● Empilweni yansuku zonke, inani lezikhwama zepulasitiki likhulu impela, futhi izinhlobo zezikhwama zepulasitiki zihlukahlukene. Imvamisa, akuvamisile ukunaka okubonakalayo kwezikhwama zepulasitiki kanye nomthelela emvelweni ngemuva kokulahlwa. Ngokukhuthaza kancane kancane kwe- "Plast Ban", abathengi abaningi ngokwengeziwe baqale ukunaka izikhwama zepulasitiki ezingokoqobo. Amakhasimende amaningi azoshintshela ezikhwameni zepulasitiki ezingokoqobo, noma ngabe amakhasimende amaningi angawazi umehluko phakathi kwezikhwama zepulasitiki ezijwayelekile, izikhwama zepulasitiki ezicekayo nezikhwama ze-bioderbradable. Ake ngihlanganyele nawe.
Izinhlobo ezintathu zezikhwama zepulasitiki encazelweni, inzuzo kanye nobunzima
Incazelo:
● Izikhwama zepulasitiki ezejwayelekile ezinye izinto zepulasitiki ezifana ne-PE, kanye nengxenye eyinhloko i-resin. I-Resin ibhekisela kwi-polymer compound engaxutshwa nezithasiselo ezahlukahlukene. I-Resin ibeka amaphesenti angaba ngu-40 kuye kwangama-100 wesisindo esiphelele sepulasitiki. Izakhiwo eziyisisekelo zamapulasitiki zinqunywa ikakhulukazi ngohlobo lwe-resin, kepha izengezo nazo zidlala indima ebalulekile. Izikhwama zepulasitiki ze-biodegradable zine-National Environmental Protection Standard GB / T21661-2008, kuyilapho izikhwama zepulasitiki zendabuko zingadingi ukuthobela leli Zinga. Izikhwama zepulasitiki zendabuko zithatha iminyaka engama-200 noma ngaphezulu zingcolisa ngemuva kokulahlwa. Dala "ukungcoliswa okumhlophe" emvelweni.
● Isikhwama sepulasitiki esibonakalayo: ngokweqiniso, kuyisikhwama sepulasitiki esibonakalayo, okusho ukuthi singangcoliswa, kepha sisequkethe izithako zepulasitiki nezinye ezihlobene, kepha zingcolisa ngokugcwele. Kwenziwa ikakhulukazi nge-polyethylene plastiki, ingezwe nge-photodegradant ne-calcium carbonatate namanye ama-powders amaminerali, owaziwa nangokuthi izikhwama zepulasitiki ze-photodegradable. Lolu hlobo lwesikhwama sepulasitiki lubolile ngaphansi kwesenzo sokukhanya kwelanga. Kodwa-ke, i-polyethylene ngemuva kokuvunywa kwe-FEN kusekhona endaweni yemvelo. Yize ukuba khona kokungcoliswa okumhlophe akunakubonwa emgqeni wokubona, ukungcoliswa okumhlophe kusahlasela imvelo yethu ezungezile ngesimo sezinhlayiya ezincane, ezingashiwo ukwelapha izimpawu kodwa hhayi imbangela. Ukubeka nje, ngemuva kokulahla isikhwama sepulasitiki esibonakalayo, usazongcolisa imvelo ngezinga elithile, njengesikhwama sepulasitiki sendabuko. Indawo yayo yokugcina empeleni ifana neyamazinga epulasitiki wendabuko. Ngemuva kokulahlwa, bonke bangena ekulahlekelweni komhlaba noma bayancipha, futhi abanakudilizwa ukudilizwa okukhethekile kwezimboni. Ngakho-ke, "okuwonakalisiwe" kumane nje "kungokonakaliswa", akunakulingana ne- "biodegradadation ephelele". Ngomqondo othile, izikhwama zepulasitiki ezicekayo akusona isixazululo esingenzeka "ekungcoleni okumhlophe", noma "i-panacea" ukuxazulula ukungcoliswa kwesikhwama sepulasitiki. Ngamafuphi, usazokhiqiza imfucuza eningi, nezikhwama zepulasitiki ezingcolile empeleni azizonakaliswa.
● Izikhwama zepulasitiki ze-Biodegradable: Izici ezibonakalayo zezikhwama zepulasitiki ze-biodegradable zakhiwa ngePla (Polyacid) nePbat (Polyadipic Acid). Izinto ezinjalo zihlanganisa i-phas, i-PBA, PBS, njll, ezibonwa njengezinto zokwakha imvelo. Imikhiqizo eluhlaza eluhlaza. I-Biodegradable Plastic Bag Matter, eyaziwa nangokuthi ipulasitiki engathandeki, ibhekisela esenzweni sama-microorganisms akhona emvelweni ngaphansi kwezimo zemvelo ezinjengenhlabathi noma ngaphansi kwezimo zokugaya noma izixazululo ezinamanzi. Kubangela ukonakala, futhi ekugcineni kudicilela phansi ku-carbon dioxide (CO2), i-Methane (CH4), Amanzi (H2O) kanye nosawoti wezinto ezinamamineli wezakhi eziqukethe, kanye namapulasitiki amasha we-biomass.

Izikhwama zepulasitiki ze-biodegramable
Izikhwama zepulasitiki ze-biodegramableyizikhwama ezigcwele eziphelele nezingokonakala. Ngaphansi kwesimo sokuwohloka komquba, kungahle kube khona nge-biodegrad kungakapheli izinsuku ezingama-180. Imikhiqizo yokucekelwa phansi i-carbon dioxide namanzi, angena emhlabathini futhi amunwa izitshalo, abuyele enhlabathini, noma afake imvelo ejwayelekile. Kungonakaliswa ngaphandle kokudala ukungcoliswa kwemvelo, ukuze kuqhamuke endalweni futhi kungokwemvelo. Izikhwama zepulasitiki ze-biodegradable kungashiwo ukuthi zibambile amapulasitiki, anganciphisa kakhulu inkinga yokungcoliswa okumhlophe okubangelwa ukungakwazi kwezikhwama zepulasitiki ezijwayelekile zendabuko ukuxazulula. Kungaxazulula ngokuyisisekelo inkinga yokungcoliswa kwepulasitiki, kunokuba kwelaphe izimpawu. Ukusetshenziswa kwezikhwama zepulasitiki ze-biodegradable kunciphisa kakhulu ukungcoliswa kwemikhiqizo yepulasitiki eya emvelweni. Kuyimvelo enobungani bemvelo, iphilile futhi ihlanzekile, futhi ingasetshenziswa ngokuzethemba. Izikhwama zepulasitiki ze-biodegradable zinokulimala okungcono kunezinye izinto, zisebenzisa isikhathi eside kunezikhwama zamaphepha, futhi zibize izindleko ezingaphansi kwamaphepha.
Landela futhi uxhumane nathi
Ungabona imikhiqizo ehlukene esitolo sethu. Imininingwane eminingi imininingwane Sicela ulandele isitolo sethu, sizovuselela imininingwane kabili ngesonto futhi samukelekile ukuxhumana nathi, sizokuphendula ngokushesha. Ngiyabonga ngokufunda kwakho ~
