Parizvino, mumapombi emvura uye mapombi emvura, pombi dzepurasitiki dzakatsiva zvishoma nezvishoma pombi dzechinyakare dzakadai sepombi dzesimbi dzakakandwa uye pombi dzesimbi dzakaita kuti dzive mapaipi makuru.Kuenzaniswa nemapombi echinyakare, mapaipi epurasitiki ane mabhenefiti akakosha akadai sehuremu hwehuremu, corrosion resistance, kushomeka kwemvura kuyerera, kuchengetedza simba, nyore uye nekukurumidza kuisa, uye mutengo wakaderera, uye anofarirwa nenharaunda yeinjiniya yepombi.Panguva imwecheteyo, nekukurumidza kukura kweindasitiri yepetrochemical uye kuenderera mberi kwehunyanzvi hwekugadzira epurasitiki, kubuda kwepombi dzepurasitiki kwakawedzera nekukurumidza, uye marudzi ezvigadzirwa ave akasiyana.Uyezve, pombi dzepurasitiki dzakawana budiriro huru nekuvandudzwa kwehunyanzvi hwekugadzira uye tekinoroji yekuvaka mukuvaka, uye yakaunganidza ruzivo rwakapfuma runoshanda, iyo yakasimudzira pombi dzepurasitiki kuti dzitore chinzvimbo chakakosha mukuvaka kwemvura uye yekudhonza pombi engineering, uye kugadzira kusimudzira kusingamisikike. trend.
KuChina, mazhinji emapombi epurasitiki anoshandiswa mumapombi emvura anonyanya kusanganisira PVC-U pombi dzemvura, PP-R mapaipi, aluminium-plastiki composite pombi (PAP), simbi-yepurasitiki composite pombi (SP), HDPE mapaipi, nezvimwe. HDPE pombi yakangoonekwa pamusika mumakumi maviri emakore apfuura.Inotora tekinoroji yekugadzira uye tekinoroji uye inoumbwa nekupisa extrusion.Iyo ine hunhu hwekurambira kwecorrosion, yakatsetseka madziro emukati, yakaderera kuyerera kuramba, kusimba kwepamusoro, kusimba kwakanaka uye huremu huremu.
Mushure mePVC-U pombi yekupa mvura, HDPE pombi yave yechipiri inonyanya kupedzwa pombi yepurasitiki yakasiyana-siyana munyika.Parizvino, pakati kana yakakwira density polyethylene mapaipi ePE80 uye PE100 mamakisi anofanirwa kushandiswa pakufambisa gasi;pakati kana yakakwirira density polyethylene mapaipi ePE80 uye PE100 mamakisi anowanzo shandiswa papombi dzemvura, uye PE63 yakabviswa zvishoma nezvishoma.Panyaya yekuendesa mvura, chiri kukurumidza kukura iPE100 pipeline system, iyo inotarisirwa kukura nezvikamu zvinopfuura gumi kubva muzana mumakore mashanu anotevera.
