Isingeniso
Ipulasitiki ewohlokayo ibhekisela ohlotsheni lwepulasitiki impahla yalo engahlangabezana nezidingo zokusetshenziswa, ukusebenza kwayo kuhlala kungashintshile phakathi nenkathi yokulondoloza, futhi kungacekelwa phansi kube yizinto ezingavumelani nemvelo ngaphansi kwezimo zemvelo zemvelo ngemva kokusetshenziswa.Ngakho-ke, yaziwa nangokuthi ipulasitiki eyonakaliswa imvelo.
Kunezinhlobonhlobo zamapulasitiki amasha: amapulasitiki abolayo isithombe, amapulasitiki angaboli, isithombe/i-oxidation/ipulasitiki ebolayo, amapulasitiki abolayo asuselwa ku-carbon dioxide, amapulasitiki abolayo wesitashi se-thermoplastic.
Ukuwohloka kwe-polymer kubhekisela enqubweni yokwephula uchungechunge lwe-macromolecular ye-polymerization ebangelwa izici zamakhemikhali nezomzimba.Inqubo yokuwohloka lapho ama-polymer echayeka khona ezimweni zemvelo ezifana nomoya-mpilo, amanzi, imisebe, amakhemikhali, ukungcola, amandla emishini, izinambuzane nezinye izilwane, kanye nama-microorganisms kubizwa ngokuthi ukucekelwa phansi kwemvelo.Ukuwohloka kunciphisa isisindo samangqamuzana e-polymer futhi kunciphisa izakhiwo ezibonakalayo ze-polymer material kuze kube yilapho impahla ye-polymer ilahlekelwa ukusebenziseka kwayo, into eyaziwa nangokuthi ukuwohloka kokuguga kwezinto ze-polymer.
Ukuwohloka kokuguga kwama-polymers kuhlobene ngokuqondile nokuzinza kwama-polymers.Ukuwohloka kokuguga kwama-polymers kunciphisa impilo yesevisi yamapulasitiki.
Selokhu kwavela amapulasitiki, ososayensi bazibophezele ekulweni nokuguga kwezinto ezinjalo, okungukuthi, ukutadisha ukuzinza, ukuze kukhiqizwe izinto ezizinzile ze-polymer, futhi ososayensi emazweni ahlukahlukene basebenzisa ukuziphatha kokuguga kwe-polymer. ama-polymers ukuthuthukisa amapulasitiki okucekelwa phansi kwemvelo.
Izindawo eziyinhloko zokusetshenziswa kwamapulasitiki awonakele yilezi: ifilimu ye-mulch yezolimo, izinhlobo ezahlukene zezikhwama zokupakisha zepulasitiki, izikhwama zikadoti, izikhwama zokuthenga ezitolo ezinkulu kanye nezitsha zokudla ezilahlwayo.
Umqondo Wokwehliswa
Inqubo yokuwohloka kwamapulasitiki awonakaliswa imvelo ikakhulukazi ihilela ukuwohloka kwemvelo, ukuwohloka kwezithombe kanye nokuwohloka kwamakhemikhali, futhi lezi zinqubo ezintathu eziyinhloko zokuwohloka zinemiphumela ehambisanayo, ehambisanayo nehambisanayo komunye nomunye.Isibonelo, ukuwohloka kwezithombe kanye nokuwohloka kwe-oxide kuvame ukuqhubeka kanyekanye futhi kuthuthukiswe;I-Biodegradation cishe ingenzeka ngemva kwenqubo ye-photodegradation.
Ikusasa Trend
Isidingo samapulastiki owonakalayo kulindeleke ukuthi sikhule ngokuqhubekayo, futhi kancane kancane singene esikhundleni semikhiqizo eminingi eyenziwe ngepulasitiki yendabuko.
Kunezizathu ezimbili ezinkulu eziholela kulokhu, 1) Ukwanda kokuqwashisa komphakathi ngokuvikelwa kwemvelo kugqugquzela abantu abaningi ukuthi bazijwayeze nomkhiqizo ovumela imvelo.2) Ukuthuthukiswa kobuchwepheshe kwehlisa izindleko zokukhiqiza imikhiqizo yepulasitiki ebolayo.Kodwa-ke, izindleko eziphezulu zama-resin awonakele kanye nokusebenza okuqinile kwemakethe yawo ngamapulasitiki ahlukahlukene asevele ekhona kwenza kube nzima ukuthi amapulasitiki abolayo angene emakethe.Ngakho-ke, ipulasitiki ebolayo ngeke ikwazi ukufaka esikhundleni sepulasitiki yendabuko ngesikhathi esifushane.
Umshwana wokuzihlangula: yonke idatha kanye nolwazi olutholwe nge-Ecopro Manufacturing Co., Ltd okuhlanganisa kodwa kungagcini ngokufaneleka kwezinto, izakhiwo zezinto ezibonakalayo, ukusebenza, izici nezindleko kunikezwe ngenjongo yolwazi kuphela.Akufanele kuthathwe njengokucaciswa okubophayo.Ukunqunywa kokufaneleka kwalolu lwazi kunoma yikuphi ukusetshenziswa kuyisibopho somsebenzisi kuphela.Ngaphambi kokusebenza nganoma iyiphi into, abasebenzisi kufanele bathinte abahlinzeki bezinto ezibonakalayo, i-ejensi kahulumeni, noma i-ejensi yezitifiketi ukuze bathole ulwazi oluqondile, oluphelele nonemininingwane mayelana nezinto abazicabangelayo.Ingxenye yedatha nolwazi lwenziwe igeneric ngokusekelwe ezincwadini zezentengiso ezinikezwa abahlinzeki be-polymer kanti ezinye izingxenye zivela ekuhlolweni kochwepheshe bethu.
