Ayizizo zonke iipakethe zeplastiki ezingalungelelani nokusingqongileyo
Igama elithi "iplastiki" lihlazo namhlanje njengoko igama elithi "iphepha" lalinjalo kwiminyaka eli-10 eyadlulayo, utshilo umongameli weProAmpac. Iplastiki ikwasendleleni yokukhuselwa kwendalo, ngokwemveliso yezinto eziluhlaza, ngoko ke ukukhuselwa kwendalo kweplastiki kunokwahlulwahlulwa kubeiiplastiki ezisetyenzisiweyo, iiplastiki ezibolayo, iiplastiki ezityiwayo.
- Iiplastiki ezisetyenzisiweyoibhekisa kwizixhobo zeplastiki ezifunyenwe kwakhona emva kokucutshungulwa kwenkunkuma yeplastiki ngokulungiswa kwangaphambili, ukunyibilika kwe-granulation, ukuguqulwa kunye nezinye iindlela zomzimba okanye zeekhemikhali, ezikukusetyenziswa kwakhona kweplastiki.
- Iiplastiki ezibolayoziiplastiki ezibola lula kwindawo yendalo ngokongeza inani elithile lezongezo (umz. isitashi, isitashi esiguquliweyo okanye enye i-cellulose, ii-photosensitizers, ii-biodegraders, njl.njl.) kwinkqubo yemveliso, ngokunciphisa uzinzo.
- Iiplastiki ezityiwayo, uhlobo lokupakisha okutyiwayo, oko kukuthi, ukupakisha okunokutyiwa, ngokubanzi kwenziwa ngesitatshi, iiproteni, i-polysaccharide, amafutha, kunye nezinto ezidityanisiweyo.
Ngaba ukupakishwa kwephepha kunobuhlobo nokusingqongileyo?
Ukutshintsha iingxowa zeplastiki ngeengxowa zephepha kuthetha ukwanda kokutshatyalaliswa kwamahlathi, nto leyo eya kuba kukubuyela kwiindlela zakudala zokutshatyalaliswa kwamahlathi ngokugqithisileyo. Ukongeza ekutshatyalalisweni kwemithi, ukungcola kwamaphepha kulula ukunganakwa, eneneni, ukungcola kwamaphepha kunokuba ngaphezulu kokwenziwa kweplastiki.
Ngokweengxelo zeendaba, ukwenziwa kwephepha kwahlulwe ngamanyathelo amabini: ukukhupha amanzi kunye nokwenza iphepha, kwaye ungcoliseko luvela kakhulu kwinkqubo yokukhupha amanzi. Okwangoku, uninzi lweefektri zephepha zisebenzisa indlela ye-alkaline yokukhupha amanzi, kwaye kwitoni nganye ye-pulp eveliswayo, malunga neetoni ezisixhenxe zamanzi amnyama ziya kukhutshwa, nto leyo engcolisa kakhulu unikezelo lwamanzi.
Eyona ndlela ibalaseleyo yokukhusela indalo kukunciphisa ukusetyenziswa okanye ukuphinda kusetyenziswe
Imveliso nokusetyenziswa kwezinto ezilahlwayo yeyona ngxaki inkulu yongcoliseko, ukwala "izinto ezilahlwayo", ukusetyenziswa kwakhona kuyanceda kwindalo esingqongileyo. Kucacile ukuba sonke kufuneka sithathe inyathelo lokunciphisa impembelelo yethu kwindalo esingqongileyo. Ukunciphisa, ukusebenzisa kwakhona kunye nokuphinda usebenzise zizinto ezilahlwayo ziindlela ezilungileyo zokunceda ukukhusela indalo esingqongileyo namhlanje. Ishishini lezinto zokuthambisa likwajonge ekupakisheni okuzinzileyo okunciphisa, kuphinda kusetyenziswe kwaye kusetyenziswe kwakhona.
