Mapaipi esimbi ane galvanized anoshandiswa zvakanyanya, kwete chete mukugadzira basa, asiwo mukugadzirwa kwemichina, nezvimwewo, izvo zvinogona kutsanangurwa seyakasiyana-siyana uye mune dzakasiyana siyana minda.Paunenge uchitenga mapaipi esimbi ane galvanized, vatengi vakawanda vanofarira zvikuru kushandiswa kwepombi dzesimbi.Pamusoro pezvo, havazive zvakawanda nezvemhando dzemapombi esimbi.Nhasi tichadzidza zvakawanda pamusoro pavo..
Chii chinoshandiswa nenyere dzesimbi?
1. Kune marudzi maviri emapombi esimbi ane galvanized: hot-dip galvanizing uye electric galvanizing.Kupisa-dip galvanizing kune gobvu remarara, iro rine zvakanakira kupfeka yunifomu, kunamatira kwakasimba, uye hupenyu hurefu hwebasa.Mutengo weelectro-galvanizing wakadzikira, nzvimbo yacho haina kunyatso kutsvedzerera, uye kushorwa kwayo kwakaipisisa kupfuura iyo inopisa-dip galvanized pombi.
2. Kushandiswa kwepombi dzesimbi: mapaipi esimbi anoshandiswa kugasi uye kudziyisa ariwo mapaipi ane galvanized.Mapaipi ane galvanized anoshandiswa sepombi dzemvura.Utachiona hunomera pamadziro ane hutsinye hwemukati uye ngura hunokonzera kuwanda kwesimbi inorema mumvura, izvo zvinoisa pangozi hutano hwevanhu.Mumakore ekuma1960 nema1970, nyika dzakasimukira pasi rose dzakatanga kugadzira pombi itsva uye zvishoma nezvishoma dzakarambidza mapaipi emarara.Mapazi nemakomisheni mana anosanganisira bazi rezvekuvaka reChina aburitsawo gwaro rinoti pombi dzemarata dzicharambidzwa kubva muna 2000, uye mapaipi akawanda emvura aimboshandiswa kare achiri kuonekwa nhasi.Parizvino, mapaipi ane marita haawanzo shandiswa mupombi dzemvura inotonhora munharaunda dzichangobva kuvakwa, uye mapaipi ane marita anoshandiswa mupombi dzemvura inopisa mune dzimwe nharaunda.
3. Galvanized ine simba rekudzivirira rakasimba uye rakasimba rinopesana nekuora.Chimiro chose chinoumbwa ne zinc, ichiita dense quaternary crystal, iyo inoumba chipingamupinyi paplate resimbi, nokudaro zvinobudirira kudzivirira kupinda kwezvinhu zvinopisa.Corrosion resistance inobva kusimba rakasimba rekudzivirira rezinc.Kana zinc ichishandiswa pakudzivirira kwechibairo pamicheto yakachekwa, zvikweshwa uye zvikweshwa pajira, zinc inoumba insoluble oxide layer kuti iite dziviriro.
Ndedzipi mhando dzepombi dzesimbi dzakabatiswa?
1. Kupisa-dip galvanized square chubhu: Ichubhu inokwana sikweya inogadzirwa nemarata esimbi kana kuti mitsetse yesimbi mushure mekupwanya nekuumbwa.Pahwaro hweiyi sikweya chubhu, sikweya chubhu inoiswa mudziva rinopisa-dip galvanizing kuti riite zvakatevedzana zvemakemikari reaction.Gare gare yakagadzira square chubhu.Iyo yekugadzira nzira yekupisa-dip galvanized square chubhu iri nyore, uye kugona kwekugadzira kwakakwira zvakanyanya, uye kune akawanda marudzi uye zvakatemwa.Rudzi urwu rweskweya chubhu inoda midziyo mishoma uye capital, uye inokodzera kugadzirwa kwediki galvanized square chubhu vanogadzira.Asi maererano nekusimba, kusimba kwerudzi urwu rwepombi yesimbi kwakadzikira zvikuru kupfuura kweseamless square pombi.
2. Iyo inotonhora galvanized square chubhu inoshandisa musimboti wekutonhora wekunamisa pane sikweya chubhu inoshandiswa kugadzira sikweya chubhu anti-corrosion.Yakasiyana nekupisa-dip galvanizing, kutonhora-dhip galvanizing kunonyanya kushandisa electrochemical nheyo kudzivirira ngura.Naizvozvo, zvinodikanwa kuve nechokwadi chekubatana kwakaringana pakati pezinc poda nesimbi kugadzira electrode inogona mutsauko.Nokudaro, kurapwa kwepamusoro kwesimbi kunokosha zvikuru.
Mhando uye zvirevo zvepombi dzesimbi dzakasarudzwa munzvimbo dzakasiyana dzakasiyana.Paunenge uchitenga, unogona kusarudza zvinoenderana nezvaunoda.Chenjerera pakusarudza mapaipi esimbi ane zita.Izvo zviri pamusoro apa ndiyo sumo yakakodzera pamusoro pekushandiswa kwepombi dzesimbi dzakagadziriswa uye ndedzipi mhando dzepombi dzesimbi.
