Kutheni kufuneka kuphuhliswe imathiriyeli yokupakisha enokuphinda isetyenziswe?
Kuphononongo olupapashwe kwijenali yezemfundo yaseU.S. ebizwa 《SAYENSI》, abaphandi baseUnited States naseOstreliya babonisa ukuba “malunga nezigidi ezisi-8 zeetoni zenkunkuma yeplastiki ingena elwandle minyaka le.”
Ngokutsho kwenye ingxelo, uphando lukaLaurence Morris, isifundiswa seFrench Academy of Development uphando lubonisa ukuba “nyaka ngamnye izinto eziphilayo zaselwandle ezizizigidi ezili-15 zibulawa yiplastiki.”
Ithini isikhokelo sophuhliso lwezinto zokupakisha kwixesha elizayo?
A. Nciphisa ukusetyenziswa.
a. Ngokusebenzisa ifomyula, qinisekisa ukuba ukusebenza kuhlala kungatshintshwangaemva kokunciphisa ubunzima.
Umzekelo:
1. PET12um ukuya PET7um
2. BOPA15um ukuba BOPA10um
3. I-Alox PET12 ukuya kwi-Alox PET 10um, njl.
b. Nciphisa ukusetyenziswa kweepakethe zeplastiki ezilahlwayo
c. Phucula izinga lokuphinda lisetyenziswe kwizinto zokupakisha
B. Ukukhawulezisa ukwandiswa kwemigca yokuvelisa izinto ezonakeleyo
Ukufika komyalelo wothintelo lweplastiki kwenze ukuba izinto ezingonakaliswayo zebhayoloji ezinokuthi zigalelwe umhlaba kwaye zithotywe ngokwenziwa komgquba owenziwe nge-aerobic phantsi kweemeko zokufuma nobushushu obunxulumeneyo zifumana amathuba azo okuphuhlisa .
C. Ukusetyenziswa kwakhona kwezinto ezinokuphinda zisetyenziswe kunye ne-mono
Ukusuka kwiintlobo ngeentlobo zemathiriyeli ezinendibaniselwano yokusebenza eyahlukileyo ukuya kwisixhobo se-mono esineempawu ezininzi, ezilungele ukurisayikilishwa, ukusetyenziswa kwakhona kobutyebi. Olu lukhokelo oluphuhlayo lokupakishwa kwixesha elizayo.
Umzekelo:
1. PE/PE
2. Multi-layer co-extrusion PE
3. BOPP/CPP
4.Iingxowa zePhepha (Ziyakwazi ukurisayikilisha, zinokonakala)
5. Izinto zeMono
I-PE / PE-Ingasetyenziselwa ukuvelisa isikhwama sokuma kunye ne-zipper, ibhegi etywiniweyo yamacala amathathu
I-PP/PP-Ingasetyenziselwa ukuvelisa isitokhwe sokupakisha esizihambelayo, Ingxowa emithathu etywiniweyo esecaleni kunye nengxowa yokuma eneziphu
I-PETG, PP-Izinto ezinjalo ze-mono zingasetyenziselwa ukuvelisa ileyibhile yebhotile
Iphepha / Iphepha- Esi sakhiwo sinokusetyenziswa njengengxowa yangaphakathi nangaphandle yokupakisha ukukhanya okunje ngeelekese, ithoyi, njl.
------------------------------------Ukwabelana ngamatyala---------------- -------------------
| Isakhiwo seClassic | Ulwakhiwo olunokurisayiklishwa | Ukugcinwa kweendleko | Phawula |
| NY15/PE135 | PE75/PE75 | 10%-20% | Ingxowa yerayisi / ibhegi yomgubo (Ngaphandle komqheba weplastiki) |
| PET12/NY15/PE130 | PE50/PE110 | 15%-25% | Liquid stand up pouch |
| PET12/PE95 | PE50/PE50 | 15%-25% | Ibhegi engumkhenkce, ingxowa yokupakisha yomkhenkce |
Ukuba unayo nayiphi na imibuzo, nceda uzive ukhululekile ukuqhagamshelana nathi. I-Baojiali iya kuhlala ikubonelela ngesisombululo sokupakisha esikulungeleyo.
