Ulwazi oluncedo ngeplastiki

El iplastiki Namhlanje sesinye sezona zixhobo zisetyenzisiweyo kumawaka ezicelo kubomi bemihla ngemihla nakwimizi-mveliso kangangeminyaka eliqela.

Iplastiki yenziwa malunga ne-1860 kodwa ukusetyenziswa kwayo kwaqala nge-1930s.

Iiplastiki zokwenziwa zineempawu ezenze ukuba le nto ithandwe: kuyabiza ukuvelisa, inesisindo esiphantsi, ayinamanzi, iyabhetyebhetye, iyagquma ngombane, iyamelana kwaye iyazivumelanisa nazo zonke iintlobo zokusetyenziswa.

Imveliso yeplastiki iyangcolisa kakhulu ngakumbi xa itshisiwe, ezinye iintlobo zeplastiki kulula ukuzisebenzisa kwakhona kodwa ezinye.

  • Ukusetyenziswa kweeplastiki kwihlabathi ngo-2010 kwakuziitoni ezingama-250 ezigidi kwaye kuyaqhubeka ukwanda.
  • Iiplastiki eziqhelekileyo zithatha phakathi kwe-100, 500 ukuya kuthi ga kwi-1000 iminyaka ukuthoba umgangatho kuxhomekeke kuhlobo lwezixhobo ezisetyenziselwa ukwenziwa kwazo.
  • Ukusetyenziswa kweplastiki kwesiko petroleum kunye neziphumo zokuveliswa kwayo kungcolisa kakhulu, ukongeza kuchithwa okuninzi amandla kwingcaciso yayo.
  • Inkunkuma yeplastiki imele inkunkuma efunyanwa elwandle nakwiilwandle kwihlabathi liphela ngama-60-80%.
  • Kuqikelelwa ukuba i-1 yezigidi zezigidi zeeplastiki zityiwa minyaka le emhlabeni, uninzi lwazo olujika lube yinkunkuma, kuba ingeyiyo inokuphawuleka.
  • Kukho iintlobo ngeentlobo zeplastiki ezisetyenziswa rhoqo kuzo zonke iintlobo zezinto. Ezinye zezona zisetyenziswa kakhulu yiPolystyrene, iPolypropylene, iPolyurethane, iPV, iPET, i-polyamide, phakathi kwabanye.
  • Iiplastikhi zesiko zinokuba noburhabaxa obahlukeneyo, ubunzima kunye nemeko yomzimba kuba inokuba ligwebu, izinto ezilukhuni, ithambile, njl.

Ukuququmbela, iplastiki yayijongwa njengezinto zangoku ezisombulula iingxaki ezahlukeneyo kwaye zinamawaka ezicelo. Kodwa ngokuhamba kwamashumi eminyaka oko kunike izibonelelo kodwa kwavelisa nongcoliseko olukhulu kwaye kwavelisa inkunkuma kuwo wonke umhlaba.

Okwangoku, iiplastikhi zesiko azisajongwa njengezona zinto zibalaseleyo ngenxa yeziphumo zazo kwimpilo yabantu kunye nokusingqongileyo.
