Nekutangwa kweChirongwa cheMakore Mashanu cheGumi nembiri, maitiro ekukura kwemaguta munyika yangu achakurumidza gore negore. Kuwedzera kwega kwega kwe1% mukukura kwemaguta kunoda mvura inoshandiswa inosvika mabhiriyoni 3.2 emamita emumaguta. Nokudaro, kubuda kwemapombi epurasitiki kunotarisirwa kuchengetedza avhareji yegore negore ye15%. Kukura kwakabatana kweinenge %.

Mapombi epurasitiki eChina akura kuita chikamu chakakosha chezvigadzirwa zvepurasitiki. Zvinhu zvekuvaka zvemakemikari ndiwo rudzi rwechina rwezvinhu zvitsva zvekuvaka zviri kubuda munguva dzazvino mushure mesimbi, huni, nesimende. Mapombi epurasitiki, maprofile epurasitiki, magonhi nemahwindo ndiwo marudzi maviri makuru ezvigadzirwa zvekuvaka zvemakemikari zvinoshandiswa kakawanda. Kubva muna 1994, hurumende yeChina yave ichirongwa pamwe chete neBazi reKuvaka, iro raimbova Bazi reMaindasitiri eMakemikari, iro raimbova Bazi reChina National Light Industry, National Building Materials Bureau, uye raimbova Bazi reChina Petrochemical Corporation kuronga pamwe chete "Boka Rinotungamira Kurongeka kweZvinhu zveMakemikari zveKugadzira" kuti vagadzire uye vaburitse mabasa akakodzera. Kugadzirwa kwezvinhu zvekuvaka zvemakemikari zvinangwa, zvirongwa, mitemo, zviyero, nezvimwewo. Mumakore mashoma chete, mapaipi epurasitiki eChina, maprofile, magonhi nemahwindo zvakabudirira nekukurumidza. Kugona kwekugadzira mapaipi epurasitiki munyika yose muna 1994 kwaive matani 240,000, uye kubuda kwacho kwaive 150,000. Muna 2000, kugona kwacho kwaive matani mamiriyoni 1.64, uye kubuda kwacho kwaive matani miriyoni imwe (ayo aibuda nemapaipi ePVC-U kwaive matani angangoita 500,000), mutsetse wekugadzira mapaipi wasvika anopfuura 2,000, uye huwandu hukuru hwekugadzira mapaipi epolyvinyl chloride akaoma hunodarika matani zviuru gumi. Kune mabhizinesi anopfuura makumi matatu munyika yese.

Mapombi echinyakare anowanzova mapaipi esimbi, mapaipi esimbi akakandwa, mapaipi esimende nemapombi evhu. Zvinhu zvepaipi zvechinyakare zvinowanzova neunhu hwekushandisa simba rakawanda uye kusvibiswa kwezvakatipoteredza. Panguva imwe chete, mapombi anewo zvikanganiso zvinotevera: ① Hupenyu hupfupi hwebasa, kazhinji makore 5-10; ②Kusagona makemikari zvakanaka uye kuramba ngura; ③Kushanda zvisina kunaka kwehydraulic; ④Mari yakawanda yekuvaka, nguva yakareba; ⑤Kusagona zvakanaka kwepombi, nyore kudonhedza mvura, nezvimwewo. Kubva pakati pezana remakore rechi20, nyika pasi rose, kunyanya nyika dzakabudirira, dzave dzichigadzira zvinhu zvakakosha zvepaipi dzepurasitiki uye kushandisa mapaipi epurasitiki.

Mumakore gumi apfuura, mapaipi epurasitiki akakura nekukurumidza. Mapaipi epurasitiki ari kuramba achizivikanwa nekuda kwekuchengetedzwa kwezvakatipoteredza uye kuchengetedzeka muhupenyu hwezuva nezuva uye mumaindasitiri, uye anoita basa rakakosha uye risingatsiviwe. Kunyanya muindasitiri yekuvaka, mapaipi epurasitiki haangogone kutsiva simbi, huni, uye zvinhu zvekuvaka zvechinyakare chete, asiwo ane zvakanakira kuchengetedza simba, kuchengetedza zvinhu, kuchengetedzwa kwezvakatipoteredza, kuvandudzwa kwenzvimbo yekugara, kuvandudzwa kwebasa rekuvaka uye mhando, kudzikiswa kwehuremu hwechivako, uye kupedzwa kuri nyore. , Inoshandiswa zvakanyanya mukuvaka mvura nekuyerera kwemvura, kupihwa kwemvura nemuguta, mapaipi egasi nedzimwe nzvimbo; mwero wekukura kwemapaipi epurasitiki wakapetwa ka4 kupfuura mwero wekukura kwemapaipi, izvo zvakakwirira kupfuura mwero wekukura kwehupfumi hwenyika dzakasiyana siyana. Kutsiva mapaipi esimbi yakakandwa nemapaipi esimbi akagadzika nemapaipi epurasitiki egirini ane hushamwari kune zvakatipoteredza kwave tsika yekukura muzana rino remakore. Mapaipi epurasitiki akagadzirwa zvinobudirira uye anoshandiswa zvakanyanya munyika dzakabudirira, kunyanya muEurope; budiriro munyika yangu yave ichinonoka, asi mumakore achangopfuura, nekuvandudzwa kwesimba renyika yangu rose uye kuvandudzwa kwemararamiro evanhu, mapaipi epurasitiki afambira mberi nekukurumidza.

Mhando dzakasiyana-siyana dzemapaipi epurasitiki dzakakura nekukurumidza mumakore mashoma apfuura. Parizvino, mapaipi epurasitiki enyika yangu akura kuita indasitiri yezvinhu zvekuvaka ine mhando dzakasiyana-siyana uye kugona kukuru kwekugadzira. Mhando huru dzemapaipi epurasitiki ndeidzi: mapaipi eUPVC,Mapaipi eCPVC, uye mapaipi ePE. , pombi yePAP, pombi yePE-X, pombi yePP-B,Pombi yePP-R, Pombi yePB, Pombi yeABS,pombi yesimbi-purasitiki, mapaipi akasimbiswa nefaibha yegirazi, nezvimwewo. Inoshandiswa zvakanyanya mumapaipi emvura nemapaipi emvura ekuvaka, mapaipi emvura akavigwa muguta, mapaipi emvura, mapaipi egasi, mapaipi emvura nemapaipi emvura ekumaruwa, mapaipi ekudiridza, uye kutakurwa kwetsvina yemumaindasitiri nemakemikari, nezvimwewo, zvichizadzisa zvinodiwa neminda yakasiyana-siyana yehupfumi hwenyika. Zvinodiwa zvakasiyana zvemapaipi. Tinofanira kugadzira nekugadzira mhando yakati yemapaipi epurasitiki zvichienderana nehunhu uye mashandisirwo emapaipi akasiyana-siyana.
