Akuwona wonke amaphakethe epulasitiki angahambisani nemvelo
Igama elithi "ipulasitiki" lisahlambalaza namuhla njengoba igama elithi "iphepha" lalinjalo eminyakeni engu-10 edlule, kusho umongameli weProAmpac. Ipulasitiki nayo isendleleni eya ekuvikelweni kwemvelo, ngokusho kokukhiqizwa kwezinto ezingavuthiwe, khona-ke ukuvikelwa kwemvelo kwamapulasitiki kungahlukaniswaamapulasitiki agaywe kabusha, amapulasitiki angaboli, amapulasitiki adliwayo.
- Amapulasitiki agaywe kabushaibhekisela ezintweni zokusetshenziswa zepulasitiki ezitholwe futhi ngemva kokucutshungulwa kwemfucuza yepulasitiki ngokulungiswa, ukuncibilika kwembudumbudu, ukuguqulwa nezinye izindlela ezibonakalayo noma zamakhemikhali, okuwukusetshenziswa kabusha kwamapulasitiki.
- Amapulasitiki angawohlokaamapulasitiki awonakaliswa kalula endaweni yemvelo ngokwengeza inani elithile lezithasiselo (isb. isitashi, isitashi esishintshiwe noma enye i-cellulose, ama-photosenitisers, ama-biodegraders, njll.) ohlelweni lokukhiqiza, ngokuzinza okunciphile.
- Amapulasitiki adliwayo, uhlobo lokupakisha okudliwayo, okungukuthi, ukupakisha okungadliwa, ngokuvamile akhiwa isitashi, amaprotheni, i-polysaccharide, amafutha, nezinto eziyinhlanganisela.
Ingabe ukupakishwa kwamaphepha kuhambisana nemvelo?
Ukushintsha izikhwama zepulasitiki ngezikhwama zephepha kungasho ukwanda kokugawulwa kwamahlathi, okuyoba ngokuyisisekelo ukubuyela ezindleleni zakudala zokugawulwa kwamahlathi ngokweqile. Ngaphezu kokugawulwa kwezihlahla, ukungcoliswa kwamaphepha nakho kulula ukunganakwa, eqinisweni, ukungcoliswa kwephepha kungase kube kukhulu kunokwakhiwa kwepulasitiki.
Ngokwemibiko yabezindaba, ukwenza iphepha kuhlukaniswe ngezinyathelo ezimbili: ukudonsa kanye nokwenza iphepha, futhi ukungcola kuvela ikakhulukazi enqubweni yokudonsa. Njengamanje, izigayo eziningi zephepha zisebenzisa indlela ye-alkaline yokudonsa, futhi ngethani ngalinye le-pulp elikhiqizwayo, cishe amathani ayisikhombisa amanzi amnyama azokhishwa, okungcolisa amanzi kakhulu.
Ukuvikelwa kwemvelo okukhulu kakhulu ukunciphisa ukusetshenziswa noma ukusetshenziswa kabusha
Ukukhiqizwa nokusetshenziswa okulahlwayo kuyinkinga enkulu yokungcola, ukwenqaba "okulahlwayo", ukusetshenziswa kabusha kuyahambisana nemvelo. Kuyacaca ukuthi sonke kumele sithathe izinyathelo zokunciphisa umthelela wethu emvelweni. Nciphisa, sebenzisa kabusha futhi uphinde usebenzise izindlela ezinhle zokusiza ukuvikela indawo ezungezile namuhla. Imboni yezimonyo nayo iqhubekela phambili ekufakweni okusimeme okunciphisa, ukuphinda kusetshenziswe futhi kusetshenziswe kabusha.
