo firimu yakatambanudzwa yemanyorero yakanyatsogadzirirwa kushandiswa kwemaoko uye saka inowanzo shandiswa mune yakaderera vhoriyamu mukurongedza uye kuputira mashandiro.Yakave yakatariswa kune manual packaging.Ukobvu hwefirimu rakagadzirwa hunobva pagumi kusvika ku40 micrometer uye hupamhi huri 450 mm kana 500 mm, tensile 100% yakavimbiswa.Firimu iri rakagadzirwa pamichina otomatiki ine zvivakwa zvinodzora kureba uye huremu hwefirimu riri pamupumburu.
2. Machine kutambanudza firimu
Muchina wakatambanudza firimu ifirimu rakanyatsogadzirirwa kushandiswa mumashini ekuputira uye rinowanzo shandiswa muhombe vhoriyamu kurongedza uye kuputira mashandiro.Mamwe marudzi akajairika emashini ekutambanudza mafirimu anosanganisira:
-Blown Stretch Firimu- Inogadzirwa uchishandisa yakafuridzwa extrusion maitiro.Iyi nzira inosanganisira kuvhuvhuta inopisa resin mububble.Bubble rinobva rashanduka kuita mapepa anokungurutswa oiswa kune core chubhu.
Cast Stretch Firimu- Inoitwa uchishandisa extrusion maitiro.Iyi nzira inosanganisira kudyisa mashizha anopisa kuburikidza nemutsara wemvura yakanyoroveswa, iyo inobva yasimbisa firimu.
Pre-Stretched film- Ifirimu rakatowedzerwa mumatanho ekugadzira.
