Kupisa kunyura kwakakurudzira pombi
Tsanangudzo Pfupi
Kupisa dip galvanized pombi, kuitira kuti uvandudze kushomeka kwepombi yesimbi, general simbi pombi inobatiswa.Mapaipi esimbi ane galvanized akakamurwa kuita inopisa-dip galvanizing uye electro galvanizing.Iyo inopisa-dip galvanizing layer yakakora, mutengo we electro galvanizing wakaderera, uye kumusoro hakuna kunyatso kutsetseka.

Mapombi esimbi anoshandiswa gasi, greenhouse uye kudziyisa ariwo mapaipi ane galvanized.Semapombi emvura, mapaipi akabatiswa anoburitsa huturu hwakawanda uye chiyero mumapombi.Mvura yero haingosvibisi zvinhu zvehutsanana chete, asiwo yakasanganiswa nebhakitiriya inobereka pamadziro emukati asina kupfava.Corrosion inokonzeresa kuti zviri mukati mesimbi inorema mumvura zvinyanye kukwira, izvo zvinokanganisa hutano hwevanhu zvakanyanya.Mumakore ekuma1960 nema1970, nyika dzakasimukira pasi rose dzakatanga kugadzira pombi itsva, uye mapaipi emarara akarambidzwa imwe pashure peimwe.Bazi rezvekuvaka reChina nemamwe mapazi nemakomisheni mana vakabudawo pachena kuti pombi dzemarata dzakarambidzwa kubva muna 2000. Mapombi ane malata haawanzo shandiswa pakugadzira pombi dzemvura inotonhora munharaunda itsva, uye mapaipi ane marata anoshandiswa papombi dzemvura inopisa mune dzimwe nharaunda.
