Kusiyana Pakati pa PET ndi PVC Mapepala
Mapepala a PET
Mapepala a PET ndi ma polima a thermoplastic opangidwa ndi polymerizing terephthalic acid ndi ethylene glycol. Amawonetsa kuwonekera bwino komanso gloss, mphamvu zamakina apamwamba, komanso kukana kutentha kwabwino. Mapepala a PET amakhalanso ndi kukana kwamphamvu komanso kukana kwa dzimbiri, kuwapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira mphamvu zambiri komanso kuwonekera poyikapo.
Zithunzi za PVC
Mapepala a PVC amapangidwa kuchokera ku polymerization ya vinyl kolorayidi monomers, ndi plasticizers zosiyanasiyana anawonjezera kukwaniritsa misinkhu yosiyanasiyana kusinthasintha. Mapepala a PVC ali ndi mawonekedwe otsika komanso onyezimira koma olimba kwambiri amakina komanso kukana mankhwala. Komabe, kukana kwawo kutentha kumakhala kotsika; amatha kupunduka ndi kuwola pa kutentha kwakukulu, kutulutsa zinthu zovulaza, motero zimafuna kulamulira bwino kutentha pakugwiritsa ntchito.
Kugwiritsa ntchito Mapepala a PET
a. Kupaka Chakudya: Chifukwa cha zinthu zake zopanda poizoni komanso zopanda fungo, mapepala a PET amagwiritsidwa ntchito kwambiri popaka zakudya, monga mabotolo akumwa, zotengera zakudya, ndi mathireyi.
b. Packaging Medical: Kuwonekera kwakukulu komanso zotchinga zabwino kwambiri zamapepala a PET zimawapangitsa kukhala chisankho chomwe amakonda pakuyika zachipatala, kuphatikiza zopangira mankhwala ndi zida zamankhwala.
c. Electronic Product Packaging: PET sheets 'kutchinjiriza kwakukulu kwamagetsi ndi mphamvu zamakina zimawapangitsa kuti azigwiritsidwa ntchito kwambiri pakuyika ndi kuteteza zinthu zamagetsi.
Kugwiritsa ntchito Mapepala a PVC
a. Zipangizo Zomangira: Kukana kwamankhwala ndi mawonekedwe osatsimikizira chinyezi a mapepala a PVC amawapangitsa kuti azigwiritsidwa ntchito kwambiri muzomangira, monga mapanelo a khoma, pansi, ndi zida zofolera.
b. Chizindikiro Chotsatsa: Kusavuta kukonza mapepala a PVC komanso kutsika mtengo kumawapangitsa kukhala chisankho chofala pazikwangwani zotsatsa, matabwa owonetsera, ndi zida zosindikizira.
c. Mipope ndi Mbiri: Chifukwa cha mphamvu zawo zamakina komanso kukana dzimbiri, mapepala a PVC amagwiritsidwa ntchito kwambiri m'mapaipi ndi mbiri, monga mapaipi a ngalande ndi mbiri zamawindo.
Kuchita Kwachilengedwe kwa Mapepala a PET
Mapepala a PET ali ndi ubwino wambiri pokhudzana ndi chilengedwe. Choyamba, PET zinthu ndi 100% recyclable; itha kusinthidwa kukhala zinthu zatsopano za PET, kuchepetsa zinyalala zazinthu komanso kuwononga chilengedwe. Kachiwiri, mapepala a PET samatulutsa zinthu zovulaza panthawi yopanga ndikugwiritsa ntchito, zomwe zimawononga chilengedwe komanso thanzi la anthu.
Nkhani Zachilengedwe za Mapepala a PVC
Poyerekeza ndi mapepala a PET, mapepala a PVC ali ndi zovuta zambiri zachilengedwe. Choyamba, kukonzanso zinthu za PVC ndizovuta, zokwera mtengo komanso ukadaulo wovuta. Kachiwiri, mapepala a PVC amatha kutulutsa ma chloride owopsa ndi opangira pulasitiki panthawi yopanga ndikugwiritsa ntchito, zomwe zingawononge chilengedwe komanso thanzi la anthu. Kuphatikiza apo, mapepala a PVC amawola pakatentha kwambiri, kutulutsa mpweya wapoizoni womwe umasokoneza mpweya wabwino.
Posankha pakati pa mapepala a PET ndi PVC, kuganizira mozama za zosowa zenizeni za ntchito ndi zinthu zachilengedwe ndizofunikira:
Pazinthu zoyikapo zomwe zimafuna kuwonekera kwambiri komanso mphamvu, monga chakudya ndi ma CD azachipatala, mapepala a PET amayenera kukondedwa.
Kuti agwiritsidwe ntchito m'mafakitale omanga ndi otsatsa, komwe mtengo ndi magwiridwe antchito ndizofunikira, mapepala a PVC atha kukhala oyenera.
Pankhani ya kukhazikika kwa chilengedwe, mapepala a PET ali ndi ubwino wambiri, kuwapangitsa kukhala oyenera kwambiri kwa mapulogalamu omwe ali ndi zofunikira zachilengedwe.
Mapepala a PET ndi PVC amasiyana kwambiri pakugwira ntchito, kugwiritsa ntchito, komanso kukhudzidwa kwachilengedwe. Mapepala a PET, omwe ali ndi mawonekedwe abwino kwambiri komanso momwe angagwiritsire ntchito chilengedwe, amagwiritsidwa ntchito kwambiri muzakudya, zamankhwala, ndi zopangira zamagetsi. Mosiyana ndi izi, mapepala a PVC, omwe amadziwika kuti ali ndi mphamvu zamakina abwino komanso otsika mtengo, amagwiritsidwa ntchito kwambiri pomanga ndi zikwangwani zotsatsa. Komabe, pakuwonjezeka kwachidziwitso cha chilengedwe, mapepala a PET akuyembekezeka kugwiritsa ntchito kwambiri komanso chitukuko mtsogolomu.
Makina athu a Automatic Vacuum Forming atha kugwiritsidwa ntchito ndi mapepala onse awiri
1. The makina a vacuum thermoforming ili ndi dongosolo lowongolera servo la nkhungu zam'mwamba ndi zam'munsi, komanso kudyetsa, zomwe zimapereka kukhazikika komanso kulondola panthawi yopanga.
2. Makina opangira makina opangira pulasitiki amakhala ndi mawonekedwe apamwamba okhudza mawonekedwe a makina a anthu omwe amalola ogwira ntchito kuyang'anira ndikusintha magawo onse kuti agwire bwino ntchito. Izi zimathandiziranso kuti ogwiritsa ntchito azitha kuzigwiritsa ntchito ndikuwonetsetsa kuti zinthu zikuyenda bwino.
3. Kuphatikiza pa kayendetsedwe kake kapamwamba kameneka, makina atsopano opangira vacuum alinso ndi ntchito yodziwonetsera yokha yomwe imasonyeza zenizeni zenizeni zenizeni, zomwe zimapangitsa kuti zikhale zosavuta kuzindikira ndi kuthetsa nkhani mwamsanga. Kuchita izi kumathandiza kuchepetsa nthawi yopuma ndikuwonjezera zokolola.
4. Chinthu china chofunika cha makina onse opangira vacuum ndi kuthekera kwake kusunga magawo angapo azinthu, zomwe zimalola ogwiritsa ntchito kuyesa mwachangu ndikusintha makina pazoyendetsa zosiyanasiyana. Izi zimathandizira kuti makinawo azisinthasintha komanso zimathandizira kuchepetsa nthawi yopangira zinthu, zomwe zimapangitsa opanga kuyankha mwachangu pakufunika kwa msika.
Poyerekeza ndi kusanthula kusiyana kumeneku, tingathe kumvetsa bwino ubwino ndi kuipa kwa mapepala a PET ndi PVC, zomwe zimatilola kupanga zisankho zodziwika bwino muzogwiritsira ntchito.
Katswiri wopanga makina opangira kutentha.
