Iindaba

Kwimeko yefilimu ye-documentary "uBukhosi beplastiki", kwelinye icala, kukho iintaba zenkunkuma yeplastiki eChina;Kwelinye icala, oosomashishini baseTshayina bahlala bengenisa iiplastiki zenkunkuma.Kutheni ungenisa iiplastiki zenkunkuma ezivela phesheya kolwandle?Kutheni le nto "inkunkuma emhlophe" ehlala ibonwa yiTshayina ingaphinda isetyenziswe?Ngaba ngenene iyoyikisa ngolo hlobo ukungenisa ngaphandle iiplastiki ezilahlwayo?Okulandelayo, masihlalutye kwaye siphendule.Igranulator yeplastiki

Iiplastiki zenkunkuma, isitshixo kukubhekisa kwizinto ezishiyekileyo kwinkqubo yokuvelisa iplastiki kunye nezinto ezityumkileyo zeemveliso zeplastiki ezilahlwayo emva kokuphinda zisetyenziswe.Uninzi lweemveliso zeplastiki ezisetyenzisiweyo, ezinje ngee-casings zobunjineli be-electromechanical, iibhotile zeplastiki, iiCD, imigqomo yeplastiki, iibhokisi zeplastiki, njl.Iiparamitha zokusebenza zezinye iiplastiki zenkunkuma zingcono nangaphezulu kunezo zotyatyazo jikelele ezichasene nomhlwa.

1, Ukurisayikilisha, zininzi eziqhele ukusetyenziswa (igranulator yeplastiki)
Emva kokurisayikilishwa, inkunkuma yeplastiki inokwenziwa kwezinye izinto ezininzi, ezinje ngeengxowa zeplastiki, imigqomo yeplastiki, kunye nezinye iimveliso zeplastiki zemihla ngemihla.Kufuneka kuphela ukutshintsha ezinye iimpawu zeplastiki yoqobo kunye nokusetyenziswa kweplastiki entsha, engahambelani kuphela nexabiso eliphezulu lezinto eziphilayo zeplastiki, kodwa inxulumene nemveliso kunye nokhuseleko lweplastiki ngokutsho iimpawu ze-alloy yentsimbi yokuqala.

I-2, iChina ifuna, iimfuno kodwa akwanelanga
Njengelizwe elivelisa iplastiki kunye nelizwe elityayo emhlabeni, iChina ivelise kwaye yenza i-1/4 yeeplastiki zehlabathi ukususela ngo-2010, kwaye ukusetyenziswa kwe-akhawunti ye-1 / 3 yemveliso yehlabathi.Kwanangonyaka ka-2014, xa ukuphuculwa kwemveliso yeplastiki kuphuculwe kancinci kancinci, ukuveliswa kwemveliso yeplastiki yaseTshayina kwaba 7.388 yezigidi zeetoni, ngelixa ukusetyenziswa kweTshayina kwafikelela kwi-9.325 yezigidi zeetoni, ukwanda kwe-22% kunye ne-16% ngokulandelelanayo ngo-2010.
Imfuno enkulu yenza ukuba izinto zeplastiki zibe ziimveliso eziyimfuneko ezinomlinganiselo omkhulu weshishini.Imveliso kunye nokuveliswa kwayo kuvela ekusetyenzisweni kwakhona, ukuveliswa kunye nokulungiswa kweeplastiki zenkunkuma.Ngokwengxelo yohlalutyo yemveliso yamandla ahlaziyekayo kunye nemveliso yombane yaseTshayina ekhutshwe liSebe lezoRhwebo, ngo-2014 yayiyeyona mali iphezulu yenkunkuma esetyenzisiweyo kwilizwe lonke, kodwa yayiziitoni ezizigidi ezingama-20 kuphela, ezibalelwa kwi-22% yokusetyenziswa koqobo. .
Ukungeniswa kweeplastiki zenkunkuma ezivela phesheya azikho ngaphantsi kwexabiso lempahla ekrwada yeplastiki, kodwa kwakhona isitshixo kukuba iiplastiki ezininzi zenkunkuma zisenako ukugcina imveliso emihle kakhulu kunye neempawu zokucubungula kunye namaxabiso esalathisi semichiza ephilayo emva kokusonjululwa.Ukongeza, irhafu yokungenisa kunye neendleko zokuthutha ziphantsi, ngoko ke kukho indawo ethile yenzuzo kwimveliso yaseChina kunye nemarike yokucubungula.Kwangaxeshanye, iiplastiki ezisetyenzisiweyo kwakhona zinemfuno enkulu yentengiso eTshayina.Ke ngoko, ngokunyuka kwexabiso lezinto zokugquma ezinqanda ukubola, ziya zisanda iinkampani ezingenisa iiplastiki zenkunkuma ukuze zilawule iindleko.

Kutheni le nto "inkunkuma emhlophe" ehlala ibonwa yiTshayina ingaphinda isetyenziswe?
Iiplastiki zenkunkuma luhlobo lobutyebi, kodwa kuphela iiplastiki zenkunkuma ezicociweyo zingaphinda zisetyenziswe ngamaxesha amaninzi, okanye zisetyenziswe kwakhona kwigranulation, ukucocwa, ukwenza ipeyinti, izinto zokwakha zokuhombisa, njl. Kweli nqanaba, nangona iiplastiki zenkunkuma sele zineentlobo ezahlukeneyo. usetyenziso oluphambili, alunasandi kakhulu kwitekhnoloji yokuphinda isetyenziswe, ukuhlolwa kunye nesisombululo.Ukurisayikilishwa okwesibini kweeplastiki ezilahlwayo kufuneka kube lixesha kunye neendleko, kwaye nomgangatho wemathiriyeli ekrwada eveliswayo yaze yalungiswa nayo inzima kakhulu.
Ke ngoko, uphando kunye nophuhliso lwezixhobo zemveliso ezigqwesileyo kunye nobuchwephesha bokusetyenziswa ngokubanzi ukukhuthaza ukusetyenziswa kwakhona kwenkunkuma yeplastiki ukufezekisa unyango olungenabungozi kunye nokusetyenziswa okunengqiqo luncedo lobugcisa ukunciphisa ungcoliseko lomoya;Ukuqulunqwa nokusetyenziswa kwemithetho nemigaqo yokuhlelwa kwenkunkuma, ukurisayikilishwa nokusetyenziswa kwayo yeyona nto ifunekayo kulungiso olusengqiqweni "lwenkunkuma emhlophe".

3, Thembela kwimithombo yangaphandle ukugcina amandla
Ukungeniswa kweeplastiki zenkunkuma kunye nokuphinda kusetyenziswe kunye nokuhlanjululwa kweeplastiki zenkunkuma akunakunciphisa kuphela ukuphikisana phakathi kokunikezelwa kunye nemfuno yempahla ekrwada yeplastiki, kodwa nokugcina utshintshiselwano oluninzi lwangaphandle lweoli yaseChina evela kumazwe angaphandle.Izinto ezikrwada zeplastiki yioyile ekrwada, kwaye imithombo yamalahle yaseTshayina ilinganiselwe.Ukungenisa ngaphandle iiplastiki zenkunkuma kunokunciphisa ingxaki yokunqongophala kwezixhobo eChina.
Ngokomzekelo, iibhotile ze-coke kunye ne-Aquarius zeplastiki, ezinokulahlwa ngokulula, zingumthombo wamaminerali omkhulu kakhulu ukuba zihlaziywa kwaye zibekwe kwindawo enye.Itoni yenkunkuma yeplastiki inokuvelisa i-600kg yepetroli yesithuthi kunye ne-injini ye-diesel, egcina izibonelelo kakhulu.
Ngokunyuka kokunqongophala kwemithombo yendalo kunye nokunyuka okuqhubekayo kwamaxabiso ezinto eziphathekayo, ukuveliswa kunye nokuveliswa kwemathiriyeli ekrwada yesibini kuya kuxhalabisa kakhulu ngabavelisi kunye nabaqhubi.Ukusebenzisa iiplastiki ezihlaziyiweyo ukwenza imveliso kunye nemveliso kunokuphucula ngokufanelekileyo ukukhuphisana kwabavelisi bemizi-mveliso kunye nabaqhubi abavela kwiinkalo ezimbini zophuhliso loqoqosho kunye nokukhuselwa kokusingqongileyo.Xa kuthelekiswa neeplastiki ezintsha, ukusebenzisa iiplastiki ezihlaziyiweyo njengezinto ezisetyenziswayo ukwenza imveliso kunye nokuvelisa kunokunciphisa ukusetyenziswa kwamandla nge-80% ukuya kwi-90%.
