Akuzona zonke izinto zokupakisha zepulasitiki ezingakhiqizi imvelo
Igama elithi "ipulasitiki" liyisihlamba namuhla njengoba igama elithi "iphepha" lalinjalo eminyakeni eyi-10 eyedlule, kusho umongameli we-ProAmpac. Ipulasitiki nayo isendleleni eya ekuvikelweni kwemvelo, ngokusho kokukhiqizwa kwezinto zokusetshenziswa, khona-ke ukuvikelwa kwemvelo kwepulasitiki kungahlukaniswa kubeamapulasitiki asetshenziswe kabusha, amapulasitiki abolayo, amapulasitiki adliwayo.
- Amapulasitiki asetshenziswe kabushaibhekisela ezintweni zokusetshenziswa zepulasitiki ezitholwe futhi ngemva kokucutshungulwa kwepulasitiki elahliwe ngokusebenzisa ukwelashwa kwangaphambili, ukuncibilikisa i-granulation, ukuguqulwa kanye nezinye izindlela zomzimba noma zamakhemikhali, okuwukusetshenziswa kabusha kwepulasitiki.
- Amapulasitiki abolakalayoyipulasitiki ebola kalula endaweni yemvelo ngokufaka inani elithile lezithasiselo (isb. isitashi, isitashi esiguquliwe noma enye i-cellulose, ama-photosensitizer, ama-biodegraders, njll.) enkambisweni yokukhiqiza, ngokuqina okunciphile.
- Amapulasitiki adliwayo, uhlobo lokupakisha okudliwayo, okungukuthi, ukupakisha okungadliwa, ngokuvamile kwakhiwe isitashi, amaprotheni, ama-polysaccharide, amafutha, kanye nezinto ezihlanganisiwe.
Ingabe ukupakisha amaphepha kunobungani nemvelo?
Ukufaka izikhwama zepulasitiki esikhundleni sezikhwama zephepha kungasho ukwanda kokugawulwa kwamahlathi, okuyoba ukubuyela ezindleleni zakudala zokugawulwa kwamahlathi ngokweqile. Ngaphezu kokugawulwa kwamahlathi, ukungcoliswa kwamaphepha kulula futhi ukunganakwa, empeleni, ukungcoliswa kwamaphepha kungaba kukhulu kunokwenziwa kwepulasitiki.
Ngokusho kwemibiko yabezindaba, ukwenza iphepha kuhlukaniswe ngezinyathelo ezimbili: ukugaya kanye nokwenza iphepha, kanti ukungcola kuvela kakhulu enkambisweni yokugaya. Njengamanje, iningi lezindawo zokugaya iphepha zisebenzisa indlela ye-alkaline yokugaya, futhi ngethani ngalinye le-pulp elikhiqizwayo, kuzokhishwa cishe amathani ayisikhombisa amanzi amnyama, okungcolisa kakhulu ukutholakala kwamanzi.
Ukuvikelwa kwemvelo okukhulu kakhulu ukunciphisa ukusetshenziswa noma ukusetshenziswa kabusha
Ukukhiqizwa nokusetshenziswa kwezinto ezilahlwayo kuyinkinga enkulu yokungcola, ukwenqaba "okulahlwayo", ukusetshenziswa kabusha kuyavikela imvelo. Kusobala ukuthi sonke sidinga ukuthatha isinyathelo sokunciphisa umthelela wethu emvelweni. Ukunciphisa, ukusebenzisa kabusha kanye nokuvuselela kabusha kuyizindlela ezinhle zokusiza ukuvikela imvelo namuhla. Imboni yezimonyo nayo iqhubekela phambili ekupakisheni okusimeme okunciphisa, okusebenzisa kabusha kanye nokuvuselela kabusha.
