Mabhegi epurasitiki anoongororwa sei? Chii zvachokuongorora mitemoemabhegi epurasitiki anoshandiswa mukurongedza chikafu?
Kutora zviyero uye zvikamu
1. Mumba chiyero chekuongorora bhegi repurasitiki: GB/T 41168-2021 Purasitiki nealuminium foil inoumba firimu nebhegi rekurongedza chikafu.
2. Kuronga
-Maererano nechimiro: Mabhegi epurasitiki echikafu akakamurwa kuita Kirasi A uye Kirasi B zvinoenderana nechimiro
-Yakakamurwa netembiricha yekushandiswa: Mabhegi epurasitiki echikafu akaiswa mugiredhi rekubikira, semi yakakwira tembiricha yekupisa giredhi, uye tembiricha yekupisa giredhi zvinoenderana nekupisa kwekushandisa.
Chitarisiko uye hunyanzvi
-Ona tarisa pasi pechiedza chechisikigo uye kuyera nechiyereso chishandiso chine chokwadi chisingasviki 0.5mm:
-Wrinkles: Makwinya mashoma anopindirana anobvumidzwa, asi asingapfuure 5% yenzvimbo yechigadzirwa;
-Kukwenya, kupisa, punctures, adhesion, zvinhu zvekunze, delamination, uye tsvina hazvibvumidzwe;
-Elasticity yefirimu roll: hapana kutsvedza pakati pemafirimu rolls kana ichifamba;
-Film roll yakazaruka kusimbisa: Kusimbisa kudiki kwakafumurwa kusingakanganisi kushandiswa kunobvumirwa;
-Kusaenzana kwefirimu roll kupera chiso: kwete kupfuura 2mm;
-Iyo inopisa yekuisa chisimbiso chikamu chebhegi chakanyatso sandara, pasina chero yakasununguka chisimbiso, uye inobvumira mabhubhu asingakanganisi kushandiswa kwayo.
Packaging/Identification/Labeling
Imwe neimwe pasuru yechigadzirwa inofanirwa kuperekedzwa nechitupa chekuenderana uye inoratidza zita rechigadzirwa, chikamu, zvakatemwa, mamiriro ekushandisa (tembiricha, nguva), huwandu, mhando, batch nhamba, zuva rekugadzira, inspector kodhi, yekugadzira unit, yekugadzira unit kero. , kuuraya chiyero nhamba, nezvimwe.
Zvenyama uye zvemuchina kuita zvinodiwa
1. Kunhuwa kusingaite
Kana chinhambwe kubva kumuenzaniso webvunzo chiri pasi pe100mm, ita bvunzo yekunhuhwirira uye pasina kunhuhwirira kwakashata.
2.Connector
3.Plastic bhegi yekuongorora - saizi kutsauka:
3.1 Kutsauka kwesaizi yefirimu
3.2 Saizi yekutsauka kwemabhegi
Kutsauka kwehukuru hwebhegi kunofanirwa kuenderana nezvinodiwa mutafura iri pazasi. Kupisa kwekuvhara kwehupamhi hwebhegi kuchayerwa nemudziyo wekuyeresa nekururama kusingasviki 0.5mm.
4 Plastic Bag Inspection - Yemuviri uye Mechanical Properties
4.1 Peel simba rebhegi
4.2 Kupisa kwekuvhara simba kwebhegi
4.3 Kusimba kwesimba, kushushikana kwezita panguva yekuzorora, kona yekurudyi kubvarura simba, uye kuramba pendulum simba rekuita.
Chimiro chinotora chimiro chetambo refu, nehurefu hwe150mm uye hupamhi hwe15mm ± 0.3mm. Kupatsanurwa pakati pezvigadziriso zvematayera i100mm ± 1mm, uye kutatamuka kwechimiro i200mm/min ± 20mm/min.
4.4 Plastic bhegi mvura mhute permeability uye oxygen permeability
Panguva yekuedza, nzvimbo yekusangana yezviri mukati inofanira kutarisana nedivi rekumanikidzwa kwepasi kana kuti yakaderera yehutsi hwemvura, ine tembiricha yekuyera ye38 ° ± 0.6 ° uye hunyoro hwe90% ± 2%.
4.5 Kudzvinyirirwa kupikisa kwemabhegi epurasitiki
4.6 Kudonha kuita kwemabhegi epurasitiki
4.7 Kupisa kupisa kwemabhegi epurasitiki
Mushure meyedzo yekupisa kupisa, hapafanirwe kuve nekubuda kwemavara, deformation, interlayer peeling, kana kupisa kuvharira kupeuka uye zvimwe zvisingaite. Kana iyo sampuli chisimbiso chaputswa, zvinodikanwa kutora sampuli uye kuitazve.
Kubva pakudya kutsva kusvika pakugadzirira kudya chikafu, kubva pazviyo kusvika kunyama, kubva kune imwe neimwe kurongedza kuenda kukutakura kwekutakura, kubva kune yakasimba chikafu kusvika kune yemvura chikafu, mabhegi epurasitiki ave chikamu cheindasitiri yezvekudya. Izvo zviri pamusoro ndiwo zviyero uye nzira dzekuongorora mabhegi epurasitiki anoshandiswa mukurongedza chikafu kuti ave nechokwadi chekuchengetedza chikafu.
