Pfungwa ye corten simbi

Corten steel imhando yesimbi inogona kushandiswa mumhepo pasina kushandisa chero pende kana zvimwe zvinodzivirira. Simbi ine kupikisa kwakasimba kukukurwa kwemuchadenga, kusimba kwakanaka, kugoneka kwakanaka uye kuchinjika kwakasimba. Pasi pemamiriro echisikigo, pasi pemamiriro ekunze, mvura inonaya, mvura yechando, kutonhora, inogona kuramba ichichengetedza maitiro ayo emagetsi uye kuchengetedza chivako chakasimba kwenguva yakareba.
Parizvino, simbi dzakajairwa kumba nekune dzimwe nyika dzinosanganisira: galvanized corten steel, hot-dip galvanized corten steel, chromium-isina passivated corten simbi uye yakapfapfaidza corten simbi. Pakati pavo, matatu ekutanga ndeaya akajairwa corten simbi mahwendefa, nepo yakapfapfaidzwa corten simbi ndeyeyakakosha corten simbi mahwendefa uye inoda kugadziridzwa kwakakosha.

Kuvandudza corten steel

Corten simbi yakaonekwa mu70s yezana ramakore rechi20, iyo inonyanya kushandiswa kumadziro ekunze, matenga uye zvimwe zvinoshongedza zvezvivakwa. Munguva yekugadzirwa kwe corten simbi, firimu yakakosha yekuora ichagadzirwa pamusoro payo, iyo ine imwe dhigirii yekupikisa oxidation uye kusagadzikana kwemamiriro ekunze, uye gloss yayo yakanaka kwazvo, iyo inowedzera aesthetics yechivako.
Britain, United States, Soviet Union yakaidzidza mukuvamba kwamakumi matanhatu ezana ramakore rechi20. Mukupera kwe70s yezana ramakore rapfuura, United States yakagadzira simbi inodzivirira mamiriro ekunze. United States neSoviet Union dzakatevedzana dzakagadzira austenitic stainless simbi dzakadai seyepamusoro-simba, high-toughness corten simbi, senge corrosion-resistant acid-resistant steel, mukupera kwema80s nekutanga 90s. High nickel-chromium corten simbi rudzi rutsva rwezvinhu zvakashandiswa zvakanyanya muma70s, saka zvakakwezva kutarisa kumba nekune dzimwe nyika. Mumakore achangopfuura, China yakaitawo kufambira mberi kukuru mundima iyi. Mutsara wemhando dzakasiyana-siyana uye mamakisi esimbi zvakagadzirwa.

Chii chatinofanira kungwarira panguva yekushandisa?

Kune ma corten steels, anowanzobatwa pamusoro uye haagone kusangana ne acidic kana alkaline corrosive substances. Mukuwedzera, munzvimbo dzinotyisa, matanho ekudzivirira anowirirana anofanirwa kutorwa kuti adzivise kuora. Kudzivirira ngura, tsvina uye ngura pane anti-rust layer inofanira kubviswa. Panguva imwecheteyo, iyo kabhoni yemukati mune yakabikwa zvinhu inofanirwa kudzorwa zvakanyanya, uye yayo kemikari kuumbwa uye michina zvinhu zvinofanirwa kudzorwa. Kunyanya mukugadzirisa kwekugadzira, yakakwirira-simba, simbi isingagadzike inofanira kusarudzwa. Kune corten simbi zvikamu, ukobvu uye uremu hwazvo zvinofanirwa kuongororwa nguva nenguva kudzivirira ngura.

Mhedziso

Kubuda nekuvandudzwa kwecorten simbi kunoratidza kukura kukuru kweindasitiri yesimbi yeChina uye kwave chiratidzo chakakosha cheindasitiri yesimbi yeChina. Kushandiswa kwe corten simbi kunonyanya kuiswa muminda yekuvaka, zvivakwa zvemugungwa nemimwe minda, uye kunyangwe corten simbi yakashandiswa zvakanyanya muindasitiri yekuvaka, nzvimbo yayo yekushandisa ishoma nekuda kwekupokana kwecorten simbi pachayo nezvimwe. zvinhu. Semuenzaniso: mapuratifomu ekumahombekombe, nharaunda dzemugungwa dzine corrosiveness yakasimba yegungwa. Naizvozvo, nzira dzekuvandudza dze corten simbi ndeidzi: hot-dip zinc, inopisa-dip aluminium, nezvimwewo, kutsiva yechinyakare corten simbi. Nekuvandudzwa kweindasitiri uye kuvandudzwa kwekuziva kwevanhu nezvekuchengetedzwa kwezvakatipoteredza, corten simbi yakashandiswa zvakanyanya muindasitiri, kuvaka uye mamwe maindasitiri, kuwana kukunda-kukunda mamiriro munharaunda uye hupfumi.
