Iingxowa zeplastiki zohlulwe zibe ziindidi ezimbini.Enye kukubola iingxowa zokuthenga.Yingxowa yokuthenga ehambelana nokusingqongileyo kwaye ayibangeli naluphi na ungcoliseko kunye nokwenzakala kokusingqongileyo.Iingxowa zokuthenga.Ngenxa yokuba iingxowa zeplastiki ezingenakonakala ziya kubangela umonakalo omkhulu kwindalo, abantu ngoku bakhetha ukusebenzisa iingxowa zokuthenga ezonakeleyo.Ngokubaluleka okukhulayo ekukhuselweni kwendalo, iingxowa zeplastiki ezisetyenziswayo ziya kubangela iingxaki ezinzulu kunye nomthwalo kwindalo.Imfuno yokuthotywa kweengxowa zeplastiki kwixesha elizayo iya kuqhubeka ikhula.
Iplastiki eyonakaliswayo, eyaziwa ngokuba yiplastiki yokutshatyalaliswa kwendalo, ibhekisela kwiplastiki eyongeza inani elithile lezongezo kwinkqubo yokuvelisa ukunciphisa ukuzinza kwayo, kwaye kulula ukuthotywa kwimeko yendalo.Ngophuhliso lwesayensi kunye nethekhnoloji, iintlobo ezahlukeneyo zezixhobo ezinokuthatha indawo yeplastiki ye-PE yemveli ibonakala, kubandakanywa i-PLA, i-PHAS, i-PBA, i-PBS kunye nezinye izinto ze-polymer.Zombini zinokuthatha indawo yeengxowa zeplastiki ze-PE.Iingxowa zeplastiki ezonakaliswayo ezihambelana nokusingqongileyo zisetyenziswa ngokubanzi kungokunje: ezona ndawo zisetyenziswayo ziquka umhlaba wezolimo, iingxowa zokupakisha ezahlukeneyo zeplastiki, iingxowa zenkunkuma, iingxowa zokuthenga kubhazabhaza wevenkile, kunye nezixhobo zokutya ezilahlwayo.
Iplastiki yeBiodegradable ibhekiselele kwiiplastiki ezibangela ukuthotywa kwendima ye-microorganisms efana neebhaktheriya, ukungunda (umngundo) kunye ne-algae ekhoyo kwindalo.Iplastiki efanelekileyo ye-biodegradable iyingxenye yezinto eziphezulu ze-molecular ezinokuchithwa ngokupheleleyo yi-microorganisms yokusingqongileyo emva kokulahlwa, inokuchithwa ngokupheleleyo yi-microorganisms yendalo, kwaye ekugqibeleni ibe yinto engabonakaliyo."Iphepha" yinto eqhelekileyo enokubola, kwaye "iplastiki yokwenziwa" yinto eqhelekileyo yepolymer.Ngoko ke, iplastiki ye-biodegradable yimathiriyeli yepolymer kunye nohlobo "lwephepha" kunye "neplastiki yokwenziwa".Iplastiki enokubola ye-biodegradable inokohlulwa ibe ziindidi ezimbini: iplastiki epheleleyo enokubola kunye neplastiki eyonakalisayo enokonakala
Iplastiki ye-biodegradable eyonakalisayo: Ukutshatyalaliswa kweplastiki ye-biodegradable okwangoku ibandakanya ukuguqulwa kwesitatshi (okanye ukuzaliswa) i-polyethylene PE, i-polypropylene PP, i-polyvinyl chloride PVC, i-polystyrene PS, njl.
Gqibezela iplastiki enokubola: Iplastiki epheleleyo enokubola yenziwa ikakhulu ziipolima zendalo (ezifana nestatshi, icellulose, ichitin) okanye iimveliso zezolimo nezisecaleni.I-Polyester, i-polystrackic acid, isitashi / i-polyvinyl alcohol.
Ukuhlaziywa kwezinto ezikrwada zeengxowa zokuthenga
Ingxowa yeplastiki enokubola ikwabizwa ngokuba ziingxowa zokuthenga ezibolisiweyo.Isebenzisa isitashi sesityalo kunye nomgubo wombona, njl njl. Yenziwe ngezinto ezithathwe kwizityalo.Ezi zixhobo eziluhlaza aziyi kubangela nayiphi na ingozi kumzimba womntu kunye nokusingqongileyo.
Inokunyangwa kumhlaba oneengxowa zokuthenga ezonakeleyo.Kuthatha ixeshana kuphela ukuthotywa libe ngamasuntswana ebhayoloji emva koko afunxelwe ngumhlaba.Ingxowa yeplastiki ebolileyo ayinayo nayiphi na impembelelo kokusingqongileyo, kodwa ingaba sisichumisi sezityalo kunye nezityalo, ukukhuthaza ukukhula kwezityalo.
Ke ngoko, ukusetyenziswa kweengxowa zokuthenga ezonakeleyo ngoku kuyathandwa, kwaye nokusetyenziswa kweengxowa zokuthenga ezingonakali nako kuncipha kancinci.Azikho iingxowa zokuthenga ezinokonakala ziya kubangela ingozi enkulu kwimpilo yabantu kunye nokusingqongileyo kwendalo.
Ukwenzakala kweengxowa zokuthenga ezingonakaliyo
Ngokunxulumene neengxowa zokuthenga ezonakeleyo ziingxowa zokuthenga ezingonakaliyo.Enyanisweni, iingxowa zokuthenga eziqhelekileyo nazo ziyakwazi ukuthotywa, kodwa zithotywe ixesha elide iminyaka engamakhulu amabini.Ngaphezu koko, ukusetyenziswa kweengxowa zeplastiki kuluntu kukhulu kakhulu.Ukuba usebenzisa iingxowa zeplastiki ezingenakubuyiselwa, oko kuya kwenza imekobume yendalo yomhlaba ibe mandundu.
Abantu abanayo indlela ilungileyo yokuseyisa kwakhona inkunkuma yeengxowa zokuthenga, nokuba kukutshiswa okanye ukulahla inkunkuma.Akukho zingxobo zokuthenga ezonakeleyo ziya kuchaphazela okusingqongileyo nokuba yeyiphi na indlela.Ngokomzekelo, ukutshiswa kuya kukhupha iphunga elibi kwaye kuvelise inani elikhulu lomlotha omnyama;ukuba iphathwa ngokulahla inkunkuma, umhlaba uya kuthatha amakhulu eminyaka ukubola ingxowa yeplastiki.
