Pombi yakabatiswa, iyo inonziwo galvanized steel pipe, yakakamurwa kuva marudzi maviri: inopisa-dip galvanizing uye electro-galvanizing. Kupisa-dip galvanizing ine zinc layer yakakora uye ine zvakanakira zvekupfeka yunifomu, kunamatira kwakasimba, uye hupenyu hurefu hwesevhisi. Mutengo wepombi dzeelectro-galvanized wakaderera, kumusoro hakuna kunyatso kutsvedzerera, uye kushora kwayo kwakaipisisa kupfuura iyo inopisa-dip galvanized pombi. Kuti uvandudze kushorwa kwepombi dzesimbi, mapaipi ese esimbi anoiswa galvanized. Mapaipi esimbi ane galvanized akakamurwa kuva marudzi maviri: hot-dip galvanizing uye electro-galvanizing. Kupisa-dip galvanizing kune gobvu zinc layer. Oxygen-blown welded pipe: inoshandiswa sepombi yekugadzira simbi inopeperetswa neokisijeni. Kazhinji, madiki-diameter welded simbi mapaipi anoshandiswa. Kuti udzivise ngura, zvimwe zvinoda kunyatsogadziriswa aluminized.
(1)Kugadzirwa kwakachena kwakasiyana
Iyo galvanized pombi inotora iyo sulfate electroplating process ye zinc-iron alloy, zvinoreva kuti kune yakananga perforations pakati pemitsetse yekugadzira madhiri uye madhiri pasina chero kutakura-kunze kana kufashukira kwemhinduro. Imwe neimwe nzira yekugadzirwa kwayo inoumbwa neyekutenderera system. Mhinduro mutangi rega rega, iyo acid uye alkali solution, electroplating solution, light extraction uye passivation solution, zvichingodaro, zvinongodzokororwa chete uye hazvibviswe kana kuburitswa kunze kwehurongwa. Mutsara wekugadzira unongova ne5 matangi ekuchenesa, anoshandisa kutenderera. Shandisa zvakare uye buritsa nguva nenguva, kunyanya mumagadzirirwo ekugadzira ayo asingaburitse mvura yetsvina pasina kuchenesa mushure mekupfuura.
(2) Hunhu hwe electroplating midziyo
Iyo electroplating yemapombi ane galvanized uye electroplating yemhangura waya dzakafanana neinoenderera mberi electroplating, asi plating midziyo yakasiyana. Tangi yeplating yakagadzirwa nekatete tambo chimiro chewaya yesimbi. Iyo tangi muviri wakareba, wakafara asi usina kudzika. Panguva ye electroplating, waya dzesimbi dzinopfuura nemumakomba uye dzinopararira pamusoro pemvura mumutsara wakatwasuka, dzichichengeta chinhambwe pakati pavo. Nekudaro, pombi yakabatiswa yakasiyana newaya yesimbi nekuti ine yayo yakasarudzika maficha uye tangi midziyo yakaoma. Iyo tangi muviri inoumbwa nepamusoro uye pasi zvikamu. Chikamu chepamusoro ndicho tangi yekuputira uye chikamu chezasi ndicho chigadziriso chekuchengetedza tangi, kugadzira trapezoid-senge tangi muviri wakatetepa kumusoro uye wakafara pazasi. Pane chiteshi chemagetsi pombi electroplating kushanda muplating tank. Kune maviri kuburikidza nemakomba ari pazasi pe tangi anotaurirana neakadzika tangi yekuchengetera, uye anogadzira plating mhinduro yekudzokorodza system nepombi inonyudza. Naizvozvo, mapaipi emagetsi akafanana nesimbi wire electroplating, uye zvikamu zvakapetwa zvine simba. Nekudaro, kusiyana nesimbi waya plating, mhinduro yeplating yemapombi ane galvanized ine simba zvakare.
(3) Optimization ye sulfate galvanizing
Zvakanakira zve sulfate galvanizing ndezvekuti kushanda kwazvino kwakakwira se100% uye deposition rate inokurumidza, iyo isingaenzaniswi nemamwe maitiro ekugadzira. Nekuda kwekuti crystallization yejasi haina kunyatsokwana, kugona kuparadzira uye kugona kwakadzika plating hakuna kunaka, saka inokodzera kungoisa pombi nemawaya ane maumbirwo akareruka ejometri. Iyo sulfate electroplating zinc-iron alloy process inogonesa iyo yechinyakare sulfate galvanizing process. Chete huru yemunyu zinc sulfate inochengetwa, uye zvikamu zvakasara zvinoraswa. Huwandu hwakakodzera hwesimbi munyu hunowedzerwa kune itsva maitiro formula kuumba zinc-iron alloy coating kubva kune yekutanga simbi yekuputira. Kurongeka patsva kweiyo maitiro hakungounze kumberi kwakanakira yakakwira ikozvino kushanda uye nekukurumidza deposition mwero weiyo yekutanga maitiro, 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 ariwo 3 kusvika ku5 nguva dzakakwirira kudarika simbi imwe chete. Tsika yekugadzira yakaratidza kuti kana ichishandiswa kuenderera mberi electroplating yewaya nemapombi, zviyo zvekuputira zvinopenya uye zvinopenya kupfuura zvepakutanga, uye mwero wekuisa unokurumidza. Ukobvu hwekuputira hunosvika pane zvinodiwa mukati me2 kusvika kumaminitsi matatu.
(4) Shanduko ye sulfate zinc plating
Sulfate electroplating ye zinc-iron alloy inongochengeta zinc sulfate, munyu mukuru we sulfate zinc plating. Zvikamu zvasara zvakadai sealuminium sulfate, alum (potassium aluminum sulfate), nezvimwewo zvinogona kuwedzerwa mubhati yekuputira panguva yekurapa kuti ibudise mvura isingagadzirike hydroxide. Bvisa; kune organic additives, wedzera powdered activated kabhoni kuti uzvibvise ne adsorption.
Miedzo yevagadziri vepombi yemagetsi yakaratidza kuti aluminium sulfate uye potassium aluminium sulfate yakaoma kubvisa zvachose panguva imwe chete uye ine chekuita nekupenya kwejasi, asi haina kukomba uye inogona kutorwa kuti ishandiswe. Panguva ino, kupenya kwekuputira kunogona kudzorerwa kuburikidza nekurapa nemhinduro. Wedzera izvo zvinodikanwa zvemukati zvinoenderana nehurongwa hutsva hwekupedzisa shanduko.
Kana iwe uchida kuziva zvakawanda nezve galvanized simbi pombi, ndapota inzwa wakasununguka kutibata nesu.
