Ngokwethulwa koHlelo Lweminyaka Eyishumi Nambili, uhlelo lwezwe lami lokuthuthela emadolobheni luzokhula ngesivinini unyaka nonyaka. Njalo ngo-1% ukwanda kokuya emadolobheni kuzodinga ama-cubic metres angu-3.2 billion wokusetshenziswa kwamanzi emadolobheni. Ngakho-ke, ukukhishwa kwamapayipi epulasitiki kusalindeleke ukuthi kugcinwe isilinganiso sesilinganiso sonyaka sika-15%. Izinga lokukhula elihlanganisiwe cishe ngo-%.

Amapayipi epulasitiki aseChina asethuthuke aba yisigaba esibalulekile semikhiqizo yepulasitiki. Izinto zokwakha zamakhemikhali ziwuhlobo lwesine lwezinto zokwakha ezintsha ezivela ezikhathini zamanje ngemva kwensimbi, ukhuni, nosimende. Amapayipi epulasitiki, amaphrofayili epulasitiki, iminyango namafasitela yizinhlobo ezimbili eziyinhloko zezinto zokwakha zamakhemikhali ezisetshenziswa kaningi. Kusukela ngo-1994, uhulumeni waseShayina uhlelwe ngokuhlanganyela uMnyango Wezokwakha, uMnyango Wemboni Yamakhemikhali wangaphambili, i-China National Light Industry Council, iNational Building Materials Bureau, kanye ne-China Petrochemical Corporation yangaphambili ukuze bahlele ngokubambisana "I-National Chemical Industry Council. I-Building Materials Coordination Leading Group” ukwakha nokushicilela imizamo efanele. Ukuthuthukiswa kwezinto ezihlosiwe zokwakha amakhemikhali, amapulani, izinqubomgomo, amazinga, njll. Eminyakeni embalwa nje, amapayipi epulasitiki aseChina, amaphrofayili, iminyango namafasitela azuze intuthuko esheshayo. Umthamo kazwelonke wokukhiqiza wamapayipi epulasitiki ngo-1994 wawungamathani angu-240,000, kanti umphumela wawuyi-150,000 Ngo-2000, umthamo wawungamathani ayizigidi ezingu-1.64, futhi umphumela wawungamathani ayizigidi ezingu-1 (okuphuma kuwo amapayipi e-PVC-U ayengamathani angama-500,000) , umugqa wokukhiqiza amapayipi usufinyelele ngaphezu kwe-2,000, futhi isilinganiso esikhulu sokukhiqiza samapayipi e-polyvinyl chloride aqinile singaphezu kwamathani ayi-10,000. Kunamabhizinisi angaphezu kwama-30 ezweni lonke.

Amanethiwekhi amapayipi endabuko ikakhulukazi amapayipi ensimbi, amapayipi ensimbi, amapayipi kasimende namapayipi obumba. Izinto zamapayipi endabuko ngokuvamile zinezici zokusetshenziswa kwamandla aphezulu kanye nokungcoliswa kwemvelo. Ngesikhathi esifanayo, inethiwekhi yamapayipi inamaphutha alandelayo: ① Impilo yesevisi emfushane, ngokuvamile iminyaka engu-5-10; ②Ukungazweli kahle kwamakhemikhali nokumelana nokugqwala; ③Ukungasebenzi kahle kwe-hydraulic; ④Izindleko zokwakha eziphezulu, isikhathi eside; ⑤Ubuqotho bepayipi elibi, ukuvuza kalula, njll. Kusukela maphakathi nekhulu lama-20, amazwe emhlabeni jikelele, ikakhulukazi amazwe athuthukile, abelokhu enza izinto ezikhethekile zamapayipi epulasitiki nokusebenzisa amapayipi epulasitiki.

Eminyakeni eyishumi edlule, amapayipi epulasitiki athuthuke ngokushesha. Amapayipi epulasitiki aya ngokuya ethandwa kakhulu ngokuvikelwa kwawo kwemvelo kanye nokuphepha ekuphileni kwansuku zonke kanye nezicelo zezimboni, futhi adlala indima ebalulekile nengenakushintshwa. Ikakhulukazi embonini yezokwakha, amapayipi epulasitiki awakwazi nje ukufaka esikhundleni sensimbi, izinkuni, nezinto zokwakha zendabuko ngenani elikhulu, kodwa futhi abe nezinzuzo zokonga amandla, ukonga izinto ezibonakalayo, ukuvikelwa kwemvelo, ukuthuthukiswa kwendawo ephilayo, ukuthuthukiswa komsebenzi wokwakha. kanye nekhwalithi, ukuncishiswa kwesisindo sokwakha, kanye nokuqedwa okulula. , Isetshenziswa kabanzi ekwakheni amanzi kanye ne-drainage, ukuhlinzekwa kwamanzi emadolobheni kanye ne-drainage, amapayipi egesi kanye nezinye izinkambu; izinga lokukhula kwamapayipi epulasitiki cishe izikhathi ezi-4 izinga lokukhula elijwayelekile lamapayipi, eliphakeme kakhulu kunezinga lokukhula komnotho wezwe lamazwe ahlukahlukene. Ukushintsha amapayipi ensimbi asakazwayo namapayipi ensimbi ngamapayipi aluhlaza alungele imvelo sekuphenduke inkambiso yentuthuko kuleli khulu leminyaka elisha. Amapayipi epulasitiki athuthukiswe ngempumelelo futhi asetshenziswa kabanzi emazweni athuthukile, ikakhulukazi eYurophu; intuthuko ezweni lami ibilokhu ibambezeleka uma kuqhathaniswa, kodwa eminyakeni yamuva nje, ngokuthuthukisa amandla ezwe lami aphelele kanye nokuthuthukiswa kwezinga lokuphila kwabantu, amapayipi epulasitiki enze inqubekelaphambili ngokushesha. ukuthuthukiswa kwe.

Izinhlobonhlobo kanye nokusetshenziswa kwamapayipi epulasitiki kuye kwathuthuka ngokushesha eminyakeni embalwa edlule. Njengamanje, amapayipi epulasitiki ezwe lami athuthukile aba imboni yezinto zokwakha enezinhlobonhlobo eziphelele kanye namandla amakhulu okukhiqiza. Izinhlobo eziyinhloko zamapayipi epulasitiki yilezi: amapayipi e-UPVC,Amapayipi e-CPVC, namapayipi e-PE. , ipayipi le-PAP, ipayipi le-PE-X, ipayipi le-PP-B,Ipayipi le-PP-R, ipayipi le-PB, ipayipi le-ABS,ipayipi eliyinhlanganisela yensimbi-plastiki, ingilazi fibre reinforced pipe, njll. Isetshenziswa kabanzi kumapayipi okuphakela amanzi nasemapayipini okukhipha amanzi ukuze kwakhiwe, amapayipi amanzi agqitshwe emadolobheni, amapayipi amanzi, amapayipi egesi, amapayipi amanzi kanye namapayipi okudonsa amanzi ezindaweni zasemakhaya, amapayipi okunisela, kanye nendle yezimboni kanye ukuthuthwa kwamanzi amakhemikhali, njll., ukuhlangabezana nezidingo zemikhakha ehlukahlukene yomnotho wezwe. Izidingo ezahlukene zamapayipi. Kufanele sithuthukise futhi sikhiqize uhlobo oluthile lwamapayipi epulasitiki ngokusho kwezimpawu kanye nokusetshenziswa kwamapayipi ahlukahlukene.
