Maindasitiri mazhinji anoshandisa galvanized steel nekuti anogara kwenguva refu. Ivo vanotevera zviyero seASTM A123/A123M uye ASTM A653.
Key Takeaways
Pepa resimbi rine gobvu zinc layer. Iyi layer inomisa mvura nemhepo kubata simbi. Izvi zvinoita kuti simbi irege kuita ngura.
Zinc inozvipira kuchengetedza simbi. Inotanga kuita ngura kuitira kuti simbi igare yakachengeteka kubva pakukuvadzwa.
Kana iyo zinc layer ikakweshwa, inogona kuzvigadzirisa. Inoramba ichidzivirira simbi pasi payo.
Ukobvu hwekuputira zinc hune basa nekuti simbi inogara kwenguva yakareba sei. Zinc yakakora inoreva kudzivirira kurinani kwesimbi.
Kuchenesa uye kutarisa galvanized simbi kunobatsira kuti irambe yakasimba. Nekutarisira, inogona kugara makore anopfuura makumi mashanu.
Zinc Coating Dziviriro
Barrier Effect
Pepa resimbi rine simbi ine nhovo yakaoma pairi. Iyo zinc coating inoshanda semadziro pakati pesimbi nemhepo. Mudhuri uyu unochengeta mvura nemhepo kure nesimbi. Kana mvura nemhepo zvisingagoni kubata simbi, ngura haizoitiki.
Zinc inomira pakati pemvura, mhepo, uye simbi kuidzivirira.
Zinc inoumba nhovo yesimbi, inomisa mhepo, mvura, uye zvimwe zvinhu kuti zvisasvike pairi.
Shandong Sino Steel Co., Ltd inoshandisa inopisa-yakanyikwa galvanization kugadzira zinc layer yakakora. Iyi layer inovhara simbi yese. Inobatsira simbi kurwisa ngura uye kugara kwenguva refu munzvimbo dzakaoma.
Masayendisiti akaongorora kuti zinc coatings inochengetedza simbi. Tafura iri pazasi inoratidza mabatiro akasiyana-siyana anoshanda:

Inoramba ichidonha mu impedance |
Kwete kupikisa kwakanyanya kune blistering uye isina simba chipingamupinyi. |
Iyo yakakura impedance kukosha inoreva kudzivirira kwakasimba. Iwe unogona kuona kuti yakanaka zinc layer inochengeta simbi yakachengeteka kwenguva yakareba.
Chibayiro Chiito
Zinc inoita zvinopfuura kungovhara mvura nemhepo. Inodzivirirawo simbi nekupa pachayo kutanga. Kana simbi mbiri dzichibata, senge zingi nesimbi, imwe inozoita ngura pamberi peimwe. Zinc haina kunaka kupfuura simbi, saka inotanga kuita ngura. Izvi zvinonzi galvanic corrosion.
Galvanic corrosion inoitika kana magetsi achifamba pakati pesimbi mbiri dzakasiyana. Simbi inenge yanyanya anodic inoita ngura nekukurumidza, asi imwe simbi inoramba yakachengeteka. Zinc yakanyanya anodic kupfuura simbi, saka inotanga kuita ngura kana yabata chinhu chakaita semvura yegungwa, ichichengetedza simbi kubva ku ngura.
Iwe unogona kuona izvi mune yavo yakajairwa yekudzikisa mikana:
Metal |

Zinc ine mukana wakaderera wekudzikisa pane iron.
Izvi zvinoreva kuti zinc inoita ngura simbi isati yaita.
Kana zinc ikaita ngura, inoita kuti iron isaita ngura.
Iyo zinc layer parata yakabatiswa simbi inozvipa kuti ichengetedze simbi. Ichi ndicho chikonzero vanhu vanoshandisa simbi kunze uye kuvaka zvinhu.
Kuzviporesa
Dzimwe nguva, zinc layer inokweshwa kana kuchekwa. Unogona kufunga kuti ngura yaizotanga pakarepo. Asi galvanized simbi inogona kuzvirapa pachayo. Kana iyo zinc layer yakuvadzwa, zinc ichiri kuchengetedza simbi iri pasi.
Tsanangudzo Yeuchapupu |
Zvawanikwa Zvikuru |
Cathodic kudzivirira zinc |
Zinc inoshanda seanode uye inozvipa kuti idzivirire simbi kana jasi rakuvadzwa. |
Maximum kudzivirira kureba |
Zinc inogona kudzivirira simbi kusvika zvishoma kudarika 1/4' (7 mm) kure, asi izvi zvinodonha sezvo mukweshwa uchikura. |
Pesvedzero yebasa repamusoro |
Kana zinc yakanyanya kushanda, inodzivirira kure. Kana zinc isingaiti, haidziviriri zvakanyanya. |
Mune inopisa-dip galvanized simbi, zingi nesimbi zvinobatana zvakanaka.
Kana iyo zinc layer yakakuvadzwa uye pane mvura, galvanic cell inoumba. Zinc inova anode uye inodzivirira simbi.
Pakutanga, ngura shoma inogona kuoneka pasimbi, asi munguva pfupi, zinc inogadzira jira idzva rinodzivirira simbi. Uku kunonzi 'kuzviporesa'.
Kuzvirapa uku kunoita kuti simbi yerata irambe yakasimba uye yakachengeteka kubva ku ngura, kunyangwe ikakwarwa. Iwe unogona kuvimba nesimbi yakagadziriswa kuzvidzivirira uye kugara kwenguva yakareba munzvimbo dzakawanda.
Zvinhu Zvinokanganisa Corrosion Resistance
Environment
Zvakakosha kufunga nezve kwaunoshandisa galvanized simbi. Nzvimbo yaunosarudza inogona kuita kuti zinc coating igare kwenguva refu kana kupera nekukurumidza. Dzimwe nzvimbo dzine mvura yakawanda, munyu, kana mhepo yakasviba. Zvinhu izvi zvinogona kuita kuti zinc layer iputse nekukurumidza.
Heino tafura inoratidza mabatiro anoita zvinhu zvakasiyana mumhoteredzo zvinokanganisa simbi yakakoshwa:
Environmental Factor |
Tsanangudzo |
Salt Exposure |
Munyu pasimbi nemvura unoita musanganiswa unopedza zinc yekuputira nekukurumidza. |
Industrial and Atmospheric Poltants |
Mhepo yakasviba ine magasi nemvura inogadzira maasidhi anokuvadza zinc layer. |
Humidity uye Hunyoro |
Mhepo yakanyorova inochengeta mvura pasimbi, iyo inobatsira zvinhu zvinokonzeresa ngura uye inoita kuti zinc layer ikurumidze kupera. |
Nzvimbo dzekupfapfaidza munyu |
Zvivakwa zviri pedyo negungwa kana migwagwa ine munyu zvinogona kuita ngura nekukurumidza. |
Industrial exhaust magasi |
Simbi iri pedyo nemafekitari inorohwa nemagasi akaipa anokurumidza kuita ngura. |
Acid kunaya kuratidzwa |
Mvura zhinji ine acid inogona kusuka zinc layer pasimbi. |
Kana iwe ukashandisa galvanized simbi pepa pedyo negungwa, munyu nemhepo zvinogona kupera kuvhara nekukasira. Semuenzaniso, simbi inopisa-dip inoshanda zvakanaka pedyo negungwa, asi kuti inotora nguva yakareba sei zvinoenderana nenzvimbo. Kana ukaisa chivakwa chisingasviki kiromita imwe kubva mugungwa, chinogona kutanga kuita ngura mumakore mashanu kusvika manomwe kana chikarohwa nemafuta emunyanza. Kana ukaiisa panzvimbo ine butiro, inogona kugara makore gumi nemashanu kusvika makumi maviri nemashanu. Mhepo, tembiricha, uye kuti uri pedyo sei negungwa zvese zvine basa kuti rinorwisa sei ngura.
Coating Ukobvu
Kukora kwakaita zinc coating kunoita mutsauko mukuru pakuti simbi yako yegalvanized inogara kwenguva yakareba sei. Iyo yakakora coating inopa dziviriro yakawanda uye inobatsira kuti igare kwenguva refu. Iwe unogona kutarisa kukora kwejasi nekutarisa zviyero zvakaita seASTM A653 kana EN 10346.
Heino tafura inoratidza kuti ukobvu hwekuputira hunochinja sei kuti simbi inogara kwenguva yakareba sei:

Iwe unofanirwawo kutarisa geji uye giredhi resimbi. Magiredhi akaita seSPCC neSGCC anotevera mitemo yakasimba. Simbi yakakora uye machira anorema anobatsira simbi kurwisa ngura zvirinani, kunyanya munzvimbo dzakaoma.
Maintenance
Iwe unogona kubatsira simbi yako yakabatiswa kugara kwenguva refu kana ukaichengeta. Kuchenesa uye kutarisa simbi yako inochengetedza zinc coating yakasimba. Kana ukageza tsvina nemunyu, unovamisa kuti vasakuvadza zinc. Kutarisa simbi yako kunokubatsira kuti uwane zvikwambo kana kukuvadzwa kare, saka unogona kuzvigadzirisa ngura isati yatanga.
Zano: Kana ukachenesa uye uchitarisa simbi yako yemarara kazhinji, inogona kugara makore anopfuura makumi mashanu.
Heano mamwe matanho ari nyore aunogona kutevera:
Kuchenesa Nguva Dzose: Geza tsvina, munyu, uye zvimwe zvinhu zvinonamira pasimbi.
Visual Inspections: Tarisa kune chena ngura, mavanga, kana makwapa uko iyo yekupfeka isipo.
Kugadzirisa Nenguva: Gadzirisa chero kukuvara nekukurumidza kumisa ngura kuti isapararire.
Kana ukasachengeta simbi yako, unogona kuona matambudziko akaita seaya:
Ngura pasi pesimbi kana mvura ikabatwa.
Ngura inobva mumvura ine munyu pedyo negungwa.
Ngura pamacheto akachekwa kana ukasaasunga.
Ngura inotanga kutanga panobatwa simbi dzakasiyana.
Iwe unogona kumisa matambudziko aya nekutora giredhi rakakodzera, uchitevera mitemo, uye nekuchengeta nekutarisira. Nenzira iyi, simbi yako yemarara inoramba yakasimba, yakachengeteka, uye inoramba ichirwisa ngura kwemakore mazhinji.
Galvanized Steel Sheet Durability
Hupenyu hurefu
Galvanized simbi sheet inogona kugara kwenguva yakareba. Kuti inotora nguva yakareba sei zvinoenderana nekuti unoishandisa kupi. Mumaruwa, inogona kugara kusvika kumakore zana. Mumaguta, haigari kwenguva refu nemhaka yetsvina yakawanda. Kana ukaishandisa pedyo negungwa, mhepo ine munyu inoita kuti isanyanya kupera. Asi ichiri kuchengetedza simbi kwemakore akawanda.
