Ngokwaziswa kweSicwangciso seMinyaka emihlanu seShumi elinesibini, inkqubo yokukhula kwezixeko zelizwe lam iya kukhawuleziswa unyaka nonyaka. Ukwanda kwe-1% nganye kokukhula kwezixeko kuya kufuna ukusetyenziswa kwamanzi ezidolophini nge-3.2 yeebhiliyoni zeekhiyubhi. Ke ngoko, imveliso yemibhobho yeplastiki isalindeleke ukuba igcine izinga lonyaka eliphakathi le-15%. Izinga lokukhula elidibeneyo elimalunga ne-%.

Iipayipi zeplastiki zaseTshayina ziye zaphuhliswa zaba ludidi olubalulekileyo lweemveliso zeplastiki. Izixhobo zokwakha zekhemikhali luhlobo lwesine lwezinto zokwakha ezintsha eziphumayo kwixesha langoku emva kwentsimbi, umthi, kunye nesamente. Iipayipi zeplastiki, iiprofayili zeplastiki, iingcango kunye neefestile zezona ntlobo zimbini ziphambili zezinto zokwakha zekhemikhali ezisetyenziswa rhoqo. Ukusukela ngo-1994, urhulumente waseTshayina uququzelelwe ngokubambisana yiSebe lezoKwakha, iSebe langaphambili leMicimbi yeKhemikhali, iBhunga langaphambili leMicimbi yeKhanya yeSizwe yaseTshayina, iZiko leZixhobo zoKwakha leSizwe, kunye neSebe langaphambili lePetrochemical laseTshayina ukuze baququzelele ngokubambisana "iQela eliPhambili leSizwe leMicimbi yoKwakha iKhemikhali" ukuze baqulunqe kwaye bapapashe imizamo efanelekileyo. Uphuhliso lwezinto zokwakha zekhemikhali lujolise, izicwangciso, imigaqo-nkqubo, imigangatho, njl. Kwiminyaka embalwa nje, iipayipi zeplastiki zaseTshayina, iiprofayili, iingcango kunye neefestile ziye zaphuhliswa ngokukhawuleza. Umthamo wesizwe wemveliso yeepayipi zeplastiki ngo-1994 wawuziitoni ezingama-240,000, kwaye imveliso yayiyi-150,000. Ngo-2000, umthamo wawuziitoni ezili-1.64 lezigidi, kwaye imveliso yayiziitoni ezili-1 lesigidi (apho imveliso yeepayipi zePVC-U yayimalunga neetoni ezingama-500,000), umgca wemveliso yeepayipi ufikelele ngaphezulu kwama-2,000, kwaye ubungakanani bemveliso enkulu yeepayipi zepolyvinyl chloride eqinileyo bungaphezulu kweetoni ezili-10,000. Kukho amashishini angaphezu kwama-30 kuzwelonke.

Iinethiwekhi zemibhobho zemveli ikakhulu ziipayipi zentsimbi, iipayipi zesinyithi eziphosiweyo, iipayipi zesamente kunye neepayipi zodongwe. Izixhobo zemibhobho zemveli ngokubanzi zineempawu zokusetyenziswa kwamandla aphezulu kunye nongcoliseko lokusingqongileyo. Kwangaxeshanye, inethiwekhi yemibhobho ikwanazo nezi ntsilelo zilandelayo: ① Ubomi benkonzo obufutshane, ngokubanzi iminyaka emi-5-10; ②Ukuxhathisa kweekhemikhali okubi kunye nokuxhathisa ukugqwala; ③Ukusebenza kakubi kwe-hydraulic; ④Iindleko eziphezulu zokwakha, ixesha elide; ⑤Ukuthembeka okubi kwemibhobho, kulula ukuvuza, njl. Ukusukela phakathi kwenkulungwane yama-20, amazwe kwihlabathi liphela, ingakumbi amazwe aphuhlileyo, ebesenza izixhobo ezikhethekileyo zemibhobho yeplastiki kwaye esebenzisa imibhobho yeplastiki.

Kwiminyaka elishumi edlulileyo, imibhobho yeplastiki iphuhliswe ngokukhawuleza. Imibhobho yeplastiki iya ithandwa ngakumbi ngenxa yokhuseleko lwayo lokusingqongileyo kunye nokhuseleko kubomi bemihla ngemihla kunye nokusetyenziswa kwemizi-mveliso, kwaye idlala indima ebalulekileyo nengenakutshintshwa. Ingakumbi kwishishini lokwakha, imibhobho yeplastiki ayinakuthatha indawo yentsimbi, umthi, kunye nezixhobo zokwakha zemveli kuphela ngobuninzi, kodwa ikwanazo neengenelo zokonga amandla, ukonga izinto, ukhuseleko lwendalo, ukuphuculwa kwendawo yokuhlala, ukuphuculwa komsebenzi wesakhiwo kunye nomgangatho, ukunciphisa ubunzima besakhiwo, kunye nokugqitywa ngokulula. , Isetyenziswa kakhulu ekwakheni unikezelo lwamanzi kunye nokuhambisa amanzi, unikezelo lwamanzi asezidolophini kunye nokuhambisa amanzi, imibhobho yegesi kunye namanye amasimi; izinga lokukhula kwemibhobho yeplastiki liphindwe kane kunezinga lokukhula eliphakathi kwemibhobho, eliphezulu kakhulu kunezinga lokukhula koqoqosho lwesizwe lwamazwe ahlukeneyo. Ukutshintsha imibhobho yesinyithi kunye nemibhobho yentsimbi egalelweyo ngemibhobho yeplastiki eluhlaza enobuhlobo nokusingqongileyo kuye kwaba yindlela yophuhliso kwinkulungwane entsha. Imibhobho yeplastiki iphuhlisiwe ngempumelelo kwaye isetyenziswa kakhulu kumazwe aphuhlileyo, ngakumbi eYurophu; uphuhliso kwilizwe lam belulibazisekile, kodwa kwiminyaka yakutshanje, ngokuphuculwa kwamandla elizwe lam apheleleyo kunye nokuphuculwa kwemigangatho yokuphila yabantu, imibhobho yeplastiki yenze inkqubela phambili ngokukhawuleza.

Iindidi kunye nokusetyenziswa kwemibhobho yeplastiki kuye kwanda ngokukhawuleza kwiminyaka embalwa edlulileyo. Okwangoku, imibhobho yeplastiki yelizwe lam iye yakhula yaba lishishini lezinto zokwakha elineentlobo ngeentlobo ezipheleleyo kunye nomthamo omkhulu wemveliso. Iindidi eziphambili zemibhobho yeplastiki zezi: imibhobho ye-UPVC,Imibhobho yeCPVC, kunye nemibhobho ye-PE. , umbhobho we-PAP, umbhobho we-PE-X, umbhobho we-PP-B,Umbhobho we-PP-R, Umbhobho we-PB, Umbhobho we-ABS,umbhobho odibeneyo wentsimbi-iplastiki, umbhobho oqinisiweyo wefayibha yeglasi, njl. Isetyenziswa kakhulu kwimibhobho yokuhambisa amanzi kunye nemibhobho yokukhupha amanzi yokwakha, imibhobho yokuhambisa amanzi efihliweyo ezidolophini, imibhobho yokukhupha amanzi, imibhobho yegesi, imibhobho yokuhambisa amanzi kunye nemibhobho yokukhupha amanzi kwiindawo zasemaphandleni, imibhobho yokunkcenkceshela, kunye nokuthuthwa kwamanzi amdaka kunye nolwelo lwamakhemikhali kwimizi-mveliso, njl.njl., ukuhlangabezana neemfuno zamacandelo ahlukeneyo oqoqosho lwesizwe. Iimfuno ezahlukeneyo zemibhobho. Kufuneka siphuhlise kwaye sivelise uhlobo oluthile lombhobho weplastiki ngokweempawu kunye nokusetyenziswa kwemibhobho eyahlukeneyo.
