Ngophuhliso olukhawulezayo lweshishini lokupakisha, ukusungulwa kwetekhnoloji yesicelo semathiriyeli kunye nokunyuswa kwengqwalasela yabantu yokukhuselwa kwendalo, ukupakishwa ngakumbi kweplastiki kwenziwa ngezinto ezinobungane bokusingqongileyo.Ukuba ngokwemveliso yezinto eziluhlaza, ke ezona ndidi zintathu ziphambili. yeengxowa zeplastiki zokusingqongileyo: iplastiki esetyenzisiweyo, iplastiki eyonakalayo kunye neplastiki etyiwayo.
Iplastiki eRecycled
Iplastiki esetyenzisiweyo kukusetyenziswa kwakhona kweplastiki, ngomatshini wokusila ngencakuba, ukuze kugqitywe ukusetyenziswa kwakhona kweplastiki.
Iplastiki esetyenzisiweyo ibhekiselele kwizixhobo zeplastiki ekrwada ezifunyenwe kwakhona emva kokulungiswa kwenkunkuma yeplastiki ngeendlela zomzimba okanye zekhemikhali ezinje ngonyango lwangaphambili, ukunyibilika kwegranulation kunye nokuguqulwa, okukuphinda kusetyenziswe iplastiki.
Iinzuzo ezinkulu zeplastiki esetyenzisiweyo ngokuqinisekileyo zinexabiso eliphantsi kunexabiso elitsha lezinto eziphathekayo, nangona ikwintsebenzo iyonke kwaye iipropati azilunganga njengoko izinto ezintsha zomelele, kodwa akufuneki sisebenzise kwiimveliso ezininzi ezenziwe iipropathi kunye. ukusebenza kwayo yonke imathiriyeli elungileyo ukuyenza, ukuze uchithe uninzi lweempawu ezingeyomfuneko, kunye nezinto ezihlaziyiweyo zahlukile, ngokweemfuno ezahlukeneyo, Kufuneka kuphela ukujongana nomba othile wophawu, unokwenza imveliso ehambelanayo. , ukuze kungabikho ukulahlekelwa kwezibonelelo.
IPlastiki eyonakaliswayo
Iiplastiki ezichithwayo zibhekisela kwiiplastiki ezichithwa ngokulula kwindawo yendalo ngenxa yokongezwa kwezongezo ezithile (ezifana nesitashi, isitashi esilungisiweyo okanye enye i-cellulose, i-photosensitizer, i-agent ye-biodegradation, njl.) kwinkqubo yokuvelisa.Iiplastiki ezinokonakala ziwela kwiindidi ezine eziphambili:
1.IPlastiki enokunyanyiswa yizinto eziphilayo
Yomile, akufuneki ukuba uphephe ukukhanya, uluhlu olubanzi lwezicelo, hayi kuphela zingasetyenziselwa ifilimu yeplastiki yezolimo, iingxowa zokupakisha, kwaye zisetyenziswa ngokubanzi kwintsimi yeyeza.Ngokuphuhliswa kobugcisa bebhayoloji bale mihla, iiplastiki ezingonakaliswa ngebhayoloji ziye zanikwa ingqwalasela ethe chatha kwaye zaba yindawo entsha eshushu kuphando nakuphuhliso.
2.Plastiki eyonakaliswayo
I-photosensitizer yongezwa kwiplastiki ukuyichitha kancinci phantsi kokukhanya kwelanga.Kungokwesizukulwana sangaphambili seeplastiki ezichithwayo, kwaye ukungonakali kwayo kukuba ixesha lokuthotywa alinakwenzeka ngenxa yokukhanya kwelanga kunye nokutshintsha kwemozulu, ngoko akunakwenzeka ukulawula ixesha lokuthotywa.
3.Ukuthotywa kwamanzi kwiPlastiki
Yongeza izinto ezifunxa amanzi kwiplastiki, emva kokusetyenziswa, ukulahla emanzini kunganyibilika, ikakhulu kusetyenziswe kumayeza kunye nezixhobo zempilo (ezifana neeglavu zonyango), kulula ukutshabalalisa kunye nonyango lwe-disinfection.
4. IPlastiki eKhanya/enokubola
Ukuthotywa kwefoto kunye nokudityaniswa kwe-microbial yeklasi yeplastiki, inokuthotywa kokukhanya kunye ne-microbial yeempawu zeplastiki.
IiPlastiki ezityiwayo
Iplastiki etyiwayo luhlobo lwepakethe etyiwayo, oko kukuthi, ukupakishwa okutyiwayo, okubandakanya isitashi, iprotein, i-polysaccharide, amanqatha, izinto ezixubeneyo, ezisetyenziswa ngokubanzi njengokusonga iplastiki, ifilimu yokupakisha, ukupakishwa okuphezulu, ukupakishwa kokutya, ukupakishwa kwepastry, ukupakishwa kwesinongo, njl.
Ngophuhliso lweshishini lokutya lanamhlanje, ukupakishwa kokutya kuhlaziywa rhoqo.Uhlobo olutsha lwezinto zobuchwepheshe bokupakisha ukutya, ukupakishwa okudliwayo, okunokuphucula ukuchasana phakathi kwezinto zokupakisha kunye nokukhuselwa kwendalo, kuvelele.Izinto zokupakisha ezidliwayo zibhekisela kwizinto ezikhethekileyo zokupakisha ezinokuguqulwa zibe yinto edliwayo ekrwada yezilwanyana okanye abantu emva kokuba umsebenzi wokupakisha uphunyeziwe.Izinto zokupakisha ezidliwayo luhlobo lokupakisha ngaphandle kwenkunkuma, luhlobo lwezixhobo ezisekelwe kwimithombo yokupakisha izinto zokupakisha.
