Cov kab ntau lawm ntxuav thiab zom cov raj mis yas yog siv rau kev rov ua dua tshiab thiab rov siv dua

Cov kab ntau lawm ntxuav thiab zom cov fwj PET yog cov khoom siv ua tiav uas ua cov fwj PET pov tseg (xws li cov fwj dej ntxhia, cov fwj dej haus, thiab lwm yam) los ntawm kev cais, tshem daim ntawv lo, zom, ntxuav, tshem dej, ziab, thiab cais cov txheej txheem kom tsim cov PET flakes huv. Nws yog cov kab ntau lawm tseem ceeb rau kev rov ua dua yas PET.

Cov Kev Siv Tseem Ceeb thiab Peev Xwm
• Siv Tseem Ceeb: Tsim cov PET flakes uas muaj cov khoom huv siab, uas siv tau rau cov tshuaj fiber filaments, cov ntaub ntawv ntim khoom, cov ntawv, thiab lwm yam. Cov kab noj khoom haus siv tau rau kev rov ua dua tshiab los ntawm lub raj mis mus rau lub raj mis (yuav tsum muaj FDA thiab lwm daim ntawv pov thawj).
• Muaj Peev Xwm Siv Tau: 500–6000 kg/h, kho tau raws li qhov yuav tsum tau ua, tsim nyog rau cov chaw tsim khoom siv dua tshiab me mus rau loj.
Cov Txheej Txheem Tseem Ceeb (Cov Theem Tseem Ceeb)
1. Qhib thiab xaiv ua ntej: Qhib, tshem tawm cov khoom tsis huv (hlau, pob zeb, lub raj mis uas tsis yog PET, thiab lwm yam) los ntawm tes/tshuab kom cov khoom siv raw huv dua.
2. Kev Tshem Tawm Daim Ntawv: Lub tshuab tshem daim ntawv cais lub cev fwj PET ntawm cov ntawv PP/PE; cov ntawv tuaj yeem rov ua dua tshiab.
3. Kev tsoo: Lub tshuab tsoo txiav cov fwj PET ua cov nplais 10–20 hli, nrog rau lub vijtsam tswj qhov loj.
4. Ntxuav thiab cais: Ntxuav txias cais cov hau fwj/daim ntawv lo; ntxuav sib txhuam tshem tawm cov roj/cov nplaum; ntxuav kub (70–80 ℃, nrog cov kua alkaline) tua kab mob thiab tshem tawm cov xim tawv ncauj; yaug kom tsis muaj zog thiab tshem tawm cov seem; ntxuav ntau theem kom huv si.
5. Kev Tshem Dej thiab Kev Ziab: Kev tshem dej centrifugal + cua kub kom qhuav txo cov dej noo ntawm cov flakes rau ≤0.5%, ua tau raws li cov kev cai ua tom qab.
6. Kev Cais thiab Ntim Khoom Zoo: Kev Cais Xim/Kev Cais Qhov Ceev Tshem Tawm Cov Nplaum Uas Tsis Muaj Xim, PVC, thiab lwm yam, thiab thaum kawg Cov Nplaum raug Ntim thiab Khaws Cia.
• Cov Kev Siv: Cov chaw tsim khoom siv rov ua dua PET, cov chaw tsim khoom siv tshuaj fiber, cov chaw tsim khoom ntim khoom, cov chaw tsim khoom siv rov ua dua tshiab; cov flakes tuaj yeem siv rau cov fibers textile, cov khoom ntim khoom noj (qib khoom noj), cov yas engineering, thiab lwm yam.

Kev Xav Txog Kev Xaiv
• Kev Sib Piv Peev Xwm: Xaiv cov lus qhia txog cov khoom siv raws li qhov xav tau kom tsis txhob muaj peev xwm pov tseg lossis muaj peev xwm tsis txaus.
• Qib Khoom Tiav Lawm: Qib khoom noj xav tau cov txheej txheem thiab cov ntaub ntawv zoo dua; qib kev lag luam ib txwm muaj peev xwm muaj qhov kev teeb tsa yooj yim dua.
• Qib Kev Ua Haujlwm Tsis Siv Neeg: Xaiv ib txoj kab ua haujlwm ib nrab lossis ua haujlwm tsis siv neeg tag nrho raws li tus nqi ua haujlwm thiab kev tswj hwm. • Kev Siv Hluav Taws Xob thiab Kev Tiv Thaiv Ib Puag Ncig: Xaiv cov khoom siv uas siv hluav taws xob tsawg thiab muaj peev xwm rov ua dua dej/kub kom txo tau cov nqi khiav lag luam thiab kev cuam tshuam rau ib puag ncig.
