Mzere wotsukira ndi kuphwanya mabotolo a PET ndi zida zonse zomwe zimakonza mabotolo a PET (monga mabotolo amadzi amchere, mabotolo a zakumwa, ndi zina zotero) kudzera mu kusanja, kuchotsa zilembo, kuphwanya, kutsuka, kuchotsa madzi, kuumitsa, ndi kusanja njira zopangira ma PET flakes oyera. Ndi mzere waukulu wopanga mapulasitiki a PET.
Ntchito Zazikulu ndi Mphamvu
• Ntchito Zazikulu: Zimapanga ma PET flakes oyera kwambiri, omwe angagwiritsidwe ntchito popanga ulusi wa mankhwala, zinthu zopakira, mapepala, ndi zina zotero. Mizere yopangira chakudya ingagwiritsidwe ntchito pobwezeretsanso kuchokera m'botolo kupita m'botolo (imafuna ziphaso za FDA ndi zina).
• Kuchuluka Kofanana: 500–6000 kg/h, kosinthika malinga ndi zofunikira, koyenera mafakitale ang'onoang'ono mpaka akuluakulu obwezeretsanso.
Kuyenda kwa Njira Yapakati (Magawo Ofunika)
1. Kutsegula ndi Kusanja Zinthu: Kutsegula zinthu, kuchotsa zinthu zodetsedwa ndi manja/makina (chitsulo, miyala, mabotolo osakhala a PET, ndi zina zotero) kuti zinthu zopangira zikhale zoyera.
2. Kuchotsa Zizindikiro: Makina ochotsera zizindikiro amalekanitsa botolo la PET ndi zilembo za PP/PE; zizindikirozo zitha kubwezeretsedwanso.
3. Kuphwanya: Chophwanya chimadula mabotolo a PET kukhala zidutswa za 10–20 mm, ndi chophimba chowongolera kukula kwake.
4. Kutsuka ndi Kusanja: Kutsuka kozizira kumalekanitsa zipewa/malembo a mabotolo; kutsuka kothina kumachotsa mafuta/zomatira; kutsuka kotentha (70–80℃, ndi yankho la alkaline) kumayeretsa ndikuchotsa madontho olimba; kutsuka kumathetsa ndikuchotsa zotsalira; kutsuka kwa magawo ambiri kumaonetsetsa kuti zinthu zili bwino.
5. Kuchotsa madzi ndi Kuumitsa: Kuchotsa madzi pogwiritsa ntchito centrifugal + kuumitsa mpweya wotentha kumachepetsa chinyezi cha flakes kufika pa ≤0.5%, zomwe zimakwaniritsa zofunikira zokonzekera pambuyo pake.
6. Kusanja ndi Kupaka Zidutswa: Kusanja mitundu/kusanja mitundu kumachotsa zidutswa zosinthika mtundu, PVC, ndi zina zotero, ndipo pamapeto pake zidutswazo zimapakidwa ndikusungidwa.
• Ntchito: Malo obwezeretsanso zinthu za PET, malo opangira ulusi wa mankhwala, malo opangira zinthu zopakira, makampani obwezeretsanso zinthu; ma flakes angagwiritsidwe ntchito popanga ulusi wa nsalu, ma phukusi a chakudya (chakudya chamtundu wanji), mapulasitiki aukadaulo, ndi zina zotero.
Zoganizira Zosankha
• Kufananiza Mphamvu: Sankhani zofunikira za zida malinga ndi zomwe zikuyembekezeredwa kuti mupewe kutaya mphamvu kapena kusakwanira mphamvu.
• Mtundu wa Zinthu Zomalizidwa: Mtundu wa chakudya umafuna njira ndi zipangizo zokonzedwa bwino; mtundu wamba wa mafakitale ukhoza kukhala ndi mawonekedwe osavuta.
• Mlingo Wodzipangira Wokha: Sankhani mzere wodzipangira wokha kapena wodzipangira wokha kutengera ndalama zogwirira ntchito ndi luso loyang'anira. • Kugwiritsa Ntchito Mphamvu ndi Kuteteza Chilengedwe: Ikani patsogolo zida zomwe zimagwiritsa ntchito mphamvu zochepa komanso zomwe zingagwiritsidwenso ntchito madzi/kutentha kuti muchepetse ndalama zogwirira ntchito komanso kuwononga chilengedwe.
