Anti-corrosion ye galvanized simbi pombi welding: Mushure mekurapa kwepamusoro, inopisa pfapfaidzo zinc. Kana galvanizing isingaite pa-saiti, unogona kutevera on-saiti anti-corrosion nzira: bhurashi epoxy zinc-rich primer, epoxy micaceous iron yepakati pendi, uye polyurethane topcoat. Ukobvu hunoreva zviyero zvakakodzera.

Zvinoumba galvanized simbi pombi muitiro
1. Optimization ye sulfate galvanizing: Kubatsira kwe sulfate galvanizing ndeyokuti kushanda kwemazuva ano kwakakwirira se100% uye chiyero chekuisa chinokurumidza, chisingaenzaniswi nemamwe maitiro ekugadzira. Nemhaka yokuti crystallization yekuputira haina kukwana, kukwanisa kupararira uye kukwanisa kudzika kwakadzika hazvina kunaka, saka inokodzera chete mapombi e electroplating uye waya ane maumbirwo akareruka ejometri. Iyo sulfate electroplating zinc-iron alloy process inogonesa iyo yechinyakare sulfate galvanizing process, ichichengeta chete main salt zinc sulfate, uye kurasa zvimwe zvikamu. Muchigadzirwa chitsva chemaitiro, huwandu hwakakodzera hwesimbi munyu hunowedzerwa kuita zinc-iron alloy coating kubva kune yekutanga simbi yekuputira. Kurongeka patsva kwemaitiro hakungosimudzire zvakanakira maitiro ekutanga epamusoro ikozvino kushanda uye nekukurumidza deposition rate asi zvakare inovandudza zvakanyanya kugona kwekuparadzira uye yakadzika plating kugona. Munguva yakapfuura, zvikamu zvakaoma zvaisagona kuputirwa, asi iye zvino zvose zviri nyore uye zvakaoma zvikamu zvinogona kuputirwa, uye maitiro ekudzivirira ari 3 kusvika ku5 nguva yakakwirira kupfuura yesimbi imwe chete. Kugadzirwa kwemaitiro kwakaratidza kuti kuenderera mberi kwe electroplating yewaya nemapombi kune yakatsetseka uye inopenya yekubatisa tsanga kupfuura yekutanga, uye mwero wekuisa unokurumidza. Ukobvu hwekuputira hunosvika pane zvinodiwa mukati me2 kusvika kumaminitsi matatu.

2. Shanduko ye sulfate zinc plating: Sulfate electroplating ye zinc-iron alloy inongochengeta munyu mukuru zinc sulfate ye sulfate zinc plating, uye zvakasara zvikamu zvakadai sealuminium sulfate uye alum (potassium aluminium sulfate) inogona kuwedzerwa ne sodium hydroxide panguva plating mhinduro kurapwa kugadzira insoluble hydroxide kunaya kwekubvisa; kune organic additives, powdered activated carbon inowedzerwa adsorption uye kubvisa. Muedzo unoratidza kuti aluminium sulfate uye potassium aluminium sulfate yakaoma kubvisa zvachose panguva imwe chete, iyo ine simba pakupenya kwekuputira, asi haisi yakakomba uye inogona kupedzwa nekubviswa. Panguva ino, kupenya kwejasi kunogona kudzorerwa. Mhinduro yacho inogona kuwedzerwa maererano nezviri mukati mezvikamu zvinodiwa nemaitiro matsva mushure mekurapa, uye kutendeuka kunopedzwa.

3. Fast deposition rate uye yakanakisa kudzivirira kushanda: Ikozvino kushanda kwe sulfate electroplating zinc-iron alloy process yakakwira se100%, uye kukurumidza kuisa chiyero hachifananidziki nechero galvanizing process. Iyo yekumhanya yekumhanya yechubhu yakanaka ndeye 8-12m/min, uye avhareji yekuputira ukobvu ndeye 2m/min, izvo zvakaoma kuwana nekuenderera mberi kwe galvanizing. Iyo yekupfeka inopenya, yakatetepa, uye inofadza ziso. Zvinoenderana neiyo yenyika standard GB/T10125 "Artificial Atmosphere Test-Salt Spray Test" nzira, iyo yekupfeka haina kuchinjika uye haina kuchinjika kwemaawa makumi manomwe nemaviri; diki diki chena ngura rinoonekwa pamusoro pekupfeka mushure memaawa makumi mapfumbamwe nematanhatu.

4. Yakasarudzika yakachena kugadzirwa: Iyo galvanized simbi pombi inotora sulfate electroplating zinc-iron alloy process, izvo zvinoreva kuti mitsara yekugadzira mitsara inoputika zvakananga uye mhinduro haina kuitwa kana kufashukira. Imwe neimwe maitiro ekugadzira maitiro ane inotenderera system. Mhinduro dzetangi rega rega, dzinoti acid uye alkali solution, electroplating solution, uye light and passivation solution, zvinongodzokororwa uye kushandiswazve pasina kuvuza kana kubuda kunze kwehurongwa. Mutsara wekugadzira unongova ne5 matangi ekuchenesa, ayo anodzokororwa uye kushandiswazve nguva dzose, kunyanya mukugadzira nzira pasina kugadzirwa kwemvura yetsvina mushure mekufamba.

5. Hunhu hwemagetsi emagetsi emagetsi: Iyo electroplating yemapombi esimbi yakakoshwa yakafanana neiyo electroplating yewaya dzemhangura, ayo ese ari maviri anoenderera e electroplating, asi midziyo yeplating yakasiyana. Tangi yeplating yakagadzirirwa maitiro akatetepa ewaya yesimbi yakareba uye yakafara asi haina kudzika. Panguva ye electroplating, simbi yesimbi inopfuura nepakati pegomba uye inopararira pamusoro pemvura yemvura mumutsara wakatwasuka, ichichengetedza chinhambwe kubva kune mumwe. Zvisinei, mapaipi esimbi ane galvanized akasiyana newaya dzesimbi uye ane maitiro awo akasiyana. Iyo tangi midziyo yakanyanya kuoma. Iyo tangi muviri inoumbwa nepamusoro uye pasi zvikamu. Chikamu chepamusoro ndicho tangi yekuputira, uye chikamu chezasi ndiyo mhinduro yekutenderera yekuchengetedza tangi, ichigadzira trapezoidal tangi muviri wakatetepa kumusoro uye wakafara pazasi. Pane mugero we electroplating yemapombi esimbi ane galvanized mu plating tank. Kune maviri kuburikidza nemakomba ari pazasi petangi akabatana netangi yekuchengetera pazasi, uye anogadzira plating mhinduro kutenderera uye kushandisa zvakare sisitimu nepombi inonyudza. Nokudaro, kurovererwa kwepombi dzesimbi kune simba, kungofanana ne electroplating yewaya dzesimbi. Kusiyana ne electroplating yewaya dzesimbi, iyo yekuisa mhinduro ye electroplated galvanized simbi pombi inewo simba.
