Lokhu kukunikeza ukuqonda okujulile ngezikhwama zokupakisha ezibolayo!
Njengoba amazwe amaningi evimbela izikhwama zepulasitiki, izikhwama ezibolayo ziyasetshenziswa ezimbonini eziningi. Ukuvikela imvelo kuyindlela engenakugwenywa. Ingabe ikhona imithombo encoma ukusebenzisa izikhwama zepulasitiki ezibolayo? Yimiphi imikhiqizo izikhwama zepulasitiki ezibolayo ezingasetshenziswa kuyo? Ngikholwa ukuthi yilokhu amakhasimende amaningi a-oda izidingo zezikhwama zepulasitiki ezibolayo ngokuphelele afuna ukukwazi. Namuhla, OK Ukupakishwa kokukhiqizwa kwezikhwama zepulasitiki ezibolayo
1. Kuyini ukupakisha okubolayo?
Isikhwama sepulasitiki esibolayo uhlobo lwesikhwama sepulasitiki esingabola ngokuphelele amanzi, i-carbon dioxide kanye namanye ama-molecule amancane. Umthombo oyinhloko walesi sici esibolayo yi-polylactic acid (PLA), ekhishwa kummbila kanye ne-cassava. I-Planet (PLA) uhlobo olusha lwezinto ezisekelwe ku-bio kanye nezinto ezibolayo ezivuselelekayo. Ngemva kokubiliswa kwe-glucose kanye nezinye izinhlobo ukuze kukhiqizwe i-lactic acid emsulwa kakhulu, i-poly (lactic acid) enesisindo esithile sama-molecule yakhiwa ngendlela yokwenziwa kwamakhemikhali, bese i-glucose itholakala nge-saccharification. Lo mkhiqizo unokubola okuhle futhi ungabola ngokuphelele yizinto ezincane zemvelo ngemva kokusetshenziswa ukukhiqiza i-carbon dioxide namanzi, okungeke kungcolise imvelo ngemva kokusetshenziswa. Kuwusizo kakhulu ekuvikelweni kwemvelo futhi kubhekwa njengento enobungani nemvelo.
Njengamanje, izinto eziyinhloko zebhayoloji zezikhwama zepulasitiki ezibolayo zakhiwe yi-PLA + PBAT, engabola ngokuphelele ibe ngamanzi kanye ne-carbon dioxide ezinyangeni ezi-3-6 ngaphansi kwesimo sokufaka umquba (ama-degree angu-60-70). Akukho ukungcola emvelweni. Kungani kungezwa i-PBAT? I-PBAT iyi-copolymer ye-adipic acid, i-1, i-4-butanediol kanye ne-terephthalic acid, okuyi-polymer ebola ngokuphelele eyenziwe ngamakhemikhali nephunga. I-PBAT inokuguquguquka okuhle kakhulu futhi ingasetshenziswa ekukhipheni ifilimu, ekubumbeni okubhujiswayo, ekumbozeni okuphumayo kanye nezinye izinqubo zokubumba. Ukuhlanganiswa kwe-PLA kanye ne-PBAT kuklanyelwe ukuthuthukisa ukuqina, ukubola kanye nokwakheka kwe-PLA.
2. Baphi abakhiqizi bezikhwama ezibolayo abanedumela elihle?
Emkhakheni wezikhwama zepulasitiki ezibolayo, yenze umshini okhethekile wokufutha ifilimu, umshini wokunyathelisa, umshini wokusika izikhwama, i-granulator yokuvuselela imfucuza kanye nemigqa ehlukahlukene yokukhiqiza evuthiwe yezikhwama zepulasitiki ezibolayo. Imikhiqizo ihlanganisa izikhwama zevesti, izikhwama zikadoti, izikhwama zezandla, izikhwama zezingubo, izikhwama zehadiwe, izikhwama zezimonyo, izikhwama zokudla, izikhwama zekhanda lamakhadi, izikhwama ze-kraft paper /PLA composite, njll., ikhwalithi ezinzile, ukusebenza kahle kokukhiqiza okuphezulu, ukuphrinta okuhle kakhulu, ukumelana nomswakama, ukumelana nokubhoboza, okungenabo ubuthi, ukuvala okuhle, ukwelula okuhle, ukuthungwa okuhle, ukuvikelwa kwemvelo.
Ukupakisha kwe-OK kunamathela emcabangweni wokuvikelwa kwemvelo futhi kuzibophezele ekuthuthukisweni okusimeme kwemvelo, kuthuthukiswe ngempumelelo kufanelekile embonini yokupakisha kanye nokupheka, kunikeza izinto ezigcwele ezibolayo kanye nemikhiqizo, kunolwazi olucebile embonini yokupakisha futhi kusabela ekuhlukanisweni kwemfucuza, kukhuthaze ukusetshenziswa kabusha kwezinsizakusebenza, futhi kuthuthukiswe ngenkuthalo imikhiqizo egcwele ebolayo esezingeni lokudla.
3. Yimiphi imikhiqizo izikhwama ezibolayo ezingasetshenziswa kuyo?
Izikhwama zepulasitiki ezibolayo zisetshenziswa kabanzi ehembeni, ekuthungeni, ezingutsheni, ezingutsheni, ezindwangu, ekudleni, kwihadiwe, kuma-elekthronikhi, ezimonyweni nakwezinye izimboni. Izikhwama zepulasitiki ezibolayo zinemiklamo eminingi yokuvala, njengethambo lokunamathela, uziphu, itheyiphu, njll., kanti izikhwama zepulasitiki ezibolayo zihlanganiswa nephepha, elingagoqa isitho esingezansi. Manje, izikhwama zepulasitiki ezibolayo zingena kuzo zonke izindlela zokuphila, futhi kunezindlela ezahlukahlukene; Esikhathini esizayo, izikhwama zepulasitiki ezibolayo zizoba umkhiqizo ophelele embonini yokupakisha.
