Corrosion uye Dziviriro yeChannel Steel
Channel simbi isimbi yakareba mitsetse ine groove yakaita muchinjiko-chikamu, ndeye carbon structural simbi yekuvaka nemichina. Icho chikamu chakaoma simbi ine groove yakaita muchinjiko-chikamu. Channel simbi inonyanya kushandiswa mukuvaka zvivakwa, kugadzira mota, uye zvimwe zvivakwa zveindasitiri, uye inowanzoshandiswa pamwe chete neI-matanda. Nekuda kweiyo yakasarudzika metallographic chimiro uye pamusoro passivation firimu, chiteshi simbi kazhinji yakaoma kuita kemikari maitiro nepakati uye kusvibiswa, asi haigone kusvibiswa pasi pemamiriro ese. Munguva yekushandiswa kwechiteshi chesimbi, matambudziko akasiyana-siyana anogona kusangana, uye ngura ndeimwe yenyaya dzinonyanya kukosha. Corrosion yechiteshi simbi inowanzokonzerwa nezvikonzero zviviri zvinotevera.
1. Chemical corrosion: Oiri mavara, guruva, acids, alkalis, munyu, nezvimwewo zvakanamirwa pamusoro pechaneli simbi inoshandurwa kuita corrosion media pasi pemamwe mamiriro ezvinhu, uye inogadzirisa kemikari nezvimwe zvikamu muchiteshi chesimbi, zvichikonzera kuora kwemakemikari uye. rusting; Akasiyana-siyana anokwenya anogona kukuvadza iyo passivation firimu, kuderedza kugona kwekudzivirira kwechiteshi simbi, uye kuita nyore nemakemikari media, zvichikonzera kemikari corrosion uye ngura.
2. Electrochemical corrosion: Zvimedu zvinokonzerwa nekubatana nekabhoni simbi zvikamu uye kuumbwa kwebhatiri rekutanga rine corrosive media, zvichiita kuti electrochemical corrosion; Kusungirirwa kwezvinhu zvinoita ngura zvakadai sekucheka slag uye kupfapfaidza kune inopisa svikiro inoumba bhatiri rekutanga, zvichiita kuti electrochemical corrosion; Kuremara kwemuviri (undercuts, pores, kuputika, kushaya kusanganiswa, kushaikwa kwekupinda, nezvimwewo) uye kukanganisa kwemakemikari (coarse grain, segregation, etc.) munzvimbo yewelding inoumba bhatiri rekutanga rine corrosive medium, zvichiita kuti electrochemical corrosion. .
Naizvozvo, matanho ese anoshanda anofanirwa kutorwa panguva yekugadziriswa kwechiteshi chesimbi kudzivirira kuitika kwemamiriro ekuora uye induces zvakanyanya sezvinobvira. Imwe nzira ndeye kushandisa aluminium spray coating. Kupfapfaidza aluminium coating uye kuvhara ne-anti-corrosion coating kunogona kurebesa hupenyu hwesevhisi yejasi. Kubva kune theoretical uye inoshanda mashandisiro ekushandisa, zinc kana aluminium yakapfapfaidza coatings ndiyo yakanakira yepasi layer yeanti-corrosion coatings; Iyo aluminium spray coating ine simba rakasimba rekubatanidza nesimbi substrate, hupenyu hurefu hwekuputira, uye yakanaka yenguva refu yehupfumi inobatsira; Iyo aluminium spray coating process inochinjika uye inokodzera kuchengetedzwa kwenguva refu kweiyo yakakosha yakakura uye yakaoma kuchengetedza zvivakwa zvesimbi, uye inogona kuiswa pa-saiti.
Imwe nzira ndeye kushandisa galvanized anti-corrosion dziviriro: inopisa-dip galvanized chiteshi simbi inogona kukamurwa kuita inopisa-dip galvanized chiteshi simbi uye inopisa-inoputika galvanized chiteshi simbi zvinoenderana neakasiyana maitiro ekuita. Mushure mekubvisa ngura, zvikamu zvesimbi zvinonyudzwa mune yakanyungudutswa zinc mhinduro kutenderedza 440-460 ℃ kuti ibatanidze zinc layer pamusoro pezvikamu zvesimbi, nekudaro kuzadzisa chinangwa cheanti-corrosion. Mumamiriro ekunze, iyo yakaonda uye dense layer ye zinc oxide inoumbwa pamusoro peiyo zinc layer, iyo inonetsa kunyungudika mumvura uye nekudaro inoita imwe basa rekudzivirira pachiteshi simbi.
Shandong Kungang Metal Technology Co., Ltd. inyanzvi mupombi yesimbi uye zvigadzirwa zveprofile, ine network yekutengesa inofukidza mapurovhinzi akawanda muChina nenyika dzakawanda kunze. Kuburikidza nekushanda nesimba kwevashandi vese uye nekubatana kwehushamwari kwezvikamu zvehanzvadzi, mumunda unoshanduka wemusika wekutenderera kwesimbi, tinogona kunyatsobata ruzivo nemikana, tichiramba tichiunganidza nekuvandudza nekukurumidza, uye takawana budiriro inoenderera uye kukura. Nebasa rakanakisa uye zvigadzirwa zvemhando yepamusoro, takunda kuvimba nevatengi vedu.
