Anticorrosion Of Ductile Iron Pipe Zinc Layer

Ka ts'ebeliso e potlakileng le e pharalletseng ea lipeipi tsa tšepe tsa ductile indastering ea metsi le khase, tlhahiso ea China ea selemo le selemo e eketsehile ho tloha ho lithane tse 100,000 ka 1990 ho isa ho 900,000 tonnes ka 2001, e ikarabellang ho feta 50% ea kakaretso ea liphaephe tsa tšepe tsa cast. Anti-corrosion ea ductile iron pipe e amana ka kotloloho le ts'ebeliso ea nako e telele le polokeho ea phaephe, ka hona ke sesupo sa bohlokoa sa ho metha theknoloji le maemo a ts'ebetso ea marang-rang a lipeipi. Ho latela liphetho tsa phuputso ea litoropo tse 10 tse tloaelehileng, sekhahla sa ho lutla sa marang-rang sa phepelo ea metsi ea toropo ea China se fihlile ho 12 ~ 13%, e neng e feta hole boemo ba naha ba hore sekhahla sa ho dutla ha litoropo se lokela ho laoloa ka tlase ho 6%. Ka hona, anti-corrosion ea lipeipi esale e le taba e chesang ho rona. Sehlooho.

Hajoale, liphaephe tsa tšepe tse nang le nodular li sebelisa lera la samente joalo ka foromo ea ka hare e khahlanong le ts'enyeho, le zinki hammoho le asphalt joalo ka mofuta oa kantle oa ho bola, 'me li entsoe molemong oa tlhahiso, ntle le tlhoko ea kalafo ea anti-corrosion kamora kaho le ho kenya. Sena se fetohile tloaelo e tloaelehileng bakeng sa baetsi ba lipeipi tsa tšepe tsa ductile lapeng le kantle ho naha, mme phello e khahlanong le ts'enyeho le eona e hlakile haholo.　　

Ho Article 4.4.2.2 ea "Lisebelisoa tsa lipeipi" le ho Article 4.4 ea standard standard ea ISO 8179-1: 1995 (E) "Nodular cast iron pipe-Outer barging-Part I", ho hlakile hore bongata ba zinki lera ha le na ho ba tlase ho 130g / m2, letsoalo le tlase la lehae le ke ke la ba tlase ho 110g / m2. Maemong a naha ea China a GB / T17456-1998, standard standard ea machabeng ISO 8179-1: 1995 le eona e amohetsoe.

Ho na le liphuputso tse fokolang haholo mabapi le ho thibela ts'oaetso ha liaparo tsa zinki Chaena, empa kantle ho naha, haholo-holo Borokho ba Saint-Gobain Musong, patlisiso e khahlanong le ts'enyeho ea liaparo tsa zinc e na le nalane ea lilemo tse fetang 60. Maemong a kahare a Borokho ba Saint-Gobain Musong, zinc + asphalt foromo e khahlano le ts'enyeho e ikemiselitsoe e le lera la mantlha la anti-corrosion la lipeipi tsa tšepe tsa ductile, mme e loketse mefuta e mengata ea mobu. Ka nako e ts'oanang, ena hape ke phala ea ductile ea tšepe ea linaha tse tsoetseng pele joalo ka Europe. Mokhoa o tloaelehileng o kantle ho ts'enyeho oa kantle.

Ts'enyeho Ea Mobu Ho Ductile Tšepe Pipe

1. Ts'oaetso ea motlakase

Khokahano lipakeng tsa tšepe le tharollo ea electrolyte e tla hlahisa phello ea motlakase, 'me ho tla ba le phapang e ka bang teng lipakeng tsa bokaholimo le tharollo, ke hore, bokhoni ba elektrode. Bokaholimo ba tšepe bo kanna ba ba le mekhahlelo e fapaneng ka lebaka la meeli e fapaneng ea lijo-thollo, liphoso tsa kristale, inclusions, khatello ea maikutlo le tšenyo ea bokaholimo. Ts'ebetso ena ea motlakase ea motlakase e etsa hore menyetla ea li-electrode ea likarolo tse fapaneng tse nyane tsa tšepe e fapane, e leng sele ea ts'enyeho. Li-elektronike tse lahlehileng karolong e nang le bokhoni bo tlase li fetoha li-ion tsa tšepe ebe li kenya tharollo, e bitsoang anode; lielektrone phalla ho karolo ea phahameng-nang le monyetla 'me e be cathode. Ka lebaka la karabelo ena ea galvanic, mafome a mangata a thehoa holim'a tšepe.

Phallo ea phallo ea oksijene bakeng sa phala ea tšepe ea ductile: Ha phala ea tšepe ea ductile e patiloe mobung o metsi, mokokotlo o kaholimo o batla o hlephile ebile o le haufi le mobu, athe tlase ke mobu oa mantlha, mobu o motenya ebile o hole ho tloha fatshe. Ha oksijene e kenella holimo ho tloha holimo, e tla baka phapang mokokotlong oa oksijene kaholimo le ka tlasa phala, mme phala ka boeona ke eleketrode le terata e hokahanyang eleketrode; metsi ke electrolyte, ka hona ho thehoa "betri ea phapang ea khatello ea oksijene". Iron e lahleheloa ke lielektrone ebe e kenella filiming ea metsi, 'me oksijene e fumana lielektrone ho ba li-ion tsa hydroxide.

2. Ts'oaetso ea likokoana-hloko

Ts'oaetso ea likokoana-hloko hape ke mofuta oa ts'enyeho ea motlakase. Phapang ke hore seaplane se fetola likarolo tse ling tsa 'mele le lik'hemik'hale tsa sehokelo sa thepa ka ho kopana le sona ka lebaka la ho ikatisa le metabolism ea likokoana-hloko tse senyang. Ka tloaelo, e ka aroloa ka ts'enyeho ea anaerobic le ts'enyeho ea aerobic.

Libaktheria tse fokotsang sulphate SBR ke sesosa se batlisisitsoeng ka ho fetesisa sa anaerobic se bakiloeng ke ts'enyeho har'a likokoana-hloko. Von Wogozen Kuhr et al. Ba ile ba etsa tlhahiso ea hore ho be le khopolo ea khale ea ho fokotsa matla ka 1974. Ba ne ba lumela hore ts'enyeho ea lipeipi tsa tšepe e patiloeng e ne e bakoa ke ts'ebetso ea SBR ea ho theola bokaholimo ba tšepe ka hydrogenase. Tsela e akaretsang ea karabelo ke e latelang:

4Fe + SO42- + 4H2O 3Fe (OH) 2 + FeS + 2OH-

Libaktheria tsa Aerobic ke libaktheria tse nang le tšepe ea tšepe, libaktheria tsa sulfide le libaktheria tsa tšepe. Asiti ea sulfuric e hlahisoang ke ketso ea libaktheria tsa sebabole e ka baka ts'enyeho ea aerobic. Libaktheria tsena li ka phela ha mohopolo oa asiti ea sulfuric o fihla ho 10-12%, mme e ka baka ts'enyeho e matla ho lahla tšepe. Lebaka le leng ke hore libaktheria lia ikatisa holim'a tšepe tlasa maemo a aerobic ho etsa biofilm e sa tloaelehang. Mesebetsi ea likokoana-hloko e baka liphetoho tikolohong ka har'a biofilm, joalo ka moea oa oksijene, boleng ba PH, pH, jj.
