Ngokuthuthuka okusheshayo kwemboni yokupakisha, ukusungulwa kobuchwepheshe bokusebenzisa izinto ezibonakalayo kanye nokunaka okwandayo komqondo wabantu wokuvikela imvelo, ukupakishwa okwengeziwe kwepulasitiki kwenziwa ngezinto ezihambisana nemvelo.Uma ngokusho kokukhiqizwa kwezinto ezingavuthiwe, khona-ke izigaba ezintathu eziyinhloko wezikhwama zepulasitiki zemvelo: ipulasitiki egaywe kabusha, ipulasitiki eyonakalayo kanye nepulasitiki edliwayo.
Ipulasitiki Esenziwe Kabusha
Ipulasitiki egaywe kabusha iwukusetshenziswa kabusha kwepulasitiki, ngokusebenzisa umshini wokugaya i-blade, ukuze kuqedelwe ukusetshenziswa kabusha kwepulasitiki.
Ipulasitiki egaywe kabusha isho izinto zokusetshenziswa zepulasitiki ezitholwe futhi ngemva kokucubungula ipulasitiki yemfucuza ngezindlela ezibonakalayo noma zamakhemikhali ezifana nokwelashwa kusengaphambili, ukuncibilika kwembudumbudu kanye nokuguqulwa, okuwukusetshenziswa kabusha kwepulasitiki.
Izinzuzo ezinkulu kakhulu zepulasitiki esenziwe kabusha nakanjani zishibhile kunentengo entsha yezinto ezibonakalayo, noma zisebenza ngokuphelele futhi izakhiwo zingezinhle njengoba izinto ezintsha ziqinile, kepha asikho isidingo sokusebenzisa emikhiqizweni eminingi eyenziwe ukusebenza kwayo yonke into enhle ukuyenza, ngakho-ke lokho kwamosha izimfanelo eziningi ezingadingekile, futhi izinto ezenziwe kabusha zihlukile, ngokuya ngezidingo ezahlukahlukene, Isidingo kuphela sokucubungula isici esithile semfanelo, singenza umkhiqizo ohambisanayo. , ukuze kungabikho ukulahlekelwa kwezinsiza.
Ipulasitiki Ewohlokayo
Amapulasitiki awonakaliswayo abhekisela kumapulasitiki awonakaliswa kalula endaweni yemvelo ngenxa yokwengezwa kwezithasiselo ezithile (njengesitashi, isitashi esishintshiwe noma enye i-cellulose, i-photosensitizer, i-agent ye-biodegradation, njll.) ohlelweni lokukhiqiza.Amapulasitiki awonakalayo awela ezigabeni ezine eziyinhloko:
1.I-Biodegradable Plastic
Dry, akudingeki ukugwema ukukhanya, anhlobonhlobo izicelo, hhayi kuphela ingasetshenziswa kwezolimo plastic ifilimu, izikhwama emaphaketheni, futhi kabanzi emkhakheni wezokwelapha.Ngokuthuthukiswa kwe-biotechnology yesimanje, amapulasitiki abolayo asenakwe kakhulu futhi abe yindawo entsha eshisayo ocwaningweni nasekuthuthukisweni.
2.Plastiki ebolekayo
I-photosensitizer yengezwa epulasitiki ukuze ihlehle kancane kancane ngaphansi kokukhanya kwelanga.Kungokwesizukulwane sangaphambili samapulasitiki awonakalayo, futhi ukonakala kwawo ukuthi isikhathi sokuwohloka asinakubikezelwa ngenxa yokukhanya kwelanga nokushintsha kwesimo sezulu, ngakho-ke akunakwenzeka ukulawula isikhathi sokuwohloka.
3.Ukucekelwa phansi kwamanzi kwePlastiki
Engeza izinto ezimunca amanzi epulasitiki, emva kokusetshenziswa, ukulahla emanzini kungancibilika, ikakhulukazi ezisetshenziswa kwezokwelapha kanye nezempilo (njengamagilavu ezokwelapha), kulula ukubhubhisa kanye nokwelashwa kwe-disinfection.
4. Ipulasitiki ekhanyayo/engaboli
I-Photodegradation kanye nenhlanganisela ye-microbial yekilasi lepulasitiki, inokuwohloka okukhanyayo nokuncane kwezimpawu zepulasitiki.
Ipulasitiki Edliwayo
Ipulasitiki edliwayo iwuhlobo lokupakisha okudliwayo, okungukuthi, okudliwayo, okuvamise ukuhlanganisa isitashi, amaprotheni, i-polysaccharide, amafutha, izinto eziyinhlanganisela, ezisetshenziswa kabanzi njengokugoqa ipulasitiki, ifilimu yokupakisha, ukupakisha amaphuzu aphezulu, ukupakisha ukudla, ukupakishwa kwekhekhe, ukupakishwa kwesinongo, njll.
Ngokuthuthuka kwemboni yesimanje yokudla, ukupakishwa kokudla kubuyekezwa njalo.Uhlobo olusha lwezinto zobuchwepheshe bokupakisha ukudla, ukupakishwa okudliwayo, okungathuthukisa ukungqubuzana phakathi kwezinto zokupakisha nokuvikelwa kwemvelo, kuyagqama.Izinto zokupakisha ezidliwayo zisho into yokupakisha ekhethekile engaguqulwa ibe impahla eluhlaza edliwayo yezilwane noma abantu ngemuva kokuba umsebenzi wokupakisha usufezekile.Izinto zokupakisha ezidliwayo ziwuhlobo lokupakisha ngaphandle kokumosha, kuwuhlobo lwempahla yokupakisha yokuvikela imvelo esekwe esisetshenziswa.
