The difference between galvanized bridge and hot-dip galvanized bridge

Galvanized Bridge frame:

Zambuko rakabatidzwa, rinozivikanwawo sezambuko remagetsi; Kazhinji zvinonzwisiswa sezambuko rine galvanized iro rinopisa-dip galvanized zambuko, kutaura zvazviri, hazvina kunaka, sepombi yakabatiswa, zambuko rakabatiswa rakakamurwa kuita mhando mbiri, dzinoti, inotonhora yemagetsi (yemagetsi galvanized) uye inopisa-dip galvanized (inopisa-dip galvanized );

Simbi nesimbi zvinoita ngura zviri nyore mumhepo, mumvura kana muvhu, kana kutoparara zvachose. Kurasikirwa kwesimbi kwegore negore kunokonzerwa nekuora kunokwana 1/10 yesimbi yose yakabuda. Kune rumwe rutivi, kuitira kugadzira zvigadzirwa zvesimbi uye zvikamu zvine basa rinokosha pamusoro pepamusoro, uye kupa chimiro chayo chekushongedza panguva imwe chete, saka inowanzobatwa nenzira yemagetsi emagetsi.

1.Chisungo:

Nekuti zinc haisi nyore kuchinja mumhepo yakaoma, uye mumhepo ine hunyoro, iyo nzvimbo inogona kuumba yakanyanya kuomarara zinc carbonate firimu, iyi firimu inokwanisa kudzivirira mukati kubva mukuora. Uye kana iyo yekuputira yakakuvadzwa nekuda kwechimwe chikonzero uye chigadziko chesimbi hachina kunyanya kukura, zinc uye simbi matrix inoumba microbattery, kuitira kuti matrix esimbi ive cathode uye inodzivirirwa.

2. Maitiro Ekuita:

1) Iyo zinc coating yakakora, iyo crystallization yakanaka, yunifomu uye isina pores, uye kushorwa kwecorrosion kwakanaka;

2) Zinc layer inowanikwa ne electroplating yakachena uye inoodza zvishoma nezvishoma mu acid uye alkali fog, iyo inogona kunyatso chengetedza simbi matrix;

3) Zinc coating yakaumbwa nechromic acid passivation chena, ruvara, girini yemauto, yakanaka, ine imwe yekushongedza;

4) Nekuti iyo zinc coating ine yakanaka ductility, inogona kutonhora kuvharika, kukunguruka, kupeta uye kumwe kuumba pasina kukuvadza kupfekedza.

3. Sarudzo yekushandisa:

Nekuvandudzwa kwesainzi uye tekinoroji, indasitiri ye electroplating inosanganisira yakawanda uye yakawanda minda. Parizvino, kushandiswa kwe galvanizing kwave kuri mukati mekugadzira nekutsvaga madhipatimendi ehupfumi hwenyika. Semuyenzaniso, kugadzira michina, zvemagetsi, midziyo chaiyo, indasitiri yemakemikari, indasitiri yemwenje, zvekufambisa, zvombo, mhepo, simba reatomu, zvichingodaro, zvakakosha zvikuru muhupfumi hwenyika.

Kupisa-dip galvanized zambuko(kupisa-dip zinc zambuko)

1, tsananguro inopisa dip zinc:

Kupisa dip zinc ndiyo imwe yedzakanakisa nzira dzekuputira dzekudzivirira simbi substrate. Iyo iri mumvura ye zinc, mushure mekuoma kwakaoma kwemuviri uye kemikari kuita, kwete chete pane simbi yeplating yakakora yakachena zinc layer, asiwo inoburitsa zinc - iron alloy layer. Iyi nzira yeplating haingove nehunhu hwekupokana kwe galvanizing, asiwo ine zinc-iron alloy layer. Iyo inewo yakasimba corrosion resistance iyo isingagoni kuenzaniswa ne galvanizing. Naizvozvo, iyi nzira yekuisa yakanyatsokodzera marudzi ese easidhi yakasimba, alkali fog uye imwe nharaunda yakasimba yekuora.

2.Chisungo:

Kupisa dip zinc layer inoumbwa mumatanho matatu pasi pemvura yakanyanya tembiricha:

1) Iron base surface inonyungudutswa ne zinc solution kuti iite zinc-iron alloy phase layer;

2) Ioni dzezinc mu alloy layer inowedzera kupararira kune matrix kuti iite zinc-iron miscible layer;

3) Pamusoro peiyo alloy layer inovhara zinc layer.

3. Maitiro ekuita:

(1) Iine gobvu yakakora yakachena zinc layer yakavhara pamusoro pesimbi, inogona kudzivirira iyo simbi matrix uye chero ngura mhinduro yekubata, kudzivirira iyo simbi matrix kubva mukuora. Mumamiriro ekunze, iyo zinc layer inoumba yakanyanya kutetepa uye dense zinc oxide layer pamusoro, yakaoma kunyungudika mumvura, saka inotamba imwe nzvimbo yekudzivirira pane simbi matrix. Kana zinc oxide uye zvimwe zvikamu zviri mumhepo kuti zvigadzire insoluble zinc munyu, kudzivirirwa kwekuora kunonyanya kunaka.

(2) Kune iron - zinc alloy layer, compact, muMarine munyu wekupfapfaidza mamiriro ekunze uye maindasitiri mamiriro ekunze anoita akasiyana ngura kuramba;

(3) Nekuda kwekubatanidzwa kwakasimba, zinc-iron miscible, ine yakasimba kupfeka kuramba;

(4) Nekuti zinc ine yakanaka ductility, alloy layer yayo uye chigadziko chesimbi chakanyatsobatanidzwa, saka zvikamu zvinopisa zvekuputira zvinogona kutonhora kutsika, kutenderedza, kudhirowa, kupeta uye mamwe mafomu pasina kukuvadza coating;

(5) Mushure mekupisa-dip galvanizing yesimbi yezvimiro zvezvikamu, zvakaenzana neanealing imwe chete kurapwa, iyo inogona zvinobudirira kuvandudza michina yesimbi matrix, kubvisa kushushikana panguva yekugadzira uye welding yezvikamu zvesimbi, uye inokodzera kutendeuka. yezvikamu zvesimbi.

(6) Pamusoro pezvishandiso mushure mekupisa dip galvanizing inopenya uye yakanaka.

(7) Yakachena zinc layer ndiyo yakanyanyisa plastiki layer yekupisa dip galvanized layer, zvimiro zvayo zviri padyo ne pure zinc, ductility, saka inochinjika.

4. Sarudzo yekushandisa:

Iko kushandiswa kwekupisa dip galvanizing kunowedzera nekuvandudzwa kweindasitiri nekurima. Naizvozvo, kupisa-dhip kwakakurudzira zvigadzirwa muindasitiri (senge makemikari midziyo, petroleum processing, Marine kuongorora, simbi chimiro, simba kufambisa, shipbuilding, etc.), zvekurima (zvakadai: kudiridza, greenhouse), kuvaka (zvakadai: mvura uye kutapurirana gasi, wire casing, scaffolding, dzimba, Bridges, transportation, etc., zvave kushandiswa zvakanyanya mumakore achangopfuura Hot-dip galvanized products zviri kuwedzera uye zvakanyanya kushandiswa nekuda kwechitarisiko chazvo chakanaka uye kurwisa kunaka kwekuora.

Chechipiri, musiyano uripopfapfaidzo zambukouyezambuko rakabatidzwa

Kupfapfaidza bhiriji uye galvanized bhiriji zvinongosiyana mukuita, iyo yakatarwa, mhando, chimiro uye chimiro chebhiriji zvakafanana.

Musiyano wemaitiro pakati pekupfapfaidza bhiriji uye galvanized bridge:

Kutanga kwazvose,zambuko rakabatidzwauye plastiki yekupfapfaidza zambuko ndeyesimbi tambo zambuko, galvanized bhiriji rakagadzirwa nesimbi ndiro, galvanized plate ndinotenda kuti hapana chikonzero chekutsanangura zvakanyanya, uye bhiriji rekupfapfaidza epurasitiki rinoshandiswa kugadzira dhizaini yekupfapfaidza yemagetsi pamusoro. yebhiriji yakabatiswa, saka inonzi mapurasitiki ekupfapfaidza zambuko, nzwisiso iri nyore ndeyokuti zambuko repurasitiki rekupfapfaidza ndiro vhezheni yekuvandudza yebhiriji rakabatiswa, kupikisa kusimba kwakasimba.
