Ngokwaziswa kweSicwangciso seMinyaka emiHlanu yeshumi elineSibini, inkqubo yelizwe lam yokufudukela ezidolophini iza kukhula ngokukhawuleza unyaka nonyaka. Rhoqo nge-1% yokwanda kokufudukela ezidolophini kuya kufuna i-3.2 yebhiliyoni ye-cubic metres yokusetyenziswa kwamanzi ezidolophini. Ngoko ke, ukuveliswa kwemibhobho yeplastiki kusalindeleke ukuba kugcinwe umyinge wonyaka we-15%. Izinga lokukhula okudityanisiweyo malunga ne-%.

Imibhobho yeplastiki yaseTshayina iphuhliswe yaba ludidi olubalulekileyo lweemveliso zeplastiki. Izinto zokwakha zemichiza luhlobo lwesine lwezixhobo zokwakha ezitsha ezivela kumaxesha anamhlanje emva kwentsimbi, umthi, nesamente. Imibhobho yePlastiki, iiprofayili zeplastiki, iingcango kunye neefestile zezona ntlobo zimbini zezixhobo zokwakha iikhemikhali ezisetyenziswa rhoqo. Ukusukela ngo-1994, urhulumente waseTshayina uququzelelwe ngokudibeneyo liSebe lezoKwakha, i-Ofisi yoBuphathiswa boShishino lweMichiza, owayesakuba yiKhansile yoShishino lokuKhanya lweSizwe laseTshayina, i-National Building Materials Bureau, kunye ne-China Petrochemical Corporation yangaphambili ukuba iququzelele ngokudibeneyo "iQela eliKhokelayo leSizwe leMichiza yoLwakhiwo lweMathiriyeli" ukuqulunqa nokupapasha iinzame ezifanelekileyo. Ukuphuhliswa kwethagethi zezinto zokwakha iikhemikhali, izicwangciso, imigaqo-nkqubo, imigangatho, njl. Kwiminyaka embalwa nje, imibhobho yeplastiki yaseChina, iiprofayili, iingcango kunye neefestile zifezekise uphuhliso olukhawulezayo. Umthamo wemveliso wesizwe wemibhobho yeplastiki ngo-1994 yaba iitoni ezingama-240,000, kwaye imveliso yayiyi-150,000 ngo-2000, umthamo wawuyi-1.64 yezigidi zeetoni, kwaye imveliso yayiyi-1 yezigidi zeetoni (apho imveliso yemibhobho ye-PVC-U yayimalunga neetoni ezingama-500,000), umbhobho, umbhobho, umgca wemveliso onzima kunye no-0 ufikelele kwi-2000. imibhobho ye-polyvinyl chloride ingaphezulu kweetoni ezili-10,000. Kukho amashishini angaphezu kwama-30 kwilizwe lonke.

Uthungelwano lwemibhobho yesintu ubukhulu becala yimibhobho yentsimbi, imibhobho yentsimbi, imibhobho yesamente nemibhobho yodongwe. Izinto zemibhobho yemveli ngokubanzi zineempawu zokusetyenziswa kwamandla aphezulu kunye nongcoliseko lokusingqongileyo. Kwangaxeshanye, inethiwekhi yombhobho nayo ineziphene zilandelayo: ① Ubomi benkonzo emfutshane, ngokubanzi iminyaka emi-5-10; ②Ukunganyangeki kakuhle kweekhemikhali kunye nokumelana nokubola; ③Ukusebenza kakubi kwehydraulic; ④Ixabiso eliphezulu lokwakha, ixesha elide; ⑤Ukunganyaniseki kwemibhobho, kulula ukuvuza, njl njl. Ukusukela phakathi kwinkulungwane yama-20, amazwe ehlabathi, ngakumbi amazwe aphuhlileyo, aphuhlisa izinto ezikhethekileyo zemibhobho yeplastiki kunye nokusetyenziswa kwemibhobho yeplastiki.

Kwiminyaka elishumi edlulileyo, imibhobho yeplastiki iphuhliswe ngokukhawuleza. Imibhobho yePlastiki iya ithandwa ngakumbi ngokukhusela nokukhuseleka kokusingqongileyo kubomi bemihla ngemihla kunye nezicelo zemizi-mveliso, kwaye zidlala indima ebalulekileyo nengenakubuyiselwa. Ngokukodwa kushishino lokwakha, imibhobho yeplastiki ayinakuthatha indawo yentsimbi kuphela, iinkuni, kunye nezixhobo zokwakha zemveli kwisixa esikhulu, kodwa nazo zineengenelo zokonga amandla, ukugcinwa kwezinto eziphathekayo, ukukhuselwa kwendalo, ukuphuculwa kokusingqongileyo, ukuphuculwa komsebenzi wokwakha kunye nomgangatho, ukuncitshiswa kobunzima bokwakha, kunye nokugqitywa ngokulula. , Ukusetyenziswa ngokubanzi kwisakhiwo sokubonelela ngamanzi kunye nokukhupha amanzi, ukuhanjiswa kwamanzi asezidolophini kunye nokukhupha, imibhobho yegesi kunye nezinye iindawo; izinga lokukhula kwemibhobho yeplastiki malunga namaxesha ama-4 umyinge wokukhula komyinge wemibhobho, ephezulu kakhulu kunezinga lokukhula koqoqosho lwesizwe lwamazwe ahlukeneyo. Ukutshintsha imibhobho yentsimbi kunye nemibhobho yentsimbi efakwe amazimba kunye nemibhobho yeplastiki eluhlaza ehambelana nokusingqongileyo ibe yindlela yophuhliso kwinkulungwane entsha. Imibhobho yeplastiki iphuhliswe ngempumelelo kwaye isetyenziswa ngokubanzi kumazwe aphuhlileyo, ngakumbi eYurophu; uphuhliso lwelizwe lam luluhle kakhulu, kodwa kule minyaka yakutsha nje, ngokwandiswa kwamandla elizwe lam abanzi kunye nokuphuculwa komgangatho wokuphila kwabantu, imibhobho yeplastiki yenze inkqubela ekhawulezileyo. Uphuhliso lwe.

Iindidi kunye nokusetyenziswa kwemibhobho yeplastiki iphuhliswe ngokukhawuleza kwiminyaka embalwa edlulileyo. Okwangoku, imibhobho yeplastiki yelizwe lam iphuhliswe yaba lishishini lezinto zokwakha ezinoluhlu olupheleleyo kunye nomthamo omkhulu wemveliso. Iindidi eziphambili zemibhobho yeplastiki zezi: Imibhobho ye-UPVC,Imibhobho ye-CPVC, kunye nemibhobho ye-PE. , umbhobho wePAP, umbhobho wePE-X, umbhobho wePP-B,Umbhobho wePP-R, umbhobho we-PB, umbhobho we-ABS,umbhobho odibeneyo wentsimbi-yeplastiki, umbhobho weglasi wombhobho wombhobho wonikezelo lwamanzi, njl njl. Isetyenziswa ngokubanzi kwimibhobho yonikezelo lwamanzi kunye nemibhobho yokuhambisa amanzi ekwakhiweni, imibhobho yonikezelo lwamanzi yasezidolophini, imibhobho yokuhambisa amanzi, imibhobho yerhasi, unikezelo lwamanzi kunye nemibhobho yokuhambisa amanzi kwiindawo zasemaphandleni, imibhobho yokunkcenkceshela, kunye nokuhanjiswa kwamanzi amdaka kwimizi-mveliso kunye nemichiza, njl. njl., ukuhlangabezana neemfuno zemimandla eyahlukeneyo yoqoqosho lwesizwe. Iimfuno ezahlukeneyo zemibhobho. Sifanele siphuhlise kwaye sivelise uhlobo oluthile lombhobho weplastiki ngokweempawu kunye nokusetyenziswa kwemibhobho eyahlukeneyo.
