Unodzivirira mapaipi esimbi kubva kungura nekushandisa galvanizing inodziya.Midziyo yesimbi yekuisa galvanizing inopisainofukidza pombi yega yega ne zinc, zvichiita kuti pave nekudzivirira ngura.Mapaipi Mitsetse yemagetsibatsirai kuona kuti madziro acho akasimba uye akaenzana. Tarisa chati iri pazasi. Inoratidza kuti mapaipi emagetsi anogara kwenguva yakareba sei munzvimbo dzakasiyana.
Zvinhu Zvinokosha Zvaunofanira Kuziva
- Kupisa-kunyikainodzivirira mapaipi esimbi kubva kungura nekuisa zinc coating yakakora, iyo inoshanda sechidziviriro kubva kungura.
- Kugadzirira zvakanaka pamusoroZvakakosha. Kuchenesa nekunatsa mapaipi kunoita kuti zinc inamire zvakanaka, zvichidzivirira zvikanganiso pakuputira.
- Mapaipi esimbi akasimba anogara kwenguva refu, anowanzogara kwemakore makumi mana kusvika makumi mashanu, zvichiita kuti ave sarudzo isingadhuri kumaindasitiri akasiyana-siyana.
Matanho Ekugadzira Pipe Yesimbi Inopisa-Dip Galvanizing
Pombi yesimbimichina yekupisa-kunyikaInokubatsira kudzivirira mapaipi esimbi kubva kungura nekukuvadzwa. Unoshandisa michina iyi mumaindasitiri akawanda, akadai sekuvaka, michina, mafekitori emakemikari, uye njanji. Midziyo iyi inobata mapaipi ane dhayamita kubva pa 1/2 kusvika 10 inches uye kureba kubva pamamita 4 kusvika 8. Inogona kuputira mapaipi ne zinc inorema pakati pe 50 ne 400 magiramu pa square mita. Midziyo iyi inogona kugadzira mapaipi esimbi anosvika matani 80,000 gore rega rega.

Kugadzirira uye Kuchenesa Pamusoro
Unotanga nekuchenesa mapaipi esimbi. Danho iri rinobvisa tsvina, mafuta, nezvimwe zvinosvibisa. Kana ukarega kuchenesa, zinc coating haizonamati zvakanaka. Unofanira kubvisa weld slag, burrs, mill scale, varnishes, epoxies, jecha, pendi dzakavakirwa pamafuta, crayon marks, uye gobvu wax kana grease. Unoshandisa degreasing baths nesodium hydroxide kubvisa mafuta nemafuta. Mushure mekubvisa mafuta, unosuka mapaipi nemvura. Unobva washandisa hydrochloric kana sulfuric acid kubvisa ngura ne mill scale. Danho iri rinonzi pickling.
Zano: Gara uchisuka mapaipi mushure mekuchenesa acid kuti ubvise zvisaririra zveacid. Omesa mapaipi zvachose usati waenda kunhanho inotevera.
Kugadzira Mapaipi Esimbi
Tevere, unonyika mapaipi mu flux solution. Fluxing inobvisa chero ma oxide asara uye inodzivirira oxidation itsva usati waisa zinc mumapaipi. Unoshandisa zinc ammonium chloride solution padanho iri. Tembiricha yakanakisa yeku flux iri pakati pe60 ne80 °C. Tembiricha iyi inobatsira flux kuchenesa pamusoro pesimbi zvakanaka. Zvinhu zvikuru zvino fluxing agents i zinc chloride uye ammonium chloride. Makemikari aya anobvisa iron oxide uye anovandudza kufamba kwe zinc. Fluxing inokubatsirawo kushandisa zinc shoma uye inoderedza marara.
- Zinc chloride: 60–80%
- Ammonium chloride: 7–20%
- Zvinhu zvinogadzirisa kuyerera kwemvura: 2–20%
- Mamwe makemikari: nickel, cobalt, manganese, lead, tin, bismuth, antimony
Kunyudzwa muZinc Bath
Wobva wanyika mapaipi mubhavhu rezinc yakanyungudutswa. Midziyo yesimbi inodziya-inodzika galvanizing inochengetedza zinc bath patembiricha yakakodzera, kazhinji iri pakati pe825 ne870 °F (440–460 °C). Unochengeta mapaipi mubhavhu kwemaminitsi mashanu kusvika gumi nemashanu. Panguva ino inoita kuti zinc ibatane nesimbi uye iite coating yakasimba, yakaenzana. Zinc bath inofukidza chikamu chega chega chepaipi, kunyangwe mukati nepakapoteredza welds.
Cherechedza: Kana usingadzore tembiricha kana nguva, unogona kuwana zvikanganiso zvakaita semapundu, maronda, kana kukwesha.
Kutonhodza uye Kuchenesa Kwekupedzisira
Mushure mekubvisa mapaipi mubhavhu rezinc, unoatonhodza mutangi rekudzimisa. Kutonhodza kunomisa kusangana pakati pezinc nemhepo. Wobva wasuka mapaipi nemvura yakachena kubvisa chero makemikari asara. Kana wakashandisa kuchenesa neacid, sukurudza mapaipi kechipiri. Omesa mapaipi nemhepo inopisa kuti uve nechokwadi chekuti hapana hunyoro huripo. Danho iri rinochengetedza pamusoro pakachena uye rinodzivirira ngura chena.
- Shamba nemvura yakachena
- Oma nemhepo inopisa
- Chengeta mapaipi munzvimbo yakaoma
Kuongorora uye Kuedzwa Kwemhando
Unofanira kuongorora mapaipi kuti uve nechokwadi chekuti chifukidziro chacho chakasimba uye chakaenzana. Unoshandisa zviono, kuyera ukobvu, uye bvunzo dzekuti akaenzana. Unotarisawo kana paine kuomarara, ngura, uye kukuvara. Unoyera saizi yepaipi wobva watarisa kana paine mvura inodonha. Unotevera zviyero zvakaita seASTM A500 neEN 10219. Izvi zvinokubatsira kuona kuti mapaipi acho anogara kwenguva refu uye haapindi ngura.
Maitiro Ekuongorora Tsananguro Kuongorora zvinoonekwa Tarisa kana kutsvedzerera, zvikanganiso, uye ngura Ukobvu hwechikamu Shandisa mita kuyera ukobvu hwekufukidza Kufanana Tsvaga kana paine ganda rakachekwa kana kuti risina kuenzana Kuomarara Kuoma kwenzvimbo yekuyedza Kuongorora ngura Tsvaga mavanga kana kukuvara Hunhu hwekunamira Tarisa kana paine mitswe kana tsvina Kuumbwa kwemakemikari Edza kuti uone kana zinc nesimbi zviri mukati mazvo here.

Dziviriro Yepamusoro Yengura Nengura
Unowana dziviriro yakasimba kubva kungura kana uchishandisamichina yesimbi yekuisa galvanizing inopisaZinc coating inoita chipingamupinyi chakakora chinochengetedza mvura, mhepo, uye makemikari kure nesimbi. Chipingamupinyi ichi chinoshanda zviri nani pane pendi kana machira matete. Zinc inodzivirirawo simbi kana chiputiro chikakwenywa. Zinc inotanga yaora, ichichengetedza simbi iri pasi.
- Rutivi rwakakora rwezinc runodzivirira mamiriro ekunze akaoma uye makemikari.
- Unoona nzira iyi ichishandiswa pamabhiriji, masimbi, nemapombi ekunze nekuti inogara kwenguva yakareba.
- Zinc coating inoshandisa zvese kudzivirira kukuvara uye kudzivirira kukuvara, saka mapaipi ako anoramba akachengeteka kunyangwe pamusoro pawo pakakuvara.
Ongororo dzesainzi dzinoratidza kuti zinc inoumba makemikari akakosha, akadai seZnO neZn5Cl2(OH)8, ayo anononoka ngura uye anochengetedza mapaipi akasimba munzvimbo dzakaoma.
Maitiro Tsananguro Dziviriro yeZvipingamupinyi Zinc layer inovhara mvura nemhepo kuti zvisasvike pasimbi. Dziviriro Yechibayiro Zinc inoora simbi isati yagadzirwa, ichiidzivirira kunyangwe ikakwenywa. Mamiriro ekunze echisikigo Nekufamba kwenguva, zinc inoumba mamwe mativi anowedzera dziviriro. Kugara Kwakasimba uye Kugara Kwenguva Refu
Unogona kutarisira kuti mapaipi esimbi agare kwemakumi emakore. Kana zinc coating yacho yakakora, mapaipi ako anogara kwenguva refu. Semuenzaniso:
Rudzi rwekuputira Nguva Inotarisirwa Yehupenyu Munzvimbo Dzine Mwero G30 Makore mashanu kusvika gumi G90 Makore makumi maviri kana kupfuura Mapombi mazhinji esimbi anogadzikwa nemagetsi anogara kwemakore angangoita 40 kusvika 50. Munzvimbo dzakaoma, anogona kugara kwenguva yakareba. Kana ukashandisa michina yesimbi inogadzikwa nemagetsi inodziya, unobatsira mapaipi ako kudzivirira ngura nekukuvadzwa kwemakore mazhinji.
- Mapaipi ari munzvimbo dzisina hunyoro hushoma anogona kugara kwemakore anosvika makumi manomwe.
- Munzvimbo dzakanyorova kana dzine munyu, nguva yekurarama inogona kunge iri pfupi, asi yakareba kupfuura simbi isina kuputirwa.
Kushanda Kwemari Yakawanda Uye Kugadzirisa Kwakaderera
Unochengetedza mari nekufamba kwenguva uchishandisa mapaipi emarasha. Mutengo wekutanga wakakwira zvishoma pane pendi, asi unoshandisa mari shoma pakugadzirisa nekugadzirisa. Heino kuenzanisa kupfupi:

Kuvhara kwawo kwakasimba kunoreva kuti haufanirwe kunetseka nezvengura kana kubuda kwemvura kakawanda. Izvi zvinoita kuti ave sarudzo yakanaka kumapurojekiti makuru nenzvimbo dzaunoda kuti mapaipi agare kwenguva refu.
Midziyo yemagetsi inodziya inokubatsira kuchengetedza mapaipi esimbi kwemakore mazhinji. Unowana kushanda kwakavimbika munzvimbo dzakasiyana.
- Kugara kwenguva refu kunoenderana nemamiriro ekunze.
- Nyanzvi dzinotidanho rega rega rekuita rinokanganisakunaka uye simba rekuputira.
